Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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. …”
