HUD Shaking

[Callum]

Interesting, I'll look through KGIS and see what's what in there. Might be the position I have the step motor set in that makes it shake. I sit really slow in the car and the HUD is probably much higher than most.

There are a series of mirrors in the HUD system, above the actual projector. I am betting mine are loose. Service said the unit is really tight, not moving. I'm guessing I can pop off the trim panel and the top plate and see what might be shifting around.

HUD unit in it's glory...Looks like removing the trim plate doesn't remove the top glass unit. I'm not tearing into my dash, but going to make sure that glass lens isn't loose and shifting.

Per the service manual the adjustment function uses a step motor in the HUD unit

Aha! Thank you.

Then I would bet $1 that a MINOR adjustment of the HUD display height would remove the vibration. What I guess is happening is that there is a little slack in the gear drive and if you're not "seated" nicely on a gear tooth, it might be able to wobble a little.

Interesting thought, I will "bump" it down a bit and see if I can get the slack out of the gears. If that doesn't work, I can peg it all the way up or down and see if that helps

To test, mine is at max height.

Drive through a significant construction zone back road...

Not an ounce of movement.

The is for confirming. I will move mine up tomorrow and test.

Thanks for everybody’s help!

This evening I made a point to not avoid a few known bad spots and also pay particular attention when I passed over railroad tracks near my house - no movement at all.

Well, don’t change the height lol. I think me messing with all the adjustments may of created this.

I actually adjusted mine the other day, after adjusting my seat, after realizing I was sitting with my left foot on the floor and not really using the whatever-pedal is there in the corner.. didn't seem to break anything..

Mine rattles quite a bit as well. I’m going to end up taking it to the dealer because I also have the tailgate rattle and it’s a lease.

 

[Callum]

Moved the HUD in every single position about 5 times. Up Down, Rotate, etc. Seems to have removed 90% of the vibration. I'm guessing the last time I adjusted that step motor I hit the one gear mesh that had a little extra slack.

 

[Berzerker]

Nope, there's no chance that's normal. Mine has never moved.

Mine does over very rough pavement, and has in every car that I've owned that has had a HUD. It's definitely normal if the car vibrates enough since it has a non-gimbled motor that can adjust its direction.

Left lane, 400-S just south of Lenox road going under the MARTA bridge where the pavement is worn out makes my HUD dance like crazy. If your down in that area, let me know. Would love to meet up and drive that back to back and see

Edit: Right here

Google Maps

Yup. The get onto 400 from Sidney Marcus or Lenox going North is also really bad.

Yep, turns out I regret saying it wasn't normal lol. I've watched mine closely over rough pavement and it does vibrate ever so slightly. You guys ruined it for me

Glad to hear yours does it in the same spot. Honk if you see me. I'm usually in the heard of cars heading southbound in the AM's lol

Luckily I'm going to the other way up towards Alpharetta, I'll give you a honk if I see you though.

If you see a black GT2 heading in the opposite direction in the morning, I'll honk back. Know that stretch of pavement well and noticed the same issue after getting mine back from the dealer the other day. Will try to adjust height as well!

Nice! Mine should be pretty obvious, the rear end of my Stinger is carbon fiber.
