2002 Chevrolet Impala ls 60,000 miles leaves wife stranded due to some security device that does not allow the vehicle to start, no warning signs other than a security light that is displayed for no apparent reason while driving. I have researched online and it seems as though this is a common problem with these cars. The repairs are expensive and don't seem to be a reliable fix this is a safety issue to me. GM should fix it, as it is a obvious design flaw.

My 2002 Chevy Impala has a random issue with starting and has left me stranded several times. One time the car quit running while driving leaving me with no power steering or brakes going down the highway! then would not start again for about 15 minutes. On the internet I see where there are thousands of ignition switch complaints on this and several other GM models. This is obviously a GM issue that they have failed to address. Leaving someone stranded or even worse stalling while driving is a safety issue. I live in Ohio where it can easily get below zero in the winter if my car leaves me stranded, it could be very dangerous.

Car will not start sometimes. Battery is fine. Lights work, locks work, etc. Battery was replaced twice before realized it was not battery. Have to wait 10 minutes and then try again to start car. Usually starts after 10 minute wait. If not, have to wait another 10 minutes. Security light comes on for no reason at times and then goes off.

Several Chevrolet vehicles in the 2002 range (including my 2002 Impala) have a design defect in the body control module that causes a failure in the passlock security system. The failure is intermittent and unpredictable, but causes the car to either not start, or stop running. Once the BCM fails, the computer must be restarted to start the car- this means sitting in the car for 8-11 minutes waiting for the security light to go off; regardless of whether it's 110 degrees out, or 10 below. The problem is widely reported on auto forums, so there is no way Chevy doesn't know about it. There are even companies willing to bypass the security system (by cutting a wire from the BCM, and routing a wire from another source with an appropriate resistor) to eliminate the problem. A dealer will replace the BCM, but the replacement is the same design as the original, and is just as likely to fail (not to mention running $500-$800).

1999-2004 Impala have a problem, trac off, service traction system and ABS lights go on. This deactivates the anti-brake system and can be very dangerous when driving on a slick road. Also without traction control your car will not accelerate, turn or brake and will skid. What happens is GM used cheap wiring or cut too short and these wires corrode. This problem is an easy fix, GM is aware of these problems but refuses to do anything about them. It would be an easy fix but the only thing about that though is that you cant just replace the wires, the wires are sealed in the hub assembly, so you have to replace the entire hub assembly. Also there is a problem with the passlock feature, passlock was created to prevent thieves from stealing your car, not to prevent you from driving it.passlock can cause the vehicle to lose power while driving on the highway and may stall. That in itself is a major problem. I suggest you force GM to do a recall before people die because of negligence. And if they refuse to comply, just slap them with a major lawsuit.

2002 Chevy Impala ls on many different occasions will not start. I have been researching the problem online since I have sent my car to my mechanic twice for this issue, and he has no idea how to address the problem. I've found hundreds of other Impala owners who have had the same thing happen to them, and many cannot understand why a recall has never happened. On this link, there are over 150 similar complaints listed of over 2002 Impala owners. Please make GM have a recall for this recurring problem that has also been a safety issue since some Impala owners have been stranded in bad weather conditions: please take the time to look into this issue on 2002 Impala. Thank you for your time.

I purchased a 2002 Chevy Impala ls in November of 2008. The security passlock system begin acting faulty in may of 2008, faulty as in the car won't start if it's too hot outside, when U turn the ignition in the on position you hear sparks and static from the wiring when the security light is on. You have to basically perform magic to get the car to start. And the could take up too 4 hours of sitting wherever you are. GM is practically aware of this very irritating and costly problem and should be held liable.

