Issue with all Collision Assist

[demens]

Hello everyone,

I am experiencing an issue where all of my safety features have just shut off and nothing will work. If allowed, I will include a picture of my cluster for reference, but cruise control does not work, auto hold does not work... the only thing that does work is lane keep and it freaks out a lot.

Random side note is that I can no longer use the camera moving forward... only in reverse....

Any thoughts?

My car is a 2020 GT 2

bad speed sensor should still be under warranty with that mileage and model year

All of those features use the front camera and the forward radar unit, sounds like one of them isnt functioning properly.
Have you had any front impact or had your front bumper cover off for any reason?
The rectangular plastic piece in the grill houses both units...is that damaged?

I've gotten that sporadically (like 4 times since I bought her about a year ago). I shut it down, turn it back on, and in about 5 minutes or less it all goes away. Couldn't pull a trouble code or anything.

Since I installed my snorkels, I hit all of the front end connectors with some contact cleaner and re-seated them and haven't had it happen since.

This is what the dealership said; I am there now waiting for the official diagnosis, but they said it was most likely that.

My front camera took a rock in the first 1000 miles of ownership... didn't care enough to replace it, but can confirm it did not alter anything in the way of how the car worked, drove, or how the safety systems operated. Only thing the rock did was cause the front camera to have a black line across 75% of it.

The forward radar unit is fine, though, and the front bumper cover has not come off.

the ABS light and auto-hold error lights are the tip off that it's a speed sensor. Happened on our 2017 santa fe, the dash lit up like a christmas tree with the same errors including forward collision. One wheel sensor later, no more errors.
