My 1999 Volvo S80 simply decided to stall while I was merging into traffic. I was able to avoid an accident. A message came on the dash that stated that I needed an urgent service visit for my emission system. The Volvo dealership charged me $1,000 to replace the electronic throttle. A second defect of this car is a leaking fuel sender assembly which was a fire hazard. About $700 to repair. I emailed and called Volvo regarding both of these items. They have never responded.
Dt:vehicle stalled/ lost power and died. The electronic throttle body failed and was replaced.
Dt:the contact owns a Volvo S80 vehicle. It intermittently stalled/ died, and lost power. The electronic throttle module failed and was cleaned three times. The line seal and gasket were replaced due to an oil leak. The top engine torque arm was cracked.
Engine shut down on numerous occasions while driving on the highway. No steering response or power brakes to help to stop the car. Very dangerous! the electronic throttle module (etm) on 1999 Volvo S80 was replaced at the cost of 843$.
While driving heard noise coming from vehicle. Suddenly vehicle lurched to right, and hit a parked car. Please provide any further information.
I approached a parking space at approximately 5 mph, with my foot on the brake pedal, however, suddenly it accelerated in spite of my foot pressing very hard on the brake pedal. I tried to maneuver the car with my foot still on the brake to avoid hitting other parked cars and finally hit bushes and a small tree which uplifted the front wheels off the ground and stopped the car. At that point, the ignition was turned off. There were heavy track marks on the hard surface as well as on the grass lawn, suggesting that the rear wheels were locked up. I estimated $6,000 damage to my car and parking area property.
