“Vehicle intermittently stalled while driving down an incline or slowing down to a stop position. Vehicle had been to the repair shop on five separate occasions, and at the dealer once, however, and neither of them could resolve this problem. When turning on the headlights the srs and ABS light illuminate. The tachometer performed erratically. The alternator assembly was replaced. The vehicle's engine noise was caused by a bolt in the water pump which was too long and hit against the pump.”
