Hi guys currently driving a 500c. Most days I got the s/s , hill assist and one other warning light comes on. I was told it maybe due to me not using the car enough to keep the battery topped up or it maybe the battery getting old. As I have no clue with cars and before I take it into a dealership which will rip me off I’m wondering does anyone have an idea as to the problem??

Welcome how old is the car? Has it ever had a new battery?
