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. - Mar 6, 2019 · 101,000 milesSteering
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. - Mar 7, 2018 · 168,022 milesEngine

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 - Dec 13, 2017 · 151,000 milesEngine
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… - May 12, 2015 · 50,000 miles · crash · 1 injuryAir bags

THE HYBRID COMPUTER SYSTEM SHORTED DUE TO A LEAK WHERE THE ROOF RACK CONNECTS TO THE ROOF. THIS COMPUTER IS BELOW THE REAR SEAT AND IS NEXT TO THE HYBRID BATTERIES. THIS COMPARTMENT SHOULD BE SEALED TO PREVENT WATER INTRUSION, AND IN NO SITUATION SHOULD WATER FROM THE ROOF BE ABLE TO REACH THIS COMPARTMENT. WATER ENTERING THIS AREA IS EXTREMELY DANGEROUS AND COULD CAUSE A FIRE OR THE CAR TO CEASE FUNCTIONING CORRECTLY WHILE IT IS IN MOTION. - Sep 6, 2015Hybrid propulsion system
