Lane Assist Inoperative and loss of power

Tonight I was driving home and my Lane Assist Inoperative warning light came and I lost almost all power in the gas pedal. I could almost put it to the floor and it would go about 5mph. I pulled over, turned the car off and back on and there was no issue and drove home fine. I'm afraid this might home so was thinking to take it in to get it checked out. Anyone thoughts on this? Thanks!

What is yellow light on left dial - looks like stability error?

But heck this could be anything... worth having it checked out for fear it happens again.
hopefully it saved an error code

Sounds like it went into limp mode. As suggested, have it checked for codes.

I have lane keep assist inoperative and assist auto high beam inoperative error messages that show up intermittently (both always happen at the same time). Both will usually disappear after a few hour or the next day. Yesterday I went to the dealer while the error messages were on dash. They found out it's the camera behind the rear view mirror gone bad. Had to go back to dealer once the part arrive from Germany. Another user in forum said he had corroded wire connection on the camera. You might want to have dealer/mechanic check on it and your limp mode.
