2020 Shudder Issues

[ABC2D]

seems that 2020.20 firmware includes a software fix to shudder (= they just plan to reduce power or some such it would seem when the shudder is detected).

Ohhh, that's so dirty

My shudder issue was fixed a few months ago, I haven't even tried to test it since (verified the fix after I picked it up; no plans to do so again).

From my understanding, Tesla SC do not fix the shudder issue.. they said it's normal for these cars..

Tesla fixes the shudder problem in pre-Raven cars, but not in Ravens. The cause is different. Someone reported a recent software rollout addresses the problem in Ravens; I don't know if this is correct.

My 2020 MX LR+ is on 2020.16.2.1 and it definitely still has the problem.

Interesting and disappointing. How would the car detect shudder?

Tesla needs an engineering/hardware solution instead of software.

As mentioned in the previous post, one other minor suspension matter, besides shudder, that could become an annoyance with the S and X is rear wheel alignment.

The rear camber is non-adjustable and the rear toe has a very narrow adjustment range. So, there are many with rear inner tire cupping after less than 10,000 miles on new tires. It doesn’t happen to everyone but it does occur to many and can happen at any moment.

The solutions are: wait for a business to sell adjustable links, live with replacing tires prematurely, or don’t drive on low/very low. But, that last solution seems to accelerate shudder issues. There is an (pricey) aftermarket link in the works.

I had it installed a month ago. If you look under the car the driveshaft are straight and not angled. Minimum lowering height is 20mm to alleviate the problem. Www.N2itive.me

Hello!

Long time lurker. I've been eyeing the X for a long time, and am just a stone's throw away from signing and purchasing a LRX.

My main hesitation is the shudder issue, which makes me nervous. As far as I can tell from numerous forums, it's been seen on vehicles as recent as Dec 2019 according to some posters. I'm worried to spend 100k on a car I had hoped to keep for a long time, only to repair the half shafts/etc every 10-15k miles for perpetuity of the vehicle. Some forum polls were showing 1/4 of the X's had this problem.

I'm hoping someone knows the likelihood of it happening to a 2020 version, and if there is an actual permanent fix for it. I had hoped to drive it at the height of my preference, and drive aggressive at times, without having to worry about causing shudder. I feel that placing it on low height all the time, and driving conservatively to prevent a known issue limits its capability. It's like buying a toy, but you can't fully play with all it's features in fear of breaking it, albeit an expensive one.

Anyone that can shed light on this would be immensely appreciated. =)

Sorry for my wall of text.

There is no perminate fix but there is a software fix for it. Its called chill mode. They should change it to axle saving mode.

Chill mode didnt work for me on my 2020 MX LR. I ALWAYS keep it in Chill mode + range mode. Its starting to appear now.
