Thumping Sound While Driving

[Cool Car]

We recently had the rear passenger tire flat repaired. The garage used the chassis pucks and lifted just the rear of the car to fix the tire.

Several days after this repair, while driving we now hear a periodic Thumping Sound in the floor area from the rear portion of the car. If we drive 20 miles, we may hear it up to 2 times. I have inspected the underside of the car at the lifting points and there is no abnormal findings…all looks good.

Just wondering if the stress of lift the car or even the colder temperatures we are experiencing is causing an oil-can metal deformation sound somewhere is the floorboard area?

Any input would b e appreciated!

Were you driving Up hill at the time of the sound? or possibly just finished supercharging? The sound and location sounds like expansion of the metal around the battery pack, which is perfectly normal. Scared the daylights out of me the first time it happened on our Model 3. The timing of the tire fix, may be just coincidental.

804son, thanks for your input. I just wanted to make sure my car wasn’t falling apart!

Since getting my rear tires replaced, I've been hearing this thumping / popping noise occasionally while driving. It's the same noise as you hear at a supercharger. I'm not convinced it's normal because it started after the tire repair.

Foam in tire loose?

My 2022 MYP does the same.

while charging from low SOC. I would heard the “popping” sound coming from the battery pack. liked meter expanding.

also while driving uphill and during a slow right turns. Only right turns, not left.
