NHTSA Complaint #11567726 — 2016 HYUNDAI VELOSTER

I have done a lot of research on my car when it started having issues with major oil burning/consumption (I took it in because I had an engine recall and they did their testing and said no recall for my car). And since 2021, I haven't had a consistent working heater and a/c because a wiring issue. Which I have spoke to hyundai on a few occasions and told me "you just need a new hvac control head unit" which I had already replaced. The harness connector was fried, had that replaced by someone I know. May be not to standards, but it would usually work with most vehicles. I have replaced the head unit 3 times now, and the wiring harness 3 times. And it eventually fries the knob control for my blower speed. I have an 16 month old child and its a safety issue. The wires keep frying (my resistor has been replaced a few times thinking that was the issue), telling me the wires are not capable of the output for something so simple. In my research, this has happened to thousands of other velosters around the year of mine. And one was a mechanic and said it is a safety issue. It can catch on fire, and this should be a recall on all cars. I've also read how hyundai has told people with recalls, their cars were fine (after testing) then the engine blows and they're incompetent and so not care to help its consumers. Please help me somehow?
