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

[Landen420]

Do you mean the alignment of the wheels? That has been done 2 times by tesla and 1 time by a tire specialist. I had issues with cupping. They said that the alignment done by Tesla was (totally) incorrect.

DO NOT TRUST TESLA WHEEL ALIGNMENT!

So I had a wheel alignment done this am at a performance shop because I recently threw some new wheels on my car and the driver side wheel was rubbing the front of the wheel well. Whats funny is that just 2 months ago, I had Tesla do a wheel alignment because i noticed some veering. Well, they fixed the toe and camber which fixed the veering but didn't align the castor which is part of a "wheel alignment". It just amazes me the half ass job they do at their service center.

After my alignment this am, the rubbing was mostly gone and only rubs in reverse at full lock but that is because I am running 255/35/21 in the front which is a smidge above the max.

yes that is what I meant. Glad you had it checked.

This is my before (so, after Tesla did it) and after.

Hi just recently took delivery on a P100D and on hard acceleration I have a rattle with vibration, also known as the half shaft shudder which affects cars with the air suspension and more typically performance versions since it develops more torque. It's most pronounced if the car is in the standard or high setting. Apparently the fix is replacing the half shafts and jack shaft but in most cases this is a temporary fix since it often returns. Owners are reporting that if they drop the car then the aforementioned repair results in a more durable fix. Just wondering what percentage of cars are

I experience this in 2019 Model X with air suspension. My house is located on a hilly, bumpy, dirt road and the suspension is set to high when leaving the house. I have a knocking in the front driver's side tire. Once on paved roads, the suspension is lowered to standard, knocking stops. I then have to take off from a dead stop onto a highway, which usually means hard acceleration. This is where I felt the strongest of "shudders." It was taken in for an adjustment and the shudder problem from a dead stop to hard accelerations has been resolved, but the knocking on the high setting on the hilly, bumpy, dirt road has returned. I'm looking into purchasing a Model S with air suspension, so I guess this problem will turn into a general maintenance issue for my vehicles. That's what I get for living out in the middle of nowhere.

It is most certainly weather related. In warm climate, the sound disappears. Thats’s probably why this isn’t getting real attention, since in California it’s always warm. I’ve had it ... I want my money back, or I’m gonna sue. Already set things in motion.

How was this resolved for you?

Did you get a new car or your money back or a fix?

Thanks!

Does anyone know if they solved this problem for Model 3 and Y?

I've actually never heard of the M3 or MY having this issue?

Is this a "thing" or just a concern that they might?

Well, I half expected the "problem" to be fixed in my new Model S, which it clearly isn't. Actually comfort mode in the suspension makes it worse, since there's more front-end lift under even mild acceleration. A problem in itself which without hardware changes could be compensated for in software, IF engineering was not oblivious to the issue.

So, I wonder about the state of 3/Y. Especially since it's likely that Y has a higher halfshaft angle.

Had both my front axles replaced on my 2020 MS LR, then had to have a front wheel speed sensor replaced about 2 weeks later........

 

[Jamojones]

Nope
Not a traction control issue, definitely a design issue which is why Tesla issued a service bulletin. Mine is fixed for now. Apparently ravens have the same issue.

I have a 2020 Model X with all the exact same issues I've seen others describe. I've seen the service bulletin dated June 25th 2019. I am currently scheduled for service and it looks like TSLA is doing this half shaft repair AGIAN. This is the 2nd time in less than a year on something thats about a year old. Have TSLA or any other owners come up with a better solution than repeatedly having these half shafts replaced? As long as TSLA is paying for it they can do it every month, but what happens when my warranty runs out? I shouldn't have to pay for this problem.

I have the same problem with my 2020 Model s. Parts are on order and planned repair in replacing both half seats next week.

You're lucky--my local SC won't even bother to replace them.

However, I don't like hearing this garbage on nearly every high power acceleration so it's going back for a replacement, or so I'll be demanding. I don't really care that it might happen again, or if they have to schedule a fix every few months--perhaps that'll serve as an incentive to fix the damn problem once and for all?

I have had both front half shafts replaced twice (March 2020 and October 2020). Unfortunately, shudder still persists despite driving on Low suspension setting after the last replacement. The shudder occurs even during moderate acceleration. I will wait to see if the next redesigned parts offer a permanent fix for others.

Consider doing what I always do with cars, sell before the warranty runs out

 

[AWDtsla]

Now there is a TSB. Seems unclear if this is a permanent fix. Can someone compare the part #'s perhaps?

Thanks for posting this! I'll contact my SC (well, at least I'll try to through Tesla app) and see what they say.

Really hoping they engineered a fix.

I suspect that they've finally had to get the right parts found/made as the Plaid and Plaid+ would have become a joke within a few weeks/months if they had not done so.

Thus, retrofitting our cars with the stronger and more durable parts is likely what's going on now, FINALLY.

Pure speculation, of course, but hope someone will compare these part numbers to those on the next generation Model S's and X's; then we might know for sure.

My front cv half shafts were replaced 4 times. They NEVER tried to tell me it was normal. The 3rd replacement at 50K miles and it only took 3K miles for the vibration to come back. They asked me to hang tight until they found a permanent solution. By 70K miles it was worse than it had ever been mainly becuase I had the 3rd set for 17K miles of vibration.

I asked them to put it in writing that the violent shaking would result in any metal fatigue of suspension components and that there was no danger. Once I asked for that in writing, they asked me to come in again and have them replace. That was at 70K miles...20K miles ago and the problem hasn't returned since. I'm fairly certain it's because I lowered the car 1" with lowering links so it is now at the height it was when the drivetrain was qualified. Tesla raised the car 1" in 2014 for fear of battery strikes. I believe this exceeded the angular design limits for the cv shafts while under heavy torque.

Hi Sir,

May I know if this half shafts replacement were done warranty past 50k?

Thanks,
Howrad

has anyone had this May 21 TSB done yet? starting to feel rattle (I think) also on very low now. 2019 raven.

Waiting for confirmation that it actually fixes the problem before trying the schedule my car. Who's got a bunch of time to waste?
