Ignition Switch Problems of Buick Rainier

The contact owns a 2006 Buick Rainier. The contact stated that upon starting the vehicle, the engine stalled and the passenger side air bag warning light illuminated intermittently. The vehicle restarted after multiple attempts. However, the failure recurred multiple times. Also, the contact had stated that there was a burning odor present. The vehicle was taken to the dealer for a diagnosis. The technician stated that the ignition switch, various wires, and throttle body needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. However, the VIN was included in NHTSA campaign number: 12v406000 (electrical system, visibility). The approximate failure mileage was 112,000.

The engine quits unannounced and the safety lock dash light illuminates. This can occur anytime regardless of speed. If at highway speed, the car will restart on itself. At low speed, I have to put the tranny in neutral and restart the engine. The dealer cannot find the source of the problem but suspects the ignition switch. The problem is what is causing this issue?.

The current investigation into faulty ignition switches is much broader than currently being investigated. . In 2004 I purchase the Buick ranier above. On initial test drive with salesman the vehicle shut off at 35 mph. After review by the mechanic it was attributed to a computer issue. I purchased the vehicle after retesting. During the next 4 years this happened at least 3 more times. Each time it was attributed to a computer upgrade. I have not had a problem since then in 2008. The symptoms and the results are consistent with all reported failures. I also have a friend with a Buick full size car 2006 I believe who had the same issue. The reports that this has not occurred on Buicks or SUV is not correct. This is a larger problem.
