Chevrolet Impala: Problems & Solutions

  • WOW! after months of disconnecting the battery and removing fuses our 01 Impala has been depossesed. The BCM was the problem with the flashing headlights, and other fun stuff it loved to do. Now the only problem is the instrement panel only lights up when you turn the key then it goes dark again. It is not the bulb so now we need to get that ghost out of there.
  • I bit the bullet today and bought a replacement auto-dimming mirror for my 2000 Impala (@ $160 BTW). The replacement has a simple set screw to attach it to the mounting bracket on the windshield, but the original mirror is apparently held on by a different mechanism - it looks like there's a plastic cap on the end towards the front of the car, and then perhaps a metal clip that holds the mirror in place.

    Anybody have an idea as to how to get the old mirror off properly without damaging anything?
  • Well, I got home and tinkered with the mirror, and realized the rearview mirror on the 2000 Impala is held on with a black spring clip, so to remove it all you have to do it take a flat screwdriver and position it between the window and the clip and twist it to pop the mirror off (then I just had to unplug the wire clip for the map lights and auto-dimming function). There's a metal piece that remains attached to the windshield, which the new mirror simply slides onto (there's a hex key set screw you then tighten to keep the mirror on).

    On this model at least there's also a plastic piece that runs up to the headliner which hides the wires; this basically just clips on the mirror arm, and can just be pulled off the old one and snapped onto the new one.

    If I'd known it'd be this easy I'd have replaced this a couple of years ago!
  • This week had my 2000 Impala LS in at a Pontiac dealer for an oil change and inspection. Said I needed right side wheel bearings costing $500+.

    I took to a Chevrolet dealer I have dealt with and they said problem is just starting. They showed me that there is a slight give to the right wheel. Said fix could wait.
    I opted to wait to have repaired. Is this a safety issue?
  • How many miles do you have on your 2000, and any other symptoms (noise/vibration/etc)?

    Safety-wise I think the ride would get so bad you'd get it fixed before it got to the point of being dangerous (then again, I'm no expert).

    I looked in my Haynes manual, and as best I can tell this repair would require removing the driveaxles, and either replacing the bearings, or maybe putting in completely new/rebuilt units (which might be cheaper if they're available; they might cost more for the part, but labor costs could be less). It does look pretty labor intensive. I've replaced bearings on farm equipment and RWD vehicles before, but FWD makes this much more complicated. I've replaced my own brake pads, and will probably put on new rotors myself soon; but I wouldn't tackle this unless the car was a secondary vehicle that could sit idle for a couple of weekends.
  • Thanks for the reply. I have 70,000 miles on the 2000. There is currently no vibration or other sounds. I did see the estimate and $400 of the $550 was for labor. We are putting on significant highway miles every week, so it is inevitable that I will have to have this fixed soon.
  • Maybe you can get your rotors turned/replaced and new brake pads put on while you're at it...they'll have to take those things off anyway to get to the bearings, so maybe you could recoup some of the expense by doing it all at once and avoiding paying the labor twice?!??!?
  • My wheel bearings on drivers side front wheel started to squeak occasionally at 112,000 miles (2000Impala). If you are lucky you can find one used on ebay for $150, then it just becomes a problem of doing the labor, which you might wanna get a service shop to do. They might tell you to replace both at the same time with factory new bearings, but if the car is older and has over 100k miles you would probably be ok with the used bearings. good luck!
  • My 2003 LS Sport Impala just did something unexpected and looking for any insight into this.While taking a hard turn I noticed the "Low Brake Fluid" light flash on. I went to the nearest gas station and bought a bottle of Dot3 Brake fluid, while pouring it in to the resevoir I noticed that once it was above the Max Fill line it would seem to leak out of the reservoir. Is this a feature to prevent overfill or a cracked/broken resevoir? Thanks!
  • I read a post of yours about your grandfathers 2001 impala. My car is shutting down just like theirs did. My car is also 2001 impala. I was wondering if the fuel pump relay fixed the problem. The chevrolet place is unable to figure the problem out because it does not do this all the time. I read somewhere on this board that it could be a security problem. I would like to give some suggestions to the Chevrolet Dealer when I take it in.
  • If any body is looking for some good reasons not to buy the new 2006 Impala SS check out the postings under the Impala real world mileage discussions! Poor mileage, not so great performance, down right bad fit and finish. Maybe they can get it right in '07 - with the pending EPA reform's help.
  • I'm a UK based writer, working on a novel set in 1965 which features one of the characters driving a 1964 Impala sedan (5.4 liter V8). I need to know whether the ignition and trunk were operated by separate keys or by a single key (or was the trunk operated by a remote lever?).
    Any help much appreciated - thanks.

