Riding home Monday at 70 MPH screen turned orange and said brake failure. Pulled off road and shut down brakes seemed to work fine stopping. Turned key off and removed it. Sat for a few minutes then started back up and screen returned. Put it in gear and it felt like the brakes were locked up. Shut it off again and then restarted screen returned but when I put it in gear it moved without resistance. Drove home. Next morning started up and no screen. When on side of road I pulled codes and got C1048 or it may have been c1038. either way next morning it was gone. Loaded it on trailer and returned it to dealer. They will not look at it until Friday and then have to submit to BRP which they say will take a couple of weeks. I only have 2988 miles on this 2015 RT limited. Any ideas as to what might be going on. I am afraid to drive it until I have some explanation for Brake failure warning. Thanks in advance.
