If your GMC truck or SUV keeps going back to the dealership for the same defect, you may have rights under the California Lemon Law. GMC’s full-size trucks and SUVs — including the Sierra, Yukon, and Canyon — have been the subject of major federal recalls and ongoing defect investigations. When a manufacturer cannot repair a substantial warranty defect after a reasonable number of attempts, California law may require it to buy the vehicle back or replace it.

Does Your GMC Qualify Under the California Lemon Law?
The California Lemon Law — the Song-Beverly Consumer Warranty Act — protects owners and lessees of new and certain used vehicles still covered by a manufacturer’s warranty. Your GMC may qualify if:
- It was bought or leased in California with a manufacturer’s warranty
- It has a substantial defect that affects its use, value, or safety
- The dealer has made a reasonable number of repair attempts and the problem remains
Generally, a “reasonable number of attempts” can mean two or more tries for a serious safety defect, four or more for the same recurring problem, or 30 or more days out of service for warranty repairs. These are guidelines, not strict limits. Not sure where you stand? Our Do I Qualify Under the Lemon Law page walks through the criteria, and our California Lemon Law Process page explains what happens next.
Common GMC Problems That May Lead to a Lemon Law Claim
GMC shares engines and transmissions with the wider General Motors lineup, so many GMC defects also appear in Chevrolet and Cadillac models — see our General Motors Lemon Law page for more. The issues below are documented in federal recall filings, NHTSA investigations, and active litigation.
6.2L V8 (L87) Engine Failure
In April 2025, General Motors recalled approximately 597,630 U.S. vehicles equipped with the 6.2L V8 “L87” engine under NHTSA campaign 25V274. According to NHTSA filings, manufacturing defects in the connecting rods and crankshaft can cause the engine to fail and lose power while driving, raising the risk of a crash. The recall covers 2021–2024 model-year vehicles, including the GMC Sierra 1500, Yukon, and Yukon XL, alongside several Chevrolet and Cadillac models.
The remedy involves an inspection: engines that pass receive higher-viscosity oil and a new filter, while engines that fail are replaced. Into late 2025 and 2026, NHTSA opened a further engineering analysis after owners reported continued engine failures even after the recall repair — so this issue remains active. If your GMC has had repeated engine problems, stalling, or a replacement that did not solve the issue, those repair records may support a lemon law claim.
8-Speed Transmission Shudder
Many 2015–2019 GMC Sierra, Yukon, Yukon XL, and Canyon models use GM’s 8-speed (8L45 or 8L90) automatic transmission, which owners have widely reported shuddering, shaking, jerking, or “hard shifting.” A nationwide class action over this defect was decertified by a federal appeals court in June 2025, meaning affected owners generally now have to pursue their own individual claims rather than rely on a single class. For California owners, that makes an individual lemon law claim — backed by your own repair history — especially important.
10-Speed Transmission Recall
In February 2026, GM issued a recall covering certain 2020–2022 Chevrolet Silverado and GMC Sierra trucks — part of a larger action affecting more than 460,000 GM vehicles — tied to a transmission control issue that can cause harsh shifts or a momentary loss of drive. A separate NHTSA investigation into 10-speed hesitation and shuddering remains open.
What Your GMC Lemon Law Buyback Could Include
If your GMC qualifies, a buyback (also called a repurchase) generally requires the manufacturer to refund:
- Your down payment and monthly payments
- The remaining loan payoff
- Taxes, license, and registration fees
- Incidental costs such as towing and rental cars
The refund is reduced only by a statutory “mileage offset” for the miles you drove before your first repair visit. Our California Lemon Law Buyback Guide explains exactly how the amount is calculated. In some cases, you may also be entitled to a civil penalty if the manufacturer acted willfully. Leased your GMC? You may still qualify — see our Lemon Law for Leased Vehicles page. Bought certified pre-owned? Review our Certified Pre-Owned page.

GMC Lemon Law FAQ
How many repair attempts before my GMC qualifies?
There’s no single magic number, but California generally looks at two or more attempts for a serious safety defect, four or more for the same recurring issue, or 30+ days out of service. Strong claims can sometimes be built outside those exact figures.
My GMC engine was replaced under the recall. Can I still file?
Possibly. A recall repair and a lemon law claim are separate things. If your engine continued to have problems, or the vehicle was out of service for an extended time, your repair records may still support a claim.
Does GMC have to pay my attorney fees?
In successful California lemon law cases, the manufacturer is generally required to pay reasonable attorney fees and costs — which is why most clients pay nothing upfront.
What if my GMC is leased or financed?
Leased and financed vehicles can both qualify. The refund is handled a little differently, but you may still recover your payments and costs.
How long does a GMC lemon law claim take?
Many cases resolve within a few months, though timelines vary depending on the manufacturer’s response and the complexity of the defect.
