We've had this problem since it was new! Never had it activated even! The book is worthless on deactivating it! I was told by one mechanic to replace the ignition, what is that going to solve!!!!!! Bradshaw Chev. in Cedar City, Utah doesn't even have a solution!!! They ripped me off to begin with, so no doubt!!! It's a hastle to sit and wait for the light to go out to start my car! I tend to run all my errands and leave it running, even at the grocery store! I hate this car. Patty
