A few excerpts from owner complaints filed with NHTSA (unverified, lightly trimmed):
On December 13, 2025, my vehicle (2021 Mazda CX-30) was serviced at a Valvoline Instant Oil Change location. During service, the technician stated he was checking tire pressure and asked whether 36 PSI was acceptable. I agreed. When I pulled out of the bay, the tire pressure warning light remained on and showed 29 PSI.
2021 Mazda CX-30 owner, NY, NHTSA complaint 11705780, filed December 18, 2025
At 31,000 miles the control arm lower ball joints are torn on both lower. They must be replaced. This is a safety hazard. This should not be an issue with low mileage on this car.
2021 Mazda MAZDA3 owner, CA, NHTSA complaint 11695896, filed October 27, 2025
For the past 7 months (since July 2023) the passenger rear tire keeps loosing air pressure about every two weeks requiring more air. It always drops to 10 points below the other tires. The tires have been rotated twice so it is not a problem with the tire.

Can recall 21V101 make my MAZDA3 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 21V101000 does not automatically make your MAZDA3 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))?
If a suspension or wheel problem on the 2021 Mazda MAZDA3 returns after the recall work, keep the repair orders. Repeat visits for the same defect are what 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.
For the first 18 months or 18,000 miles, California presumes the manufacturer had enough chances if the MAZDA3 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.
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 MAZDA3 is part of recall 21V101000?
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.
What should I keep for a possible lemon law claim?
Keep every repair order, the recall owner letter, your purchase or lease contract, and notes on dates, mileage and symptoms. Make sure each dealer visit is written up, even when the dealer says it cannot find a problem.
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.
