Hyundai Tucson 2015: Why am I having so many issues?

I purchased a new Hyundai Tucson Active X in May 2016. It was advertised as a 2016 model, but I later found out after the purchase that it was a December 2015 model but anyway … it has always been serviced by Hyundai at the exact km intervals when due. At the start of this year the engine had to be replaced as it started making a clicking noise while I was driving it to a Christmas function one day. The Hyundai dealership I have always taken it to replaced the engine. I have also had a fault with the left blinker not always going on or staying on when switched on, which has been mentioned to them multiple times, but still always plays up every time I pick up my car and I have to mention it to them again. Now yesterday, when I was driving, my reversing camera got stuck on my screen and wouldn’t go off even when changed to park/neutral/drive etc. I tried turning my car off and leaving it for a minute and turning it back on but still no luck. As well as that, yesterday just after the reversing camera started playing up, the brakes started making a clicking noise from near the gears area when pressed when in park, but not at any other time.

What is going on with my car? I purchased a new car hoping that these sorts of things wouldn’t happen. Have I been sold a dud? I loved my car when I first had it, and planned to update in another year or so, giving my car to my husband and I would just get a new Hyundai. But unfortunately after these experiences so far, there is no way I would be buying a new Hyundai or recommending a Hyundai Tucson to anyone. What is going on with my car and why are there so many issues? Should I contact Hyundai head office?
