2002 Chevrolet Impala: doors won't lock, open or latch

Filed Feb 20, 2018 · Electrical · 101,000 miles · FL

The power door locks are not working. When you try to start the car, the security light comes on and the car will not crank or turn over. In the rare instance you do get it to start, if you turn it off, it will not start again (anywhere from an hour to two weeks or more). I have done my research online and there are literally thousands of people whom own gm cars that are having the same problem with no solution. I cannot get help from anyone and am frustrated beyond reason, so hopefully you can do your research and figure this out! I cannot depend on this car and I am disabled!

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 impalas. 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.

Electronic - first problem was airbag light staying on - after at least 4 trips to dealer - problem fixed - now radio is locked and somehow connected to door locks and security system - apparently this is an issue for this model and needs recall.

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.

Several times I would go to start my car and the security light would be on in the message center. The car would not start. It did nothing like a dead battery. I would wait about 15 minutes and try again. Sometimes it would start sometimes it wouldn't. It was doing this 2 or 3 times a week. On sept. 9, 2006 I came out from shopping and it wouldn't start. I waited for 15 minutes and still nothing. I did this for an hour. Then I called a friend to come and get me. I went back to my car which is a 2002 impala, the next day, still nothing. The next day, still nothing. I called a tow truck to the dealer to get it fixed. Also my power door locks had quit at the same time. I was told I had to give them $100.00 just to look at it. 3 hours later they called and said that I could pick up my car. Total cost towing $59.00, dealer $496.95. I am disabled and only get $600.00 a month from disability. Now I have no money for my living expenses for the month but the car is still doing the same thing. On the 1st of oct. I went out to start my car and guess what it won't start. Since this was a sunday I called the dealer on monday morning to tell them that it was not fixed . It was still doing the exact same thing that it was before they supposedly fixed it. By the way when they supposedly fix it they replaced the bmc. Now they want another $100.00 to look at it again. The part was guaranteed but not labor, I could not afford another bill like the last one, I just hope it starts when I go to the dr. It starts only when it wants to. My husband just had brain surgery, I have had 5 surgeries on my spine, I need a car that I can depend on to start. Never had a problem with it. I will hold chevrolet responsible if any thing happens to my husband or my self because the car won't start. After I took the car to the dealer I came home, looked on the internet under chevrolet impala 2002 and found 100's of service bulletins on the very same problem. Why isn't any thing being done about this.

2002 impala ls with serious electrical problems. The first problem started with the turn signals going out. Then the radio would not go off even when the keys were out and doors locked, and sometimes does not work at all. Automatic door lock no longer works. When trying to start the car, I have to turn the key several times and then wait for it to finally start. The interior lights flicker. The headlights don't always work - I try not to drive at night because I never know when they'll go out. The instrument panel works about half the time, so I don't know how much fuel I have or how fast I am going. The message display goes between "security", "high beam out", "service engine soon", when it's working. There seems to be a new electrical component that goes out each day.

I wanted him to check my driver side back door because it wouldn't open very easily at times, and the window to that same door would not open at times. Also, my trunk wouldn't open when one would use the trunk release button at times. I also had him check my dimming headlights, my steering which had a jerk in it when I went around curves, clicking sound in engine and an over all check since my warranty is about to run out in 1,000 miles. Turn out-after leaving the dealer my air conditioner was humming like a helicopter, my brakes were horrible and grinding and the car feels like it has no get up and go power. I took my car to brake check after leaving because when the dealer did the overall check of my car they said I needed a front brake job. And they wanted to charge me over 200.00 dollars. The dealer told me it was not covered under my warranty. Well brake check took off all four tires and found that my problem was due to left and right caliper problems on the inboard side and left rear hard wear problems and wear on the outboard side. The caliper is engaging but not disengaging and caused my pads to wear out and my rotors are ate up. The pads are not worn evenly which is definitely a sign of caliper problems. Also, the dealer upon the overall inspection of my car said that my intake gaskets were ruined and leaking coolant. They said they replaced them, however I am afraid that there is further damage to my vehicle that they are not telling me, just like my brakes. Due to the fact that steve at lone star told me that it was caused due to lack of oils changes and gil said it was a problem with the gaskets being improperly seated from the factory or just a defect in the gasket. Well is this why my car has no get up anymore? My car also made a grinding sound when hitting bumps under the right front fender area that nothing was done about and my headlight problem they said was due to a faulty battery cable.

Power door locks on my 2002 impala still are not functioning properly and haven't been since shortly after car was purchased. Supposed to lock when taking car out of park. Dealer has attempted to fix problem numerous times before , and it has been a temporary fix as the problem continues to resurface intermittently. This safety feature is not reliable.
