We own a 1999 Volvo S70. While driving the car it started to surge while at a stop without and foot on the gas pedal at all. While trying to pull out from a stop sign the car had a mind of its own. It did what it wanted too without my controlling it. The gas pedal went up and down all by itself. The car then stalled and would not start and run. A check engine light came on and a ets light came on. Lucky we where not on a major highway and where able to pull over. We had to get a tow truck to bring it home. I called a Volvo dealer in our area. After some research on the internet I find out this was a problem in all 99 to 2001 Volvo's. A recall had been issued for this problem. The Volvo dealer will only upgrade a software issue. If the part { etm} fails they will not replace it. We never had a car that the gas pedal is controlled by this system. After getting out car back from the dealer the same day it did it again. We took the car back and even though the car meets the recall requirements they will not replace it the etm. Now we have a car that is not safe to drive. If this had happened on a interstate we could have been rearended or ran into someone else. Please help.
