Powertrain and transmission defects directly impair the vehicle’s core function and are generally considered substantial defects under California lemon law. Owners of the 2020 GMC Canyon have reported harsh shifting, shuddering, slipping, and transmission warning lights. 8 NHTSA complaints have been submitted for this defect category. Owner reports include: “The main issue is the transmission… It shudders. Now I have to change the oil every 10K miles on it, or it will start shuddering again. It first started when the truck had 50K or a little more miles in it. The issue was resolved, I thought… Then it did it again at 69K (Just out of the warranty). I called the dealership and they stated I had to pay if I wanted an oil change, and they could not do an oil flush even if I paid for it. So I said OK, I will take it to a mechanic, and I did and “fixed” the problem. I used the oil GM recommended and the shuddering stopped. BUT then, another 10K miles and it starts again. I have changed the oil a lot of times… It now has 128K miles in it, and this last time, I had to change the oil at 9k miles because of the shuddering… What will be next? I will have to change it at 5K miles, just like the motor oil? It is sad to see all these people having the same issue as I do, and GM does not do anything about it. I’ve done a lot of research… There is a guy that fixes the issue eliminating a specific valve, in the transmission, and updating the other ones with higher quality valves they make to fix the problem. I’m sure it would cost GM some money, but these trucks are expensive, you know? It is sad that no one is trying to help consumers when companies sale these cars and trucks to the public for a very high price and they do not take care of the mistakes they make when producing them. Please help us making GM fix this transmission issues. It is not fare for us consumers to be having trouble with new vehicles. Thank you for your time.” (NHTSA Complaint #11711123)

As of the date of this review, no active recalls have been issued specifically for the 2020 GMC Canyon. Recall status can change at any time.

California’s Song-Beverly Consumer Warranty Act (Cal. Civ. Code §§ 1790–1795.8) is one of the strongest lemon laws in the United States. It protects buyers and lessees of new and certified pre-owned vehicles that develop substantial defects the manufacturer cannot repair after a reasonable number of attempts.
Under Cal. Civ. Code § 1793.22, a lemon law presumption is triggered when any of the following apply to your 2020 GMC Canyon:
Once the presumption is triggered, the burden shifts to GMC to prove the vehicle is not a lemon. Under Cal. Civ. Code § 1794(d), GMC must pay your attorney’s fees if you prevail — meaning qualified representation costs you nothing out of pocket.
If your 2020 GMC Canyon qualifies as a lemon under California law, GMC may be legally required to:
Step 1: Document every repair visit. Keep all repair orders, work orders, and dealer invoices. Each visit counts as a repair attempt, even if the dealer says nothing is wrong.
Step 2: Keep returning for repairs. You must give GMC a reasonable opportunity to fix the defect. Visit different authorized GMC dealers if needed and ask for written documentation of each visit.
Step 3: Contact a California lemon law attorney. Once you believe the threshold has been met — 4 attempts for non-safety defects, 2 for safety defects, or 30 days out of service — contact an attorney for a free case evaluation. Under § 1794(d), GMC pays your fees if you win.
Step 4: Send a demand letter. Your attorney will send GMC a formal demand letter. Most California lemon law cases resolve through negotiation without going to trial.
Under Cal. Civ. Code § 1793.22, four or more repair attempts for the same non-safety defect, or two attempts for a safety-related defect, triggers the lemon law presumption. Additionally, 30 or more cumulative days out of service qualifies regardless of the number of repair attempts.
Yes. Under Cal. Civ. Code § 1794(d), GMC is required to pay your reasonable attorney’s fees and court costs if you prevail in a lemon law claim. This means qualified lemon law representation is free to you if your case succeeds.
Yes. A recall is not required to file a lemon law claim. The Song-Beverly Act covers any substantial defect that impairs the use, value, or safety of the vehicle that the manufacturer cannot repair after a reasonable number of attempts. NHTSA complaints support the claim by establishing a pattern, but are not a prerequisite.
California lemon law claims are generally subject to a four-year statute of limitations from the date you discovered or should have discovered the defect. However, you must still be within the manufacturer’s original warranty period when the defect first appears. Contact an attorney promptly to preserve your rights.
