• 12/24/2025· ELECTRICAL SYSTEM,LANE DEPARTURE,BACK OVER PREVENTION

  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.

  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

  I am writing to express my significant concerns regarding the recurring issues with my 2024 Denali 6.2, which has been subject to multiple service visits since reaching 7,000 miles. Despite these visits, the underlying problem remains undiagnosed and reoccurs shortly after I retrieve the vehicle. Following the second oil change, the engine developed a persistent ticking noise. Over the past 13 month, I have invested over $200,000 with your dealership in the past 5 years!. My truck was recently held for two weeks for service. After I lodged a complaint, the General Manager suggested I seek service elsewhere. This recommendation was made after I responded to an email stating that, following the completion of repairs to the headliner, third brake light, and brakes/rotors, I would no longer be utilizing Crain's services. The headliner sustained water damage due to improper installation by your technician, and fingerprints were also evident. I firmly believe in transparent communication regarding service progress, which was notably absent in this instance. Both the General Manager and Service Manager deferred responsibility, instructing me to contact GM directly, only for GM to inform me that direct contact was inappropriate. This resulted in a continuous cycle of unaddressed concerns with the service manager. Currently, I am operating an $80,000 vehicle that has incurred damage from a technician and exhibits a ticking engine. Furthermore, the driver's side mirror, which was previously replaced due to shaking at highway speeds, is now exhibiting the same issue, despite a technician's assertion that this is normal. I also note that my brakes, with over 89% remaining, are beginning to squeak, which your team claims is normal. This assessment is difficult to accept.

• 12/18/2025· ENGINE AND ENGINE COOLING

  The contact owns a 2024 GMC Sierra 1500. The contact stated that while driving approximately 70 MPH, the vehicle started losing automotive power and stalled. The contact frantically maneuvered the vehicle across three lanes of highway traffic to get to the right shoulder and park the vehicle. During the failure, the check engine warning light and several other unknown warning lights illuminated. The vehicle was later towed to the local dealer. The cause of the failure was not yet determined. The manufacturer was also notified of the failure. The contact had previously received a letter regarding NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 48,301.

  I brought my 2024 Sierra in for its L87 recall. It passed. Two weeks later I had to bring it in for check engine light. They reset the system under a TSB that is known to occur with the l87 recall. Not a total of 300 miles of passing the recall I was driving and the engine started making a horrible noise and I started experiencing loss of power. I managed to get the vehicle safely parked. The dealer pulled the oil filter and said it had 100% metal contamination in the oil. The filter looked like a glitter bomb went off. It took 3 weeks, they replaced the engine with a remanufactured engine even though I told them new only. They also had to replace the radiator as it was polluted with metal.

  12/7/2025 8:48 AM Engine lost propulsion while driving 35mph enroute to residence. The engine cut off and at the same time we saw a cloud of blue smoke trailing the vehicle. The engine refired and propulsion resumed. I immediately looked at the dash display for an indicator light resulting from the lack of propulsion. There were no unusual indicator lights or messages but the tachometer needle dropped about an inch and went back up again rapidly. The engine had resumed running. This loss of propulsion and resumption occurred two more times while my foot was off the accelerator. After the third incident the vehicle seemed to be running normally. I stated we had only about two miles to get home and I hope we make it. The next day I called DeLuz service department to notify them of the incident. I left a message but my call was not returned. I updated service staff of the new incident when I dropped the vehicle off for a previously scheduled appointment on 12/11/25.

  My truck completely stalled and had to be restarted. I took it to the dealership to have it resolved. They wouldn’t look at the truck without a recall notice. Now there is a recall notice for my exact issue. I took it to be repaired by them but now they are saying that there is nothing wrong with the vehicle and are refusing to do anything about it stalling. They specifically said that I will have to stall and potentially get in a car wreck before they will repair the damaged engine. I have been very disappointed in this entire situation and would like to avoid driving a car that may end up crashing due to a preventable problem.

  While driving my 2024 GMC Sierra Denali Ultimate on the highway, the engine suddenly failed without warning. The truck shut off completely while I was traveling at highway speed. I was fortunate to be able to safely maneuver to the shoulder, but the sudden loss of power created a serious risk of a collision with surrounding traffic. The failure appears to involve the engine or engine control system. The vehicle engine is currently available for inspection upon request. Prior to the incident, there were no warning lights, messages, or unusual symptoms. The shutdown occurred abruptly with no prior indication of a problem. This vehicle previously received the NS25249400 safety recall repair on August 12, 2025, and it reportedly passed all required checks at that time.

  On Dec 4, 2025, my wife was driving at night on a Texas road going 75mph. Her truck died while driving and the truck shifted into neutral and computer said to restart. When she did, all electrical power was lost including headlights while traveling at 75mph at night. Vehicle eventually was started after she got to the side of the road. A check engine light was present. She made it to her destination with no further problems. Vehicle was taken to the dealership the next day. They said that she may have catastrophic engine failure that is common on the 6.2 liter GM motors.

  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.

• 12/08/2024· EXTERIOR LIGHTING

  The reverse or backup lights do not properly illuminate, as the angle does not allow for viewing dangers behind at night. The lights are angled to aim way too high, and the lights are aealed. No way to adjuat. An adult standing just three to five feet behind truck, the lights illuminate at chest level, meaning a small child could not be seen at all, even with the rear view camera. Speaking of the camera, it not longer displays low light situations. People are going to be injured or killed because of these lights, or lack thereof of. On researching, this is a known defect since GMC went to LED tailings in the 2024 1500. This problem was not in my 2024 3500 as they use different lights. This is a dangerous situation.

