2 Anti-theft Controller problem

Failure Date: 02/16/2012

We have a 2001 Chevrolet Impala LS, and have had a couple incidents involving the vehicle anti theft system. The vehicle wouldn't start, and would display a security warning on the dash. Typically we had to wait about 10 - 15 minutes to try again, and the vehicle would start. I have looked online and have found many complaints about the anti theft failing on these vehicles not allowing them to start. Gm has not issued a voluntary recall, and even after the alleged issue has been fixed by a dealership, many owners have complained the issue still exists.

4 Anti-theft Controller problem

Failure Date: 10/06/2011

My car will not start due to an issue with the passkey/passlock system. It is a anti theft function installed on several of the gm models that when it fails to work it actually keeps the owner from using the vehicle. After going on line to research this issue I noticed that this was a very common and expensive problem to have. In addition to getting the system fixed many owners say that after about 3 or 4 months the problem comes back and have even died on them as they were driving. Some try to bypass this system and others attempt to have it fixed, but regardless of how they deal with it, I believe that it is the manufactures responsibility to address common propblems with the vehicles they sale; not to mention that Honda was having the same issue with their vehicles and issued a recall.

5 Anti-theft Controller problem

Failure Date: 06/22/2011

As I've found from many other folks through the internet and in person, the passlock system in my 2001 Impala is faulty and dangerous! the best case scenario the engine won't start and when you come back 15 minutes later it starts just fine assuming you are in the comforts of your own living space. When on the road this is a severe problem!! also, my wife recently was driving through and intersection and the vehicle just quit! same issue. Wait and it starts!!! now in this case there wasn't and accident, but very easily could have been!! cars dying when making a left turn is not my idea of a safe vehicle!!! since that episode, we've had the vehicle looked at, but no one seems to be able to find the probelem. After some research, I'm now 100% sure it's the passlock anti-theft system. Once again, this very morning we went to drop kids at daycare and the car would not start. . . . . . . . . . . . Wait 15 minutes and it starts just fine. There is and obvious problem with the anti-theft system on these vehicles and they need to be addressed!!!.

8 Anti-theft Controller problem

Failure Date: 10/20/2006

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.

9 Anti-theft Controller problem

Failure Date: 05/26/2006

: 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.

10 Anti-theft Controller problem

Failure Date: 04/16/2006

I have a 2001 Impala we bought new. It has 62,379 miles. I took it in for a brake job last month for the first time. The company I use has a good reputation in town. They told me after the first turning of the rotor which they did that there was not enough metal left to turn again. That seems ridiculous. Also, the car at times wont start and have to let it sit for 10-15 minutes before it will start. I have read a lot of reviews on various sites and it seems this is a very common complaint. I can't afford to throw out hundreds of dollars jut hoping that it will be fixed. I have heard anything from the ignition switch going bad to the passlock anti theft systems errors and or the bcm module going back. Also someone suggested that I might just need to get a new key cut as the old was has gotten worn and the anti theft devise is thinking that someone is trying to steal the vehicle.

11 Anti-theft Controller problem

Failure Date: 09/30/2005

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.

12 Anti-theft Controller problem

Failure Date: 06/27/2005

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.

13 Anti-theft Controller problem

Failure Date: 05/19/2004

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 Impalas 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 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?.
