Examples of what owners have reported to NHTSA (unverified excerpts):

GM does not install TPMS devices in spare tires. I had a flat tire in snowy conditions 100+ miles from the nearest place for assistance. After putting on the spare tire the DIC (driver information center) displayed no air in tire. That’s because a TPMS doesn’t exist in spare tires.

Can recall 24V797 make my Silverado 1500 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.

Owners often ask whether this valves and valve body recall means their Silverado 1500 qualifies as a lemon. Not by itself. Song-Beverly looks at whether a defect covered by the warranty substantially impairs use, value or safety and was not fixed after a reasonable number of repair attempts (Civ. Code 1793.2(d)).

A transmission defect affects the core job of the 2021-2022 Chevrolet Silverado 1500: 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.

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 1500 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 Silverado 1500 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.
