This Problem Across All Years
I purchased my 2024 GMC Sierra 1500 on July 4, 2024. Shortly after purchase, the vehicle began experiencing recurring electrical and electronic malfunctions affecting multiple safety and driver-assistance systems. These issues include power mirrors not consistently folding when the vehicle is locked, the digital speed (MPH) intermittently not displaying on the dashboard, driver seat memory not always setting upon entry, and blind spot warning indicators activating while driving when no vehicles or objects are present. More critically, the rear parking assist sensors do not function consistently and often fail to alert before contact with an object. I have backed into objects on multiple occasions before the sensors activated or without any warning, creating a safety risk while reversing. I first brought the vehicle to the dealership on January 13, 2025 for these issues, but they were not resolved. I purchased two GMC-branded trailer cameras in December 2024 that are advertised as compatible with this vehicle. On September 1, 2025, I returned to the dealership when the “invisible trailer” feature became inoperable. The trailer camera system frequently shows a black screen, cuts out intermittently, or fails to display an image. I returned again on September 11, 2025 due to continued failure of the invisible trailer feature and rear parking assist. The dealership kept my vehicle until December 2, 2025 (approximately one month), but the issues remain unresolved. I am scheduled to return again in January. These failures reduce rear visibility and compromise multiple safety systems. Despite repeated dealership repair attempts and extended service time, the problems persist, suggesting a defect involving the vehicle’s electrical system, sensors, software, or camera modules. I have photo and video documentation of these failures.

Every winter when the temps dip into single digits something on the truck freezes and causes a major malfunction. This winter (2025) is the second time I’ve had a problem with the truck freezing up and leaving me in “limp mode”. Last year the same thing happened. The def sensors freeze up and the heater shorts out leaving me stranded in my $70,000 truck. I now have 34miles remaining until my truck is limited to 55mph. This is a serious problem.

After pulling my 2024 GMC Sierra 1500 SLT into a parking space at a local store, I shut off the engine. I observed the lighted ignition switch and the dash icons were illuminated even though the engine was completely off. Having had my foot on the brake at the time I decided to test the ignition switch to determine why it was lit while the engine was off. When I pressed the start button there was a loud, whining starter like sound, grinding like metal on metal. The noise was so alarming that I immediately took my hand off the ignition. The engine was still off. After waiting a significant amount of time I tried to restart the engine. Exactly the same thing occurred. On the final attempt to start the engine, 15-20 minutes later, it started and ran quietly like nothing had ever happened. On returning to the vehicle my wife asked what all the loud grinding noise was about. She had heard it while she was inside the store. I advised her it was our truck! The incident was shocking to us both and because of its bizarre nature I was afraid to drive the vehicle back home. As I already had an appointment on November 6 at DeLuz Chevy for another incident, I called them on November 3 to add this incident to the existing appointment. This incident was added to the November 6 appointment. Unfortunately the service department did not assess the previous incident and only addressed this incident.

Radio cuts in and out. Screen goes black, or gets fuzzy looking. All radio control functions quit working. After I shut the truck off, the radio will stay on.

The contact owns a 2024 GMC Sierra 1500. The contact stated that while operating the vehicle, the windshield washer fluid activated unintendedly and sprayed over the front windshield, causing a visibility hazard for the driver. The vehicle was taken to the local dealer who repaired a loosened electrical wire, and the vehicle was repaired. Additionally, the radio cluster unintendedly deactivated, and the OnStar Service became unavailable. The vehicle was taken to the local dealer who replaced the radio cluster, but the failure persisted. The manufacturer was not yet contacted regarding the failure. The failure mileage was 3,000.

On [XXX] while traveling on a highway, the vehicle lost drive power—the gear selector would not remain in Drive and reverted to Neutral for approximately 10 minutes. This created a serious safety hazard due to sudden loss of propulsion in moving traffic. The event was captured by OnStar, which emailed an automated incident alert. I later received a GM safety recall notice concerning potential engine loss of propulsion for vehicles with the 6.2L L87 engine (NHTSA 25V-274 / GM N252494000/001/002). I presented the vehicle to Ewing Buick GMC (Plano, TX) on July 23, 2025 for recall service and retrieved it on July 28, 2025. Approximately one week later, during an interstate trip to Kansas City, the engine catastrophically failed about one hour from my destination, leaving the vehicle disabled on the roadway shoulder. Roadside assistance towed the truck to Briggs Auto (KS). Briggs Auto diagnosed engine failure and ordered a replacement engine. I was informed the engine is on back-order with no estimated arrival, and the shop is under-staffed, prolonging repairs. The vehicle remains out of service. The sequence—pre-recall loss of propulsion, post-recall service, and then engine failure within a week—shows a serious safety defect that can lead to sudden loss of power at highway speeds, risking a crash. Frequency: Loss of propulsion occurred at least twice (March highway incident; subsequent engine failure in early August). Warning Lights/Messages: [Gear refuse tom shift to Drive mode.] Injuries/Crashes: None, but risk was substantial due to sudden power loss. Dealer Involvement: Ewing Buick GMC (recall visit); Briggs Auto (diagnosis/engine order). Attachments/Supporting Docs: OnStar email, recall notice, repair orders, tow documentation, photos/video. Please investigate whether 2024 GMC Sierra trucks with the 6.2L L87 engine continue to pose a loss-of-propulsion risk after recall service and whether parts shortages/back-orders are delaying effective remedy INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

Intermittently there isn't any sound from informational center speakers, this includes not sound of the turn signal indicators working. No sound from any vehicle component, vehicle has the current software release from GM. the only way I've found to get sound again is to leave the vehicle set not running for some period of time, short off then back on doesn't seem to clear the issue. I've check with the dealer and from what I understand this is a known issue with 2024 & 2025 GM informational centers.

