    Just may be the way to go.
  • My wife had the same problem with a '95 Geo Prizm. It was the starter motor.

    I have a 2001 Impala. About a week ago the day time running lights were not working. As I was confused about this I pulled on the headlight switch in the car and I had no headlights at all. The parking lights work and also the bright lights work, but nothing else. My husband has been a mechanic for 20 years and he has been working on this problem all week. He change the BCM ( I think that is the name of the computer) and the pull switch on the inside of the car and still no lights.

    Has any one else had a similar problem? What can we do to fix this problem!!!

    On my 2002 LS at around 16000 miles dealer replaced instrument cluster due to noisy tachometer and did the lube fix to the ISS. When I got the car back there was a rattle on left side of dash that only occurs at certain temperatures (30-50 F)and can be cured by giving a good rap to the bottom of dash on left side. Could this be due to something done wrong on the ISS fix or the instrument cluster replacement?

    Now at 33000 miles and just weeks left on warranty the tach noise is back, I still have the rattle at various times and I have a new problem: a squeak that seems to be coming from engine compartment on right side. The squeaking seems to go away after driving car a few miles but also doesn't occur at all if someone is sitting in passenger seat in front. Makes me think it may be suspension related. A bushing?

    Anyhow, I will be trying to get some resolution to these items at dealer in next couple of weeks but wanted to see if anyone in forum has any experience with any of these problems.

    Other than the various noises the car has been excellent in all other respects.

    I got my '04 Impala in December, base model. Really enjoying it.

    However, I found that whenever I go in or out (especially out) of a driveway, the front of the car will hit the pavement unless I go extremely slow. When it first happened, I thought it was because the tires needed air (which they did). This didn't happen in other Impalas I rented or test drove.

    After adding air, the problem lessened somewhat. However, it hasn't gone away completely. It's scary to have to go very slow backing out of the parking space of my doctor's office, onto a busy street. You need to go slow not to hit the car on the pavement, but the quick oncoming cars necessitate your needed to leave fast.

    I spoke to the mechanic I have seen for the last 13 years (fear of going to the dealer) and he told me that Impalas have a low profile. He said what I am hitting is the air deflector, and not to worry. He said to go slow, and try to exit/enter steeper driveways at an angle.

    Anyone else have this issue? Have you solved it? :confuse:

    Thanks so much for your help!

    I have a 2000 LS, I believe all Impalas are like this. You either have to take the air deflector off or learn to drive slow in and out of driveways. Think of the air deflector as a warning strip, it's just plastic and the noise tells you to slow down to prevent you from doing real damage to other areas above it. It's annoying, but it is really good for you. :)

    Just confirming post #1135, the air deflector like on most cars catches air and directs it to the bottom of the radiator for cooling.......the 2000 - 2004 Impala's is a bit low and it is not a concern, just an annoyance.......Chevy changed the design on the 2005 Impala deflector, it is a couple inches shorter and on more of an angle, less likely to scrape going in and out of winter driving when there is more then 4" on snow on the road it acts like a snow plow which really becomes annoying...
  • You're the only person on the internet who has even suggested a knowledge of how to top off the power steering fluid. I have been a "shade tree" mechanic for 30+ years and I CAN'T FIND THE RESERVOIR FOR POWER STEERING FLUID ON MY 2000 LS -- Boy does that make me feel stupid!! I have looked in every nook and cranny of the engine compartment and still can't find where to add PS fluid. CAN YOU GIVE ME ANY CLUES?? I have the original owner's manual and it says "passenger side near the rear of the engine compartment". If that's a clue, it's a lousy one. HELP!!
  • i am new to this, but, here goes. my 2001 impala ls has a problem no one can figure out. the "traction active" light comes on and i feel a "pressure" against my brake pedal. it happens when i am stopping from a slow speed or am taking off at a slow speed. the traction control and abs lights intermittently come on, and i am sure that i don't have tire slippage. there is also a sound that goes with it. it sounds like a motor running or a pump running. i hear this sound when i feel the pressure in my brake pedal. took to the dealer and they said i needed a speed sensor. replaced that one as well as the other side. still have the problem and it seems to be getting worse.

