NHTSA Complaint #10670121 — 2013 NISSAN ALTIMA

I HAVE THESE ISSUES EVERYDAY DRIVING THIS CAR. SHUTTERING AT LOW RPM WHEN ACCELERATING OR DECELERATING, NOTICEABLE DELAY IN GEARS SHIFTING WHEN SHUTTERING IS OCCURRING BETWEEN 1200 AND 1800 RPM. RPM'S INCREASE RAPIDLY(SHARP SPIKE) WHEN CAR IS GOING DOWN HILL BUT DOES NOT ALLOW THE CAR TO GAIN SPEED. THE RAMPING OF RPM'S IS LOUD AND RESEMBLES WHEN YOU HIT GAS TO ACCELERATE TO ENTER A HIGHWAY ONLY YOU ARE NOT GETTING THE ACCELERATION IN SPEED. ALSO COMING UP HILL THE CAR GIVES OFF A BURNING SMELL. I HAVE NOT LOCATED THE SOURCE OF THE BURNING SMELL AND IT GOES AWAY AFTER GOING BACK TO FLATTER TERRAIN FOR AWHILE. THE SMELL LINGERS ENOUGH TO CAUSE CONCERN. *TR
