Three problems related to check engine light on have been reported for the 1999 Volvo S80. The most recently reported issues are listed below.
For the past year my check engine and urgent light have been popping on. I have to go to my machanic (who is Volvo certified) to have them turn off. But the check engine light comes on more frequent now. For the past 6 months, when I start the car, it hesitates and runs rough, like it is going to stall. The first time this happened my machanic said it needed a tune up. Today 10/19/06 I brought it to my macanic again, and they told me it was the throttle module and the 1999 S80 's are having all the same problems, and that I need to take it to an authorized dealer, before it gets worse.
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.
I have had several problems with this car. Frame, engine, transmission and drive shaft, steering, and power locks. I have had the transmission replaced twice. I took it in for service 6 times before they repaired the problem. I have taken the car in with 8 bulb position light complaints, 3 steering complaints, 4 complaints regarding the check engine light coming on, and the most recent problem, the engine just quits while driving. I have been without this car for over 7 weeks this year alone. I am stuck between the dealer and the manufacturer. Volvo has responded to my complaint that I filed with the new motor vehicle board by say, "a Volvo technical specialist and lawrence Volvo's service tech have driven the estes' 1999 Volvo S80 in excess of 500 miles and determined that no non-conformities exist. In an effort to demonstrate that we value the estes' as our customers, lawrence Volvo will contact them to make a very fair offer to trade them into a new vehicle. " I don't want another Volvo. I want mine fixed or Volvo can adjust the purchase price or buy it back. I recently received a recall notice on the car and now fear even more problems.