  On 29 November 2025 at approximately 1700hrs, I was driving my Blue 2024 GMC Sierra 1500 AT4X outside of Pampa, TX. As I was driving to my hunting location, my truck turned itself off and placed itself in neutral. I was driving about 30 mph down a single farm road with another vehicle approaching me from the front. I was unable to pull to the side due to farmland. I was able to flash my lights to get the other vehicle to slow down before having an incident. During this time, I had to let the truck slow down to a stop. My vehicle was already inspected for the engine recall and I was informed I had nothing to worry about. That everything was good. The truck is at Greg Lair in Canyon, TX. It did put me and my passenger as risk. I did not receive any warning before my truck turned off. The dealer confirmed today that the engine had seized. The engine was inspected during the summer before this issue. I had not warning when this happened. Was just driving and lost power. Looked down at the display and it stated to restart engine. I noticed my truck was in neutral when it came to a stop.

  The recall you are showing was completed 300 miles ago. There were no outstanding recalls on my vehicle on November 23, 2025. On this day I was driving home, at night and I heard a loud flapping sound coming from the front of my vehicle. I pulled over and checked the front and wheel wells, nothing was stuck. I got back in and started driving the flapping sound was coming as I pressed the gas, when coasting with no gas, there was no flapping sound. I managed to make it home and GM towed my truck the next day. The shop has informed me that the engine is gone. Even though I did the recall 300 miles ago, it was directly what they were looking for in the recall and did not find it. This clearly put me in danger.

  I was operating my GMC Sierra 1500 SLT in Hilo HI. As I was slowly turning left from [XXX] onto [XXX] my vision was drawn to the rear view mirror. My wife and I observed a huge smoke like cloud above the tailgate of my truck and beyond. I immediately reduced my already slow speed. Traffic was heavy and I was unable to safely assess the problem on the spot. When I arrived at my destination a few blocks away I found no physical evidence that it had occurred. It has not happened since. Even so, we were concerned enough to make an appointment with DeLuz Chevy in Hilo for assessment. Unfortunately in the interim I experienced another problem with the truck and asked that it also be addressed during the smoke related appointment. Again unfortunately the DeLuz service department did not assess the smoke incident during the service visit.

  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.

  Called multiple dealerships and found out there is a known problem with the valve body for the transmission in these vehicles, which mine is currently being towed today to the dealer. This is what happened to me today, I was driving with my two children on the interstate and all of a sudden I had no drive nothing so the speed reduced quickly. Well behind me there was a 18 wheeler on my back and almost ran into me because I had no more drive on my pickup. Then when it was safe to pull to the side of the road found out there is no reverse either. Making it even more unsafe to drive these vehicles. If I need my reverse to back my vehicle out of on coming traffic’s I would not be able to do so. But this is the big kicker, this valve body for these vehicles are not being produced by gm. The multiple dealer ships that I called have said all the same thing, this is an extreme safety issue that should be recalled.

  Exactly what was described in the N192220080 Recall on New Model 2019 Chevy Silverados in cold climates (Like Utah winters) so at 45,280 miles the oil line popped out just like the recall described There were no oil leaks or signs of oil loss in the driveway where the truck is parked. My [XXX] wife (The owner of this vehicle) was only 6 miles from our house on the way to a doctors appt when the “Oil Pressure Low Turn Vehicle Off” light came on. Luckily she wasn't on the freeway so was able to pull into a neighborhood where all of the oil shot out of the engine due to the oil cooler line detaching. Since the N192220080 excluded other trucks made in the same factory as the once recalled in Alaska & Canada, we received no warning of a potential issue like this existing for this model of Silverado. It is also concerning that a known faulty part in all New Model 2019 Silverado 1500s was only recalled in Alaska & Canada. But if we had purchased this truck and registered the vehicle in Alaska, it would have at that point qualified for the free recall replacement instead of the $1,600 bill we were blindsided with (Plus, if she was on the freeway and couldn't immediately pull over, we would have had a seized engine so the truck would have been nearly totaled) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

  On October 23rd at approximately 0900-0915 hours I arrived at a friends house located at [XXX] . As I normally do, I pulled up into the driveway which has a pretty significant incline. I shifted the column shifter into park, and turned off the vehicle via the push button ignition switch. The parking brake/hill brake system automatically engaged as per normal operation. I exited the vehicle and before I could shut the door, the vehicle began to roll backwards. The driver's side door hit me in the right shoulder which pushed me to my left and caused me to roll my left ankle due to the down slope of the driver way. While I felt immense pain in my right ankle, I was able to jump back into the truck and slam on the brakes, causing both rear wheels to lock up and skid in the driveway. I then turned back on the vehicle, noting that the transmission position was still in park, and the parking brake/hill brake was still engaged. I had to disengage the push button parking brake/hill-brake, shift the vehicle from park into drive to move back up the driveway. This time I ensured that the vehicle did not move after following the exact same steps. My truck under went an approximately 30 minute software "upgrade" approximately 2.5 weeks ago. I believe there was an issue where the park sensor did not fully engage, leading the vehicle to believe it was still in an operational gear, however it does not explain how it was able to not only over-ride the parking/hill-brake itself, as well as allow me to shut the vehicle off and exit the vehicle. This safety hazard has caused me an injury that has already caused me to miss 48 hours of work (I am a federal firefighter) and will require more missed time should surgery be required. There were no warning lamps, the backup camera was not engaged, the only audible sound was the beep that the vehicle makes when engaging the parking brake automatically.

  Gridlines on the backup camera work intermittently when backing. The issue has been occurring since taking delivery. 20 June 2024. The dealer has made (3) attempts at repairing and has not resolved the issue. A Buy Back request was submitted 9/2025 and denied. GM advised it is a known problem they are working on. Back up cameras with gridlines became a mandatory safety feature in 2018.

  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.

  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.
