2024 CHEVROLET SILVERADO 1500 Complaints

The primary failure is in the electronic transmission control system and engine wiring harness assembly, specifically throwing diagnostic trouble codes P0700 (Transmission Control System Malfunction) and P0717 (Input Speed Sensor Circuit No Signal). The authorized dealership identified a critical issue with the engine harness chafing, but their subsequent repair attempts have failed to resolve the recurring powertrain failure. The complete vehicle and all affected components are currently parked and fully available for immediate physical inspection at my residence upon request. While operating the vehicle at highway speeds, the powertrain abruptly loses throttle response and forces itself into a severe, uncommanded "Reduced Power / Limp Mode." This creates a severe safety hazard by instantly dropping vehicle velocity on active interstates and high-speed roadways, leaving the vehicle unable to accelerate out of harms way or merge safely, placing myself, my passengers, and surrounding motorists at immediate risk of a high-speed rear-end collision.The malfunction has been repeatedly confirmed and documented by authorized GM service agent Rountree Moore Chevrolet (Lake City, FL) across three separate service visits. The dealer confirmed the active trouble codes and attempted various repairs (including Transmission Control Module reprogramming on 04/24/2026, engine harness chafing repairs on 05/19/2026, and auxiliary fluid/battery adjustments on 05/21/2026). The persistence of the failure confirms the dealer has been unable to successfully remedy the defect. To date, the vehicle has only been inspected and worked on by the authorized dealership's factory-trained technicians. It has not yet been involved in a collision requiring police or insurance representative inspections, nor has a corporate field engineer from General Motors inspected it outside of the local dealership level.The failures are consistently preceded by an illumination of the dashboard Check Engine

Tailgate opened on its own while driving down the interstate. Since then, anytime I open a door or use the drivers door to unlock the truck, the tailgate drops.

No warning lamps, have not brought to the dealer, there is a recall for this issue, but my VIN doesn't match

I was driving home from work, and dash warning sign came on and told me to start engine. I was currently driving at approximately 60 mph. When i came to blinking red Light i went to accelerate and truck was unresponsive. it would not accelerate and engine was off. I went to start engine and it just cranked with no start. I used onstar to get a tow truck. I was broken down in the middle of an intersection and had to wave traffic around me for 1hr 45 min. Finally tow truck came and took truck to local chevy dealership. Upon inspection they stated that it needs a new engine. I had the truck in the chevrolet dealership in feb 2026 to have the 6.2 recall done, they performed the full recall and said everything looks good. truck has approximately 60k miles on it. it failed a few months after inspection. They stated they have ordered a new engine and it would be approximately 4-6weeks minimum. Truck is sitting at the dealership

While exiting a highway via an off-ramp, the vehicle experienced a sudden mechanical failure consistent with internal engine/bearing failure. During deceleration on the off-ramp, the engine began to shudder violently and immediately lost power. The vehicle was unable to maintain normal operation and became unsafe in an active traffic environment. After coming to a stop, the engine would not restart and the vehicle was completely inoperable. There were no prior warning signs or alerts before the failure occurred. The issue developed abruptly while the vehicle was in motion. The vehicle required towing and dealer inspection. Diagnosis confirmed internal engine damage / bearing failure / engine seizure. The repair required engine replacement This failure is consistent with widely reported issues involving GM 6.2L V8 engines (model years 2019–2024) experiencing bearing failure and catastrophic engine damage. The same failure characteristics appear to be present in this vehicle. This represents a serious safety concern due to the sudden and complete loss of engine power and inability to restart the vehicle while in a traffic environment, creating risk of collision or roadway obstruction. The vehicle had approximately 65,000 miles at the time of failure.