It started back in 2002 a few months I purchased my 2002 Impala. It was a used car with 15,000 miles. The check engine and low coolant light came on. Took it to the dealership and had the water pump and low coolant sensor replaced. A week later, low coolant light comes on again. Again took it to dealership and had to replace another sensor. That happen 10 times during the same year. As of now, July 2009, the light is still on. In 2007, my vehicle started to run hot. Was told I needed the manifold intake gasket, thermostat and hoses replaced which would of cost me over $1000. I couldn't afford it. I got a local mechanic to replace everything which he charged me $300. Just recently, I've been having problems starting my car especially after I drive it for a while. I'm a single mother who goes to school and work and this is my only means of transportation. This car has been giving me the blues the past few years and I'm sick of it. All this started with about 150,000 miles and currently I have about 168,000 miles. I will get a better, dependable vehicle later this year and I won't buy another GM vehicle again.

2002 Chevy Impala 7 times in 3 years I had security light issues with this vehicle leaving me stranded I had paid to have this vehicle until I through a fit in December of 2007 GM honored it because the part they put in was faulty. Here it is a year and a half later and I have the same security issue this time it cost me 510 bucks and some change. The car has 50 thousand miles. I will never buy another Chevy period. Since I have been doing many searches on this issue and now see that I am not the only one with the same issue.

I have a 2002 Chevy Impala and I have been having problems with my BCM (body control module). Sometimes when I start it up it will not let me start it up because that security system comes on. It also failed in general yesterday which I figured this out because I had unplugged my BCM and reconnected it and my car started up just fine. I went to the dealership to find out if it could possibly be that because I am not GM certified. But like any other place they gave me the run around and told me it can be something else and something else but I'm pretty sure its this. I have done my research online and most people have problems with there BCM, once they change it the problems go away. I believe GM should fix this problem for free because its something that only happens on Chevy's. I know this because I owned a 2001 Chevy Malibu and it used to do the same thing. This also has happened to me more then ten times in the past four months and its ridiculous. Now I go to see if I can get it fixed and they also told me that if they program it and its not that my money is not refundable and I'm stuck with a car that doesn't work and I loose out around 300-400 dollars.

Impala 6-cyl

2002 Chevrolet Impala ls/ 3.8-V6 the problem started with the ignition switch. It caught on fire. Took in to dealer, after it was replaced, another problem surfaced.. we keep getting the run around at the dealer..the car intermittently starts. When it wants to. The dealer that I brought it to said he was 80% sure that it was my BCM (body control modules) and he would have to reset my radio. The two repairs would run me about $1,200 and that isn't even 100% guaranteed that it would remedy the problem. What a way to conduct business. I can't believe there are no service bulletins on this.. in doing some research I see the problem is quite familiar on models of the same platform.. I'm at my wits end with this problem.. the car does finally start after sitting there for 10 min or so.. my issue with this is! I'm happy to pay if the problem went away but non of the G.M dealers I've contacted seem to be upfront regarding the matter, and I quote "bring it in we'll take a look at it" that's it! how about fixing it? I reply.. "well we don't know what's wrong with it".. the car does not do it all the time, but a lot of the time.. usually at the most inopportune time. The problem does not seem to be a new one it's happening a lot.. I'm sure a design flaw. I'm just scared of another fire.

Passlock system failure on 2002 Chevrolet Impala ls. My wife became stranded late at night due to the passlock system failure, vehicle would not start.

I have a 2002 Impala. The problem is with the electrical system. Specifically, the security light comes on, the door lock fuse blows, clicking noises from the passenger side fuse panel, and on multiple occasions the starter will not turn when the key is placed in the "start" position. This issue can easily be found elsewhere on the internet. We have had this car since Sept 2003. No issues until the last 7 months. The problem has become more frequent and sometimes disconnecting and reconnecting the battery several times fixes the problem. It is a very frustrating experience having to "reboot" the BCM by disconnecting and reconnecting the battery all of the time. My concern is eventually the electrical system will completely fail or worse cause an electrical fire. Others who are dealing with the same issue are spending hundreds of dollars in parts replacements only to have the problem return a couple of weeks later. This "security" problem has to somehow qualify as a recall with Chevrolet/GM. Currently, I am still able to manipulate the electrical system in order to get the car to start. I'm really not looking forward to taking the car to the dealership and be charged enormous fees for parts and labor knowing that this problem will return later on like others have experienced. Please find a way to force GM to do a recall on this problem.
