At night -- (probably because that is when I can see it).. when I hit a bump I notice my headlight beam jumps all around... also I can move them a bit with my hands (up and down)

Is this normal?!?!?!?!?


T.I.A.,

When I first drove an 04 for a day and one night, I was disappointed to see that the 04's seem to have the same shaking headlamp syndrome as the last generation models, even though it's a totally new front end with new design headlamp assemblies. It seemed to be the right side one, just like on my current 2002 GT. And yes, I've seen numerous other new GP's with the same problem. I'm thinking the dealer will tell you "well, that's just how they are" or "that's normal." Very disappointing.....

They should've been working on it when the car was being designed...

Try lowering the hood latch, so that it closes tighter. Mine was too loose from the factory..it never hit the black rubber stoppers. Once I lowered the hood..nearly all the headlight bounce went away.

Where the hood sits should have nothing to do with how secure the headlamps are. You should be able to drive around with no hood and still have stable lights. If you adjust the hood, you might mess up the hood to fender gaps.

Mine bounce too. At least I can see at night. They're so much better than the 03's.

Hum...thinking ahead, my bounce but very slight. Is this a way to make the bulbs or the assemblies last longer? A little play to stop stress transfer?
I await to see what TallPaul come up with...

From what I hear GM already has a bracket, its an L shapped bracket that replaces the White Plastic piece. This goes in its place and gets secured so the lights do not move.
