Transmission failed to go in gear briefly when starting in traffic. . . . Felt like the vehicle revved up, but no power. After a few seconds, it went in gear.
I bought a used 2015 Nissan Altima on 6/23/2017 with approx. 47,000. Around 6/30/17 the car would not accelerate while driving over 40mph and the rpm was going all the way over to 8 & 9. The car sounded like it was not shifting into gear. I had to pull over, cut off the car and crank it back up again. There have been several times since then, when I'm at a light that the car will not accelerate over 5-10 mph and I have the pedal pushed all the way down to the floor. I took it to the Nissan in tuscaloosa, al on 08/21/17 to correct the cvt transmission open recall. I'm not sure if this will solve the problem due to them not finding any codes and test driving the car. I thought the transmission had blown up on 08/21/17 and had to immediately pull over (my son was in the car) on the side of the road.
