- Write down when symptoms involving the automatic transmission happen: date, mileage, speed, weather and what you felt or heard. Photos and short videos help.

Here is what some owners told NHTSA, in their own words (excerpts, unverified):
Since I purchased my 2022 Cadillac XT5 which was on 5-9-26, I have had issues with the performance of the transmission. Every time I slow down, the car down shifts very abruptly and roughly until the car comes to a complete stop. I also experience rough gear shifts when accelerating as well.
2022 Cadillac XT5 owner, TX, NHTSA complaint 11760357, filed August 28, 2026
The contact owns a 2023 Chevrolet Blazer. The contact stated while driving at an undisclosed speed, the vehicle shuddered, and the transmission was difficult to shift into gear. There was no warning light illuminated. The vehicle was taken to an independent mechanic and was diagnosed with transmission failure.

Can recall 23V172 make my XT6 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 23V172000 does not automatically make your XT6 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 2023 Cadillac XT6: 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.
This campaign follows an earlier recall for the same issue. A second recall can mean the first remedy failed, and repeated repair attempts on the same defect are the core of most lemon law claims.
Earlier campaigns on these vehicles involving the same component: 21V817000.
California law presumes a reasonable number of attempts has been made if, within 18 months or 18,000 miles of delivery, the same problem was repaired two or more times for a defect likely to cause death or serious injury, four or more times for any covered defect, or the vehicle was out of service for repairs more than 30 days in total (Civ. Code 1793.22(b)). Some of these require written notice to the manufacturer. A claim can still succeed outside that window.
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.

Frequently asked questions about recall 23V172
Did the recall 23V172 fix work?
Since recall 23V172 was reported on March 16, 2023, owners have filed 59 complaints with NHTSA about the transmission on these vehicles. 7 of them (12%) describe the same problem happening more than once or coming back after a repair attempt. If your vehicle still has the problem after the recall repair, go back to the dealer, get a repair order, and talk to a lemon law attorney.
Is the 23V172000 recall repair free?
Yes. Safety recall repairs are done free of charge at authorized dealers.
How do I know if my XT6 is part of recall 23V172000?
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.
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 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.
