Impala LS

  • 119,000 miles


My 2002 Impala LS first encounter with the electronics was a hard shifting transmission that would clear by pulling over and restarting. That problem seemed to clear up on it's own but then I started blowing fuses for the electric door locks. Next the security light started coming on but was only annoying and cleared when restarted. This progessively got worse (about the same time it was getting hotter outside) and would turn the security light on, cause a relay switch to click (right side dash) and make the daytime running lights turn on and off as well as the A/C compressor. Occassionally this will worsen to the point of the battery message coming on and when the ignition is turned off the headlights and tailights stay on until the battery is disconnected. Another intermittent problem is that the car will not start at all and the "locked" message comes on the radio which indicates the passlock system didn't want to be left out of the fun. Of course letting it sit and think about it for 15 minutes allows me to start and go. I'm going for a new BCM but from what I've read here and several other boards, this may or may not solve the problem. I suppose I should also have the ignition tumbler checked as well as have a new key made (bad chip in the key). Those seem to be the most common attempted fixes the dealers do although I'm not convinced there isn't another underlying problem... a ground or short possibly?

Impala LS

The car would not crank. Not even click. There seemed to be plenty of juice in the battery, but put it on a charger for 45 minutes anyway. Tried to start it after that, but nothing changed. Got the car into neutral, and then it started. Seems OK today. About a week before, the SECURITY light came on for no reason and eventually went out. It has not reoccurred. Is there a link? Not sure and I suspect that the Chevy dealer will not know either. At 50-60 bucks per hour, I do not feel comfortable letting them dork around with my wife's car since if there is no "code", they will not know what the problem is. If anyone has a similar problem, please let me know if you can get the car to start in NEUTRAL. Did mechanics seem to KNOW MORE prior to the use of onboard computers in cars? Or does it just seem that way?

I'm having same problem as many owners. Not starting. Nothing happens when key is turned. Taken to dealer twice and told might be, passlock system, ignition switch($400 if replaced). Shortly there after starts fine. Dealer said only drawing 3 milli amps current. Ask them to check history codes and they found none. Dealer had 3 days and said can't find anything because it started fine when they tried.

Just like the others a real pain in the AXX. Really inconvenient if you have to go somewhere and the car won't start. Happened several times. First couple of times would call Triple A. By the time they got here the car would start. Felt like a real jerk.... Dealer wants a $100.00 just to look at the car. How can they diagnose when problem is so sporadic. One dealer told us not to use the remote entry which worked for awhile. Now we just use the key and it started happening again. Message center is all messed up. Get different messages all the time.............. Chevy is no help.....................

Impala LS

I join the other two people as far as the car not starting. Very weird.... runs great and then all of a sudden it won't crank over. I have not had the battery changed nor have I went as far as to take it into the dealership. I did however, call GM with my problem and they informed me that it could be numerous things and I should take it to my local dealership. GM had no prior complaints to this problem. This is very frustrating and I as well as the others have to wait 30 minutes and then it starts just fine. Also, may I add everything else works--it just doesn't want to start sometimes?? If anyone has a solution please advise.

This is a really annoying problem, just when I have five minutes to get to work and be on time, the damn car won't start, due to the security lock out, I have to wait 15 to 20 minutes to start my car. GM really needs to recall this piece of crap.

First time it happen was under warranty in Little Rock, Ar Dealer gave us a story of cut wires and we beleived the story. It has happen many times since and the solution that works everytime so far -set parking brake turn ignition key on for 3 minutes then off, do this a total of 3 times on the last time watch the flashing security light - when it stops flashing you can turn off your ignition and bach on and it starts. Was told by a mechanic at a dealer who denied GM had a problem. Showed him all the problems found on the internet and he admitted GM had a problem and stated to apply the parking brake and with a stopwatch time turning your ignition on/off 3 times for 10.5 minutes. This reset the security system.

Impala LX

  • Automatic transmission
  • 54,000 miles

Security Light on the dash board comes and goes but this means the car will not start for at least 20 minutes. I called local service however they indicated that this is a dealer issue. The GM dealer with inconvenient hours, charged me $100 to say their tests show error codes. For $300 I could purchase a part that might work if not, pay an additional $500 for another part that SHOULD fix the problem. The dealer's hands were shaking nervous with the $800 figures on paper. I walked away from this shocking experience. The dealers know this is a recall issue yet they will not admit it or help in any way except to take customers money and await their sale of the vehicle. I have yet to come up with a solution to the problem. If anyone finds one, please let me know, the winter cold makes waiting 20 minutes for the car to start more than sad. I will never ever buy another Chevy!

