Months prior to electronic throttle module needing replacement , at my cost, 1999 volvo s80t (@85k miles) engine idle surging and engine warning lights randomly occurred, requiring restarting car when it stalled in heavy traffic. New throttle(gas pedal) was replaced but did not resolve problem. Lastly, while driving on an interstate highway, car would not accelerated beyond 20 MPH(limp home mode) and volvo dealer replaced etm to resolve problem. About a year before, the ABS module was replaced(under extended warranty) because a multitude of warning lights were occurring (ABS, brakes, power steering). While I'm listing failures, the engine cooling fan needed to be replaced(under extended warranty).
1999 Volvo S80 acceleration complaints
Page 3 of 3: complaints 41 to 53 of 53, newest first, as owners wrote them.
While driving on a major highway, during rush hour traffic, the car lost all power. Fortunately, I was in the far right lane and was able to drift safely onto the shoulder. The indicator light read failure. The car would not start, so I had it towed to my home. The car subsequently started, but had developed the same acceleration problems within a few minutes of driving. My son-in-law, a mechanic, believes the problem is with the electronic throttle module and understands this is a common problem with this make of vehicles (volvo). I have not as yet had the module replaced.
The engine died while driving down the street. After coasting to a stop, I was able to restart the engine. Recently when idling, the engine RPM's have surged from about 700 to approximately 1400 without touching the accelerator pedal. Currently when the transmission is in park or neutral the engine surges from about 700 to approximately 1000. When I contacted a local volvo dealer service person, they acknowledged this has been a frequent problem.
Dt:vehicke stalled/died, and lost power due to throttle body failure.
Dt:vehicle stalled/ lost power and died. The electronic throttle body failed and was replaced.
Sudden loss of power and engine stall at highway speed. Pulled car off road safely. Engine restarted. Brought car to volvo dealer who could not identify any problem.
Check engine light has come on 5 times in less than 7 months took to dealer and they said it was a loose gas cap.(which it was not) the last time it was taken to the dealer 9-26-04 and just out of the extended warranty period they say it is now a bad throttle body with a repair est of 950.00. Throttle bodys do not go bad is there information that the dealer dose not have on the repair (cleaning of the throttle body)
Vehicle message center displayes: ABS system failure/servicing transmission system service power steering service emissions control service also, there is an engine oil leak and a tie rod replacement/four wheel alignment was required cruise control is intermittent directional signal inop headlights come on when not commanded etc. Incident date--throughout ownership .
My 1999 volvo s-80 t-6 suffers from a design flaw associated with the throttle body and engine warning light. The light is on all of the time. Servicing does not clear the light, so I have begun to simply ignore the light. The throttle body has a problem where the engine runs properly for 20,000 then begins to oscillate upand down by 200-300 rmps at idle. This seems minor, but it almost caused a major accident yesterday. When slowing to a stop at a major intersection, the engine slowed to idle and then sped up just as I was about to come to a stop. The higher RPM caused the car to move into the intersection. If another car had been approaching, it would have struck my car. I asked my wife (this is her primary car)if she had experienced the same problem and she said she had several times. I went on the web and found that many volvo owners are experiencing the same RPM and engine light problems. I do not know if they have had the same near accident I did, but I must assume they have. Have you received other complaints about this problem and has volvo been notified? I contacted volvo and they denied any problem. The words on the internet tell me they are mistaken. Some one could get killed by this design flaw.
The vehicle experienced sudden acceleration.
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.
While driving between 55-60 MPH driver went to pass vehicle when accelerator pedal became stuck and went to floor, driver turned off igniton and then pedal came back up.dealer could not reproduce defect.
