NHTSA Complaint #11431646 — 2008 TOYOTA AVALON

This car has a rear window shade that started going up on its on when it is hot outside. I could not locate this feature in the owners manual. I did read that a safety feature for the shade is that when car is placed in reverse the shade is automatically closed. This feature has stopped working, in fact the shade now will not even lower. I used to be able to manually assist the shade down while someone would press the switch but down it raises back up almost immediately. I checked with Google and apparently this is a common problem. I have finally pulled the fuse to keep the shade down permanently.
