How many have had PCS malfunction/failure?

[PungoteagueDave]

The context of this stat is the people who replied, not of every truck produced, though i would love to see that statistic.

Which is why it is invalid, no statistics that come from the study mean anything relevant to further analysis or any conclusion of PCS reliability. It seems there is a valid issue, but the poll is misleading. It's not actually a poll in the technical sense. I am a statistician, court certified - would advise claimants to conclude nothing from any self-selected poll, which will ALWAYS over-report concerns. Always. Usually by relative multiples compared to reality. Especially in an enthusiast forum environment. If this "result" were presented in a claim or tort situation, it would be thrown out, and even the plaintiff would have to acknowledge its invalidity.

The intent of the poll was not to generate a legal statistic for PCS failure rate, it was meant to draw attention to a seemingly frequently occurring critical issue with the vehicle, as more and more people were posting about it. Its not misleading as there was no described intent to collect data for legal purposes, nor to generate any statistic for any real analysis. and and additionally more than once i acknowledged how the poll is not only biased, but also not a reliable data set for determination of pcs reliability. Ive actually replied to other posters about these facts when they have made statements about the findings of the poll.

I've acknowledged that only Tesla has the data to determine statistically the true rate of PCS failure AS WELL AS the reason(s) for it.

I understand and don’t have a problem with asking the question to gain an anecdotal data point on how many participants in a thread on PCS failures have experienced such failures, only commented relative to what conclusions can be reached, which are essentially none, other than “a lot” if that’s the case, which it appears it is. But as a percentage of CTs, that number is irrelevant and highly misleading.

If we end up with 100 forum members with PCS failures, that’s significant no matter what percent of respondents it is, but we can say with some assurance that if the self selected sample size is 200 owners responding, there isn’t therefore a 50% PCS fail rate despite that being the calculated result- it’s an invalid percentage. I sense you get that, but others may not, especially the media trolls who would tout “Survey Shows XX Fail Rate on Cybertruck Charging Systems”.

I agree that no conclusion on the true objective rate of failure across all CTs ever produced, likelihood of failure, or the reason for the failures can be made from the poll in this thread.

1/17/26 - PCS2_a137 alert. Only charging at 24A on mobile charger.
Service appointment made for 2/4/26.
1/29/26 - PCS2_a094_acCharingUnavailable
1/30/26 - Dropped CT off at service center.
2/6/26 - Service completed! Charging normally now. G-version

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?

FS AWD. 24amp charging issues June 2025 pcs replaced from factory to revision E, in the shop now. L2 charging charging time discrepancy about 1-2 hours from my usual times. Estimate/diagnostics say replacement is due and it will be revision G. Vin 28xx

 

[Sjohnson20]

still more non-failures than failures I guess

 

[Ivessm]

So I posted earlier about a problem I was having going from 24amp charging from my Wall Connector to 48amp charging. The CT would not allow 48amp charging from the WC to the CT.
I notified service and on FEB 20 they replaced:

FERRITE ROUND CABLE FOR HARNESS(2134590-00-A)

POWER CONVERSION SYSTEM -48AMP(1777777-T2-G)

I can now charge @ 48amp from my WC.

Pay Type: Basic Vehicle Limited Warranty
2024 CT born 08/21 delivered 09/11/2024
VIN 031XXX
Error occured: 16,677 mi
Current mileage as of Apr 14, 2026: 17,546 mi

 

[BeefState]

Welp, add me to this list. 11,994 miles, Foundation AWD VIN 016XXX. Only charged at 24A last night and this morning had PCS fault error. Just put in service request- currently says 14 days until next available appointment

 

[UberNoob]

Ut Ohs had to change my vote to maybe PCS. Home Tesla gen 2 L2 charger and mobile charger is now giving errors a second after plugging in cyber light on the charge port turns red, error in the truck is PCS_a062 “external charge equipment not providing power” and error HVBATT_a174 “ unable to charge”. Went to a supercharger and it seems to be charging that way, now I don’t trust it. Next apt is 7 days out, messaged service, generic response.

 

[BeefState]

Now add me to the list of no AC charging and no superchargers conveniently located near me. Did I read somewhere others have had luck taking to service center early?

Earliest available appointment they had for me is May 5th and obviously can't limp it that long

Here is my invoice for my PCS2 replacement. Not sure what version I got. This was done in Aug 2025. VIN: 14xxx 2024 FS AWD CT

capture a message in the app Tesla service telling you what they installed. Looks like Rev J but first time I am seeing J.
Mine shows Rev -G:


POWER CONVERSION PCS 1.00
SYSTEM -48AMP(1777777-T2-G)

I think that's a copy paste error. The same number (1816026-S0-J) is listed under Ancillary Device Cluster which is what that part number links to in Tesla's parts catalog.
PCS number in EPC is still -G.
