NHTSA Complaint #10892734 — 2011 NISSAN QUEST

MY 2011 NISSAN QUEST IS HAVING ISSUES WITH THE TRANSMISSION. ON TWO SEPARATE TRIPS THIS SUMMER MY QUEST HAS SEEMINGLY BEEN INCAPABLE OF DOWN SHIFTING TO GAIN POWER DURING PASSING OR CLIMBS. THIS ONLY HAPPENS DURING SEVERAL HOURS OF EXTENDED DRIVING TIME BUT DURING NORMAL AROUND TOWN DRIVING IT OPERATES WITHOUT INCIDENT. I HAVE NOW HAD MY QUEST SERVICED AT TWO SEPARATE DEALERS, ONE IN FLORIDA AND THE OTHER IN OHIO, BOTH FOUND NOTHING AT ALL WRONG. INCIDENT ONE OCCURRED IN LATE JUNE 2016 WHILE IN THE APPALACHIAN'S DURING BOTH THE DESTINATION AND RETURN TRIP (RETURN TRIP AFTER A DEALER TRANSMISSION SERVICE). THE VEHICLE WOULD NOT TRAVEL FASTER THAN 50-60 MPH WHILE CLIMBING EVEN WITH THE ACCELERATION PEDAL COMPLETELY PRESSED. NO ENGINE LIGHTS COME ON AND THE ENGINE TEMPERATURE WAS NORMAL. DRIVING CONDITIONS WERE SIX PASSENGERS WITH LUGGAGE AND 95+ OUTDOOR TEMPS. INCIDENT TWO OCCURRED IN LATE JULY 2016 WHILE TRAVELING IN FAIRLY FLAT MICHIGAN AND OHIO. IN THIS CASE I WAS ABLE TO MAINTAIN 80MPH BUT UNABLE TO ACCELERATE TO PASS. BUT ONE VERY DANGEROUS INCIDENT AND IN FACT ALMOST CAUSING ME TO BE REAR-ENDED WAS WHILE IN STOP AND GO TRAFFIC I TRIED TO ACCELERATE AND CHANGE LANES BUT HAD ZERO POWER PRESSING THE PEDDLE COMPLETELY DOWN. DRIVING CONDITIONS WERE FIVE PASSENGERS WITH LUGGAGE AND LOW 70S OUTDOOR TEMP. I CURRENTLY HAVE A NISSAN CORPORATE ENGINEER SCHEDULED TO EVALUATE MY VEHICLE.
