SERVICE BRAKES
Catastrophic brake system failure. When leaving my home in Baltimore County, MD, at approx. 10:00am on February 3rd, my vehicle started up normally. As I descended down a hill in our neighborhood the brake system failed and the vehicle would not stop. By standing on the brake pedal I slowed enough to put the vehicle in park as I entered an intersection with the main road. I have since learned this is the 3rd GMC Yukon (years 2023-2024) that has had the same brake failure in 24 hours in our community.

On January 19, 2026, Recall 25V274 was performed on my vehicle, and this was not disclosed to me when I picked up the vehicle from the dealership, Courtesy Buick GMC in Louisville, KY. I only found out when I got home and read through all the service notes. I contacted the dealer on January 19 after I got home, asking for explanation and have not heard back. The Recall Remedy failed. Since the service, symptoms of hesitation, lack of propulsion and low MPG persisted. As of Feb 1, the vehicle has suffered a transmission failure and is unsafe. The dealer told me verbally everything was fine, and in the service notes from Jan 19, they noted vehicle as 'Operating as Designed and Within Spec' despite performing safety recall work."

We had the L87 engine recall completed at 14,318 miles on Nov 20, 2025 on our 2023 Yukon XL Denali with the 6.2L engine. Engine passed all tests by dealer and we were sent on our way with 0W-40 and a new oil cap. Fast forward to Jan 21, 2026.... My wife pulled the vehicle out of driveway and noticed a deep pitched, knocking sound. She slowly started to drive down the street a bit and then the vehicle shut off and displayed a warning message on the dash (this was on a cold engine, not due to the absurd auto start/stop feature). She was able to restart and get vehicle back to the garage. We had just rolled 15,000 miles on the odometer the day before. Immediately called our dealer and had an appointment set for the next day. We were able to drive vehicle to dealer with knocking and reduced power during the drive. Dealer confirmed next day that an excessive amount of metal was found in oil and on oil filter element then supplied us with video evidence. A complete teardown has been ordered but no cause has yet been identified as of Jan 29, 2026. Service tech stated as we walked back into the dealer that "you are getting a new engine based on the amount of metal found in the oil sample". I asked about timeline for engine replacement and was told that we are looking at a month if not longer until we will get the vehicle back. We know that we are VERY fortunate to not have had the engine shutdown happen on a highway as my wife would have most certainly panicked in the situation possibly leading to a catastrophic event.

The vehicle was running perfectly fine. We pulled into a service station to fill up the gas tank, and suddenly it wouldn’t start at all. We had no choice but to have it towed to McKenzie GMC in Milton, Florida. After several days of waiting, we were told we now “need another engine.” Yes—another engine. This is completely unacceptable. This same vehicle already had its engine replaced in 2025 under recall 25V274000. It passed the PICO test, and the oil was changed to the updated 0W‑40 viscosity exactly as required. There is absolutely no reason a vehicle with a recently replaced, recall‑compliant engine should be failing like this. Something is seriously wrong with this vehicle, and it needs to be addressed immediately. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

There have been several issues for which I had to take my vehicle to the dealer. I did the engine oil recall. Then 4 months later my engine was destroyed. I’ve had several issues with oil leaks. I had an issue with my running boards a few times. And I’ve had an ongoing issue that the dealer hasn’t been able to fix - a water leak (I believe stemming from the moonroof), water gets into my vehicle, on my floorboard, and behind the dash. I’ve called to record these incidents with the dealer and taken it in several times, but they are never able to duplicate it, but they have witnessed the water leakage after the incidents (which happens during heavy downpours, and isn’t all the time because my vehicle is in the garage when I’m not at work).

My family and I received a recall notice from GM. We took the vehicle in promptly and had it "repaired" by an authorized dealer. They replaced the oil cap and placed a sticker in our owner's manual. This Christmas, instead of going to Angel Fire, New Mexico, like we do every year to visit family, we stayed home in the Rio Grande Valley. On December 28, 2025, my family decided to go holiday shopping. With kids home from college, and others off from school, I packed my wife and kids (there are six of us) into our 2023 Yukon XL to go shopping. I was driving down a busy 3 lane road with a 55 mph speed limit. By the Grace of God, I had just turned from the center lane to the right (outer) lane when our Yukon lost ALL POWER and the display read something like "Press Start/Ignition." I was utterly confused because I didn't understand what was happening. The accelerator would not work. My college daughter who was in the back asked "Dad, why did you put it in neutral?" I had not, in fact, put the vehicle in neutral. Scared with the passing traffic and sudden slowing of our Yukon, I had not realized that the vehicle had put me in neutral somehow. I tried to shift or click into the drive, but the vehicle would not respond. At some point my wife started yelling "Memo, GET OVER, GET OVER!!" I was able to coast just into the entrance of a gas station. We waited for a towing company to pick us up. Since the episode, we have now learned about this happening to other people. I can't believe that GM is letting this happen to people. We brought our vehicle in as instructed! We trusted that their "test" showed that our engine was fine. We trusted their alleged fix. I'm still in disbelief that the event occurred. I'm a grown man, and I was frightened when this occurred. I'm thankful to the Lord that one of my kids had not been driving the vehicle, or that we had been on our yearly trip to Angel Fire. Please, please, do your best to ensure that this stops happening to families.

