Very few LED mods are truly plug and play with modern vehicles that utilize an LKM. Even our 2011 and 2013 Kia Optima SX's (also use light control modules) weren't happy with LED mods and required capacitors.

Edit: The only reason I have not converted is that I have yet to get INPA, DIS, etc working and to start working with coding.
