    The vehicle experienced a loss of engine power accompanied by a check engine warning light and a “Reduced Acceleration”/reduced-power condition. The exact component causing the malfunction has not yet been determined. The vehicle and any affected components are available for inspection upon request. While driving the truck uphill toward our residence, the vehicle lost significant power and had difficulty maintaining acceleration. The truck stalled several times. The sudden loss of engine power while driving on an incline created a safety risk because the vehicle was unable to maintain normal acceleration and could potentially have stopped in traffic or created a hazard for other vehicles. The problem has not yet been confirmed or reproduced by a dealer or independent service center. The vehicle has experienced the problem while being driven, including the reduced-acceleration condition and multiple stalls. The vehicle will be inspected by a GMC dealer on Monday, September 28, 2026. The check-engine warning light illuminated, and the vehicle displayed a reduced-acceleration/reduced-power condition. The truck subsequently experienced significant loss of power while traveling uphill and stalled several times. These symptoms first appeared on September 14, 15, 22, and 23, 2026.

    Intermittent trailer disconnect and loss of electric trailer brake output while towing Airstream. The truck is connected to the trailer through the seven Way plug. There are no modifications to the truck. This is a safety hazard as I pull a 9000+ lb trailer. Trailer connection drops momentarily and integrated trailer brake controller loses communication with trailer brakes. I went on a 5000 mile trip and my trailer brakes were connecting in disconnecting consistently. Every time there was a disconnection or connection the vehicle would “ding ding. This virtually happened consistently while we were on this long trip. During the trip, we tried to wedge the plug tight and zip tie the door shut, attempting to keep the plug tight. My truck is at the dealership, waiting on a “tool“. This is the second time it has been in the shop for this issue. I supplied a picture of the dash message after it got tired of connecting and disconnecting. I feel this is a serious safety issue.

    While driving my truck on the highway at 65 mph the truck bucked hard and immediately downshifted into 2nd gear. This caused me to rapidly decelerate to approximately 40 mph, I am lucky there was not another vehicle behind me when this happened since rapid unexpected deceleration without brake lights is very dangerous. I had to drive the truck in limp mode at 45mph and approximately 4500 rpms to the nearest exit. This event illuminated the trucks check engine light and displayed a brief service 4WD message followed by a permanent reduced acceleration message on the dash.

    While towing my fifth-wheel trailer, I was descending a hill (I had my tow/haul switch engaged) when I noticed an issue with my vehicle. Upon reaching the bottom of the hill and beginning to decelerate, when applying gas to continue up the hill the vehicle shuddered noticeably. A warning light briefly illuminated on the dashboard and then turned off shortly afterward. Although the warning light went away, the vehicle continued to exhibit a slight vibration, particularly between approximately 25 and 50 mph. I was able to drive the vehicle home safely and subsequently brought it to the dealership for inspection. The dealership performed a diagnostic scan and retrieved fault codes. Based on their findings, they have determined that the transmission requires replacement and are proceeding with that repair. They also found a different fluid in the transmission fluid, they skipped the testing and got permission to change out the transmission

    I own a 2024 GMC Sierra Denali Ultimate 2500HD diesel that has been out of service for 52 days due to an oil cooler / service bulletin related failure. The vehicle is under warranty. The required replacement part is on national backorder and, as of today, has not shipped. The current estimated ship date is February 17. During this time, neither the dealership nor GMC has provided proactive communication. I have had to repeatedly contact them for updates. This extended inability to repair a critical component, combined with the lack of parts availability and communication, raises concerns about the reliability of this system and the manufacturer’s ability to support safe operation of the vehicle in a reasonable timeframe. The truck is my primary vehicle and is intended for towing and transportation. Being unable to repair it for nearly two months due to parts unavailability presents a significant safety and reliability concern.

    Loss of audio throughout an entire drive/ignition cycle. This includes the loss of the blinker click/clack audio when the blinker is on. When the loss of audio issue occurs, the driver has no audio input indicating a blinker is on even though the actual blinker is flashing to other drivers. Therefore, an unaware driver (due to no audio feedback) with a blinker left on could have another driver pull out in front of them thinking they intended to turn with the result being a collision.

    Safety Concern Report: 2024 GMC Sierra Gear Shifter Obstruction ⸻ Vehicle Information: 2024 GMC Sierra [Specify 1500/2500/3500] [Optional: VIN Number] ⸻ Description of the Problem: I am writing to report a design concern with my 2024 GMC Sierra. The location and height of the gear shifter on this vehicle significantly obstruct the driver’s view of the center infotainment screen and console, especially while seated in a normal, upright driving position. The gear shifter blocks important information such as navigation directions, ETA, media controls, and other on-screen notifications. This forces me to lean forward or reposition myself in an unnatural way while driving, which I believe creates an unnecessary distraction and increases the risk of driver error or loss of situational awareness. I have attempted to adjust my seating position, steering wheel angle, and seat height, but none of these adjustments fully resolve the obstruction. After discussing this issue with other owners online, I found that multiple GMC Sierra owners have experienced the same visibility problem. Some have even resorted to aftermarket modifications to address the design flaw. I believe this is a design oversight that affects safe vehicle operation. I respectfully request that GMC and the National Highway Traffic Safety Administration review this issue for potential corrective action. ⸻ Requested Action: Please investigate this safety concern and consider potential solutions, such as a recall, design revision, or retrofit option to improve screen visibility without forcing the driver into unsafe driving postures. Thank you for your attention to this matter.

