Yeh but then they will have to fix that and give me some free gas :D

 

We recently purchased our tC. It has a creaking noise from the rear; we have noticed the most common time this happens is when the suspension is articulated (as when traveling over uneven levels of road surface. We believe it is associated with chassis flex. I would like to hear more from other owners to see if this problem is common. We have begun to design sway bars and upper/lower bars, we will post after we test with these items to see if our hypothesis is correct.

 

If you do some searching on this forum, you will see that this has come up before.

There are 2 screws/bolts on the front side of the Moonroof that aren't tightened properly (torqued enough). Depending on who you talk to at Toyota, this is a known issue. Toyota is in the midst of sending out an alert to all dealerships with the fix for this problem. In the meantime, if you contact your service center, and tell them about it and bring the car in, I'm sure they can make a few phonecalls and confirm this with someone from Toyota (if they really wanted to). It isn't the glass, but it's the front of the housing or something and since it isn't tight, there is more movement than intended or something along those lines.

 

I have done exactly that - brought it into the dealer and told them to tighten the two bolts on the moonroof and the problem has not gone away. In fact, I think the cracking has become more consistent. It's such a scary noise when you hear it and it definitely sounds like it's associated with chassis flex as stated above. Hopefully a TSB will be out soon enough.
