2024 Chevrolet Silverado problems

“While traveling down the road at approximately 65 mph, I lost all power to the truck while towing an empty 3500lb trailer. I was unable to restart vehicle and had to have it towed to a dealership at my expense.”

“Conditions: Night, Raining, apx 50*F. Traveling on the highway apx 70 MPH with a loaded 18ft enclosed trailer (within the advertised towing limits of the truck). I accelerated to pass a tractor trailer. the transmission attempted to downshift, resulting in a loud bang and shudder. I attempted to accelerate once more. This time the transmission tried to shift, the rear wheels stopped turning for a second or two, resulting in a slide and requiring steering input to maintain the vehicle traveling straight. The rear wheels unlocked and began turning again. I coasted down to apx 55mph and attempted to maintain a lower speed until the next exit. While trying to maintain a safe speed for surrounding traffic, the transmission attempted to downshift. This time resulting in apx 4-6 seconds of the rear wheels stopping and skidding, resulting in a slide situation requiring steering input to remain in control of the truck/ trailer while the rear tires slid. I stopped on the shoulder, locked the truck into gears no higher than 4th gear and drove to the nearest dealer without further issues.”

“Engine wiring harness. Apparently engineeed, designed or installed poorly. With normal use, multiple points are subject to wearing of insulation or wire fracture. While on cruise, transmission went into limp mode. Dealer verified exposed wire, replacing entire harness.Chevy has service bulletins out on the issue but nothing to the customer.”

“On October 9, 2026, I was driving my 2024 Chevrolet Silverado 1500 RST on a rural road at approximately 35–54 mph when the engine unexpectedly shut off without warning. There were no warning messages or indications of a problem before the engine stopped running. The instrument cluster remained illuminated, but the vehicle lost engine power and propulsion. I was able to bring the vehicle to a stop safely without an accident or injuries. However, the sudden loss of engine power while traveling at road speed created a serious safety concern. After the vehicle stopped, I attempted to restart the engine. The engine would crank normally but would not start. Diagnostic trouble code P129F was identified using a scan tool and was also displayed through the Chevrolet application. The vehicle is currently at an authorized Chevrolet dealership for diagnosis and repair. Based on the diagnostic code and reported symptoms, a failure of the fuel pump control module is suspected, although the dealership has not yet confirmed the cause. I am concerned that a sudden, unexpected engine shutdown could result in a collision, particularly if this failure occurs at highway speeds, in…”

“The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that the vehicle had been experiencing inaccurate DEF gauge readings since the purchase, and the failure mostly occurred while towing a camper or trailer. The contact stated that while driving 70 MPH on the highway and hauling a camper, the message that the DEF tank was empty and needed to be refilled was displayed, and the vehicle went into LIMP Mode and decelerated to 35 MPH. The driver continued driving and pulled over to a safe location. The vehicle was taken to a dealer, where it was determined that the DEF tank needed to be replaced; however, the manufacturer denied authorization because the required preliminary procedures had not been completed. The manufacturer General Motors LLC was notified of the failure by phone. The failure mileage was approximately 4.”

“I pulled off the interstate after traveling 70mph with cruise control on. I then pulled into the Walmart parking lot and started to enter a parking spot rolling at 5mph and accidentally brushed the resume cruise control and the truck shot me forward and I came within inches of the car ahead of me because the truck suddenly started accelerating.”
