Alternator/generator/regulator problems of the 2002 Chevrolet Impala

For awhile my car has been having starting problems, at random times it does not start and it takes ten minutes from the first time I turn the key to start. Recently it started shutting down (as far as dashboard functions and the motor kills) bounty for a brief moment as I am driving I noticed it does it whenever I used the turn signals and it also makes a buzzing type noise when I use the turn signals then it goes away. Now my car won¿t start at all, ive had my battery and alternator both tested and they both came back fine.

Security passlock not allowing car to start. Fuel regulator faulty not getting fuel to start car. Once I get vehicle started I can cut car off and try to restart, car will not start. Issue needs to be resloved.

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.

I purchased the vehicle used from another dealer in 2003. I started experiencing problems with the security system in November 2005, it would not start sometimes light would flash and after 20 minutes it starts. The problem went away until last November, and then it would do it about 2-3x a week. In February 2009 I had to replace my lower intake manifold gasket, water pump and battery. The summer 09 I had to replace the radiator due to a hairline crack in it. The security system starts to intermittently not start the vehicle again in late Sep. 09 about 2-3x per week. In Jan. 2010 the vehicle doesn't start for me one day after coming out of the grocery store for 25 minutes. Since then it does it every morning when I go to take my child to school and I have to wait 10-20 minutes. I took the vehicle to the gm dealer and was told they weren't familiar with this problem and I needed $950 for parts and labor to replace the ignition switch and the bcm. I had the ignition switch replaced by another mechanic and that was not the problem and the vehicle is still doing the same thing. It's frustrating for me and my child. It's scary and dangerous. I'm so afraid that one day or night it may not start and I'm stranded in the streets and may be subjected to a crime or death. I don't drive it at night unless it's an extreme emergency now and this is such an inconvenience. I have to pay for rides at times to get my child to and from school when this car decides not to start so my child won't be late for school or getting picked up from school. I've also had to replace my windshield wiper motor and my driver's side door window regulator.

On a 2002 Chevrolet Impala, the security light comes on while driving. Following this event various electrical abnormalities occur. Dashboard warning lights all flash together, dash goes dark. Sometimes when you start the car the security light comes on and the headlights flash as if they were icc flashers. There are numerous complaints about this on the internet. Chevrolet doesn't seem to have any finite fix for this and randomly replaces the bcm and ignition switch as possible causes. Most people report having the exact same problem over again several days later??? due to this erroneous reporting I thought I had a battery problem and the garage changed my alternator. At a cost of $306 dollars. Which I now believe was totally un-necessary.

Car would not start. Thought it was the battery or possibly the alternator, but it turned out to be a failed body control module (bcm). Our car had only 46,000 miles when this occurred. There should be an official recall on the bcm given the numerous bulletins and complaints concerning the bcm before someone's loses his or her life as a direct or indirect result of its failure.

My 2002 chevy Impala LS has had a problem, since buying it in may 2002, with the headlights dimming to the point of cutoff then coming back to full intensity in a rapid fashion. I have had the alternator, battery, belts, cables/wires checked but to no avail. I do notice that if I accelerate sharply, over 3000 rpm, the problem goes away for a while, suggesting there is a charging problem. This problem is intermittent, but is increasing in frenquency as my odo reaches 23,000 miles.
