Cross traffic allert malfunction

[bsupra98]

My car is all of the sudden goving me a “cross traffic allert malfunction out of nowhere. Nothing is blocking the sensors or anything.
I don’t drive the car much, its a 2020 and Im pretty sure its the original battery. I’ve been told that these cars get wacky when the battery is gets old/weak. On bimmer link it says my battery is at 57%.
Idk what it normally sits at, should I replace it?

Yes replace

Or grab a CTEK charger and let it sit overnight?

BMW Batteries do last a little while. My 2015 435i is still on the original battery and it's got 90k miles.

All the above. BMW electronics will go nuts with bad batteries.

You might want to replace it, but if you do, you need to drive the car more often and for longer distances. Or get a charger, or both.

You could start with the charger and see if it brings the battery back to life. Then replace if not. Might need a load tester though.
