First post - found this thread - just got a used IS250 (2007) and it seems to have the same sunroof issue....
Opens fine - to any position.
Attempt to close - goes about 9/10ths shut and auto-reverses.
However - it does that when stopped /parked/standing still.
When the car is in motion - it closes all the way.....every time.
1. Can you point me to the thread about resetting the sunroof ECU (sorry haven't been able to search/find that one yet)
2. Is this the same symptions (and have you tried shutting the sunroof while the car is moving?)
Thanks
