Inoperative and Active Brake Assist Functions Limited

[Z070305]

Hi everyone, I was driving my gla180 fine. After parking, I went home for dinner before coming back to start the engine about 20 minutes later.

Seconds after driving out, all the warning lights suddenly came on and the steering wheel became very heavy. 
 

I tried to find answers online, seems to be faulty sensor? Anyone has encountered similar issues? Please advise on how you resolved it and the possible cost. Thank you

Is there any obstruction to the camera on the windshield or the radar?  Could be as simple as smeared bird poop that will prevent the system from functioning normally.

I tried cleaning the window, grills etc to no avail. This morning, the problem persisted despite the overnight parking. After driving it for 10 minutes, I parked the car and let it rest for 10 minutes. When I restarted the engine, the issue was suddenly gone. All the warning lights went out except for the engine light.

If I recall correctly, the carpark ground was wet when I drove out the car from stationary position. It sorta skidded and the lights came on almost instantly after that.

What engine light? The orange check engine light??  You need to scan for codes to see what the error is man.  I don't think the brake assist is causing this.
