This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Intermittent problems with various systems freezing up or not working: Windshield wipers freezing for several seconds mid-wipe. Nearly caused accident. Heads up display not retaining settings Seat controls (bladders that inflate deflate) intermittently working/infotainment screen freeze (where seat control is displayed). Lane departure warning inconsistently working (beeping) Radio quits playing for several seconds and screen goes dark Blinker stops blinking and then re-starts 6.2L engine slow/rough idle continuously hunting for stable speed (This is the only problem that is NOT intermittent). At times almost dies. A/C unit stuck on "hot" delivering 92 degree air when outside 72 degrees. Temp set at Low. (No A/C just trying to get fresh outside air in). Vehicle was under recall and control modules "reflashed" before purchased (new). Dealer reflashed which did not solve problems. Dealer cannot duplicate (but they only spend a little time looking at the issue). Has been in shop off/on for about 2 weeks attempting to resolve. Issues on occasion still occuring since Mid October 2024 purchase.
Truck thinks I-??m about to run into something and slams on its brakes. Last time it sent my sister to the hospital to get 6 staples in her head. Digital cluster goes on and off as well as the infotainment center. Transmission bangs and shifts horribly. 900 miles on the truck with a check engine light and transmission warning.
I bought this 2024 GMC Sierra new in February of 2024. I have been having several problems. Mainly the back up camera works intermittently. I have had my truck into the dealer 5 times for the same problem. I have contacted GMC to initiate a buy back. I have had the entire infotainment system replaced and am still having problems. My truck goes into the dealer, luther brookdale GMC, again 0ctober 17th, 2024 for the 6th time. I have been dealing with this problem for over eight months I have videos if it would do any good.
10/9/24: All interior vehicle sounds (turn signals, hazard lights, parking warnings, collision warnings, etc.) along with the audio sound system, are audible in my vehicle via the vehicles-??s audio system speakers. For reasons unknown and without warning, all interior vehicle sounds and the audio sound system cease to make audible sound; however, the infotainment display screen and the instrument cluster screen continue displaying normally and appear to function properly (system still accepts touch screen inputs and visibly displays volume knob input adjustments). So, in summary, a disconnect occurs between the infotainment system / vehicle audible warnings and the vehicle-??s speakers, through which the sounds emitted. We purchased our 2024 GMC Sierra 1500 AT4 as a brand-new purchase on 9/30/24 and it is completely stock, with no post-purchase or aftermarket alterations having been made to the vehicle. This issue has occurred on two separate occasions since the purchase date, with the occurrences happening on 10/8/24, and once on 10/9/24. When this sound-disconnect issue occurs, it will last indefinitely until we remedy the issue. The only remedy for this issue that has worked thus far requires that we completely shut the vehicle down, wait a few minutes, and then restart the vehicle. In researching this issue, I have found multiple comments over various forums by various users who have reported dealing with this same issue.

Stereo volume went to max, startled me while driving through residential neighborhood. Then muted itself and wouldn-??t work. Stereo reset itself and then played at normal volume but none of the controls worked until I restarted my truck. Bought it brand new last week
Backup camera fails to perform in poor lighting. Camera images are distorted appearing as a mix of colors The lack of clarity, renders the rear view camera as worthless.
The DIC randomly displays -??check trailer wiring-?? then says -??brakes connected-?? over and over. When this happens the brakes on the trailer quit working, all lights continue to work all the time. It hasn-??t been back to the dealer yet but I will take it when I can. Other vehicles have no issues with this trailers brakes when towing. I have replaced the trailer pig tail 7 pin plug, cleaned all connections etc. The only thing that works so far is to disconnect one of 4 electric brakes then the DIC is silent and 3 brakes function. I even replaced some magnets in the trailer brakes but they were working prior to the DIC message that began on my second towing trip. There is a technical bulletin for some GMC trucks but my model isn-??t listed as one. I believe it to be the controller or software since nothing seems to work as far as the trailer is concerned. It isn-??t my trailers issue-??I know they are going to say it is.
Backup lights are very dark making it very hard to see at night while reversing to the point where they are unsafe. Cannot see at all in rainy conditions.
To Whom It May Concern, This is a brand new 2024 GMC Sierra AT4 Diesel Truck with 4,000 miles. The first incident occurred when I was doing about 5 mph. The truck maintained its speed without my foot on the gas pedal and the cruise control was not on. Then when I tapped the gas pedal, everything return to normal. The second incident was about 2 weeks later in which the same thing happened. The third incident which was about one week later, I was doing about 5 mph and the truck accelerated on its own. I let the truck accelerate to approximately 28 mph. At that point I hit the brakes to stop the vechicle and pulled over. The truck was idling very high so I turned off the engine. All the ignition lighting remained on, but the truck would not restart. Even after removing the keys from the vehicle the ignition lighting remained on. At that point the truck had be towed back to the dealership which is Rainbow Buick, GMC in Covington, Louisiana. I've been told by the Rainbow Service Department that they do not know what's wrong with the truck. It's been sitting there for 10 days now was a dead battery. My salesman who I don't really believe, said he has the exact same truck and it happen to his tuck at 30,000 miles. I file a claim with GMC Customer Support but have yet to hear from them. I'm obviously very disappointed with my new truck, my salesperson, and service department. If there's anything you can do to help please let me know!

I was driving my vehicle, with my 9-year-old son in the back, when it seemed to completely lose power and shut down (while I was driving!). The power steering, brakes, and gas all gave out. I was able to steer myself toward the side of the road where I waited for a tow. The vehicle would not start, nor would it shift into neutral, which led to towing challenges. This is a 2024 vehicle that I've had for about eight months, and it completely gave out while I was driving with a child in the back, which is a significant safety concern. Nobody at the dealership or GMC is able to offer anything with respect to information on how or why this happened and what you are doing to resolve the issue. From what I see online, this is a known issue that GMC is likely to be sued for in the future.
Component or system failure: Complete failure of the headlights and interior lighting, including the dashboard after post remote start - ignition on. Safety risk: Headlights and other interior lighting would not activate leaving the vehicle completely dark. The only remedy was to completely restart the vehicle. Reproduced": No. The vehicle is brand new with less than 100 miles. Inspected": No warning messages: there were unpresented in the DIC. However, the vehicle also would not shift from drive.
The infotainment systems audio while driving decreases so much that you have to increase the volume to hear it and then will randomly increase to the correct volume level without warning and then decrease again.
