My 2000 Volvo S80 T6 stalls (typically in junctions) after 120K maintenance service / recall 155 ETM software upgrade. The service was performed on 5/12/06 at authorized Volvo dealer (128volvo.com). Since the service, the car stalled 5 times, and has been to the dealership three more times, without a fixing the problem. The dealer rejects my complains and wants this issue to "happen more frequently before taking action". sudden stalls almost lead me to a traffic accident already at least once; the dealership isn't concerned about traffic safety.

(1) no warning prior to failure (2) the engine suddenly stalled, leading to instant loss of power / speed. The very first time it happened to me was 2.5 yrs ago(July, 2003) the day after I bought the car at 62 K miles. The engine stalled when I was driving @40-50 miles/hr for 6 miles. The car was towed to the garage and a throttle was replaced. Then, after 2.5 year, when the mileage reached 91K (less than 30K after throttle replacement), the same stalling appeared again. The first time it happened was around 12/10, when I parked the car. The second time was on 12/18, when I pulled over to a traffic light the third time was on 12/19, again when I approached parking lot, to take it to the Volvo service. (3) in the first day at Volvo dealer service (@ 96th St., indianapolis) could not diagnose the problem: No error code was found. In the second day, upon my request, the service personnel drove the car for two or three miles and the car stalled again. I was told that they found the error code, and determined it related to air intake / throttle. I was also told that the repair would be under Volvo extended warranty of throttle cleaning, which I was not notified but found through NHTSA website, and made inquiry to the service personnel. Today is the third day of car in the garage, and I have not heard any word from Volvo dealer. I am afraid any fix I receive today or in the near future is just temporary, as the same problem happened at 62K. Even after new throttle was installed, this problem appeared at 91K. I was also told by the Volvo dealer that the previous owner had the same problem.

Service engine light - urgent went on. I noticed slight hesitation in car only when this light is on. Service light comes on & off. Went to dealer and informed that I need a new throttle body unit at a cost of $1129.95. Car only has 73,000 miles and is regularly serviced by Volvo. Informed that this is not under warranty. Went on line to NHTSA and discovered many complaints regarding similar problem.
