I have my Model X in the Vegas Shop right now, let's see if they can figure it out this time. They said they are going to talk with Tesla engineering. They have had to fix quite a few X's lately with the shudder.

No dice,
They said they flagged my car and will let me know when they come up with a real fix.
This is what my invoice says:
Concern: Customer: states vibration on hard acceleration. Please check and advise.
Pay Type: Warranty
Corrections: Perform Validation Test Drive
Road force values for old to be excessive which can increase the frequency of the
vibration. Verified new front tires road force values to be under 24lbs of road force.
Reviewed service history and found repairs to be performed June 30th, 2017 at
15926miles. Current mileage of the vehicle is 26487miles. There are currently no viable
updates to mitigate the concern of vibrations at 30-40mph during hard acceleration. The
Service Engineering team is currently reviewing possible solutions to correct the issue.

Mine got this issue after a few months too (Dec 2016 build). At the service center they replaced half shafts. This made it much less intense, but still there. I think it is getting worse again.
I noticed it only shudders on the first hard acceleration of a drive. Subsequent accelerations less so. Have others experienced this? Mine is X90D.
Has anyone escalated this issue and heard back from "executive team"?

Also. I live in Eastern Canada where there are Very Few MX.
I am trying to figure out if only people on this list experience this issue, or if it is widespread.
So for those of you with this issue in California, when you walk over to your neighbors house and try their MX, does it have the issue and they just don't notice or complain?

I had a service loaner MX75D with this shudder as well. I didn't think it was normal. Only happened with very "spirited" acceleration.

I'm sure the speed of repair varies from one shop to the next, but can anyone mention how long they spend in the shop with this issue? We're just getting worn down going back & forth.

I only takes them a day if they have the parts, they didn't bother to even fix mine the last time.
I have had half shafts replaced twice. first Aug 2016, second Aug 2017. seems to be good for a couple weeks then shudder returns. current mileage 31K. shutter not bad; maybe try again in Aug 2018.

TWICE !?!?
That's crazy! Here we were thinking we'd go in - have it replacee & be done w/ it.
(sigh) crossing fingers.

Just normal driving or have you done any towing? I think Tesla needs to find a new half shaft manufacture or get them to to upgrade the materials.
Ditto, though only at 9K miles. It's pretty horrible and makes moderate-fast acceleration unenjoyable. Normal driving, no towing.
I can't wait to see someone post slow motion video of the shudder occurring... the changing air suspension seems to be part correct? I can get a little of this on my model x while changing suspension levels and acccelerating hard with wheel slightly turned. It seems to be to be a non-serious side-effect of having so much power quickly transmitted to the wheels.... rather than a defect so to speak. It would be nice to fix though for sure. Would love to hear someone's best theory on what parts are actually vibrating... if suspension is lowering one side at a time or if it is slight wheel unbalancing that occurs. More than any other car I've owned, a wheel issue transmits vibration into the cabin. My thought it has something to do with changing yaw, or lack of dampening that occurs with all the weight at the bottom of the vehicle.
You mean hard accelerating out of a corner? I agree but I only feel it if I'm hard accelerating coming out of a turned stopped position degree, like turning from a stop sign and accelerating hard.
