POLL: vibration felt when slightly accelerating refresh Mode S Plaid or LR

[jebinc]

No, mirror still vibrates

@Hayseed_MS My solution to this was to install a counterweight on the outer/upper corner - a small blindspot mirror

 

[jebinc]

Well, got the car back, and so far, so good.... Looks like the 2nd generation half shafts might do the trick. Details attached...

Day 4 Update: Well, so far so good, but… I haven’t put a lot of miles on it. I have drive. It every day, wet and dry, and purposefully look for the issue to re-emerge, but not yet. Too early to declare victory, however.

When was your car built?

First week of August. Vin 4294xx

Curious if it comes back?.. I didnt have this issue on my Plaid for the first 2200 miles, then it appeared. To me it feels more like an electrical current buzz, like a grounding issue. Seems to happen at cetrain harmonic moment with just the right electrical current and drive speed (2% throttle and 37-45 mph).. It doesnt bother me, it affects nothing, and I consider it part of the electrical nature of the car..

@Rambino Exactly the same experience and thought. Started at 2200 miles and I told the SC I thought it was more electrical than mechanical. They ignored that and replaced the half shafts.

I agree with you. 100%.

Well, I guees

Well, I'll hope the later cars got the 2nd generation driveshafts. Mine is MF452xxx, built 10/20/21. I guess I'll have to wait until I put 2200 miles on it to see, as well.

We’d need to see what @jebinc has under his car in terms of part number stamp, and then we can compare to other cars.

@WilliamG. Nope, we already know what’s under @jebinc car. He posted the dang invoice with part numbers for all to see! What we need to know is what’s under your bastard! .

Ah yeah that’s true. It’s bloody cold out, though, and I’m not climbing under my car in the wet. Do we even know if those part numbers are even visible?

And I’m not climbing under you car either!

 

[jebinc]

Yes, as I posted earlier, the part number tag is clearly stuck to the shaft by the universal joint.

Example.

Nice. Alright! Who’s climbing under their car (Californians, looking at you) to get the part number off their car?

Day 6 Update: Cold, dry and higher SoC level (87%). Vibration returns, as somewhat expected. As you may recall, I always suspected it's electrical, but Tesla insisted on new half shafts.
@Rbats How is yours?

@WilliamG

 

[Mandarin]

I have reported this issue and will see what they going to do on my SC appointment in December. Thank you guys for posting updates.

 

[Mandarin]

No jack. Happy to compare to yours when we next get together. Not convinced about the bad batch argument, mind. This may just be a part that prematurely fails.

The same story with X. They were making new half-shafts for X a few times and they are still failing... And car starts shaking after 10-15k miles under hard acceleration.

Interesting, my car's BD is 6/18 and it has 433 VIN

Ugh. Even though I didn’t believe it would be the fix, I wanted to believe. Bleh. Useless, as usual, Tesla.
