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.
Engine was at idle had pulled into gas station . Alarms went off check engine light came on, stable track error, multiple tones. After 20 seconds engine stalled. Would not crank. After talking to people and couple tries fix took to dealership as it was diagnosed to be the engine control module shorted. I had gone thru rain earlier and a couple storms passed thru while at station and eating. Dealer replaced engine control module and programmed it. This could of happened while driving and would of lost engine power and power steering. Since just module replaced and ben told it is know to short out when wet it could happen again.
The contact owns a 2012 Chevrolet Express. When the brakes were depressed and released, the vehicle began to shake violently. The contact mentioned that the stabilitrak activated independently after being turned off without warning. The vehicle was taken to dealer. The technician was unable to diagnose the failure. The manufacturer was not made aware of the failure. The approximate failure mileage was 47,000.
