Hey guys new to the forum. Really need some help. I have the Brake Warning light on in my 2018 Chrysler 300 touring RWD. This has been on a while. Message center says “fluid level low”. I have had it diagnosed twice and they could not find the problem. (Not at a Chrysler dealership, I work at a Honda dealership). The light stays on constant while driving or parked. Parking brake system checks out, brake fluid level is good, never leaks either, all pressure is fine and don’t lose pedal or mushy feeling. Sensor inside master cylinder is plugged in as well. One mechanic said maybe a body control module. Not sure on that though. Any insight on this?
