PCS failure rates by year...is it just a matter of time?

[Black306]

To have any idea what our chances are, we need someone with a replaced PCS to mail the failed unit to Munro

If someone is paying for the repair, they can request the old part. IMO, it would be good to get a failed PCS into the hands of someone that does component level repairs to find out what’s failing.

I have 30K on my 2024 FS AWD and had the PCS fail a week ago and replaced and got my truck back yesterday. They told me it is a new part. It is the only failure I have experienced beyond my wiper. I would think that trading in for a new truck or buying a used truck would present other risks so I am inclined to keep my truck. That said, I am hoping that the powers that be will force Tesla to recall this part and force them to solve the problem. I also believe that this should be included in the power train warranty but that is just me.

I should that when I got the error that I couldn’t use AC charging I had 50% SOC but I live 20 miles from any SCs so we tried going to an SC (the app suggested that would work) before going home but that didn’t work. So I basically didn’t go anywhere until I got a repair appointment which, luckily for me, they prioritized because when I first booked an appointment it was 3 weeks out. So yes, I was scared but I’d have felt much worse had I been out on the road somewhere.

You basically described my situation. "AC Charging Failure" this past Sunday, two days ago. 25K on my 2024 AWD. Drove to the SuperCharger 13 miles away, yesterday (Monday), didn't work either. Earliest appointment available next Tuesday, 60+ miles away. CT is parked in low power mode hoping I have enough charge to make it. Glad it failed under warrantee, but very inconvenient since this is my work truck with all my tools on board.

Hi all,

I have a very early FS CT and have been loving it. With the ability to transfer the FSD to a new cybertuck, I'm very tempted to trade mine in for a new one. The trade in offer is higher than what I owe which is awesome (holding it's value really well). The main reason for wanting to update it to a new truck is to reset the trucks warranty while I still can transfer FSD and to get a truck with a newer PCS version (although these still can fail but the failure rate seems to be lower). My truck has 15000+ miles on it and I haven't had a PCS failure yet (I have had to deal with the various recalls and my inverter failed around 6k miles). I only have about 1.5 years left on the warranty that would cover the PCS failure, but mostly I don't like the idea of possibly being stranded because based on the various threads here it happens without warning and randomly. I absolutely love this truck and want to stick with it, but wondering what everyones thoughts are on trading a low VIN (700's) FS for a new 2026 model and transferring my FSD. Oh and not that this matters a bunch but my payment would also be $500 less a month.

Alternatively I'm eyeing a new model x which comes with the luxe package and is capable of towing our trailer (used to have a model x and it towed it fine). But I think giving up the CT would make me feel dead inside, so this option might not be feasible.

Feedback is appreciated!

I was considering the same idea. They have offered me a $67,700 trade in on my 2024 AWD (25K miles). But then this past Sunday my PCS failed. Scheduled to be fixed next Tuesday, so I guess I'm going to hold on to it, until I have a really compelling reason to replace it.

60k miles on my 2024 CT AWD. Haven't had an issue with this. Guess I'm beyond the mark

54,000 miles on my FS AWD and i can only charge at half speed on level 2 chargers. so it charges at 5Kw (instead of 10 or 11Kw) which is pretty slow. supercharging is normal i assume this is the PCS failure its inconvenient but not horrible i have an appt to repair at tesla in 4 weeks the estimate was $1,000
which seems low for a PCS i will post my final repair info

Seems ridiculous to be saying this, but I wish my PCS would just fail lol

Mine also charges at half speed on level 2 chargers and I do have an appointment for next week but not sure if they'll do anything. They try to tell me it's the wall connector, but it isn't (my other tesla's charge just fine). Maybe I'll get lucky and they'll just change the PCS during my appointment and then I'll keep the truck.

I have a 2024 CT with just over 48,000 miles. I’ve been driving it less because I’ve been afraid to go over the 50,000 and then have a failure of some sort. I noticed a few months ago that at home I couldn’t charge past 24 V. I thought it was the mobile connector or maybe the wall plug or power circuit itself. I had someone recently come over and they needed to top off a charge i’m there model Y while we ran some errands in my CT. They noticed they were charging quicker on my charge cable than they do on theirs at home. When I looked at their charge rate they were getting 48 V. This was a great test and let me know that it is not the charge cable or the circuit. I reached out to TESLA and created a service appointment. Service appointment is three weeks out, but at least I’m not having any actual problems charging. It’s just slower at home which hasn’t been an issue for me. When I stopped by the SC to talk about my appointment and I mentioned the 50,000 miles and the PCS issue, they told me the PCS is part of the battery and drivetrain warranty and would have still been covered under that 150,000 mile warranty.

