I have a random-acting BUC myself. 75%ok, 20% blinking on and off, 5% blacked out.
Of course when you take this to the dealer, it works fine.
There is no pattern of failure like, 'when raining", 'after car wash", "just bounced down a dirt road", "opened hatch X times".
Usually it blanks when I really want it like backing an unfamiliar driveway at night.............
Find myself wishing it would fail completely so we can find the crummy connection..........
