My vehicles High Pressure Fuel Pump failed causing the vehicle to shutoff while driving. In addition, due to the engine shutting down while driving, the power steering quit working causing me to not be able to steer the vehicle. Thank you
The CP4 pump failed while driving causing vehicle to stall. Upon failure, lost power to steering. Luckily we were on an access road for a rest area and not yet on the interstate. This resulted in a 14.5 thousand repair. No prior warning to pump failure. GM has recently settled a class action related to this pumps failure and has never recalled trucks with this pump to avoid failure.
