When it comes to warranties, the best policy depends on what you need.

 It’s easy to get lost in the weeds, so we rank the policies from outstanding to ordinary based on three major provisions — powertrain, bumper-to-bumper and roadside assistance.

Some automakers offer lengthy powertrain warranties, but that typically covers only the engine, transmission and driveline. By contrast, bumper-to-bumper coverage — often called “basic” warranties — cover everything else — electrical parts, for example — and often include the powertrain if an automaker doesn’t split it out. Then comes other coverage, from roadside assistance to warranties for body panel corrosion and vehicle accessories.

Here’s the lay of the land for each automaker.

The Best

Brands: Genesis, Hyundai, Kia, Mitsubishi and Volkswagen

Why they’re here: Even when you consider their transferability limitations, these are still the best warranties for 2017. The powertrain policies are years ahead of the rest of the industry, and the bumper-to-bumper warranties are equally impressive.

Kia: Five years or 60,000 miles for bumper-to-bumper and roadside assistance, and 10 years or 100,000 miles for powertrain,

Volkswagen: Six years or 72,000 miles for bumper-to-bumper and powertrain on the 2018 Tiguan and Atlas SUVs, which are VW’s only 2018 models on sale at the time of this writing. Roadside assistance on both models is three years or 36,000 miles.
Caveats: The powertrain coverage for Genesis, Hyundai, Kia and MItsubishi isn’t transferrable to subsequent owners, so it drops to five years or 60,000 miles after the first owner, though bumper-to-bumper and roadside assistance have no term reduction. Volkswagen’s…
