2020 Chevrolet Silverado 1500: fuel pump failure

Filed Oct 7, 2026 · Acceleration, Fuel system · TX

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.

The component that failed was the wiring harness installed in the engine area. the harness was installed right next to a dip stick. The dip stick has a sharp metal piece welded to it and it punctured the harness cutting wires on the inside. This could have been a potential fire hazard. The problem was able to be reproduced, inspected and confirmed by a certified chevy mechanic at Philips Chevy in Frankfort, IL. The mechanic also showed me the failure point on the vehicle upon a visit. The dashboard lights were flashing randomly, headlights were very dim which it very difficult to see, android auto stopped working and not able to use hands free, so that became a safety issue, cruise control stopped working, and was receiving errors for a failed fuel pump.

Our truck would not start, we had to have it towed twice. We had a s Diagnostic run and the code was for the fuel pump. We had the truck towed to a local mechanic and they mentioned the open recall on fuel pumps for our make, model and year. We tried to schedule the appointment at the dealership for recalls, but our VIN was not on the list.

Engine misfiring multiple times over a period of 2 or 3 years. Took it to the dealership in Andrews Tx, could not duplicate misfire but saw over 600 misfires on a single cylinder, they said it was fuel pump failure. Replaced fuel pump. After a month misfiring started again. October of 2024 took it to dealership in San Angelo Tx, they were able to duplicate misfire, lifter failure. Replaced lifters and cam as it was beat up. One month after repair, vehicle started shuddering. Took it back to San Angelo service center, transmission issue, torque converter needs to be replaced. I refused the service as I would not spend $5,000 more after spending $10,000 to repair engine.

While driving home truck began to misfire and drop in RPM’s. Service ESC and Service Parking Brake popped up on my notification system. My Engine light was blinking and my Traction light was on. While i was turning into my street to get home, my engine shut off. The steering wheel and brakes became hard as the motor wasn't powering them. I was able to turn it on and get it into my drive way. Afterwards when trying to turn it on, it would turn on and shut off immediately. Chevy replaces a fuel pump module for a second time(recall), added a new starter and battery. After Three months they then told me I need a new engine because it has locked itself up. I purchased the vehicle with 32,000 miles and It currently has 49,000 miles. Chevrolet are not going to warranty me a new engine because i do my own oil changes (which were 2). Had this happened on the highway or in traffic, i would've been at a high risk of causing an accident considering power steering and brake system was not working properly.

Check engine light came on, I plugged my code reader in and was given P0498 ERROR CODE. Upon doing research and calling around to 3 different Chevrolet service centers I was told that it is a know issue with the fuel pump control module on all gm trucks. I am part of a truck group of over 150 and 85 of us has had this issue and all are currently waiting for the part to come in which is back ordered over months. Why has there been no recall and service bulletins yet if all 3 of the service managers agreed of the known issue.

while driving i smelled what i thought was strong exhaust from a vehicle in front of us. It was actually gasoline fumes entering the cab from my truck's engine compartment. I pulled over and investigated the smell, we had to let down ALL the windows and turn off the AC. There were no warning lamps. There was, however, gasoline dripping from around the transmission area of the underside. It was dripping on the exhaust which was causing most of the stench. It wasn't a heavy drip but enough for me to skip any other planned errands. When we got to the house gasoline was dropping from six or seven places under the car. The next day we set an appointment for the dealership to look at it. When I drove into the dealer the car was still gushing gasoline and I told them about the recall for the High Pressure Fuel Pump. It turns out that's exactly what it was. However, although my RPO (L82) matched the designated recall, I was told my VIN was not included and I would have to pay...bummer. I don't think the recall cast a big enough web to catch all affected vehicles. I have a video but no photos.

Vehicle didn't start; got stranded. Tried to jump start with another vehicle. It turned, but didn't turn on. Had it towed to mechanic (closed on Sunday). Was lucky to be in an area I was familiar with during the day and not traveling over 250 miles the following day with family at night. Mechanic called Monday and stated fuel pump has to be replaced after a diagnostic test. 2020 Chevrolet Silverado @ 50,000 miles
