2013 TL sunroof question
 

I just picked up a 2013 TL. I notice when I look up at the sunroof I can see a spot on each side of the track where there is heavy grease. Is this normal?

Pretty sure that's part of the rails, and there should be a decent amount of grease there to keep things moving smoothly and quietly. Mine has a similar amount. If you wiped it off you can replace it with anything like Super Lube silicone grease.

Take that blob of grease out and put it some white lithium grease.
