2010 INFINITI G37 Engine And Engine Cooling Problems

LEASED THE VEHICLE BACK ON 2010 OF OCTOBER. 6 MONTHS LATER I HAD ISSUES WITH ACCELERATION ON 4 DIFFERENT OCCASIONS AT ALL TIMES OF THE DAY. EVEN WHEN FOOT IS LIGHTLY PUSHED ON THE GAS PEDAL CAR RPM REVS FROM 1 TO 7 QUICKLY. UNCOMFORTABLE SINCE YOU DON'T KNOW WHEN TO ACCELERATE HARD OR SOFT. SCARY WHEN DRIVING SHORT DISTANCE WITH STOP AND GO MOTION. ENGINE AT TIMES IS UNPREDICTABLE. CAR ALSO SHUT DOWN ON ME SEVERAL TIMES WHILE DRIVING ON BUSY ROADS. CAR IS ONLY 1 1/2 YEARS OLD. THIS ISSUE NEEDS TO BE INVESTIGATED. *TR

WHILE STOPPED AT A PARKING LOT EXIT PRIOR TO TURNING, MY FOOT WAS ON THE BRAKE AND THE ENGINE STARTED RACING. THE CAR STARTED ROLLING FORWARD EVEN WITH THE BRAKES FIRMLY APPLIED. I PUT THE CAR IN PARK, BUT THE ENGINE CONTINUED TO RACE. I TURNED THE CAR OFF. I RESTARTED THE CAR, AND THE ENGINE RAN NORMALLY. A SIMILAR INCIDENT HAPPEND TO ME IN THE SAME CAR ABOUT A YEAR AND A HALF AGO IN A PARKING LOT. THE ENGINE STARTED RACING WHILE BACKING UP. I PUT THE CAR IN PARK AND TURNED THE ENGINE OFF. THE CAR RAN FINE WHEN I RE-STARTED THE CAR. *TR
