Thump sound when starting to step on gas

[bsk997]

I was just wondering if anybody else has this problem/annoyance?

When I'm stopped, let off the brakes and press on the gas, I can hear a slight thump that's coming from the rear of the car(transmission)? Sounds like transmission engaging. Is this normal for the car or should I take it in to be looked at.


This was a CPO car and I've had it for about 2 months now.
I've only noticed it recently since I normally have music on but the kids have the been in the car recently and they take naps after a long day at Disneyland so everything is off.

Thanks for your input.

If you have pressed on the brakes hard enough to engage brake hold, the sound could be the brakes releasing. Otherwise, it is not normal. There is no transmission to engage, just a fixed gear reduction.

Hmm I think I have this too and thought it was normal. It hasn't gotten any worse in the 4 months I have had my car. Time to call the service center I guess.

What? You have a *gas* pedal? WTF?

Sorry, couldn't resist...

Your car does not have a "transmission", it has a single fixed reduction gear and no clutch (of course it also doesn't have a "gas" pedal, but I understand you are referring to the accelerator pedal)..

Take it in to your local Service Center and have them listen to the sound.

If your TMC Profile "Location" is showing your Zip Code then I assume you are in Yorba Linda CA and Buena Park is quite close to you.

hey @bsk997 I posted a video of my car in the other thread. If that is what your car sounds like it may be helpful in diagnosing the problem. https://teslamotorsclub.com/tmc/posts/1725577/

I thought you said "Trump sound". Nevermind.

Help! My car is retweeting white nationalists!

A muted thump is the sound of a sonic boom from inside the cabin as you break through the sound barrier.

Not many drivers on the road in other cars get to experience that.

Enjoy!

I noticed the same in my wife's car yesterday (just over 30K miles). Her 90D is due in this month with her car going to her father. I'll have service take a listen if I can get a repeatable scenario. I'll post if they respond with anything useful.

If you get Trump sound when accelerating I would check the trunk immediately.

Just for completion I will repeat what I said in the other thread: After a ride long with a service center tech, they said it was a hub lubrication issue. Taking the car in for service next Friday.

How about the thump of a trump going under the wheels???

 

[bsk997]

Thanks for the input guys.
Sounds like a lubrication issue from the previous other posts.
I'll have to find time to bring it in soon. Let's see how long socal's service wait time is.
