2004 LX470 AHC (AUTOMATIC HEIGHT CONTROL FAILURE)! AS OF JANUARY 22, 2008, THE AHC FAILED. THE CAR NOW RIDES LIKE A BUCKBOARD; EVEN THOUGH ONE IS ON THE HIGHWAY. THE CAR WILL EVEN TILT TO ONE SIDE WHILE GOING DOWN THE ROAD. THE CAR SITS VERY LOW AND THE HEIGHT WILL NOT COME UP TO THE "N" LEVEL AND STAYS IN THE LOW POSITION. THE "ACH OFF LIGHT" KEEPS FLASHING.

AFTER ABOUT A MONTH OF DELAY, THE DEALERSHIP FINALLY USED SENSORS FROM A 2005 VEHICLE TO REPAIR MY VEHICLE. NOW, LESS THAN ONE YEAR LATER (AND LESS THAN 10,000 MILES LATER) ON FEB. 26TH OF 2006 THE SAME THING HAS OCCURRED YET AGAIN. THE REAR SUSPENSION IS "LOCKED" IN THE FULLY EXTENDED POSITION MAKING THE VEHICLE...
