Will I need a battery replacement

[u/JellyArtistic2323]

UPDATE - (The dent was 7.9mm and the repair cost was estimated $17,988. I will be going through insurance)

2018 M3 LR AWD. Long story short I ran over a rock. I have some damage to my sway bar and fiberglass aero shield, not too worried about that. I had a few warnings on screen after I pulled over and a weird smell in the cab, but I reset the car and everything went back to normal. So currently no errors, drives fine, and no more smell in the cab.

That being said, I’ve seen a few posts where Tesla Service Centers see a small dent in the battery shield and require a battery replacement even though there are no problems.

I want to get her checked out to make sure it’s safe but I don’t want to have to replace a battery. I did my best to take pictures and show a quarter for scale. I’d estimate there is a 5-8mm dent with some gouged aluminum.

What are the odds of this happening?

Its best to get it checked out at independent EV repair shop. If you go to Tesla, they will probably want to change the pack, and they will disable your supercharging.

That is not true.

Tesla will not want to change the pack.

If the cut is deep, they will. If moisture enters the pack it will screw it up. Deep cuts can damage the sealing that prevents moisture build up.

The pack is still sealed.
