Unknown reason as to why the directionals on my 02 Impala work intermittently. This first occurred approximately 4 months ago with average occurrence of once a week. Now it occurs approximately once a day. Mechanic cannot find a solid reason as to why this is occurring and cannot replicate it at the time the vehicle is in the shop.

2002 Chevy Impala. The turn signals often fail to activate, creating a road hazard. Apparently a common problem on that time period Impala. Suspected a faulty multi-function switch.

The contact owns a 2002 Chevrolet Impala. The contact stated when the security light would illuminate, the vehicle would not start. The dealer advised the contact to wait ten minutes before re-starting the vehicle, but the vehicle could only be diagnosed while the failure occurred. The dealer advised that the computer chip potentially would need to be replaced but could not confirm if it would correct the failure. The failure mileage was 60,000 and the current mileage is 62,576. Updated 10/04/10. The dealer replaced the ignition cylinder. Updated 10/05/10

Went to work and when I went to leave the car wouldn't start- thought it was the battery and got a jump, wouldn't start. Had the car towed to auto place, and they couldn't find anything wrong, then after that the car has left me stranded and unable to get to work its shut off while driving- the security light was on, after the many complaints to Chevy- they wont assist with the repair of the pass lock security system for the simple reason its out of warranty. Its not a maintenance issue its a mechanical issue. Its also a safety issue. The car just shuts off as if someone is stealing it. How dangerous- on route 80 highway or any road for that matter, your car shuts off and your smashed from behind with cars piled up- someone will be dead andmany will be serious hurt. Or being stranded on a dark country road with no cell reception. This is a safety issue and after alot of research on this problem- GM"S response' sorry we cant help you- today Toyota recalled 412K cars, because of steering issue and was a safety issue. Nissan, Toyota, and Honda didn't need bailouts why because they stand behind their cars unlike GM- this is a big issue with hundreds of thousands of people complaining and GM as usual does nothing to stand behind their products. I will never again purchase a GM product as its a complete piece of garbage and the ones working for GM aren't any better. Let GM sink and go under, that way americans will have more reliable transportation and companies that actually stand behind safety issues with their cars. It amazes me how GM can take bailouts- to keepthem afloat but wont do anything to back their vehicles, sooner or later they will sink and they will all be sitting there dumbfounded scratching their heads wondering oh gee what happened, you didn't stand behind your cars moron that's what happened, and people went to more reliable companies. 13K for a 2002 Impala ls, guess its time to take it to the junk yard very unsafe and no peace of mind to drive the garbage.

The starter will not get a signal from the ignition switch. I have changed relays, ignition switch, starter, key core and passlock, all to no gain. Gave vehicle to they local Chevy dealership who changed to BCM and reprogrammed the security feature and when I went to pick it up from the dealership, it wouldn't start. The starter gets no signal about 90% of the times I turn the key. For the 10% it does work, there seems to have had no issue what so ever. It turns on smooth and runs like a dream. Yet it can be the first attempt or the 50th before the starter catches a jolt and starts the car, there seems to be no pattern. The security system works fine B/C we installed a simple push button switch to the starter and it worked every time with no trouble for a few moments till the gas was taken away and the car turned off. Bypassing the security feature and allowing a secondary ignition methos would seem to resolve the issue. I find this to be a safety issue due to the potential of being stuck out in the middle of an intersection if the cars happens to stall. Or if an infant was loaded into the vehicle and it would not start for 15 to 30 minutes, leaving the child with the risk of heat issues. The problem itself came suddenly without warning.

My 2002 Impala will randomly not start. The message center flashes security, battery and service engine soon. I have to unhook and reconnect the battery to get the car to start. I do not want to drive it alone, as I live in a big city and do not want to be driving and the car malfunction. I have read numerous accounts of this happening to people with 2002 Impala. I have asthma and one day I started to have an attack. Husband was going to drive me to hospital and my car decides not to start. I could have died waiting for him to reconnect the battery. I paid GM for a reliable car but got a car that will start only when it wants to. This is unacceptable. It's messed up that I can't drive my car for fear of it not starting and being mugged or raped while trying to unhook/rehook the battery. GM should be held responsible for this. They don't want to though because they make too much money fixing something that they screwed up. I will never buy a GM again. Toyota and Honda from here on out!!!

