Only the drivers door opens with touch, and the start/stop function has the circle with the line thru it. And it goes in deep sleep mode frequently. I drive it every day it’s not like it sits for days at a time. Dealer said battery was good at last service, but it sure sounds like it’s a battery issue. Any thoughts?

How old is your battery? 3 years or more and I would just replace it. Iirc there were some early software updated for that too.

Just had mine tested 6 months later after my last oil change. Said good battery per the tech. Yet I’m getting deep sleep messages, handles not responding, etc. I know it’s just a failing battery but they won’t replace until your dead on the road or it fails that test. It’s annoying. I know this is an issue because I do such short trip driving.

Back on the battery tender she goes.

I'm not a mechanic but I've found that when I drive somewhere to get the battery tested, it puts just enough charge on it to give a satisfactory reading. I don't know if that's what's happening but just a thought. I agree with Cruising68. Just get a new one. And it looks like a real P.I.T.A. to change

Takes about 2 minutes longer than a normal underhood battery.

I don’t understand waiting until a complete failure when you know you have a problem. Batteries are cheap and easy to swap…I’d much rather pay out of pocket than get stranded at some inopportune time.

That is true. But I have a portable jump starter in the car. So even if dead, I’ll jump and be on my way. I haven’t had any issues with the car running. If that starts happening, I’ll just swap it out. But I’m sorry, I shouldn’t have to replace the battery of a less than 2 year old car.

What people shouldn’t have to do and what they wind up doing are often times the same thing.
It’s a battery…sometimes they only last for a couple of years.

I know but clearly the battery is a weak point in this car. So many people get it replaced under warranty. I think it’s just such a power hungry car. Maybe I need to start including more prolonged spirited trips during my week. Charge that battery up some more lol

Or just stick a battery charger on it one night a week to make sure it stays charged.

that’s what I’ve been doing once every few months. Might just make a monthly thing at this point. Simple enough to do.

If your vehicle is left outside in the winter and it gets cold where you live, a discharged battery will be damaged every time it freezes. I think newer vehicles have such a high electrical draw during normal use that every start drains the battery down and unless you drive a significant amount each trip it will eventually be fully discharged. If you allow auto start/stop to operate as well, then you may stop and start the vehicle several times each trip which will compound the problem. Either drive it or charge it regularly.
