I have a Chevy 2004 Impala LS- This car has multiple problems over all (control panel not working-" traction off" comes on and car doesn't want to start). However, right now I keep getting stranded when I take the car out. The Security light keeps flashing and the car won't start. I have to set the ignition to on and monitor the security light flashing at me for about 15 mins until the security light stops flashing then the car will start. Today I had to go through the process 3 times before car would start. It was 97 degrees out today. I am stranded in parking lots and always have to be aware of what is going around me. With the recession there are always panhandlers coming up to me begging for money and this frightens me. I have fought with Chevy about this problem and they refuse to address it unless I take it to a Chevy dealer only and pay for diagnostics and repairs. With all of the complaints about this problem I believe it is Chevy's responsibility to fix it. I have already informed my family that if anything happens to me they are to go for Chevy as my safety was ignored by them.

Impala ES V6

  • Automatic transmission
  • 79,889 miles

I have a 2004 Chevy Impala I have been having problems with my security light, it won't let me start the car for a good 15 minutes. I have had the ignition fixed ($289.00) and a new cluster panel, checked electrical and the problem is still happening. There will be days it works and then it is days when it doesn't work. I need help.

GM needs to recall this problem because I see there is a lot of complaints about this problem.

PLEASE try this before you do anything else. DON'T pay GM or your dealer for a new ignition, BCM, or anything else that probably won't work anyway. I tried everything as I've had this problem(I'll skip all the details since we've all dealt with the same aggravation) off and on for quite a while. I followed the advice of someone else on this site and it absolutely worked for me. Locate the BCM (computer) under the dash on the driver's side by removing the panel by lifting the two tabs. Unplug the grey connector that is the electrical connection between the ignition and the BCM. It is the farthest one in and is one of three connectors in the black box (BCM). Spray both ends of the unplugged connector with electronic connector cleaner. I got mine at Advanced Auto Parts for $7.95. I plugged the connector back together, turned the key, and voila! She cranked right up. It's been two weeks so far and no problems. I'm also going to try a premium spray you can get online for about $20. It's called deoxIT and someone else on tis site has used it and has not had a reoccurrence of the problem for 2 and a half years. these products remove the oxidation from the crappy materials that GM used to make the connector pins. Good Luck!

Follow instructions to fix the problem such as replace the battery, replace starter, replace starting relays, replace the body control unit, and the same problem continues as of today 11-23-2013. Wait about 20 minutes and it will start every now and them. I never know when it will happen again.

The Security light comes on and then it is a game of Russian Roulette from that point. At some point the car will not start. I can get it started after leaving the key in the ingnition in the ON position for about 10 minutes or so, it has been a liltter longer lately. I have taken the car in to have it looked at, but the mechanics can only read the problem when the Security light is on. I got lucky once, and the Security light come on when I was able to get to the Chevy dealership from which I purchased the vehicle, and they were able to get a reading on the problem, or so I thought. I had the BCM replaced for $479, only to have the problem reoccur one week later. I took it back but the sympton did not repeat itself, this was in April of 2011. Frustrated, I just learned to live with the problem. I have asked several mechanics what the possible causes are, and all have said I have to take it to the dealer when it comes to the Security light. Well, I did and it cost me $479, with a "well it could be the PCM, but we are not sure" Oh by the way, the not sure factor could cost me $500-$700.

I will be in the market for another car in the next few months, and I will tell you, I will not be looking at a Chevy product.

Over several years had problems at random times starting car. Security light would come on. Mechanic could not find problem. Dealership worked on it once but problem reoccured. Finally brought it to dealership and left it for about a week. They randomly tried to start it till it happened to them. They determined that ignition which is connected to security system was to blame. They replaced ignition and we haven't had a problem since.

Impala 3.2L

  • Automatic transmission
  • 105,000 miles

I have had the same problem with the security light going on and it not starting. My mechanic recommended that I put the key in the on position for 10 mins, turn it off and then start it, it works every time. Problem is, it makes me late and I wonder when it won't work any more - this is a definite recall item for Chevy and since they refuse to do anything about it, I will NEVER buy another Chevy!!!

Impala 3800

  • Automatic transmission

the problem with security light coming on,then after the engine will not start. is this suppose to be a common problem? what is general motors saying about this problem with these cars? is there a recall concerning this problem? kinda reminds me of the chrysler era when they were putting out lemon cars and just ignored there customers totally. i never bought another chrysler/dodge product again,and thinking of doing the same with gm. but, in the mean time how is this problem solved? call me sick of this problem!

Security Light comes on, then if I have to stop and park I come back out & car won't start, very annoying you never know when you are going to have this problem. I brought car in 2005. It has been a pretty good car but now it's really beginning to act up. Just found out now I need an engine.

The security light kept on while I was going on a cruse. I stopped off at the store, and I thought to shut all the ACC. off. Fortunantly, the car stared up!
