Problems with 1999 Volvo V70 VEHICLE SPEED CONTROL

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.*ak

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. dt

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". *ak
