1. The engine is malfunctioning, leading to excessive oil consumption and random shutdowns. The vehicle is available for inspection at Alexander Buick GMC, Oxnard, CA, where it has been taken for repairs multiple times. 2. The engine's random shutdowns pose a significant safety risk. The vehicle can stall without warning while in motion, which could lead to accidents, especially in high-traffic situations or at high speeds. This puts the driver, passengers, and other drivers at risk. 3. Yes, the dealership Alexander Buick GMC has confirmed the excessive oil consumption and has observed the engine shutting down. However, they have not been able to determine the root cause of the shutdowns. 4. The vehicle has only been inspected by the dealership Alexander Buick GMC which is an authorized service center for the manufacturer. It has not been inspected by any other parties. 5. There were no warning lamps or messages consistently appearing before the engine shutdowns. Sometimes, the oil pressure warning light would flicker briefly before a shutdown, but not always. The excessive oil consumption was noticed approximately a year ago before the shutdowns began. Not too sure when these shutdowns started occurring.

I’m filing this complaint regarding my 2022 GMC Yukon Denali (VIN: [XXX] , MSRP ~$76,805) with an unresolved L87 engine recall. I made an appointment at my local GMC dealership on 5/8/25 specifically for the L87 recall. Upon arrival, staff only documented the Serial Data Gateway Module recall, which I hadn’t even known about. When I mentioned the 6.2L engine, I was asked if I was “sure.” I believe I was treated dismissively because I’m a woman. After pushing back, staff pulled up the bulletin, confirmed my engine needed replacement, and told me to “drive it until it blows up or there’s a fix, whichever comes first.” The L87 was only added to my receipt after I insisted—it was falsely listed as an “added operation,” though it was the reason I came in. I sent a certified letter to GM on 5/12/25 (signed for on 5/15/25) confirming the date I tendered the vehicle. Both GM and the dealer were fully aware the 60-day federal repair window had begun. It is now well past that deadline, and the L87 recall remains unresolved. Compounding the issue, the AC failed on [XXX], and the vehicle has been parked since early June due to extreme KY heat, making it unsafe to drive my children. I rely on this vehicle for daily commuting—driving ~100 miles/day for work—and it is also the only vehicle we own capable of towing our family boat, which has now sat unused all summer. I am currently paying $1,000/mo for the Yukon, $600/mo for the boat, and $200/mo for insurance—$1,800/month in preventable financial losses caused by GM’s failure to act. No repair has been offered. No loaner vehicle has been provided. No response has been received. I believe I was misled and discriminated against at the dealership, and I am now financially burdened and without a safe, reliable vehicle. This situation qualifies under the National Traffic and Motor Vehicle Safety Act for repurchase, compensation, or forced resolution. I am requesting a formal investigation and full remedy.

On 5/22/2025, I filed a complaint with NHTSA, complaint number 11662650. In the complaint, I reported issues regarding safety concerns that began around October 2023 and were shortly after reported to GMC. Some of the reported issues were concerns with oil consumption due to warning lights coming on; parking warning sensors intermittently coming on; and what appears to be suspension issues as there continues to be a knocking, cracking, and snapping noise coming from the front suspension when making a left or right turn, along with a bumping when in motion, among other issues such as Infotertainment that continues to be an issue. Recently, we took our SUV to a GMC authorized dealer since it was still under warranty and these issues continued to persist and it is getting worse. The vehicle was left around 5/28/25 and picked up on 6/17/25. However, less than a couple of weeks after, we started experiencing the same issues with the suspension as the knocking, cracking, snapping, and bumping is getting more obvious and worse, and it appears is affecting the steering and alignment of the SUV. Please update this information as there is a major concern with safety of the vehicle. Attached are some of the service records related to these issues. Should you need any additional information, please advise. Thank you.

Dropped my 2022 Yukon Denali off May 7, 2025 to Mike Reed Chevy due to failed transmission. Order was placed May 15, 2025 for a valve body part. Multiple phone calls were made without success on status of repair. I was forced to drive to the dealership for answers on June 10. I was told that due to my car being under warranty I am at the mercy of GM. The Part needed is apparently on indefinite backorder. Contacted GM to expedite part and was told it could be 3+ months before I can expect my car back. Claim number with GM is 55328239. After doing research, there is over 2000 people who are experiencing the same issue. Mike Reed Chevy nor GM offered assistance with a rental to offset the inconvenience. It was only until I demanded to speak with the service manager that I was given a rental car. As someone who manages a hospital, the delay in obtaining this part has caused significant hardship, and to date, there has been no clear timeframe provided for when the part will become available or when repairs can be completed. As a consumer, I am left without reliable transportation as the dealership has requested me to return my rental. The lack of transparency or timeline for resolution is deeply concerning. This has not only impacted my ability to fulfill daily responsibilities, but has also raised broader concerns about the availability of necessary vehicle parts and the protections in place for consumers in similar situations. I am seeing guidance or intervention from your office to help expedite this matter, whether through direct communication with the manufacturer, identifying legal remedies available under consumer protection laws, or advocating on behalf of consumers facing unreasonable delays in vehicle repairs due to supply chain issues. Any assistance or direction your office can provide would be greatly appreciated.

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.