    My truck is experiencing an issue that is already a recall for similar trucks, but my VIN is not included in the recall. My tailgate opens on its own. This sometimes happens when I am driving down the road. This is a safety risk because if I am hauling something in the back, and the tailgate drops down, there is a chance the load could fall out of the truck and harm another vehicle or person that is behind my truck. I brought the truck to the dealer and they said they could not find any evidence of this issue, even though they stated that it is a known issues with these trucks. There were no waring lamps or messages. The only symptoms are that the battery can die if the truck is not used for a day or more and that the tailgate opens on its own whether the truck is parked or driving.

Shortly after the alert warning goes off again and I turn the engine off and start it back up. It cleared the alert, I brought it back in on 06/15/2024. They reset sensor and fixed a recall on tailgate. I picked up truck, drove it for 2 months and TCM warning came up and threw truck into limp mode while pulling a 2 horse trailer. It turned a 3 hr drive into a 6 hr drive. I brought back to dealer on 8/19/2024 they had it for 4 days and they notified me that this is an on going problem. It is a transmission solenoid valve stuck open and they ordered the part and told me it could be months before the part gets here due to the ongoing backorder from all the other trucks that have the same problem. I use this truck for work and leisure to pull my boat and 2 horse trailer and now I have a vehicle payment to make and no vehicle to use. I cannot use it to work or anything else because it is at the dealer for an unspecified amount of time. I have read online that this is a major problem with this truck and GMC as well as the dealerships know about this problem and they still sold it to me.

    The Column Shifter that is installed on all 2024 GMC Sierra 2500HDs and 3500HDs poses a potential safety risk to its passengers and other drivers on the road. When the column shifter of the vehicle is in the standard drive position the shifter covers part of the screen and the direct path to the radio volume control dial and infotainment home button. It has been found and replicated that attempting to interact with the infotainment screen UI and the home button/volume control dial the driver may easily accidentally bump the shifter into the neutral position. Bumping this 8000lbs+ vehicle into neutral unintentionally can be extremely dangerous to its passengers and fellow motorists especially when hauling a heavy trailer or load like heavy-duty pickup trucks are designed to do. Bumping the truck into neutral can allow the truck to lose its acceleration capabilities and degrade braking capabilities as the engine would be disconnected from the drive wheels, limiting engine braking and exhaust braking. This kind of braking is commonly used to help stop the truck with heavy trailers and loads. This problem has been commonly referred to in multiple Facebook groups relating to the 2024 GMC Heavy Duty Truck. I personally have not had it inspected by any third party as there is not much they can do to remedy the issue. I personally recommend that General Motors redesign the column shifter in these trucks shortening it to come no further than the diameter of the steering wheel eliminating any interference with the infotainment system and the home button/volume dial. GM shall replace this updated shifter free of charge in all trucks just recently built. For GM's sake, it is important that this issue is remedied ASAP as the truck just began production and there is a limited amount on the road. This is available for inspection upon request.

    I leased this vehicle on May 17, 2024, expecting it to function as intended. Instead, within months, it suffered recurring and escalating failures that have rendered it unsafe and unusable. January 7, 2025, I brought the truck to Gates GMC for routine service and reported that it had lunged forward by approximately 2 to 2.5 feet while shifting into park. Additionally, it exhibited irregular acceleration and rough down shifting in lower gears. I also communicated the check engine light has come on and gone off on the dashboard over the past week a few times without receiving any information on the app. At this January 7th visit, GM performed Recall N242435631, supposedly addressing a known battery drain defect that caused total vehicle shutdowns. On January 24, 2025, I started the truck and was immediately overwhelmed by an intense chemical odor coming through the ventilation system. January 31 – February 1, 2025 – Erratic Engine Warning Lights & Diagnostic Failures On January 31, 2025, at 5:28 PM, on this key cycle the check engine light illuminated but failed to register in the GM app. On the next key cycle, the warning disappeared. The following morning, February 1, 2025, at 10:26 AM, the check engine light Appeared on the first key cycle before disappearing on the second key cycle. The onboard diagnostics system failed to log or retain these warnings. On February 7, 2025, the vehicle suffered a complete electrical failure. no electronic function whatsoever. Roadside Assistance attempted to jump-start the truck using a high-powered jump pack, but it remained inoperable. A ford super duty and jump pack were needed to force start the truck. February 10, 2025 the truck suffered another total electrical failure and required towing to Gates GMC. The app indicated the Brake System, Anti-Lock Braking System, Emissions System (Specifically the exhaust system), and Power Train requiring service.

