Hi, I'm sorry to hear this. Please let me know if you plan on visiting a dealership for this concern. I would be happy to open a case for you.So I'm still having issues with the brake lights on my 500e. Can't seem to find any that will light with the parking lights. Brake? Fine. Parking light - no go and bulb out error. As soon as I put in the incandescent, everything works just fine. I'm pretty close to giving up...
