2024 GMC Sierra 2500 Owner Complaints

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.

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.

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.

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

The tailgate opens unexpectedly, it can be inspected but it is in for repairs on 6/15/26. There was luggage in the back and it could have fallen out on the freeway. The problem has not been repeated by the dealer, but it has occurred several times in the past. The vehicle had not been inspected by others. There was no warning that the tailgate opened. They start to occur randomly several months ago.

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.

I was merging onto the highway in my 2024 GMC Sierra 2500HD AT4X equipped with the 6.6L Duramax engine at about 50mph when the gauge cluster emitted a “Reduced Acceleration Drive With Care” message followed by a check engine light. The check engine light presented indicated a “P0747” and “P0700” code. The vehicle was then stuck in 5th gear at highway speeds. Luckily there was no traffic present during this event due to the reduced acceleration of the vehicle and confusion caused to the operator. This could have been a dangerous situation due to the sudden change in handling of the vehicle. I have since then had the vehicle towed to the dealership in which it was purchased from for them to do their investigation to see how to fix the issue. This is a very well known issue with these GM heavy duty pickups. There is currently a recall on these trucks for this exact issue but my truck at this point in time is not included in said recall. I believe the recall is for 2020-2022 vehicles. Mine happens to be a 2024 which uses the same transmission as the older model vehicles in the recall. There are many other owners of these trucks like myself who have experienced this exact same issue. I’m sure this isn’t the first time this issue has been reported either. Something must be done about this.

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.

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. Reached out to a shop to have them check it out and see if they can see any reason why those airbags would have deployed without force then causing an incident

The contact owns a 2022 Safe Haven 12-foot Flatbed Trailer. The contact stated that while driving approximately 10 MPH and towing the unloaded trailer with a 2024 GMC Sierra 2500, while slowing down to make a right turn, the trailer detached from the tow hitch ball. The contact stated that there were no warning lights illuminated. The contact stated that the aluminum arms on the hitch adjoined to the frame of the trailer was loose. The contact stated that because of the design of the hitch, the receiver that rests on the trailer hitch was not flush, and there was room for the trailer receiver to move up and down, causing the bolts to loosen. The contact called the manufacturer and was informed that it was the normal of the bolts. The trailer was taken to an authorized dealer, and the contact was informed that the trailer was attached incorrectly. The vehicle was not diagnosed or repaired. The failure mileage was approximately 1,200. The VIN was not available.

The vehicle went into low power mode and said to pull over. As soon as that message appeared the next warning appeared and said to shift to neutral and pull over immediately and attempt to restart. The vehicle immediately shut off after second warning before having time to pull over from first message. I was able to pull most of the way off the road as the vehicle had shut off there was no power steering and had limited ability to steer the vehicle. This all happened without advance warning or any other warning that there was an issue while traveling at over 75mph. Vehicle would not restart and needed to be towed. Dealer stated it was a fule control module that was hard to get due to a recall. But that my vehicle was not part of that recall.
