Mitsubishi I-Miev warranty claim denied?

138 manufacturer communications on file 5 warranty extensions / campaigns 2010–2017 model years covered

A denied warranty claim can feel like the end of the road, but for Mitsubishi i-MiEv owners (2010–2017), it often isn't. Manufacturers are required to file service communications with the National Highway Traffic Safety Administration, and for this model, 138 such communications are on record. Five of them are formal warranty extensions or service campaigns, covering components such as the on-board charger and the main drive lithium-ion battery, which Mitsubishi extended to 8 years or 100,000 miles in one documented case.

When a dealer denies a claim, it doesn't always mean the underlying defect isn't documented or that the decision is final. Denials are sometimes based on incomplete records, missed extended-coverage programs, or a straightforward misapplication of the terms. Reviewing your denial against the manufacturer's own published bulletins can clarify whether the issue you experienced matches a known, documented problem.

ClaimRight offers a free assessment of your denial, comparing your situation against the manufacturer's filed communications for your vehicle. There's no cost to find out what your options are, and no obligation to proceed.

What Mitsubishi has documented for the I-Miev

Filed with NHTSA by the manufacturer. Warranty extensions are the strongest signal — the manufacturer acknowledging a defect and extending coverage for it.

Common questions

Why would Mitsubishi deny a warranty claim on an i-MiEv?
Claims can be denied for several reasons, including the dealer determining the issue falls outside standard coverage, insufficient documentation of the defect, or the service advisor not checking for applicable extended-coverage programs. Some denials stem from the claim not being matched to a manufacturer-issued bulletin or warranty extension that may actually apply to the vehicle's specific component or model year.
Does Mitsubishi have known issues with the i-MiEv battery or charger?
Mitsubishi has filed manufacturer communications with NHTSA documenting warranty extensions for certain i-MiEv components. These include extensions related to the on-board charger and the main drive lithium-ion battery, with battery coverage noted at 8 years or 100,000 miles in one filing. Whether a specific vehicle qualifies depends on its model year, production date, and service history.
Can a denied warranty claim be reconsidered after the dealer says no?
Many denials can be reviewed again, particularly if new documentation, a matching manufacturer bulletin, or an applicable extended-coverage program comes to light. Owners generally have the option to request a second review, escalate within the dealership or manufacturer, or consult with a consumer advocacy service to compare the denial against publicly filed manufacturer records before deciding how to proceed.
