A common (and totally random) problem with GM vehicles that have the Passlock / Passlock II anti-theft system is that the vehicle will suddenly refuse to start. The problem is a poorly designed GM Passlock anti-theft system that erroneously enters anti-theft mode and disables the fuel injectors. GM should be forced to recall this Passlock system — it is simply unacceptable to strand motorists because of an incompetent anti-theft system.
The vehicle in this example is a 2002 Chevy Malibu, but this Passlock system was employed in many GM models. Thousands of motorists have been stranded and left helpless by these GM vehicles that refuse to start for no apparent reason. The owner of this Malibu was stranded three times over the past two years, incurred 2 towing bills to a Chevy dealership, two “repair” bills from the incompetent Chevy dealer who obviously failed to solve the problem. Now she was stranded for a 3rd time. This time she called me.
