I had 1 1/4" hitch installed in 2018 Niro (I could have done it myself since there was no 'cut-out' of the rear panel) for a bike rack. Neither the rack nor one bike on the rack interfered with the rear sensors (I have all the safety features and sensors available). Since I am a snowbird and usually manage 2000-2500 miles and several days of travel (some always it seems at night) with 200-400 pounds of gear plus spouse and me, I am concerned about tipping the front end up due to rear end weight. I had inflatable airbags installed in the rear coils springs, as I did with my Prius v. I measure the height of the wheel wells before loading and then inflate the bags so the height is the same as unloaded. When not loaded I deflate to a low pressure but still feel a stabilizing influence when on a rough road or a road with dips.
