My wife's SFS 2014 2.4L started exhibiting a "hard start". It started a few weeks ago and I thought it was because it was cold but on the cold days sometimes it would start up fine and some days I'd hold the push button for 3 - 4 seconds while it turn but not start. It's random, on a warm day one time it would start cold immediately and one time crank for 3-4 seconds. The battery is 3.5 years old but lights and everything work fine when the car is off. Anyone else have this "problem"? I'm fearful at some point my wife will be driving and it won't start while she's in the city or far away from home.