Subject: Urgent Safety Complaint Dear GMC Customer Service, I hope this message nds you well. I am formally reporting a serious safety issue with my GMC vehicle. The car has experienced multiple dangerous incidents due to likely electrical or software faults, losing power suddenly on two occasions while driving. This is especially concerning given the low mileage of 20,000 km and that the vehicle is still under warranty. Vehicle Information: • Model: GMC Sierra SLE, 2024 • VIN: [XXX] • Current Mileage: 20,000 km Description of the Problem & History: 1. First Incident (At 3,000 km): o The vehicle completely shut down due to an electrical or system software issue while driving. o The vehicle was towed to the dealer and held for over two weeks for repairs. 2. Second Incident (Recently): o The vehicle again lost functionality; the gear was stuck in 1st gear, and I was unable to manually shift. o This occurred while driving, creating another unsafe situation. o The vehicle was again taken to the dealer for repair, and to date, I have not been informed of the root cause. Actions Taken: The vehicle was brought to Sarhan, UAE (Sharjah), Al Ghandi Auto after the rst incident. Despite inspections and repair attempts, the issue has recurred, indicating it was not resolved. And I am prepared to provide photographic or video evidence if necessary. Additional Context: • The vehicle is less than one year old and has been regularly serviced on time at authorized centers. The recurring issues strongly indicate an underlying reliability or manufacturing defect. Due to the severity and recurrence of these failures, I refuse any further repair attempts. I formally request either a full refund or a replacement vehicle, as this is unacceptable for a new car. Please acknowledge receipt of this complaint promptly and advise on the next steps for a swift resolution.

Purchase the truck [XXX]. In January of 2025 it started to feel like the engine was slipping. Near the end of February, it was getting worse and the locks started locking/unlocking on their own. The vehicle stalled two separate times while driving on a main road. The first couple days of March, the car stalled, again on the road while the locks went crazy. Then, on [XXX], after I had pulled out of my driveway in my neighborhood, my car completely shut down. We had to have the truck towed to Coyle GMC, in Clarksville, Indiana. And, as of May 1st, it is still there. We have been told they need some cap for the transmission and they don't know when they will get it. They offered to give us a new transmission, but they don't know when they'll get it. I am making car payments on a car that I have not had since May 7th. Unfortunately, because I drive my car for work, it had it's 32000 miles on it, so I can't turn it in for the lemon law. I'm very lucky that my son and I were not injured when the car stalled in the middle of the road. This is an ongoing issue with GMC, and I think it should be illegal that they were selling these trucks. I have a brand new truck that I haven't driven in 2 months.

While exiting the highway and transitioning into a turn lane, my 2024 GMC Sierra AT4 (with 12,887 miles) suddenly and completely shut down without any prior warning. All vehicle systems—including electrical—failed simultaneously. This included the dashboard, steering assistance, and emergency lights, which significantly compromised my safety. I was unable to alert surrounding drivers or move the vehicle out of the traffic lane. There were multiple cars behind me, and I was placed in an extremely unsafe situation due to the sudden loss of control and inability to signal or restart the vehicle. I immediately contacted emergency services, and a police officer arrived approximately 10 minutes later to assist. Roadside assistance later pulled diagnostic code P0016 from the truck’s computer. I have since learned that this code corresponds to a known engine timing defect and is the subject of a recent GMC recall issued just days prior to the incident. The failure occurred without any warning lights, messages, or symptoms beforehand. The vehicle is now with a GMC dealer and is available for inspection upon request. To my knowledge, the issue has not yet been independently confirmed, but I believe it is directly connected to the recalled component.

Driving on the highway, moving to pass another vehicle, engine shut off forcing me to coast to the shoulder. No warnings and didn't notice loss of power until I saw that the vehicle had been shifted into neutral. Had 2 kids in the truck and could not get GMC service department on the phone, had to walk up an onramp in order to get my kids home with me in an Uber. This is a 2024 6.2L GMC with only 13,000 miles. Service department took over a week to check initial issues, said it was a fuse block which they replaced. Did not resolve the issue, then it was the starter, which did not resolve the issue, after 2 weeks they told me the engine was locked up due to internal failure and it will be several months before the truck is operable. GM has stated they the issue needs to occur 4 times before a buyback would be considered.

Truck just made a year old and killed on me in the middle of road. They are saying I need a new engine and maybe transmission. Could not shift truck into neutral, which left me stranded on busy road. For unsafe and had me nervous. Trying to get GMC to buy me out of this vehicle. Had same problem with 6.2 liter prior to this truck. Engine and transmission was replaced. They promised if I bought new truck, I wouldn’t have the issues and here I am again. This is terrible.

The contact’s son owns a 2024 GMC Sierra 1500. The contact stated that after coming to a complete stop, the “Service Traction Control” message was displayed on the instrument panel. The contact turned off the vehicle and waited for a while before attempting to restart the vehicle; however, the vehicle failed to restart. The contact stated that the “Service Steering Column” message was then displayed on the instrument panel. A dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 28,140.

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.

On 2 occasions now my tailgate has opened on its own. The first incident happened sometime after I got home from work for the night, when I went to leave in the AM my tailgate was resting on the garage door and had been scratched. The second time it happened I didn’t notice it while driving but when I went to close the garage door I looked back and saw the gate was open and partially sticking out of the garage. Nothing happened this time to put anyone at risk however there is damage to the truck and if it happened while hauling something could have come out and hurt someone or damage property. I have not brought it to a service center yet. No warning

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.

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.
