Adaptive Cruise Control problems of the 2019 Hyundai Kona

I have two Hyundai vehicles one is a 2018 tucson and a 2019 Kona. They both broke down at precisely the same time at 109,000 miles. One was the catalytic converter dealership was going to charge $5,000 for repair found a less expensive place to do it for $2,000. I was told by several of the mechanics at both places that it was a common problem. My point is I just paid the vehicle off it was just out of warranty then your stuck with it. Dealership just shrugged it off as maybe you should buy a new vehicle. The second vehicle Kona had some catalytic damage but not enough to replace the crankshaft positioning sensor failed caused the car to basically shut down on the roadway all of the adas systems failed. Again dealership was going to charge $2,000 found aftermarket place to do for $1,000. I'm sure nothing can be done for me but I feel it should be documented if people in the industry are telling me this is a familiar occurrence then maybe someone should look into it.
