What have you done to your CX-50 today?

Seems to. You may want to get the dealer to email you the battery replacement instructions for your specific accessory just to be 100% sure. The one I found is for a CX5 one but I suspect it's the same but you never know!
I had to pop the first one off minutes after installing it because I put the battery in wrong :rolleyes:
Pushing in the middle and pulling on the edge worked. I was worried I might pull the new tape off but no issues.

Ahh, very interesting. I see they just do a fake button press at startup. I might try a DIY version for grins :)

See these DIY versions. These show how it works... the I-stop button is just part of a resistor ladder along with the other buttons. The workaround to disable the i-stop is just to use a relay to quickly bridge the two common wires with a suitable resistance (~85 ohms) right after the car starts. I like the method in the second link that stores the last state so you can enable or disable the I-stop when you like. I have done many projects with these microcontrollers, so wouldn't be hard for me to do (now I know how the button works).


I should point out that a DIY setup would not save much money over the pre-built one you show - it's more for grins and accomplishment than anything else. Really appreciate you bringing this to my attention!

I can see if the start stop function is separated by itself would seem doable like my acura tlx but since our cx50 has multiple functions on the same connector makes it a little difficult and just not worth the time like you said unless you like the challenge and you know how these things work good luck.👍🏻

I'm curious, considering the i-Stop is combustion based restarting instead of battery based (like everyone else for the most part). Why do you have a desire to permanently disable it?
I think that the "combustion based" method doesn't always work, and the turbo cars certainly have a larger battery to account for that. But I don't believe the battery is the point anyway. I personally would certainly be wary of additional wear and tear on the engine from constant restarts, especially after oil drainage when stopped.
