How many have had PCS malfunction/failure?

[Sandman1962]

I got revision F. I hope it doesn’t fail. Or maybe I hope it fails sooner than later…

Wow… 50+ PCS failures… that is shocking… this is not a small sample. I know it is relative to “every ct sold” but damn, one part in isolation failing this much in such a small group… genuinely curious what the actual number of failures has been.

Exactly, and that's just us here on the forum. Very concerning to be honest..

It is going to be offered apparently. I'll definitely get it before I hit 50k.

Well they better offer it soon…I’m at almost 49,000 miles…

I had a weird PCS-related issue at about 2% SOC approaching a Supercharger on the freeway, truck went into limp and then zero throttle input, but allowed me to pull over and stop safely. Exiting the truck and locking, then reentering, the truck restarted as if nothing had happened. Service center reviewed and called it an anomaly due to low SOC. If my PCS fails I intend to refer back to this incident as evidence of failure under warranty. I’m eager to see the feedback in your thread as to cost out of warranty. Thanks for posting the poll.

Got my estimate:

Interesting. The wiring harness to the PCS but not the PCS itself? Hopefully it fixes it!

I have to say … and I’m not sure it’s related but since the replacement I am no longer hearing that high pitched interference from my stereo speakers anymore. The whine noise from the speakers

Our Cybertrucks are now brothers from different mothers
They installed Rev G in mine also

This is the way

The exact same 3 parts replaced on mine November 2025.
After the replacement, I am now getting back to 254 miles at 80% charge. Same as when I originally got my CT.

To be fair, as far as i know, my pcs has worked fine since replacement. Havent checked service alerts recently but no pcs related notices, 9 months and like 7k miles later

 

[kpanda17]

lets keep track with the PCS hardware revisions, looking for 2x replacements:

-E Jcerrn is E, says working perfectly after 1x replacement
-F
-G Im G, working perfectly after 1x replacement

anyone have a 2nd PCS replaced, what was and is the hardware rev?
