2008 Chevrolet Impala

Do we have any other 2008 Impala owners here?

I just bought the car a couple of weeks ago, I traded an SUV in on the car. One of my expections was that the Impala would get better gas mileage. So far I haven't been disapointed, I've been getting between 26 and 27 mpg on my daily round trip commute of 75 miles.


  • I have a 2008 LTZ with all options except sun roof. The very best fuel mileage was 30.1 one time. The average over 4379 miles is 25.9573 mpg. Since winter has set in, it is somewhat less. When on the interstate I drive 65 to 70mph which seems to be the sweet spot.I have no issues with this car so far, very satisfied and an easy car to wash. Enjoy the ride.

    Does your compass work correctly? I set mine to the correct region number and it was still not correct. I have tried the calibration mode, the DIC tells you to drive in circles. I find this a little strange as I wouldn't think the compass would be that difficult to calibrate.

    I am reasonbly satisfied with the car to date, it certainly rides and handles much better than the SUV I traded in.

    Driving in circles to calibrate the compass is normal, in my experience. I can't speak to other makes but it has been a requirement in the cars I've owned.
    What exactly is your issue? Is the compass not working at all or just seem to giving erroneous headings as you drive? Be sure to calibrate it in an area with no interference...preferrably a place with no light poles or away from buildings.
    Mine works like a champ although I don't expect perfection. After all, it's only giving general heading not a specifice degree readout. Let us know how it works out for you. :)

  • axinutaxinut Posts: 11
    The directional readings were erroneous, It is now calibrated, driving around cloverleaf interstate interchanges must qualify as "driving in a circle', that is where it was finally calibrated.

    I do need to check the headings.
  • quietproquietpro Posts: 702
    Keep in mind that the calibration feature will eventually stop bugging you to calibrate and will eventually return to giving the general direction based on the calibration it could achieve through your routine driving. However, it wouldn't be fair to judge the system if you haven't taken the time to properly set it up. The recommended calibration only takes a minute or less (literally) and will then give you a much more accurate reading. The only real issue with doing it is that you make look a little silly driving in circles. The folks working in the establishment who's parking lot I used were looking at me funny through the windows. But, I just drove away afterwards so no harm done. :P :D

    Good luck!

    I bought a new vehicle about a month ago, and I'd set up the proper zone on the built-in compass, but had never taken the time to calibrate it properly. Yesterday afternoon we were driving through a neighborhood looking for houses for sale, and wound up on a cul-de-sac...PERFECT time to stop and calibrate the compass! Sure I made an extra loop around the circle, but now it's done.
  • quietproquietpro Posts: 702
    Cul-de-sacs are also a very good option as there will likely be less interference in a residential neighborhood. However, there is a higher chance of odd looks coming from the residents. :P ;)

    I had a hard time calibrating because of overhead wires. Finally found a field by my barn and it calibrated in short order. Seems accurate since. Have been on a long trip, 28-30 mpg, runs great. Enjoy the ride.
  • axinutaxinut Posts: 11
    I did get my compass calibrated. I set the correct zone first, then pressed the check to calibrate the compass. It took five or six circles in an empty parking lot, The directions appear to be correct.

    I am getting about 27 mpg for my 70 mile a day round trip commute which is mostly interstate highway driving through the city. Trafficwise some days are better that others. The worst mileage I have seen so far is about 23 mpg on stop and go in town driving. I am very happy with the gas mileage, this is one of the reasons I selected this particular car. I have the 3.5, 211 HP V-6 engine. :)
  • When I have the heat on there is an intermittent ticking noise that comes from somewhere in the dash. Anyone else have this issue?
  • quietproquietpro Posts: 702
    There was a TSB for the '06 model's dash ticking but it was due to dash clips rubbing against the windshield. I believe that problem was fixed in the mid-06 run. Does it continue indefinitely or seem to calm down after the car has warmed up?

