My engine passed the recall inspection and I was given an oil change with high grade synthetic oil. This past Saturday, March 7, 2026 as I was driving in Tampa Florida with my [XXX] son, my Yukon experienced catastrophic engine failure and I lost all propulsion control. The car went into neutral and I pulled along the side of the road safely to avoid an accident. As I put my car into park, the engine shut off completely and would not turn on again. There was no clicking sound and no attempting to turn over. I contacted roadside assistance and they sent a towing company to bring my Yukon to Century Buick GMC in Tampa Florida. The symptoms of what happened are similar to those of the recall. The dealership is replacing the engine however this is a critical safety issue as my son and I could have been severely hurt and or killed. Please investigate.

Had vehicle “serviced” at selling dealer, but they did not touch the transmission. Said they drove it around the block and it was fine. Image attached. I was then told that parts are not available and GM will not authorize swapping out the valve body. Forums posts show a lot of dissatisfaction with GM over this issue.” (NHTSA Complaint #11720657)

Power Train,Engine

Engine and cooling problems are among the most serious defects under California’s Song-Beverly Act. Owners of the 2023 GMC Yukon have reported issues including stalling, overheating, loss of power, rough idling, excessive oil consumption, and check engine lights that return after dealer repairs. With 24 NHTSA complaints on record, this defect pattern is well-documented. Owner reports include: “I just survived a terrifying incident that proves the current GM 6.2L (L87) engine “recall fix” is a dangerous myth. Living with the “Ticking Time Bomb” I bought my 2023 GMC Yukon AT4 brand new, but for the last two years, I haven’t truly “owned” it—it has owned me. Every long-distance trip with my family was filled with anxiety. I constantly worried that I’d be the next one stranded on the side of the road while my neighbors’ and friends’ 6.2L engines were seizing all around me. I traveled with fear that I’d be coming home in a rental car. The False Security of the Recall When the recall finally arrived, I thought the nightmare was over. On Sept 15, 2025, my dealer in Newburgh, NY, inspected the truck at 48,000 miles. They told me my engine “passed,” switched the oil to 0W-40, and issued me a 150,000-mile extended warranty. I realized then what I know for sure now: 0W-40 oil is a band-aid, not a cure. GM used thicker oil to “cushion” a physical manufacturing defect in the crankshaft and bearings just to avoid the multi-billion dollar cost of engine replacements. They traded my family’s safety for their bottom line. The Catastrophic Failure Last Friday, March 13, 2026, the “fix” failed. I was traveling 70 mph uphill on I-84 with my **newborn baby** and two other kids in the back. Without warning, the engine seized solid. I lost all propulsion in heavy traffic and had to fight to get my children to the shoulder. We sat in the freezing cold for over an hour while traffic flew by us. An extended warranty is worthless when your engine dies in a high-speed traffic lane with an infant in the car.” (NHTSA Complaint #11724451)

Active NHTSA Recalls — 2023 GMC Yukon

The following 4 recalls have been issued for the 2023 GMC Yukon by the NHTSA or GMC. If your vehicle is affected, the manufacturer is required to provide a free remedy. Check your VIN at NHTSA.gov/recalls.

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 Yukon:

• 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 Yukon 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 Yukon 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 Yukon Lemon Law Questions

How many repair attempts qualify my 2023 GMC Yukon 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 Yukon?

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.
