Chevrolet Silverado HD Lemon Law

General Motors recalled roughly 462,000 diesel trucks and SUVs — including Silverado 2500HD and 3500HD models with the 6.6L L5P Duramax and Allison-branded 10-speed transmission — because a transmission control valve can wear and lose pressure over time (NHTSA campaign 24V797). As it fails, shifting becomes harsh, and the rear wheels can lock up while the truck is moving, a serious crash risk. The remedy is control-module software that limits the transmission to fifth gear once excess wear is detected. GM has separately had to replace entire transmissions on some 2024 HD trucks built with an incorrect caged piston bearing.

Silverado HD owners also report other recurring issues: rough or delayed shifting, Duramax diesel emissions and DEF (diesel exhaust fluid) system faults and warnings, fuel-injector problems, and electrical or infotainment glitches. When a software 'fix' masks a shift problem instead of curing it, or a diesel keeps throwing the same emissions codes after repairs, that pattern is exactly what California's Lemon Law is meant to address.

The Lemon Law covers vehicles under the manufacturer's original warranty, and it can protect business and commercial trucks too: a business with five or fewer vehicles registered in California qualifies for a truck under 10,000 pounds. If your Silverado HD has had a reasonable number of failed repairs or long shop stays for the same defect, Chevrolet may owe you a buyback, a replacement, or a cash settlement — with your attorney fees paid by Chevrolet.

A recall is not automatically a lemon — it's the manufacturer acknowledging a defect and offering a free repair. California's Lemon Law (the Song-Beverly Act) comes into play when a substantial defect can't be fixed after a reasonable number of attempts, or when your Silverado HD has been out of service for 30 or more cumulative days.

If your Chevrolet Silverado HD qualifies, you may be entitled to a buyback (a refund of what you've paid, minus a mileage offset), a replacement vehicle, or a cash-and-keep settlement — and Chevrolet pays your attorney fees on a successful claim, so pursuing your case costs you nothing out of pocket.
