For general info I've had my CX-50 Hybrid since the third week of July 2025. Tonight I got an error trying to start the car and felt it was probably the fob battery. I held the fob close to the start button and had no further problem. Got home from my errand and noticed the door didn't auto lock after I got out. I pulled the fob apart to check the battery level. Battery was a .7 of a volt. So I got about 9 months out of the battery. I don't use the power saving feature that is in the app. No real complaint other than I now have a timeframe when to check that battery and knowledge that when you get to about .7 of a volt, it's going to give you a problem. I'm curious to check my spare fob which is always at home. Curious to see the battery level in it. I'll post that once I get it checked.
