I own a Hyundai Tucson 2018…
I own a Hyundai Tucson 2018 and I, have only had to replace one engine sensor on top of the vehicles engine. I am currently at 71,000 miles and only two things get my attention the fuel pump or injectors may need cleaning after 50,000 miles or possible replacement. I use Lukas Oil Deep Fuel Cleaner not only to clean but also gain mileage after refueling. The Key FOB anti-security could plague you, if you do not change the FOBs battery every now and then. Could leave you stranded so carry a spare lithium battery. First clue Key FOB not detected especially after the first attempt to start but could get the 2nd attempt going. All vehicles seem to be good until they reach passed the 50k mile mark afterwards good luck.
