2004 Lexus LX Suspension Problems

NORMAL DRIVING, THEN SUV BECAME VERY BOUNCY. AIR SUSPENSION SYSTEM FAILED CAUSING DEFAULT TO HIGHEST SUSPENSION LEVEL. NO SUSPENSION CHARACTERISTICS AT ALL GOING OVER BUMPS OR MAKING TURNS. THE WHOLE CAR WOULD SHAKE AND BOUNCE OVER ANY SLIGHT IMPERFECTION IN THE ROAD. THE CAR FELT LIKE IT WOULD TIP OVER GOING AROUND TURNS. FIRST TIME THIS HAPPENED AT 10,000 MILES. AT THAT TIME THE DEALER REPLACED UNDER WARRANTY THE REAR SENSORS THAT HAD FAILED. BOUGHT THE CAR BACK TO THE DEALER TODAY. THEY COMFIRMED THAT ONE OF REAR SENSORS HAVE FAILED AGAIN AND BOTH OF THE FRONT SENSORS HAVE FAILED. CAR HAS 48,700 MILES. *TR

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. SOMETIMES THE CAR WILL COME UP A BIT, BUT THEN GOES BACK DOWN. IF THE LIGHT SAYS THE CAR IS IN THE "N" POSITION, IT IS NOT. IT IS NOW IN THE LOW POSITION. THE CAR DOES NOT COME UP EVEN WHEN ONE IS AT SPEED. ON OCCASION THE CAR'S REAR END WILL BE ALL THE WAY DOWN AND THE FRONT END IS IN THE NORMAL POSITION, WHICH PUTS THE HEADLIGHTS VERY HIGH. WHEN THE CAR IS IN THE LOW POSITION, AS IT IS PRESENTLY, THERE IS VERY LITTLE SUSPENSION TRAVEL AND VIRTUALLY NO WAY TO CONTROL THE VEHICLE IN A SUDDEN MANEUVER. IN ADDITION, THE CAR WILL OSCILLATE FROM FRONT TO BACK AS IF IT WERE A BOAT GONG INTO WAVES. I CALLED LEXUS CUSTOMER SERVICE. I GOT A VERY POLITE PERSON, BUT NO REAL EXPLANATION OR HELP. I NOW HAVE AN APPOINTMENT WITH THE LOCAL LEXUS DEALER TO GET THE CAR REPAIRED. HOWEVER, I FEEL THIS TYPE OF SUSPENSION SYSTEM FAILURE IS AN "EXTREME SAFETY HAZARD". THESE CARS SHOULD BE RECALLED BEFORE SOMEONE GETS INJURED OR KILLED. SHOULD A SUSPENSION FAILURE OCCUR AT HIGHWAY SPEED, THE CAR COULD EASILY GO OUT OF CONTROL. *TR

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
