2024 Chevrolet Silverado 1500: won't start

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.

2024 6.2L Silverado Trail Boss, engine failure at 22k miles on 4/13/26. Dealer confirmed the failure (not sure which bearings seized since engine has not been torn down yet, was either crank or rod bearings) and ordered a new engine 4/14/26. I was driving on the interstate and the engine started lightly shuddering during acceleration, showing some loss in power and shifting oddly but no check engine lights and nothing too alarming to immediately pull over. After several miles of this, the engine started to emit a loud metal on metal squeaking/scraping sound when on the throttle but stopped when I would back off the throttle. About a mile later, the truck just shut off at 70mph and went to neutral as I was about to get off an exit to evaluate the issues. Dash said push button to restart as I was coasting, but it wouldn't restart so I put on my hazards and pulled to the shoulder of the highway. Once stopped, it automatically shifted to park and would not crank or allow me to shift to neutral. Flatbed was called and brought it to the dealer. Side note: The truck passed the Pico test 1/15/26 at 20k miles and was sent on my way with the thicker 0W-40 oil. Oil was changed every 5k miles and ran 93 octane.

Summary of Incident: On March 28, 2026, while traveling at 70 MPH on the Florida Turnpike, the vehicle suffered an instantaneous loss of motive power. The engine died abruptly with no warning. Upon reaching the shoulder, the electronic transmission locked, refusing to shift into Neutral or Park. The engine cranks but will not start. 1. Component Failure & Availability: The exact component is currently unknown, but the failure involves the Powertrain, Fuel System, and Electronic Transmission Control. The vehicle is currently at an authorized dealership and is available for inspection by the manufacturer or the federal safety agency upon request. 2. Safety Risk: The sudden loss of power at highway speeds created an immediate risk of a rear-end collision. Because the electronic transmission locked and would not allow the vehicle to be shifted into Neutral, it became a fixed object on a high-speed shoulder. It could not be pushed to a safer location, increasing the risk of a secondary accident. 3. Problem Reproduction: The vehicle was towed directly to an authorized Chevrolet dealership. As of this filing, the dealership is in possession of the vehicle, but the failure has not yet been reproduced or confirmed by a technician as they are awaiting formal diagnostic commencement. 4. Inspections: The vehicle was inspected by a roadside towing professional for transport. It is currently at the manufacturer’s authorized service center awaiting a formal diagnostic inspection. No police or insurance inspections have occurred. 5. Warning Symptoms: There were no warning lamps, "Check Engine" lights, or messages prior to the failure. No symptoms like rough idling or unusual noises occurred. The vehicle performed normally until the moment of total power loss.

I had a engine failure in my 2024 Chevy Silverrado Trail Boss1500. I had just exited off the highway and came to a complete stop at the stoplight. When the light turned green, I hit the gas pedal and I did not move. I looked down at my gear shifter and noticed the truck was in park (I did not shift the truck into park). I tried to put the truck into drive and realized the engine was not running. I tried starting the truck and it would not start. The truck would crank, but would not start up. I tried this several times with no luck getting truck started. I even tried to put the truck in neutral to get the truck out of the middle of the road and could not get it neutral to move it. I called chevy roadside to tow it to the dealer. The dealership called me on tuesday and said the engine had blown because of a bearing failure and engine needs replaced. Also, they have not let me know approx time I will get my truck back. They claim there's a shortages of engines on the 6.2 liter engine.

Hi - I'm filing a complaint against Chevrolet with the federal safety agency's Office of Defects Investigation. I purchased a brand new 2024 Chevrolet Silverado in Dec of 2024 from a dealership in MA. I've had the truck for only 2 months and only a couple thousand miles. I was in Quebec with my family for a ski vacation and we were driving back on [XXX} when my truck suddenly started making loud engine noises. I was able to get off the interstate to a gas station and then the truck turned off and would not start again. I had the truck towed to a Chevrolet dealership in Granby, Quebec. There was no warning or alerts before the engine failed. This is a known issue that the federal safety agency is currently investigating, it has to do with the 6.2L V8 engine in GM vehicles from 2019-2024. The engine is seized and cannot be repaired, truck needs a new engine. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

He instructed me to drive around I said it will be not go into motion. After 15 minutes I checked the status on my phone and it did not display anything wrong so I went ahead and turned it on and drove it to the service center but once again it would not accelerate and shock vigorously. Once in the service line it turned off and did not stay on. Dealership ran diagnostics he mentioned cylinder and piston but they need to run more test. He called me back 2/14/25 asked if I had taken it to the dealership where I bought since purchased I said no it’s brand new, it looks tampered with . Called me back again and said this vehicle had a motor recall and a technician at Riverside Chevy worked on it and all the components are not connected we can work on it it need to go back to them and they need to explain what is wrong. He sent them a video of the tech looking at everything that was wrong. Truck was towed to Riverside Chevrolet [XXX]. This is a brand new vehicle that only had 17 miles when purchased by me ,at the moment it has 709 miles non of the components of this vehicle are new anymore they are either melted or rattling inside ,the gas tank sounded like empty cans rolling around, the transmission would not make the vehicle move. It is called lean mode if I’m being correct the vehicle was protecting it self from what I don’t know, so yes I feel it is unsafe and would like your help with this vehicle matter at your earliest possible conve INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5

Subject: Engine Failure – 2024 Chevrolet Silverado 1500 (6.2L V8 •VIN: [XXX] Issue Description: While driving on [XXX], I noticed the transmission would downshift but not upshift. Within seconds, a warning appeared: “Oil temperature high, idle engine.” I began merging onto the shoulder, but before I could get there, the engine shut off completely, and the transmission shifted into neutral. After coasting to the shoulder, the transmission shifted into park on its own. Failure to Restart & Electrical Issues: I attempted to restart the engine, but it would not turn over. The dashboard, radio, and electronics turned off for a few seconds before coming back on, but the engine remained unresponsive. Towing Difficulties & Roadside Assistance Failure: GM Roadside Assistance said no contracted towing companies had the equipment to tow my truck because it would not shift into neutral without the engine running. I had to find and pay for a tow truck myself, with no guarantee of reimbursement. Dealer Response & Repair Delays: My truck has been at the dealership for days, but they have not started repairs due to technician shortages and a backlog of work. They stated: •Manually cranking the engine is nearly impossible. •The starter is not strong enough to turn it. •Repairs could take months. Loaner Car & Additional Hardships: Per the GM warranty, I received a loaner car but must return it every 500 miles. Since I commute 160 miles per day, I must frequently exchange it, causing major inconvenience. Safety Concerns & Requested Action: This sudden engine failure on the highway was a significant safety risk. Given that the federal safety agency is investigating failures of the GM 6.2L V8 (L87), I believe my case is related. GM should issue a recall or extended warranty for affected vehicles.

I arrived at work and i got to a parking space and all the sudden the truck shut off and wouldn't not start back up. Upon arriving to work i rolled down my window and heard a long banging noise coming from the engine Aswell as a whining noise. I attempted to start the truck up and you hit the start button the truck just keeps whining and never starts up.

Overall, i could have been in serious car accident for because the engine just shut off on the highway, this happened with no warning or anything, the check engine light was NOT on before this happened.
