I have noticed a few instances at night that my headlights and dash lights will flicker simultaneously just a bit, especially just after a cold start. I drove about 40 miles round trip the other night and this happened 3-4 times each way. I've read on several boards that this is known GM problem and that there is a TSB on this. I've also heard that this is related to the voltage regulator in the alternator and the stability control feature kicking in. The problem tends to go away after driving ahile, but have never noticed this before. Anyone else noticed a slight flicker recenlty and whether or not there is a cure?
