“I have a 2001 Volvo, model S40. During the last six months, I've experienced a stalled car engine -- especially when the car is idling at a stop light. When the stall happens, I must floor the accelerator to restart the engine again. This problem is the same as those already reported to the NHTSA for other Volvo models for the years 1999 to 2001.”

“I own a 2001 Volvo S40. In early april 2005, my vehicle was diagnosed as being in need of oxygen sensors, which was the reason for my check engine to be activated. The problem is that my car had approximately 25,000 miles on it. As of mid october 2005, the check engine light has been reactivated and the vehicle was recently diagnosed at the Volvo dealership as needing new oxygen sensors-again. Currently, my car has 32,000 miles and is going on its third set of oxygen sensors. The parts and labor that are required to fix the problem are truly expensive. …”