    GM did not implement one key for both ignition and door/trunk in old models (prior to 199x MY). So it is probably that the 64 Impala has two keys.

    I am going nuts opvetr this stupid Passlock. I had my 2000 GMC Yukon Denali and it worked fine for about 25000 miles, then one day the dreaded passlock system wouldn't allow my car to start. At the time it was under warrenty so I took it in, dealer said, "nothing is wrong". They ran tests and it came up normal. Sure enough , a few weeks later same problem. Now that it is not under warrenty, the passlock acted up at the dealer and they charged me $400+ to replace. Sure enough, exactly one week after I got back from dealer, same problem. This thing is ridiculous. i had my 8 month iold daughter in the car one tiime when it didnt start and we sat in the car for 70 minutes before it start in 12 degree weather. GM has to recall this piece of @#$%! Very Frustrated!

    Hey all.

    I own a 2001 Impala LS, I was wondering where I might find a site that contains modifications for my year of Impala (i.e. higher powered lights, neon glow, etc).

    Thankyou.

    Johndenton-

    I'm dating myself here... A Chevy Impala of that era had two keys. One (with a rectangular head) operated the ignition. Another with an oval head opened the doors and trunk. I do not believe a remote trunk release was available in that car.

    As an aside, the engine displacement would be referred to (in the US anyway) in cubic inches. I don't know offhand what 5.4 l works out to in cubic inches but I believe the V8 most commonly found in that car was a 327. I give you credit for doing some research on getting "car stuff" right. I've been reading a book by a great crime story author, tells a great story, great characters. But he keeps referring to cop's "Ford LTD's". They haven't used or made those in what, 15 years? But I digress...

    try a site call impalahq dot com. It's got great info on how to get around the inner workings of the car and take things apart without buying the manuals. Good luck!

    Interesting that you mention this. Several months ago I was seriously considering buying one of these cars new, but then the dealer told me about the Displacement-on-demand engine control system, which could not be deactivated by the driver. That was enough to convince me not to buy it. Almost without exception, when GM develops a new system like this, they will have problems with it the first year. Remember the 1981 Cadillac 8-6-4 fiasco?

    Also, any front wheel drive car with a 300+ HP engine has limited appeal.

    Can someone help or had this problem. I have 2000 Impala when turning on signal light it makes buzzing noise and sometimes turns the car off. This is really crazy.

    Have not seen the hole myself yet, but the dealer says that there is a hole in the intake manifold on my 2003 Impala (70k miles).

    Does not appear to have the leaking gasket problem - don't think that the coolant has gone down.

    I was driving it from Minnesota to Colorado and noticed that the power degrated much more at altitude than I expected. Then while stepping into it a bit more (not flooring it)to gain a little speed as I was dropping back going up a pass on I-70, the trans downshifted and the engine made a noise. The Check engine light was blinking (engine misfire as indicated in the manual). Car seemed to run just as well after this event - though still very doggy. Drove all the way back to Minnesota without much problem until the last couple of hundred miles. At that point, the car would barely run at idle. This would be expected with a hole in the intake. I don't know why it did not run like this right after the misfire.

    I assume a backfire formed the hole. Dealer says the hole is a "melted" hole. Why would it backfire? Something else wrong?

    Any ideas? Gtting the intake manifold fixed right now.

    I don't if they went to this composite intake manifold to save weight or money (or both), but it annoys me that they took what WAS a "bullet-proof" engine with the 3800, and then make this change which has led to numerous problems. I specifically bought my 2000 Impala BECAUSE it had the 3800 engine; of the problems I've had with the car (clunky intermediate steering shaft, warped rotors, etc.) I can dismiss them all except the upper intake manifold problem - this is the only regret/misgiving I've had about purchasing the car. Still love it, and mine was fixed under recall, but still one of those things that will nag me.
  • mfx007mfx007 Posts: 5
    I saw something that showed that the plastic intake saved substantially on cost and even more on weight.