Impala 3.4

  • Automatic transmission
  • 107,000 miles


The security system constantly activates and locks the fuel injectors so the car won't start. Took it to the dealer and they were going to charge me over 100.00 just to look at the problem. This has become a huge issue since we have two newborn children and live in the wintery midwest. At times it takes up to 30 minutes to have the security light stop flashing and then I can start the car. As I have read above there has been little if any sympathy from Chevy!

Impala LS 3.8

  • Automatic transmission
  • 85,000 miles

I bought the car new and as soon as the GM loan was paid off the security light would come on about 10 minutes into driving. The light will be on and change to battery light, then change to service engine soon. I have had 2 times of not starting. First time I waited 30 minutes and it started just fine. 2nd time I opened the door and it started. One time of the battery going dead. trunk wil not open when car is in park. Door chime will continue for 30 seconds after closing door.

Took car to dealer and was unable to verify the problem, no codes were set. told the dealer the headlights would go out if you used the dimmer while driving.. Dealer did find the multifunction switch was bad and replaced it. Was told that should correct the problem. 10 minutes down the road, same problems.

Cost: $ 200.00 for diagnostics

550.00 for multifunction switch

I will think long and hard before buying another chevy

From reading the reports, it appears this is a common problem with this car. Since this security comes as standard equipment, GM should pick up the repair tab or disclose a procedure to disable it.

This is my second posting about this piece of crap. I had the body control module replaced and it's been fine (for this problem only, as there are many other unrelated problems) for a few months. Driving into work this morning, 11/8/06, the freaking Security light came on AGAIN! I have been having so many problems with this car I am about giving up hope. If anyone has any clue as to why this keeps happening, I would really appreciate an email (use the Send Comment link below). Thanks!

all of a sudden car wont turn over at all. turn ignition, nothing happens, no sound. battery checks out ok. security light has come on prior. never know when it will happen!! will start later but very much a problem as it can leave you stranded.

can lock and unlock car twice from inside and turn key on and wait at least ten minutes then turn key off and on again and will start. this should be a recall item from Chevrolet! costs $400. to fix and could happen again then!! has anyone had it fixed? if so, what happens then?

Car wouldn't start. We disconnected the fuse for the security system. Lights inside and out flashing continually, security light on constantly. Took it in to the dealership where purchased. Told it was the "Receiver" ($189CDN) that needed replacing. Picked it up, same problem. Did some net surfing to find others with same problem. Suggested BCM solution to mechanic. They weren't sure and didn't want us out anymore money - right! Still waiting to hear what they can do after paying $400 dollars for absolutely squat.

One day the car wouldn't turn over. I checked the fuses and relays, pushed them and then it started. I had it happen again, and now the security light is on. I started using a new key since my old key was having problems turning (Which I don't think have resisters in it in the first place) and replaced the fuses and disconnected the battery, but it still shows up. I have a feeling the computer in the car is not working.

At first, the electric locks quit working. Then the battery was dead one morning. It is impossible to turn the security system off. The car thinks it is always locked, so if a cat or varmint runs under it, the alarm goes off or the lights come on and stay on until the battery is dead. Battery is usually dead in the morning if it is not disconnected. Have an appointment at Chevrolet dealer next week to try and fix. I was hoping to find someone else with the same problem that could shed some light on it and save me some money.

This is really atarting to get to be a real big pain. I go to my car to start it then the Security light comes on and it will not start for 10 minutes. It is right down to the second. I have been told to put the gas pedal all the way to the floor when the car is off and this should reset the Security system. Nope does not work, I have taken it to a couple different places and they could not find the problem. So if anyone knows what the problem could be please HELP!!!

This is what I get for buying a Chevrolet, again... the shift interlock on the automatic on my Monte Carlo (same as Impala) stopped working and was replaced at 30000 miles. It went out again a month ago and caused the battery to drain overnight. Turns out it was not requiring the ignition to be completely turned off and the key could be removed partly in the acc position. The security light would come on when the car was started if there was juice left in the battery.

Had to go to Vegas for a flight Returned home today after a week and there is a ticking noise in the dashboard, the security light is still on, and the a/c does not work. Drove it a few miles, restarted it and everything works??? What's with this??? Then went to visit my daughter in Vegas and before heading back to Utah and the next time the headlights start flashing when I start it up. Decided to give it a night's rest and head home tomorrow... hopefully it does not break down in the middle of the desert. Sure not going to replace it with another Chevy.
