I joined to troubleshoot my OEM HID headlights. It's a fully loaded (and I mean fully) 2015 300C platinum phantom black. Really really slick car. It has 85000 miles (i go everywhere). Anyhow, I decided to check the fuses even though the dealer said that I may need to replace two parts; one costing around $600.00 and the other costing around $1600.00. Low and behold both HID headlamp fuses were blown with same terminal burned on each fuse. I replaced the fuses, all good so far (it's only been 15 minutes). Anyhow, I'm posting this information just in case someone else has the same issue.
