NHTSA Complaint #11240506 — 2012 NISSAN ALTIMA

WHILE IN MOTION, THE VEHICLE BEGINS TO DRASTICLY SLOW DOWN FROM SPEEDS OF 60 TO 70 MPH DOWN TO 20 TO 30 MPH. THIS USUALLY HAPPENS DURING THE DAY AFTER DRIVING FOR AN HOUR + AND IN ANY KIND OF INCLINE ROAD. AT HARD INCLINES I CAN BEARLY DRIVE UPWARD EVEN HHAVING TO COME TO A COMPLETE STOP. THE RPM GAGE BEGINS TO JUMP RAPIDLY TO 5 AND 6 RPM WHEN EVEN SLIGHTLY PRESSING THE GAS PEDDLE, AND ONCE IT ADJUST , THE VEHICLE WILL NOT GO MORE THAT 3 RPM WHILE STILL AT A MPH SLOWER THAN 30. THIS WILL STAY FOR THE REMAINDER OF THE DRIVE UNTIL I HAVE STOPPED AND TURNED MY VEHICLE OFF FOR A SIGNIFICANT AMOUNT OF TIME. TBIS BEGAN HAPPENING AT 100,000 MILES AND NOW AT 150,000 MILES IT HAPPENS VERY FREQUENTLY. I FEEL THIS IS UNACCEPTABLE, AND CLEARLY VERY UNSAFE FOR DRIVING LONG DISTANCES ON LARGE HIGHWAYS, WHEN MY VEHICLE SHOULD WORK AS IT SHOULD.
