How long state lemon laws protect a Chevrolet
With 3 years / 36,000 miles of basic coverage, your Chevrolet’s warranty usually outlasts its lemon law window. A two-year state closes the window with 1 year of warranty to go; a one-year state, with 2 years. Repairs in that gap are free, but they rarely count toward a buyback.
| State window | Jurisdictions | Chevrolet basic warranty at that point |
|---|---|---|
| The warranty term | New Hampshire, Vermont | Window lasts the full 3 years / 36,000 miles |
| Three years | 1 | about the same time the basic warranty ends |
| Two years | 21 | 1 year of basic coverage still left |
| 18 months | 3 | 18 months of basic coverage still left |
| One year | 23 | 2 years of basic coverage still left |
Many windows also stop at 12,000 to 24,000 miles, long before the 36,000-mile limit on a Chevrolet warranty. Find your state’s exact rule in our state guides, or check your Chevrolet repair history against your state’s window.
Chevrolet’s dispute program
BBB National Programs lists Chevrolet as a national participant in BBB AUTO LINE, and Buick, GMC and Cadillac are on its participant list too. Certain warranty and lemon law disputes are accepted from every state, subject to other eligibility rules in GM’s program summary.
BBB AUTO LINE is free and does not need a lawyer. Call 1-800-955-5100. Chevrolet’s warranty booklet also explains GM’s customer assistance steps, which usually come first.
Buick, GMC and Cadillac owners
This guide uses Chevrolet’s published terms, but the lemon law side is the same for every GM brand. Buick, GMC and Cadillac each appear on BBB National Programs’ list of BBB AUTO LINE participants, so the same free dispute route is open to you. Check that brand’s own warranty booklet for coverage lengths, and its BBB page for the program summary.
Two practical points apply across GM. First, warranties that are still active move with the vehicle when it is sold, which can matter in states that protect later owners during the warranty. Second, GM offers courtesy transportation during warranty repairs, so ask for it, but make sure the repair order still records each day the vehicle was out of service. Those days are the evidence for a days-out-of-service test.

Things Chevrolet owners should know
- Chevrolet offers courtesy transportation during warranty repairs. Ask for it, and make sure the repair order still shows every day the vehicle was in the shop.
- Because GM warranties transfer, a used Chevrolet bought inside the warranty may still qualify in states that cover later owners during the warranty.
- Check open recalls on your VIN. If a recall repair targets your defect, keep that repair order with the rest.
What to do if your Chevrolet is a lemon
- Keep every repair order from the Chevrolet dealer, including the days you used courtesy transportation, and make sure each lists your complaint and mileage.
- Call Chevrolet customer service (800-222-1020) and ask for a case number.
- Send written notice using the address in your Limited Warranty and Owner Assistance booklet or the one your state requires; our letter generator can draft it.
- Start a BBB AUTO LINE claim if your state or GM’s program summary calls for it, or if you want a free decision first.
- File in your state’s program or court before your deadline, and bring the full repair history.
