Factory installed security system won't let me start the car, I have to wait anywhere from 15-45 minutes before it starts, and that is not safe to be stranded with the family. I'm not the first person with this problem, and I hope you can do something to help me solve it. Thank you.
I own a 2002 Chevrolet Impala. While I was driving 50 mph, the headlights malfunctioned when switching from low beams to high beams. The manufacturer was notified, but offered no assistance. The vehicle was not repaired. Next the car doors would not lock. Ordered new body control module and had it put in and reprogrammed at dealer. Worked for a week and while in drive thru and shut car off when tried to restart car it would not restart but start throwing a bunch of codes. Sat for awhile found second set of keys put it in and it started. Apparently the security system would not recognize the key when it was inserted into the ignition. This locked the contact in the vehicle and prevented it from starting. The vehicle is now in the shop. I have found over 1,000 complaints of the same nature with this car. In 2004 I had new head gaskets put on due to the coolant and was suppose to recoup some money. I put in claim and never heard anything. Now turn signals work intermediately. This is a very common issue with Impala. Very dangerous when I signal I don't know if it is going to work. I have almost caused multiple accidents because of this issue. I complained multiple times to the dealer but they claimed nothing was wrong. As soon as I hit the 100,000 mile.
Hazard flasher switch is bad. The turn signals will go out intermittently. If you press the hazard buttons over again the turn signals work again. This has been happening since 2012 when my vehicle had 70,000 miles.
The contact owns a 2002 Chevrolet Impala. The contact stated that while coasting, the pass lock security warning lamp illuminated and the vehicle stalled. The vehicle was restarted a few times before it began to function normally. The vehicle was not repaired or diagnosed. The manufacturer was made aware of the issue. The approximate failure mileage was 109,000 and the approximate current mileage was 111,500. Updated 9/17/13
I put a new fuel pressure sensor in and now my 02 Impala wont start and not getting any power to fuel pump now, we are a car lot and this car has been sitting unable to start now for over 2 weeks, had many certified mechanics from our area observe the problem, including 2 certified Chevrolet mechanics, and none have come up with a solution. Just don't make sense, I am sure Chevrolet is aware of the problem so please let me know what the problem is so I can have it repaired so we can sell the car.

Safety flashes on dashboard and car will not start for 10 to 15 minutes. It happens totally at random times in all kinds of weather. Disconnecting the battery does not help nor does resetting a fuse with a kill switch. This is a widely known problem why isn't there a recall" I was told from a dealer it was a computer issue and could be fixed for around 1000 dollars. I want to buy american cars but do I have to suffer because of this choice" what an awful inconvenience.

At 10:00 P.M., driver started the vehicle (cold) and pulled away from curb stopping at a stop sign 100 feet ahead.

Driver proceeded to take a right turn onto a main road when the driver's side head curtain airbag inadvertently deployed from the driver's seat back. Driver immediately stopped the car and pulled off into a parking lot to call for assistance.
The passlock system has been failing me since 2005. The car starts when it feels like it. I have been stranded for 6 months, late to work, and mentally stressed thanks to this problem. Everyday for the last 7 years I have experienced this problem. In 2005 I had the BCM replaced, and GM blamed the problem on the viper alarm system. As of last week General Motors cut a new key, because the old key was stated as the problem. Now that the problem still exist GM informs me that I need to replace the ignition. This has to be a form of rape. I am a veteran, university student, and a part-time worker, so my vehicle is very much needed. My family and friends have to continuously watch me struggle due to this vehicle issue. I guess this is the thanks you get for being a hard working american.
Parked and turned off car, gauges, locks and lights went crazy. Car would not restart and electrical system continued to go crazy eventually the battery exploded and everything turned off. Dealership determined it was the BCM. 6 years later BCM is bad again.
Problems began almost immediately with digital gear indicator, dash, and other lights going out and coming back on. Got no satisfactory response from manufacturer and now cluster has gone out, switch out, low coolant light stays on. At times acrid smell in vehicle.
My turn signals work intermittently. Sometimes not at all and sometimes have to activate flashers on and off. Sometimes lites won't turn all the way off when I park they will make a chiming sound and I will turn them on and off til it stops.
For the past 2-3 years the security light will come on and flash about 10 minutes. During that time I have to sit with the key in the ignition and the ignition switched back until the security light stops, which then the care will start. About a month ago same constant problem except now after the security light stops flashing car won't start at all. I've gotten new battery and had alternator checked and both are good. The security pass code dealing with the keys or some mess I was told which will cost $500.-$600. Omg!!!!! really. Is there a recall or something for this. GMC please do better. Last american made car that I will purchase.
While driving at night on I127 highway, with my dim lights on and cars passing me, my dims go blank. Nothing. I had to quickly pull over and make adjustments to find the problem. After about a dozen episodes of these I find that my bright lights would still operate. After I'd get home I would shut the engine off and wait a few minutes and restart the engine and my dims would come back on !!!!! I have cleaned the little signal switch on the front dash but they still go off at any time of the night. I have come close to a few accidents. Please help ! I have talked with several mechanics and rookies but they were stumped. This is a safety issue and should be addressed.

Went to turn on the car; all lights locks radio windows worked. When I turned key to on position car would not turn on. Security light and check engine lights would come on. Car wouldn't turn on for ten minutes then it turned on. Also, while driving security light will come on and stay on until car is turn off and back on. Sometimes security light will stay on. In addition, to security light and car not wanting to turn on, turn signals will randomly stop working and I have to turn hazard lights on and off to get turn signals to work again.
