A few excerpts from owner complaints filed with NHTSA (unverified, lightly trimmed):

Can recall 22V642 make my 3500 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 22V642000 does not automatically make your 3500 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))?
Engine defects can mean stalling, loss of power, oil consumption or overheating. When the same engine complaint brings the 2022 Ram 3500 back to the dealer more than once, that history matters under California's lemon law.
A remedy is available. Many vehicles are fixed on the first try. If the problem returns after the recall repair, or the 2022 Ram 3500 has needed other repairs for the same defect, those visits count toward a lemon law claim.
For the first 18 months or 18,000 miles, California presumes the manufacturer had enough chances if the 3500 went in two or more times for a defect likely to cause death or serious injury, four or more times for the same defect, or spent more than 30 days in the shop (Civ. Code 1793.22(b)). Direct notice to the manufacturer is required for some of these. The presumption is a shortcut, not the only path to 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.

How do I know if my 3500 is part of recall 22V642000?
Enter your 17-character VIN in NHTSA's recall lookup at nhtsa.gov/recalls, or call a dealer. The VIN is on your registration, insurance card and the lower corner of the windshield.
Does a recall mean my car is a lemon?
Not on its own. A lemon law claim depends on whether a covered defect keeps coming back or keeps the vehicle out of service. A recall repair that fails, or repeat visits for the same problem, can support a claim.
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.
How long does a recall lemon law case take?
Recall-related cases typically resolve in one to three months from your first call. Prior results do not guarantee a similar outcome.
What does a lemon law attorney cost?
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.
