In owners' own words
My light control module has been determined by the local dealer to be defective. I've been told it is on back order w/ no eta. I've since been told the nhtsa has inexplicably found this to "not be a safety issue". I'm wondering on what planet the nhtsa drives that having intermittently working headlights is not a safety issue? I am expecting a more definitive and timely response to having my car repaired.
