I had mine replaced at ~16,000 miles on my ‘24 FS AWD. Quick fix, several months ago.
Had a discussion a few weeks ago with the service mgr about this at My SC. She said they aren’t seeing a lot of failed PCS…
Just an issue with parts availability.
“trickling in” were her exact words.

It's an expensive part. They wouldn't want to keep too many in inventory.

I believe labor is a huge factor.
Apparently trucks with terrestrial armor require an additional 8 hours of labor

Quote from this article:
https://www.notateslaapp.com/news/3989/tesla-should-recall-the-cybertruck-pcs

“Fixing a failed PCS is not a simple parts swap. Because the unit is buried deep within the vehicle's architecture, service technicians must remove the tonneau cover, the bed floor, and elements of the air suspension just to access it.

Under the primary Basic Vehicle Limited Warranty (4 years or 50,000 miles), Tesla covers replacement, often installing an updated hardware revision (Rev G) along with a new wiring harness.

However, for high-mileage owners whose trucks are already out of warranty, the costs have been staggering. Previously, an out-of-warranty PCS replacement cost between $5,000 and $7,200 for parts and labor. Tesla has recently lowered this cost to approximately $1,000 as a "goodwill" gesture, but owners are still footing the bill for what appears to be a systemic hardware defect.”

Here’s another article on not a Tesla app discussing Teslas current strategy to address this issue:

The armor doesn't need removed
The rear skip plate can slide out if the rear tires are removed.

Charge rates are not being restricted.

The PCS is a pair of 24A circuits. Max amperage drops in half when one of them fails.

Tesla Cybertruck 80% of CyberTrucks have this problem with charging: PCS arzkbw


Pretty sure I’ve figured out why the PCS modules failed all at once…

Just quoting the article (2nd link in my post)

But I will definitely defer to anyone who has personally performed or witnessed someone performing the procedure on a truck with Terrestrial Armor

From the article…

The Terrestrial Armor Problem
The already invasive repair process becomes significantly more complex for vehicles equipped with the Terrestrial Armor retrofit or factory package. This heavy-duty underbody shield must be fully removed and carefully reinstalled to access the deeply buried power electronics.”

When I heard they were doing bidirectional direct conversion, flashbacks to my linear motor days ricocheted through my head.

I just got my notice today... Unit 8848 and I have 27K miles... As others have stated, Supercharging works fine. Im still able to charge at home at 24amps (for now).

Was told it's not a matter of stock but rather they are reengineering the part so who knows how long it will take.

also realized this week non of the power plugs work on the truck due to thi

We should be compensated, this sucks.

The circuit that is dying is responsible for charging the battery from an AC source AND creating AC output from the battery. So when one goes, the other is dead too.

edit: added that pesky missing 'y'.

Yah, the article says that, but I talked with a tech who said otherwise after it was published. Key factor is that while the park armor overlaps the rear plate (which covers the PCS), the plate can be slid out from under the armor. That's at least part of the reason the older trucks need their plate replaced when installing the armor.

That would be good news for me. Traded in my ‘24 FS AWD for a ‘26 Premium AWD with Factory Terrestrial Armor less than two weeks ago.
