"While reversing slowly toward a fuel pump at a gas station in a 2023 Chevrolet Silverado 1500 Trailboss LT, the vehicle's Reverse Automatic Reverse autonomous braking system erroneously engaged with maximum hydraulic force. The truck came to an instantaneous, violent stop without driver input or any physical obstacle present besides a gas pump off to my left and a car filling up way behind me. The deceleration forces slammed the occupants and caused a severe, immediate lower back and shoulder injury to the passenger/driver due to the extreme change in kinetic inertia. This appears to match GM TSB 24-NA-048 regarding faulty sensor calibration creating virtual bumper errors near reflective surfaces. I have not taken it to the dealer because of this since it just happened. I didn't report it to the police or insurance. The car just beeped at me while it slammed the brakes. I didn't see what it saw on the camera. It has not done this to me before.

As I was driving, the vehicle threw a CEL and I saw the RPM’s fall. This happened multiple times, twice at an all-way stop sign, and once at a major intersection resulting in me being stranded with my vehicle in the middle of an active roadway, unable to move my vehicle. I brought my vehicle into the Chevrolet Dealership and the service department is claiming that I need to pay $1500 for a fuel pump with a CEL code that is not able to be duplicated. There is a TSB 24-NA-139 regarding my issue saying that it is not the fuel pump, it is the fuel pump control module. My issue is that the dealership wants me to pay $1500 for a fuel pump solely off of their “guess” of what the issue is. The bulletin calls out the P102B as one possible code related to the issues. I refused this service since this is just the dealership’s guess of what the issue may be and I believe the fuel pump control module should be replaced for free under the 8yr/80k federal emissions warranty. I requested that the dealership check the module as a part of the $245 diagnosis I paid for and they are insisting that the issue is with the fuel pump.

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 received a notice via OnStar of a P129 code of a critical issue with engine or transmission system on my 2020 Silverado pickup after I pulled on to the highway. Vehicle reduced engine power warning and engine light came on. I was forced to put vehicle in neutral and restart vehicle several times. This code indicates fuel pump control module being defective. After researching, there seems to be issues with this on the the following; General Motors has issued voluntary emission recalls (such as bulletins N252516900 and N262558690) for the fuel pump power control module on select 2021–2023 Buick, Cadillac, Chevrolet, and GMC vehicles. The issue with my vehicle is the same.

I have received a voluntary recall notice on my 2023 Chevrolet Silverado. The recall states that the vehicle may have a condition which can cause the Fuel Pump power control module to fail. If this happens fuel flow to the engine could be interrupted causing the motor to shut off. Would this be considered a safety concern if the engine shuts down on th highway?

I was sent a notice of a recall regarding a fuel pump, power control module that needs to be taken care of, but it is not being accepted under my VIN number. I believe that there is this issue with my vehicle or something similar because every day I start the vehicle up for the first time and drive it. It is jerking me and does not have proper fuel or proper pressure to move the vehicle without jerking me. After 10 to 15 minutes it cleans up and drives better but then again we’ll redo it if I sit still for multiple hours and restart the vehicle again late in the afternoon it will do it all over.

While driving at Interstate speeds, the engine abruptly stalled, causing an immediate loss of motive power. I was able to coast off the Interstate to a surface street then into a gas station parking lot. Once stopped, the engine would not start again. It would crank repeatedly but never fire, like it was out of gas, but I had nearly 1/2 tank still. This is a safety concern having a 3yr old truck just die on you at highway speeds. This vehicle matches the exact year, make, and model of the expanded GM Emission Recall Campaign N262558690-01 (the federal safety agency ID 11037321) for Fuel Pump Power Control Module failures, but the VIN is currently excluded."

Was driving at highway speeds when truck shuttered and rattled and quickly slowing down. Warning errors on dash stated "Reduced Acceleration, Drive with Care", "Service Emissions System", "Service Traction Control", "Service ESC". Got vehicle to dealer and they confirmed the error code (P0202 - covered under powertrain warranty), but then also noted an error code for P129F where the truck would not start up. They are recommending a replacement of the Fuel Pump Power Control Module. GM had updated a the federal safety agency bulletin (original: N262558690 - Emissions Recall - Fuel Pump Power Control Module - July 15, 2026) on August 12, 2026 that expanded the population of qualified models to include the 2022 GMC Sierra 1500. However, on September 1 they issued an updated notice that said "GM has since identified certain 2022-2023 model year Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles that were erroneously included in this recall and are not affected by the condition." I believe my truck was originally included in the recall, was removed two weeks ago, and now my dealer has subsequently diagnosed a Fuel Pump Power Control Module failure with DTC P129F and recommended replacement This all follows a warranty repair I had to get two weeks ago on my Engine Coolant Control Valve (P1098), which was covered under powertrain warranty
