Active fuel management problem - oil passing the o-rings on the pistons which is causing the check engine light to come on and one cylinder out of the seven not working at all. It caused 2 new spark plugs to break.
Traveling at 65mph in -25 degrees f, our check engine light and stabilink traction control lights came on. Dash display said vehicle would lose power and our engine shut-down. We pulled over on a snowy highway and read blogs and found our throttle body sensor would crack and fail at extreme cold temp. We started vehicle and it reset, but same problem happened within 5 miles. I found a auto-zone in princeton, minnesota and bought part and replaced myself. As it was new years eve no gm assistance was available. Gm tells us there was a service bulletin but they failed to notify us. Also told us a dealer would fix the problem for free, but failed to tell us how to get to a dealer with the engine shut down. I researched and found this problem common at cold temperatures. Gm was dangerously irresponsible by not notifying us. They put us in a bad situation in extremely cold temps. I fail to see why this wasn't a recall when your vehicle basically shuts down. We could have easily been rear-ended or spun in a ditch. Thanks to blogs with no help from gm, I fixed the problem myself at extreme cold temp. Gm will not cover my $190. 00 for part, not counting stress,time and labor. How can they say they verified we received no notice, but would not cover our costs. I am sure there are many more drivers put in this situation. Thanks gm.
