Chevrolet Silverado 1500 won't start problems

Filed Nov 5, 2026 · Engine · FL

I parked truck in driveway and an hour later it would not start. It was towed to 87 Garage where they installed new starter. Mechanic called and said starter was not problem, then engine seized. Need a new engine. This could be catastrophic if it seized while driving. GM tells me take to dealer an pay diagnostic fee to help. I’ve read a recall maybe coming issue by the federal safety agency after GM hands over all of these reports on 13 November 2026. My engine seized 31 October 2026. I’m waiting for new engine replacement cost estimated 15-20,000.00 from 87 Garage.

Truck would not start - it left me stranded. The main body to engine ground strap had rotted off. I found there is a Chevrolet Customer Satisfaction Program (N252515590) for ground straps rotting for the same make/model/year as my vehicle, but for some reason mine isn’t listed by VIN number in the program.

I took my truck and atvs from Ohio to Michigan for vacation. We took my truck out. We swerved to miss a deer. Pulled over to check everything out and the truck shut down and would not start. Called roadside assistance, they towed vehicle to a Chevy dealer. Dealer calls me later that afternoon telling me the engine locked up and needed replaced. The truck had 5,800 miles when this happened. We were also traveling at low speeds. If this had happened on the freeway it may have caused a serious accident and may have resulted in injury or loss of life. Since they replaced the failed engine with the same engine I am concerned it will do this again and have no confidence in this vehicle.

The vehicle's power steering went out mid drive on the road after being driven about 2 miles. I was unable to turn the wheel. I attempted to restart the car at that point is when the engine would not start. The truck did not move in the middle of traffic. This is caused by some electrical problem. The dealer does not know what the issue is and they could not duplicate the issue. It is the second time it has happened to me.

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.

The specific cause has not been identified. On XXX6, my 2025 Chevrolet Silverado 1500 Custom LT Trail Boss unexpectedly rolled away while parked and unoccupied, striking another parked vehicle. The truck remains at Modern Chevrolet and is available for inspection. GM/ESIS opened a safety and product liability investigation and is arranging inspection/data retrieval. I parked at Walmart in [XXX], shut the truck off, exited, locked it, and walked away. Shortly afterward, I heard a sound resembling the key-fob-left-inside warning. My key fob was in my pocket, so I returned and saw the truck moving with no driver. Another person and I tried to stop it. I entered through the driver’s door and pressed Start/Stop several times, but it would not start while moving. It continued moving and struck another parked vehicle. Vehicle dropped off on XXX and Modern Chevrolet could not reproduce the incident or identify the cause. The service advisor stated it “came out of gear but don’t know why” and escalated it to GM. GM/ESIS plans to retrieve SDM/airbag data, and I requested any Tech II/MDI scan data. No warning lights, messages, or chimes were observed during the incident. I did not see/hear “SHIFT TO PARK,” and I was able to lock the truck with the key fob outside. In a later controlled test, I left the truck in Drive and shut it off. It displayed “SHIFT TO PARK” and sounded a warning chime. Opening the driver’s door also produced a key-fob-left-inside-type alert, which did not occur on XXX. The truck did not automatically shift to Park or engage the electronic parking brake and slight movement was felt during the test. No further testing occurred by me after XXX. I have also experienced infotainment freezing after software updates and random electronic parking brake application when shutting off, and remains engaged after restart. The truck received an oil change/tire rotation at Modern Chevrolet on XXX. Cause still remains UNKNOWN. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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."

Traveling on interstate highway at 70 mph when the truck engine went to idle and transmission tried to go into park. The dash just flashes "service transmission" and and other warnings. Engine still runs but can't shift out of park. Shifter is not responding to move the truck. Engine can't come off idle. Turn off engine. Power button will turn power on or off but won't crank engine. 4 ways flash for awhile with dash flashing then everything go blank. All electric power is lost for awhile and then dash starts flashing and 4 ways start flashing for awhile. This cycle keeps repeating. Truck has to be loaded on a truck to tow away. This is the 3rd time is has done this problem but at lower speeds before. Dealer can't find the problem yet.

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

The transmission it erratically shifts and has a roaring sound. I also says shift to park when it is in park. It wont start when it is cold it just cranks and cranks it has since i bought it. Well when my kids and I are going down the road and the transmittion randomly starts up shifting or down shifting and whenit goes out its gonn lock up probably where fever we are. as for the starting thing when its cold its isnt the ideal to have to go build a fire in the garage just to get my truck to start during an emergency. I have had a garage hook it up to a computer to see if it was throwing any codes. It wasn't except a brake sensor. I bought this truck 2 years ago and have nothing but trouble with it shifting and and the dash always says shift to park. this is one of the worst Chevrolet trucks i have ever bought. it only has around 70000 miles on it. I had the truck about 3 month when the transmittion issue started. It has never started when it was cold out side the whole time I have owned igt.