    Plastic should never be used as a substantial engine part. I don't care how well it is supposedly designed. Looks like the series III 3800 went back to AL.

    The dealer changed the intake manifold and then noticed the cat was clogged. Fortunately the cat is covered to 80K miles and I have 70K. I never had a cat clog and I put tons on miles on all kinds of old heaps. Now I wonder what caused the cat to clog. If there is a hole in the intake, it will make the car run rich and ruin the cat. They speculated that a clogged cat could help put a hole in the intake. In that case the cat is clogging for some other reason. Maybe a leaky injector dumping fuel or I have seen reference to a poor fuel pressure regulator (for 90's vintage vehicles). I will have to keep an eye on the Fuel Consumption. If it is poor, then I know I still have a problem that may cause the cat to plug.

    My rotors also warped. At least I got them replaced under warrantee at about 35K. They are not warped now, but the dealer says that need a brake job at 70K. I think that I have just started to notice the intermediate shaft clunk. That is a pain.

    Maybe if GM spent less money on marketing and more money on development and agressive resolution of known field problems, they would not be in such bad shape. Coach K and Tiger Woods don't need the money that bad.

    Impalas are quite reliable but have a few more problems. My father-in-law has a 2000, and had a 2003 (wrecked - total). I have a 2002 with the 3.8 liter engine. The 2000 had the steering link problem as did mine. The 2000 recently developed the common manifold coolant leak (98K) and appears to working on transmission issues. This is not surprising as regular maintenance (other than oil and tires) is not a priority.

    In addition to the steering link, my 2002 with the 3.8 doesn't sound right when it cranks. The dealer looked at it three times and have extended the warranty on that item only. It always starts but hesitates on restarts when the engine is warm. Finally, it just developed the front-end rattle that I can feel through the steering wheel. That why I am checking the forum. It only has 42K.

    I would hope for better as I am used to doing only regular maintenance up to 100K. Good luck.

    For what it's worth, the 3800 warm-starting issue is pretty common. I owned an '02 Monte Carlo and my sister owned an '02 Grand Prix...both with the 3800. Both of our cars had the exact same "problem." It was annoying but knowing it was normal eased my concern. I also had the intermediate steering shaft problem. I was reassured by the service dept that it was not a safety issue. That made me feel a little better but it would be nice if GM would fix the problems even if they aren't critical.

    I have the failed intake part.

    I can see that the hole was the result of hot gasses from the EGR that "torched" a hole in the wall.

    This site shows a picture of the EGR tube that comes out of the lower intake manifold that sticks into the plastic plenum. My Plenum have a "torched" hole opposite the tube.
    http://ken-co.com/manifold/default.htm

    Seems the usuualy problem is general heating in the EGR area and there must be some coolant passages in the area that leak when the plenum degrades.

    The dealer that fixed it and a few other dealers that I called did nto have a good idea as to what caused it and they have not seen it before.

    They did say that it is plausible that a clogged catalytic converter could cause excessive exhaust to be routed back through the EGR.

    Dealer indicated "internal defect" for cat, so hopefully the insides were busted up as the failure as opposed to fouled up from a poor running engine. In that case, with a new cat the problem shouldmmnot happen again.

    We have a 2000 with only 49,000 we bought it new. In the past month if you put the air on it has a bad smell I am not sure what it smells like. But it is bad enough you will turn the air off. It does not matter if it is on recycle or not same smell. If you have the heat on there is no smell ?

    Thanks for your help .

    If your Impala is an LS it should have come with a cabin air filter, which is accessed under the hood. I think the manual suggests changing this annually, so if you've never done so, it could be the source of your problem.

    I have a 2000 Impala that I bought new; now has 114,000 miles on it; for the last year have been experiencing a frustrating problem with Security light--it will flash on and then go off; and shortly thereafter but never on a frequent basis, the car will not crank. It may be the same day or it may be weeks later; and then it may not do it for several months. I can sit and turn the key for several minutes and finally it will start. Just concerned I will be out somewhere and can't get it to crank and be stranded. Anyone else experienced this and what did you have to do to get corrected?
  • Just a thought.....My z/28 acts like that sometimes. a member from a camaro board said it was the "DATS" . I dunno man , take it from there. it may be something totally different.
  • Correction.....

    thats "vats" not "dats"

    sorry-
