I just returned from the dealer. I notice my headlights shake or flicker on bumpy (dirt) roads or when I hit a pot hole. Before bringing it in I asked if this was a common complaint and they said no. Of course when I took the time to take it in, they said everything was tight and it was normal. Has anyone else noticed this with factory HID headlights?

Yes, we have a 2008 Nav and it does the same thing. I haven't gone in and tried to tighten the lights up as I just keep forgetting (it's the wife's truck and I just don't drive it much).

Have you tried tightening up the adjusters?

 

Just had the dealer do it. They checked both and said everything was tight. I have read some other complaints about it on other sites. I guess you just have to "get used to it". Some people complain about the left side, some on the right. My complaint is in the right. I wonder if the bulb is just weak and as soon as it goes, a new one may fix the issue.
