NHTSA Complaint #10957717 — 2012 NISSAN ALTIMA

DRIVING AT HIGHWAY SPEEDS CAR ENGINE SUDDENLY REVVED TO APPROX. 5000 RPM. PULLED OVER AND UPON ACCELERATING AGAIN THE CAR WOULD DRIVE BUT THE ENGINE REVVED VERY HIGH AND THE CVT WOULDN'T CHANGE GEAR RATIOS ("SHIFT") AS IT NORMALLY DOES. REALIZED CAR WOULD ACCELERATE AND NOT REV AS HIGH IF I ACCELERATED EXTREMELY SLOWLY. CAR HOWEVER IS EXTREMELY DANGEROUS TO DRIVE AT THIS POINT. ALSO COULDN'T DRIVE ABOVE 55 MPH WITHOUT THE ENGINE REVVING VERY HIGH APPROACHING REDLINE. AFTER APPROX 5 MORE MILES OF DRIVING THE "SERVICE ENGINE" LIGHT CAME ON AND I SCANNED THE CODE. SHOWING CODE P1778 WHICH APPEARS TO BE A STEPPER MOTOR PROBLEM WITH THE CVT. CALLED DEALER AND SOUNDS LIKE THEY DON'T FIX CVT, JUST REPLACE FOR BETWEEN $4000-$5000. VERY DISAPPOINTED NISSAN HASN'T RESOLVED THESE PROBLEMS YET AND THAT THEY TREAT A $5000 PART AS A REPLACEMENT ITEM AND NOT ONE THAT CAN BE FIXED.
