Recurring battery / ev range issues on a Mitsubishi? California's Lemon Law may entitle you to a full refund or replacement — at no cost to you.
Get a Free Case ReviewIf your Mitsubishi is experiencing battery & ev systems problems that your dealer has been unable to permanently fix, you may be entitled to a full repurchase, replacement vehicle, or cash settlement under California's Song-Beverly Consumer Warranty Act — widely regarded as the strongest lemon law in the United States.
Mitsubishi owners across California have successfully recovered the full purchase price of their vehicles after repeated failed repair attempts for battery & ev systems defects. California law requires Mitsubishi to either repair the defect in a reasonable number of attempts or buy the vehicle back — and if the company refuses, it may owe you up to twice the purchase price as a civil penalty.
This page covers everything you need to know: what Mitsubishi battery & ev systems defects qualify, how the lemon law process works, what compensation you can recover, and answers to the questions our clients ask most often. If you've already made multiple dealer visits for the same problem, you may already qualify — read on to find out.
EV battery and drivetrain defects that cause significant range loss, failure to charge, or sudden power cutoff typically meet the substantial impairment standard under California's Song-Beverly Act.
Under California's lemon law presumption, your Mitsubishi is presumed to be a lemon if, within 18 months or 18,000 miles from original delivery (whichever comes first), any of the following apply:
You do not need to satisfy all three criteria — any one of them is sufficient to trigger the presumption. And even if you fall short of these thresholds, you may still have a valid claim if the defect is serious enough or the manufacturer's response was unreasonable.
Mitsubishi models that have generated battery & ev systems complaints in California include the Outlander, Eclipse Cross, Galant, Lancer, and Mirage. If you own one of these models and have returned to the dealer repeatedly for the same issue, your case deserves a professional evaluation.
Battery & EV Systems defects in Mitsubishi vehicles manifest in a variety of ways. The following are the most frequently reported issues by Mitsubishi owners who have pursued — and won — lemon law claims in California. If your vehicle shows any of these symptoms after multiple repair attempts, you likely have a strong claim.
Battery range that falls well below the manufacturer's rated capacity — particularly in the first 1–3 years — is a manufacturing defect, not normal aging. California courts have recognized early range loss as a qualifying defect.
An EV that consistently refuses to accept a full charge — or charges only intermittently — is substantially impaired in its primary function. Multiple failed repair attempts establish a lemon law claim.
EVs that cut power unexpectedly while driving pose the same safety risk as a stalling gasoline engine. This type of defect is treated with urgency under California law.
Battery temperature management failures can cause reduced performance in extreme weather, fire risk, or complete shutdowns. Manufacturers may issue software updates that don't fully resolve the issue.
A faulty charging port that prevents reliable home or public charging renders the vehicle substantially impaired — particularly when the dealer's fixes are temporary.
BMS faults can cause the vehicle to report inaccurate state-of-charge, limit performance unnecessarily, or prevent charging above a certain level. Recurring BMS errors after service support a lemon law claim.
High-voltage system warnings that appear and persist — or recur after dealer service — indicate a serious safety risk in the vehicle's core powertrain.
When a Mitsubishi owner reports a battery & ev systems problem, dealers typically begin with the least invasive steps — diagnostic scans, software updates, fluid changes, or component cleaning — before escalating to part replacement or system overhaul. This incremental approach is common across the industry, but it often means the root cause goes unaddressed over multiple visits while the repair order count climbs.
EV battery defects are frequently addressed through over-the-air (OTA) software updates rather than physical repairs. Even OTA updates count as repair attempts if they fail to resolve the defect. Keep records of all update notifications and their effects.
A critical point many Mitsubishi owners miss: every service visit counts as a repair attempt — including visits where the dealer documents "no fault found" or "unable to duplicate concern." Those visits still establish that you reported the problem and the manufacturer failed to resolve it. If you have three or four repair orders for the same complaint, your case may already meet the legal threshold.
Organize every repair order chronologically. Note the date, mileage, and the exact complaint you described each time. This paper trail is the backbone of your lemon law case and the first thing an attorney will review.
California's Song-Beverly Consumer Warranty Act applies to new and certain used vehicles purchased or leased in California that come with a manufacturer's express warranty. It requires manufacturers — including Mitsubishi — to repair defects that impair the vehicle's use, value, or safety. When those defects cannot be permanently repaired in a reasonable number of attempts, the manufacturer must either replace the vehicle or buy it back.
California's lemon law is significantly stronger than the federal Magnuson-Moss Warranty Act in several important respects:
The law applies to vehicles purchased for personal, family, or household use — including daily commuters. Commercial fleet vehicles are subject to different standards, but single business-use vehicles may still qualify. An attorney can evaluate your specific situation quickly and at no cost to you.
A successful lemon law claim against Mitsubishi can result in substantial financial recovery. California law provides three primary remedies:
Mitsubishi repurchases the vehicle and refunds: your down payment, all monthly payments made, registration and licensing fees, taxes, and incidental expenses (rental cars, towing, repair-related costs) — minus a mileage offset calculated from delivery date to first reported defect.
Mitsubishi provides a comparable new vehicle — same make, model, and trim level — at no net cost beyond the same mileage offset. Replacement vehicles come with a fresh warranty.
Many lemon law cases resolve with Mitsubishi paying a negotiated lump sum while you keep the vehicle. For owners who have grown accustomed to their car or cannot wait for a buyback process, this option often delivers immediate value.
Civil Penalty: If a court finds that Mitsubishi willfully refused to comply with its buyback obligation, California law allows the court to award up to two times the vehicle's purchase price as an additional civil penalty — on top of the buyback amount.
Attorney Fees: Under Song-Beverly, Mitsubishi must pay your reasonable attorney's fees and litigation costs if you prevail. This is what makes the California lemon law work for consumers: you pay nothing to pursue your claim.
If your Mitsubishi has a battery & ev systems defect, the actions you take in the next few days can significantly affect the outcome of your claim. Here is what to do:
Time matters. California's lemon law has a 4-year statute of limitations from when you knew or should have known of the defect — but acting sooner means better documentation, fresher memories, and faster resolution.
Yes. If your EV's range has declined significantly beyond what is expected for normal aging — particularly in the first two to three years — and the dealer has been unable to restore it, you likely have a claim. California courts have recognized early battery degradation as a manufacturing defect.
Yes. Over-the-air software updates and in-dealer reprogramming both count as repair attempts. If an OTA update was pushed to address a known defect and did not resolve it, that event is part of your repair history.
Manufacturers often have internal range tolerance specifications that are more lenient than what they advertise. An attorney can challenge these specifications using the vehicle's own telematics data and industry standards.
Immediately. Sudden power loss at speed is a safety-critical defect. Report it to the dealer right away and document every occurrence. Safety defects require only two failed repair attempts to trigger California's lemon law presumption.
If the charger was sold or provided as part of the vehicle purchase and is defective, it may be covered. However, lemon law claims typically focus on the vehicle itself. Consult an attorney for guidance specific to your situation.
This is a complex question that depends on when the vehicle was purchased and the terms of any bankruptcy reorganization. An attorney can evaluate your options if your EV brand has undergone ownership changes.
