I have a 2018 G80 Sport that I purchased used recently with 8,000 miles. I had sat for about a year before the person traded it.
The battery had had a problem holding a charge. When working, odd things happen on and off when I start the car - the drivers seat does not return to the programed position, the rear sunshade pops up (in the garage) or the Bluetooth forgets my phone to name a few.
I have had the battery tested twice, and it tests fine. Anyone else had similar issues?
