Cruise Control Problems of Volvo S70

My 1999 S70 with approximately 92,000 has the following issues: - sometimes the engines start shaking? - hard to brake - no power even if you pedal is at the max - cruise control stop working my car has a malfunction with the electronic throttle module and I have been to the deal to get the software upgrade. Since the upgrade my check engine light came on and have had to replace my front 02 sensor. Now the car is undriveable because it will not go more than 20mph with the gas pedal floored. Volvo will not repair this know issue because the car is 10 1/2 years old. They state if the car was less than 10years old or under 200k in mileage they would repair it. This is not fair. They could have replaced this etm when I came for the software upgrade but they did not.

The abs and stc light came on and cruise control became inoperable. It would often reset after turning engine off. After several weeks, the car began to also loose power and it would only run in a higher gear.

1) I was driving alone along state highway 283 in PA, which is a 4 lane (2 each direction) highway in a rural area with a posted speed limit of 65, between lancaster and harrisburg. Most traffic was trucks (tracter trailers). 2) the car (Volvo S70 awd), travelling smoothly on cruise control at about the speed limit, suddenly lost power. Engine was still running, but at a much lower rpm, and running badly. Fortunately I was in the far right lane. I pulled off the road almost immediately to avoid being hit by the truck behind me. I noticed the ets yellow warning light was on. The vehicle seemed able to operate, albeit roughly, at about 30-35mph. Being in a rural area, I drove in this off the highway lane up to the next exit. I took the ramp off the highway, got to the top of the ramp, and the car seemed to be reasonable. Being in a rural area with nowhere seen for reparirs, I accelerated down the ramp to the highway, with the car seeming a bit sluggish, but otherwise ok. Then it lost power again at the bottom of the exit ramp. I pulled over, to the sound of the horn of another truck which was behind me. I shut off the car; waited a few seconds; and restarted the car. It ran much better, but the ets light was still on. After pulling back onto the highway, everything was ok for awhile, but I ran into problems when I hit some slowing traffic. When I tried to accelerate from the slowdown the car did not respond. It was as if I hadn't just pressed the pedal. I nursed it to a Volvo dealership as soon as possible that day. 3) the throttle body was replaced after dealership first performed a diagnostic on the engine. The diagnostic showed 5 line items for the "throttle unit, internal fault. . . " I have a copy of the print out of this report. I have driven the car about 150 highway miles since the repar. The problem has not been observed during this time.

2000 Volvo S70 se. While driving 70-75 mph vehicle bucked and lost cruise control. The vehicle slowed down very quickly and would not regain speed. Each time the vehicle was stopped at a light the consumer had to put it in neutral and keep her foot on the gas pedal to keep it from stalling. The vehicle was taken to the dealer and was informed that the electronic throttle module was defective and needed to be replaced.

On vacation in October of 2004,our 1999 Volvo S70 started to experience sudden loss of speed and then resume at highway speeds, with or without cruise control engaged. We took it to a Volvo dealer and had to have the electronic throttle module replaced. As a result of your investigation number pe05041 I wanted to record my problem with you as well.
