2010 NISSAN MAXIMA Power Trainautomatic Transmission Problems

ON 3 OCCASIONS, WHEN TRYING TO STOP THE CAR FROM A SLOW SPEED, THE THROTTLE FAILED TO DISCONNECT. I WAS ABLE TO SLOW THE CAR DOWN FROM 25 MPH TO 3MPH, BUT I COULD NOT GET IT TO STOP UNTIL I PUT IT INTO NEUTRAL. WHEN I DID THAT, THE ENGINE RACED JUST LIKE IT WOULD IF YOU WERE ON THE GAS AND SHIFTED TO NEUTRAL. I HAVE HAD THE CAR FOR 13 MONTHS AND THIS DID NOT HAPPEN UNTIL2 MONTHS AGO, AND HAS NOW HAPPENED 3 TIMES. OF COURSE, NISSAN CAN'T REPLICATE AND SAYS THERE IS NOTHING WRONG. ONLY HAPPENED AT SLOW SPEED AND WITHIN 5 MINUTES OF STARTING THE CAR AFTER SITTING FOR SEVERAL HOURS.. WEATHER WAS ABOVE 70 ALL 3 TIMES. *TR

PURCHASED A NEW 2010 NISSAN MAXIMA. THIS PAST WEEKEND, 4-3-11 WHILE TRAVELING ENGINE DEVELOPED A LOUD SOUND LIKE METAL TO METAL GRINDING OR LOUD MUFFLER. CAR TAKEN TO THE DEALERSHIP TO HAVE CHECKED, HAS BEEN THERE FOR 4 DAYS AND YESTERDAY WE WERE INFORMED THAT THE TRANSMISSION NEEDED REPLACED. EXTREMELY LOW MILEAGE ON THIS MODEL & NO EXCUSE FOR THIS TRANSMISSION TO BE BAD ALREADY! IT APPEARS THERE HAVE BEEN OTHER REPORTS OF TRANSMISSIONS GOING BAD IN THE NISSAN MAXIMA, CAN THIS BE INVESTIGATED?? *TR

WHILE DOING NORMAL DRIVING, ON TWO OCCASIONS, ONE COMING DOWN A SLIGHT HILL AND PLANNING TO STOP AT A CORNER, AND ONCE WHEN PULLING INTO MY CARPORT, WITH FOOT LIGHTLY ON THE BRAKE, I NOTICED THE ENGINE RACING AT 2000 RPM OR SO, TRYING TO ACCELERATE. WAS ABLE TO HOLD CAR WITH FOOTBRAKE, AND, AFTER STOPPING, PROBLEM DID NOT SEEM TO REPEAT IMMEDIATELY. *TR
