| Sep 2024 | FORWARD COLLISION AVOIDANCE | The contact owns a 2024 GMC Sierra 1500. The contact stated that while operating the vehicle, the automatic emergency braking system had malfunctioned and the vehicle did not stop when needed. The contact stated that while driving at a low rate of speed the collision avoidance system had activated, but the automatic emergency braking system did not activate, causing the vehicle to crash into the rear of a second vehicle. During the crash, no injuries were reported and no police report was taken. The cause of the failure was not determined. The local dealer was notified of the failure. The manufacturer was not notified of the failure. The failure mileage was 500. | Crash: Yes Fire: No | 500 |
| Sep 2024 | ELECTRICAL SYSTEM | 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. | Crash: No Fire: No | Unknown |
| Aug 2024 | ELECTRICAL SYSTEM,SERVICE BRAKES | 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. | Crash: No Fire: No | Unknown |
| Aug 2024 | EXTERIOR LIGHTING | The backup camera is useless at night. When backing up at night the camera is so dark you cannot see more than a foot or two behind you. If someone or something is behind you you will never see them before it’s too late. The camera is supposed to be a safety feature! I talked to the dealer service department about this and they said it’s a design flaw with GMC and nothing they could do. I Also looked online and see several people complaining about the same thing. This truck has as of today 268 miles on it. I called GMC help center and just got the runaround telling me I would have to go back to the dealer for them to fix the problem even after telling them several times that the dealer said nothing they could do it’s a design flaw with GMC. I believe GMC should be made to do a recall and fix this safety problem. | Crash: No Fire: No | Unknown |
| Aug 2024 | ELECTRICAL SYSTEM,EXTERIOR LIGHTING | 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. | Crash: No Fire: No | Unknown |
| Aug 2024 | EXTERIOR LIGHTING | At night, when put into reverse, the exterior reverse lights do not illuminate enough to safely use the rear view mirror or backup cameras to safely navigate in reverse. I have owned a new vehicle every other year for many years and I have never experienced this any any other vehicle. I am going to look at aftermarket lighting options to be used when in reverse. This is a very big miss and safety concern on any new vehicle now days, let alone on a $80,000 pickup truck. | Crash: No Fire: No | Unknown |
| Jul 2024 | ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL,ENGINE | 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! Thank You, [XXX] Cell: [XXX] Email: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Jul 2024 | ENGINE | I was stopped at a light while I was in drive. While I was waiting for the light to change the truck shut off suddenly with no warning. The dash message said to restart truck. I had to put it back in park then hit the push button to restart truck. It started right away. The truck had enough fuel and no reason to shut off on its own. The truck has less than 1,200 miles when this occurred. The truck had a shudder when it downshifted prior to this happening and then shut off about a minute later. Some shuddering seems to be the way the truck downshifts. This is dangerous if you have to just slow down and takeoff again and then it shuts off on it’s own. This can cause a crash. | Crash: No Fire: No | Unknown |
| Jul 2024 | EXTERIOR LIGHTING,VISIBILITY/WIPER,BACK OVER PREVENTION | Extremely poor rear camera quality at night. Common complaint on GMC and Chevy 2023/2024 models. Unsafe to reverse at night due to poor camera image quality. Cadillac has already issued a recall on their units which are identical to the GMC and Chevy. Many posts on Facebook gmc at4 and Chevy zr2 owners groups about the safety issue | Crash: No Fire: No | Unknown |
| May 2024 | UNKNOWN OR OTHER | Multi-function tailgate lowers without warning. Issue has occurred four times over the past week. The first issue resulted in cosmetic damage to the upper part of the gate. | Crash: Yes Fire: No | Unknown |
| Apr 2024 | ELECTRICAL SYSTEM,SERVICE BRAKES,ENGINE | 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. | Crash: No Fire: No | Unknown |
| Apr 2024 | EQUIPMENT ADAPTIVE/MOBILITY | The amber light for being to close to another vehicle in front of you does not come on in the dash in my case less than half a truck length ahead. It does not have any sensors on front or rear because Dealer said it was because of lack of chips. There must be someway to adjust this for further notification then a half a truck length. | Crash: No Fire: No | Unknown |
| Apr 2024 | STRUCTURE | The tailgate unlatched while driving. This caused the paint on the tailgate to rub off on the jack of the trailer that I was hauling. This could have caused items in the back of the pickup to fall out onto the road. There is a current recall for 2021-2023 GMC Sierra's with the same issue, but my 2024 GMC Sierra is not included in the recall. The vehicle is going to be inspected tomorrow by the a body shop. There were no lights or messages prior to the failure. | Crash: No Fire: No | Unknown |
| Mar 2024 | ELECTRICAL SYSTEM,EXTERIOR LIGHTING | 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. | Crash: No Fire: No | Unknown |
| Mar 2024 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |
| Mar 2024 | SUSPENSION | Purchased 2024 GMC Sierra 1500 Pro 2/28/2024 with 6 miles on it. Drove vehicle home (20 miles). Picked up and dropped off Grand Daughter from school. Proceeded to my Mom's house and took her for a ride then came home. Next afternoon went to take out garbage and noticed puddle by passenger rear tire. Got under truck and found shock to be completely wet. Called Dealer and made appointment to bring truck in next morning. Brought truck in next day and Dealer confirmed that shock was blown. Shock is not in stock but was ordered. Currently waiting for delivery to set up appointment to replace shock (Only the one that is blown of course). Truck now has 108 miles. 60 of those miles are driving from, back to and back home from the dealer. Now it sits with cardboard under it and once repaired, I have the bonus of scrubbing multiple oil slicks off of my driveway. Glad I wasn't towing or carrying a payload... | Crash: No Fire: No | Unknown |
| Feb 2024 | STRUCTURE | UNKOWN. It came like that. I took the truck to the dealership to be inspected and I was told that it was a manufacturing problem. | Crash: No Fire: No | Unknown |
| Feb 2024 | BACK OVER PREVENTION | The contact owns a 2024 GMC Sierra 1500. The contact stated while reversing in a rural area, the back-over prevention camera failed to display an image. The vehicle was taken to the local dealer who stated the vehicle was operating as designed. The vehicle was not repaired. The contact independently added lights to the rear of the vehicle however, the failure persisted. The contact referenced NHTSA Campaign Number: 22V709000 (Back Over Prevention) as a possible solution however, the VIN was not included in the recall. The manufacturer was notified of the failure and explained that the supplier was changed in 2023 and the camera was operating as designed. The failure mileage was approximately 12,000. | Crash: No Fire: No | Unknown |
| Jan 2024 | UNKNOWN OR OTHER | The driver's side floor mat will not stay in place because the device that is supposed to hold it in place is broken. The floor mat is now able to move forward and interfere with the function of the brake and/or accelerator. Both the dealership (Castle Rock GMC, Colorado) and GMC Customer Care (Case #: 91-11325687695) have ignored all requests to address this and other issues. I have also written letters to GMC Corporate and the Castle Rock GMC General Manager, both of which were also ignored. | Crash: No Fire: No | Unknown |
