“In august of 08 my 2004.5(new body style) Volvo S40 t5's engine began to make a high screeching noise at idle and the check engine light came on. It had 61,000miles and I brought it to the dealership where they diagnosed that it needed a new oil trap. The problem has not recurred. My wife's 05 S40 t5 has 58,000miles and the same problem has occurred in her's. There must be an issue with this vehicle.”

“My car was making a pumping noise from the rear of the car and the check engine light would come on. I took it to a local mechanic and they informed me of the pem recall/extended warranty. I took the car to the Volvo dealership to have repaired and they said the pem was not the problem and that it was a fuel pressure sensor and possibly the fuel pump itself. I declined the repair and exactly 2 weeks later the car failed to start. I had it towed to my local mechanic since I live 70 miles from the Volvo dealership. …”

“Engine failure. Car stalled while driving on highway. Car was towed to wynn Volvo. Was told that the belts broke, leading to the breakage of the timing belt, located inside the engine, resulting in major damage to the engine. Was given a quote of $5600 to repair. The car has 63000 miles and the manual does say that the belts need to be replace at 125 thousand miles. The services suggested prior to this does not include any of the belts being replaced.

“I have a 2005 Volvo S40 2.4i with about 47k miles and I am having problems with the A/C. I live in houston (tx) where it gets very hot so I have to have the A/C on constantly. When I first turn the car on and drive off, the A/C starts cooling and working just fine. However, when it is 90f or above, the A/C begins to blow warm air after a few minutes. When that happens I have to turn it off and back on a few times to get it working again but it only works for a few minutes before I have to repeat on/off ritual. …”
