After stopping at a stop sign the vehicle stopped dead in the intersection. Would not restart, could not be steered as there was no power at all. Vehicle was towed to dealership where a "new" ignition switch was installed. But no new shorter key with a hole in it was given to me. How can I be sure the new switch will not malfunction. This is exactly what has happened to the recalled vehicles. If I had gone two blocks further it would have been in a busy major highway intersection. So far no response from complaints to various GM sources.

Trailblazer 8-cyl

  • 27,225 miles
On the 2008 Trailblazer, had two problems with the ignition switch. In April 2011 the tumbler mechanism portion of the ignition switch failed at approximately 27,225 miles and was replace under warranty. In May 2014 had difficulty starting the vehicle when the ignition switch was in the start position. Was able to start the vehicle and drive to the Chevrolet dealership. While waiting for the service technician, I moved the tilt steering wheel to a different position and the vehicle stopped running. This would have been an extremely dangerous situation under normal driving conditions. It was diagnosed that the electrical portion of the ignition switch had failed. The ignition switch was replaced. The approximate mileage was 71878.

Since owning the vehicle; purchased used in 2005 from a dealer; we have had to replace the ignition switch twice. Called to report problem to Chevrolet since all the news of ignition switches; they didn't seem concerned or interested since this vehicle was not listed on the recall list. It has left me stranded twice and has cost me approx. $400.