    As for your '08 model, is it loud (like a rock hitting the windshield) or fairly minor? My guess is you're hearing the different components "creaking" against each other as the temperatures equalize. This is basically the same thing that was happening with the early '06s but the noise was louder due to metal rubbing against glass. I think it's just plastic on plastic in your case.
  • Thanks for your post.

    The ticking continues for as long as the heat and fan are on. If I switch the fan off the ticking stops. The ticking is not very loud but can become annoying (it can be heard over the radio) and is hard to locate but it comes from various locations in the dash.
  • norbnancynorbnancy Posts: 118
    When cold (20's, 30's,40's) I get a ticking noise in the dash area that is very minor. It sounds like plastic parts expanding, probably in or around the hearer ducts. I would not allow anyone the oportunity to tear into it in the hopes of finding the cause. The ticking is not bump sensitive, but heat change. If the ticking noise is related to only the blower motor, it would occur throughout the heat range.. Since I have traveled south, it has not re-occurred. At 8000+ miles my 08 LTZ continues to be a great ride. In town driving with some hyway is currently producing 25.8 MPG. Enjoy the ride.

    I used to have that in my 2000 Intrigue, it went away on it's own. Extreme cold and heat do things to a car's plastic after manufacture.

    I took a look at an 08 LTZ at the auto show. My big disappointment was rear seat room. The new Malibu was much better. Otherwise, it's on my shopping list.

    I have what I described to the service dept as a ticking in my dash, but the said they couldn't replicate it. It is not constant, but I will hear it days in a row even when the heat/air is turned off. It happens in hot and cold weather before and after the engine has heated up. The rythmn does not change. An independent ASE mechanic heard it and said it sounded like the blower fan, but another one said if it was the blower fan it would change rythmn with the speed of the fan.

    Hey folks. My sister has a 2007, couldn't find one on this post board. She had a horrible accident
    this weekend and the airbags failed to deploy. Do any of you know any history of Impala's having
    an airbag problem? Thx. Minnesota.
  • axinutaxinut Posts: 11
    I thought I would check back in, we are still doing well in the gas mileage department. I am getting 27-29 MPG on my 70 mile roundtrip commute every day and have even had a few days where the avg gas mileage was over 30 MPG.

    Everythings still running OK and haven't had any issues with the car yet. I'm still very happy with the car.

    Is everyone else out there having good experiences with the 2008?

    It's beeen a couple years since I bought my 2006 2LT and I was curious about the current model year prices, options, etc. When I went to the Chevy website to use their build option, I discovered a new model--the "LT 50th". Granted, it's just a trim difference from the 2LT, but it does offer one interesting feature as standard equipment: the FE3 Performance-Tuned Suspension. Does anyone have any information regarding what the differences are in spring rates, front/rear anti-roll bar diameters, etc? Limited options on the car--sun roof and side molding strips; two colors--black and Red Jewel Tintcoat. Standard equipment--leather interior, 18" wheels, ABS, Stabli-trac, special ID markings, etc. Anyone seen or driven one? Thanks, Clark
  • axinutaxinut Posts: 11
    I wasn't aware of this model, I'm sure I haven't seen one, but I will be on the lookout for 17.
  • beach15beach15 Posts: 1,305
    Yes, they're out and about.

    Basically, a 3.5L LT model dressed with special leather seats, badges, the SS suspension (that's what FE3 is) and larger wheels.

    Here's one:


    Previously, they were supposed to come with the wheels used on the LTZ, but these late '08 50th anniversary cars seem to have been built using SS wheels instead.
  • cnwcnw Posts: 105
    Thanks for the photos and the comments. Have you had a chance to drive it? How does the FE3 suspension compare? Does it tighten things up a bit?

    Thanks again,

    I am the operator of a brand new 2008 Impala LS (fleet owned car). I have experience with many makes of foreign and domestic autos, most recently Ford, Honda, and Mercedes.

