Following engine replacement per NHTSA for 6.2l GMC engine. I am submitting a safety complaint regarding my 2022 GMC Sierra 1500 Denali (refresh body style). The vehicle has experienced repeated failures of driver-assist features and safety system warnings, including: Dash messages: “Lane Keeping Assist System Unavailable” and “Service Safety Restraint System.” When the fault occurs, driver-assist features including Adaptive Cruise Control become inoperative. The issue has recurred multiple times, including after repairs. After one event, the truck sat parked approximately 10 days and the battery discharged to failure and required replacement. A dealership visit documented DTC U3000 (“Internal Electronic Failure”) in the front view camera module. The dealer replaced/programmed/calibrated the front camera on 02/09/2026 at approximately 58,405 miles (invoice/RO #285795). The symptoms have recurred despite prior resets and this repair. I am concerned about loss of driver-assist functions while driving and the presence of a safety restraint system warning. Please investigate whether there is a defect related to the front camera/driver-assist systems and/or electrical module behavior that can cause repeat faults and battery drain on this model.

The front forward-facing camera module has failed, causing cruise control and driver-assistance features to become inoperative. Dealer diagnosis indicates the front camera must be replaced and recalibrated in order to restore cruise control and safety systems. This failure disables cruise control and driver-assist features that were standard equipment on the vehicle at purchase, resulting in a sudden loss of functionality while driving. The dealer has provided a repair estimate of approximately $1,150, including parts, labor, and required calibration, at owner expense. Based on similar reports from other owners, this appears to be a recurring issue affecting this model year.

While driving on a two lane highway at approximately 60 MPH the powersteering on my truck failed with warning lights on the dash. I limped it to a town where I could get it scanned and they could not figure out the issue. The issue was intermittent for a few days until it was non-stop. It took over a month to get the reconfigured part from GM to complete the repair, GM had to reconfigure the part to fix the issue I was having. A faulty powersteering control module was the probelm and it required replacement of the entire steering rack and alignment. GM is aware of this issue clearly due to their choice to rework the affected part, but not issuing a recall in light of the issue to take full repsonsibility/reimburse customers that have suffered monetary damage due to their failure to propperly engeineer parts.

The vehicle is available for inspection upon request. While utilizing Super Cruise on the interstate in stop and go traffic conditions, the vehicle will come to a complete halt and jerk (as though you I slammed on the breaks). This has happened approximately 4 times and each time, driving conditions were good and during hours of daylight. The halt is very violent and causes the vehicle behind me to slam on their breaks. The latest instance occurred on Tuesday May 29, 2025 and forced the vehicle behind me to swerve off of the road. The emergency breaking warning does not sound nor is there a reason for it to do so as it has happened when the vehicle in front of me is moving with traffic and has not slowed down or applied breaks. The super cruise system also does not disengage or say that the road information is unavailable. The vehicle simply comes to an abrupt halt, to the point where if things are in the seats they will fly forward and then the system behaves as though nothing has happened. Traveling speeds vary between 10-20 mph when it malfunctions. The problem has not been reproduced and it shouldn't because it is a serious safety hazard for the driver and other commuters on the road. I was told a module software update would fix the issue however that did not. There were no warning lights that occurred prior to any of the instances.

repeated mechanical failures of my 2022 GMC Sierra AT4, which I purchased on October 26, 2024, with approximately 37,000 miles on the odometer. The adaptive cruse control is wonderful when it works but I have found even with the sensor clean the truck will slam on brakes on its own causing me to nearly be rear ended. It happens when driving into the sun and at night. I no longer trust adaptive cruse and use manual cruse. Within just 55 days of ownership, and after driving roughly 4,700 miles, the vehicle experienced a catastrophic engine failure without warning on December 20, 2024. This failure left the truck immobilized in a highly dangerous situation—stuck in the middle of a 65-mph highway at a red light, without the ability to shift into neutral and remove the vehicle from traffic. I was forced to activate the emergency flashers and exit the vehicle, standing helplessly on the side of the road while praying that oncoming drivers would see the truck in time to avoid a potentially deadly accident. The truck was towed to the dealership the following day, December 21, 2024, where it remained for an unacceptable 110 days awaiting a replacement engine. I finally took possession of the repaired vehicle on April 10, 2025. Shockingly, only two days later—after driving just 328 miles—the vehicle suffered a second catastrophic engine failure without warning. The truck is now inoperable once again, sitting in my driveway and in need of a third engine replacement. While the odometer currently reads 42,365 miles. This ongoing situation has been not only a major inconvenience, but also a significant safety concern and financial burden. I am extremely disappointed in the reliability and performance of this vehicle. This level of failure on a vehicle that is still under powertrain warranty is simply unacceptable.

There are many safety features that DO NOT work, like parking assit and basically all warnings like when backing up etc. They made me sign a form stating they are not responsible for safety issues stemming from this (our inability to sue) this should be illegal.

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE. NHTSA will continue to investigate complaints of engine failure outside the scope of recall 25V-274 as part ofEngineering Analysis (EA25007). To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
