Rear right clunk in rear suspension. Dealer kept truck for 2 days and can't figure it out. Worried it could be a suspension nut or bolt and could cause a crash.
The contact owns a 2026 GMC Sierra EV. The contact received notification of NHTSA Campaign Number: 25V594000 (Electronic Stability Control (ESC); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that while driving over uneven pavement, there was an abnormal bumping sound coming from the front passenger's side suspension. Additionally, the contact stated while driving at various speeds, the contact noticed an abno…
Component/system malfunctioned: Adaptive Cruise Control integrated with Traffic Sign Recognition/Speed Limit Assist (camera-based speed sign detection and automatic speed adjustment). Vehicle available for inspection upon request. While driving ~35 mph in 35 mph zones with Adaptive Cruise Control engaged, the system repeatedly misread speed signs (or GPS data) as much higher (e.g., 75 mph). The vehicle then automatically accelerated aggressively toward the incorrect higher speed without driver accelerator input. Acceleration is sudden and stron…
Truck has airbag service issues since day 1. I’ve taken to the dealership and they can’t find any issues even though the service safety system continues to appear. Ac issues and charging issues as well. I’ve attached documentation.

Reported: 2025-09-11 (September 11, 2025)
General Motors, LLC (GM) is recalling certain 2026 Chevrolet Silverado EV and GMC Sierra EV electric vehicles. After experiencing an electronic stability control (ESC) system malfunction, the ESC malfunction warning light may not illuminate on the next key cycle. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 126, "Electronic Stability Control Systems."
Consequence: An indicator light that does not illuminate may fail to warn the driver of an ESC system issue, increasing the risk of a crash.
Remedy: The EBCM software will be updated by a dealer, or through an over-the-air (OTA) software update, free of charge. Owner notification letters were mailed October 15, 2025. Owners may contact Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is N252515340.

The truck bed cover is not secure, it fits in via a channel with no straps or other protections and so when driving on the highway, it flies off from the connection to the cab and you can’t see behind you. It then smacks into the car until you can pull over. There is no protection against this.
The passenger rear view mirror is completely flat, not concave like every other mirror we’re used to on a passenger vehicle. This mirror glass is only used on the passenger mirror of the EV trucks for some unknown reason. It is completely unsafe in such a large truck without huge blind spots. Because it appears to be zoomed you can completely miss cars otherwise viewable in blind spot. This also makes setting the passenger mirror up for towing very challenging and also dangerous. In addition the software for the backup titling mirrors works as …
I was driving and noticed a very strong smell of an electrical fire. The truck popped up a High Voltage Battery warning and several warning lights came on. We stopped, restarted the truck and the lights came on again, the smell returned as soon as we started driving. We drove the truck to Cable Dahmer GMC in Kansas City, MO. Service advisor Kracinda asked us to exit the vehicle as quickly as possible as it needed to be moved away from the building ASAP. It was parked several blocks from the building in a col de sac away from all vehicles. T…

Battery heating module failed. This resulted in small, hard to distinguish, "service vehicle" icon to appear on the dash with no further information. This warning icon first appeared during a long drive, then went away on its own and eventually came back. This failure would eventually make charging, particularly in cold weather, impossible and potentially stranding the occupants. The servicing dealership has confirmed this failure and is attempting to replace the module. However, parts for this replacement seem to be unavailable with no cu…
After the latest update from the Dealer, the integrated trailer brake module no longer shows an output of how much power it's applying to the trailer brake system. It just stays blank. I can tell that the brakes actually are being applied, however not having indication of them being applied and how much pressure is applied is concerning.
My 2025 GMC Denali EV has experienced repeated safety-critical issues, including severe torque pull under acceleration, making it difficult to maintain safe lane position and compromising steering control. This behavior persists even after inspection and is documented on video. The vehicle has also had repeated service brake assist faults, including one critical failure at under 6,000 miles and additional incidents that resulted in me being stranded out of state. Additionally, I have experienced ghost braking while reversing, where the vehicl…

The HVAC airflow-direction system failed and no longer correctly controls where the air is directed. Even when the windshield defrost setting is not selected, the system continuously sends airflow toward the windshield. This unwanted airflow causes condensation and fogging on the windshield that cannot be turned off or redirected, impairing the driver's visibility and creating a significant safety hazard. The airflow is also defective in the other ventilation zones. Air is not consistently directed to the selected dashboard, floor, or other ve…

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
No selected model years have a complete observation window. Choose an eligible year or a shorter window.
Incident date is preferred when valid and no later than filing; otherwise filing date is used. Model year approximates age. Equal observation time does not adjust for sales, distance driven or reporting delays. One complaint linked to multiple model years can appear in each cohort.
