So I'm driving to work this morning and suddenly I start getting constant warnings that ACC, LKAS, crash mitigation, lane assistance, and a couple others I believe were not working. The messages are constant so it seems they are going on and off or something. Vehicle seemed to drive normally but of course I couldn't use LKAS or ACC. It's a 2019. Is this a known issue and/or anyone familiar with a TSB or something? It's going in to the dealer on Thursday but now I'm concerned about driving it.

 

Did it happen while you were using ACC? If so, maybe apply TSB B19-051 first. The latest ECU firmware I saw for 2019 is Ax9, so newer than Ax8 mentioned in the TSB.

 

Do the faults persist or did they clear after you stopped and restarted the car? If so, it's a "glitch". If they persist, you can still drive the car. You don't need any of those systems to operate the vehicle. Turn them off and take it to the dealer.

 

Cameras and radar areas are all clean?
