NHTSA Complaint #10509313 — 2013 LEXUS CT

DESIGN DEFECT: TURN SIGNAL FAILS TO CANCEL AFTER A SWEEPING TURN (E.G., RIGHT OR LEFT TURN FROM 2ND LANE, OR A "CORNER CUT" YIELD-TYPE TURN). SAFETY ISSUE IS THAT A NON-CANCELLED TURN SIGNAL CAN THEN CAUSE OTHER DRIVERS TP BELIEVE YOU WILL BE TURNING, WHEN NO SUCH TURN IS CONTEMPLATED. THIS VEHICLE EMPLOYS "PROGRESSIVE STEERING", WHICH MEANS THAT STEERING WHEEL ROTATION IS PROGRESSIVELY MAGNIFIED IN THE TURN OF THE FRONT WHEELS. IT APPEARS THIS MINIMAL STEERING WHEEL MOVEMENT REQUIRED FOR A SWEEPING TURN WAS NOT CONTEMPLATED IN THE PLACEMENT OF THE TURN SIGNAL CANCELLATION MECHANISM ON THE STEERING COLUMN. BEST SOLUTION WOULD BE TO REPOSITION THE AUTO-CANCELLATION TABS SO THAT ALL TURNS WOULD PROPERLY CANCEL. SECONDARY -- EASIER & CHEAPER -- REMEDY WOULD BE TO ADD A PROFOUNDLY AUDIBLE INTERIOR SIGNAL FOR A SIGNAL LEFT UNCANCELLED FOR GREATER THAN (20?) SECONDS. *TR
