2000 Volvo C70 Electrical system Problems

“While driving on the highway my check engine light came on. Shortly afterwards I could not accelerate, and had to proceed to the shoulder. I could not see anything visually wrong with the vehicle. I waited a few minutes and it started back up and went on my way. This happened a number of times until I reached my destination. When I took the car into the shop they replaced the electronic throttle sensor. Since then I have been having electrical issues. The car would not start after stopping at a convenient store, I got a jump start. …”

“Irregular engine rpms at idle; car begins to stall before acceleration, and car fails to hold speed. Had car to dealer several times, only to have the 155 software update performed but no etm replacement. Now that magically the 10 year period has just expired, the dealer now claims a new etm is needed at my expense.”

“(1) engine degraded performance...felt like engine was 'missing' and RPM's surged. (2) engine completely stopped in heavy morning rush hour traffic. (3) electronic throttle sensor failed and was replaced by stillman Volvo. Old part unavailable by us. Perhaps Volvo may have it. Incident date is a rough estimate as I do not have the receipt here at work.”

“2000 Volvo C70 lp coupe. Electronic throttle module failure. At approximately 54.000 miles on the odometer, car started stuttering and bogging intermittently. At 56,000 miles, car would actually die and refuse to start. After shutting car down, the car computer would eventually reset and allow the engine to operate normally. Now, every other day, the car's ets light and check engine light will go on and the car will stall.”

“Failure of engine throttle control module (etm) in my 2000 Volvo C70 coupe. Failure resulted in sudden loss of speed and steering assist when driving, as well as, sudden and complete stall without warning. This happened twice, 10/20/05 (ets light did not remain on after switching the ignition off and then on again--see comment below) and 10/22/05. Car was taken into Volvo specialist repair shop for repair (repair cost is approximately $1000). …”
