So, I'm about to get on the highway after work to head home and in succession 3 system failures flash on the screen, and tell me to contact the dealership.

1) ACC
2) lane departure
3) mitigation braking

Little over 8000 miles on the car and this is just another thing to happen. I love the car, but I honestly wait for the other shoe to drop in between my visits to the dealership.

To date:
Lift gate motor replaced.
Squealing brakes which they replaced, it started squealing again after a week or so but I'm living with it.
Frozen infotainment system.

Best car I've ever owned but also the worst car I've ever owned.

 

I guess us people who buy the first year of a new generation are beta testers in a way.

 

Weird thing, I'm driving into work and all of a sudden everything went back to normal.

I guess I'll mention it next time I get an oil change or something, unless it happens again.

 

Sounds like a BCM issue or low voltage.

I got the same three warnings as you on a recent slushy day. Eventually the Radar Obstructed warning also came up.

After clearing off the Acura emblem, all four warnings went away after a few minutes of driving. However, ACC/LKAS/CMBS all use a camera behind the rearview mirror - so I guess that had gotten obscured as well - although I did not explicitly try to clean that area. It was a bad driving day, with lots of windshield washing required. EDIT: I think ACC/CMBS use both the camera and radar.
