Security passlock system keeps car from starting at random times. Safety concern is that someone can get stranded on a sub-zero cold night or can be in a dangerous situation and not be able to start the Impala. Car will work fine for months at a time, then randomly will not start. After 15 minutes or so, the car will then start... sometimes. There are many complaints of this problem (see and look under electrical problems).

I have had issues with my 2001 Chevrolet Impala regarding the passlock sensor, which is part of the ignition switch. There's a service bulletin out on the part. I've contacted GM and they out right told me that they weren't going to do anything about my problem because my car has too many miles on it. I had the part replaced within the first 6 months of purchasing the car brand new. I had it replaced again on 11-10-05, which took a year and a half to diagnose the problem. Now I am having the problem again. I contacted Chevrolet today and they refused to even help...wouldn't even open a complaint for me. They're saying that no one else is having this problem, but I've researched forums and it appears that several people are having this problem. I don't feel that I should have to pay to have this repair done again since it was done 11 months ago. I'm irritated and I would like a response from someone as to what will be done.

: the contact stated the security light illuminated intermittently without cause. After the illumination occurred, the vehicle failed to start until the engine rested for 15 minutes or longer. The vehicle was driven to the dealership where the problem could not be duplicated.

For the last year, every so often, my Impala won't start. I've put a new battery in it, but the day I did that, it still wouldn't start. I took it to the dealership to have them look at it, but they weren't able to duplicate the problem and also refused to work on my car. In contacting Chevrolet regarding the problem, their response was for me to trade in my car and make it someone else's problem. The dealership told me that it could be one of two things, either the passlock system or the ignition switch and both would cost around $700 each to fix. I'm tired of wondering if my car is going to start or if I'm going to be stranded somewhere.

Car security light has come on and then would occasionally be unable to start the car. Turns out the passlock anti theft system is not working correctly and would cost $450 to repair. There should be a way to disable or bypass the system since I could really care less to have an anti theft device for my ignition. Now I either have to dish out the money to the dealership (other mechanics seem unable to repair this of course), or take the risk that the car will not fail to start somewhere with my two little kids in the car.

I have a 2001 Chevrolet Impala ls and I noticed a problem with it right after I bought it. The security passlock system is either not functioning well or it's defected, I researched the problem on the internet forums and I found out that almost 70% of people that own Impala have the same problem. I took it to the dealer and they gave me an enormous sum for the replacement. Why should the buyer pay for something that is obviously defected when the majority of the owners have the same problem. GM is at fault here and the owners have to pay for it. I, and many others, believe that it is not us at fault, but GM since they are aware of the high failure rate of their passlock system. My question for you is: Why didn't GM issue a recall for this defective part" what can the owners do so we can initiate a recall for this problem"
