DAMAGE TO SECONDARY RADIATOR CAUSED COOLANT LEAK. SECONDARY RADIATOR IS NOT SUFFICIENTLY SHIELDED OR PROTECTED FROM DEBRIS. THERE WAS NO VISIBLE DEBRIS ON THE ROAD LEADING ME TO BELIEVE SOMETHING AS MASSLESS AS A LARGE BUG COULD HAVE CAUSED THE DAMAGE. CAR WAS TOWED TO DEALER AND REPAIRED. *TR

THE 2010 AUDI A4 2.0T WHICH I LEASED LUNGES FORWARD EVERY TIME IT IS DOWN SHIFTED IN TRIPTRONIC MODE (MANUALLY SHIFTING THE AUTOMATIC TRANSMISSION). TODAY, I REPORTED THE DEFECT TO THE SERVICE WRITER SCOTT SUMMERFIELD AT MCDONALD AUDI IN LITTLETON CO AND HE TOLD ME HE WAS AWARE OF IT AND THAT HE THOUGHT AUDI MIGHT BE WORKING ON A "FIX" FOR IT. I THINK YOU SHOULD COMPEL AUDI TO REPLACE THE TRANSMISSIONS BECAUSE THE LUNGING IS A POTENTIALLY LIFE THREATENING DEFECT. THE MANUAL SHIFTING MODE OF THE AUTOMATIC TRANSMISSION IS USED MAINLY ON UNSAFE STEEP MOUNTAIN ROADS TO AVOID RIDING THE BRAKE ON A DOWNHILL GRADE AND TO ACQUIRE GREATER CONTROL OF THE VEHICLE ON SLIPPERY TERRAIN WHERE THE POSSIBILITY OF A FATAL ACCIDENT SUCH AS GOING OVER A CLIFF IS GREAT. *TR
