PCS Failure - Can’t charge at all

[webspeedracer]

I’m sure they fixed the problem with the PCs. I can’t imagine they would want to do this again. Besides that would open them up to lemon law issues. I still think every CT owners bombarding the service department asking for this to be replaced immediately might lead to a voluntary recall. If there’s a recall everyone can wait knowing it will be fixed for free when it happens. No need to rush. But the way it is now, you can’t take that chance or you could be paying $4000 cause it happened out of warranty

Your car is still probably still under warranty. It's really upsetting because my car is under 2 yrs old. I picked it up 3/31/24. I just drive a lot. I really like everything about Tesla and everything that Musk invents. I just don't like the way that this is playing out knowing that they have a faulty part, but they're going to replace only for who they have to for and not make the situation right. And it's really us, the early customers that took the risks and put the trucks on the streets and had to deal with the bugs. I guess we'll see what happens soon. I'm supposed to pick up my truck on Monday, Feb. 2. I've requested that they escalate my situation. The tech said he will, but he didn't sound very optimistic. Will let everyone know.

I’m in your same boat, picked up 3/16/24 and drive a lot. I’ve been driving my truck as little ans possible over the last several months, but now only a few hundred miles left in the warranty. My PCS hasn’t failed yet but I’m nervous since one symptomatic power failure while driving on the freeway in mid-October. My SC has always been great, but still concerned they wouldn’t be able to advocate for me under the current company policy.

Another 24amp limited charging here at 17k. What’s interesting is I made appointment and they automatically included in the notes to replace the PCS(2).

Add me to the list. Limited to 24amps. Service menu errors. 15k miles

More and more people coming forth, this is definitely widespread.. Wondering when I'm on the pecking order.

I think it's a matter of when will it happen for everyone. I've been following this issue for a while. Luckily I'm well within my warranty but this failure rate is unacceptable and should be fixed regardless of mileage

Early foundation owner here. Yesterday I got a bunch of errors including the 48 volt system. I was out of town so I was using the supercharger network. After charging and parking the truck for the night I tried to leave the next day and got many errors. I had to have Tesla roadside tow it to the nearest Tesla dealership. 41k miles on the truck. Should be all under warranty. I'm waiting for Tesla service center to open so I can contact them. But I'm wondering if the latest software update bricked our trucks. Because I just updated the truck before I left for out of town.

Coincidence

You might have missed not getting max charging speed at SCs over some time, it’s a slow degradation, errors piling up in the service menu
Once repaired, dig into the repair details and show is which PCS rev they install
Everyone seems to be getting, as I did,
PCS-…-G
Rev G

Repair is quick, I’m happy now getting 325kw

I believe the last supercharging session I was getting a full 325 KW. I'm just hoping they replace it anyways since it is there for service. Because I'm getting close to the 50k warranty.

Late to the thread here, but as of last night 2/15/2026, my FS CT from May 2024 has only started charging up to 24amps max. Seems like a very common issue for everyone on here, and typically goes down to 24amps before fully failing? DC charging is fully fine still? If fully fails can you not even drive?

Thanks!

Actually. I did get the reduced charging at home during the summer months. I live in Arizona as it gets super hot in here I thought it was related to that. But I called Tesla they thought it was the wall charger and sent me all a new wall charger. I haven't installed the new wall charger yet. So this could definitely be the PCS happening along with the 48 volt system. I'm just hoping that Tesla will replace the PCS as well.

Can you guys include your VIN ranges? I’m at 49750 miles, only one (serious) power anomaly while driving, no charging anomalies yet, VIN 3xxx March 2024 delivery. Trying to discern how nervous I should be, love my truck.

yes affects AC charging also, typically non of us hawk over the AC charging rate, making sure we get 48 amps
you notice it more with DC charging as we all want the highest speed when mobile
regardless, take screen shots of the AC reduced rate
push them politely/hard for the PCS replacement
good luck

Kind of a depressing thread. Fun for keyboard experts but for the regular informed consumer it sucks. My take is that this whole mess had a very predictable outcome. When a product is built and supply chain agreements set based upon a run rate of 250,000-500,000/units yearly and the actual numbers 2 plus years later are short by 90% that's got to be a BIG problem.

I say this as someone who just ordered a 2026 DM and I had fallen for the very interesting engineering story behind the Cybertruck rather than the production reality. At the current build rates Tesla has little to no influence with the supply chain vendors to revise/replace components that were either poorly engineered or manufactured or both.

It could be said that the PCS failure rate is indicative of a logical but radical move to a 48V architecture in a 12V world. It has been said 48V is the future but that future depends upon wide adoption by supply chain vendors. Tesla discovered that with many 12V components still in play and due to vastly misjudged run rates, the subsequent supply chain issues could and should have been predicted.

With Cybertruck demand being +/- 10% of original projections, the entire picture of the suppliers seeing huge quantity drops in component orders would inevitably lead to quality drops as well. Many components for SBW and RWS were outsourced and imagine how those contractors look at this huge reduction in quantity of orders. Of course this issue applies to virtually all of the non-Tesla made components and even Tesla is re-purposing Cybertruck lines for other products.

The Model 3 and especially the Model Y sales numbers made everyone from Tesla to their suppliers happy. The grossly mis-judged sales numbers for the Cybertruck make me wonder how it could possibly continue as a viable product. It also gives me pause as to the wisdom of my CT order and my long term plan of ownership of that vehicle.

If my logic is not sound and/or my conclusions flawed, I'd love to hear why I should stay on the path to Cybertruck ownership. Right now, I risk only a $250 order fee.

I think you’re safe with your order, because your truck’s high-priced power systems will be covered under the new warranty, you’ll get the most-recent component revisions, and you will LOVE the truck. I’m considering a trade-in to a new CT to get that warranty and peace of mind. It’s a fantastic truck and I’ve had very few problems, tons of enjoyment in my ~50k miles. I also have a Rivian R1S and wouldn’t swap my CT for a R1T. The driving experience in the CT is far superior (although the Rivian feels better off-road than my CT).
To your point about small quantities of CTs denigrating supplier quality of PCS and other components, I would say it’s the opposite. I think Tesla is all-in on 48V for CyberTaxi, because it is required for robust redundant autosteering, likely needed for power systems on a Cybervan people mover, for the vehicles that serve Boring Company loops, etc, and recent comments indicate the think the CT platform bolsters Teslas autonomous platforms, too. I would bet that CyberTaxi will use an iteration of the PCS in our CTs, so there will be ample buying power and spare parts supply, and Tesla will also want to ensure this is a robust component across ~1m Robo/Cybertaxis. My two cents.

That is a well reasoned response to my buyers remorse story. I'll probably stay the course as long as my Model Y trade in and FSD transfer aren't impacted by a significant delay with the order. Thanks for the helpful counsel.

Oh and an edit was required as my cancellation fee(s) also include the"destination fee" of $1,995. Begs the old carpentry adage "measure twice, cut once".
