“I have Volvo S40 2000 which I purchased in october 1999. I brought my car to service regularly, it was serviced while in warranty by the royal motor sales who sold me this car. On the second service I have been told that my rear brakes completely worn out and they have to change not only brake pads but also rotors and something else, I ended up paying $1000+ for that service . …”
NHTSA complaint #10043536, filed 2003-10, 8,000 miles“A slight squeaking or squealing noise could be heard from under the hood of the car, no visible defects apon inspection. The sound was the water pump failing. As I was taking the car to the mechanic the water pump failed (ceased) and caused the belt driving the water pump to snap. The water pump was driven by the timing belt. I am told that when the timing belt snaps that serious damage occurs to the engine. I cannot understand why a failure of such an ordinary part can cause such damage. Volvo stated that the repairs can run from 3-6 thousand dollars. …”
