Hi All,
I happened on mine!. Would you do this test tonight on your RX400h.
-Apply hand brake hard (Actually foot brake!) to make sure the car NOT ROLLING ON IDLE when you release the brake.
-Turn the key to ready mode.
-hold down the brake(just like you start to drive); pull the gear to reverse; release the brake but the hand brake is still hold hard(just like you forgot to release tha hand brake).
-At this time; did you hear the vibration and humming sound?
Mine is happend a few time during a day. If I keep trying for a few time, the noise and vibration gone for a day!!
I would like to know how it react in that condition before I bring my car to the dealer.
Thanks
Huey. :cries:
