I am filing this complaint regarding severe, excessive oil consumption in my 2021 GMC Yukon equipped with the 6.2L V8 engine (VIN: [XXX]). The vehicle is consuming oil at an accelerated and hazardous rate. Specifically, the engine oil level drops completely below the viewable crosshatches on the oil dipstick well before the vehicle’s automated Oil Life Monitoring system reaches 50%. This level of rapid oil depletion creates a significant safety risk, as it puts the vehicle at risk of sudden engine stalling, severe mechanical failure, or total engine lockup while driving at highway speeds, potentially causing a crash. General Motors has issued Safety Recall N252494000 to address internal manufacturing defects within the 6.2L engine that lead to mechanical damage and heavy oil loss. Although my vehicle is a 2021 model with the exact 6.2L V8 engine experiencing the identical, severe oil loss symptoms detailed in the recall, my specific VIN is currently excluded from the recall list. I request that the federal safety agency investigate this issue and pressure General Motors to expand the parameters of Recall N252494000 to include all affected 6.2L engines exhibiting this dangerous defect.

My 2021 GMC Yukon has approximately 36,900 miles. On September 12, 2026, the vehicle was at an authorized GMC dealership and passed a state safety inspection. On September 19, 2026, the check-engine warning light illuminated and I returned to the dealership. The dealer performed diagnostic testing and told me the fuel pump pressure was approximately 400 PSI when it should be approximately 700 PSI. I was told the fuel pump needs to be replaced. The vehicle is currently at the dealership awaiting the replacement part: Fuel pump I was not aware of a fuel-pump failure before the warning light appeared. I am particularly concerned because this failure occurred at only approximately 36,900 miles. GM previously recalled 3,386 2021 GMC Yukons under the federal safety agency Campaign 21V‑739/GM Recall N212332040 for a fuel-pump power-control-module defect that can cause the fuel pump to fail or operate intermittently, interrupt fuel flow and potentially cause the engine to stall. My 2021 Yukon is not included in that recall and currently shows no unrepaired recalls associated with my VIN. I believe this represents a potential safety concern because inadequate fuel delivery or a fuel-system failure while driving could cause reduced engine power or an unexpected stall, increasing the risk of a crash. Given the low mileage, the dealer-confirmed fuel-pressure problem, and the existing fuel-pump-related safety recall affecting other 2021 Yukons, I am concerned that my vehicle may have the same or a related defect despite not being included in the recalled population. I believe the federal safety agency should evaluate whether additional 2021 Yukons should be included in a safety investigation or recall. I am paying out of pocket to have the fuel pump replaced and am filing this complaint to document the failure.A fuel-pump failure at only 36,900 miles is extremely concerning. I ask the federal safety agency to determine whether my vehicle has the same or a related defect and whether the existing recall population should be expanded.

1. What component or system failed or malfunctioned. The Fuel Pump Module failed unexpectedly while the vehicle was being driven. Failure caused the engine to stall, resulting in a complete loss of power and mobility. Unsure if part is available for inspection. 2021 GMC Yukon have a recall N252516900, but our VIN is not included in this. Can our VIN be added to this recall please? 2. How was your safety or the safety of others put at risk? The vehicle abruptly stalled while being driven through a parking lot, causing a complete loss of power and leaving the vehicle disabled in an active traffic area. Because the vehicle could not be shifted out of PARK, it became an obstruction, creating a hazard for other drivers navigating the parking lot and increasing the risk of a collision. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. After the vehicle was towed to a local mechanic on a flatbed truck, the dealer diagnosed and confirmed that the Fuel Pump Module had failed, which caused the vehicle to stall and lose power. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle was inspected by a local repair shot, which diagnosed the failed Fuel Pump Module. The vehicle was also evaluated during the towing process. To my knowledge, the manufacturer, police, or insurance representatives have not separately inspected the vehicle or component. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Prior to the failure, there were no significant symptoms indicating an imminent fuel system failure. When the incident occurred, the vehicle abruptly stalled, lost all power, and displayed a message indicating that the vehicle was "not in a condition to shift," preventing it from being shifted out of PARK. This message first appeared immediately following event.

As I was driving, the vehicle's air conditioning suddenly began blowing warm/hot air. Moments later, the check engine light and all electronic service stability lights illuminated on the dashboard. Simultaneously, the vehicle suffered a complete loss of electronic brake assist, resulting in an extremely hard brake pedal and a severe reduction in braking power. The vehicle also displayed a "No Drive Mode Available" message. Third-party diagnostic scanning revealed network power codes U3018, U3505, P00FF, and P0700, indicating a total loss of power to the Body Control Module (BCM). This is the second life-threatening incident with this vehicle I have experienced following a previous highway engine stall due to engine recall. The vehicle was towed to a GM dealership for diagnostic and emergency electrical repairs.

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 the federal safety agency