    I have had this vehicle for a few days and 1100 miles, an would like to offer the following impressions:

    1) Fuel mileage - I'm observing the mid to upper twenties (computer provided figures, not mine), and the engine is arguably still not broken in. I expect this will rise. My observations include a spirited drive from Northern Ohio to Northern Michigan, and a dose of E85 thrown in.

    2) Fit and Finish - The General did a good job on this one. Everything is tight, consistent, and has a quality feel. There are no squeaks or rattles yet, though I fully expect a few new-car bugs.

    3) Design - Visibility is average. Control access and entry/egress are good. the trunk swallowed ALL of my professional equipment and there is still room left.

    4) Ride/Handling - Competent, if not above average. It is not a sports car, and it feels better on our lousy roads.

    5) Value - This vehicle is a teriffic value for the money. I look forward to a productive relationship and I will report back.

    Reporting in. Purchased new 7-30-07. all options except sun roof. Great car in all respects. Never returned for any work. I do my own maintainance. Gas mileage since new 25.88 mpg using regular unleaded over 13400 miles. The driving is a mix of hyway at 65 - 70 mph. and some short runs of 5- 8 miles. Ths short runs kills the mileage. I had a 2000 Impala LT with the 3800 engine which gave me 28.4 mpg over 41000 miles. I suspect the performance gearing results in less MPG. In any event, I am well satisfied. The mileage beats my 1972 Monte Carlo 350 CID, 3- speed stick which gives me 17.2 MPG. Enjoy the ride.
  • One of the main reasons I traded my 2003 Impala for a 2008 was the ability to utilize E85. My in-city mileage was 22.4 with regular gas but only 16.6 with E85. Thats more than a 30% drop in mileage. I am finding that my mileage cost is 18 cents per mile on E85 and 16 cents per mile on gas (for in city driving). E85 is now $3.19 in Atlanta. Only when the price of E85 is 30% less than gas will we break even. Since I have to fill up more often on E85 and it costs me more per mile I am going back to regular gas. I will wait until E85 is MORE than 30% LESS than gas.
  • quietproquietpro Posts: 702
    Thanks for the info on E85. I am curious if you are driving stop and go or is there more gridlock/idling. Is there any performance increase with E85? I haven't read as to whether the engines are tuned to take advantage of the higher octane. Regardless, the costs outweigh the benefit. I consider myself a "green" person but have not jumped on board with E85. If you look a little deeper, your expenses are higher still once you figure in farm subsidies and tax credits for the producers of ethanol. :cry:

    Happy motoring with regular unleaded. :)

    I have a similar problem with my compass. I live in the middle of zone 3 and 4 and so i calibrated for zone 4. I recently drove 100 miles south so i am definitely in zone 4 at this point and my compass worked perfectly.

    I am haven't tried to set it to zone 3 yet, but will report back... do you think that you are in a weird calibration zone?
  • rwesselsrwessels Posts: 2
    I hear this sound in the engine compartment from time to time. The dealer has put over 160 miles on it and 'cannot replicate' it. So I made a recording and they still say that they cannot do anything about it till it happens.

    The sound can be downloaded clicking here (and is annoyingly loud).

    Has anyone else noticed a high pitched whine happening occasionally with a pitch that varies with RPM?
  • axinutaxinut Posts: 11
    No, I don't think so, I was able to set mine by following the instructions in the owner's manual, it worked like a charm. If you can find an empty parking lot or cul de sac it will make the job much easier. Five or six circles should do the job.
  • sylviaesylviae Posts: 31
    Please tell me---which size tires/wheels would be the best on a 2008 Chev Impala for the best ride or driving and handling. I was supposed to have 17 inch wheels on it but they put factory 16 inch instead---I am not happy with the dealership not honoring my request in buying this new auto---is there any difference in the ride with the 17 inch wheels and will it give me a better ride???? Please give me some advice. I also requested a 6 CD Changer and got one called an aftermarket---a Pioneer in the trunk and it has to be tuned to an FM signal. Is this the best I can do?????