• Tires4

  • Filed Aug 2026

    I bought this truck from a reputable GM dealership 2.5 weeks before this happening occurred. Tires only had 50k miles on them when they were rated for 80k miles: the front driver side Ttire ruptured while on major hwy in texas. No signs of air loss and the road was clear of any debris. Steering started to lightly shake and eventually came to a violent shake, then the front driver tire ruptured. Uncontrollable steering from the rupture caused the truck to slam and scrape into the concrete dividing barrier. If it were not for the other drivers around and being then cautioning their driving behaviors, this may have resulted fatally. Other drivers and my self may have easily collided with each other on a major traffic highway. I’m still extremely mindful of this happening again. This caused me as a customer, originally thinking this tire manufacturer is to be trusted, to not being a customer any longer as well as causing nearly $30,000 of needed repairs. From what I am reading from this site, plenty of other drivers have experienced the same, almost identical happenings. This is a safety issue that needs a recall on this line of tires and the manufacturer should be liable for all costs to the consumer witch includes vehicle rentals, hotel fees and insurance deductibles, s as well as the entire bill of repairs the insurance companies dish out. It appears from all of the complaints, Goodyear is producing unsafe products that is endangering consumers’ lives. Do the ethical thing Goodyear. Stand behind your product and protect, honor your customers. I have requested a subjugation claim with my insurance provider. The ruptured tire and related wheel are in my possession, available for inspection upon request. Police and GM roadside assistance were called as Onstar was prompted.

    Power steering randomly cuts out very random and intermittent. So far only done at low speeds but worried if turning in an intersection and i lose steering.

  • Filed Mar 2025

    My truck wonders down the highway. It has been to the dealership well over 4 times. They have aligned the truck multiple times, changed the steering gear box, changed the power steering pump, changed tires and nothing fixes it. It takes constant adjusting of the steering to stay in my lane on any road. Quite pitiful for a $90,000 truck. It is currently at the dealership for the THIRD time in the past 7 days because they can’t get the truck to stop leaking fluids since changing the power steering pump. Excessive play in the steering and has been like that since day one that I left the lot. My wife can’t even drive the truck because she feels unsafe with how much play is in the steering. The dealership won’t do anything about it and is offering $20,000 less than I gave for the truck now that I can’t tolerate it anymore. But I refuse to lose that much money with only 13,000 miles on it. I just want a safe and reliable truck for my business and my family. Unfortunately that is not what GM has provided me with.

• Forward Collision Avoidance3

    Unexpected braking at highway speeds. This has at least 50 times at highway speeds. The truck has experienced repeated false Forward Collision Alerts and un-commanded Automatic Emergency Braking events. Adaptive Cruise Control frequently detects roadside objects and vehicles in adjacent lanes, particularly on curves. The vehicle has never had windshield replacement, front-end damage, suspension modifications, or aftermarket accessories. This is creating a safety hazard because the truck brakes unexpectedly in traffic at any speed.

    The systems have become unavailable. Took to dealership and they were told it just needed a software update. Dealer performed update GM sent and did not work. Dealer was told GM engineers would need to find a fix. I complained to GM and asked that they replace the cameras, especially because the vehicle is under warranty, and I was told no because that won't fix the issue. They don't even know what needs to be done to fix the issue though, but won't try a camera swap. They told me I need to take it back to the dealer so they can run diagnostics on it when the issue happens. I don't know what is so hard to understand that the issue is always there; the systems don't work and my dash always has the light the forward collision system not on and given a message when I start the truck that it is not available. This began to be an issue around 9000 miles. It first started by saying window camera blocked due to frost, but when it was clear, and I cleaned every camera and sensor, it still would not come on. This was 1.5 months ago. I don't understand why they are not trying to expedite fixing this safety issue. The dealer can't do anything until GM tells them to change out camera or send another fix, but there is no software fix available. I can forward emails between myself and GM and you can clearly see they are not listening. If that would be helpful, please let me know how to forward them.

    Driving back to camper in the late evening and was listening to music and gps was on the screen when I was going approximately 32mph when headliner airbags on both sides went off causing me to hit my brakes and veer into the ditch. I was able to maintain pretty good control but did hit either a rock or stick or something that punctured my wheel sidewall. Unsure if a tree limb then got caught and tore off my bedcover that then left a small dent on the c column on the passenger side. I was able to put my truck in 4wd to get back fully into the roadway and walk about to see potential damage. At that time I only saw my tire was loosing air and bedcover was off aside from the airbag deployment. I slowly made my way home to assess further during complete daylight. I was not injured other than a cut on the hand due to the bedcover and a headache from the deployment. No hard hit or collision and truck did not make contact with tree trunk or any front end damage that would ordinarily come from someone going into the ditch.
