As of 2015, new Hyundai cars carry a limited powertrain warranty covering 10 years or 100,000 miles; whichever comes sooner; and also come with a five-year, 60,000-mile new vehicle limited warranty covering nearly all original equipment parts and systems. The 10-year, 100,000-mile powertrain warranty is the industry's longest and highest-mileage.
South Korean automaker Hyundai and its sister brand Kia can rightfully make claim to tying for the longest and most comprehensive new car warranty among all car brands in the United States. Standard on all models, the 10-year or 100,000-mile limited powertrain warranty covers the original owner only and guarantees against defects in the car's engine, transmission and transaxle.
The second tier of warranty transfers to second or subsequent owners and covers the powertrain as well as nearly all parts and systems bumper to bumper for five years or 60,000 miles. A few items, such as the radio, exterior finish, battery and navigation system, carry lower time or mileage caps.
A seven-year, unlimited-mileage warranty guarantees against perforation and corrosion, while hybrid models have a lifetime warranty for their hybrid battery packs. Other hybrid car systems such as the starter, generator, engine control unit and transmission fall under the same 10-year powertrain warranty as standard gas-powered models. As for emissions-related systems, the federal 50-state emissions control systems are warrantied for eight years or 80,000 miles, while cars meeting California's more stringent emissions requirements carry a seven-year, 70,000-mile warranty.
All Hyundai warranty coverage requires the owner to follow proper maintenance guidelines as laid out in the owner's handbook and does not cover damage that results from misuse or neglect.
