The Mitsubishi warranty stands out in the 2026 new-car market with coverage that extends well beyond basic bumper-to-bumper protection. Its 10-year/100,000-mile powertrain warranty provides long-term coverage for major mechanical components, while additional programs cover corrosion, roadside assistance and limited maintenance.
Mitsubishi’s 2026 Warranty Programs
New-Vehicle Limited Warranty: 5 Years/60,000 Miles
Mitsubishi provides five years or 60,000 miles of bumper-to-bumper coverage, exceeding the stated three-year or 36,000-mile industry standard. The coverage applies to virtually all components when a failure results from a manufacturing defect.
When a covered component fails, an authorized dealership will repair or replace it with authentic OEM parts at no cost. Covered systems include electrical components, air conditioning, steering and suspension. Routine maintenance and wear-and-tear items, including brake pads, wiper blades and tires, are excluded.
Powertrain Limited Warranty: 10 Years/100,000 Miles
The Mitsubishi powertrain warranty provides 10 years or 100,000 miles of coverage for major components including the engine, transmission and transaxle. It also covers the cylinder block, internal lubricated parts, water pump and drive axles when mechanical failures result from factory defects.
However, the 10-year/100,000-mile coverage applies only to the original owner. When the vehicle is sold, subsequent owners receive only the remaining portion of the five-year/60,000-mile warranty period.
For example, buying a three-year-old Mitsubishi with 40,000 miles would leave the new owner with two years or 20,000 miles of powertrain coverage.
Other Mitsubishi Warranty Coverages in 2026
Anti-Corrosion/Perforation Warranty: 7 Years/100,000 Miles
Mitsubishi’s anti-corrosion/perforation limited warranty lasts seven years or 100,000 miles. The coverage applies to metal rust-through that penetrates the vehicle’s outer body sheet metal panels, rather than superficial surface rust.
Damage caused by rock chips, hail or road salt is excluded.
Roadside Assistance: 5 Years/Unlimited Mileage
Mitsubishi provides 24/7 roadside assistance for five years with unlimited mileage. The program covers flat-tire changes, lockouts, emergency fuel delivery, jump-starts and towing to the nearest authorized dealership.
Limited Maintenance: 2 Years/30,000 Miles
For 2024 models and newer, Mitsubishi offers complimentary maintenance for two years or 30,000 miles to support scheduled vehicle care. The program is limited to the original owner and covers three service intervals, including engine oil changes, tire rotations, cabin filters and multi-point inspections.
Mitsubishi Extended Warranty Options
Owners seeking coverage beyond the factory warranty can consider the Diamond Care Protection Plan, which offers three levels of extended protection.
Supreme Plan
The Supreme Plan is Mitsubishi’s highest tier of extended protection. It operates as an exclusionary policy, meaning every component is covered except for a specified list of exclusions.
The plan closely mirrors the factory bumper-to-bumper warranty and covers complex electrical, suspension and high-tech infotainment failures.
Deluxe Plan
The Deluxe Plan is a stated-component policy that includes everything covered by the Powertrain Plan while adding around 700 specific components.
Additional coverage includes the fuel delivery system, steering mechanisms, suspension components, core electrical systems, brake parts and climate control units.
Powertrain Plan
The base Diamond Care tier focuses on components required to keep the vehicle moving. It covers more than 600 specific parts within the engine, transmission and drive axle assemblies.
The plan covers failures such as a blown head gasket or failed continuously variable transmission (CVT), but does not cover an air conditioning compressor failure.
Diamond Care Protection Plan Terms and Benefits
Vehicle Eligibility
A vehicle must still be covered by its original factory warranty to qualify for the Diamond Care Protection Plan. Waiting until the first day of the sixth year makes the vehicle ineligible for the program.
For used vehicles older than 10 years or with more than 100,000 miles, Mitsubishi recommends a High-Mileage Plan.
Maximum Coverage Extensions
The Diamond Care Protection Plan can extend coverage to a maximum of eight years or 120,000 miles. Because the extension runs from the vehicle’s original in-service date, the eight-year period does not restart when the extended warranty is purchased.
Mitsubishi does not have a standardized pricing structure for the plan, so buyers must obtain a quote directly through a dealership’s finance department.
Additional Benefits
All official Mitsubishi extended warranty tiers include 24/7 roadside assistance for the full contract period. Benefits also include towing reimbursement, daily rental-car reimbursement during repairs and trip interruption protection for severe breakdowns that occur away from home.
How to Maintain Mitsubishi’s Warranty
Follow the Maintenance Schedule
Maintaining warranty coverage requires following Mitsubishi’s prescribed maintenance schedule. Engine oil and CVT fluids, for example, must be changed at the specified intervals.
Owners are not required to use a Mitsubishi dealership for basic maintenance, but the independent mechanic or shop should be certified to perform the required work. Keeping detailed, date-stamped receipts is also important for documenting maintenance and showing that replacement parts meet OEM specifications.
When Can the Warranty Be Voided?
Damage resulting from vehicular collisions, severe environmental hazards or bad weather events is excluded. Aftermarket modifications can also affect coverage, with engine modifications and non-approved suspension lifts specifically identified as changes that can void coverage on interconnected components.
Vehicle abuse or abnormal use, including towing a heavy trailer with a crossover or competitive racing, can nullify claims. A salvage or rebuilt title issued by an insurance company following an accident also voids the factory warranty.
Using incorrect engine oil specifications or failing to follow prescribed fluid-change intervals can likewise result in the loss of warranty coverage.
Mitsubishi Warranty vs. Hyundai and Kia
For roadside assistance, Mitsubishi and Hyundai both offer five years with unlimited mileage. Kia’s roadside assistance coverage is capped at 60,000 miles.
Is Mitsubishi’s Warranty Good Enough?
Mitsubishi’s warranty provides extensive coverage, highlighted by its 10-year/100,000-mile powertrain protection for original owners. The coverage also includes five years or 60,000 miles of new-vehicle protection, seven years or 100,000 miles of anti-corrosion coverage and five years of unlimited-mileage roadside assistance.
The powertrain warranty’s downgrade for subsequent owners can affect the vehicle’s value on the used market, but the coverage remains particularly relevant for buyers who plan to keep a new Mitsubishi for an extended period.
For buyers intending to own a new vehicle for up to 10 years, Mitsubishi’s warranty offers substantial protection against covered manufacturing defects and provides a range of additional coverage options through the Diamond Care Protection Plan.
