Well, my 16-year-old daughter mistook the gas pedal for the brake and slammed into a brick wall in our 2016. At first, everything seemed OK, but a few days later the pre-collision system unavailable message came up. I also believe the automatic cruise control will not work. If I’m not mistaken, the problem is with the sensor behind the Toyota emblem at the front. I assume replacement cost will be $600-1200. Is this something I could possibly change myself, even if I need to get someone else to recalibrate it? Is buying a used one a bad idea? Is it that sensitive that it should fail after being hit?
I'd search for one @ the wrecker/junkyard, side or rear impact car. IMHO Yes, cruise control won't work - car can't judge distance from car in front until this is repaired. Did you check for loose wires and connectors?
