Most Recent Complaints
The contact owns a 2010 Lexus RX450H. The contact stated that while driving at an undisclosed speed, the engine cooler line fractured and the vehicle lost oil very quickly. No warning lights were illuminated. The vehicle was towed to the dealer to be diagnosed. The contact was informed that the engine cooler line needed to be replaced. The manufacturer was made aware of the failure, but the vehicle was out of the warranty. The failure mileage was 185,000.
OUTER MIRROR, DRIVER'S SIDE, TURNS DOWN WHEN PLACED IN REVERSE AND WILL STAY IN THE DOWN POSITION. OCCASIONALLY IT WILL TURN DOWN ON ITS OWN WHEN CHANGING FROM PARK. WHEN GOING TO DRIVE, THERE IS NO WAY TO SEE ONCOMING TRAFFIC ON THE LEFT WITHOUT TURNING HEAD AND LOOKING: SOMETHING A DRIVER ISN'T EXPECTING. THIS ALWAYS OCCURS GOING FROM STATIONARY TO MOTION. OCCURANCE IN RANDOM.
THE STEERING LOCK ACTUATOR FAILED IN THE LOCKED POSITION WHILE THE VEHICLE WAS STATIONARY. ALTHOUGH IN THIS INSTANCE THERE WAS NO SAFETY HAZARD, IT SEEMS POSSIBLE THAT THIS FAILURE COULD HAVE OCCURRED WHILE THE VEHICLE WAS IN MOTION, WHICH WOULD HAVE CAUSED THE STEERING TO LOCK AND CONSEQUENT LOSS OF CONTROL OF THE VEHICLE. I INFORMED LEXUS US ABOUT THIS FAILURE.
TL *THE CONTACT OWNS A 2010 LEXUS RX450H. WHILE DRIVING 55 MPH, THE OIL FROM THE ENGINE DEPLETED AND THE ENGINE SEIZED WITHOUT WARNING. THE VEHICLE WAS TOWED TO SEWELL LEXUS IN FORT WORTH, TEXAS WHERE IT WAS DIAGNOSED THAT THE OIL COIL HOSE RUPTURED, WHICH DEPLETED ALL OF THE OIL, AND THE ENGINE SEIZED AND FRACTURED. HENDRICK LEXUS KANSAS CITY IN MERRIAM, KANSAS AND THE MANUFACTURER WERE MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 168,022. *TT
I HAVE BEEN A LOYAL LEXUS OWNER FOR SEVERAL YEARS AND HAVE METICULOUSLY MAINTAINED MY VEHICLE AT ONLY LEXUS DEALERSHIPS. WHILE OPERATING THE VEHICLE 10 DAYS AGO, THE OIL COOLER HOSE BURST, WHICH COULD HAVE RESULTED IN A MAJOR SAFETY ISSUE (ENGINE FAILURE/SEIZURE WHILE DRIVING) WITH CATASTROPHIC ENGINE FAILURE. LEXUS HAS KNOWN ABOUT THIS ISSUE AND HAS COVERED IT FOR MANY OTHER VEHICLES WITH 150K MILES OR LESS, HENCE THE "ENHANCED WARRANTY" ABOUT WHICH I HAD NO KNOWLEDGE. I HAVE 151K MILES AND THEY REFUSE TO COVER IT OR OFFER ANY KIND OF COMPENSATION FOR THE EXPENSE OF REPLACING THE HOSE. THEY DO NOT DEEM IT A SAFETY ISSUE, WHICH IS ABSURD FOR THE REASON STATED ABOVE. APPARENTLY THERE WAS A WARRANTY "ENHANCEMENT" OFFERED A COUPLE OF YEARS AGO, ABOUT WHICH I WAS NEVER MADE AWARE, BY LEXUS OR BY ANY OF THE TECHNICIANS WHO HAVE SERVICED MY CAR OVER THE YEARS. IF LEXUS OFFERED THIS WARRANTY, THEY CLEARLY KNEW THIS WAS A POTENTIAL ISSUE WITH THIS VEHICLE. NOW THAT THE ISSUE HAS HAPPENED TO MY CAR, THEY WON'T COVER IT, AS I'M "OUT OF WARRANTY" WITH A WARRANTY I NEVER KNEW WAS OFFERED TO ME IN THE FIRST PLACE. I WILL NEVER OWN ANOTHER LEXUS - THEY HAVE LOST MY BUSINESS AND MY TRUST,
