I AM THE OWNER OF A LEXUS 2008 GS450H AND TAKE EXCELLENT CARE OF MY VEHICLE. ON JUNE 10, 2017, I TOOK MY CAR TO THE LEXUS OF ROSEVILLE DEALERSHIP IN ROSEVILLE, CALIFORNIA FOR THE 80K MILE SERVICING.. NO OTHER WORK WAS PERFORMED ON MY VEHICLE BETWEEN JUNE 10 - AUGUST 29, 2017 AND NO ONE WAS EVEN UNDER THE HOOD OF THE VEHICLE. LEXUS OF ROSEVILLE IS RESPONSIBLE FOR THE DAMAGE, SUBSEQUENT EXPENSES TO REPAIR AND RELATED EXPENSES. AS I AM SURE YOU ARE AWARE, PART OF THE LEXUS MULTIPOINT INSPECTIONS REQUIRES SERVICE PERSONNEL TO PERIODICALLY INSPECT AND ADJUST THE ENGINE COOLANT (RADIATOR) AND RADIATOR CAP TO DETERMINE WHETHER IT NEEDS REPLACEMENT OR REPAIR. THE ATTACHED SERVICE HISTORY REFLECTS THAT THIS SIMPLE INSPECTION WAS NEVER COMPLETED DURING THIS JUNE 10, 2017 SERVICING. ON AUGUST 29, 2017, WHILE DRIVING TO ARIZONA FROM CALIFORNIA, THE RADIATOR CAP FAILED CAUSING THE ENGINE TO OVERHEAT. I WAS STRANDED 90 MILES NORTH OF THE NEAREST TOWN IN 110-DEGREE HEAT WITH SUBSTANDARD CELL PHONE SERVICE. THIS OVERHEATING CAUSED SUBSTANTIAL ENGINE DAMAGE WHICH MADE THE VEHICLE INOPERABLE. IT WAS NECESSARY TO REPLACE THE ENTIRE ENGINE. MY CAR WAS TOWED TO BELL LEXUS NORTH SCOTTSDALE, ARIZONA. IT WAS DAYS BEFORE THE ENGINE WAS REPLACED AND THE VEHICLE RETURNED TO ME IN AN OPERABLE CONDITION. THE NEGLIGENCE OF LEXUS OF ROSEVILLE IN SERVICING MY LEXUS CAUSED THE DAMAGE BY FAILING TO CONDUCT THE SIMPLE INSPECTION WHICH WOULD HAVE PREVENTED THIS DAMAGE FROM OCCURRING. THIS WAS CONFIRMED BY BELL LEXUS NORTH SCOTTSDALE. I WAS REQUIRED TO HAVE THE VEHICLE TOWED AND TO STAY IN A HOTEL DURING THE REPAIR. THESE WERE EXPENSES I WOULD NOT HAVE INCURRED IF THIS INCIDENT HAD NOT HAPPENED. DEMAND IS MADE FOR REIMBURSEMENT OF THE ABOVE EXPENSES IN THE AMOUNT OF $9,685.38. I AM VERY HOPEFUL TO RESOLVE THIS MATTER IN A RESPECTABLE AND AMICABLE FASHION.
