GMC Complaints

The entire instrument panel is blacked out. I can not see the speed, how much fuel and no waring lights etc. The screen flashes between black and dark blue and there is a repetative "ding" that I have no idea what is caused from since I can not see any warning lights, etc.This puts me and others at risk due to not being able to see any functions for operation of the vehicle, the speed or any indicator lights of vehicle issues. The dealer has seen the truck, and informed me that this is a known problem and they would have to order parts. According to the service department, parts for replacement will be covered under warranty/recall and they have been on order. It has been 3 weeks and they have no knowledge of when the parts will be in to make repair. There was no warning on this problem, the panel just went out.

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.

While driving on the highway at 70 MPH, the truck experienced a harsh transmission shift followed by a sudden loss of acceleration and entered shutdown mode to protect the engine. The steering became stiff, all dashboard warning lights illuminated, and a message appeared on the driver display indicating a transmission issue and advising to drive with caution. The RPMs surged and the truck struggled to maintain a speed of 45 MPH while the remaining at 4000 RPM. This created an extremely hazardous situation for both me and my passenger. I safely pulled into the breakdown lane, came to a complete stop, shifted into park, and turned off the engine. Upon restarting the vehicle, the Check Engine Light remained on, and the transmission continued to shift abnormally at low speeds, including noticeable shuddering.

Vehicle was in for routine service, oil change and tire rotation. Per the published engine recall bulletin [Manufacturer Recall Number N252494000] the recall directs the technicians to check for a DTC and if not present to drain and replace filter and oil using 0-40W oil, to replace the oil filler cap with new oil specification labeling, and provide a corrected page for the owners operating manual. All very simple steps. There is absolutely no reason for this check and service not to be performed during routine maintenance. GM is dragging their feet on performing a critical recall and should be held accountable for slow walking this recall. Servicing dealer claims they had ZERO 0-40W oil in the entire dealership. I can go to Walmart and get cases of this oil. Replacement Filler Caps, which must be replaced can be quickly produced by the tens of thousands if desired, which apparently is a very low priority for GM. Servicing dealer was Heritage GMC, Rockwall, TX. Desired outcome is to require completion of all outstanding recalls if the vehicle is presented for servicing regardless of reason. Further, to specify a definitive timeline to complete any outstanding recalls and have that information communicated to each owner. Manufacturer Recall Number N252494000 has not been completed at this time.

The contact stated while his mother was driving 75 MPH on the highway, there was a popping and ticking sound coming from the engine, and while depressing the accelerator pedal the vehicle failed to respond. The driver was able to pull over to the right side of the road and waited for tow truck assistance. A dealer was not contacted. The vehicle was towed the dealer and was diagnosed and determined that the engine needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure, and informed the contact engine would take a while to be ordered. The contact was referred to the NHTSA Hotline for assistance.

At low speeds when applying the brake, whether in a turn or traffic, the vehicle will shut off completely. This has happened multiple times and has almost caused accidents on a few occasions. It has also happened while just driving down the road, the entire truck lost power and then came back, the windshield wipers came on as well.

The contact owns a 2024 GMC Sierra 1500. The contact stated that after driving the vehicle for 20 minutes, the contact would feel significantly weaknand would faint. The contact later noticed that water was leaking from the windshield, which led to a mold infestation. The vehicle was taken to the dealer, and the contact provided a video of the leaking windshield to the dealer; however, the dealer informed the contact that the failure could be duplicated, and no issues were found. The vehicle was not diagnosed or repaired. The contact stated that the Aerotech company had confirmed the presence of mold in the air filter. The contact stated that she had a genetic predisposition to mold, and the mold infestation had caused the contact to sustain swollen sinuses, rashes, hives, to feel tired and to faint at times. The contact sought medical assistance, and the contact's Doctor provided a document that stated that it was unsafe for the contact to operate the vehicle due to the mold. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was approximately 10.

My son was making a left onto a freeway on ramp after traffic cleared and the steering wheel completely locked up resulting in him going over the curb and rolling completely over in a steep ditch. This occurred at a low speed (no more than 25mph), confirmed by the Life369 app. My son's description was that it felt like the wheels were against a wall and the wheel wouldn't turn even though he was using both hands in an attempt to turn. My son said there was no warning lights or any other indication that he noticed, other than the complete locking up of the steering. The resulting rollover into the ditch has totaled the vehicle so it was not inspected by any collision shop. I attempted to check the steering in the tow yard but the vehicle had no power.
