1999 Volvo V70R AWD, 56958 miles 1. no noticeable events leading up to near crash except for when using cruise control vehicle had a tendency to not hold steady speed. It seemed to want to hunt above and below set speed in order to maintain set speed. 2. stopped at a stop sign waiting to cross a busy highway, started to proceed when clear and vehicle hesitated for 2 or 4 seconds and then regained normal acceleration. Nearly hit broadside because of hesitation of engine. Within 20 miles ETM light went on and car went into limp-in mode. Vehicle required several minutes to accelerate to 30 mph and would not exceed that speed. I was 130 miles from home and was required to haul it back on a flat bed because it is an AWD. 3. replaced throttle body #8644347, software #9438298-3 2518 and gasket #8636753 to correct problem. Cost was approximately $1200 not including towing. Yes the old part is available for your inspection.

1999 Volvo V70 station wagon glt. The vehicle suddenly lost power and speed. Consumer was just driving and it started losing power. When putting pressure on the gas pedal it started bucking. When consumer first contacted the dealer he told him that if consumer left vehicle sitting for a while it would start back. Dealership claimed it was the electronic throttle control module. This part was replaced on 4-1-05, and later failed on 7-29-05. The dealership replaced it again at no charge. There have been some other electrical problems. Consumer had not picked up the vehicle from the dealership as of yet. Before these incidents occurred the cruise control quit working, the electronic throttle system light and engine warning light came on.

My 1999 Volvo V70 stalled in traffic causing me to lose power steering. Luckily traffic was moving slowly because of an accident and I was able to pull the car over and restart it after several tries. I took it in for service and they cleaned fuel deposits off the throttle, but informed me this was a common problem with this model and if the problem persists, I would have to take it to a dealer for a $1,600 dollar repair of throttle control.

Ets and check engine light appeared and car refuses to accelerate and idles rough. This can occur at start up and then while driving the car. It was diagnosed as a bad throttle body and/or electronic control module. This is a common occurrence in this generation of Volvo.

The ets (relating to throttle control module) keeps coming on during acceleration followed by very sluggish performance of vehicle. Previous times upon light up, I've taken this to the dealer and both times they state nothing was wrong and reset the system. This should have been replaced during the warranty period. I'm afraid that there could be a major accident soon due to this problem.

ABS brake, check engine light, transmission lights all came on. Third time in 11 months. First service was a soft ware patch. Hardware replaced last week and same problem happened again. Manufacturer unwilling to assist with problem.

I was on highiway 5 in san diego. I set the cruise control at 65mph. When I approached a congested area, I manually pushed the cruise control switch to the "off" position. With the cruise control in the "off" position I continued driving through the congested area. As I was leaving the congested area, I decided this would be an ideal time to push the cruise control switch into the "on" position, in preparation for driving at the higher allowed 65mph speed limit. While travelling at 30mph I pushed the cruise control switch into the "on" position. As the car was new to me, I did not recognize that there is no clear detent signifying the "on" position. Unknowningly I 'overpushed' the switch from the "off" position, pass the "on" position, into the "resume" position (thinking that this ought to be the "on" position). I removed my finger from the switch and immediately the car began accelerating (I later came to realize it was accelerating to 65mph, the setting prior to the switch being turned off). My complaint is that when I pushed the switch into the "off" positon, all prior cruise control settings should have been eradicated (as it does in my GM truck and previous cars I drove). A driver, as I did, not knowing that the cruise control memory does not clear when the switch is pushed into the "off" position, could experience an uncontrolled acceleration and a resulting collision when the switch is pushed beyond the "on" position. An individual, as I, having driven a GM vehicle with factory installed cruise control control is used to having the "off" position separating the "resume" and "on" positions so that the operator must select a distinct, exclusive motion for "off" "on" and "resume".
