Three things determine whether a vehicle qualifies for a lemon law claim. The vehicle has to be covered by a warranty when the defect appears. The defect has to be one the dealer cannot fix in a reasonable number of attempts, or one that keeps the car out of service for an extended period. And the defect has to affect how you use the car, what it is worth, or whether it is safe to drive.
Most states define "reasonable repair attempts" as four for general defects and two for safety-critical issues. Days out of service typically means 30 cumulative days in the shop within the warranty period. Both clocks reset only after a real fix, not after a "technician could not duplicate" repair order.
A few common misconceptions stop people from filing. Used cars qualify when the original factory warranty is still active or the dealer issued a written warranty at sale. Leased vehicles qualify the same as purchased ones in most states. And you do not need a major safety defect, recurring transmission shifts, electronics glitches, paint defects from the factory, and HVAC failures all show up in our qualifying caseload.
The single most important file you have is the repair order. Each visit, each invoice, each "no problem found" line, they all count toward the statutory threshold. Bring everything you have when you call. If your records are thin, we know how to subpoena what the dealer has on file.
For state-specific qualification rules, see our state lemon law pages, the threshold counts and warranty periods vary by jurisdiction.
