In owners' own words
2003 Impala not starting. Leaving me stranded for hours till it decides to start. After searching on line for endless hours. To see its happened to several people. To take it to the dealership pay 180.00 To be told its was in the theft deterrent setting. To get home and a hour later it wont start.. Chevy needs to find out the problem and recall this issue too many complaints that I can read on line daily. Electrical system
