- Park outside and away from buildings until the repair is done.
- Book the recall appointment with any authorized Chevrolet dealer. Ask up front whether parts are available and how long the vehicle will be there.

- Write down when symptoms involving the control module happen: date, mileage, speed, weather and what you felt or heard. Photos and short videos help.
- Count the days the vehicle is at the dealer. Days out of service add up toward California's 30-day presumption.
- If the recall repair does not fix it, or the vehicle keeps going back for the same issue, talk to a lemon law attorney.

Data from NHTSA, accessed October 1, 2026. Complaints are unverified owner reports and may involve a related brakes issue rather than this exact defect; automated text matching can miss or misread some reports.

Examples of what owners have reported to NHTSA (unverified excerpts):
The brakes really seem to be lacking stopping power unloaded and especially while towing a 30' gooseneck loaded. I even have the brake controller set to 10 and it really takes awhile to stop. I have to deliberately leave even more room in front of me to make sure I can stop.
2022 Chevrolet Silverado 3500 owner, KY, NHTSA complaint 11675338, filed July 22, 2025
The braking system is very weak given the towing and load rating on the truck. Emergency stopping is at times questionable. It seems there is almost no braking from the front axle of the truck.
2022 Chevrolet Silverado 3500 owner, GA, NHTSA complaint 11683161, filed August 26, 2025
I was following a vehicle at 3-4 car lengths at 35 MPH. The vehicle in front made an aggressive stop and although I immediately saw the incident, I could not stop in time with a full panic stop by pressing the brakes hard to the floor.
2022 Chevrolet Silverado 3500 owner, FL, NHTSA complaint 11500163, filed January 4, 2023
Can recall 21V758 make my Silverado 2500 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.
A recall by itself does not make a car a lemon. Under California's Song-Beverly Consumer Warranty Act, what matters is whether a defect covered by the warranty substantially impairs the vehicle's use, value or safety, and whether the manufacturer or its dealers fixed it within a reasonable number of attempts (Civ. Code 1793.2(d)).
If the 2021-2022 Chevrolet Silverado 2500 brakes have needed more than one trip to the dealer, keep every repair order. Brake defects are treated as serious safety problems under California law.
A remedy is available. Many vehicles are fixed on the first try. If the problem returns after the recall repair, or the 2021-2022 Chevrolet Silverado 2500 has needed other repairs for the same defect, those visits count toward a lemon law claim.
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.
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 21V758
Did the recall 21V758 fix work?
Since recall 21V758 was reported on September 29, 2021, owners have filed 47 complaints with NHTSA about the brakes on these vehicles. 10 of them (21%) 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 21V758000 recall repair free?
Yes. Safety recall repairs are done free of charge at authorized dealers.
How do I know if my Silverado 2500 is part of recall 21V758000?
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.
