My 2003 Chevrolet Impala ls has had this problem for years and everyone else with the Impala have the same problem. Why is there no recall? the dealerships have been charging people $600 to change the ignitian that doesn't even fix the problem. That is what they charged me 3 years ago. The car will not start once in awhile and you have to wait 15-20 minutes for it to finally start. It started out every other month then every month then twice a month. Now in 2010 it happens 2-3 times a week for me. Here is one of the many forums about this problem 64.13.204.178/Chevrolet/Impala/2002/electrical/passlock_problem_wont_start_and_security_light_is_on.shtml

I own a 2003 chev. Impala, ls and cannot drive with the bright lights on as they only remain on 3-to-5 minutes and go out completely. This is very nerve wracking and dangerous. Thus, I no longer use high beam and was told a new switch for $500 plus installation was needed. This has occurred since I purchased with warranty left, but thought it was just a once or twice occurrence.

I have a 2003 Chevy Impala that has starting problems(no start). Since 2004, there have been at least 4 BCM and PCM modules installed on this car from the GM dealers in which I have all the paperwork for. For the first year, the security light would come on then car wouldn't start for 10-15mins. Then the second year car wouldn't start for 30-45mins. Take to dealer and they couldn't find any problems. So the third year, after missing alot of time from work, it starting doing the same thing and I had it towed to GM. They had it a week and still found no problems. Then the following week the same thing happened and towed again- this time they started throwing parts at it because they didn't have a clue( bill heard in plant city, fl). So after new parts, it ran for about 4-6 months and started doing the same thing. I again took to dealer and no problem found but they decided to put another BCM on it. Then it would work for a few weeks and then the security light, traction light, ABS light would come on and next time I try to start it then nothing would happen. So this is happening almost every other day now. This car has left me stranded so many times that I am sick of it and I keep putting money out for towing bills and all the GM dealer can tell me is to bring it in and they would look at it again. I have put out alot of money for bcms every year now and no warranty nor my money back for defective parts. I think GM has done a poor job at evaluating these concerns and do not care about the customer. Something needs to be done about this issue and a recall needs to be on all of the vehicles with the passlock II system.

2003 Chevy Impala 4 door. Whenever we drive the car at night with the headlights on high beams the go off completely. So when we are driving the speed limit like 65 it becomes very interesting. This happens about one minute after high beams are turned on. This has been happening since we purchase in February 2009. We want a vehicle recall, as there are many complaints on the webb. Does anybody have to die before action is taken by the gov or General Motors on this problem with the Impala.

The pass lock security light would come on while driving then it would not allow me to restart the car. This happen at first 2 to 3 times a month at first then the last three of four months it takes place about 3 to for times a day. First the security pass lock would come on then the car dash boards ant every thing else would work but I just could not crack the car. Then the pass lock security would make everything the car turn off the car would not make a sound. Then it started running my battery down. Then it would run down the battery every other day. This is a danger because it has left me stranded late a night and also during the day. I have missed work due to this defect. I hope Chevy will do a recall. I see that I am not the only consumer with this problem. Even thou no death or accident took place due to this defect this is still a serious matter due to the fact that this problem has cost me wages and rest. I a life threatening emergency this car could cost a life all because I might not be able to get it to start.

(1) nothing appears to lead up to the failure. At least there seems to be no rhyme or reason to it. (2) the failure is the car will not start at times. We bought the car used with approx. 26M miles on it. It did not do this for the first couple of years we had it, then it started it. At first we thought it was the battery since the car was about 3 years old at that time. That didn't stop it from doing it. Someone where we go to have the oil changed said he knew what to do when it does it which was disconnecting a battery cable. That seemed to work for awhile and then that stopped working. At first when it did it, it would only be approx. 15 minutes before it would start. Now it is up to over an hour. (3) the only money we have socked into it has been for a battery. From what I can gather on the internet, this is a very common problem.

My 2003 Chevrolet Impala has intermittent starting trouble. Sometime it will start fine and other times it wont. The dealership said it most likely the BCM or passlock system. This needs to be a recall. There is ongoing problems with all Chevrolet Impala for this issue. Stranded with kids all the time.

