2023 Chevrolet Silverado 1500 fuel system problems

Filed Nov 5, 2026 · Engine, Fuel system · NM

My 2023 Chevrolet Silverado 1500 equipped with the 6.2L V8 engine experienced a sudden loss of propulsion while driving. The engine did not completely shut off, but pressing the accelerator produced no power or acceleration. I was on the highway going about 80mph with traffic when it happened and left me stranded on the side of the very busy highway. The vehicle was taken to a Chevrolet dealership on September 18, 2026. Following an engine teardown, the dealership informed me that an engine bearing had failed. As of November 5, 2026, the vehicle remains at the dealership while GM determines whether to rebuild or replace the engine. The engine recall had reportedly been completed before I purchased the vehicle. I am concerned about the safety of this failure and whether the recall remedy adequately addresses the underlying defect.

Evaporative emissions purge pump failed at 18,473 miles. As the bumper-to-bumper warranty has expired GM refused to cover this repair. As this is a known problem with certain GM vehicles, the repair is covered for older model year out-of-warranty cars and for residents of other states (California, for example). This repair is covered by the emissions warranty in some states (California), but not Michigan.

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."

Catastrophic Engine failure - Chevy, Silverado 1500, Yr: 2023; Odometer: 33,183: On 8/16/2026 we were traveling down a busy highway towing our camper and the engine completely stopped, no propulsion, no warning lights, no check engine lights; complete failure; we had to coast to side of road. The only thing that indicated a problem is that we started hearing what sounded like marbles rattling, it wasn't loud but noticeable. We pulled over at gas station to check oil, even though we just had the oil changed for maintenance on 7/17/2026 (Odometer: 32,587). Everything checked out ok; however, the marble sound became louder; then within 5 minutes of leaving the gas station, we lost all engine propulsion; the engine completely shut down. Our safety was put at risk as we had no truck engine and were towing a camper on a busy highway; and had to try and coast to a safe location on side of road; miles away from home. We had to call a tow truck to come get us and unfortunately, they could not help us with our camper so then had to call our son to come with his truck to get our camper and us home safely. The tow company also had a difficult time getting the truck into neutral to tow. The truck was towed to our hometown Chevy Dealer. The dealer said that they were not going to diagnose the problem and instead are ordering a new 6.2 engine; same as the 6.2 that failed. We asked if this would fix the problem and they said there were no guarantees as it is the same engine with the same problem. Prior to this event, we received a recall in Sep 2025 and an engine inspection and oil change was performed on 9/12/2025 (Odometer: 25,751); we were told that our engine was ok. As of 9/3/2026; we have been without our vehicle for 17 days.

Main bearing failure at highway speed. Engine replaced by GM under warranty. Vehicle had the recall service done prior to the failure, the recall test and different oil was inadequate to predict or prevent this failure. Vehicle was serviced by the dealer for all oil changes on time.

Multiple times the truck has stopped running while driving. Once one the highway, once in an intersection, another time in a parking lot. It has not started when I have tried to turn it on. All the times I have called AAA. They have checked the battery and there is no battery issue. Twice AAA has come out, once the police have come and sat behind the truck to keep me safe. After about 10 minutes of the sitting with the truck off I can restart it and drive. Upon research, other Chevy trucks of similar age have a recall for a failed fuel pump module. This is the issue. If it is a known issue, and causing a dangerous situation it should be recalled on all trims of Chevy trucks. I will be getting this fixed, but don’t feel I should incur the $1,000 expense for a known defect.

Was making a left turn with a left turn street light green for me to turn across an intersection. Pickup stalled in the middle of the intersection and would not start. With the help of another person we manually pushed the pickup out of the intersection and onto another side street. I received an email at that exact time from General Motors showing a code of P129F which is the Fuel Pump Power Control Module. I am a [XXX] man stranded in 90 degree heat with no AC or shade to get under. My safety was put at risk in the above instance but more so if I had been entering IH 10 into traffic traveling 70MPH and my truck had just stopped running without any warning. This is a known problem as described in GM Service Bulletin 24-NA-139 with both the federal safety agency and DOT.
