Which cars have a 10 year warranty?

Hyundai, Kia, and Mitsubishi are the primary mainstream automakers offering a 10-year/100,000-mile powertrain warranty in the U.S. market, with Ram introducing a similar warranty starting with the 2026 model year. These warranties are among the longest in the industry but are specifically limited to major powertrain components, not the entire vehicle.

The most prominent coverage comes from the Hyundai Motor Group. Hyundai's "America's Best Warranty" includes a 10-year/100,000-mile powertrain limited warranty for the original owner, and this coverage extends to the hybrid/electric battery in their electrified models. Kia offers an identical 10-year/100,000-mile limited powertrain warranty on models like the Sportage, Sorento, and EV6.

Mitsubishi provides a 10-year/100,000-mile powertrain limited warranty, which also covers the high-voltage battery in the Outlander Plug-in Hybrid. In a significant move for the truck segment, Ram has announced it will introduce a 10-year/100,000-mile powertrain warranty beginning with the 2026 model year trucks.

Outside the U.S., MG Motor (in the UK and Ireland) offers a unique "Service Activated" warranty. The standard warranty is 7 years, but it can be extended to 10 years if the vehicle is serviced annually at an MG authorized dealer, effectively creating a decade of coverage.

It is critical to understand these are powertrain warranties. They cover the engine, transmission, drive shafts, and related internal parts. The more comprehensive "bumper-to-bumper" coverage, which includes electronics, suspension, and interior features, is typically 3 to 5 years. Most 10-year powertrain warranties are also non-transferable in full; for second owners, coverage often drops to 5 years/60,000 miles.

Dealers sometimes provide their own longer warranties. You may find certified pre-owned (CPO) programs or dealer-offered lifetime powertrain warranties on specific vehicles, but these are separate from the manufacturer's standard policy. Always verify the exact terms and conditions in the manufacturer's official warranty booklet, as programs can and do change.

As a Hyundai Tucson owner for the past four years, the 10-year warranty was a major deciding factor. It gave me peace of mind, especially with the turbocharged engine. I’ve only used it for a minor transmission sensor issue, but the process was straightforward. The key thing I tell friends is to read the manual’s warranty section. It clearly lists what’s covered under the powertrain part versus the shorter basic warranty. It’s not a “fix everything for a decade” card, but for the big, expensive mechanical pieces, it’s incredibly reassuring.

Working at a dealership, I explain this warranty daily. Customers often misunderstand it. They think everything is covered for ten years. I clarify: the powertrain warranty is for the heart of the car—the engine block, cylinders, transmission gears. Your infotainment screen, power seats, or air conditioning after year 3? That’s under the shorter comprehensive warranty. Also, it’s crucial to follow the factory maintenance schedule using certified technicians. Missing oil changes or using an uncertified shop can void that long-term coverage. For a second buyer, the warranty usually shrinks to 5 years, which affects the car’s resale value.

If you plan to keep a vehicle long-term, this warranty directly impacts cost of ownership. Knowing the major components have a safety net reduces anxiety about catastrophic repair bills down the road. However, don’t let it be the only factor. Research the brand’s reliability history too. A long warranty on a problematic model means more trips to the service department, even if it’s covered. For brands like Kia and Hyundai, their decade of offering this has improved consumer perception significantly. It signals confidence in their product’s durability, which is a strong message in the market.

I’m comparing a Hyundai Santa Fe, a Kia Sorento, and a Toyota Highlander. Toyota only offers a 5-year powertrain warranty, but it has a reputation for reliability. The Korean brands offer double the powertrain coverage. My question is: is the longer warranty compensating for something, or is it pure value? Talking to mechanics and reading owner forums, the consensus is that modern engines from these companies are solid. The warranty is a competitive advantage. For me, the 10-year coverage is a financial risk mitigator. It makes the Sorento or Santa Fe more attractive, provided I keep up with maintenance and plan to own it for at least 7-8 years to truly leverage the benefit.
