general problems of the 2002 Volvo S60

I was involved in a car accident in bronx, NY on 8/16/2017 that caused severe damage to my 2002 Volvo S60. Thankfully, I was the only one in my car. I had just left my last destination, moving slowly and driving straight for a short block or so, when my 2002 Volvo S60, with an odometer reading of 45,000 miles, began to accelerate out of nowhere and race - all on its own. I tried braking (foot and hand) but it was too sudden and neither could slow it down. The car accelerated out of my control, jumped the sidewalk and plowed through a fence before coming to a stop. I'm still shaken, thinking of what could have happened, but thankfully there was no one else involved and no one was in front of me or walking by. While this is shocking and surprising to me, I believe this is a known safety malfunction on certain models of Volvo cars. I have read that other driver's have complained to the company about a racing/slipping transmission before, which suggests that Volvo has been aware of this. For some time. There are so many situations in which this type of malfunction can easily be fatal so I am treating it as an impending disaster for others that needs to be acted on urgently. I am seeking your assistance to investigating this as quickly as possible so that you may have a chance to preserve the car for added testing if necessary. I have provided all the pertinent information that I possibly can.

The car continues to have shift flares and slippage when shifting up from 1 to 2, 2 to 3 or shifting between the same gears.

From around oct. Of 2011 I have been experiencing trouble with my throttle body or as Volvo calls it 'electronic throttle module'. These problems include but are not limited to, stalling at freeway speeds, rough starting/ not starting at all, reduced engine performance not allowing for safe speed to be maintained, costly repair work with no improvement, and bouts of self accelerating at stops with parking brake and foot brake engaged. I have research a Volvo recall/ warranty extension for a defective throttle body, contacted Volvo customer service only to get the run-around. Various web forums encourage owner experiencing these problems to file complaint with NHTSA to help come to a resolution.

I was stuck in high way traffic for about 45 minutes, once the traffic cleared I tried to accelerate but could not, I was afraid I was going to get hit because I could not get my vehicle up to a safe speed (the vehicle went into limp mode). I was able to get the car to at least 50 mph to get it home. This now happens within approx 1-2 miles of driving. Due to the hi cost of repairs for this vehicle I had the diagnostics done first (cost $90. 00), the result was a bad mass-air sensor and faulty throttle position sensor. I had the mass-air sensor replaced at a cost of $140. 00, I then had the throttle positioning sensor cleaned ( this is what the dealership will do first, because of the hi cost involved in replacing the throttle body & programming it) at a cost of $180. 00. The cleaning did not work and therefore the throttle body needs to be replaced and programmed at a cost of $800. 00.
