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…

While driving at highway speed, the factory-installed serpentine belt on my 2023 Chevrolet Express 3500 (6.6L V8, approximately 24,000 miles, purchased new, factory-maintained per schedule) failed suddenly and without warning. The belt on this engine drives the water pump and other critical accessories, so the failure caused immediate loss of engine cooling and rapid, severe overheating while the vehicle was in motion in traffic. It also lost power steering assist, making the vehicle…

The OTA had the interstate lanes bottle necked down. Traffic was trying to merge. The van had already slowed down and moved into the thru lane closest to the median. The van was pushed off the road by a semi into the contrete barrier. The semi clipped the bumper on the front passenger's side. It was also hit on the driver's side rear bumper. All of this caused the van to hit the wall on the front driver's corner. The airbags did not deploy! The driver was slammed into the steering wheel hitting…

ABS Valve Body / Pump Harness chafed through brake hydraulic line near transmission crossmember. This resulted in a hydraulic leak and loss of brake pedal feel / partial loss of brakes. Fortunately failure occurred in the driveway--I had 4500 Lbs of sailboat trailer hitched to the van and was about to go on a long trip. Design issue. Wiring harness should not be located so as to chafe on hydraulic lines. This is not the first chafe related failure on this vehicle.
