    This is the second time I’ve had a large red square warning light pop up on my dash screen. It takes up almost the entire left side of the screen. Happened a while ago and I thought it was just a glitch but it just happened again. It says something but it turns off too quickly for me to read it.

    Of course I took my manual out of the car to read about the AC and can’t look it up. Just curious if anyone is familiar with this. Googling was NOT a good idea. : } It just flashes on and then disappears. Thanks

    Probably automatic emergency braking (AEB) or automatic parking braking.

    While I’m driving? I forgot to mention that detail.

    Yes, that red “BRAKE!!” warning would only come up while driving.

    Well there are no cars in front of me when it happens and no auto breaking occurring.

    It can still get confused or detect something you didn’t see.

    Doesn’t even have to be in front of you. Thinking garage walls, etc.
