Underbody Protection Panel damaged. Batteries and coolant lines need inspection. $72.5K replacement & labor cost. Dealership is Tom Wood in Indiana

I fail to see why this whole assembly is not repairable. If the aluminium tray was removed and revealed damage to the cooling pipes/assembly, aren't these capable of being repaired/replaced? And if any cells are damaged, again they could be replaced, at a fraction of the cost.

It seems like an over-reaction from Porsche. If it's slightly over tolerance - replace. Someone else is picking up the tab so why should we worry?

I've seen a pretty new GT3 engine being rebuilt at Silverstone - they don't throw the old one away! Why not rebuild batteries?

Why not rebuild batteries?

I am sure it is a shortage of parts and people who can safely work on batteries.

This dent looks like it is in the cooling channel that runs width wise across the bottom of the battery and does not appear to protrude into the battery itself. Did you end up getting a confirmation picture that the battery itself was dented? If it was, I'm surprised no one has pointed out the fact that a dent being over the threshold by 0.3mm could have done that much damage. If it is just the cooling channel, which I suspect, the service could be as simple as removing that channel, which appears glued on, or just doing some "bodywork" to pull the dent out to ensure you have proper coolant flow.

This is my own speculation on the construction methods, but you can see the impressions of the internal cooling channel fins on the bottom of those sections protruding from the flat base plate. Likely made from aluminum and adhered to the steel base structure that the battery sits above.

A pinch like that in the extrusion would compromise cooling for 3 battery modules. It's interesting that it appears to be glued in place, probably with some thermally conductive adhesive.

I can understand why Porsche doesn't want to fix something like that, but it looks eminently repairable by competent technicians. It might be cheaper to replace the entire battery tray and move the modules, but from the exploded view posted it looks like the cooling assembly should be replaceable.

If this is dealer overreach (greed) Porsche needs to squash this quickly and to OPs satisfaction.

This is going to be a huge deterrent to their EV products if not handled well.

Not sure if you have included this video in the thread? I could not find it when I browsed through the thread. Look at the solid crash structure the Porsche guy is talking about. I am totally confused how the battery modules have gotten end damage at all. Cooling plate yes but not dramatic.

This is great, I'm definitely going to watch that when I'm done with work

You know those junk packages they try to sell on the way out the door? Wheel/tire protection etc?
They need to make one for glass (all) protection, and one for underbody/battery protection.

I would actually buy those.

Wheel repair $200. Roof glass replacement $16,000. Wheel protection package $4,000. Glass protection package $80,000 assuming 4x less chance of damage. would you still be interested in buying this particular junk package?

I'm completely with you, from what I could see there's absolutely zero chance that a 3.33 mm dent could get close to the battery, especially due to the crash tray

 

[whitex]

Nope!!

That’s probably why they don’t bother offering it.

Perhaps the cooling flow distribution relies on the centre channel such that when it becomes restricted the whole battery overheats (i.e. the other channels are fed from it), if so that must be a design flaw.

Will be very interesting to see how Porsche mothership responds.

No temp issues as well as no error codes and/or lights

 

[Maelstrom]

Pretty sure the hex bolt is longer than 3.33mm too, granted it's engineered to miss cooling lines etc. but the length is the key, surely is cant touch the crash tray either???

I can only hope this is being addressed by Porsche. Their technicians will need to spend less time on GT3 engines to becoming proficient with electric ones!

I am so distressed reading the post; it is just wrong. I’m sorry OP. an over engineered vehicle is not a well-engineered one, and clearly Porsche is a brand to avoid for me. I can’t stomach the fact that their repair costs are shamelessly so high.
They might start selling Porsches for $999 and then kill you with those crazy repair cost.
