Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

There are no events leading up to the passlock security system leaving a motorist stranded at any given time. The failure happens at least once a week leaving the driver stranded at whatever location he/she cuts the car off. Sometimes it will be 5min before the alarm will reset and sometimes it will be days leaving the motorist without a vehicle. Nothing done to correct the problem because in this instance the alarm won't reset so the only alternative I was given by a GM dealership is to have the system disconnected.

2005 Chevy Impala often times the vehicle will not start. When this happens the security light on the dash blinks, and, after I wait about 10 minutes, it will start. Upon searching the internet for a solution it is obvious that GM knows there are problems with their "pass-lock" anti theft system but will not acknowledge it or repair it for anyone. My mechanic replaced the battery and found no other problems. Suggests I take it to GM dealer.
