At Mission Viejo Kia, part of the Patterson Autos family, we know how much peace of mind matters when buying a new or used vehicle. Kia’s 10-year/100,000-mile powertrain warranty is one of the top reasons drivers trust the brand. But what does it really cover? How does it work with pre-owned models? And is it better than what competitors offer? Let’s break it down in this FAQ-style guide.

 What does Kia’s 10-year powertrain warranty actually cover?

Kia’s 10-year/100,000-mile limited powertrain warranty covers the engine, transmission, and transaxle. This includes components like:

• Cylinder blocks and heads

• Timing gears and gaskets 

• Oil pump, water pump

• Transmission case, torque converter, and internal parts 

 How long does Kia’s powertrain warranty last?

The warranty lasts 10 years or 100,000 miles, whichever comes first. It starts from the vehicle's original in-service date. If you reach 100,000 miles in six years, that’s when your coverage ends. 

 Does Kia’s powertrain warranty transfer to a second owner?

 No. The entire 10-year/100,000-mile powertrain warranty is only for the first owner. If the vehicle is sold, the powertrain coverage drops to 5 years or 60,000 miles for subsequent owners—unless it’s a Kia Certified Pre-Owned (CPO) vehicle (more on that below).

 What voids the Kia powertrain warranty?

Several factors can void your powertrain warranty, including: 

• Failing to perform required maintenance

• Using non-Kia-approved parts or fluids 

• Unauthorized modifications

• Damage from accidents, racing, or environmental exposure 

• Salvage title or odometer tampering

Staying on top of your service schedule at certified dealers like Mission Viejo Kia helps protect your warranty coverage.

 Does the powertrain warranty include engine and transmission?

Yes. These two components are the core of the powertrain and are fully covered under the 10-year/100,000-mile warranty. If your engine or transmission fails due to a defect in materials or workmanship, Kia covers the repairs. 

 Is Kia’s powertrain warranty better than Hyundai’s?

Kia and Hyundai offer nearly identical warranties—both provide 10-year/100,000-mile limited powertrain warranties to original owners. Where they may differ is in dealer service, perks, and overall experience. At Mission Viejo Kia, we pride ourselves on making the most of Kia's strong warranty by offering expert care and personalized service.

Are hybrid and EV components included in the warranty?

Yes. Kia includes a separate warranty for hybrid and electric vehicle components. This includes: 

• Electric motor

• Battery pack 

• Charging system 

 For EVs like the EV6, the battery warranty also runs 10 years/100,000 miles, which is among the industry's best. For hybrid models, coverage may vary slightly depending on the year and model.

What does Kia's powertrain warranty not cover?

Kia’s powertrain warranty does not cover: 

• Routine maintenance (oil changes, filters, fluids)

• Wear-and-tear items (brake pads, wiper blades, tires) 

• Damage from misuse or neglect

• Issues from non-Kia parts or repairs 

Think of it as a “major mechanical” coverage—if it’s a big, internal moving part of the engine or drivetrain that fails unexpectedly, it’s likely covered.