That last part of last sentence is not correct.

What @Outdoors said.

I believe the PCS is now included in Tesla's 2026 High-Priced Propulsion warranty on the other models in Tesla's lineup, but is specifically excluded from the Cybertruck warranty.

Not that it would help pre-2026 CT owners, even if it were.

If you end up paying for a PCS, request the old parts! A simple teardown might reveal a fried component.

Mine just failed at 17k miles, FS CB. Same symptom, reduced AC charging soeed, not sure how long that occurred because I didn't really catch it at first, two of my chargers only charges at 24a anyway, the third is faster. In the shop now and I'm in a loaner. They also scheduled a bolt replacement from a different recall for this visit. If it is a design flaw rather than a quality control issue they will have to redesign the part rather than keep using it.



I haven't looked into it, but if there are enough failures I would expect a recall. Honda just did one for my UTV which is out of warranty, Ram did one for a diesel truck I had already sold after the warranty. Not sure what the threshold number would be but I've seen it on other vehicles with cash payouts to those who paid out of pocket. Manufacturers want to avoid a class action and bad press so the get proactive. Then again this is less a safety issue and more rendering the vehicle useless. Tesla has fumbled public opinion so often with this truck that I would hope a voluntary recall is preferred. Too many of these not to be a systematic failure.

My 2 year old Foundation with 28,000 miles had the PCS failure, it was towed in yesterday to Tesla Upland, CA.

Before the Error code, it was behaving oddly on the home charger : The app would show the charger current at 24A when my home charger is 48A. This oddity was new -as I've had the home charger for over 1 year without this odd - change of the current. I, like other attributed it to the latest software update - because why leave good things alone - when you can change 'for the sake of change'.

The error code: PSS2_a094 reports 'AC Charging' unavailable, offering that Supercharging is still functional.

It tried to Supercharge on 2 stations - it did not SuperCharge.
Also, it did not report any errors when the Supercharger connected - watching the screen like a hawk - I saw 'Starting Charge' then - it flipped back to 'Start Charging'.

So this issue is poorly handled by the charger & vehicle - as it does NOT show any error, only flips to 'Start Charge' and does nothing when you press the 'Start Charge' on the dash.

Tesla Roadside App :Disclaimer: I am a spoiled Mercedes owner
Tesla Roadside leaves much to be desired. My 1st request for a tow was cancelled by Tesla - as I did not engage in and in depth chat with the bot. The initial tow requested ask for errors and issues, and for me to confirm my location which I provided. Yet Tesla wanted me to engage in more chat dialog. Which being somewhat stranded - I was using my phone to report my lack of arriving and such to my co-workers.

After 10 mins I check the roadside app status: to find the tow was cancelled due to my 'lack of response'.

On the second request, they proposed I drive my CT 11 miles, with only 32 miles [~10%] range to the repair center. Which I informed them I am not comfortable driving on a major busy hwy at 2:30pm on a work day with a vehicle that - if it fails - will stop dead in the middle of the hwy.

My concern is escalated, when the dash error reports I can 'Supercharge' when I actually cannot, and the Supercharger/vehicle does not report any error - but refuses to start charging. [What else is wrong that I am not being prompted about]

Also the CT at 10% warns you to 'Charge ASAP' with quite intensity - not to keep driving. So the roadside tech and in vehicle protocols don't match well.

I prefer the option that puts me at the least physical risk.

Once at Tesla Service, they were quite open that the PSC will take a few days to get, and will require a few days to replace. I had to empty the entire bed and bed vault. Looking over at the Service procedure. They will be pulling nearly all the interior bed panel out to access the PCS. This also includes opening a part of the battery pack.

I can imaging that if out of warranty this would be a $10,000 repair. I easily see the PCS board alone costing about $4k, is is a high voltage and high current board - these things are expensive.

Tesla service provided a loaner and were kind about updating me.

I will report back what and when I get my CT back.

Regards
Jack

How many miles?

I was just stating what the service rep told me.
