2024 GMC Sierra 2500 Problems

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.

The contact owns a 2024 GMC Sierra 2500. The contact stated that while driving 5 MPH, the vehicle lost brake and power steering functionality, and there was smoke coming from underneath the hood. The contact stated that power steering fluid was leaking onto the engine. No warning lights were illuminated. The vehicle was towed to a local dealer, where it was diagnosed, and the contact was informed that the power steering pump had seized, the belt and hoses had failed, and the parts needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 40,832.

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.

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 contact owns 2024 GMC Sierra 2500. The contact stated that while driving 25 MPH and depressing the accelerator pedal, the vehicle decelerated and stopped independently. A dealer was contacted. The vehicle was taken to the dealer and was diagnosed with fuel pump driver control module failure. The contact was informed that the fuel pump driver control module needed to be replaced. The contact associated the failure with Technical Service Bulletin: 24-NA-139 (Fuel Pump Driver Control Module stalling or no-start conditions); however, the VIN was not included in the TSB. The manufacturer was notified of the failure, and informed the contact that the vehicle was under warranty. The failure mileage was 54,238.

During a drive home, while in motion, the tailgate of the vehicle opened on its own. This has occurred after the recall to repair this issue was already performed. I know the tailgate was shut prior to the drive because I back into my parking spot and walk the sidewalk behind my truck prior to starting the vehicle.

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.

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.

Traveling on I-10 doing approx 75 mph head a loud boom and saw sparks coming from the read drivers side of the truck. Truck was riding a bit low on that side. Pulled over and determined the tire had blown up. Currently doing the insurance claim and repair as there was substantial damage to the truck. No crash or involvement by other motorists. Did not hit anything.

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
