"Pop/Bang" Sound While Driving (not pre-conditioning)

[JasSwitch7]

Is it normal for the 2023 Tesla Model Y LR to have loud pop/bang sound after about 15 minute (~10 miles) of driving? The Model Y is not navigating to a supercharger.

Never had that sound when driving a 2023 Tesla Model 3 RWD LFP or 2021 VW ID.4. Only had pop/bangs when charging on previous vehicles.

Anyone have any comment on the issue? Or am I a one off situation?

Can you be more specific? Is it a suspension sound, related to road surface/speed?

 

[andaconda]

I get it occasionally when my battery is getting up to temp. -- happens more frequently in cold or cooler weather.

Not suspension - or at least I don't think it is. To me, it sounds more like the battery enclosure expanding/contracting, even though it's not navigating to a supercharger or charging.

Just a loud "pop" after about 10 mile/15 min of driving getting to/from work each day.

What temperature do you get it at? I'm in California and outside temperature right now ranges from 45-60*F.

I recently learned that this is the battery housing expanding or contracting as it changes temperature.

Just about any temp. I even get it in the summer. More so in the winter.

Also in SoCal, 2023 MY, 35 - 70*. I’m often on the road at 3:30am, other days 7:00am. I don’t precondition the battery.

I’ve never heard any popping or banging.

And I can feel the 'pop' under my feet when it happens. BTW I have a March 21 model.

Does it only happen at rest or when in motion?

Like the others have mentioned, sounds like the same effect as a baking sheet popping from warping when it goes in and out of the oven. Some sort of tension in the body panels and/or battery casing that hits a critical deflection point, causing the metal to pop as it warps. Tesla's way of simulating an engine backfire lol.

When I'm in motion - usually a few blocks from home.

That's exactly where I feel it and it usually happens within a couple of miles from my house. I've always assumed it was related to the battery heating up.

Interesting - so I guess I should just take it as normal and expect it to happen all the time regardless of temperature and/or pre-conditioning.

I don't precondition either - just get in the car and go to work around 8am in the morning - about 10-15 min in, one loud "pop".

I always thought it only happens on extreme temperature and/or preconditioning the battery to a fast charger.

Never had any issues with a 2023 Model 3 LFP or 2021 VW ID.4 when driving regularly and not heating battery for charging.

Appointment is on Saturday - got a quote of $240 for diagnostics. Chances of me paying for the diagnostic might be high if some say this is normal occurrence?

Did you listen to sounds on Tesla's online manual? I posted the link a few messages earlier. The metallic popping sound is normal.

Says while charging though?

While charging there is usually a temperature change which causes materials to expand. When two parts (battery casing vs chassis) expand differently, it creates a tension. When it moves to release the tension, it creates that popping sound. Could also happen while you drive., But of course it never hurts to have Tesla look at it. It could be something else.

I get a pop sound when pulling in or backing out of the driveway over the sloped sidewalk (only when it's cold). I've had Tesla Service look at it. It's the upper enclosure for the battery pack. Apparently it's a non issue, though slightly annoying. We always know when Fall is over and winter is here.

 

[GtiMart]

I get that here especially in winter as my battery warms up from driving. Same sound as when supercharging. Normal.
