General Motors Lemon Law attorney help for defective vehicles and warranty claims
General Motors is America’s second-largest automaker, moving about 2.5 million vehicles per year across four brands—Chevrolet, GMC, Buick, and Cadillac, and any of those vehicles can trigger a General Motors lemon law claim when the same defect keeps showing up at the dealer, from Silverado transmission shudder to Bolt battery recall waits to Escalade air suspension failures to Hummer EV Ultium software bugs.
The Lemon Reps have recovered $617,100 across 176 GM-group cases — an average of roughly $3,500 per case, with Cadillac and GMC Denali recoveries pushing substantially higher as part of our broader $3.2M+ recovered across 1,500+ cases nationwide, and we handle claims across all four GM brands in every state.
William C. Durant founded General Motors in 1908 in Flint, Michigan, stitching the company together through acquisitions of Buick, Oldsmobile, Cadillac, and Oakland (later Pontiac) before losing control twice and dying in obscurity in 1947. GM declared bankruptcy in 2009 during the financial crisis and re-emerged as “New GM” after a government-backed restructuring, which discharged many legacy liabilities but left General Motors’ lemon law obligations for post-reorganization vehicles fully intact. The four North American brands today—Chevrolet (mainstream), GMC (trucks and SUVs), Buick (semi-premium), and Cadillac (luxury)—all share the same platforms, which is why the same L87 engine failure or 8-speed transmission defect shows up across multiple brands at the same time.
When a GM vehicle cannot stay out of the shop, both the state lemon law and the federal Magnuson-Moss Warranty Act apply identically across all four brands; see our lemon law overview for the framework.
Your GM vehicle likely qualifies when the same defect has been repaired 2 or more times for a safety issue (3 to 4 for non-safety issues), it has been out of service 30 or more cumulative days, or the defect substantially impairs use, value, or safety. Common triggers across all four GM brands include:
Most state laws run 18 to 24 months or 18,000 to 24,000 miles from delivery; Magnuson-Moss extends to 4 years from breach. Keep every repair order, photograph warning lights, track odometer readings, and save correspondence with General Motors Customer Assistance.

Here is the GM differentiator: one buyback pipeline serves four brands. GM processes all Chevy, GMC, Buick, and Cadillac claims through its Customer Assistance Center and a dedicated Reacquired Vehicle Team based in Warren, Michigan. Each brand has its own customer service line:
The buyback processing is centralized in Warren regardless of which brand you bought. GM participates in BBB AUTO LINE as the informal dispute option (binding on GM, not on you), and opening offers arrive as extended powertrain warranties, free service contracts, or trade-in credits well below a statutory buyback.
A typical General Motors buyback funds within 30 to 90 days from the signed settlement. Timeline depends on case complexity:
Clear-cut cases (Bolt battery waits, repeated L87 failures, multiple 8-speed repairs)
Standard contested cases
Ultium EV Software disputes
CPO coverage disputes
Reacquired Vehicle Services handles the title, the vehicle surrender at a designated inspection location, and the check release in coordination with your lienholder.

No! You pay nothing out of pocket. If your case qualifies, the manufacturer covers all legal costs—so there’s no risk to you.
Many settlements are based on the purchase price minus a mileage offset, plus incidentals. Vehicle value and the repair pattern matter most. Higher-value trucks and luxury SUVs can produce higher recoveries.
GM lemon law settlements can take two forms. The first is a class action settlement where GM agrees to compensate a large group of affected consumers, typically involving a specific defect across multiple model years. The second is an individual settlement negotiated directly between your attorney and GM on your behalf. Individual GM lemon law settlements generally result in higher compensation than class action payouts because they are tailored to the specific losses you experienced.
GM processes all brand buybacks through its Reacquired Vehicle Team at the Warren, Michigan corporate campus, with brand-specific customer service numbers routing you to the same team. An attorney sends formal demand letters directly to GM’s legal department, which moves the case past the first-line customer service loop.
It may. The GM ignition switch defect affected millions of Chevrolet, Pontiac, and Saturn vehicles and is one of the most significant automotive safety scandals in U.S. history. If your vehicle was part of the recall and you experienced defects related to the ignition switch, you may still have grounds for a GM Lemon Law claim depending on your state’s laws and the timing of your repair attempts. Even if your vehicle was repaired under the recall, if the underlying defect or related issues persist, a separate GM Lemon Law claim may be appropriate.
