2011 Infiniti G37

AS I WAS WAITING TO CROSS A MAJOR HIGHWAY JUNCTION IN UPPER MARLBORO, MD, I ALMOST HAD A COLLISION AFTER CROSSING THE HIGHWAY DUE TO WHAT I SUSPECT A FAULTY TRANSMISSION WITH HESITATION IN SHIFTING. THERE WAS A SUV WAITING TO TURN AND WHILE I HAD THE RIGHT OF WAY, THEY PULLED OFF AND AS MY CHANCE TO CROSS THE 2 LANE HIGHWAY, THEY DID TOO. I PUNCHED THE GAS AND IN THE MIDDLE OF THE ROAD, THE ENGINE TOOK A FEW SECONDS TO GET INTO GEAR SO I LITERALLY WAS IN THE ROAD OF ONCOMING TRAFFIC THAT WAS DRIVING AT SPEEDS IN EXCESS OF 55+ MPH. IT HAPPENED WITHIN 5 SECONDS BUT AFTER I CROSSED AVOIDING A FRONT AND SIDE COLLISION, I PULLED OFF THE ROAD BECAUSE I WAS SHAKING. OTHER INSTANCES WHILE DRIVING AT HIGHWAY SPEEDS THAT I PULL INTO THE LEFT HAND LANE TO PASS A CAR IN FRONT OF ME AND THE ENGINE IS SLOW TO RESPOND AS IT ACCELERATES FROM A LOW GEAR RESULTING IN A LAGGING SOUND/ READING OF THE TACH JUMPING AROUND AS I'M NEARLY HIT FROM BEHIND BECAUSE THE CARS HESITATION IN ACCELERATING. I'M ALSO HEARING THE ENGINE REV UP WITH NO TAKE OFF, SHIFTING IN DRIVE SPORT (DS) MODE IS NOT RESPONSIVE AND EVEN USING THE PADDLE SHIFTERS ISN'T ANY BETTER. I FEEL THIS CAR IS GOING TO BE A DETRIMENT IF INFINITI DOESN'T ADDRESS THE PROBLEM WITH THE 7 SPEED AT. IT HAPPENS UNDER LIGHT ACCELERATION ON THE 3-4 OR/AND 5-6 UPSHIFT. I EVEN SMELLED THE ENGINE AFTER I GOT OUT OF THE CAR AFTER DRIVING TO THE STORE THAT WAS IN MEDIUM/ LIGHT TRAFFIC ABOUT 20 MINUTES. *TR
