GMC Sierra EV Lemon Law

GMC Sierra EV owners most often report charging and software problems: sessions that fail to start or drop mid-charge on both home and DC fast chargers, slower-than-expected charging, inaccurate range and state-of-charge readings, and infotainment or instrument-cluster screens that freeze, go dark, or reboot. Because so much of the truck is controlled by software, a single bad update or module can trigger a cascade of warnings and features that stop working.

GM has also issued a software recall on the Sierra EV: after an electronic stability control malfunction, the dashboard warning light might not illuminate on the next start, leaving the driver unaware the system needs attention. The remedy is a software update, delivered at the dealer or over the air. When software updates don't resolve a problem — or introduce new ones — owners can be left cycling through repeat service visits.

California's Lemon Law can apply when a substantial defect isn't fixed after a reasonable number of repair attempts, or when the vehicle is out of service for an extended period, while under the manufacturer's warranty — and electric vehicles are fully covered. A recall or a pending software fix does not automatically make a truck a lemon, and you do not need a recall to qualify; persistent charging or software failures the dealer can't resolve can be enough. If your Sierra EV qualifies, you may be entitled to a buyback, replacement, or cash settlement, with GM paying your attorney fees.

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 Sierra EV has been out of service for 30 or more cumulative days.

If your GMC Sierra EV 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 GMC pays your attorney fees on a successful claim, so pursuing your case costs you nothing out of pocket.
