Chevrolet Impala: Problems & Solutions



  • it's a bushing in your steering joint. has an explanation and even a fix listed for it. you should check it out. i have the same problem on mine, which has been wrecked before. i haven't fixed it because i don't think it's a mechanical problem as much as it is annoying.
  • I really like this car, but it's been giving me one headache after another since April - most recently, the car seems to have trouble changing gears...when I accelerate, it's very sluggish and then seems to "lurch" into gear - once it did this as soon as I took my foot off the brake; other times, I'll be driving along and the car will lurch slightly even when I'm not accelerating. The problem is intermittent; days will go by and nothing happens...this morning, it did it again. This just started about a month ago. Before I take it in, I'd like to have some idea of what's causing this if possible. Anyone else had/have this problem or have any idea of what it could be? I sure would appreciate some input!"> :confuse:

    I had a similar problem maybe 2 years ago on my 2000 Impala..seems like they replaced a pressure control module or something on the transmission. I don't remember exactly what it was (or what it cost), but I've had no shifting problems since. I do have some occasional transmission noise (a whine, especially at low speeds), but that's about it.
  • I have been having same Check Engine light error message for some time. I I had fuel injection system clean done by my shop since this error came up. If so, that didn't help, but I'll certainly try your suggestion before biting the bullet and replacing the valve...I was also quoted ~$200 for the part but did find it online @ AutoZone for ~$150. Anyways, where can I get that SynFuel you are talking about? I Googled it and it didn't really come up with any hits. Is it easily found at AutoZone or other auto store? Also, do you think the Premium gas helped when you tried it? Just never use anything but regular in my car (2001 Impala). To confound the problem, my fuel gauge has been on the fritz for some time as well (since my wife ran out of gas ~15months ago) and gives a voltage error reading on the computer. Thanks!
  • to reset the low tire pressure light you have to have the car running and turn on the parking lights 3 times consecutively in ~3-5sec (pull/push the light fob)
  • Did you get an answer for this? I live in Louisiana and it is always humid but I never equated that with my blinker problem. Sometimes, my blinker doesn't work. I stop my car, turn off the engine, and turn it back on. Works fine after that. Someone told me it could be a multiplexer (?). I REEEAAALLY need to do this myself to keep cost down. Any ideas??

    I have a 2004 Chevy Impala that leaks water on the passenger floor after it rains. The Impala has approx. 18000 miles. I plan to call a GM dealer this week. The water shows up on the passenger vinyl trim by the passenger door and water on the carpet. I would like to get this fixed before the end of the warranty. Also the car had a thumping sound in the front passenger side - this noise went away finally. Now there is an intermittent rattle in the passenger side dash.

    A few weeks age i bought a 05 Impala and i had to install a 2 way radio into the car for work. Since i did this my A.C. will not work. I unplugged the radio and tried it and it still won't work. The yellow light turns on when i push the button and nothing works. I hooked a volt meter to the different relays and fuses and everything has power (and yes the fuses are ok they didn't pop) So i hooked the volt meter to the compressor itself and there is no power to it. Did i ground out something and fry the BCM to the AC or the control head? Any suggestions short of going to chevy and paying out the nose to get it fixed? Thanks all and yes i know im a moron. Again thanks in advance for your replies!
  • Just had this problem this weekend. Whole passenger side floor was flooded into the back and over to the driver side as well.

    I have a 2002 Impala that will not start. No blown fuses, battery OK.
    auto door locks and trunk release won't work. When you turn key in ignition engine will not turn over . No power to radio and courtesy lights will not burn. Prior to this problem Security light would come on periodically, but never created problem. Low tire pressure warning did come on and was reset prior to this problem. Any help out there!!
    Thanks, Hugh

    Did anybody ever find a solution to these water problems posted several times here? I get water on passenger floor and right rear floor when it rains. Any help greatly appreciated!
  • I had a similar problem that left me with 3 inches of water on the passenger side floor,the exact phrase at my gm dealer was hvac intake seal,located near cabin filter plastic cover (the cover on the outside near wipers) apparently in my case the wiper tore the seal off after winter freeze, if it is this water will leak from the light bulb under the glove box it will look as if the bulb is leaking, the water comes through the fan assembly. there solotion was double sided tape to replace the old seal on the plastic shroud below the wipers.
  • Apparently our BCM body control module is on the fritz, at l;east that's what I've gathered from my edmunds research. It is about 184.00 to buy the part and 50 or so for labor. I am in the process of seeing if it can be down by a friend or if it must be done by a pro.

    Here is the follow-up. The fuel injection cleaner fix was short lived. After that the warning light remained until I had the EGR replaced. SynFuel is made by Valvoline and seems to be equivalent to Techroline made by Chevron. My fuel gauge is also dead. Has been for some time. This is a very common problem looking at this forum. The impalahq site has a "how-to" on replacing the sensor. I haven't had the time or the faith in my ability yet to do it myself. Maybe when the weather cools off. I just use my trip meter to know when to fill up.

    If you decide to change out the sensor let me know. I have the sensor you would need, at one time I had the same problem you had with the fuel gauge. I had purchase one and was ready to change it out when I decided to put in a bottle of injection cleaner. It fixed the problem, no need to change out the sensor. By the way, I also live in Houston getting it to you would not be a problem and I could possibly help you put it in. :)

    I just bought a used 2004 Chevrolet Impala with 41,000 miles and noticed that the factory stereo system gets very hot, but that really is not the major problem, The major problem is the speedometer, when I am stopped it will stay at 50mph and then when I begin to accelerate it starts increasing from that position. Any advise?
  • I have a 2000 Impala. When ever the heater or AC is on it is leaking water. The water is leaking on the floor of the passenager side from the dash. :cry: We have no idea what is wrong. We would like to fix it ourselves if possible.
  • Hello I have a 2000 Impala. I have changed the fuel pump and filiter. I can turn the key at times it crank up fine. I can be driving at about 70 and the car will shut off as if there is no fuel. I had it put on the computer and it didn't show whats was wrong. If anyone has had that same problem please advise.