I have a 2002 Chevy Impala. The car behaves as though there is an electrical problem. My own research seemed to indicate a faulty BCM module. I took the car to a dealer and explained my suspicion and the odd intermittent problems, and they replaced the ignition switch and spent a lot of time trying to find a wiring problem. After 2 weeks they said they found the electrical problem and charged me $700. Now, a few weeks later all symptoms are back. When the key is turned on, the lights flash, truck latch opens and closes, and security light flashes. This is just 1 set of symptoms. This problem is very dangerous. I found this site while looking for help here: Please help!

Have 2002 Chevy Impala and the security passlock won't let car start, I have been stranded in many places. Had it checked out at 2 places and it all comes back to computer, or keys, we tried to have keys recoded but it still happens often. By researching on computer I see I'm not alone out there. What do people have to do to get GM recall this problem. It is a safety problem because it always happens when it either 5 below or 90 outside and have sit in car and hope you don't get mugged or robbed waiting for car to start or did of heat stroke or freeze to death. Is there anything we can do. Help please my car does this 4-5 times a day and no one knows how to fix it. GM need to step in and fix this defect.

Impala 6-cyl

We have experienced electrical problems with this vehicle for the past couple of years. We have replaced numerous parts dealing with the ignition/starter, pass/lock, power lock, and security system. We recently have been dealing with the car starting or not starting for that matter. At first, it was once in awhile and now it doesn't start 7-8X per week. It is extremely frustrating to have to constantly throw money at this problem. Once again it is going into the shop for diagnostic and more parts. This is a big problem and needs to be resolved. It is obviously a defect of some sort and needs to be handle accordingly.

My car, a 2002 Chevy Impala, has an intermittent starting problem since I purchased it at 2006. For every 2-3 weeks, it simply does not crank by turning the key. But after 10 mins, it starts again. I have spent a lot of money to try to fix this issue but it is unsuccessful. After searching on website, I understand this is a very common issue for GM cars and may be related to some electric security issue. Therefore, here I am filing the complaint.

Bought chev Impala 2002 brand new, no miles. 2005 began experiencing cooling system problems-running hot etc. Replaced radiator, flushed system, replaced thermostat, etc. Etc. Several times, body control units- lights and locks going crazy, hub assembly/tracking system problems- sounds and pulsating when try to brake or turn, high beam light won't stay on to this date. Experiencing smoke from hood-may be a leak which seems to be acommon complaint but dealer put dye in and said they don't detect a leak. No air-freon replaced several times.

02 Impala 3.8 engine would not start. It has done this countless times and I will have to wait 20 or 30 minutes for it to start. My battery is like new, and nothing is wrong with the starter, I've had it all tested. I've read it could be the passlock system or something called the tumbler. My security light comes on randomly even when driving on the highway. I've read that many Impala owners cars have cut off while driving on the highway and I'm hoping mine doesn't do the same. My car was a former police car. It now has about 112,000 miles on it. I hope I never had to go somewhere in an emergency or get stuck in the middle of no where at night. I've read several forums explaining how Chevy knows about the defect but will not fix it unless you pay about 600 to almost 1,000 dollars. But then when they claim it's fixed, the problem happens all over again. I read from a mechanic that worked for Chevy in the past, that they politely ignore complaints regarding this passlock and security problem. I guess no one will take it seriously until people start to get injured or even killed like Toyota drivers. Must we wait for the death toll to rise before the government steps in to act"?" policemen drive these cars although there slowly being phased out with the newer models. A policeman that cannot get to the scene of a crime on time because his car wouldn't start. I guess that's the headline were waiting for before Chevy or the government decides to do something about the passlock problem that countless americans are having and GM doesn't want to fix. This is why I will never buy another american car because the parts are cheap and GM could care less. The time to act is before major incidents happen, before people lose their lives, before 5 car pile ups on the highway, before an emergency that GM drivers cannot get to because there car will not start. Not after!!! that's Toyota's problem now. Advice for GM and the U.S. government - get it together!!!
