While passing a vehicle I lost all electrical power which in turn caused the vehicle to lose power. This same thing has happened several times at low speeds. I have the vehicle scheduled for July 2 to get looked at. The engined revved extremly high and it seemed like the transmission went into neutral. It then restarted. I had to roll the driver's window down and got a stabili Trak light that came on after the incident.

Fuel vaccuum sensor keeps telling me to tighten gas cap. Engine light comes on perioadiclly. According to my mechanic, dirt gets in near where you fill gas. Sensor and filter need to be replaced by updated GM. The vaccuum sensor and filter need to be replace and reroute line above transmission instead of truck body. Dealer part cost $477. Should this be a recall situation?

I temporarily had no control over the vehicle causing me to have an accident. While driving down a residential street approaching a stop sign intersection I merged into the center of St to pass a trashcan and in the process of returning to my correct position on the road I suddenly had no steering. Panicking from the loss I pressed my brakes an attempt to bring vehicle to a stop but was unsuccessful because the tires began a slide once noticing the traction loss I proceeded to release brakes and reapply in hopes of gaining traction the brief relief from brakes caused the vehicle to regain traction and while I still have no control over steering, the vehicle jerks towards the right side of the road and the brakes being reapplied the vehicle continues to slide off pavement making contact with stop sign and telephone pole.
