general problems of the 2000 Volvo S80

I want to make you aware of a very serious car accident that my mother had on 9-5-18. She was driving her 2000 Volvo S80 when her car began to accelerate on its own. She was not able to control the car. My mom had her foot on the brake but that did not stop the vehicle. Unfortunately, at that point the car was out of control hitting and banging up all the cars around it. Then the car finally smashed into another car stopping the out of control car. My mom was seriously hurt and taken to the hospital. She had emergency surgery to repair her aorta that tore from the crash. She also broke her sternum. I am devastated by what happened to my mom. I feel that it is extremely important that you and Volvo are made aware of this tragic situation that occurred by this Volvo S80.

Driving in the city and when trying to stop on a traffic light the brakes became hard and engine was not running well. When I tried to drive off in the green light the speed control of the gas pedal was very chaotic. I got a message of engine system service required. I took the car to the local Volvo dealer and he diagnosed a faulty throttle etm asking 2000 $ to replace. After researching I found that there was already a recall on that by Volvo and when I asked the dealer he said that this was true but my car was more than 10 years old ( although he could have informed me about that in the first place). He informed me that a software service on the etm of my car was done in 2006 ( after the recall?) but this did not fix the problem as apparently the problem is with the etm design ( faltering potentiometer). This car is very dangerous and it will probably go to the junkyard, but we should be concerned by all Volvos remaining on the street with faulty etm's, which the numerous complaints filed at NHTSA show.

I was driving along a busy street, when I came to a stop sign the brakes where hard to push, when I finally stopped the car, you could still fill the car trying to move forward I took my foot of the brakes and the car sped up on it's on reaching close to 40 mph again I was barely able to stop the car do to a stiff brake pedal. I put the car in park and shut it off, once I restarted the car it was sputtering and wouldn't idle correctly every time I put the car in gear it would shut off now I'm getting an error message that says service engine system urgent.

I purchased a 2000 Volvo S80 in Dec 2010. Several months after purchase I noticed a hissing sound coming from under the dash near the fire wall. The sound is coming from the brake booster. This has caused weak brakes. Sometimes when you push the brake pedal it goes to the floor and the brakes have to be pumped to stop the car.

My wife left for work & got to the end of the driveway & had no brake assist ie very hard pedal. This occurred without warning(no warning lights,etc). She parked the vehicle&took another to get to work(rn). I later drove the car,brakes worked fine. The next day I drove it again & no power brakes.

The vehicle experienced problem with the brake system. The dealer stated nothing was wrong with the brakes . Please provide any addition information.

In October 2001 while driving at night headlights went off. The following day while crossing the street the car stalled. Approximately ten minutes later was able to start the car, and at the same time headlights came on. Car was under warranty, and the mechanic repaired the throttle body & gasket. In June 2004 car stalled again. Replaced sway links and program down load $338. 19. In December 2004, car staled on the road again. It was towed to the repair shop, they replaced the throttle body, mass air flow, mfi module- at cost of 2098. 96. The contact did not take this car on any longer trip. Due to stalling on the road, frequent loss of headlights and numerous other mechanical problems the contact believed this car was unsafe to be on the road. 11-16 e-mail ; first time the car would not respond to the accelerator pedal. Stopped turn the car off and tried to restart it again. After few attempts the contact was able to restart the car. The right door mirror failed and the abs control module was replaced.
