One problem related to starter has been reported for the 2004 Chevrolet 1500. The most recently reported issues are listed below.
The vehicle will not start and the security light flashes showing that there is a passlock system problem. The system sensor thinks that it has been tampered with and shuts down the starter. After some period of time usually about 30 minutes it will reset and the vehicle will start again. As time goes by the problem becomes more frequent and the time of reset takes longer, until at some point it will not start at all. Chevy refuses to acknowledge that there is a problem with their passlock system, but a little research on the computer shows that it has become a common problem. Being stranded may not seem like a big deal, but in severe weather conditions, or medical emergency it can be life or death. Since chevy refuses to acknowledge a problem they don't send out information to their shops about how to fix the problem so consumers are spending huge amounts of money on unnecessary parts and labor. This is the third electrical problem my vehicle has had, I am concerned about the entire electrical system going up in flames.
