The transmission shift sensor has had to be replaced 2times in the past 8 year due to it being faulty. I am not sure what kind of a safety issue this could be but it really starts just randomly jerking into gear for no reason, I had it replaced 8 years ago and now again it is getting done, on top of that the ignition pass lock sensor has been causing the car not to start and from everything I have research this is a problem on GM cars from 2000-2004, I filed several complaints on car and you can clearly see there is a problem. It's going to cost me over $1100 to get theses two things fixed. I am very upset that Chevy chooses to ignore these problems. Over the past 4 months I have been stranded over 10 times because my car just wouldn't start. It took the shop a few days to even diagnosis it because they had to get them both to act up due to the computer not storing seems to me there is some electrical issues with this year but GM chooses to ignore these complaints

Vehicle stalled in traffic on various occasions, had it towed to local mechanic twice. On other occasions he provided advice to circumvent the problem, most occasions was to wait, remove and reinsert the key and start the car. Took the car into the local dealer (now bill kay), they advised that the ignition switch would have to be replaced (at an exorbitant cost to me). I had our local mechanic replace the switch, and it's been fine since. The problem is that I have two key for the car, one for the ignition switch and another for the doors and trunk. When I received the recall I contacted bill kay, relayed the specifics of my issue, and advised that I was not seeking reimbursement for all my expenses, but would appreciate them rekeying the vehicle so that I could use one key for the ignition, doors and trunk. They advised that this recall did not cover the ignition, and provided no resolution. Have contacted them several times with the same result.

The vats system will not let me start my car for 10 to 20 minutes. The system has broken down and my thinking is that GM should have a recall to fix the issue.

When you try start vehicle security light comes on and vehicle does not start. There are many reports of this issue noted online and customers are spending money on batteries and other parts without a fix. GM needs to fix this issue seems like many notes are indicating disgust with the company not responding to this issue.

I was going down a steep hill - warner hill road - stratford ct. The car battery light came on and I lost power - including brakes. I was able to use the brakes but they were extremely hard to push but they worked. Luckily there was no cars in front or back and the traffic light was green. I was able to coast across the intersection into the sikorski aircraft plant past the guard and was able to stop. I turned the ignition switch and the car worked fine. This car was recalled for ignition switch problems and all the dealer did was to replace the key fob with a lead weight. I believe that they should have replaced the entire ignition switch. Please let me know if you have any information that the ignition switch should have replaced instead of just a key fob replacement which did not work.

I was drive home from work at night and my security light came on my car. The next thing it was off. While I was driving to work after leaving home the light came back on and stay on. I got to work and look in my GM manual and seen that I should take it to a dealer. I went to my car after work to go home the light was off. I stop to get gas. My car would not start. Nice man came and said lets disconnect the battery. He did. My car started. I was ok for threes day then the light came back on and my car would not start. I had a recall on the ignition switch in Sept of 2014. Took it to the dealer they only fix the key. I took it to the dealer today they had to fix a part on the ignition switch. Please ask that there is a recall. I dont feel safe with this car. I can't afford a new car. I scared that this car could stop running while driving it. Thank you

Impala 6-cyl

I turned the key to start the car and was driving and my gas hand, speedometer and oil indicators just fell to the bottom of the circle. Instead of showing me the amount of gas I have the red needle falls behind the "E". the same is true for the speedometer, the needle just falls to the bottom, and the cold/hot indicator is at the bottom of the panel. Isn't this an electrical problem?

Come on now, I see the complaints on a bunch of things that is wrong with my 2004 Impala. An there is more than one person saying it. There seems like there is a serious problem here that you guys seem to be ignoring an refusing to fix. I think its about time for some people to get together and file some kind of lawsuit against you guys if you don't address these issues. Now for the same complaints for my Impala, number 1 it does not like to start sometimes and then I have to wait 20 mins to an hour just for it to finally start. Number 2 the security light stays on. Number 3 the gages to my speedometer and gas move all over the place and doesn't give me the accurate reading. Other experiences I've had noticed is that my brights don't always like to shut off the first time, the car pulls mainly to the right, but also back and forth. And all the buttons and light to my radio works but no sound comes threw. I haven't experienced any of the other things in the complaints yet but these ones I have an they need to be addressed like I said before something is done about it by the people. Thank you
