I had a similar problem on my 2013 of the stop-start function stopped working, and replacement battery by the dealer fixed the problem, stop-start now working fine.
Sorry, I don't know about the collision warning not working, never had this problem myself, mine is working fine. Good luck with this, maybe someone else can help you.
