Just replaced our 2014 CX-5 with a 2015 CX-5 AWD. Problem occurred within first 100 miles. (5 times) On occasion it will not start, towed to dealer today, and of course it started there. Dealer had over last weekend, no problems. Happens sporadically, then after trying for a numerous times will start. Red light on key fob and brake pedal pushes hard. Dealer said they checked battery on Fob, brake relays, etc. They called Mazda, no help there, no stored codes. Anyone else experience this problem? Ready to give car back and get 2014 CX-5 back.
