Transmission Slip Out Of Gear problems of the 2016 Hyundai Tucson

Related to original recall campaign - 16v628000. I had the updated transmission control software/recall installed in November of 2016. The update worked for a time, but performance has steadily declined once again (this software has been either updated or reset by Hyundai multiple times since purchase). I have been stuck at intersections with no acceleration, the ability to accelerate when merging onto freeways is limited (almost impossible to convince the car to shift to a lower gear), and shifting out of 1st gear at low speeds/local traffic is highly sporadic (sometimes it feels like the 'clutch' is half engaged; other times it won't shift out of first, so you accelerate faster than you want and at much higher rpm than would be considered normal driving). Hyundai has just reset the software in my car so that it can 'learn' again, but the update provided with the recall did not fix the problem. I would very much like something to be done as new car owners should not have to update software multiple times per year in order to have their vehicle operate safely.

Fails to fully engage gears, feel like transmission has slipped out of gear, won't always go into first gear when starting out. Or goes into first and second is not there, no power to move until foot is lifted off accelerator, wait a few seconds then try again.

In two separate incidents about a month apart, I was stopped at a traffic light behind several other cars. When the light changed and I pressed the accelerator, the engine revved, but the automatic transmission did not engage and the car would not go forward. It would go backward, but not forward. A warning light came on for a few minutes that said the transmission fluid was too hot and I should stop the car safely. (like it wasn't already utterly stopped, in the middle of a left-turn lane. ) after a few minutes, the warning light went off, but the car still would not go forward, first incident occurred after about 2,400 miles. The dealer said that Hyundai technical told him there was an update to the sensor software that would fix the problem. He said he performed the update. Second incident was about a month and 600 miles later. Different traffic light, different left turn lane, same problem. This time, as I waited 2 hours for a tow truck, after about 25 minutes, the car spontaneously dropped back into gear and I was able to drive it 2-3 blocks before it stopped dead again at another traffic light. In the remaining 90 minutes while I waited for the tow truck, the car would sporadically be able to lurch forward a few feet in low gear before dropping out of gear again and stopping. The tow truck driver who tried to drive the car up the truck ramp experienced the same problem and verified it. Car has been at the dealer now for over a week. Today, Hyundai technical gave it a "fast track" number. Service manager is still waiting for direction from Hyundai technical for what to do to fix it. He told me that my car is not the first car he has seen with this problem. And while my car has been in his shop this week, another vehicle has come in with the same problem.
