NHTSA Complaint #11639611 — 2020 NISSAN TITAN

The issues I'm experiencing with this vehicle is delayed pedal response and a whole slew of transmission problems. There are no codes or check engine lights on. When coming to a stop and the vehicle downshifts you can visibly see the RPMs go up with each down shift and sometimes the downshift is so harsh going to 1st gear that it feels like another vehicle has bumped me from behind causing the truck to jerk forward and make a clunking sound. There is also a problem when upshifting where the RPMs will jump up before shifting into the next gear. I had a situation where I was turning left on a green light with traffic coming and had plenty of time to make it but when I rolled out into the intersection and hit the gas nothing happened for over 2 seconds. The RPMs didn't move and when I pressed the gas harder the vehicle went into a low gear and the RPMs shot up to about 5000 RPMs and accelerated rapidly to just miss an incoming vehicle. Vehicle has inconsistent shifting where it shifts ok one day and other days it acts erratically. I have been to two different dealerships and both say the truck drives as designed. I have had all the software updates done on this truck that were supposed to correct these issues but they have not helped. I opened up a case with Nissan support and they admitted these transmission problems were being addressed by their engineering team and a new software update would be available some point in the future, this was a year ago.
