2013 Model S 60
So yesterday I got into the car and saw a 12V battery low warning and thought, ok I am going to have to call service and schedule an appointment to replace the 12V battery after I get to work..... But turns out the battery is too discharged to even get the car moving. The main battery was fully charged to the daily limit 90ish%. I had no previous warning that the 12V battery was low and I had to be towed to the service center. Now that it is at the service center they want to replace the DC-DC High to Low Voltage converter ($2100 part $400 labor). The 12V battery is probably around 18 months old. Has anyone had to replace the DC-DC High to Low Voltage converter? On the one hand, I had no warning that the 12V battery was going dead, on the other hand it is 18 months old.
