 I purchased a 2016 Tucson in April .  this was my all time favorite car, until last week.  I drive on the interstate every day and often experience heavy traffic.  this day was no exception.  I was in stop and go traffic.  it was about 90 degrees outside.  I took my foot off of the brake and stepped on the accelerator and the car would not go.  there were no indicator lights on.  I put the car in park and retried and the car would not go.  I was in a traffic jam so I put on flashers, called the Hyundai motor assistance and began the wait.  the car continued to run not overheating no indicator lights.  finally some concerned motorists came to my rescue and pushed me off of the highway, because by this time I was causing a traffic jam.  while on the side of the road, the transmission overtemp alarm indicator came on.  this was more than an hour after the problem began.  I shut down the car.  AAA came and he started my car and it was fine.  I felt like an idiot.  I figured that the dealership would say that I was making it up or that women don't know how to drive.  I was on the highway stranded for 3hours and by the way the road side assistance never showed up.  they called 5 hours later at my home to ask if I was safe.  my car is still at the dealership.  they do not have a fix and the service manager was very nice and honest.  the big problem for me is that this car is not safe and Hyundai is in denial.  I'm going to the tv networks as this looks like it fits the criteria of a lemon.
