Two problems related to engine shut off without warning have been reported for the 2007 Chevrolet Trailblazer. The most recently reported issues are listed below.
My son in law was driving the car with my permission and while making a left turn the vehicle stalled; there was no steering or brakes. The steering wheel locked up during the turn and caused the vehicle to continue turning on it's own and I proceeded to hit a pole. The radio and lights were still on during this time, however, the engine shut off.
While taking my kids to school this morning, the engine shutoff shut off with no indication at all. We were starting to slow down to turn the corner to head to the school when this incident occurred. We have had several components (battery, ignition switch, alternator, starter relay) changed out the fixed the engine light, but the engine continues to stall. I have seen over 500 other people with this same issue and have not seen anyone who has had it fixed yet.
