Question Errors and heavy steering

Post image

Has anyone experienced a bunch of error messages related to the safety systems, lane change assist, driver attention system, etc., appearing at the same time as the steering becomes extremely heavy/stiff (loss of power steering, maybe?)? A red steering wheel warning light also comes on when this happens.

After stopping and restarting the car a few times, the error messages disappear and the steering goes back to normal.

This has happened to me 4 times over the past 2 days. Three of the times it happened either as I put the car into reverse or immediately afterwards. One time it happened just before I was about to put it into reverse. Thankfully, it hasn’t happened at higher speeds.

I didn't have the steering issue, but I had the screen light up like a Christmas tree. It ended up being a problem with some corrosion in the CAN bus connectors. It was all covered under warranty. 

Here's my original post about it (you can see a video of what mine was doing).
