Chevrolet Silverado 3500 stalling problems

Filed Aug 24, 2026 · Fuel system · FL

The high pressure fuel pump failed and sent metal particles throught the fuel system. All fuel components except for the injectors are available. The engine stalled while driving at speed forcing me to stop and call a tow truck on the side of the road. Mileage at failure was 81340. Preston hood Chevrolet diagnosed the HP4 failure and replaced the entire fuel system, noting metal contamination in all areas. The component has not been inspected. The truck had a slight grinding noise when shifting into 4th on throttle. Took it to a firestone and the techs noted its possibly just shifting hard, no issues found. The grinding noises ultimately was the HP4 failing. No warning lamps or other indications of a problem were present prior to the catastrophic failure.

I was driving down the XXX Expressway Sunday, XXX, with my children in my vehicle. This is a very heavily traveled highway in [XXX] with heavy traffic. My 2024 Chevy Silverado 3500 Diesel HD Truck with 25,500 miles suddenly started throwing multiple codes, lost power, and steering. Fortunately I was able to "roll into" the emergency lane while muscling the steering in that direction and engaged the emergency brake. My other son was following shortly behind me in his vehicle and pulled over to assist us about 30 mins after my truck was sitting stalled in the HWY. He parked his truck behind mine, put on his hazards, and we were transferring gear from my truck to his truck. At this point my 2024 Chevy HD Silverado Diesel started rolling back on it's own and nearly crushed my son's friend. The parking break was on and it suddenly released on it's own. It took 3 grown men to stop it from crushing my son's friend. The force was so strong that when he lifted his hand to try to stop the truck from rolling, it broke the right rear tail light. He could have been crushed between our two trucks from this situation. I have never been notified by GM of any recalls, however, the truck had to be towed to Ferman Cheverlotte service on Adamo Dr, Tampa Fl and is currently sitting on their lot. I was told by the service tech Michael Stevens that the vehicle had several open recalls that they would address but did not offer any information about what could be wrong. After searching online, I found that GM IS aware of this issue and sent several service bulletins about this exact problem. I had contacted the Ferman service center the week before to bring the truck in because the AC was out and made an appointment for service on Tuesday. The day after I made the appointment my batteries died and had to be replaced by AAA.It is disturbing to know GM and FERMAN Service centers are aware of this safety issue on these HD trucks and never informed me, the consumer.

Email Subject I am reporting a serious safety-related defect involving sudden and complete vehicle shutdown while driving in a 2024 Chevrolet Silverado EV RST. Component/System Involved: The failure appears related to the 12-volt electrical system and associated vehicle control electronics. When the vehicle detects the 12V battery as dead or critically low, it immediately disables propulsion and control systems. The exact failed component is UNKNOWN. The vehicle is available for inspection upon request. Incident Description: This failure has occurred twice under similar conditions (ambient temperature approximately 25°F). On November 28, 2024 and again on January 2, 2026, after driving approximately two blocks at low residential speeds, the vehicle abruptly and completely shut down while in motion. In both incidents, the shutdown was immediate, without warning, and accompanied by a loud thud and an extremely abrupt stop. Safety Risk: In both incidents, the vehicle became completely immobilized in the roadway. I was unable to steer to the side of the road, restart the vehicle, or shift it into gear to move it out of traffic. This created a significant risk of collision. A similar failure at highway speeds could result in a severe or fatal crash. Warnings or Prior Symptoms: No warning lamps, messages, alerts, or other symptoms appeared prior to either shutdown. Problem Confirmation or Reproduction: The issue has occurred twice under cold-weather conditions. Inspections: After the first incident, the 12V battery was inspected and no issues were found. Following the second incident, the vehicle is currently being inspected at a Chevrolet dealership. No police or insurance inspections were performed. This behavior suggests the vehicle lacks a fail-safe or degraded-operation mode for 12V system failure and instead performs an immediate shutdown while in motion, which may represent a serious safety defect warranting investigation.

We bought a Chevrolet Silverado from 2023 as a new car in October 2024. It is an imported vehicle, as we live in Germany. After 7146km we broke down on the highway on [XXX] with engine damage. There were no signs or warnings beforehand. The Chevrolet simply stalled while driving and indicated that the start/stop button should be pressed. However, this had no effect. The whole vehicle came to a standstill. Not even the wheels were still rolling. A call to the seller (GeigerCars in Munich/Germany) immediately revealed that it was probably engine damage, as the problem is known. The vehicle was then towed to the seller's workshop and has now been there for over 5 weeks without spare parts, as according to the seller these are not supplied by GM. We have not yet received a rental car or anything similar and have to rent a car every week at our own expense. We have not received any help so far. A lawyer has already been called in.

Vehicle regularly stalls while driving, going down hills and any random time at highway speeds, while in traffic, while stopped at traffic controls. This problem happens repeatedly and is apparently related to the “pump mounted driver”, which is prone to failure due to inadequate design for the use and environment. It creates random failures Of the pump to deliver fuel.

Probable High Pressure Fuel Pump (CP4) failure resulting in the vehicle stalling without warning. This event has not yet occurred, however due to the high number of vehicles involved in the Stellantis recall which are using the same CP4 pumps which are known to fail, I am scared to drive my truck as the CP4 pump may fail at any time. I have spoken to MANY other GM truck owners who have experienced this failure and it has cost them tens of thousands of dollars. Please open a recall for the CP4 High Pressure Fuel Pump for 2011-2016 GM trucks using this HPFP. Thank you,
