I just started getting a "PKSB Malfunction" message on my 2019 Prius AWD multifunction display. I took it into the dealer, and they indicated that the front right sensor had been damaged by some sort of road debris. They want 8 hour of shop time, plus parts to fix this. I would like to disable the parking assist function, since I am proud of my parking skills, and doubt I will ever use this function. I don't believe it is worth $1200 to fix this. Can anyone point me in the correct direction? The dealer was obviously no help.
