THIS A 2004 LX470. IN MAY OF 2005 THE REAR SUSPENSION BECAME "LOCKED" IN A FULLY EXTENDED MODE. THE 2004 LX470 HAS AN ELECTRONICALLY CONTROLLED SUSPENSION THAT CAN CAUSE THE VEHICLE TO LOWER OR RAISE. APPARENTLY, THE REAR SUSPENSION WAS "LOCKED" IN THE RAISE POSITION WHILE THE FRONT SUSPENSION WAS IN THE LOWERED POSITION. THE VEHICLE WAS DANGEROUS TO DRIVE AND WAS SUBSEQUENTLY FLAT-BEDDED TO A DEALERSHIP FOR REPAIRS. AT THE DEALERSHIP THEY WERE NOT ABLE TO GET NEW REPLACEMENT PARTS (THEY SAID IT WAS BAD SENSORS ) BECAUSE THEY WERE ON BACK ORDER. 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 DANGEROUS TO DRIVE. I HAVE CONTACTED LEXUS WHO HAS SAID THEY WILL NEED TO INVESTIGATE THE ISSUE. HOPEFULLY THIS WILL BE REPAIRED PROPERLY THIS TIME AND NEVER OCCUR AGAIN. *JB
