Cruise control issues - completely shuts down head unit

Hi,

So just got back from a 1400 mile trip. During the trip the cruise control would fail multiple times, it seemed to happen almost every time I'd tap the breaks to slow down or disengage the cruise control. Multiple times that also made it restart the entire entertainment screen.

I did just get new tires put on, but they are the exact size as before, which did not present these issues. Has anyone else encountered this or know how to troubleshoot?

 

What year is your tundra? I have seen 2014-2018 infotainment units freezing up and restarting while driving when using the navigation system. Too much going on and it freezes.

 

Make sure your headunit firmware is updated...
