Transmission Not Engage problems of the 2012 Hyundai Tucson

This is a complaint that mimics the current recall 16v628000 from Hyundai on 8/30/2016, for their 2016 Tucson transmission problems of the engine/transmission where it will disengage. When driving and pressing on accelerator the engine revs, but the transmission seems to be in neutral (even though in drive). It has happened to me on my 2012 after I made a gradual right hand turn around a ramp at about 25 mph . I had come out of the turn and tried to accelerate when nothing happened. The engine rev'd to about 4k, I immediately let off gas thinking I had bumped the gear shift into neutral or it had somehow popped out of gear. Nope. Light on dash still said "d" and the gear shifter was in the proper position. I let it coast for awhile and then tried accelerating again. This time it worked fine. I have only had the vehicle for about 2 weeks and did not experience any issues before this. I was a auto/diesel mechanic for over 14 years and was very cognizant of what was happening, not panic stricken. If I get a case number or the like I will continue to follow up with you on the issue. No engine lights came on, engine did not stall, no codes generated on obdii scanner. (2 cycles of on/off before checking for codes when I got home) tried checking the transmission fluid level, but it is a sealed unit with no dip stick.