After changing my battery on my car I notice now that my lights flicker on and off. There is also a clicking sound coming from underneath the dash and sometime my car will not start.

I have a 2003 Chevrolet Impala with a 3.8 liter V-6. the car radio quit working and I had to pull out the fuse because it was sending strange error messages to the body control module. Now the BCM is having even more problems. The car turned itself of then back on while I was driving down the road. I pulled over and shut the car off. Then it would not start again. I pulled the fuse for the BCM an the car started and I made it home. What in the world did General Motors do to these cars. I have been reading numerous horror stories about their cars. Was there a recall to fix this problem or do I have to go to the dealer and spend a fortune to fix this garbage pretending to be a car. How can a car company get away with this poor quality control in this day and age? my security display now shows random errors like low fuel even after I filled up the tank. Not sure if any major damage was done to the car but now the transmission hesitates when it shifts.

I was driving my 2003 Chevy Impala and tried to signal a lane change and the flashers would not work for either direction. There was not any accident, but the situation was very aggravating. The car also has a history of oil seepage and it has only 70,000 miles on it. We bought the car 4 years ago at a used car dealer, and I change the oil myself every 3000 miles. The car is hard staring at times, and I had put a new battery in it 2 years ago due to the trouble starting.

I have 2003 Chevy Impala and has been failing to start for over a year. At first wait 10 to 15 minutes and try if it didn't start wait again and continue this until it did start. Then I found if you removed the BCM fuse and replaced it, the car would start. So I installed a switch to remove power from the BCM to reset it. Now depending on the outside temp. It takes 1 to 20 tries to start the car. This is very inconvenient and I feel dangerous because my wife primarily drive the car. I have read several forums about this problem and no one has been able to come up this a fix for this. I believe it should be recalled by GM.

The security light started flashing on and off, causing my headlights to flash while driving and causing the lights in my dashboard to flash also. It ended up stranding me in a parking lot because the so-called security feature on this car shut the ignition off and would not allow me to start my car.

My 2003 Chevy Impala security light comes on during driving car will stall or die causing me to have to cross traffic a T coast to get the emergency lane of road which is dangerous. Many times when I go to start vehicle it does nothing. After doing some online research I found that this a common issue with these vehicles. This is clearly a manufacture defect.

Car will sometimes start and often not, unsafe if going on a trip internet says most likely problem is pass key or BCM module....

- Hamilton, 00, USA

I have had numerous problems related to the service traction service, ABS, failure starting (pass/lock system), and the security light on for no reason. About 2 years ago I had the ABS and traction system worked on for a total of around $250. About 1 month ago my ABS and traction caution lights came on and have stayed on to present day.

Passkey theft detterent system fails not allowing car to start. There is no work around except to return car to dealership.

- Frederick, MD, USA

Noticed failure of air bags, door locks, radio, A/C, security lockout/ no start battery drained. I am ase certified and located the battery drain to the BCM (body control module). After replacing it, it was necessary to take it to the dealer to have it reprogrammed. At this time all functions (but the door locks) work. Of course the dealer rep says that the problem was pre existing as all the other functions work. I will now start looking into the cause of the door lock failure. Here's why I'm writing. These problems are huge safety issues not to mention the expense and extreme inconvenience and "down" time. As you drive, the car has no air bags, the door locks don't work and with my 4 door car I can't even lock my car to park it outside of an unlocked garage. I want this to known as the most unsafe vehicle I have ever driven.

I have a 2003 Chevrolet Impala. I have had it for a couple of years and within a few month of getting it my door lock fuse started blowing. After a couple of months of replacing the fuse every other day my security light started coming on while I was driving. During the past year when I drive the car sometimes it does good other times my headlights flicker on and off and go completely out which has almost caused me to have several accidents, my radio turns off on its own. There are a couple of fuses that blow that causes my car not to start at all, my interior lights flash on and off. My car has a mind of its own.
