Short version: Under factory warranty, a Kia or Hyundai hybrid is generally fine — drive it, service it, keep your paperwork. What we’d think hard about is the decade after that. Our concerns aren’t about how the cars drive; they’re about parts availability as these age, diagnostic tooling that’s difficult for independent shops to get, and an architecture that keeps being redesigned while Toyota refined one system for thirty years. To make that concrete: a Hyundai Ioniq Hybrid has three clutches where a Prius has none, and its 12-volt battery — the cheapest, most routine consumable on any hybrid — is built inside the high-voltage battery assembly, so it isn’t a part you can buy. If you own one, the highest-value thing you can do is protect the warranty and decide early how long you plan to keep it.

We get asked about these constantly, and we’ve been putting off writing this one because there’s no way to do it without sounding negative. So let’s set the frame honestly first.

These are not bad cars to drive. They’re well equipped, they’re efficient, they’re often a lot of vehicle for the money, and the people buying them are making a perfectly reasonable decision with the information they have. Our concerns are almost entirely about the second half of the car’s life — and they come from servicing this stuff for about a decade, not from reading about it.

Also, the standard caveat: you’re reading a shop’s opinion. We see the cars that break. There are certainly plenty of Kia and Hyundai hybrids out there running fine that we will never meet. Take what follows as “things we’ve run into often enough to have an opinion about,” not “things that will happen to your car.”

The split: under warranty vs. after

Here’s our actual position, as plainly as we can put it.

Under the factory warranty, we tell people they’re probably fine. Drive it. Enjoy it. Get it serviced. The manufacturer is on the hook, and that’s exactly what you paid for.

After the warranty, we wouldn’t own one ourselves. That’s a preference, not a prediction about your car. But it’s a strongly held one, and everything below is why.

The useful consequence of that split: the most important decision you make about a Kia or Hyundai hybrid isn’t how you maintain it, it’s how long you plan to keep it — and that decision is best made early, while you still have warranty left to sell to the next owner.

Oil intervals: our recommendation is 5,000 miles, and here’s why we hold it

Change the oil every 5,000 miles regardless of what the maintenance schedule allows.

That’s our recommendation across the board, not just for these cars — manufacturers generally moved oil intervals from the 3,000–5,000 range out to 7,500–10,000, and in our experience, engines serviced on the longer intervals show more accumulated wear by 100,000 miles. Plenty of people online disagree with us about this. We’re telling you what we see.

Where it goes from a general preference to something we feel strongly about is when you look at what actually got recalled on these engines. In February 2025, Kia recalled 137,256 vehicles — 2021–2023 Seltos and Soul models with the 2.0L Nu engine — and NHTSA’s recall report describes the problem this way:

“Due to a quality deviation by the piston oil ring supplier, the piston ring may, over time, damage the surface of the cylinder wall. This may lead to increased oil consumption which will eventually result in abnormal noise from the engine and/or illumination of the oil pressure warning light. If the vehicle is continually operated in this condition, engine damage and/or seizure can occur, resulting in loss of motive power.”

Read that sequence again, because it’s the whole argument: oil consumption comes first, and engine destruction comes later. An engine that’s quietly using oil between long service intervals is an engine that can run low without anyone opening the hood. Checking the oil is free.

There’s an important note on scope: that recall is on gasoline Seltos and Soul models, not on hybrids and not on the current turbo hybrid engine. We’re not telling you your hybrid has this defect. We’re telling you why we’re stubborn about oil.

The pattern worth noticing: software that listens for the engine failing

This is the thing we’d most want a prospective buyer to understand, and it’s visible right in the recall paperwork.

For the Theta II engine problems, the fix included the Knock Sensor Detection System (KSDS) — a software update that monitors for the sound of failing connecting rod bearings and warns the driver before the engine seizes.

For the Nu piston-ring recall above, the remedy was to inspect and if necessary replace the engine, and then, in NHTSA’s words:

“As a preventative measure, dealers will also be instructed to install a Piston-ring Noise Sensing System (PNSS) software to provide an early warning light to the driver of potential damage to the engine. If the PNSS software subsequently sets a Diagnostic Trouble Code (DTC), the engine will be replaced.”

Two different engine families, years apart, and in both cases part of the answer is software that listens for the engine destroying itself and tries to catch it in time.

