Partially Solved: For some reason after the car sits for an extended period of time the brake pedal becomes very difficult to push thus activating the switch. If one pushes on the pedal very hard it will activate the switch. When this happens it is like pushing on the brake pedal to stop when the car engine quits and the vacuum assist is off.We owned a 2014 CX 5 and this never happened. Dealer says it is normal.

I had the same fault with my cx5 2015 model I replaced the battery in the remote with a cheap and nasty one but still had the same fault I could open the doors with the remote but it couldn't start the car. so I went out and got a Lithium battery, it has been working fine for 4months now with out a problem. Give it a go it could be a quick and easy fix. As for the brake peddle going hard it sounds like a vacuum leak in the booster or the check valve is faulty, I can leave my cx5 for a week and still have a enough vacuum in the system. I think this dealer should be head slapped and told this is normal
