Car warranties can provide both protection for your vehicle and peace of mind. However, when purchasing a new car, you’ll discover that most factory coverage expires after three years. If keeping your vehicle protected for as long as possible is a priority, this guide will help you find the longest car warranty.
Our research team has taken a look at both the best new car warranties and the best extended car warranty companies to see which ones offer the most extensive – and longest – coverage. When looking at your warranty options, it’s best to compare free quotes from multiple providers.

What Is A Car Warranty?
A car warranty is a vehicle service contract stating that a car manufacturer or third-party provider will pay for any repairs and part replacements that are required due to a car’s mechanical failure or history of poor workmanship. Warranty providers will not cover damages caused by auto accidents or environmental factors, as auto insurance takes care of that.
Factory Warranties
New vehicles come with a factory warranty, which is usually a combination of a few different warranties that the dealership packages into the price of a new car. Also called manufacturer warranties, these often include certain types of protection plans and perks:
- Bumper-to-bumper warranty: Covers all vehicle components minus a few exclusions
- Powertrain warranty: Covers the engine, transmission, and drivetrain
- Corrosion warranty: Covers corrosion and rust perforation
- Roadside assistance: Usually includes towing and rental car coverage
Some manufacturers, like Tesla, include warranties for specialized electronic components as well. Popular automakers like Ford, Chevrolet, Jeep, and Ram all offer 3-year/36,000-mile bumper-to-bumper coverage and 5-year/60,000-mile powertrain coverage. Other manufacturers offer bumper-to-bumper warranties that last up to five years and powertrain warranties that can last up to 10.
Extended Warranties
While extended warranty plans can be purchased from the manufacturer, there are many third-party warranty companies on the market. Most aftermarket providers offer several different levels of coverage to choose from, including exclusionary bumper-to-bumper coverage, basic powertrain coverage, and mid-tier stated-component coverage.
Keep in mind that car warranties don’t usually cover wear-and-tear components like brake pads, or routine maintenance services like oil changes. Some automakers and aftermarket providers will offer maintenance packages that cover items like these at an additional cost.
Based on a survey our team conducted in 2021, most respondents decided to purchase an extended warranty with CarShield, while Endurance and Carchex rounded out the top three.
Longest Factory Car Warranties
Our research team reviewed the best new car warranties and found that Hyundai, Kia, Genesis, and Mitsubishi are your best bets for the longest coverage terms.
New Car Warranty Manufacturer | Bumper-to-Bumper | Powertrain | Corrosion | Roadside Assistance |
---|---|---|---|---|
Hyundai | 5 years/60,000 miles | 10 years/100,000 miles | 7 years/unlimited miles | 5 years/unlimited miles |
Genesis | 5 years/60,000 miles | 10 years/100,000 miles | 7 years/unlimited miles | 5 years/unlimited miles |
Kia | 5 years/60,000 miles | 10 years/100,000 miles | 5 years/100,000 miles | 5 years/60,000 miles |
Mitsubishi | 5 years/60,000 miles | 10 years/100,000 miles | 7 years/100,000 miles | 5 years/unlimited miles |
Hyundai: Longest Car Warranty
Among the top automakers, offering bumper-to-bumper coverage for 5 years/60,000 miles and powertrain coverage for 10 years/100,000 miles has become the industry standard. The Hyundai warranty mirrors these standards.
Hyundai calls its factory coverage plan “America’s Best Warranty,” and the company sets itself apart with a corrosion warranty that has no mileage limit. This warranty lasts for seven years, making this factory warranty the longest warranty on the market. Additionally, Hyundai vehicles are the third-most reliable out of 32 major automaker brands, according to the J.D. Power 2022 Vehicle Dependability StudySM. With the five-year bumper-to-bumper coverage on a very reliable vehicle, Hyundai car owners can drive with peace of mind for years.

Genesis: Most Protection With Unlimited Miles
Because Genesis is Hyundai’s luxury brand, the coverage terms of its factory warranty are just as generous as its parent company. Its powertrain coverage is the same 10-year/100,000-mile warranty as Hyundai’s. Genesis also puts no mileage cap on its corrosion warranty or the bundled roadside assistance.
According to J.D. Power, Genesis is right under Hyundai in terms of reliability. So, when driving – even years from now – you’ll have less to worry about than the average driver.

Kia: Most Reliable Car Brand
Kia’s factory warranty is fairly similar to the coverage both Hyundai and Genesis offer. Bumper-to-bumper coverage is 5 years/60,000 miles and the powertrain warranty lasts for 10 years/100,000 miles. But Kia offers shorter terms for its corrosion warranty and roadside assistance. Corrosion coverage lasts for 5 years/100,000 miles and roadside assistance lasts for 5 years/60,000 miles.
J.D. Power gives Kia the number one spot in vehicle dependability. The average repair costs for a Kia is $474 per year, according to RepairPal. Yet the long warranty is still a welcome benefit considering that AC compressor replacements can cost up to $1,921 out of pocket and fuel evaporative canister replacements can run up to $552 for certain Kia vehicles.

Mitsubishi: Best For Warranty Needs
Mitsubishi also offers lengthy terms for its limited warranty. Its bumper-to-bumper and powertrain warranties have the same coverage terms as the other three car makers mentioned. It’s worth noting that J.D. Power ranks Mitsubishi beneath 13 other car brands for dependability, just slightly above the industry’s average.
Additionally, RepairPal shows Mitsubishi vehicles having average annual repairs of up to $535, which is above average costs for ownership. Having a long warranty can help you maintain peace of mind if your Mitsubishi ever needs repairs.