We want to be fair about this: early warning is genuinely better than no warning, and a manufacturer that ships detection and then replaces engines is doing more than one that does nothing. But it is a detection strategy, and it tells you something about the underlying engineering approach that we think buyers should weigh.

What the engine settlement actually says — and what it doesn’t

There’s a lot of loose information circulating about the Kia and Hyundai engine class actions. Here’s what the settlement documents themselves say, because the details matter.

Scope is narrower than people think. The Kia settlement covers 2011–2018 and certain 2019 Optima, 2012–2019 Sorento, and 2012–2018 and certain 2019 Sportage vehicles with 2.0-liter and 2.4-liter Theta II gasoline direct injection engines. Theta II only. If you’ve read that it also covers the Nu and Gamma engine families, that’s incorrect — those engines have had their own separate recalls, which is arguably the more telling fact.

What the lifetime warranty covers. The extension applies to repair, replacement, diagnosis, or inspection of the short block assembly — described in the settlement as the engine block, crankshaft and bearings, connecting rods and bearings, and pistons — for connecting rod bearing failure or associated symptoms.

KSDS is a condition. You must have had the KSDS campaign completed by a Kia dealer to receive the lifetime warranty extension.

The maintenance-records requirement is narrower than the internet suggests. The settlement’s carve-out is for “Exceptional Neglect,” which it defines as: when the vehicle “clearly evidences a lack of maintenance or care for a significant period of time of not less than one (1) year, such that the vehicle appears dilapidated, abandoned, and/or beyond repair,” or where the owner failed to have KSDS installed. Owners are suggested to retain maintenance records, and may be asked for them if Kia believes there’s Exceptional Neglect.

So the formal bar is high — this is not, on paper, “produce every oil change receipt or you’re denied.”

Our opinion on that, clearly labeled as opinion: keep the receipts anyway. Every one of them, organized. Not because the settlement text demands it, but because the gap between what a document says and how a claim goes at a service counter is where people lose. Walking in with complete documentation ends an argument before it starts, and it costs you nothing but a folder.

Separately, and on a much larger scale, Kia and Hyundai set aside roughly $760 million to resolve U.S. class actions related to engine fires, covering on the order of 4.17 million Theta II GDI vehicles. That’s history rather than a live risk on a new car — but it’s the track record, and track record is exactly what you’re buying when you commit to a manufacturer for a decade.

Architecture churn: the thing that actually worries us

This is the technical heart of it, and it’s the reason we keep steering people toward Toyota for long-term ownership.

Toyota has been refining essentially one hybrid architecture for about thirty years. A planetary gearset — the power-split device — blends engine and motor output continuously. There’s no clutch to wear out and no stepped transmission. They’ve iterated on that same fundamental machine across generations and only in recent years introduced a second variant for trucks. Thirty years of the same basic design is thirty years of failures found, parts tooled up, procedures documented, and technicians trained.

Hyundai and Kia took a different path. Their system — TMED, for Transmission Mounted Electric Device — puts the electric motor between the engine and a conventional stepped automatic transmission, where the torque converter would normally be, with an engine clutch to decouple the gas engine. It’s a genuinely clever design and it drives well. It is also a fundamentally different machine from Toyota’s, with wear items Toyota’s architecture simply doesn’t have.

And it keeps changing. The second-generation version of that system, TMED-II, is arriving now, debuting on the 2026 Palisade.

Here’s why that matters to you specifically, and it has nothing to do with which design is better on paper: every new architecture restarts the clock. New parts catalog. New failure modes nobody has documented. New procedures. New tooling. All the accumulated knowledge that makes a fifteen-year-old Prius straightforward to fix is knowledge about that machine, and it doesn’t transfer to a machine built differently.

Toyota spent thirty years letting one system get boring. Boring is the goal. Boring is what you want under your car in year twelve.

If you want to see what that difference actually buys you, look at the Ioniq.

The Ioniq Hybrid: three clutches where a Toyota has none

We keep coming back to the Hyundai Ioniq Hybrid when we explain this, because it’s the clearest side-by-side you’ll find. Same mission as a Prius. Same size. Same buyer. Completely different machine underneath.

Here’s the Toyota, in one sentence: a planetary gearset blends engine and motor output continuously. No clutch. No stepped transmission. The parts that would normally wear — a clutch pack, a torque converter, shift elements — aren’t there to wear, because the design doesn’t use them.

