1 Assist problem

Failure Date: 05/28/2021

Back up camera glitches. Causes driver assist to take control at times when not necessary. Have has this in for service at least 4 times since purchasing vehicle in 2020. Service states repaired each time bit eventually happens again. This last time is getting more severe cause multiple electrical short in overhead lights, panoramic roof failure to close at times and rear hatch sometimes only partially opens. I saw recent recall for 2021 and 2022 Santa Fe's, I believe this problem is what is happening with my 2020 Santa Fe and the scope of the recall should be expanded.

2 Assist problem

Failure Date: 10/27/2020

Hyundai 2020 Santa Fe limited blind spot collision-avoidance assist (bca) system when set in active mode and under these conditions its activation is extremely dangerous: in three (3) or more lanes of traffic. In neither of the outer lanes. Passing a truck in the lane on the immediate right. Vehicle(s) in the lane on the immediate left. Vehicle(s) in the lane on the immediate right. At speeds of 50 � 70+ mph. When the Santa Fe approaches the front end of the truck, the bow wave of air from the truck pushes the Santa Fe towards the left lane line activating the bca, which violently jerks the Santa Fe to the right. When this occurs and the Santa Fe is moved violently toward the right line lane, the bsa detects the truck (or other vehicles) in the right hand lane, and violently jerks the Santa Fe toward the left hand lane. Upon doing so the Santa Fe bsa again detects vehicles in the left hand lane and again immediately jerks the Santa Fe toward the right hand lane. This action continually occurs until the driver forcibly regains control of the steering wheel, and/or depresses the brake. This repeated violent jerking the Santa Fe back and forth across the lane it's in has very nearly caused an accident in at least two (2) occasions (oct 27 & 28, 2020) until we found that the bca could be deactivated and set to warning only. This violent action of the bca should be removed from the Santa Fe vehicle to prevent accidents.
