2000 Chevrolet Blazer Owner Comments

problem #2

Dec 152006

Blazer 4WD 6-cyl

  • Automatic transmission
  • 53,000 miles


See NHTSA item# 623034. Security lamp illuminates while driving and then the associated "passlock" security system either stalls out my engine while driving or causes a shut-down of my vehicle whereby the engine will not start for at least 10 minutes. This has happened late at night, at intersections, gas stations, etc. The amount of times I have had to wait for this security system to "reset" has become frustrating. I have done extensive research on this via respectable online forums, and there are many owners not just of the 2000 Chevrolet Blazer but of a number of vehicles in the entire GM family who have this same problem. We are all crying out for a recognition of this being a safety issue, not just an issue of inconvenience. Failure to start and stalling are symptoms that are only going to lead in one direction. There are literally hundreds of posts on this issue if one goes to an online forum and searches under the terms "security light" or "passlock" within the GM context. I have been to my dealer numerous times, have attempted to work with Chevrolet, and nothing seems to be getting resolved. I am under the impression that a mechanical solution to this problem does not exist, short of disabling the system altogether (which dealers are not allowed to do). I would welcome any further contact from NHTSA regarding this matter and would gladly go to the expense of photocopying and sending the binder of materials I have collected on this subject. If it will make a difference in preventing a future injury or death (if any have not already occurred), I am all for it. Thank you for your time and efforts on behalf of auto safety.

Told by dealer's service dept. We have to pay approx. $ $800 to have the frequency part of security panic system replaced. Vehicle is still under full warranty. The horn is constantly going off at various places. I have to disconnect the horn fuse in order to keep battery from being run down. What can be done about this?