Here’s the Ioniq. The gas engine drives a single dry-plate clutch (the K0). The output of that clutch drives a 32 kW electric motor. The output of the motor feeds a six-speed dry dual-clutch transmission, which has two more clutches inside it. In EV mode the K0 opens and disconnects the engine; when the engine restarts, K0 closes and both power sources feed the gearbox together.

Count them: three clutches, plus the actuators and control software to operate all three. Against zero.

We want to be fair, because this is genuinely clever engineering. A DCT is efficient, it shifts fast, and pairing it with a motor hides the low-speed clumsiness that dual-clutch transmissions are known for. It drives well. Nobody at Hyundai was being lazy.

But every clutch is a wear item, every actuator is a failure point, and every one of those parts is something a Prius owner will never pay for — because on their car it doesn’t exist. The friction discs in a dry dual-clutch are consumable by design. They are supposed to wear out. That’s not a defect; it’s how the part works. It’s just a maintenance category Toyota owners don’t have.

And this isn’t theoretical. In 2018, Hyundai recalled 2017 Ioniq Hybrids because, in NHTSA’s words:

“The Hydraulic Clutch Actuator (HCA) inner oil seal may leak, allowing oil to accumulate in the cap area, possibly resulting in an electrical short.”

The stated consequence: “An electrical short can increase the risk of a fire.” The remedy was to inspect the actuator caps and replace the HCA assembly.

Sit with that for a second. That is a fire-risk recall on a part that only exists because they chose to put a clutch there. There is no hydraulic clutch actuator on a Prius to leak, because there is no clutch for it to actuate. Complexity isn’t just more things to maintain — it’s a larger surface area for things to go wrong in ways nobody predicted.

NHTSA’s owner complaint database is consistent with that theme, though we’ll be straight about the sample size: for the 2018 Ioniq Hybrid there are only about a dozen complaints filed in total, and the largest powertrain group is clutch and clutch-actuator failure, with owners describing violent shifting between the lower gears. A dozen complaints is not a reliability study. It’s a weak signal pointing the same direction as the recall, and we’d rather show you the weak signal and label it than pretend we have data we don’t.

The 12-volt battery lives inside the high-voltage battery

This is the design decision we’d most want a shopper to understand, and almost nobody knows about it before they own the car.

On virtually every hybrid ever built — including every Toyota — there is an ordinary 12-volt battery somewhere in the vehicle. It runs the computers and closes the relays that wake the high-voltage system up. It’s a wear item, it dies every four to six years, and it’s an inexpensive part you can buy at any parts store in America. When your Prius won’t wake up, that battery is usually the reason, and it’s a cheap morning.

The Ioniq Hybrid doesn’t have one. Hyundai’s own owner documentation puts it plainly:

“The 12V battery is integrated into the lithium high voltage battery assembly.”

and, in case there’s any ambiguity:

“This vehicle does not have a replaceable 12V flooded lead acid battery.”

Instead there’s a small lithium-ion 12V battery built into the high-voltage battery assembly under the rear seat, managed by the same battery management system. Because a lithium pack can be damaged by deep discharge, it protects itself: run it down far enough and a relay disconnects it from the car entirely. To get the vehicle to wake up again, you press a 12V Battery Reset Switch on the lower dash and start the car within seconds — if you don’t, it disconnects again to protect itself.

Now think about what that means over a decade of ownership.

The most common consumable in a hybrid — the one part every owner eventually replaces, the cheap and boring one — has been engineered into the most expensive assembly in the car. You cannot walk into a parts store and buy it. A dead-battery no-start, which on a Toyota is a routine, inexpensive visit, becomes a question about a component inside the high-voltage pack.

We don’t think this was a careless decision. Integrating it saves weight, saves space, lets one management system handle everything, and eliminates a lead-acid battery that hybrid owners are famously bad at maintaining. On paper it’s elegant.

It’s just elegant in a direction that isn’t serviceability. And it’s the kind of choice you can only evaluate honestly after ten or fifteen years of these cars aging in the real world — which hasn’t happened yet.

There’s a second recall worth knowing about in the same area of the car. Hyundai recalled 2017–2018 Ioniq Hybrids and 2018 Plug-In Hybrids because the main relay in the Power Relay Assembly could have inadequate contact connections, causing increased electrical resistance. NHTSA’s description of the consequence:

“The increased electrical resistance can overheat the rear seat which is above the PRA, increasing the risk of a fire.”

