New heating system - shortage of components for new delivery

[TXSchnee]

Contacted my SA, per their internal system I should still be able to pickup the vehicle end of the month, nothing is showing as a Recall or Stop Sale. However Porsche has changed the pop up on US Track Your Dream to say:
Due to a temporary supply shortage, Porsche is currently experiencing a shortage of heating modules (cabin heating) designed specifically for Taycan. As a result of this situation, certain Taycan vehicles are currently being held at US ports until heating modules can be installed. Porsche is working diligently to address this issue, and regrets that your anticipated vehicle delivery date is being delayed. As always, we ask that you stay in close contact with your Porsche dealer for updates on your vehicle delivery timing.

We thank you for your patience and your loyalty.

I would like to confirm that the "Heater" part that we are talking about is not the matrix that pre-heats the HV battery (looks like a net around the battery), it is actually the cabin heater which is basically a coil that heats up the air flow going into the cabin.

Super helpful, I also found this shared on another thread. So this part controls all heat.

This is not a good design to me to have a single point of failure to disrupt the heating fuction throughout if >>> "The failed component, according to a technical explainer by Porsche magazine Excellence, exists to rapidly reheat the coolant coming back toward the cabin from the Taycan's electric motors and inverter. This heating circuit is shared for cabin heating, defrosting, and to aid in the pre-conditioning of the battery back itself. When the component fails, these crucial items are disrupted, resulting in the need for a six-hour fix from the dealer. "

The cooling/heating system for the Taycan is much more complex than in an IC engiined car but neither typically has aircraft level redundancy built in so having a single point of failure in a car is normal not bad design.
What may be bad design is the heater element itself unless it is a failure in manufacturing consistent parts, which could of course also be due to poor design.
