GMC Canyon Lemon Law

Yes. The emissions control system, including the DEF injector and SCR catalyst, is covered under the manufacturer's emissions warranty, which in California extends to 7 years or 70,000 miles. Repeated failures of the DEF system that cannot be repaired after a reasonable number of attempts can qualify your Canyon as a lemon under the Song-Beverly Act.

GMC may attempt to blame aftermarket modifications, but under the Song-Beverly Act, the manufacturer must prove that the modification directly caused the defect. If the EPS motor failure is an electrical component issue unrelated to tire size or type, the aftermarket tires would not be a valid defense. Keeping documentation that the tires meet OEM size specifications helps counter this argument.

The statute of limitations for Song-Beverly Act claims is four years from the date you knew or should have known the vehicle could not be repaired. However, it is best to file your claim while the vehicle is still under warranty or as soon as possible after the warranty expires. Delaying can make evidence harder to gather and may weaken your case.

After a buyback, the manufacturer takes possession of your Canyon and must brand the title as a lemon law buyback before reselling it. The vehicle is entered into the DMV lemon law title database and any future buyer must be notified of its history. You receive your refund minus the mileage offset and are free to purchase or lease a new vehicle.