And here’s the part we’d want to know as an owner: in 2022, Hyundai issued another recall covering vehicles “previously recalled under recall number 18V-704.” The first remedy didn’t settle it.

What it actually costs you

We’re going to talk about this in relative terms rather than dollar figures, on purpose. Parts pricing moves, it varies by region and by who’s doing the work, and a number we print today is wrong within a year. What doesn’t move is the shape of the comparison.

The high-voltage battery is expensive — and here’s the part worth sitting with. It’s costlier to replace than a conventional hybrid pack, and the Ioniq Hybrid’s battery is only about 1.56 kWh. That is a very small battery, a fraction of what’s in an EV. The price isn’t tracking how much battery you’re buying. It’s tracking how the assembly is built, what else is integrated into it, and who is allowed to supply and install it. That last one is the factor buyers never account for, and it’s the tooling-and-parts-access problem from earlier in this article showing up on an invoice.

The 12-volt is where the contrast is sharpest. On a Toyota it’s inexpensive and you can buy one anywhere — genuinely a routine, cheap morning. On an Ioniq Hybrid there’s no equivalent part to price at all, because it isn’t a standalone component you can buy. The cheap fix simply isn’t on the menu, and what replaces it is bound up in the most expensive assembly in the car.

The clutches are a category Toyota owners don’t have. A dry dual-clutch’s friction discs are consumables — they’re designed to wear out — and reaching them is a transmission-removal job, not a bolt-on. That’s costly work on any modern vehicle. The thing to hold in your head is that the Toyota equivalent of this repair doesn’t exist, at any price, because the part isn’t in the car.

Add it up across a decade and you can see the shape of our concern. It isn’t that any single repair is outrageous. It’s that the Toyota architecture removes several entire categories of repair from your life, and the Hyundai/Kia architecture adds them back — on a platform where parts access and tooling are already harder.

If you want real numbers for your specific car and your specific repair, ask us and we’ll price it. That’s a conversation about your vehicle, not a number in an article.

The tooling wall — and why it decides where you’re allowed to go

Buyers almost never think about this before purchase, and it quietly determines your out-of-warranty life.

Most manufacturers make factory diagnostic software available to independent shops by subscription, running on an ordinary PC. Toyota’s Techstream is the example we always point to — Toyota makes repair information and diagnostic tooling genuinely accessible, and in our read they’ve deliberately chosen not to treat that as a profit center. That decision is a large part of why an independent shop can support a Toyota hybrid for twenty years.

Kia and Hyundai run more of their diagnostic ecosystem through proprietary tablet hardware rather than PC-based software, and the cost to acquire and maintain that tooling is high enough that many independent shops don’t carry it. That’s not a moral failing on anyone’s part — but the consequence lands on you, not on the manufacturer. When your shop can’t fully talk to your car, you no longer have a choice about where you get it fixed. You go to the dealer, at dealer rates, on the dealer’s schedule, for as long as you own it.

Ask about this before you buy, not after. It’s a five-minute phone call to any independent shop near you.

Parts availability as the car ages

We’ve run into difficulty sourcing parts for Kia and Hyundai vehicles that are only about ten years old. On the Toyota hybrid side, ten years old is barely middle-aged — parts come from Toyota, from a deep aftermarket, and from multiple hybrid battery rebuilders.

For a car you intend to keep for a decade or more, parts availability isn’t a detail. It’s the difference between a repairable car and a car that’s finished.

The turbo hybrid: what we can and can’t tell you

The current Carnival Hybrid uses a 1.6-liter turbocharged gasoline direct injection engine (1,598 cc) paired with a 74.4 hp permanent-magnet motor, a 270-volt, 1.49 kWh lithium-ion battery, and a six-speed automatic transmission, for about 242 hp combined. Those are Kia’s own published figures.

Two honest observations, and one honest non-answer.

First, this is new technology by the manufacturer’s own account. The Smartstream G1.6 T-GDi is the engine Hyundai Motor Group introduced in July 2019 to debut CVVD — Continuously Variable Valve Duration — which the company announced as a world first. That’s Hyundai’s own framing, in their own press release, and it’s a real engineering achievement. It is also, definitionally, a valvetrain approach that had no field history when it launched.

