2020 Chevrolet Express Cargo 3500 recalls

The vehicle is experiencing an under-chassis manufacturing wiring harness restriction (Connector X185) that was installed too tightly from the factory, dropping the 5-volt reference power circuit down to 0 volts under load. This intermittent electrical failure completely starves the fuel pump, causing the fuel loop pressure to drop to a dangerous 43.5 PSI while driving (GM factory specification is 55–100 PSI). This electrical breakdown simultaneously chokes the fuel tank vapor loops, causing the fuel tank pressure to spike to an extreme -1100 vacuum pressure parameter. This results in severe engine hesitation, random vehicle starving of fuel, an abysmal 9.9 MPG average compared to the 13 MPG

The contact owns a 2020 Chevrolet Express. The contact stated that while driving 60 MPH on the highway, the vehicle lost motive power and shuddered abnormally, causing the vehicle to decelerate to 40 MPH. The vehicle was pulled over and restarted; however, the failure persisted. The failure recurred while driving at 40 MPH on several occasions. An independent mechanic was unable to determine the cause of the failure. The vehicle was towed to a dealer, and the contact was informed that the VIN was not associated with NHTSA Campaign Number: 24V839000 (POWER TRAIN); and refused to provide a diagnosis without a visible fractured part. The vehicle was not repaired. The manufacturer was notified o

The contact owns a 2020 Chevrolet Express. The contact stated that while driving at 60 MPH, the vehicle experienced a sudden loss of power and was shuddering while driving on the highway. The vehicle was pulled over to the side of the road and restarted; however, the failure reoccurred shortly afterwards while driving at 15 MPH. The contact stated that the failure had occurred on several occasions. The vehicle was taken to an independent mechanic, but it was not diagnosed. The vehicle was then driven to a dealer, where the contact referenced NHTSA Campaign Number: 24V839000 (POWER TRAIN); and associated the issue with the recall; however, the VIN was not included in the recall. The vehicle w

While driving this cargo van, the driver stopped in traffic to make a left hand turn. In the middle of the turn, the vehicle stalled out and would not immediately start, exposing the vehicle to nearly being hit by the oncoming traffic. When the vehicle eventually restarted, and later brought to a GM dealer for repair, it was discovered that the main ground cable had completely deteriorated. In our fleet of 15 GM vehicles, this is now the SEVENTH vehicle that has needed this main ground cable replaced. This is a serious issue that needs to be addressed.
