Shudder / Vibration

[TBrownTX]

I experienced a shudder at highway speeds while taking out my new '24 MSLR. After a brief search, I found a vast shudder and vibration thread, but mine differs from what's spelled out there. If there's another thread, I won't be insulted if you share it.

What I'm getting is a shudder at full throttle over 50MPH, nothing at all at lower speeds or under partial acceleration. I had read something about the different suspension heights and wheel sizes. I was running a medium setting with 21" arachnids. I set the suspension to low, and aside from what I think was the sound of the tires screaming under the torque, it seemed to disappear.

Is this pretty common with these cars? I assume it's OK to drive around in low; I don't have a need for a higher ride height due to parking garages, a set driveway, etc. and frankly it looks even better low anyway.

My 2020 LR first started with shudder like you have now, hard acceleration at speed. It later expanded to shudder under acceleration of most any type. New half-axles in the front fixed this. I am amazed that apparently they are still using the same half axles after all these years, because it is a fairly common problem.

The car will go into low at highway speed regardless of your settings.

2020 doesn’t have the same suspension or half shafts as the refresh. Although the general description of vibration may apply to both, the actual causes are different and shouldn’t be generalized.

There is a service bulletin about this for 2017-2019, so they had the problem. Mine is a 2020, I assumed Tesla revised the half shafts for the service bulletin repairs and put those on mine. Now this is a new 2024 exhibiting the same symptoms. Maybe Tesla has not properly diagnosed or fixed the real issue.

There's a chance it could have been the road / area I was in. Concrete sometimes gives me that feeling because of grooves and I was on elevated highway when I experienced the issue. When I tried to reproduce it, it was in another area with paved road. The setting change could have been just a coincidence.

You can’t categorize those as the same problem nor know if it’s the “same” symptom

 

[TBrownTX]

I'll do some more testing and will report back with additional details and specifics.

 

[DerbyDave]

I had the same symptom as the OP posted, and the same symptom as the TSB described. Sure , the cause could be anything.

This is pretty much what I am experiencing, or at least I think I am. 123 miles on the car, so have lots more figuring out to do.

Plaid vibration on hard acceleration

I'm getting a vibration from the car in Plaid mode at full throttle. At first I thought it might be the traction control but now I'm not sure. Anyone else have this same issue?

sounds like the half shafts need to be replaced.

 

[TBrownTX]

After adjusting to low ride height, I don’t notice anything today. I maybe looking for problems where none exist.

I’d have to drive another S to tell for sure, but I think I’m OK.

I’m now thinking it’s the different feel of AS tires versus the Summers I had on my M3P, maybe a little slippage happening.

If you have toolbox 3 you can disable the front drive unit

I have the same exact problem. I created a separate thread before about this. On hard acceleration, there is a noise and vibration from the front driver side axle. I can feel it go through the car.

I’ve been given a runaround by Tesla to fix this. A Tesla certified shop even put it on paper that I have a half axle issue, which I took Tesla but the foreman said it is not the axle and will be fixed by firmware in 2023. Fast forward 10 months and the issue is still there.

If you floor your car on even the slightest incline, do you feel or hear anything from your front axle?

You can also go full rear bias in track mode

Thanks to everyone who weighed in. I'm just going to let this go for now. The car is brand new, and the overall build quality is fantastic. I found very little to nitpick and nothing Tesla needs to address post-delivery, although I did log three minor issues in a Service Request to document them.

I'll get it looked at if I sense any shudder or vibes during daily usage. Otherwise, it's so subtle I'm questioning if it's really even there, and then only when flooring it. I'm just going to enjoy the car in the meantime and will rely on the 8-year or 150,000-mile warranty if needed.

That looks great! Can't wait for mine.

Love that red. That color is a winner! My 2020 is red, but yours is almost Candy-Apple Red.

I saw it about a year ago and had to have it!