Second, turbocharging raises the stakes on maintenance. A turbocharger raises underhood temperatures and pressures and puts more thermal stress on the oil. That’s straightforward physics and it’s why we’d hold the 5,000-mile line even harder on a turbo engine than on a naturally aspirated one. Add direct injection, which on many engines brings carbon buildup on the intake valves over time — and note that a hybrid, driven the way hybrids encourage you to drive, may spend a lot of time in exactly the light-load conditions that don’t help.

Third, the non-answer: we don’t know how these hold up long-term, and neither does anybody else. We looked for credible field data on the 1.6 turbo hybrid before writing this and found forum speculation, not evidence. We’re not going to invent a failure rate to fill the gap. The absence of data isn’t reassuring or damning — it’s just the state of things, and it’s precisely the condition described in our article about new cars being dragons. You would be part of how that data gets collected.

Reading your actual warranty

Before anyone sells you an extended service contract, read the coverage table in your own Warranty and Consumer Information Manual. From Kia’s:

Basic (bumper-to-bumper): 60 months / 60,000 miles
Powertrain: 120 months / 100,000 miles — marked Original Owner Only
Audio / Entertainment: 36 months / 36,000 miles. The manual’s language covers the original equipment radio, CD player, rear-seat entertainment system, or navigation system.

Three things fall out of that.

The famous 10-year/100,000-mile number is original-owner-only. If you bought used, it isn’t yours. If you sell, the next owner doesn’t inherit it — which affects your resale value.

The screens really do run out first. Three years on the head unit against five on the basic warranty. On a modern vehicle where the screen controls climate and much of the car’s interface, that’s a real gap, and it’s the gap finance offices lean on when selling coverage. They’re not making it up.

Check your own manual for your own model year. Terms change, and hybrid-specific components and the high-voltage battery carry their own separate coverage. Don’t take a summary — including ours — as the governing document.

If you already own one: the playbook

This is what we’d do, in order.

Decide your exit date now, not later. Our bias is to be out with real margin before the powertrain coverage ends, while the car still has warranty left to sell. If you’d rather keep it longer, that’s a legitimate choice — just fund it deliberately instead of hoping.
Change the oil every 5,000 miles, and check the level between changes. Given what the recalls describe, oil consumption is the symptom you want to catch early. It costs nothing to look.
Service it at the dealer during the warranty years. Not because dealer technicians are better — because it eliminates an argument if you ever need a large claim paid. Come see us after.
Keep every receipt, organized. See above.
Modify nothing, especially anything touching factory wiring. Want a dashcam? Get one that plugs into the accessory socket, comes out in seconds, and requires no installation or modification. A hardwired install is a thread someone can pull on during an electrical claim, and no dashcam is worth that risk on a new car.

Two more that don’t fit the numbered list: get every recall and software campaign done — with these engines, a skipped campaign has been grounds for losing coverage — and learn the factory maintenance schedule from the book in your glovebox well enough to recognize when you’re being sold something that isn’t on it. Service advisors are generally paid on commission. That’s just a fact to hold in mind while someone recommends a flush.

Extended service contracts

Our honest opinion, and it is an opinion: we don’t buy them. In our read they function largely to keep you returning to the dealership, and the money is often better kept in your own account against future repairs.

We’ll also be straight about the limits of our opinion here. On a vehicle this new, nobody — including us — knows what’s going to break or what it will cost. That uncertainty cuts both ways: it’s an argument for coverage as much as against it.

If you’re weighing one, two things decide it more than the price:

Does it restrict where you can have work done? A contract that only pays at the dealer is a contract that chooses your shop for the next decade.
What’s actually excluded? Read the exclusions in full. That’s where these documents live.

And check the term against the factory coverage you already have. Paying for years that overlap coverage you were given is the most common way people overpay.

What we’ll do

We’ll service your Kia or Hyundai hybrid. We’re not refusing the work and we’re not going to lecture you at the counter about a car you already own.

What we’ll also do is tell you plainly when we hit a wall — a part we can’t source, a system we can’t fully access — rather than burning your money learning that in real time. And if you’re still shopping, we’d much rather have that conversation now.

If the engine ever does come apart on you, your position with the manufacturer is dramatically better with a complete, organized service history behind you. That’s the single most useful thing you can control.

Frequently Asked Questions

Do you service Kia and Hyundai hybrids?

Yes. Our specialty is Toyota, hybrid, and EV service, and we work on the Kia/Hyundai hybrid platform. We’ll also tell you honestly when a specific job needs dealer-level diagnostic access we can’t provide.

