Car Stall problems of the 2010 Chevrolet Express

This vehicle has had multiple incidents of cutting out and stalling causing loss of steering and brakes, and just before it completely shuts down it will power back up. In April 2011 an operator stated "intermittently when making a left hand turn at approx. 10 - 15 mph with acceleration the traction light comes on and van cuts out for a few seconds like someone shut off the key, it powers most of the way down and then will come back on its own. " during this time the steering and brakes are compromised. In November 2011 an operator stated "powers down while operating, brakes lock up and power steering locks up, van pulls to the right in corners, seems to be abs with no brakes applied in corners/" in November 2012 it was reported from 3 different operators that the van cut out and each of them almost lost control of the vehicle. Reports included going 40-45 mph into a left hand curve, the engine suddenly started to lose power and there was a loss of steering and brakes, and the right hand tire went into the ditch on the right. Another operator said the engine died and the vehicle almost went into the ditch, the vehicle was cold and they had just begun their trip. The 3rd operator said the wheel locked up at 40 mph within the first 1/2 mile. Most of these incidents seem to happen within the first 3 miles of operation.
