“The battery light came on suddenly and the power steering went out making it extremely difficult to steer the vehicle. An accident was narrowly avoided. We replaced the battery, alternator, and serpentine belt. The problem resolved for over 6 months, then reappeared. It starts with no issue, is charging properly, the serpentine belt is intact. The power steering will come on and go off sporadically, the only warning being the battery indicator on the dash that comes on first. This creates a substantial hazard and risk as the steering is severely impacted with little warning.”

He was able to reproduce the same condition where he was able to get the minivan to lose power when changing lanes. He STRONGLY advised that we should have the vehicle towed to the dealer as he felt that it wasn't safe to drive due to this. I feel that…”
