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.   Good luck! Ron

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.

Replying to: norbnancy (Jan 01, 2008 5:17 pm) 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?

Replying to: thatism (Jan 08, 2008 6:01 pm) 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.

Replying to: quietpro (Jan 10, 2008 4:21 am) 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.

Replying to: norbnancy (Jan 12, 2008 7:26 am) 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. |
