GMC Complaints

Back up camera just started showing a blue screen with message that stated service back up camera. No accident, has not been to dealership. Just started 8/15/2025. No warning given.

I am the owner of a 2024 GMC Yukon Denali/AT4-T1, currently subject to GM Program #N252494000 for the L87 Engine Loss of Propulsion engine defect that can cause sudden engine failure, loss of power, and safety hazards. My vehicle has approximately 18,000 miles and is my primary mode of transportation. GM has informed me that I cannot request an immediate inspection and that they are randomly selecting affected vehicles for inspection without a clear timetable. This means I must continue driving a vehicle with a known safety defect that could fail at any moment — creating an unreasonable risk for myself, my passengers, and others on the road. My dealership has confirmed they cannot perform the inspection until GM activates my VIN in their system. No estimated timeframe has been provided. Given the severity of the defect and the potential for catastrophic failure without warning, I respectfully request that NHTSA investigate GM’s phased approach to inspections and determine whether this practice is consistent with the safety obligations under 49 U.S.C. Chapter 301 and related regulations. I also request guidance on how I can have my vehicle inspected immediately to mitigate risk. Thank you for your attention to this matter.

The onboard accident emergency notification system has failed after 2 years. The SOS and Onstar are not functional. Car has no data communication with the network. Was confirmed by Crenwelge Motors in Kerrville Texas. It is a GMC dealer. This is an ongoing problem with many Yukons made from 2022 to 2024. GM has not addressed the issue with a recall and does not have the parts to repair this safety system.

While driving the fuel pump failed and started spraying gas everywhere in the engine compartment.

Complete engine failure and lock up driving 70MPH. I was very lucky to not wreck the vehicle when this occurred with my family of 5 present. Had towed to the dealership and diagnostics performed. Diagnostics confirmed crankshaft issue and complete engine failure requiring engine replacement. I was informed that this was the same issue that is under current recall, but the 5.3L is not part of it. This is the same crankshaft issue that has been recalled in over 700K 6.2L GM motors. I am being told that the 5.3L engine is not covered under the recall and i am 100% responsible for all costs related. I want this 5.3L issue reported and documented to help extend the recall to the 5.3L engines in the future
