Can recall 22V903 make my CT4 a lemon in California?

Not by itself. A recall repair that fails, or repeat dealer visits for the same defect, can support a California lemon law claim.

Recall 22V903000 does not automatically make your CT4 a lemon. California's Song-Beverly Act asks two questions: does a warranty defect substantially impair the vehicle's use, value or safety, and did the manufacturer fail to fix it in a reasonable number of tries (Civ. Code 1793.2(d))?

A headlight, wiper or visibility defect on the 2021-2023 Cadillac CT4 can make night or rain driving unsafe, and repeat repairs for the same problem count toward a lemon law claim.

This recall is handled by an over-the-air software update, so many owners never visit a dealer. If the problem returns after the update, take the 2021-2023 Cadillac CT4 to the dealer and make sure the visit is written up on a repair order. An update that does not work is still a failed repair.

Earlier campaigns on these vehicles involving the same component: 22V827000.

Civil Code 1793.22(b) sets out a presumption that applies in the first 18 months or 18,000 miles: two or more repair attempts for a defect likely to cause death or serious bodily injury, four or more attempts for the same defect, or more than 30 total days out of service for repairs. Written notice to the manufacturer is required in some cases. Owners outside that window can still have a claim.

An owner who prevails in a lemon law case can recover reasonable attorney fees and costs from the manufacturer (Civ. Code 1794(d)). You pay nothing, win or lose. We are paid only if you win, and the manufacturer pays our fees, including in settlements. If a case is lost, our firm covers the costs.
