NEW PCS (Power Conversion System) Failure & Replacement News

[rlac]

No, it was a one time run based on the data up to the 19th. Anyone with Perplexity computer credits can re run it I would think.

Update on my PCS failure. I had had a service appointment scheduled for today but recieved a call from my service center yesterday. They said they didn't have the PCS and would like to reschedule the appointment for when the part came in. I was also getting the cantrail and light bar recall work performed, but they would rather get it all done at once.

The service manager mentioned that my truck was scheduled for the update that would allow free supercharging, but I haven't seen the software update option yet. I'm currently able to supercharge and I know others are unable to. Hopefully this software update will restore supercharging to those people too.

He couldn't offer any prediction about when the part will be available,but mentioned that the part is in queue to be manufactured and is registered only to my truck. Appointment rescheduled for mid May, but that might just be a standard unknown timing extension.

do we only get the update if out pcs starts to fail?

Go to specs and warranty and see if you have free supercharging until July.

FYI Grok says:
This is an accurate summary of a real, widespread issue affecting many early Cybertrucks (especially 2024–early 2025 builds).

The symptoms, diagnostic codes (PCS2_a094, PCS2_a095, PCS2_a137, HV DC overcurrent trips), invasive repair process, warranty coverage details, recent goodwill pricing drop to ~$1,000 out-of-warranty, parts shortages/backlogs, and the social-media-reported service-center comment about the “first 75,000” trucks all match multiple owner reports, forum threads, and recent articles from the past few days.

Quick owner checklist (what actually helps right now)

• Check Service Mode yourself (Controls → Service → Alerts). Look specifically for anything with “PCS,” “PCS2,” “Power Conversion,” or the exact codes above. Early warnings often show up here before the truck fully bricks AC charging.
  
  
• AC home charging fails first (48 A → 24 A → “AC Charging Unavailable”), but the truck can usually still drive normally and accept DC Supercharging. PowerShare (V2L/V2H) also throws errors when it’s dying.
  
  
• Tesla is replacing the PCS2 unit + wiring harness with the latest revision (often called Rev G / T2-G) under the 4-year/50,000-mile Basic Vehicle Limited Warranty. No cost if you’re still in that window.
  
  
• For trucks already out of warranty, Tesla has quietly dropped the out-of-warranty “customer-pay” price to a flat ~$970–$1,000 (parts + labor) as a goodwill adjustment. That’s a big reduction from the earlier $5,000–$7,200 quotes.
  
  
• Parts are back-ordered at many service centers right now. Owners are reporting multi-week (sometimes 2+ week) delays and multiple rescheduled pickup dates.
  
  Is it a recall?Not yet for the PCS itself. There was a separate recall for early drive inverters on a small batch of 2024 trucks, but the PCS2 issue is currently being handled case-by-case via warranty/goodwill rather than a formal NHTSA recall or TSB sent to all owners.

Several outlets and owners are openly calling for Tesla to issue a recall because of the failure rate and the deep labor involved.Bottom line for owners If you’re seeing any of the symptoms you listed, open a service request in the Tesla app today and mention the exact codes if you have them. Early intervention can sometimes get you a loaner faster. The truck isn’t “dead” — it just loses convenient home AC charging until the PCS is swapped.Tesla has been covering these under warranty and is now offering the lower goodwill price even on some out-of-warranty trucks, which is better than the original quotes. Still, the fact that it’s hitting enough vehicles to cause visible parts shortages and service-center chatter about the first ~75k units is frustrating for owners.If your truck is still under warranty and you’re not seeing symptoms yet, there’s no need to panic — just monitor Service Mode. Newer 2026+ Cybertrucks also got an extended 7-year/70k-mile ZEV powertrain warranty that explicitly lists the PCS, which should help future buyers.

Thank you! I really do appreciate this post. I went into my service notifications and low and behold i saw a pcs2_a094 alert from last week. The issue is i messaged my closest SC in Orlando and they said unless im having issues with my truck they cant do anything. Regardless i still created a service for cleaning my camera view and i'll talk to someone in person about this. Through their messages its always a hit or miss. Btw AWD nonFS Nov2024 build.

Second update: second service advisor who was signing me out said PCS is backordered but, get this, they would create a new service appointment for me so I can proactively get the PCS done as soon as parts become available. She said they have quite a few Cybertrucks around the lot waiting on parts.

As for the cant rails, fitment is good but someone swirl scratched the heck out of the driver's side one. I mentioned it and they've ordered a new part. DIdn't even ask to see the pictures or to walk out to the truck and take a look.

Maybe by the time all the parts come in I can get a Roadster loaner!

Tesla added free supercharging to my truck until July 20th.

Is yours a newer model, and it’s had a PCS failure? I noticed yours is called a premium all wheel drive. Mine is called Cybertruck all wheel drive.

sounds like these are dropping like flies hope mine goes while still under warranty! No known issues yet vin 43xxx, 26k miles

Maybe there is a correlation with Supercharger V4 or something that is causing this instead of software. For the folks without pCS failures, how often do you guys supercharge?

that's an important question. trying to discern if it safe to use my free supercharging and go on road trip in July, VIN 071,XXX, purchased august 2025, only supercharged 3 to 4 times

My experience would suggest not, as we’ve done 45,000 miles in 16 months and 99% of it, has been done with super-charging. As of now, we haven’t yet had the dreaded failure… knock on steel!

I learned hardware first. My first computer used discrete resistor transistor logic, and needed repairs before I could learn to program.

Dad Gum man, you must be as old as me. I was a TTL guy 7400 series, never did any CMOS let alone MOSFET. woke up last night thinking I better look up what MOSFET is all about and why.

Yep, as a kid the most readily available PC was the HeathKit lol. I understood the basics of logic circuits, but not of electronic design, so I waited to get a computer pre-assembled (IBM 5150). Been banging on keyboards ever since.

I love it that this board is full of electrical/electronic guys that know a thing or two about things.

I tell my age by saying I was a distraught preschooler when they didn't show the Apollo 13 launch live on TV. I first wielded a soldering iron when I was 8. TTL was already a thing. I quickly rebuilt that first computer in TTL logic versus the discrete components on cards it was originally implemented in. The savings in electricity justified the expense. Plus I learned CPU design. In the years after I'd use many logic families, and branch out into analog circuits and computing.

MOSFETs... I now just call all similar Field Effect Transistors FETs. There have been many types over the decades. I think my favorits are the HEXFETs.
