1 Underhood Wiring problem of the 1999 Volvo S80

Failure Date: 01/10/2006

Transmission problems causing dangerous driving conditions. The transmission slips when going between 2nd and 3rd. Also had issues with the engine going to 700 rpms when going 65 mph. This is just one of the many problems. The solenoid went out in the transmission about 13000 miles ago. Currently I have three different error codes "transmission service urgent", low oil pressure stop engine ASAP", and "emission service required". I have read many other people have the same problems I have had. Nm.

2 Underhood Wiring problem of the 2000 Volvo S80

Failure Date: 10/19/2005

2000 Volvo S80 t6 on numerous occasions the vehicle would stall, even when driving at highway speeds. On several occasions while driving my children to school on the highway the vehicle stalled forcing me to cross 3-4 lanes of heavy traffic without the use of power steering or power brakes. The electronic throttle module was determined to be defective. This is a known defective part on 1999-2001 Volvo S80's. There are even documented reports that the etm will fail on over 90% of all Volvo S80's within this year range ('99-01). I have spent $900 to have this replaced. The state of California is filing a lawsuit against Volvo over this part. I live in ky; therefore I don't believe that lawsuit will help me. I am asking Volvo for full reimbursement to replace this part. It not only was a faulty design, but also potentially deadly part. There should have been a full recall on this part and Volvo knew about this problem even before the release of the vehicle in '99. There is another know defective part on the same year Volvo that is the abs module. I had to have that replaced for a cost of $1000. Documented reports say the abs module will fail on 60% of those Volvos.

3 Underhood Wiring problem of the 2000 Volvo S80

Failure Date: 12/25/2004

Subject: engine compartment fire, result: total loss, ehicle: 2000, Volvo, S80 2. 9, VIN: yv1ts94d4y1123678. Shortly before 3:00pm my wife and I departed bridgeport, connecticut for the trip home to massachusetts. The first 7 or 8 minutes were local stop and go driving (maximum speed 25mph). At this point we entered the merritt parkway (eastbound entrance 48). We joined the right lane traffic flow, which varied between 55 and 60 mph. Approximately 2 minutes later ? just before the merritt parkway eastbound entrance 49 or 50 the car engine lost power. I was able to coast the vehicle off the highway to the island between the highway and the on-ramp. It looked like steam was coming out from under the hood near the radiator. I look at the dashboard temperature gauge and was surprised to see it reading normal. I pulled the hood release lever inside the vehicle, got out of the vehicle, went to the front of the vehicle and attempted to release the hood safety latch which was so hot that my hand withdrew involuntarily. At this point I became aware that smoke was coming out from the front of the hood, not steam. I alerted my wife to get out of the car. She did, and after moving away from the vehicle, looked back and noticed flames coming out from under the front of the engine compartment. My wife and I witnessed two explosions, eminating from the engine compartment. The first explosion caught my attention because it was loud and shot flame and smoke about 15 feet into the air.

4 Underhood Wiring problem of the 1999 Volvo S80

Failure Date: 06/01/2001

Underhood wiring harness is protected from heat/elements by a convoluted tubing. The convoluted tubing has become very brittle, turned to powder and fallen off the harness leaving the harness unprotected. Volvo is apparently using a tubing plastic underhood that cannot withstand heat! the wiring harness on my car is now left unprotected and will likely suffer premature failure similar to every other major system on this car.
