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.

    axi,
    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. :)

    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.

    axi,
    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.

    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.

    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.

    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

    I wasn't aware of this model, I'm sure I haven't seen one, but I will be on the lookout for 17.

    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.
