NHTSA Complaint #11207097 — 2013 SUBARU BRZ

2013 SUBARU BRZ 2.0 LIMITED. I AM THE ORIGINAL OWNER. FACTORY RECALL RELATING TO FA20 VALVE SPRING REPLACEMENT COMPLETED BY SHERMAN OAKS (CALIFORNIA) SUBARU IN APRIL 2019. (DROPPED CAR OFF FOR REPAIR MONDAY, 4/15/2019, RECEIVED CAR FROM DEALERSHIP ON WEDNESDAY 4/24/2019) AFTER RECEIVING CAR, FOLLOWING VALVE SPRING REPLACEMENT, NOTED SIGNIFICANT DECREASE IN AVG MPG AS REPORTED BY CAR (AVERAGE WAS 25-26 MPG BEFORE RECALL REPAIRS. THIS HAD BEEN STABLE FOR YEARS. IMMEDIATELY AFTER REPAIR AVERAGE MPG AS REPORTED BY CAR WAS AROUND 14MPG.) DEALER ADVISED LEAVING CAR WITH THEM FOR DIAGNOSIS & REPAIR. RETURNED CAR TO SHERMAN OAKS SUBARU MONDAY 5/5/2019; RECEIVED CAR FROM DEALERSHIP SATURDAY 5/11/2019. DEALERSHIP'S DIAGNOSIS FAILED TO IDENTIFY A CAUSE, SEVERAL SYSTEMS CHECKED WITH NO REMARKABLE FINDINGS, "RESET OF TRIP METERS" REPORTED TO PRODUCE AVG MPG "27-30" ON DEALERSHIP'S TEST DRIVE. WHEN I PICKED UP THE CAR, CAR REPORTS ACTUAL AVERAGE MPG OF 23.3 (!); NOT "27-30" AS DESCRIBED TO ME AND STILL MARKEDLY LOWER THAN PRE-VALVE SPRING REPAIR AVERAGE MPG. AFTER DRIVING 21.9 MILES, AVERAGE MPG DECREASED FURTHER TO 22.2. SOMETHING IS CLEARLY WRONG WITH THE ENGINE FOLLOWING RECALL REPAIR. BECAUSE THERE ARE MANY ONLINE REPORTS OF SERIOUS FAILURES (E.G. FIRE, ENGINE STALLING AND THEN UNSTARTABLE) AS MILEAGE POST-REPAIR ACCUMULATES, I AM CONCERNED ABOUT DRIVING MY BRZ. (PDFS OF RELATED DEALERSHIP WORKORDERS ARE AVAILABLE IF THEY WOULD BE HELPFUL TO YOU.)
