first occurrence happened a year and a half ago. dealership fixes the issue free of charge, warns me that if it happens again they will need to replace the headlight assembly.
fast turn signal came up again a few days ago, dealership tells me they have to swap out the headlight assembly which costs $500+, not covered under extended warranty. contacted SoA, they're looking into it and will get back to me.
