I have not had an accident. I have had this car little over a year and had nothing but problems with it. Started off security light flashing then not starting I could unhook battery and reset and it would start. Lights would flash interior lights stayed on then didn't work voltage meter would bury to 0 but battery was fine air consign will not work when this happens door locks do then don't work blows fuses trunk will poc open radio will lock headlights flash t I ll I put manual lights on then automatic would work later. Security light flashes a lot of the time all these things start acting up and it continues to get worse. Sometime car will jerk and I have to reset by taking cable off then it works fine. I have kids and I do not feel very safe b in this car. Some of hard working single parents can't afford to spend 700 here and there from trial and error when it seems a lot of models from this year have the issue.

2003 chevy impala will not start. The dealership states it is a bcm problem. The remote installed on the car fob does not work and has never worked. Doors will not lock and the trunk will spring open when traveling down the road. Since the doors and trunk do not lock, there is no security on this vehicle. And again the car will not start. I have replaced the battery and alternator and the car still does not start.

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.

Security light would come on intermittently, door locks won't work, sometimes car wouldn't start. Security system is bad. Had to have a new ignition switch. Car still won't start. Now needs a body control module. Car still at mechanics. I have been without my car for 60 days. Unsure what bill is up to. Car would start overheating. Occurred 3-5 times before it was diagnosed and fixed. It was the lower intake manifold gasket. Replaced it for around $600.00. Headlights go out while driving. Mechanic and dealer has never been able to figure out why. Nothing has been done to fix the problem. Car would start knocking and ride rough to the point that it couldn't be driven. It occurred 2 times on different bolts. Rocker arm bolts were blown out of the head. Fixed for $300.00 each time.

Dt*: the contact stated the vehicle is equipped with automatic door locks. This feature locks the doors automatically when the vehicle is put into drive. Due to a failure in the automatic door lock, the doors must be manually locked. The vehicle has been inspected however the problem cannot be corrected. Also the keyless entry has been taken to the dealer 5 times for reprogramming. This only corrected the problem for a short period of time. Updated 4/6/2006 -

Dt: the contact stated the door locks were making a clicking noise and the doors would not lock. When he tried to lock the doors, they would slowly unlock. The battery died before he took the vehicle to the dealership. The dealership found the bcm, and the battery needed to be replaced. They state it was because the vehicle was not driven enough.
