Transmission Solenoid problems of the 2016 Hyundai Sonata

Car shakes erratically when trying to accelerate and has no power after hitting accelerator. It struggles to get any power to get going after being stopped at a red light. Gear changes get stuck and I have literally been stuck in middle of intersection while doing a legal u-turn in a busy busy la intersection with my 10yr old in the back seat and the only way to get out of the situation was to turn car off and turn on again which poses a major safety issue for both my daughter and myself. Took car in to service last week and they supposedly fixed issue but one week later here we are with same problem. Service told me it looks like solenoid is going out. Which seems strange for a 2016 car with only 27,000. So if this was the case why not change it before it was sold to me. Also car had prior issues before it was sold to me according to service. I smell recall???? I have no documentation but the dealer has all supporting paperwork.

When depressing the brake my car is making a clicking noise. Went to the dealer and he said it is normal. Previously it was little but now days it is making loud noise while driving. When we depress the brake and try to change the gear from p to d the gear rod is making same clicking noise. When read forums I heard that it is the problem with the solenoid but the dealer does not want to do because he has to do it for free. When asked the dealer he said that it does not come under warranty. Now the noise is really loud and no one is helping me out.
