Truck Vibration at Higher Speeds

[btcrealm]

This started a month or so ago. I had an initial ticket open on a recent service and was using that but Tesla closed it while I was still troubleshooting.

This is my current description to Tesla:

For a little while now there has been a rattle at higher speeds. In a traditional vehicle I would say it is alignment, tire balance, suspension problem.
Sometimes starting about 60mph a slight vibration can be felt.
At 70mph there is always a slight vibration, 75 it sometimes gets noticeably worse. At 80 it can be a shaking the vehicle vibration or just a noticeable vibration. At 90 it is always a shaking the vehicle vibration.
It does not seem to matter how I get there. I've ramped up slowly, put the accelerator to the floor, launched. The result is always similar at the time.
It doesn't seem like an alignment because of the inconsistency of the shake.
I've had the tires rotated, balanced, and checked. They don't seem to be the problem.
It does not seem to effect general functionality of the truck.
This was brought up after the last service visit but they only installed the wheel covers. Through testing this was also discounted.

After a drive a few days ago I smelled electrical, it was strong enough to notice getting out of the truck. Hard to explain but there is an electrical smell when something over heats vs burns out, it seemed like the prior, I've looked but there are no warning codes. I couldn't tell if it was the driver side front or rear wheel well, the front smelled stronger. Once since then I've gotten a whiff but nothing strong from the same side. I've been checking it.

I can't say the two were related but it seems like it would be.

I've looked around on the forums but this was the only thing I could find on vehicle shaking. I don't know if it is a similar problem.

I've had the truck since August and been over 90mph many times (when launching people I've taken it to 90mph a lot), I've never experienced this shaking until recently.
This isn't related to recent off-roading trips as it was prior to that. I've tried to find anything wrong with the suspension but really there isn't much to check visually.

Just curious if anyone else has had a similar problem so I can present something to Tesla.
Thanks

I’d start with a tires balance. Beads could have broken inside the rubber, this happens if you hit speed bumps or train tracks, pot holes etc too hard.

I had that done after I started talking with Tesla about it. They did some weight change but overall they said the balance on the tires was good.

try a discount tire or whatever is comparable in your area. A 2nd opinion can’t hurt. not to bash Tesla SC, sometimes them guys just don’t care and want to close the ticket vs customer care.

I had a similar issue wirh original s at 2k. I bought a complete extra set with 200miles. Had them re-balanced. Vibration almost but eliminated. Agree with others start with your tires.

Exact same thing happening to me around 80 mph. May try tire balancing after reading this thread too.

The foam Is lose. Get tire pulled off wheels

Thanks, I'll have another tire shop pull them and do a balance on them.
That was my initial go to but thought I had ruled that out.
Its going into the Tesla collision center for deer damage on the frunk but once I get it back I'll have it done if they don't figure it out.

I will report back, it may just be a while. They initially quoted me a month but sounding like 2 weeks.

Thank you all for the input. Yes this is 100% foam in the tires becoming unglued.

Neither the service center or the repair shop knew anything about it when I brought it up or brought it in.

The repair shop did say they had 2 other vehicles come in with similar problems while they had my truck. I'm guessing there were known complaints but until I said "Everyone on the forums is telling me its the foam" they had no idea to look at it.

They did look into it and its apparently a glue change with GOODYEAR tires and an issue they are currently fighting (GOODYEAR) and that Tesla is waiting on new AT tires with a new glue compound.
Their solution is to rip the foam out of the tires (they did this on all 4 tires for me). They stated its not as much about road noise as it is about deadening road impacts.
