Can recall 25V148 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 25V148000 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 transmission defect affects the core job of the 2021 Cadillac CT4: moving reliably. Owners often see the same symptom return after a repair, and those repeat visits are the kind of history California's lemon law looks at.
The recall repair is available at dealers. If it works, great. If the same symptom comes back, the recall visit is one repair attempt and the next visit is another.
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.
In our cases, a recall repair visit counts as a repair attempt, and it's strongest when the owner complained about the problem before the recall came out. A recall shows the defect is real and that enough owners reported it for the manufacturer to issue a fix.
A typical pattern: an owner reports the transmission slipping, and the dealer can't verify it. Six months later, NHTSA issues a recall for the same problem. Because the recall confirms the defect, the mileage offset goes back to that first visit.
The biggest mistake I see is waiting too long. The mileage offset starts at your first repair visit for the problem, so the sooner you take it in, the better. If the problem comes and goes, take it in when it happens. You can't go back to that date later.
If you get a recall notice, call a lemon law attorney right away. You may have taken the car in for the same problem before and forgotten, or there may be other recalls related to it.

Will a transmission software update fix the problem for good?
Sometimes. Many owners report that shifting problems return after an update. If yours does, go back to the dealer and make sure the visit is written up.
Does the recall fixing my car mean I have no case?
Not necessarily. Even if the recall repair fixed it, you may still have a case, and a car that's a year or more old can still qualify.
Do used cars qualify for California lemon law?
We take certified pre-owned, demo and dealer vehicles. Since the California Supreme Court's Rodriguez decision in 2024, ordinary used cars generally do not qualify.

Recall-related cases typically resolve in one to three months from your first call. Prior results do not guarantee a similar outcome.
