2024 Chevrolet Silverado 1500 fuel system problems

Filed Oct 10, 2026 · Fuel system · GA

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 heavy traffic, or in a situation where a driver cannot safely move the vehicle off the roadway. I am requesting that the federal safety agency document this incident and evaluate whether a potential fuel pump control module defect presents a safety risk to owners of 2024 Chevrolet Silverado 1500 vehicles.

Check engine light repeatedly comes on. Take it in, multiple Chevy dealerships “fix” the errors such as fuel line pump 5x, gear shift issues, modules that went bad and various other issues. I Routinely take care of vehicle (oil changes, tire rotations and service when needed) This truck will randomly shut off while driving (stop and go traffic ) I was told to turn off the start/stop which I do every time I get in the truck. However it recently wouldn’t turn over after going through a car wash, it would try and try till I manually stopped it. It’s running rough now and I pray everyday the check engine light doesn’t come on or that it doesn't just shut off mid drive. This truck has been hell on wheels and I bought it with 10 miles on it. Bought it from AutoNation in 12/2023.

Summary of Incident: On March 28, 2026, while traveling at 70 MPH on the Florida Turnpike, the vehicle suffered an instantaneous loss of motive power. The engine died abruptly with no warning. Upon reaching the shoulder, the electronic transmission locked, refusing to shift into Neutral or Park. The engine cranks but will not start. 1. Component Failure & Availability: The exact component is currently unknown, but the failure involves the Powertrain, Fuel System, and Electronic Transmission Control. The vehicle is currently at an authorized dealership and is available for inspection by the manufacturer or the federal safety agency upon request. 2. Safety Risk: The sudden loss of power at highway speeds created an immediate risk of a rear-end collision. Because the electronic transmission locked and would not allow the vehicle to be shifted into Neutral, it became a fixed object on a high-speed shoulder. It could not be pushed to a safer location, increasing the risk of a secondary accident. 3. Problem Reproduction: The vehicle was towed directly to an authorized Chevrolet dealership. As of this filing, the dealership is in possession of the vehicle, but the failure has not yet been reproduced or confirmed by a technician as they are awaiting formal diagnostic commencement. 4. Inspections: The vehicle was inspected by a roadside towing professional for transport. It is currently at the manufacturer’s authorized service center awaiting a formal diagnostic inspection. No police or insurance inspections have occurred. 5. Warning Symptoms: There were no warning lamps, "Check Engine" lights, or messages prior to the failure. No symptoms like rough idling or unusual noises occurred. The vehicle performed normally until the moment of total power loss.

The cam crankshaft failed. I was driving on the highway at a speed between 65-75 and my truck just cut off without any warning. Luckily, I was in far right lane and coasted over to the side of the road but it was very scary because I didn't control my truck at all. I called the nearest Chevrolet Dealership that was Kevin Whitaker and they give me the Chevrolet help contact phone and they sent a tow truck to pickup my truck about 1 hr later and I was stuck in my truck on the side of the road and I couldn't get out on the drive side because how close it was to oncoming traffic. Once I arrived at the dealership with my truck after asking the tow driver could I ride with him to the dealership. At the dealership they checked the truck with computerized device and the service advisor told me the truck code revealed cam shaft problems. I told him that I did see and warning sign saying low oil pressure once I tired to start up the truck again on the side of the road.

Vehicle does not indicate proper DEF level. Vehicle has stated several times that it is out of DEF but is not. The most recent time the vehicle was at a dealer and was noted as normal operation. Driving up to going the dealer: vehicle displayed message “DEF empty refill now vehicle speed restricted to 65mph”with a 500 mile count down. Vehicle was driven 489 miles of the 500 miles. Vehicle was taken to a dealer. Dealer confirmed that vehicle was not out of DEF, vehicle was at 40% DEF capacity (~2 gallons of fluid in a 5 gallon tank). Dealer noted that this was normal operation. This is not safe, the DEF system isn’t accurately reporting level. In other situations it hasn’t recognize DEF fills. This can potentially lead to the vehicle severely restricting speed or not allowing the motor to restart creating unsafe conditions for the passengers and other vehicles on the road way. Vehicle was under warranty at the time of the issues. Vehicle is currently just under 37,000 miles.
