I bought my 2012 with 15,000 miles in May 2015. Everything was good for about a year, but in May 2015 I came out to a fully charged battery and the error message "Service High Voltage Charging System". Took it to the dealer who did the whole fill coolant and check the system thing, and then tried to charge me $180 (another story).
A week later, the same "Service High Voltage Charging System" error came on and the dealer then found a tiny leak in the battery coolant reservoir. They replaced that and refunded the disputed charge from the first visit.
A month later, the same "Service High Voltage Charging System" error came on and the dealer decided it was the charge port and replaced that.
A month later, the same "Service High Voltage Charging System" error came on and the dealer said they did some type of update to the system, but asked that I start bringing my charging cable with me.
This week, the same "Service High Voltage Charging System" error came on and it's currently sitting at the dealer waiting for service.
Each time this has happened, it's been after a night of full charging, the Guess-o-meter range looks normal, but the error message is on. The coolant doesn't look low any of these times (even the first time). It's also happening nearly exactly 1,000 miles apart (now at 25,000 miles). It's really getting frustrating, because I love everything else about the car, but the time at the dealership is starting to add up.
Does anyone have any suggestions? I did some searches on old postings, but most seem to be related to the known coolant level issues.
