2024 Chevrolet Silverado 1500: fuel pump failure

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.

I have a 2024 Silverado 1500 Z71. I purchased new, within the first month I started experiencing issues related to the fuel. Stalling, dying, missing at idle and failing to start. I’ve reported it to the dealerships, with the same response unable to duplicate. Sept 22, 2025 I was driving alone rounding a curve in the road when my vehicle lost complete power causing me to loose control crashing into trees. I was unharmed physically, but mentally this hurt. To know this all could have been avoided had Chevy customer service or the dealerships listen and looked at the dtc that were clearly shown. P3187 fuel pump pressure performance low pressure. Stated failed since last cleared. Dealership did not acknowledge or discuss with me this dtc. Instead they gave me a multi point inspection stating unable to duplicate. There negligence caused me to wreck

I was taking a left from a stop sign onto a busy boulevard and as soon as I had passed the median I started losing acceleration and it felt like the transmission or engine was glitching or lugging. The engine began to try restarting itself possibly from the auto start-stop however I was now almost at a dead stop in the left hand lane in the dark. I promptly attempted to turn my hazards on, but they would not turn on while it was trying to start so I held the brake pedal down for light. I tried to turn the truck off and turn it back on however the hazards still did not work, none of the gauges went off when the truck was turned off, IE gas and voltage gauges were stuck. After attempting to put it into park and drive a few times I was finally able to turn the truck off, open the door and close it. At this point I was finally able to get the hazards turned on, however, it seemed like they would not stay on when the truck was trying to start so I could get out of the left hand lane. Fortunately someone stopped and we were able to push the truck off onto the median. After about a dozen attempts, the truck finally started, with the last attempt pumping the gas repeatedly for about twenty seconds. I drove hit for another twenty minutes and it drove okay with the engine light on. Onstar diagnostics mentioned possible fuel pump relay. I will note I did test drive a same year GMC equivalent model, and as the dealer went to gas it up, it would not start again. It ended up being the fuel pump relay.