Will using an independent shop void my factory warranty?

No — federal law protects your right to have routine maintenance performed elsewhere, as long as the work is done properly and you keep records. That said, our practical advice on a brand-new vehicle with a large powertrain warranty is to have covered-period service done at the dealer anyway. Not because it’s legally required, but because it removes an argument if you ever need a major claim paid.

Is the Kia/Hyundai hybrid system reliable?

They generally drive well and the newest engines appear to have moved past the problems of the older Theta and Gamma families. Our concerns are about the second decade rather than the first: parts availability as the cars age, diagnostic tooling that’s hard for independents to get, and an architecture that has been redesigned rather than refined. Under warranty, we tell people they’re probably fine.

What’s actually different about a Kia/Hyundai hybrid versus a Toyota?

Toyota uses a power-split design — a planetary gearset blending engine and motor output, with no clutch and no stepped transmission — refined over about thirty years. Hyundai and Kia use TMED, which places the electric motor between the engine and a conventional automatic transmission with an engine clutch. Both work. But the Toyota system has three decades of documented failures, tooled-up parts, and trained technicians behind it, and the Hyundai/Kia system is now entering its second generation.

Why does the Hyundai Ioniq Hybrid have a clutch when a Prius doesn’t?

Because they’re built on different principles. Toyota’s power-split design uses a planetary gearset to blend engine and motor output, which needs no clutch and no stepped transmission. Hyundai’s design places the motor between the engine and a six-speed dual-clutch transmission, with a separate clutch to disconnect the engine — three clutches in total. The Hyundai approach drives well and shifts quickly. It also adds wear items and failure points that simply don’t exist on the Toyota, including a hydraulic clutch actuator that was recalled on 2017 Ioniq Hybrids over an oil leak that could cause an electrical short and a fire risk.

Is it true the Ioniq Hybrid’s 12V battery is inside the high-voltage battery?

Yes. Hyundai’s own owner documentation states that “the 12V battery is integrated into the lithium high voltage battery assembly” and that “this vehicle does not have a replaceable 12V flooded lead acid battery.” There’s a small lithium 12V built into the high-voltage assembly under the rear seat, plus a 12V Battery Reset Switch on the lower dash to reconnect it if it protects itself by disconnecting. It’s a tidy piece of packaging. It also means the cheapest, most routine consumable on a normal hybrid isn’t a part you can buy separately on this one.

What does a Hyundai Ioniq hybrid battery cost to replace?

It’s an expensive repair — costlier than replacing a conventional hybrid pack, and remanufactured options from independent hybrid-battery specialists are the less expensive route when they’re available. We’re not going to print a figure, because pricing moves and it varies by region and model year; ask us and we’ll quote your actual car. What’s worth knowing regardless of the number: the Ioniq Hybrid’s pack is only about 1.56 kWh, which is very small. The price is driven by how the assembly is built and who’s allowed to supply it, not by how much battery you’re getting.

Should I buy the extended warranty on my new Kia hybrid?

That’s your call and it depends on the specific contract. Before deciding: confirm what it excludes, confirm whether it restricts you to dealer service, and check the term against the factory coverage you already have. Also read your own warranty manual first — the coverage gaps a salesperson describes may be real, but you should see them in the document rather than hear them across a desk.

Does my infotainment screen really only have three years of coverage?

In Kia’s warranty manual, the audio and entertainment system — the original equipment radio, CD player, rear-seat entertainment, or navigation system — is covered for the first 36 months/36,000 miles, while the basic warranty runs 60 months/60,000 miles. Verify the table in your own manual for your model year, but yes, the head unit typically runs out well before the rest of the car.

Can I hardwire a dashcam in my new hybrid?

You can, and we’d advise against it on a vehicle under warranty. Use one that plugs into the accessory socket and requires no modification to the car. On a new vehicle the warranty is most of what you’re relying on, and you don’t want an aftermarket wiring job anywhere near an electrical claim.

How often should I change the oil in a Kia or Hyundai hybrid?

Our recommendation is every 5,000 miles regardless of the longer interval the maintenance schedule may allow — and we’d hold that line especially firmly on a turbocharged engine. Check the level between changes. Given that recent recalls on these engine families describe oil consumption as the early symptom that precedes engine damage, noticing it early is worth a lot.
