Chevrolet Impala: Problems & Solutions

    Bring it to your local dealer, they should replace your BCM modular for free which should solve your problems. The BCM controls low voltage stuff, my went bad and had the same symptoms.

    I am having a big problem with my Impala and I hope someone can help me since any shop I take it to has no idea what is going on.

    About 2 or 3 weeks ago my air condition compressor kept trying to turn on making a loud clicking noise
    Three days ago I noticed that when I shut off my car and openned the doors, the radio had stayed on. The next day the same thing had happend and I went into the grocery store for about 15 minutes and when I came back my car wouldn't start at all! My husband is a tow truck driver and I called him to come and get me and before I got off the phone I tried the car again and it started right up! But the Security Lock was displayed in the message centre.

    We took it to the garage and left it there overnight. First thing in the morning my car started fine, they hooked it up to the computer and it came back showing no error messages. They took it for a drive, it worked fine, my husband came and took it for a drive and it worked fine. I went to pick it up and it wouldn't start. The Lock was still on and the mechanic said that it was preventing the start up, but it still wasn't reading on the computer.

    We were able to shut off one of the main power sources to the car, re-boot and it starts up right away but only for one or two start ups and then the security setting comes back on and it won't start.

    I know some people suggested the computer, is there anyway that the computer itself can get checked out or do we just have to replace it and hope for the best.

    Did your car start up fine after sitting 8-10 hours? My car would start up fine, but if I stopped for an hour it might not start up..Will the dealer replace the bcm for free with 105 k on it?
  • kwhittumkwhittum Posts: 12
    Yes, my car started fine after sitting, further the clicking sound seem to occur more frequently when the outside air temperature was warm (> 75 - 80F). I would at least ask your local dealer, maybe there is a tech. Service bulletin. Dealer have the ability to do repairs "Goodwill" (is what my bill said) I'm sure they then are reimbursed by GM for the repair, which suggests they know they have a problem with these BCM's.

    Dealerships have limits to their ability to goodwill repairs. 105k miles is too many for a dealer to help. You would need to call Customer assistance and ask them for help. Good luck!

    Hi im new the site...

    I have a 2000 Impala LS 3.8L. The car has 140K miles on it...Good engine The problem that Im experiencing is: I start the car put it into drive, 1st or 2nd or reverse works fine..But after 5 minutes, I can shift into any gear and the car will not move...engine only revs up. I checked the transmission oil & the shifter cable...fine. During the first 5 minutes, I can drive anywhere no noises, transmission does not slip.

    I had the same problem with my 2001 LS......after 32000 miles......the reaction gear in the transmission broke..Shift the car into reverse or forward gear and the engine would just whine and then suddenly after a few seconds the car would lurch ahead or not move at all. I would shut the car off start it up and sometimes it would be ok but after awhile it got worse......I was out of time warranty but continually hounded the service manager and GM ....finally under goodwill GM went for half the cost.. (my cost $1300) the police Impala's have been plagued with the same problems, and many departments moved away from the Impala's because of transmission problems they experienced.

    We purchased our 02 LS with some 25 k miles on it. We have had numerous :) problems. We hadn't had it long when we had the tork converter replaced as the dealer said it was cracked, I only saw a small occasional drip. Not long after that we had trouble with the stereo over heating and the rear view mirror wouldn't dim. The dealer replaced the radio and said too bad about the mirror but it eventually started working again. The TCS has been a problem for about a year now. I saw on another post, the wheel hub bearing assy. has a sensor that may be the problem. Impala's seem to have a tire wear issue also. As I said at the top, about 25 k miles and the factory tires were so chaffed, they sounded like an off road vehicle and had to replaced them. We put T\A,s on it and have had to have them rotated every 3k miles to keep the chaffing down. We had a 4 wheel laser alignment at the time of the tire purchase. We know of 3 other owners with the same tire trouble. After talking to the dealer and GM they said the specs. are correct for this model. Wisdom is about to beat our love for this car. Great on the hi-way, mileage, comfort, trunk space, handling, interior room and so on. After reading some post here, it seems we are not alone. thanks for taking time to read this and hope no one is offended in any way as none was intended.

    I have a 2001 LS since new.........currently 43,000 miles. Original tires (wearing normal still another 12,000 miles in them no chaffing or uneven wear....rotated every 10,000 miles) The Goodyear GA's tires on the car are not the quietest tires, still the original brakes (probably another 15 or 20,000 left in them).....I know there has been a few with brake rotor problems but its usually attributed to driving habits. Did have a problem as reported in post #1232 other then that 4 years of happy motoring.

    purchasing 2005 Impala tomorrow, lease vechicle,from a dealer,16340 miles,clean,81/2 months old..warranty left. $16,000.
    Would appreciate any comments. ;) :D

    I've got a 2004 Impala with 48000 miles. I was diagnosed that the rear brake rotors are almost completely rusted through. The dealer has seen this in other W-body types in 2001 cars, but nothing remotely this new.

    Of course my discourse with Chevrolet got me no where. "It's normal wear-and-tear" - ya, but the car is one year old. Rusting that bad is not normal. I'm thinking about a class action suit.

    Anyone else experienced rotor rusting? Thanks!
  • bigtwigbigtwig Posts: 2
    You should be able to drive a new one off the lot for about that, especially with the new GM incentive available to everyone. Call a couple of Chev dealers in the area and start a price war.

