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.

Acceleration failing. Knocking of motor, winding sound, a huge clicking sound when accelerating, and engine burning very excessively. We have 4 children and its very unsettling to say the least on a 100,000 vehicle we paid for. I hope and pray you include our vin number with the 6.2 recall as the dealer is well aware of this problem long before the current recall. It's very unfortunate that our vin wasn't part of this very serious safety issue. Thank you

Driving down the expressway at 65MPH, and the Vehicle completely stops, almost causing a collision. After researching the problem at the GMC Dealer, it appears that the entire engine has internally failed. Apparently it was a Complete Engine Failure.

ENGINE
I received an official safety recall notice from GM (Recall Number N252494000) for my 2021 GMC Yukon due to a defect in the engine's connecting rod or crankshaft components. GM stated that this defect can cause engine failure and loss of propulsion, which significantly increases the risk of a crash. The notice also confirmed that parts to fix the issue are currently unavailable and provided no timeline for resolution. Despite the serious safety risk, GM and my local dealer have not offered a loaner vehicle while waiting for the repair, leaving me without a safe means of transportation. I am filing this complaint because I believe GM is not taking sufficient steps to protect customers from a known and documented safety hazard.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
Vehicle: 2021 GMC Yukon Denali Component: Fuel System, Gasoline – Fuel Pump Control Module Incident Date: 7-10-2025 Mileage 61,263 Location: SR 2006 Coats, NC Summary of Complaint: While my wife was pulling out of our neighborhood in our 2021 Yukon Denali, the vehicle suddenly shut off while navigating a slight curve. It came to a complete stop in the roadway and could not be restarted. The engine would not crank, and the vehicle could not be shifted into neutral, making it impossible to move out of traffic. The Yukon remained disabled in the roadway for over an hour and ultimately had to be towed. Upon inspection, the dealership mechanic immediately identified the issue without even running diagnostics. He confirmed it was a failed fuel pump control module, which he stated is a common issue with this model. This failure represents a serious safety risk, particularly had it occurred on a high-speed interstate or in dense traffic. A sudden loss of power and inability to move the vehicle can result in dangerous roadside situations or collisions. GMC needs to address this recurring defect before it leads to more severe incidents or injuries. No warning lights or indicators appeared prior to the failure.

ENGINE
Vehicle engine seized. Approx 80,000 miles. After discussion with mechanic and dealership, this problem is common with GM L87 6.2L gas engines. Engine seize likely caused from defective crank bearings. No warning light, oil was in engine, vehicle recently serviced. No oil warning light on dash or temperature sensor on dash, or check engine light. Drove car on road trip - when arrived at destination parked car - few hours later went to start vehicle and wouldn't start. My VIN is not subject to recall - currently; however, many 2021 GM engines are recalled. Why wouldn't my 2021 engine be included in this recall? Or all customers notified of potential dangers? I frequently drive carpools with many children in the car - and an engine seizure at any point while driving puts me as driver and any passengers at risk. Vehicle currently being towed to dealer for 2nd diagnosis. First autobody shop diagnosed with engine seizure.

ENGINE AND ENGINE COOLING
I am writing to formally express my concern and frustration regarding the prolonged delay in implementing a remedy for General Motors Safety Recall N252494000, which affects vehicles equipped with the L87 6.2-liter VB engine. This recall, issued in April 2025, was prompted by serious safety concerns involving sudden engine failure and loss of propulsion-conditions that significantly increase the risk of a crash. Despite the recall being acknowledged and a Special Coverage Bulletin (N252494003) issued in May 2025, there has been no clear timeline or actionable fix provided to affected vehicle owners like myself. The root causes, as identified by GM, include rod-bearing damage due to sediment and out-of-spec crankshaft dimensions-both stemming from supplier manufacturing defects. Given the severity of the issue and the number of vehicles involved (nearly 600,000), the lack of timely resolution is unacceptable. I urge the NHTSA to take further action to ensure that GM expedites the development and deployment of a permanent fix. Vehicle owners deserve transparency, accountability, and above all, safety.

I have again taken my vehicle in for about 8th time trying to get an understanding of why my vehicle vibrates. Again, I was told that the problem could not be duplicated. However, when picking up, I had a discussion with the service manager whom had driven the vehicle as well.. He stated that he felt and heard something from the rear end. I explained that I had the differential fluid change about 2 months ago due to a growling noise when making a left turn. He printed the service bulletin for the differential and put it with my paper. I was told I would receive a call from him the following Monday to bring my truck back in to further investigate because it sounded like the vehicle has a bad rear end. I have not received a call back and have attempted to make contact with service manager twice. My powertrain warranty is almost up and fear that after is when they will finally make a diagnosis of the issue. My engine and transmission vibrates and the whole vehicle shakes when cranking and turning off. This is in addition when driving at any speed. At idle it vibrates and can be felt throughout the entire vehicle. I am afraid that this vehicle is going to stall or fail why traveling with my family. The problem is only getting worst, transmission fluid temperature is starting to rise higher than normal. I am just afraid at this point that I have wasted thousands of dollars on a vehicle and GMC is not willing to fix the problem. I have the L87 and just not understanding with the problems I am having why my truck hasn't been recalled. It was built before 07/2021 when the Arlington plant had to stop make on rear axle drive shaft for propulsion. This truck is a safety hazard. 3rd notice to NHTSA

UNKNOWN OR OTHER, POWER TRAIN
I am filing a complaint regarding a potential safety defect in my 2024 GMC Yukon Denali (approx. 25,000 miles), which has been in the dealership’s service department for about 30 days due to a faulty valve body in the transmission system. There is currently no estimated date for repair completion due to a lack of available parts. This is the second time the vehicle has been in the shop for the same unresolved issue. Earlier in 2025, I brought the car in due to driveability concerns and error messages appearing on the dash, but the dealership dismissed it and claimed I had “turned the vehicle on wrong,” despite it having a push-button start. The problem persisted until June 2025, when they finally diagnosed the valve body failure. This issue directly affects drivability and vehicle safety, particularly during acceleration and gear shifting. I am concerned that General Motors is aware of widespread valve body and transmission failures in these vehicles, yet continues to produce and sell new units while failing to ensure parts are available to support timely repairs. It is unacceptable that a major safety-related transmission issue can sideline a relatively new vehicle for over a month with no resolution in sight. GM’s lack of urgency in addressing this defect suggests a disregard for consumer safety and reliability. I respectfully request that the NHTSA investigate this issue as a potential pattern of safety defects in GM’s full-size SUV transmission systems.

While driving to Lake Placid, NY, I experienced sudden loss of propulsion as I was driving approximately 60 mph. I was able to brake and pull over to the shoulder. I was not able to restart the vehicle - engine was dead. We were flat bed towed to a garage in Lake Placid where it was confirmed that the engine was inoperable. The vehicle is now at. GM dealer in Potsdam, NY. I believe this engine should be part of the recall!!

FUEL/PROPULSION SYSTEM
While driving the vehicle shut off, leaving my family stranded in the middle of traffic. It was a 90+ degree day and my family was stuck in a hot car unable to move off the roadway. This was very unsafe. No warning lights prior, the engine just stopped. After multiple times trying to restart the vehicle, the battery died. After waiting several hours, the vehicle was towed to the local dealership where it was determined that the driver fuel control module needed replaced and re programmed.
