A powertrain warranty covers the expensive parts — engine, transmission, drive components. It's also the clearest statement a manufacturer makes about how long it expects its own product to last. Here's what they actually commit to.
| Powertrain cover | Brands | Who |
|---|---|---|
| 10 yr / 100,000 mi | 4 | Genesis, Hyundai, Kia, Mitsubishi |
| 8 yr / 100–150,000 mi | 1 | Tesla (battery & drive unit) |
| 6 yr / 70,000 mi | 3 | Acura, Infiniti, Lexus |
| 5 yr / 60,000 mi | 85 | The standard |
| 4 yr / 50,000 mi | 10 | BMW, Audi, Cadillac, Jaguar, Land Rover… |
The luxury brands cover you least
This is the part that catches people out. BMW, Audi, Cadillac, Jaguar and Land Rover sit at four years and 50,000 miles — a year and 10,000 miles below the eighty-five-brand standard.
You pay the most and you're covered for the shortest time, on cars whose out-of-warranty repairs are the most expensive in the market. That combination is why a six-year-old German luxury car is cheap to buy and frightening to own.
Note that the Japanese luxury brands split from the Europeans here. Acura, Infiniti and Lexus all extend to six years and 70,000 miles.
The Korean ten-year warranty was a strategy
Genesis, Hyundai and Kia at ten years and 100,000 miles is double the market standard. It wasn't generosity — it was how they broke into a market that didn't trust them.
In the late 1990s Hyundai had a reputation problem, and the fix was to remove risk from the buyer entirely. Ten years is long enough that the warranty covers the entire period most owners keep a car. It worked, and Mitsubishi followed the same route for the same reason.
The catch is one buyers routinely miss: on all three Korean brands the ten-year term is for the original owner only. Buy one used and you typically inherit five years and 60,000 miles. The headline number is a new-car sales tool, not a used-car feature.
What this means used
Check whether any cover transfers, and on what terms. Powertrain warranties usually transfer at reduced length. Getting the specifics in writing before you buy is worth doing, because "it's still under warranty" is one of the most common things a seller gets wrong in good faith.
The in-service date starts the clock, not the model year. A 2021 car that sat on a forecourt until 2022 has a different expiry date from an identical one sold in 2020. That date is tied to the VIN, not the badge.
Short warranty means budget differently. On a four-year German car you're out of powertrain cover at the point where the complaint curve starts climbing — around the six-year mark, as we found in when cars start having problems. That overlap is exactly where the bills land.
Confirm the specific car. Warranty status, in-service date and open recall campaigns all attach to the VIN rather than the model. A VIN check gives you the build and history in seconds, and a dealer can confirm remaining cover from the same number.
Frequently asked questions
Which car brands have the longest warranty?
Genesis, Hyundai, Kia and Mitsubishi cover the powertrain for 10 years or 100,000 miles. Tesla covers the battery and drive unit for 8 years and 100,000–150,000 miles. The market standard across 85 brands is 5 years / 60,000 miles.
Do luxury brands have better warranties?
Not the European ones. BMW, Audi, Cadillac, Jaguar and Land Rover cover 4 years / 50,000 miles — below the industry standard — while their out-of-warranty repairs are among the most expensive. Acura, Infiniti and Lexus extend to 6 years / 70,000 miles.
Does the 10-year Hyundai warranty transfer to a used buyer?
Generally not in full. The 10-year / 100,000-mile term applies to the original owner; a subsequent buyer typically inherits 5 years / 60,000 miles. Confirm the specifics in writing before relying on it.
How do I check if a used car is still under warranty?
Warranty runs from the in-service date, not the model year, and both attach to the VIN. A dealer can confirm remaining coverage from the VIN, and a VIN check will show you the build details and any open recall campaigns at the same time.

In Florida, Two Thirds of Your Premium Protects Other People's Cars
Everyone knows Florida insurance is expensive. Nobody says which part of the bill is expensive. I split the premium into its components by state and the answer isn't the part that covers your car.
