What is the Tanner Act Lemon Law presumption?
The California Tanner Act Lemon Law presumption provides that if your new vehicle has a substantial defect which cannot be repaired after four repair attempts or 30 days in the shop during the first 18 months or 18,000 miles, then it is presumed that the manufacturer had a reasonable number of repair attempts for purpose of the California Lemon Law. If the defect is one that is likely to cause death or serious bodily injury, and you have notified the manufacturer in writing about the serious defect, then only two repair attempts are considered a reasonable number of repair attempts.
