2004 Chevy Impala. Security light goes on and then car won't start. I have to wait about 20 mins. To start. I have taken it to two different dealers over the past 3 years and spent plenty of money but still having problems. Research online has revealed this is a long known problem. When will car manufacturers be forced to 'fess up and fix this? no wonder the big three are going under.

While my complaint may not be 'safety' related, it is certainly an issue. I have 2004 Chevy Impala that is suffering from a common and known passlock problem. How can Chevy be allowed to produce faulty products" if this is going on how do I know that the safety features on my car will work" I am so disturbed by this.

Automobile quit running while on highway and failed to restart. This situation, I feel, put mine and my wife's lives in danger. Research has revealed this situation is common in this type of vehicle. Passive security system overrides operators attempts to start car. Calls to GM and GM representatives produced negative reaction to consumer complaints.

My speedometer and my temp gauge in my 2004 Impala (with 55,000 miles)do not work. I attempted to leave work last night and my car had a problem starting-my security light stayed on until I got home and my clock reset. I went to move my vehicle today and it will not start-it will click, but will not start. I have replaced the battery and yet it still is having problems starting.

2004 Chevy Impala would not start. Security light came on. Called the dealership and was told that the vehicles security anti-theft system can sometimes lockup making it appear as if the car is being stolen. Very expensive to replace. Was told to reset the security system as follows...turn key to on position and wait 10 minutes until security light stops flashing. Turn the key off for 5 seconds and restart the car. This has worked each time we have had this problem, however, my 17 year old daughter was stranded..by herself..at 10:30pm in a university parking lot and had no idea what to do. Luckily she had a cell phone so she could call me. I stepped her through the process to get the car started again. This could be a serious problem for young women to be stranded. I searched the internet and found several people having the same problem..even in much older models. When is GM going to fix this problem?

Security light went on last month. It was taken in immediately for repair. I was told it was the ignitiion cylinder. The car also makes a vibrating noise on accelerator. I was told this was the drive shaft and the catalitic converter. All replaced. The car still made noise when left service at northeast auto center in philadelphia pa where it was purchased. Yesterday the light for security is back on. 2004 Chevy Impala very disappointed. Car has 55,000 miles. At 36K the radiator and water pump went during funeral procession.

I have been having trouble with the car starting. We thought it was the battery. We bought a new one. It did not help. When a mechanic look at it he said that it may be a neutral safety switch. He told me how to start it, first I have to have the key on the on position and the car in neutral to start it. This helped, but I was wondering if anyone else has had any problem like this?

I have a 2004 Chevy Impala. It now has 43,000 miles on it. We purchased it Dec. 30, 2004. It only had 13 miles on it. Over the past month it failed to start twice. I took it to the dealer and learned that the passlock sensor needs to be replaced at a cost of $475. After investigating the issue, I've learned that this has been a common failure in GM cars for many years. One would think that this type of failure should not be so common, and especially on such a young car. GM should be pressured into redoing this system. At $475 per car, they are making quite a bit of money to make these repairs.