    :confuse: What may cause the rotors to warp? I have 40K+ on my 2004 sedan.
  • chrisis30chrisis30 Posts: 20
    well warped rotors could be caused by many things I can think of four right off the top of my head>two footing when you drive (left foot on brake right foot on gas) will overheat rotors,also panic stops if you are following too close too often,also not using your brakes gradually and applying them all at once at the last second and of course not shifting to a lower gear upon desending a steep long grade. and there are probably some others that I'm missing. tell you the truth these days it seems the brakes are out lasting the rotors maybe the brakes are too metalic or the rotors are just too cheap but I guess we can't have both??although thats a real shame when you spend $30,000 for a car a you have to get the rotors cut at 15K
  • hchu1hchu1 Posts: 17
    To relieve your frustration, I suggest you buy a set of cross-drilled slotted and zinc plated rotors. They can cost as little as $150 per set of 4 or whatever your wallet can handle. If you work on your own car put them on yourself and cut the labor charge. I put on a set myself after having the same problems many on this board have had with rotor warpage. With the replacement rotors I feel as if the brakes work better than new. No more braking vibration or shudders. I hope this helps, good luck. :D
  • kwhittumkwhittum Posts: 12
    Does any ones clock consistently run slow by a two or three minutes? For the first three three years my clock was always losing time. I never thought much about it, but ever sense I had the BCM (Body Control Modular) replaced my clock has been keeping time! I wonder if there might be a connection to faulty BCM's and clocks running slow?
  • sportymonksportymonk Posts: 258
    One reason I am hearing more about these days is the mechanics not torquing the wheels on properly. Too tight and in the wrong order will do it apparently.

    My 01 LS had the rotors turned at 14K, replaced front AND REAR at 30K !!, turned again at 48K and turned again at about 80K. Brakes pads just replaced for first time! Have heard that the problem is they had to take the asbestos out of the pads and when they started making pads with high metal content, the pads are eating the rotors up. Have heard a lot of ofther reasons by mechanics that don't bear repeating but made me wonder about the quality of anything else they did.
  • sportymonksportymonk Posts: 258
    01 LS Outside rear door handle just half broke last night. Of the two rods that connect the handle to the inside mechanism, one is ok but the other is broke. Will extended warranty cover this? How much will it cost if it doesn't?

    Door wasn't used that much, compared to driver's door which is always used.
  • rodneysrodneys Posts: 2
    Simple question for you folks. I have a rental 2005 Impala and I can't figure out how to release the foot e-brake.

    Thanks in advance!
  • rodneysrodneys Posts: 2
    Nevermind, I figured it out.

    I've only seen foot pedal e-brakes with release handles.

    In case anybody else is as puzzled (stupid, actually :) as I was, just push the brake pedal down again and it pops back up.

    I have a 2000 Impala and had some of the same problems as you. They told me it was one of the coils gone bad, they replaced it and haven't had a problem since. Warranty covered mine.
  • dollangeldollangel Posts: 7
    Yes I think you could be concerned. My engine does not use any oil between oil changes.
  • dollangeldollangel Posts: 7
    Every Impala owner I know personally has had to have the transmission rebuilt or replaced. Costly if not under warranty.
  • dollangeldollangel Posts: 7
    I was told that when you have any problem and any warning lights come on it has to happen like three time in a certain time frame in order for your system to send out a code to be pulled from those crazy machines they hook your car up to. Check into it a little more before taking guesses and spending alot of money.
  • sportymonksportymonk Posts: 258
    Well, knock on wood but among my many problems with my Impala LS, I have 85,000 miles and the transmission has given me no problem. The front suspension creaks and groans and pops (Engine shims installed, hubs replaced); CD radio failed, trim on roof coming off, right rear door handle (the one least used ) just broke, rotors have to be turned every 15,000 and replaced every 30,000 ($500!!) but the transmission is ok so far.
  • dgonzalez13dgonzalez13 Posts: 110
    112,000 miles total, 5 accidents, driving from Brooklyn to Albany once a week for a few months a few years ago, and potholes galore in the 5 boros. Transmission is still going strong, knock on fake wood. I had the same rotor problems too for a while, then got em replaced instead of cut and have been ok since. Getting a used 2003 LS this weekend, hoping it's as good as my 2000 Impala.
  • canamguycanamguy Posts: 5
    Just an extra.. no problems what so ever with the tranny or the brakes. (knock on wood)
  • rusty13rusty13 Posts: 1
    Hello-new here. I bought a 05 brand new about four months ago, now has less than 3,000 miles on it. Several times when I have started it, car will immediately die-always re-starts fine. Almost every time I speed up, usually up a incline, it will miss (the kind you feel, not hear) and "hold back", have also been several times I will put into reverse and it will jert a knot in your neck, not to mention the loud sound. Gonna call the dealer but didn't buy extended warrenty (gut feeling is I should have gone with another car) Really worried. Any thoughts on this.
    Thank you in advance!
  • charts2charts2 Posts: 618
    Get your car back to the dealers could be damaging something the longer you drive it.....your warranty should cover any problems, you still have 33,000 miles on your original warranty with GM. You can buy an extended warranty with GM anytime during the first 3 years that you own the car as long as you are within the 3 years/& 36,000 miles......I am not a big fan of extended warranties.....they are very expensive, but to each his own!
  • dollangeldollangel Posts: 7
    You poor soul. I feel your pain. I too have had some of those same problems. My tranny was rebuilt at 96,000 miles.
