I'm guessing this is a one-off unique situation but hoping it may help others in a similar situation. I had not received a PCS Alert but had my PCS2 replaced under warranty. Here goes...
On April 24th, I informed my SC that my VIN was most likely w/in the range of defective PCS units (1777777-12-E) and with 5000mi left on my warranty after 16 months of ownership, I wanted to schedule a replacement. *I had not received any PCS Alerts. On April 29th, I received a message stating that remote diagnostics had been run and that my CT's charging system required service and that they were ordering the part. I was told that I would be receiving free super-charging but that was a mute point, as I have lifetime charging on the truck. My cost estimate invoice, showed that a new PCS (T2-G) and harness were on their way. After a couple of pushed back appointments due to the PCS not arriving, it finally arrived on June 5th.
On June 18th, I drove from Reno to the Bay, as the SC there is the best I've been to and the employees are exceptionally good!! As I dropped off the vehicle, I was asked if I had received any notifications from Tesla about my PCS or if I had received any alerts. I informed the service worker that I hadn't and he then informed me that they hadn't seen any either. It was explained to me that they wouldn't be able to do a PCS replacement as there weren't any alerts and couldn't do anything pro-actively, even with me close to the end of my warranty. I was shown a screen that said I had a PCS2 and that it was the new version as indicated by the 2. I explained that the PCS2 was the PCS designed especially for the CT and that they needed to look at my actual PCS2 serial number. I then asked why the part was ordered, why I was asked to schedule an appointment and why I had a message stating that remote diagnostics found a charging system issue. That changed the conversation and the truck was taken in and a loaner provided. My initial appointment said that the replacement would be completed that day for pickup at 5pm (this was a Thursday). Before leaving the SC, I was informed that the truck would probably not be ready until Monday the 22nd, but when I returned home, my app showed that it would be ready at 5pm on Tuesday the 23rd. I was told that it's usually a 4-6 business day job, after asking why they needed it for so long, given the 4.2 FRT suggested by Tesla. *SC was great with the loaner as we needed to exceed the 200mile daily allotment.
On June 19th, I received a message at 1pm, stating that the truck was ready. Here is the alert I was able to pull up on the day of repair when they had it.
This is the only PCS alert I ever saw and it appeared on 6/19/26 - PCS2_a128_cycloBgdpsHealthCheckFailed - The PCS2 has failed the self-performed Gate Drive Power Supply health check on Cyclo Converter B.
My Service Summary states that my high voltage battery showed reduced maximum range and that the PCS required service. The PCS was replaced and the ferrite round cable for the harness was installed. I've reached out to the SC for clarification on the high voltage battery issue.
Extremely grateful to the SC and staff for replacing my PCS under warranty and wondering if others can have the same Gate Drive Power Supply health check performed, as a possible way to get a PCS replacement. My CT was showing no alerts and no issues until that check was made.
*I did find a small button head Torx machine screw with witness marks in the bed, so I'm hoping it's not for a protective shield or something important.
**More importantly, do I get a new and different badge, since I've had it replaced but without failure? hahaha!!!
Good Luck!