ENGINE, FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM
Good afternoon, My 2023 GMC Yukon XL AT4 with the 6.2L L87 engine (approx. 61,000 miles) suffered a sudden and complete engine failure at highway speed while I was driving between Canton, OH, and Columbus, OH, on the expressway, returning to my home in Cincinnati. There was no warning before the engine lost all power and propulsion. I was traveling in the left lane of the interstate in moderately heavy traffic. When the engine shut down, I only had steering and braking available to me. In addition to losing all propulsion, I also lost all electronics, and there was no shoulder. The complete dashboard shut down. The only reason there was not a collision was that the traffic around me could see what was happening and slowed down themselves. I coasted on through the onramp and found a shoulder where I had three lanes of traffic on my left and two lanes on my right. Less than two months before this incident, the vehicle had been inspected and serviced by an authorized GM dealer, and no engine issues were identified. I was given no indication that the engine was at elevated risk of failure. After the breakdown, GM and the dealer determined that the failure falls under GM Safety Recall N252494002 / NHTSA Campaign 25V274000, which involves internal engine defects in the 6.2L L87 that can cause a loss of propulsion in certain GM trucks and full‑size SUVs widely used as family vehicles. GM is replacing the engine, extending the warranty, and providing a loaner, but this does not change the fact that my family was exposed to a serious safety risk, nor does it address the possibility that other owners may experience sudden loss of propulsion even after their engines “pass” dealer inspection. I am submitting this complaint so NHTSA is aware that a recalled 6.2L L87 engine, inspected shortly beforehand, still failed without warning at highway speed in a primary family‑hauler vehicle, creating a dangerous situation.

ENGINE
The engine experienced a catastrophic mechanical failure after the vehicle had been inspected by the manufacturer and certified as compliant with an engine recall. The failure occurred after the recall remedy/inspection was completed. The engine lost functionality while the vehicle was in use, resulting in loss of propulsion and the vehicle becoming disabled, requiring towing. The engine is currently available for inspection and is awaiting major powertrain repair at an authorized dealership. The sudden engine failure created a safety risk due to unexpected loss of power while driving. No collision occurred. The issue has been confirmed by an authorized dealership. The vehicle had previously been inspected by the manufacturer as part of the recall process prior to the failure. Prior to the failure, there were no known warning lamps or messages indicating an imminent catastrophic failure. The failure occurred after the vehicle had passed the recall inspection. This appears to be a post-recall remedy failure. I am concerned that the recall inspection did not adequately prevent the known defect, as the engine failed after being certified as compliant.

POWER TRAIN
I am writing to formally file a complaint regarding a serious and ongoing issue with my vehicle that has placed my safety at risk and resulted in significant inconvenience and financial burden due to General Motors’ failure to honor my warranty in a timely manner. While driving on the highway, my vehicle suddenly began losing power and displayed flashing warning messages indicating that it would not shift into gear or out of gear and that power could be lost. This created an extremely dangerous driving situation and posed a serious safety risk to me and other motorists. I brought the vehicle in for warranty service, but General Motors was unable to honor the warranty repair in a timely manner. As a result, I was without my vehicle for several months while it sat undrivable on the dealership lot. Once the vehicle was finally repaired and returned to me, the exact same transmission-related incident occurred again. Once again, I was left without the vehicle for an additional period of days. This repeat failure has severely shaken my confidence in the reliability and safety of the vehicle. When I picked up the vehicle after the subsequent repair, I was informed by a General Motors technician that the brakes and rotors were most likely pitted and damaged and would need repair or replacement because the vehicle had been sitting undrivable for such an extended period of time. I was explicitly told this damage was expected due to the prolonged inactivity caused by the unresolved warranty issue. It is critical to stress that the vehicle only sat undrivable for such a long period of time as a direct result of General Motors’ inability to honor the warranty in a timely manner. Despite this, I am now being told that the brake and rotor damage is considered a “maintenance issue,” even though a General Motors technician directly advised me that this damage would occur as a consequence of the vehicle sitting for months due to warranty delay

ELECTRICAL SYSTEM
Details of the Issue: Vehicle Model: 2023 GMC Yukon Problem Description: The battery has drained completely on three separate occasions, leaving the vehicle unable to start and in cold weather areas safety is a concern. This occurs even when all lights and accessories are turned off, and the vehicle is parked for a reasonable period of time. The vehicle has been brought to the shop three times to address this issue. During one of these visits, a module failure was identified and repaired. However, the issue has occurred again since that repair, indicating that either the original repair did not fully resolve the problem or there may be additional underlying causes. Frequency: The issue has occurred three times to date, most recently on [insert date of the most recent incident]. Service History: The vehicle has been in the shop three times for this issue, and a module failure was identified and repaired during one of these visits. Troubleshooting Steps Taken: I have ensured that no lights or accessories are left on when the vehicle is parked. The battery terminals have been inspected for corrosion, and the connections are secure. [Include any other steps you’ve taken, e.g., "The battery was tested and confirmed to be in good condition."] Request for Assistance: Given the recurring nature of this issue and the fact that it has not been fully resolved despite multiple service visits, I would like to request the following: A more in-depth diagnostic to identify any additional root causes, including potential parasitic drains, alternator performance, or software-related issues. Confirmation of whether there are any recalls, technical service bulletins (TSBs), or known issues related to the electrical system or battery for this model. Consideration for extended warranty coverage or goodwill assistance to address this issue, as it appears to be related to a manufacturing defect. Since warranty coverage is up my vehicle cost is going to increase due to repeatable issues.

VISIBILITY/WIPER
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.

While traveling on the interstate my vehicle shuttered and lost power we went to a friend’s neighborhood and the vehicle stalled when we pulled in no lights had come on until then and a knock had started. With no where to pull over I finally got the vehicle started and drove it straight to our friends house and left in on the side of the street. I had to take there vehicle home and called ONSTAR to tow it to the dealership. I have to pay for the over mileage because I was out of town when it happened.
