The only used vehicles which would qualify under the Lemon Law are true Certified Pre-Owned (CPO) vehicles or dealership demonstrators. A "true" CPO is one that is purchased from a new car dealership of the same brand. For example, a CPO Toyota can only be purchased from a Toyota dealership. Dealership demos are owned by the dealership and have never been sold to the public. Despite being technically used, the vehicle can still qualify. This could also include dealership owned vehicles being driven by dealership employees.
Generally, under the California Lemon Law, a vehicle may qualify for a refund or a replacement if prior to 18 months of ownership or less than 18,000 miles, it meets just one of the following criteria:
-The vehicle has the same problem repaired FOUR or more times;
-The vehicle has the same problem repaired TWO or more times and the problem is a major safety defect;
-The vehicle is out of service for THIRTY or more total days.
If the vehicle is older than 18 months, or has more than 18,000 miles, the above criteria become guidelines. In this instance, the question is whether the dealership has had a reasonable opportunity to repair the vehicle, or whether the vehicle has been out of service an unreasonable number of days.
The problems with the vehicle must substantially impair the use, value, and safety of the vehicle and must have originated during the original manufacturer's warranty.
The amount of time can vary, but the average case should take about 90 days to be fully completed, assuming litigation is not necessary. This is an average; some cases take longer for various reasons, and some take less time. If the case needs to be litigated, it could take substantially longer to be completed.
