On order: Torch Red Z51
Was driving me batty until I figured it out. I had remounted my Escort just over the security light front center of dash. In the process the slide on the mount that goes into the detector had caused a slight separation in the seam between the top and bottom of the unit and (on an extreme goose of the throttle) I can cause it to eject back into the cabin 
. Gotta get it fixed, probably with super glue & a vice. Anyway that's the buzzzzzzzzzzzzz resonating in mine. Vin#3206 and just turned 8700 as I was returning from the Bash.

It is noticeable when normal acceleration occurs at about the 35-38 mph range, and again when normal deceleration from about 57 mph to 50 mph or so. It appears that the harmonics are just right during these two episodes to cause a very noticeable rattle/vibration.
From experience, these kinds of rattles are hard to pin down, especially if within the dash.
Anyone else experiencing this or similar?

What a stupid comment. Oviously you have never had to do real work like work on an assembley line where GM gives you a minute and a half of work to do in a minute. That lazy line worker puts that panel on the car either using a jig to place it correctly or a robot most likely put most of the panels on it. In my plant ALL Most all panels were welded on by a robots and the doors hood and trunk were installed using a jig that the lazy line worker had no control over. The people who did were mostly people who never did a honest days work in their life and just complained about those who did.

And when a bolt goes in crooked and strips and doesn't sit flush, there's no mechanism to correct it? There are a LOT of different issues in here than just stupid panel placement and a LOT of them could have been avoided or corrected. I don't care how much time I have to do something, if it's not done right, it needs fixed. If you don't care about these things, why are you even bothering with this thread? Simply to defend shotty work because it hits home to you?

Oil Splatter - PCV System
Took mine into dealer for oil leak. Told me it was coming from the PCV system. Oil was in the airbox and all over the front crossmember. Dealer said this is the second one they've seen and it is discussed in Tech Bulletin PIP5165A which I have not seen. My car has 1800 miles and the leak started just a few days ago. Anyone know where I can get a copy of this bulletin or have seen this issue before?

As per a knowledgeable tour guide during a an October 27th VIP plant tour ... replacing a C7 windshield, front or back, is no easy task ... Both windows are glued in with an epoxy type glue that is very different than the sticky- rubber type windshield glue we have known in the past making the R&R considerably more difficult. Should be of no concern for a new owner in this situation except that an outside installer, (most dealers use outside installers), may be attempting something for the first time. First time attempts sometimes lead to screw-ups, so check their work carefully.

Case separation on Escort radar dectector

I purchased a new Escort Max radar detector for my c7. After about two months the case started separating. Called Escort and they acknowledged they were having this problem on the early models. I was instructed to send it to them at no charge and they would replace the case and install latest updates. It took about a week and a half. Hope this helps!

If the oil change is not done correctly, you can get an oil leak from the TB area due to the high oil level. If your leak occurred before the dealer changed the oil, then probably not. If would have been good to check the oil level on your car right after you got it to insure the level is accurate. I plan on doing that to get a reference point of the correct level on the dip stick. Another poster noted the same issue and found 2 plugged PCV valves.

The early Z51's had to much oil in them, that oil was being pushed into the throttle body on wide open throttles. That's where your oil leak came from. The manual said 10.3 quarts on early Z51's and now it's been revised to under 10 quarts, I think it's 9.5 quarts.

Take particular notice if you hear the rattle when the car is idling on your driveway.(Note: with the trans in the rear, the driveshaft is turning even though the car is in neutral/park). If you hear it then, it could well be the front driveshaft bearing that went out of my C7 2 times. I've posted on this forum that I have had my entire driveshaft/torque tube assembly replaced twice within the first 2500 miles and the problem (ie rattle) has finally gone away. My C7 is #1134.

Something minor, but noticed that when you have an apple device connected via USB, the songs don't display on the dash screen when songs are played from a playlist (dash screen obviously set to audio). They do display on the central screen including album covers. Always displays on both when selecting the song via album, artist, etc. Also, when playing from a USB drive, playlist songs display on both screens. Not sure if we should even post minor things like this..... SJ

i asked the dealer if there were any updates. he said no.
since there are no egregious problems, i have let it rest for now.

sounds like problem solved. i played around with the back up mirror adjustment and it is working as it should for now. maybe it just needed a software massage. ??

Has anyone get their driver's seat memory working correctly yet? I mean when entering the driver side and closing the door the driver's setting happens? Like moving forward and the steering wheel moves to your settings? Gm contacted me asnd acted like they did not know anything about it.
