2023 GMC Yukon Xl

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.

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. Regards, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(

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.

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

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.

2023 Gmc Yukon XL SLT 5.3 Liter V8 engine As i was crusing on hiway my engine gave up lost of power knocking noise and check engine light appeared on dash it was a very serious matter when you are on hiway and engine fails on you ive gotte the car diagnosed it had known issue like the rest of GM trucks and suv Lifter failure/camshaft/push rods complete engine had to be either replace or professional rebuilt. This vehicle brand new is almost $100k vehicle which shouldnt have had this issue under 2 years of ownership and paying out of my own pocket. I urge NHTSA to take this matter in to consideration and have the GM 5.3 liter V8 engine under recall just like they have with the 6.2 liter V8 engine they have the same problem with the lifters, camshaft,pushrod failure. Thank you
