My Volvo S80 2.9 was turning a corner when the serpentine belt came off and the car stopped. The Car was towed to the dealer who had it for ten days and called last night to say the the car had hit something and which had forced something- a tube?- into the timing belt which caused the belt to jump and the valves to be bent by the pistons. He said the factory re told him this because it had happened to others and he could see scrapes on the undercarriage. We are going to examine the car today. We cannot remember hitting anything. We did have a problem with the crank seal which was repaired earlier. Dealer says my warranty or extended warranty will not cover and I owe him for repair and loner which would have been free if the repair would have been covered. Anybody have similar problems or thoughts- I'm ready to sell the Volvo and buy something else.
