Software problems of the 2016 Hyundai Tucson

I have owned a 2016 Hyundai Tucson for 2. 5 years. In that time it has been in for several issues that can not be duplicated when at the service center and deemed "working fine, no codes present at this time". My issues have included loss of transmission control after a stop (software update fixed), intermittent headlamp that won't turn on, the media displaying "battery discharge warning" while car was running and in motion (headlamp replaced after several times taking to the dealership and I was lucky enough to have the warning light go on while the technician was there). Now the computer/dash board is restarting itself at 45 mph . This has occurred two times. The dash board went dark for 1 second and then started back up through is startup sequence. During this time, the engine is still running but I have no control over the transmission. If you push on the gas pedal it will increase rpms but not accelerate. During this time it is necessary to pull over and turn the car off and then back on. Again, no codes thrown and not reproducible at the service center. The service center found that the positive battery terminal was not completely tight and thought maybe this caused the issue. I am frustrated that something that could happen easily as this doesn't show up as an error since it caused a unsafe driving environment. 24 hours ago, while trying to make a left hand turn at a busy street the car started forward when gas pedal pressed but then stopped moving forward only to lurch forward after a second and pick up speed. I know that if I take it in for this it will be the same story: "we found nothing wrong. No codes thrown, bring it back if it happens again. " this car is not safe to drive and the manufacture will not buy it back since there was no defect found. . .
