“This has been going on for three years since 2011 at night at random times our low beam headlights go out on us as your driving down the highway. They may come back on before you get home but we have drove 1hr 30 minutes and still not. We did take it in several times and they can not fine a problem. They said they can change this n that senor but couldn't say that would even fix it. But cost us $$$$$$ why can't some one fine out do a recall we hate driving on our highbeam and so does the people we pass or get behind. …”
