Owner reports include: “We purchased a 2023 GMC Acadia AT4 new in October 2023. There is currently a little over 19,000 miles on the AT4. As of today November 13, 2024 the SUV has been to Blaise Alexanders, for at 3 times with same issues. Between the speeds of 50-65 there is a shudder, which in August 2024, the Chevy garage changed the fluid However, You can now feel this at any speed through out a trip. The SUV was return to the shop for increasingly worse shudder between 50-65 and a new issue of “hunting” between 25-35. There are times that the SUV does not want to propel forward (like the AT4 cannot get out of its own way) Also, when making a sharp right turn followed by an immediate left turn, onto uneven surface, the AT4 acts as though it is confused as to what gear it should be. The garage was then notified that I know have whining sound. At one point the garage had the AT4 for a week, the general manage drove it, did not feel anything. I then returned, took him for drive and he felt it. Left the car for him to take one of the “transmission” repair individuals out on a drive with the scan tool hooked up. Results of that test drive—“the car did it once, slightly but it was not picked up on the scan tool.” Troy, from the service desk informed us they called GM to have their traveling engineer come look at the AT4 in a few day. GM’s representative stop at the garage, DID NOT look at the car or speak to us, but has Troy tell us to keep driving the car. We are now in November and unfortunately, I got a little behind on bugging them due to the loss of my brother, father and step -father. But then again they have made no attempt at resolving this issue. This is frustrating. We are asking for any assistance that you can provide. I find it hard to believe that we are the only individuals that are experiencing these issues. I love my car. Why did they change the fluid if nothing was wrong the first time?? It has progressively been getting worse and winter is coming……” (NHTSA Complaint #11625026)

The 2023 GMC Acadia has generated 4 NHTSA complaints for this defect category. If your vehicle has experienced recurring issues in this area that the dealer has been unable to repair after multiple attempts, you may have a qualifying lemon law claim under California’s Song-Beverly Consumer Warranty Act. Owner reports include: “Since late 2023/early 2024, I started to notice that my liftgate was open, while the Acadia, a lease with less than 15K miles, was parked in the driveway, off. At first, I thought it was a mistake on our part, that we had accidentally hit the button on the remote to open it or had forgotten it open. As time went on, the incidences continued and I realized it was happening on its own, while the car was off! When the Acadia was at the dealership this fall for a warrant repair (a pump that GM knew was problematic but only has alerts out about for now), I mentioned the liftgate. Thankfully, the problem happened at the dealership too so workers could witness it. It’s a major safety issue and a public safety issue. When the pump repair was occurring, I got a text from the dealership that the problem with the liftgate was my fault, that how I clean the inside of the car had affected the mechanics and that I would be on the hook for over $300 in repairs. I had no way to prove otherwise and opted to instead disable the open function using the dial on the driver door set to off and it has not opened. Fast forward to last week and GM has a recall on GMC and other pickups where this kind of issue appears to happening to tailgates and it instantly felt similar. I believe GMC Acadia’s have the same faulty wiring and I should not be on the hook for this repair but GM should fix the problem.” (NHTSA Complaint #11629624)

California Lemon Law — Song-Beverly Act

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 2023 GMC Acadia:

• 4+ repair attempts for the same non-safety defect without resolution
• 2+ repair attempts for a defect likely to cause death or serious bodily injury
• 30+ calendar days out of service for warranty repairs (cumulative, not consecutive)

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.

What You Can Recover

If your 2023 GMC Acadia qualifies as a lemon under California law, GMC may be legally required to:

• Repurchase your vehicle — Full refund of your down payment, all monthly payments, registration fees, and incidental costs (towing, rentals), minus a mileage offset for miles driven before the first repair attempt
• Replace your vehicle — Provide a new, comparable vehicle at no cost to you
• Pay your attorney’s fees — Under § 1794(d), GMC pays all legal fees if you prevail
• Civil penalty up to 2x damages — If GMC willfully violated the Act, courts may award double the actual damages

Steps to Protect Your 2023 GMC Acadia Claim

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.

2023 GMC Acadia Lemon Law Questions

How many repair attempts qualify my 2023 GMC Acadia as a lemon?

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.

Does GMC pay my attorney fees?

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.

Can I file a lemon law claim without an active recall?

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.

What is the time limit to file a lemon law claim for my 2023 GMC Acadia?

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.
