I just got my truck back from service for the cantrail recall, lightbar recall, and PCS2 replacement. Cantrail has the stud bump now, but it's not too annoying. Lightbar was completely replaced and additional brackets installed. I had to reconnect the wiring harness and remove the blackout strip. PCS2 replacement is the T2-G revision and appears to operate normally. I had to wait 3 months for the PCS2 and service time took almost a week due to high repair volume and only 3 HV techs available. My service center provided a new Model X Plaid as a loaner. It was nice being incognito again on the streets, but the steering wheel made me feel like I was driving a bus.

What is the T2 part of the replacement ?

What is the T2 part of the replacement ?

There's a 1777777-12-G which is still affected by the PCs failures. Supposedly the 1777777-T2-G isn't affected, although some forum users are still reporting some kind of PCS related warning even after receiving the T2-G replacement part.

I received T2-G in December replacing my original PCS in a 2025 July build
48amp AC/325 kw DC since, perfect
No 500kw local but waiting to find and test

They are setting me up for my second PCS replacement in 2 months, but this time also replacing the HV harness they say they didn’t need to replace the first time. I started getting notifications again after having mine replaced to the G version two months ago. I’ve been waiting for their response to why I’m having PCS failures again after replacement. I noticed on other invoices that the High Voltage Harness was also replaced, and mine was not. So I asked them about it. Here’s my initial invoice and their response:

That ferrite filter seams to be vital. To me it says voltage spikes were too high for the chips in use. At least what I've seen of the design, it is a low capacitance high frequency switching system. They can be quite tricky to get right.

Interesting, they had replaced different cabling on mine.

Can confirm my August 2024 Cyberbeast PCS controller failed on me March 10th. It was plugged in and charging (Tesla L2 standard charger) when it failed.

Just got notification of PCS2 repair completed with ferrite round cable and HV harness replacement.
