Welcome to the forum. Tire noise: C-Max is so quiet you hear/notice noises you don't usually do on ICE vehicles. They should quieten down as they settle in or you get use to the noise, Inconsistent warning lights, rear hatch: possible weak 12v battery or weak battery in key fob. As an owner of a 2013, it's NOT maroon, it's called Ruby Red. Sounds more regal & expensive, don't you think?
