My S75 RWD does not have any shudder when floored, but my X75D has the shudder. As a result, the dual motor car can't really achieve its full potential despite having faster 0-60mph time than the RWD car.

Do you have shudder on hard acceleration? AKA death rattle?

I had this exact thing on my 85D (non performance). First time I talked to them about it they said it's wear & tear and would not be covered. The second time it somehow went through and they fixed it - the ride was super smooth since
on the MX thread, someone posted that there's a new service bulletin to fix the dreaded shudder. Can anyone confirm that there's one for the MS?

This is exactly the behavior on my 2017 S75D. I've complained multiple times to Raleigh SC and they refuse to replace the half shafts since "a fix is coming". Such horse sh!t.

I have my car in for this very issue right now
I was told there is a new service bulletin out specific to Model S. All they mentioned or me was a new bearing available in September
I was just given an update today and am now told they will have the parts need on Monday
So we’ll see
I had the shudder in my P85D, and brought it to the service center sometime last year to get it looked at. At that time, they told me it was normal and to expect some shudder when accelerating fast. It noticeably happened more when I wasn’t in low suspension.
But a few months ago, after getting Arachnid wheels put on, it started happening more frequently - even in low suspension. This time, when I brought it back to the service center, they agreed it wasn’t normal, and replaced both front half shafts.
I haven’t experienced any shudder since then. My car actually feels tighter when accelerating after the replacements. I’m hoping this is a permanent fix, but only time will tell.

I have a 2019 Raven with 9k miles and am experiencing the shudder under heavy acceleration under any suspension setting. I noticed it just after my Model S received an update with a 3% performance increase. I have scheduled an appointment with service center in a couple of weeks. Based only my forum and you tube sleuthing I'm expecting to get the two half shaft treatment unless there is a "real-fix" for this issue available.
2017 P100D here with the Unplugged lowering kit, not sure if that has helped but I don't have these horrible noises.
I was not aware there was any issues until reading about it on here but now that I am aware of it when in Ludicrous mode I always check the suspension settings before taking off hard.

Can someone help better explain the sound you hear when this happens?
for the first time ever the other day with my p100D Raven my car made a noise like a clicking at around the 50-60 mph range when I pinned it starting from a slow speed and almost seemed like my acceleration was a little throttle down as a result. It felt like a sound in the rear and almost like something was grinding/chattering. The car was cold at the time and had limited regen breaking but probably like 50%. The car was not that cold and did warm up some. Didn’t happen the following two days since I tested again.

Why would they be part of the "motor warranty"? Half shafts aren't a part of the drive unit, which is what that warranty covers along with the battery pack.

My 75D when cold shutters a bit in the rear under hard accel. Later as it warms a bit, nothing, hard and fast.
I would think the half shafts though are part of the "drivetrain" that is warranted for 8 years. Is it just the "drive unit" they are warranting here?
