We’re the same: about two weeks ago mine went to 24/24 at about 30k, FS AWD, May 2024 delivery.

With Tesla’s expertise with music and sound effects in their cars, maybe they can push an update to trigger the “whah, whah, whaaaaaaah” trombone sound when the PCS throws an error code, haha!!

Anybody know what wire that ferrite

Got mine replaced today. SC did it in one day. Dropped off at 7am, picked up at 4pm.

Anybody know what wire(s) that ferrite is placed around? That could be diagnostic for what is possibly causing the failure. Ferrites are used for filtering. Often for decreasing transient spikes.

How do we pull error codes from the service menu to see if there’s any PCS issues proactively. I know how to get into the service menu, but where do I go from there to look for codes specific to the PCS. I only supercharge exclusively so I don’t have any Evidence of even early PCS failure since I don’t level 2 charge.

also, someone mentioned that the PCS is covered on the 2026 cyber trucks?

I don’t believe that’s correct. All the warranty changes for 2026 with the new power system warranty exclude cyber truck so there’s no change to the PCS coverage as far as I understand please correct me if I’m wrong.

My foundation series only has 9200 miles but now I'm getting worried..

We are all beta testers, my friends like it or not

It reminds me of this really hot girl I dated in my 20s who was always having fucking breakdowns, but the body was absolutely amazing and she was great in bed.

Most exhausting yet at the same time, exhilarating relationship of my life.

Just had mine replaced. Foundation Beast VIN 27xxx with 29k miles. Randomly noticed charging at 24/24 at home vs. 48/48. Checked service mode and there it was. Mine was for unhealthy DC tank.
Made service appointment in app and it was two weeks out. The next morning they messaged me and moved the appointment up to next day. Dropped it off on a Thursday morning and picked it up fixed on a Friday afternoon.
Basically, Tesla got me in two days after I requested service, gave me a loaner, and fixed it in a day after drop off for free. YMMV, but I think I’ve got a killer service team nearby.

***-Yes you have a GREAT local service team!...we have TWO SC in our city...and it has gone from 4 weeks to 2 weeks for service..My PCS Alert today...VIN 69XX; 43LK miles 2024 FS AWD. GROK suggest that Tesla not only replace PCS , but Power Inverter too! (PCS convert AC from Home to DC for the Battery; While power inverters converts DC to AC for the motors)

If it handles propulsion, then why isn't the part covered under the battery and powertrain warranty?

I would be leaning heavily on reported electrical issues that were discovered prior to the warranty expiration.

I agree, as a first edition vehicle, they should take care of the issue under warranty and customer good will. However, Tesla demonstrates little interest in 'Goodwill' once the purchase has been made.

Instead Tesla is going to play 'wrong rock' i.e. the charging systems is not part of the power train.

I would definitely talk to a lemon attorney. Also, if you can get all the historical error logs for the vehicle - to see if there was a error earlier on the Tesla did not act on.

I have 30k miles on my Foundation and just had the PSC fail & replaced. Of late, it has been in the back of my mind to sell it before the warranty is out.

From my experience with Mercedes and a $13k repair bill for a bad tank of gas in a G63 I'd had - in which Mercedes covered it completely, we had an initial discussion about it not being warranty, [It was under warranty] however, we fairly discussed that the fuel filter should have protected or clogged, not propagate into all the fuel injectors. They earned my loyalty.

Tesla enjoys a 'remoteness' via chats in apps, where no one your talking to is the actual decision maker.

Maybe it's the tone you are using with the Tesla personnel? I have had the opposite experience.

same here
I bring gifts to the Tesla team with every visit
Created an atmosphere of cooperation
We are amicable toward each other
I’ve complemented their amazing customer treatment

if out of warranty, no idea
All works been in

Small update on my truck, after scheduling in the app on saturday morning for the first available time which was April 6th, I texted in app this morning asking them to take a look and see if I could get in earlier. They messaged back within a few minutes letting me know to drop it off today and they'd have a loaner waiting.

Parts should be in tomorrow morning and they think the work will be done tomorrow or wednesday.

Side note (I wish I had setup some sort of automation to detect this) I looked back at my charging history on Teslamate (I charge almost exclusively at home) and noticed that on February 28th my charge rate had dropped from the normal 48v (~11 kW) down to 24v (~5.5 kW). That would have been a great indicator that things were going south.

It is hard to have a tone, via app chats. I am used to person-to-person.

Any reasonable person would be perturbed if a confirmed tow request was cancelled. Few think it's safe to be broken down in or on the roadside.

Many I know have gone to assist friends and family when broken down. It's a standard in our car culture to appreciate that breaking down incorporates an element of trama.

I do approach these things with calm and allow the provider set the tone. I will respond 'firmly' not confrontational to those issues where I feel it's is not equitable.

Goodwill: Here is a photo of my CT windshield after the PSC repair. I did NOT run the wiper - someone at Tesla service did.

Leaving and allowing the car to get dirty is one concern. Turning on the wiper on that vast expanse of glass is bordering neglect.

It does not convey 'Goodwill' from Tesla.

This is what I had to look thru on my drive home from PSC service. I did not post this in my initial PSC repair post - as I don't want to dogpile.

I held this back as to not dilute my story in that post - which was only about the PSC and my mileage of occurrence, and IMO it is safer to get it towed.
