NHTSA Complaint #10504783 — 2011 HYUNDAI TUCSON

COMMENT: I HAVE BROUGHT IN MY TUCSON FOR THE CLUNKING TRANSMISSION ISSUE 5 TIMES NOW. EACH RETURN TO THE SERVICE CENTER RESULTS IN A CANNOT DUPLICATE RESPONSE. 1. ON THE MORNING OF 28 MARCH 2013, APPROXIMATELY 20 SECONDS AFTER STARTING THE VEHICLE THE TRANSMISSION WAS SHIFTED INTO DRIVE, A LOUD MECHANICAL CLUNK WAS HEARD AND FELT FROM THE DRIVER'S SEAT, THE TRANSMISSION DID NOT RESPOND, THE VEHICLE WOULD NOT MOVE WHEN THE GAS PEDAL WAS DEPRESSED, AND THE P,R,N,D INDICATOR IN THE DASH BOARD DISPLAY WENT BLANK. THE CAR WAS SHIFTED INTO P, A LOUD MECHANICAL CLUNK' WAS HEARD AND FELT FOLLOWED BY A LOUD CRUNCH'. THE IGNITION WAS TURNED OFF, AND THE VEHICLE WAS RESTARTED WITH NO ISSUES ONCE THE VEHICLE WAS WARMED UP. 2. RECALL SERVICE FOR THE TRANSMISSION COOLING LINE COUPLING PERFORMED, THE VEHICLE BEGAN EXIBITING THE TRANSMISSION DISENGAGE AND REENGAGE SYMPTOM WHILE DRIVING UNDER ACCELERATION. THIS OCCURS APPROXIMATELY ONCE A DAY UNDER ANY INCLINE OR FLAT CONDITION WHILE ACCELERATING. 3. WHILE ACCELERATING UP HILL, SPECIFICALLY UP HILL WHILE ACCELERATING UP TO 45 MPH THE VEHICLE WILL DOWN SHIFT TO CLIMB THE HILL. UNDER 2 CONDITIONS 1. CRUISE CONTROL ENGAGED, 2. CONSTANT ACCELERATOR PEDAL APPLICATION.THE VEHICLE WILL NOT RE-UPSHIFT ONCE THE HILL HAS BEEN COMPLETED AND KEEPS AN ELEVATED RPM RANGE OF APPROXIMATELY 3000 RPM EVEN WHILE ON LEVEL GROUND WHILE PASSING TAX AND REVENUE. THE RPMS DO NOT LOWER AND THE TRANSMISSION WILL NOT UP SHIFT UNTIL EITHER THE BRAKE PEDAL IS DEPRESSED (TO DISENGAGE THE CRUISE CONTROL), OR THE ACCELERATOR IS LIFTED. NOTE: THE ENTIRE TIME THIS SITUATION IS OCCURRING THE ECON GREEN LIGHT IS ILLUMINATED.. THE SAFETY ISSUE IS THAT THE TRANSMISSION INTERMITTENTLY DISENGAGES WHILE DRIVING, SOMETIMES WHILE DEPARTING INTERSECTION. THE TRANSMISSION ROBLEM HAS CONTINUED AND GROWN WORSE WITH EXAPNDING PROBLEMS. *TR
