If you read other Scion sites and earlier posts on this one, there are many many tC owners facing the moonroof noise problem. If you have this popping noise when the moonroof is shut call Scion so you can get a case number and they can find a fix to send to dealers. Mine has been at the dealer for a week while they claim that they are unable to get an answer from Toyota.

a week is outrageously ridiculous to have someones car. Go get your vehicle back and find another dealer. The fix is already out for the noise, stop getting dicked around. -t

There are many rumored fixes - I have yet to hear of or see the official Toyota or Scion version. If you know where it is...

just chatted with scion.com (chat program).. and they said "it is still being researched".. no TSB has been issued yet.. how difficult can it be to find this? when many are reporting that it's re-torquing of the front bolts on the sunroof? any thoughts?

Is this the pop noise I hear when slowly walk the car up a steep driveway?
Yes that would be the noise. Mine does it when I back out of my driveway.

so the headliner is going to be replaced? or the structure that holds the sunroof and makes it open and close?

also what vin # is yours? manual or auto? thanks.. with all this info we're getting as a community i think we'll be able to track it all down.. almost faster than scion..

I responded to ur question in the other thread that I started on this subject...I also wanted to add though that they did tighten some bolts at first and that did minimize the the frequency of the sound...but it didnt do the trick.

I was told by the dealer today that there are both "front" and "back" moonroof noises. The part for the back noise (which I could not distinguish as coming from a different location) will not be available until September but the front noise has been fixed after they did something to the headliner. I'll believe it when I don't hear it tomorrow after I pick my car up. My vin# was in the 4000's. Keep calling them so they fix this action...

thanks i got your other message.. and yeah now that others are experiencing this.. we're getting more info and understanding..

When i test drove some manuals.. (#4000's and #5031 or so) i did notice that my head was brushing that headliner with my hair.. something i didn't see in the other two automatics (#2300's and #3000's).. then i test drove a later #6630? or #6681 manual and the headroom was fine.. i couldn't figure out what it was.. now i know.. sagging headliner! makes sense..

but why would the automatics have their headliners okay and the manuals would not be (for headroom)?? are they producing these on two different lines? i have heard they produced more autos than manuals.. could this be it too? maybe someone could throw out some ideas of why two different transmission choices would affect the headliner..

Height of seat is due to dealerships not installing them right after they take them out for scotch-guard.........sorry.

that's what i thought too, the scotchguard, but this dealer doesn't do that.. and these cars were all at the same dealer.. only difference was manual/auto.. the VIN didn't see to matter..

ok so, to test your theory.........you must further the breadth of your study to include test drives from another dealer. Now, if the seat height at this dealer is still high in every car........there is a problem.

What exactly is scotchguard. I tried looking it up but I could only find vacation trips, 3M stain remover, etc.

its a fabric conditioner applied to cloth to make it repel stains. Similar (yet far more permanent) to the stuff that you spray sneakers or boots with to waterproof them:)

The second dealer was able to do the fix for the moonroof pop. It is a layer of insulation or something under the moonroof tracks. All better and all good. Ask for this fix and make sure you take it somewhere that has already been in contact with Toyota. The first dealer I took it to just sprayed foam behind the headliner. Idiots. Call and get a case number. Sol is the name of a customer service person at Scion who will help you out - she gets the service people on a conference call with you and makes them give you a loaner car. My vin was in the 4000s.

I'm waiting 'til there's an official Toyota fix for the popping noise before I take my car back to the dealership.