    Hi, I have a 2000 Chevy Impala, and have the exact same problem with water on the right floor when it rains. I went through the same procedure as you also. I had a windshield replaced by a glass dealer, and at some point after that, the leaks started. I took the car back to the glass dealer and he told me it was common for leaves and debris to plug up the water drains. He took off the fender well and the plastic cowl assembly that is between the hood and windshield. He assured me that it was now fixed. I took the car home and ran the garden hose on the roof and let the water flow down the windshield. Within a few seconds, water was running out onto the floor inside the car. I immediately called the glass guy and he told me he did everything he knew to do, and he would refund my money for the work he did. My question to you is, did you ever get anyone to figure out why the water was leaking into your car? Thanks

    The air deflector does not direct air to cool the bottom of the radiator, but rather it forms an area of lower air pressure behind it which is filled by air flowing through the radiator above, thus causing a higher volume of air to flow through the radiator resulting in more efficient cooling. This counteracts the area of higher air pressure which forms under the front bumper area which partially passes through the front wheels. Notice how the front wheels are dirty with brake dust from the air flow going from inside the wheel to the outside, while the back wheels are always cleaner because the air flow through them is from the outside of the wheel to the inside.
  • charts2charts2 Posts: 618
    That makes sense.....the 2005 Impala deflector is much shorter and on an angle, how does that afect the air pressure behind the rad? Its half the size of the previous definetly eliminates the scraping going over curbs anyway.

    Thanks for the info!

    The irony is that I had a choice between getting a 1SC (more options than 1SB) right away or having an '05 built. They don't make the Impala 1SC package anymore, it also has sedan sport pkg. I wanted the more options over the Onstar. Always pros and cons to every decision. I do love this car, though!

    Thanks for all the info. :shades:

    Hey all - new member. I have a 2000 Impala with about 96K miles - obviously, I drive a lot. I have just starting experiencing a hard idle with inevitable engine failure (random) and also a hard shift when the automatic goes into 2nd gear. I also sense, at times, there is engine failure which corrects itself at high speeds (interstate driving).

    I did find some TBS announcements online but wanted to learn more about specific parts and if someone had a fix. :sick: link title

    Greetings, all!

    I just purchased this car (used) with 13990 miles from the same dealer of my previous new car (2000 Malibu - 6 cyl base model) - recently totalled in a rear-ender.

    One thing that has surprised me is the ride quality which seems harsher than the Malibu - I feel every little bump in the road. Dealer says this is normal for this car and Pontiac GrandAm. It is the base model so the sport suspension should not apply. True?? Tires are the Uniroyal Tigers-Paw.

    Most postings I've read seem to comment positively on the smoothness of the ride. I'm not feeling vibrations in the steering (steering seems tight and positive), but in the entire car.

    No, I did not test drive the car. Was happy with the Malibu and felt this would be even better. Price was $11550. CarFax said OK. Car came off a one owner 3 year lease.

    Also, first thing dealer had to do was cut the rotors - brakes pulsated.

    Any suggestions, please?

    There was a recall on many Impalas related to a fuel regulator, which might be the cause of some of your stalling/hesitation issues...mine got a little hesitant to start about the time I got the recall notice, and once I got the recall repair performed, the problem went away.

    I also had some hard shifting problems maybe a year or so ago, and as I recall there was some type of module that had to be replaced in the transmittion which solved the problem (seems like that cost @ $500).
  • lostwrenchlostwrench Posts: 288
    I wouldn't be concerned. If there was no deflector there, I would be.

    My engine starts fine in the morning when it is cold. However, during the rest of the day, it konks out on the first attempt to start it but will then run on the second try. Anyone have this experience and what was the solution? (2001 base, 3.8 liter engine, 65,000 miles)

  • emonteemonte Posts: 4
    Thanks for the reply. I did have the fuel regulator replaced due to recall - and hoped that would solve the problem - but it hasn't. I have never had a start up problem. Each time the engine shuts off - I can restart the car instantly. (knock on wood)

    I'll check the transmittion module - thanks for the tip.
  • help please--when I purchased my 2001 Impala the cigarette lighter/charger/adapter--whatever its called--in the front did not work but since I am not a smoker and the charger in the back did work did not concern me overly. problem is now that charger in the back does not work either. my husband has looked at fuses and nothing is bad. not sure where else to look and sure do not want to take it to the dealer and pay some outrageous fee to have it be something small we could have done. thank you in advance for any suggestions you can give us.
  • I have a 2001 Impala. I have had the same problems, the ISS, the brakes, the Intake lead. I have had the tach problem but did not do anything, just noisy in the cold weather. What amazes me is that GM knows about these problems and they still manufacture these vehicles with the same parts. I am in the market for a new car, since my 16 year old started driving; so she'll have my 2001 Impala. I really like my Impala. But reading the forum, I my discouraged that after 4 years, the ISS shaft problems has not been addressed. I am sure it's the same for the break problem; undersized rotors. Doesn't it cost more for GM to fix these under warranty than to fix the problem at the assembly line? And what do they expect the consumer do? It really amazes me. And they cry when the sales are down and Honda and Toyota are gaining a bigger share of the market. Today, if you compare Honda Accord, and Toyota Camry with Impala, they are in the same price range. So, why would anyone buy a chevy with known problems when they can buy a Honda that will run forever. I do hope that GM and other US car makers will start producing quality cars before they close the doors on manufacturing US cars. It's sad that they don't care and expect the consumers to buy their cars since they are American made (or should I say North American made since Impala is made in Canada). Just venting my frustration.

