California GM Vehicle Owners To Get Updated Warranty Information

GM has issued a new Customer Satisfaction Program, tagged as CSP N252494770, aimed at informing vehicle owners in California of recent updates to state warranty provisions.

The new CSP was released in June of 2025 and applies to all GM vehicles sold in California produced between the 2018 and 2025 model years with a Gross Vehicle Weight (GVW) rating under 10,000 pounds.

This update aligns GM documentation with amendments made to the California Song-Beverly Act (SBA), a state law that protects consumers who buy or lease new or used products, especially when those products include a written warranty. The SBA is best known for its “lemon law” provisions, which apply to vehicles.

Notably, the law now requires consumers to send GM a written notice before filing a lawsuit seeking a vehicle repurchase. Failure to do so may prevent the consumer from pursuing civil penalties in court.

The new CSP states that GM will mail an updated warranty insert and owner’s manual supplement to affected vehicle owners. The updated warranty insert will be provided in both English and Spanish. The insert materials outline the updated consumer rights and detail how GM and its repair facilities must respond to warranty claims under California law. Dealers are instructed to print and insert the appropriate manual pages into the owner’s manual during service visits. This measure is strictly informational and ensures that owners are aware of their rights and GM’s obligations under the revised California warranty law.

The insert specifically mentions California Civil Code Section 1793.22(b), which is part of the California Lemon Law and explains when a car is legally considered a “lemon.” According to this section, a new vehicle is presumed to be a lemon if, within 18 months of delivery to the buyer or within 18,000 miles on the odometer (whichever comes first), the car has a significant defect covered by the warranty that the manufacturer or its repair shop can’t fix after a reasonable number of tries. If these conditions are met, the law presumes the vehicle is defective, and the consumer may be entitled to a refund or replacement under the Lemon Law.
