One day I was just going to work like and my car wouldn't start. The security light was flashing so I referred to the manual. I found out it was the passlock feature on the car and it was malfunctioning. I don't have the time or the money to fix the problem.

Car randomly doesn't start. When I first got the car(6 mos ago) I replaced the starter having no idea that this has been happening over and over again to many Impala owners if not all of them. Started fine for 2 weeks and it's been happening ever since. Sometimes when the car doesn't start it trips the passlock and I have to wait anywhere from 10 to 30mins before it resets in order to try starting again. I've been driving the car and at quick stops I have to leave it running to be sure I won't get stuck there for 30 mins or so. I've also been stuck at gas stations waiting 10 to 30 mins(at the pump) for it to start again (very embarrassing). After all the complaints I've read I'm afraid to spend anymore money on this problem.

Received 2000 Chevy Impala as an inheritance. Within 2 weeks car at times would not start. All lights on dash would illuminate followed by the yellow/orange security light. This is due to a passlock problem where the passlock system thinks that something other than a legitimate key is being used to try and start the car. My sister had this problem and at times would have to turn the key in the ignition to "on position" and wait 10 minutes. After several days of research I was able to determine that to reset the passlock system the key needed to be left in the ignition switch in the "on position" then removed and repeated two more times (3 times, 30 minutes total). After doing this I had no more problems. My only problem is there are lots of people out there that are not mechanically inclined, and plenty of people have had to had their vehicles towed and face a diagnosis fee (and plenty of times misdiagnosis). According to all the information readily available Chevy/GM has to know about this and I consider it shameful that they do not allow some kind of concession or modification so that a customer of theirs with a legitimate key cannot start the vehicle.

My wife is scared to death when she is in the parking lot just sitting there waiting for the car to reset. Intake gasket failure 2 times in 100,000 miles $600 each time. Sub frame failure intermediate shaft failure 3 times.

My 2000 Impala has a problem with the passlock system which causes the vehicle to stop working or surge while driving and causes intermittent difficulties with starting. This is a widespread problem among GM owners and we have made nearly 13 visits to the dealer to address this safety issue. We have had the ignition replaced, but on most visits GM staff are unable to diagnose, and hence, unable to treat the problem. Another safety issue is related to starting. Since my wife drives the car, she is often left unsafe in areas during the 20+ times that she has not been able to start her car. While no injuries have yet been linked to this problem with our vehicle, is such a widespread problem with GM vehicles that it needs to be addressed. Thank you for your attention to this matter.
