While driving through rain on a long car trip, the wipers suddenly became completely inoperable. We could not see and were on a highway causing a serious safety issue. We had to drive very carefully off the next exit ramp. Tried turning on and off the car, no luck. Tried toggling the rain sense on the display and finally wipers came back on. About 20 miles down the road the same thing happened. Wipers became inoperable. We had to exit highway 4 times to try to wait and toggle for wipers to come back on. Immediately had it checked my a mechanic at our destination and he could find no cause for the incident. Our best guess is there is some computer glitch that needs to be fixed and I predict there will be a recall. Hopefully not before a disaster.

Classic Buick GMC (Classic Elite Buick GMC – Katy) Filed by: [XXX] [XXX] [XXX] Phone: [XXX] Email: [XXX] Date: November 23, 2025 Texas Attorney General – Consumer Protection Division RE: SUMMARY COMPLAINT – Vehicle Misrepresentation, Unauthorized Charges, Financing Fraud & Warranty Violations Dear Attorney General, I am filing this complaint against Classic Buick GMC (Classic Elite Buick GMC) located at [XXX] , for multiple violations of Texas consumer-protection laws during the sale and follow-up service of a vehicle I purchased in March 2024. Summary of Violations 1. Misrepresentation of Vehicle Model Year I was sold a 2023 GMC Yukon Denali that the dealership falsely represented as a brand-new 2024 model, including on the key-tag. This violates Texas Occupations Code §2301.351(a) and DTPA §17.46(b)(5), (7), (24). 2. Unauthorized Add-Ons & Hidden Charges The dealership added $8,000 in accessories and $26,000 in warranty products without my consent. This violates DTPA §17.46(b)(12). 3. Financing Fraud I was promised 1% financing, but the dealership charged a significantly higher rate at closing without disclosure. This violates the Truth in Lending Act (TILA). 4. Warranty Refusal & Pre-Existing Damage Although the vehicle had defects and mechanical issues at delivery, the dealership refused to repair them under warranty unless I paid. This violates the Magnuson-Moss Warranty Act. 5. Failure to Provide Required Documentation The dealership refused to provide complete purchase documents, violating Texas Administrative Code §215.142. 6. Pattern of Evasion I personally visited the dealership three times, yet management refused to correct any misconduct. 7. Unsafe Vehicle Retained at Dealership The Yukon remains at the dealership due to mechanical/electrical defects. I refused to pick it up because the vehicle is unsafe and not as represented.

The contact owns a 2023 GMC Yukon XL. The contact stated that while driving approximately 25 MPH and depressing the brake pedal, the vehicle failed to respond. Several unknown warning lights were illuminated, and the message "You Have no Brakes - Do Not Drive Over 40 MPH" was displayed. The contact allowed the vehicle to roll to a stop. The contact turned off and restarted the vehicle, but the failure persisted. The contact parked the vehicle. The contact stated that the failure had not caused an accident because the contact was driving early in the morning and there was less traffic on the road. The contact stated that her husband started the vehicle later in the day, and the warning lights were off. The vehicle was driven to the dealer to be diagnosed. The dealer diagnosed the vehicle and informed the contact that several DTCs were retrieved, including a DTC for brake failure; however, the flow chart from the manufacturer instructed to first replace the battery and then reset the codes. The dealer replaced the battery, reset the codes and test-drove the vehicle. The vehicle was repaired and returned to the contact. The manufacturer was notified of the failure and supported the dealer's assessment. The failure mileage was approximately 70,000.

The vehicle underwent a recall inspection on September 8, but on October 2, the vehicle still experienced a serious engine failure. The vehicle was undrivable, and the dealer inspected it and opened a TCA case. However, General Motors stated that it had passed the recall test and was not covered under special warranty, and asked me to pay $5,000 for vehicle repairs. I believe this is an engine malfunction related to the recall, and the manufacturer should replace the engine for me free of charge and refund my 5,000 .

The vehicle has experienced numerous losses of power, it has nearly stalled during normal operation, there is a horrible knocking noise coming from the engine. I have had the vehicle into the dealership who state they are unable to recreate the issue, and since the vehicle has been turned off the recorder shows noting either. They have performed an inspection and changed the oil, but the vehicle still has the issue. It knocks and shudders like it's cold, it comes very close to stalling and then seems to recover, this has happend twice while making left hand turns, it has completly lost power even while depressing the gas, but again they indicate they can't recreate it, so there is nothing they can do. I am scared for my safety, and that of the child I drive daily. There have been several instances in the last few months.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation. ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.
