Hi, I changed the 12v battery and now i get the service vehicle soon powertraim malfunction/reduced power and high voltage battery warning.

I read some threads on here about reseting the bms and i did that. I read about this same issue others have had. Ive plugged in to charge and it is charging fine. I took it for a spin and it seems ok.
I read someone can help by checking the VIN? Any other help available?

Thank you.

When my 12-volt battery needs to be changed, I think I'm going to take the car to the dealership...

Do these warnings go away after letting the car sit off for 15+ minutes? If so they are just a glitch.

If they are still there, you can try disconnecting the negative battery cable for 15 minutes.

If you had trouble putting the battery terminal on quickly, the intermittent connection and fluctuating 12V power can cause modules to fault.

When I install the negative battery cable, I try to drop it down quickly and hold it/press down while I’m tightening it so it doesn’t lose the connection a bunch of times and make the modules angry.
