2012 NISSAN QUEST Engine And Engine Cooling Problems

MY NEW 2012 NISSAN QUEST WAS PARKED IN MY DRIVEWAY WITH THE FRONT SLIGHTLY FACING DOWN LOOKING AT THE ROAD WITH LESS THAN QUARTER TANK OF GAS. THE VAN WOULD START BUT WOULD NOT STAY IDLE AND THE DASH BOARD INDICATED THAT THE VAN HAD ENOUGH GAS TO GO 25 MILES. I HAD TO PUT THE VAN IN NEUTRAL TO ROLL IT DOWN THE STREET (FLAT SURFACE) BEFORE IT CAN BE STARTED AND KEPT ON IDLE. WHEN YOU ROLL THE VAN DOWN IN NEUTRAL WITH THE ENGINE OFF YOU LOOSE YOUR POWER BRAKES, SO I HAD TO MAKE SURE THERE WERE NO CARS COMING FROM EITHER SIDE. I REPORTED THE INCIDENT TO THE NISSAN DEALER, ALSO FILED A COMPLAINT WITH THE MANUFACTURER, AND THE DEALER KEPT THE CAR FOR COUPLE OF DAYS BUT COULD NOT FIND ANYTHING WRONG WITH IT. I WAS TOLD BY THE DEALERSHIP THAT NISSAN ENGINEERING TEAM...

PURCHASED A BRAND NEW 2012 NISSAN QUEST JUST WEEKS AGO, CURRENT MILEAGE 320. ENGINE STALLED WITH LITTLE LESS THAN QUARTER TANK OF GAS IN A SLOW TURN. COMPUTER INDICATED THAT THE VAN HAD ENOUGH GAS FOR 30 MILES TRAVEL. LUCKILY THERE WAS NO CARS BEHIND US, SO I WAS ABLE TO APPLY THE BRAKE AND RESTART THE CAR TO THE NEAREST GAS STATION. CONTACTED THE SERVICE DEPARTMENT THE NEXT DAY, THE SERVICE ADVISER ADVISED ME TO MAKE SURE NOT TO LET THE GAS TANK GO DOWN BELOW 1/4 TANK. AFTER READING ALL OTHER COMPLAINTS FROM CURRENT QUEST OWNERS, I WILL BE CONTACT THE MANUFACTURER, INCLUDING THE DEALERSHIP FIRST THING TOMORROW. I AM NOT SURE IF I CAN RETURN THE VEHICLE, EVENTHOUGH IT HAS BEEN LESS THAN 30 DAYS SINCE THE PURCHASE DATE.
