I have a very similar issue. It seems to happen when the temps are below freezing (which they have been for a month). Let me know if you figure it out. I'll be bringing mine to the dealership also.
About to pull the trigger on a Mudbath TRD Pro. I was wondering what exactly the “badges” stated below are? I assume the Heritage grill one is just an overlay for the TOYOTA on the front grill but I’m not sure about the other one.
