Cruise control randomly quits working.. i was passing a semi and the cruise just shut off.. and starting blinking.. has been doing this right along, since i bought it at 46,456 miles on it.. i now have 93,000 on it.. i have to pull over and do the "gm" oil reset code.. turn the key to on position, and pump the gas pedal 3 times to reset it.. it is dangerous... specially when it turns off while passing or driving.at 70 mph
