Cruise Control problems of the 1999 Volvo V70

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.

Failure of the electronic throttle module resiulted in erratic throttle response. Surging on idle was causing problems if brake was not applied strongly enough. Cruise control was also erratic in function. Took to the dealer for replacement @ $1200. 00. They gave no indication that this was a chronic problem. I only discovered the chronic nature of the problem on a bulletin board web site for Volvo's.

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".
