Thunk, clunk, pop, “scrape”?

Now I hear the same thud sound when driving up the ramp turning right.



22” MYP

My 2021 MYLR still makes this crunching sound when turning right, entering a steep driveway. I have Tesla fanatic friends (high mileage M3 owners) who say this is the ABS system cycling when it detects a slight loss of traction, regardless of vehicle speed.

interesting! Hope so.

funny is only when making a right turn going up. Also driveways. Lol

...and I've got 44k miles, zero suspension/abs/traction control issues.

You will hear it at the 9 to 10 second mark in the video. It’s a loud thud sound.

I get something similar in a new 23 MYP when turning the wheel all the way and reversing to park

Also you guys should go over speed bumps with two wheels (instead of one at a time) to distribute the load as evenly as possible, imo

 

[niktesila]

The loud thud sound went away by itself after the weather becomes warmer.

 

[yellowr6]

Same here. I don’t even hear it anymore.

but when I’m fast DC charging from low SOC , I can hear pop every now and then. Maybe the battery metal protection shield expanding?

I had the same issue turning into my driveway which has a small incline. I’d hear two clunks and thought it was a sway endlink bar from a YouTuber. I took it into Tesla and the technician drove back to my house to recreate the problem. So, it’s not the endlink but rather the HV battery. Here’s the technician’s explanation. Tesla went above and beyond fixing the problem and appeasing my concerns. I’m a happy man.

Service Summary
Technician Notes

After further diagnoses, it was found that the HV battery had insufficient compression strips along the battery which would cause a "thumping" noise when the chassis would flex. To repair this concern, the HV battery was removed and compression strips were added along the battery. The HV battery was installed and verfied the concern was no longer present. Your Model Y was taken on a post repair validation test drive to ensure no thumping could heard from the right side.

I had the same issue. This fixed the problem.

After further diagnoses it was found that the HV battery had insufficient compression strips long the battery which would causing a "thumping" noise when the chassis would flex.

Mind giving us your VIN serial number? Last 6 digits. I have a sort of similar clunk in the colder weather when the battery is cold.... Wondering if they neglected to put these strips on a batch of cars?

i also have the same issue. Tech only re tighten the bolts to spec. But problem still exists.

I suspect I have the same problem. Unfortunately I’m two hours from the nearest service center. Did you get an idea if it’s dangerous, or just a nuisance? I can live with the noise. It also goes away when it’s warmer

My 2024 LR that was picked up on 2/1/2024 is now exhibiting the same KNOCK KNOCK noise while I turn RIGHT onto my driveway at slow speeds. It sounds like rocks being slung up against the plastic fender liner when this happens. It happened twice yesterday and both times involved me making slow, 90 degree turns onto or out of a driveway.

 

[Pianewman]

To repeat:

EVERY TIME I make a right 90 degree turn, into a driveway, with a slight gutter dip and a rising driveway apron, I hear a brief grind/crunch. It has done this for 51.ooo miles.
I believe it's the traction control engaging, when the right rear (inside) wheel loses traction.

It happens every time.

No other suspension/drivetrain/traction control issue of any kind. 51,000 miles. Actually, ZERO issues of any kind. The car has been flawless (except for steering column in/out/up/down motors that were replaced very early on, because of a grinding sound)
