Did your dealer mention anything about availability of nav/radios, rear cameras, and 20" wheels? Mine doesn't have any info when any of these will be available.

He did state that there was a problem with availability of the NAV radio; however he stated that it was a very short term issue. He did not mention 20 in wheels or rear camera.

Thanks, I agree with your BLUNTNESS, however that was not my question. I asked if anyone had any real world MPG data and what octane THEY were using.

I have 2007 Tahoe LT2 4X4, City 15, Mixed 17 and 19 Highway. I run on 87 octane, no idle or pinging problems. I have 3,300 miles, so far. I just had a problem with an EBCM module which shorted out causing my stabilitrack to be disabled automatically. I have had 4 fit and finish and a radio problem on a non-nav radio. All items have been repaired/replaced by dealer except the radio problem which is waiting on a fix from GM. Since I purchased my Tahoe on 1-25-06, it has been in the shop a total of 6 days. Three of those days were idle days waiting for a EBCM to come from the factory because there are no parts in the system. I still love my Tahoe, it is a top notch vehicle and I attribute most of my problems to being the first year/first run. Would I buy the same suv knowing what I know now? OH YEAH! Hope that helps you.

Go back to Post #657 & 658 .. that might help everyone to install their Fascia cover. .. I had no troble installing it when I taped the bracket to the bumper instead of using the template .. Note: that cutout on the bracket also lines up with cutout on the plastic bumper.
...
My cover has been on the Tahoe for about two months .. and I have had no trouble with it and the fit to the bumper is snug & tight!

OK, thanks for the reply. Thing is, I didnt install mine, the dealer did. Seems odd that several others have the same issues. I'm not sure how I would fix it and I'm not sure the dealer is qualified to fix it since they couldn't install it correctly and said it was.
The logical solution is to move the bracket closer to the bumper edge so the top tabs can engage the rear key slots. Means more holes

A Possible FIX -- Position the bracket at the correct location on the bumper and holding it temporary with 'Duct tape' ... then redrill the holes for the plastic push pins in the correct locations ... or if the NEW holes are to close to the OLD holes (and/or) won't hold the bracket securely with the push pins .... I would try using a few 3/16 inch 'pop rivets' where you have clearance. (I did and it worked great) .. Keep in mind .. the bracket should normally never have to come off the bumper and it's more secure that way!

I installed the rear facia myself and when I went to put it on, the left bracket would not engage and was bending when I pushed it over.
I thought I had installed it wrong. But I kept messing around with it and if when pushing it over to the left to engage the tabs, you pull the bottom back towards you, it will put the tabs at just the right angle to clip in and engage snuggly against bumper.
Try that, it worked for me.

I have been driving my LTZ 4x4 for 2 weeks now and the mileage is getting worse! I have been really light with the foot too. I was getting 14mpg but now i am down to 12mpg.
I read somewhere that GM has stated that the trucks transmission needs a final calibration. Anybody got any takes on this?

I do not know of any transmission calibration, however both the computer and odometer need to be calibrated to the tire diameter, and final gearing. Are you running 373's or 410's in the rear-end ? Have you changed tire or wheel size? Are you sure the truck is shifting out of the 4X4 mode, running in the automatic setting will reduce MPG also.
