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

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!

Quite.
The motor and transmission of an EV are simple and run cool enough not to progressively destroy their own lubricant so should not need much attention, batteries OTOH may require maintenance but I would have expected only the cells themselves except in the case of mecahical damage to the enclosure.

Engine mechanics need re-training to service batteries with more urgency than servicing EV power trains.

They might start selling Porsches for $999 and then kill you with those crazy repair cost.

That would make Porsches the most popular car in the world. If it cannot be repaired for under a $999, just order a new one. Heck, cheaper to get a new one than do the 2 year service. The car can use cheap parts if it only has to last 2 years.

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.

I imagine they’ll take a leaf out of the Royal family’s doctrine. Never complain, never explain!

It would be helpful to know what force is actually required to cause this sort of damage.

Would Going slowly (say 15mph) over something sticking up produce a dent like this, or do you need to be giving it the beans at the same time?

give some comfort (or otherwise) about how likely it is ever to happen.

As for gravel mode in a CT, I wonder if they might want to call it something else? ‘Well manicured cricket pitch’ mode or something.

Maybe some organization should impose a/some standard format(s) of battery, to ease repairs and replacement (the European Union? Same way they imposed the Type-2 + CCS plugs).

It will be basis physics....

Imagine stopping in Lift mode over a sharpish object of very high density (let's say a very sharp granite rock on solid ground).

Then lower the car so all it's weight bares down.

Would the undetray give or would the car balance on the rock?

If the tray dents, then the answer is 0 mph depending on circumstances.

it is interesting, Gravel mode stiffens the suspension as well as lifting the car, I use it on poor quality, undulating single track roads to prevent bottoming out while pressing on.

Ditto.

Update and clarification message from the dealer yesterday evening:
I missed your message yesterday. The actual battery case is what has been damaged and needs to be replaced. The case that houses the battery cells is where the cooling passages run, yes. The issue being, the case with the cooling channels is not a serviceable and replaceable part. Since it's been damaged, it needs to be replaced. It's an issue where we can't get that housing for replacement without replacing the complete unit. I also spoke with the tech about the coolant temperature monitoring. The Taycan senses coolant temperatures at the inlet and outlet of the battery, and without cell malfunction, it wouldn't alert us to an issue or coolant blockage until the whole unit started to overheat.

The coolant channel wasn't malfunctioning through, right?

It was effectively a cosmetic issue to the housing, which I understand them wanting to fix for liability reasons...I guess. But it's such overkill.

Correct, no cooling issues, but they did caveat that at the end of the message (which I think is BS anyway)

This would be correct. If a single cooling passage was blocked it may lead to a local battery hot spot which would not show up in the outlet temperature once the coolant is mixed up flowing through the whole pack.

A local hot spot is bad news.

The computer should be able to read individual cell temperatures and indicate a hot spot if there was one. This should all be part of the BMS.
