Engine stopped running, dash gauges blank. I managed to pull over without power brakes or steering! after a few minutes I was able to restart with "reduced engine power, traction control off, and stabilitrac" problems displayed on dash. I was a mile from home in -10f temps! I pulled it into my shop. Dtc code p2135 which has to do with throttle position sensor. The dealer has a 2 week delay in getting into their garage! I found out that the throttle body/sensor is not covered under warranty. So with the cost of a tow (can't trust the truck to make to dealer) plus the part cost, I will repair it myself. The reason for this letter, I discovered that this has happened to other GMC truck owners. Their vehicle quit in the same manner. I think that "reduced power" is not the same as no power!!! I wonder what would have happened to me if I was on the freeway during rush hours??? be prepared for some creative driving!.
