Pls keep us updated thanks
I apologize, can you please clarify what shudder is being referred to here? My Model S shudders when I accelerate slightly aggressively from a low speed or from zero. And it shudders when I use the brakes to come to a stop. Is that the type of shudder your X experienced that your post refers to?
Thanks you for your attention to this.
MXs tend to shudder under hard acceleration when suspension is set to high. But as time passes, it starts to shudder even on regular height. It only occurs under hard acceleration (flooring the accelerator). I DOES NOT shudder when braking or slowing down, however. So your issue is likely different.
My service center in Palm Springs a few days ago when I was discussing this with them they said he had heard they were working on a new motor mount to fix the problem. Looking forward to seeing the part number for this.
The Model S has a similar issue. Any indication if they have a fix for the Model S as well?
We have both an S (early 2017) and an X (early 2018) and I can confirm that both of them shudder under hard acceleration, even at Standard height. I agree with what someone else in this thread said that your shuddering under breaking sounds like a different issue from what is being discussed in this thread.
I would be curious to see if this fix is also for the S as my SC in Richmond, VA told me over a month ago that they expected to have something by this Summer.
Just stopped by my SC in Portland and showed them the post of the new part numbers. They called the parts guy over to take a look at the new part numbers. I was told those are the old numbers but there is a D revision that has just come out and is hard to get. Asked my service center to get the D version of the parts needed to fix the shudder. I am hoping this is the permanent fix for half shafts. Asked if half shafts would be included in the motor and battery warranty and was told because this failed before your 50k warranty that it would be covered under motor and battery warranty
New motor mounts and D revision parts.
The plot thickens...I hope this saga has a satisfying ending.
Perhaps the motor mount is the key part, as the other parts in my work order look standard. There was no point for my SC (as they told me themselves) to replace these with the previous flawed shaft system. Would be a waste of money and time.
And typically in the 30 to 40mph range. I think for many people, the accelerator does not have to be “floored”, but brisk acceleration is generally needed to detect the shudder.
Thanks for the update on the Portland SC. Really appreciate you mentioning it here. Seems educating the SC is a duty us owners have to take on.
Maybe this time we are out of the /shudder/ spin cycle? I'm at 41k... and watching the odo tick towards 50k.
Looking for any updates you can share regarding the new part, etc.
I just submitted a service request (in 3 weeks) to get my shudder fixed with these new parts. Will update all if this is indeed a fix.
I shudder to think what this will cost out of warranty.
My confidence that it will be affordable has been set to “very low”.
Made an appointment for 13th to do the motor mount and other fixes for FWD.
If it started shuddering while under warranty, and Tesla was unable to fix it, it would still be covered under warranty even if the car is now out of warranty. You might need to threaten them a bit but warranty law is clear on this point.
If your car is shuddering when you brake, then you likely have one or more warped brake rotors. Those can be “turned” (lathed) or replaced and that problem will go away.
If your car shudders at a constant speed it could be an out of balance tire or defective tire.
An update on the new fix. I tested acceleration at Very High & High suspension settings, and no shudder. Before, even when the car was new, it shuddered at those heights.
I remember when I first the got the halfshaft replaced the first couple of months was fine and then shudder started again. I'm hoping your fix is permanent!
I agree...Honeymoon period...hope @polymathic got a permanent fix, please report back @polymathic if it recurs.
