Purchased vehicle used several weeks ago. While performing fine during test drive, within hours vehicle developed issue where it attempts to surge forward while braking (at stop light, in driveway, etc.) which has almost caused numerous accidents. Other times, when pressing the gas pedal, the car hesitates and almost stalls before accelerating, causing dangerous conditions at highway speeds. Brakes inspected and are perfect as is fuel pump, fuel injectors, engine, etc.; mechanic suggested that this is related to a recall volvo issued in 2006 regarding the electronic throttle module. Volvo informed me that it is no longer honoring this recall.

Upon accelerating up the hill of my street, today, august 16th, 2011, my car, a 1998 volvo s70 , sped up, unnaturally, close to the top . I had just driven out of my driveway, as I back into it always, and proceeded up the hill. As usual, the automatic transmission shifted down as the car approached a steeper portion of the hill. When braking for the stop sign at the top, I noticed that the engine was racing. I was unable to stop fully at the stop sign, and after going around the corner to the right, I pulled the floor mat away from the accelerator pedal. My left foot was now firmly planted on the brake pedal, as well as my right foot quickly pumping the accelerator pedal , all in an attempt to have the gas pedal unstuck, which it didn't. It just made the car engine continuously race even more. The RPM's increased also the more that the engine raced. Unable to fully stop at the next subsequent 2 stop signs, on a straight away, and my left foot to the floor with the brake pedal, I finally decided to place the car in neutral, the engine racing at what seemed a very high rate of speed by evidence of those RPM's. I continued to pump the gas pedal,with the car in neutral, my left foot on the brake, when suddenly the racing ceased, and the RPM's came down to an idle, just below 1000, I believe. I then proceeded to the side of the road, and stopped. After a bit, I placed the car from neutral into park, and then again shifted the automatic transmission into drive. I began moving down a hill by mere idling speed. I was careful, just coasting now, not to initially place any pressure on the accelerator as I proceeded in drive. I came to a stop at an intersection, for a red signal light, and when it was green, I drove back around a large city block to my driveway. I backed into my driveway with no further issues of sudden acceleration during the final distance driven. This has happened 2 other times recently when setting cruise control going up a hill.

In mid-december the car started but ran rough and lacked power. Previous to that it ran fine; since then it has had various intermittent problems related to acceleration. Sometimes the engine runs rough and lacks power. Other times the engine runs fine but the car does not respond to accelerator input to increase speed. Sometimes the car stumbles but accelerates adequately. More often the car will accelerate to about 20 MPH and not increase speed beyond that irrespective of accelerator pedal pressure. After a few seconds the car will suddenly accelerate normally. Replacing the throttle body module corrected the problem. This part is subject to a the federal safety agency agreement with volvo that requires volvo to replace the unit free but the dealer refused to do that and charged me for the repair.
