2015 CX-5 Key Fob on occasion will not start car. Dealer is at a loss. Happened to
anyone else? Didn't start, towed in then started. Bad Key Fob? Eratic signal to sensor
at times? Can Key Fob work then stop, then work again?
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
Battery maybe getting low
Help both key fobs quit, 1 works occassionally, 1 not at all. When started with me brake was extremely had to push but car had been driven less than 12 hours previously. I have a hard time believing it's the batteries since both started acting up within 30 days. Any suggestions appreciated.
I have a 2015 cx-5. Mine is not working now. It has been getting worse over the last few months. I literally need to bang it on my steering wheel and mess with it for 10 minutes - 30minutes. Took it to my original dealer who is no longer Mazda, and they said the battery and the key fob were working fine. They told me I had to go to a certified Mazda Dealer in another town to get it looked at. It is so annoying! I have loved my car until this started happening.
Put your key on the dash , this has solved the starting. Problem
