Could they have overfilled the resevoir and would this be normal behaviour?
Thanks!
Of course, if the coolant is leaking out around the intake manifold, that's another story!!
I just had the front wheel hubs replaced and wonder if there is some interaction going on with the BCM.
Oh and just fyi - original rotors (some vibration but not bad) :shades and pads, no tranny problems and 26-29mpg. :P
The fuel gage problem sounds like the float is gone bad.
Seriouslly. I would take that car back, get your refund and take your business somewhere else. let your friends know not to go their too. The car doesnt have any "chilld" safety feature like that. If you search these and other forums you will find simiilar issues,but with various solutions. Someone probably was trying to add something to the electrical an could have did some creative wiring or there could be some other issues. Fof the $$$ you spend even on a used car, i wouldnt take any crap from a dealer and i wounldnt put up with any car with issues right off the bat.
Get your money back and do some research on used cars before you buy one. There are numerous books on used cars and known issues/recalls. It doesnt mean your going to have all of those problems, but it will give yoiu an idea on what to expect.
Try a code reader to see if any sensors are inoperative. (Autozone will do it for free if you have one in your area)
As far as the transmission, you can probably change the tranny fluid and filter, it is probably due if it was'nt done before. If that doesn't help you may have to go to a tranny shop or dealer to diagnose and fix problem.
I browsed through some TSB's but didn't see anything relating to my problem.
Thanks in advance for ANY information that ANYONE can give me. I'm at a complete los as to what I should do.
My garage checked out the thermostat, water pump and searched for leaks. When they took a thermostat gun to the radiator, they found it to be clogged. I replaced the radiator and its all better, for now....
The details of how I fixed the problem are found on

ImpalaHQ is a personal website from a gentleman named Nathan who owns an Impala LS. He started the site so Impala owners could have a place to share ideas. I have found it very helpful.
Basically, there are little metal fingers that press up against little metal contacts as the float goes up and down. For my car, the fingers actually wore off and I had to replace the fuel sender switch assembly. The part cost about $90 (I think, anyway). If you had to replace the whole sending unit, it would cost closer to $300.
The labor involved for a first timer was probably two hours - that includes me figuring out where to start and how to get to the sending unit (there is a little access door in the truck under the carpet - just rear of the back seat).
I hope that helps,
Jim
The blower motor and resistor are both at the toes of your front seat passenger. If you go up under the dash on the passenger side, there is a insulator panel that you have to remove (I think all you have to do is press on a couple of clips and then the panel should be able to just be pulled out) and then you will see the blower motor. Forward of that (toward the firewall) you will see a big connector (which plugs into the resistor), disconnect that and then you have to remove the three small fasteners that hold the resistor in place. I hope you are limber because getting those little fasteners out requires you to bend your back in directions that you didn't know it would bend.
(If you can, only remove the rear fastener and LOOSEN the forward two. Those two are very tricky to get to with the carpet mat squished up there. The forward two holes in the resistor are actually slots, so once the rear one is removed and the front two have been loosened, you will probably be able to slide the resistor rearward to get it out from under the front fasteners and then pull the resistor straight down. - This could save your back a bit)
Once out, buy A BRAND NEW REPLACEMENT resistor from the dealer - or you could buy one first, but don't buy used or try to fix it. Upon examination of the resistor, you will immediately see the problem - some of the soldiered circuits (the two thinnest ones in your case) will be broken. I tried to soldier a wire in place and then re-seal the circuit board. That lasted for several months, but ultimately had to be replace as it broke again.
GM (or Chevy) has redesigned the resistor to include actual resistors. I lost the low speed in my Impala and Monte Carlo. Both have now been replaced with the new, redesigned resistor and I have had no problems.
I hope this helps,
Jim
Thank You
I am also looking for resolution to this issue.
2nd issue is a whirring sound in the engine - followed by a hard "shifting" from 1st -2nd (even though it's an automatic). Any suggestions?? :mad:
Full tune up has been done. Problems still exist - getting worse. I found TSB's that seemed related - but of course no resolution for the TSB. Code reader had returned 2 different codes at two different reads.
I am now also experiencing the gas guage problems listed throughout the site. Interesting to have a full tank of gas after a trip from Va. Beach to DC.
Thanks for the info - but I think I am stuck taking her in for a check.
Rochester, NY
Can't hear the noise when running in a steady speed even on highways.
Took it to a couple of mechanics. One said it's normal. The other cleaned up the throttle body, but the noise is still there, the gas mileage got no improvement. Both told me there is no vaccum leak.
Any advice is appreciated.
Please Help!
how's the fix? has to be replaced?
Mine has only 40K miles on it. A friend of mine says a clogged cat converter on low miles could indicate something else is not working well, especially engine.
Sometimes my turn signal does not work at all. One time it may be working and then the next time I use it, nothing.
My fuel gauge is also acting up. It goes up and down. I put in gas yesterday and it did not move. This was the first time this had happened. Now it is bouncing back and forth between empty and half tank.
Could these problems be related?
The vent selector works on pneumatics to open and close the various vents. Mine went bad in some way. If you turn off the fan and the radio and listen carefully while changing the selector, you should hear the pneumatics making a little swishing sound and the vents popping open and closed. I believe my mom's malibu had a similar problem that was fixed with the switch being replaced.
As for your other problems, I can't help.
Look up the instructions on removing the instrument panel trim (takes about 30 minutes to do the first time, till you realize nothing really breaks when you remove it). The instructions are on the internet at a website that sounds like impala hq dot com.
Just replace the hazard signal , it controls the blinkers and fixed the same problem for me in my impala and my girlfreind in her Malibu. They even had a recall for the same part in the malibu to address your issue in the Impala.
