Lemon Car Lawyers Explain: When You’re Entitled to a Refund

If your “new” car has spent more time in the shop than in your driveway, you may be wondering when California’s Lemon Law entitles you to a refund. The short answer: when a vehicle covered by a manufacturer’s warranty has a serious defect that the manufacturer or its authorized dealer can’t fix within a reasonable number of attempts. Below, ZapLemon’s lemon car lawyers explain how refunds work, which defects commonly qualify, and what steps to take next—without the legalese.

Do You Qualify for a Lemon Law Refund in California?

California’s Song-Beverly Consumer Warranty Act (the “Lemon Law”) protects buyers and lessees of vehicles that come with a manufacturer’s warranty—new or used, so long as the defect appears during the warranty period. If a defect substantially impairs the vehicle’s use, value, or safety, and the manufacturer (through an authorized dealership) can’t repair it after a reasonable number of attempts, the law may require the manufacturer to repurchase (buy back) or replace the vehicle. Some small business vehicles also qualify, depending on weight and fleet size.

What counts as a “reasonable number” isn’t the same in every case, but California has helpful guidelines. There’s a legal presumption of a lemon if, within the first 18 months or 18,000 miles from delivery: the dealer tried to fix the same problem 4 or more times; or 2 or more times for a defect likely to cause serious injury or death (think brakes or steering); or the vehicle was out of service for repairs for 30 or more cumulative days. You can still qualify outside those markers—they just make your case easier to prove.

A refund (repurchase) typically includes your down payment, monthly payments already made, sales tax, license and registration fees, and certain incidental expenses like towing or rental cars caused by the defect—minus a “mileage offset” for the use you got before the first repair attempt for the main defect. The mileage deduction is based on miles driven before the first relevant repair, not the entire time you owned the car. Finance charges, aftermarket add-ons, or negative equity from a trade-in may be treated differently, so results vary. Replacement vehicles and “cash-and-keep” settlements are also possible paths, depending on the facts.

Common Defects, Repair Attempts, and Next Steps

Defects that often lead to lemon claims include transmission slipping or hard shifting, engine stalling or loss of power, brake failures, electrical system shorts, steering issues, repeated check-engine lights, coolant or oil leaks, and airbag or seatbelt malfunctions. Infotainment or A/C problems can qualify too if they’re persistent and seriously affect use or value—for example, a draining battery from software faults or a navigation unit that repeatedly freezes and disables backup cameras or safety systems.

To preserve your rights, always present the vehicle to an authorized dealership for warranty repairs—independent shops won’t count for lemon repair attempts. Each time, describe the symptoms clearly, ask the advisor to list your concerns on the repair order, and keep copies of all work orders and invoices showing dates, mileage, and the technician’s findings. Track downtime days, loaner or rental car expenses, and any towing costs. If the same issue returns, reference the earlier repair orders and ask the dealer to note it as a repeat concern.

If repairs are dragging on, consider opening a case with the manufacturer’s customer care line and keep a log of who you spoke with and when. Review your warranty booklet to confirm coverage periods, and check for technical service bulletins (TSBs) that match your symptoms. Don’t ignore safety-related defects—bring the vehicle in promptly and document everything. When in doubt, a consultation with a lemon law attorney can help you understand timelines, what qualifies as “substantial impairment,” and whether a repurchase, replacement, or other resolution may be available for your situation.
