Here is what some owners told NHTSA, in their own words (excerpts, unverified):
Visibility / Defogging / Defrosting issues are main safety concerns. Every winter for the last 3 years, the heater fails and blows only cold air. This is intermittent throughout the year, but recurring. With cold-weather driving conditions, it creates an unsafe driving experience when windshield and windows can't defog or defrost properly.

Same situation occurred twice. I was in the car at a red light. Car had been stopped for about a minute. Was on a slight decline, engine brake was engaged to hold car in position. Car was stationary completely.

Can recall 22V771 make my Hummer EV Pickup 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)).
High-voltage battery and drive system defects in EVs and hybrids can mean reduced range, charging faults, loss of drive power or a fire risk. These repairs often need parts on backorder, so days out of service add up quickly.
A remedy is available. Many vehicles are fixed on the first try. If the problem returns after the recall repair, or the 2022-2023 GMC Hummer EV Pickup 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 Hummer EV Pickup 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.
A recall with no fix can support a buyback on its own.
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.
Recall repairs depend on parts. Owners can wait days, weeks or months, usually about one to three months in our cases, and those days count toward California's 30-day out-of-service rule.
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 22V771
Is the 22V771000 recall repair free?
Safety recall repairs are normally free at authorized dealers. Check the owner letter or ask the dealer to confirm before work begins.
When will owners be notified?
According to NHTSA, owner notification letters were or are scheduled to be mailed April 13, 2023.
How do I know if my Hummer EV Pickup is part of recall 22V771000?
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.
Can a battery recall reduce my EV's range?
Some battery recalls limit the state of charge or range until a module or pack is replaced. Check your owner letter for any interim limits, and keep notes if range or charging changes after the repair.
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.