    You should check the contacts for continuity and for power. If you have a multi-meter it should be easy. If not, see if you can pry the socket out of the holder and physically check the wires for proper connection. The constant pull/push into the socket can cause wear and tear on the contacts or breakeage. Replacement of the socket should be fairly straight forward if needed. Good luck :D

    About 3 months ago I started getting a Low Oil Level Warning from my 2000 Impala 3.4. Oil level is fine - no leaks anywhere and it doesn't appear to be burning oil. Usually the warning will continue (only at start up) until I change the oil then it goes away for about 2000 miles but comes back until next change. Suggestions?

  • charts2charts2 Posts: 618
    The ISS problem has been addressed......after several attempts during the past 3 years there is a new part that replaces the original. The brake rotors on the Impala are the same ones used on the Police major complaints from fact it beat out the Police Crown Victoria in brake testing for police vehicles......If you have a complaint about your Impala and the service manager has told you there is nothing he can do, and you believe you have a legitimate complaint, ask the service manager the name of the owner of the dealership.......then write a letter to the dealership owner explaining your problem....send a copy to the service manager as well.....if you get your car serviced at the dealership explain that also in your letter......if you have owned previous GM vehicles say that........If you stop at the point you are at now you have no further reason to complain......its up to you to take further action! Thats how things happen! If you check the box at the top right of this page that says search this discussion and type in noisey tach or brake problems check out all the posts copy them and send them in with your letter to the owner of the dealership, informing him that these issues are common.....Good Luck!

    I hope anyone out here can help me since the dealer seems to be stabing in the dark about my problem. Here it is: The blower and the overhead console info sometimes works and sometimes does not....sometime it comes on when I start the car and sometimes it comes on later while driving and sometimes it doesn't come on at far the have replace the blower control ( the panel that houses the buttons etc that control the air, heat they are talking about maybe it is the body control module (which according to all the msgs I have seen, has nothing to do with my problem). Does anyone out here have a clue what the problem may be? 2000o Impala 73000 miles.
  • denicedenice Posts: 2
    Don I just read your msg here and I have the same problem and the dealer can't seem to pinpoint it .....what was the outcome of your problem
  • brucevbrucev Posts: 1
    I recently had the Low Tire Pressure light come on on my 2002 Impala LS. After checking the tires I looked in the manual to see how to reset the light. I used fix number 1 which was turning the interior lights on and off 3 times. That was after trying to use the settings on the radio. I tried for 15 minutes to get the settings menu to come up by holding the Disp button for 5 seconds or longer with the radio off (as instructed by the owners manual). I never got anything to happen. Any ideas here? I'd really like to have that menu available, but I can't seem to access it.

    How do you check air pressure of the original spare tire? My new '04 car was purchased end of last November, but made about a year before I purchased it. The tires lost a lot of air pressure.

    I have a digital tire pressure guage, and am able to get the tire pressure of the four regular tires ok. To make a good seal for accurate reading, I hold the stem with one hand, and the guage with another. Takes some effort, but I can make it work.

    The spare, however, is another matter. The stem is hard to reach, and impossible to hold while checking the air pressure. It's under the metal "cover" of the middle of the tire.

    This is the second time I have tried to do check the spare's tire pressure. I think the tire pressure is 45psi, vs the 60psi that it should be. But I could have measured wrong. After trying this last time, I figured I'd give up because I'm afraid I could break the stem. :confuse:

    Anyone have ideas? My next idea is to take it to the dealer, but I'd hate to wait for hours for them to check the tire pressure of my spare. On the other hand, I'd also hate to get a flat and not have enough air in the tire.
  • charts2charts2 Posts: 618
    Most spares are probably low on air.....thats one thing that many tend to overlook and as you say is difficult to check..Most Oil/Lube centres including the GM dealerships offer a 20 or 30 point inspection of your car when you go in for an oil (oil change) appointment make it known that you would like your tire pressures checked including the spare in the trunk....tell them that you have had difficulty checking the spare and you are concerned that the pressure might be low on it.......if you can be present while they check it be there....if not ask them afterwords what the pressure was..........I am sure they will address your concerns......good luck!

    Check some of your local automotive stores for an Air Valve Extension. Someone use to make one. That may help.

    also, if youre refilling up your tire pressue make sure you reset you tire pressure monitoring system.
