Tesla pushing update failed PCS to enable supercharging while awaiting PCS repair part

[dalton108]

My honest feelings exactly right now. But I’m like do I really need it lol.

The answer is yes. You really do need it!!!

My current timeline since I dropped it off on the 10th. What’s crazy is it seems like we all failed at roughly the same time to make me think maybe an update was the cause. But who knows.

I'm hoping the PCS in my Cybertruck doesn't die, ever. The reports I've seen suggest the failure rate will be well below 50%. Any vehicle can become inoperative, PCS failure, especially with Tesla's idea to push software updates that keep DCFC alive, falls far short of leaving the vehicle stranded. I'm not worried but, if I'm unlucky and it happens, I will deal with it in a pragmatic manner, not fall to pieces.

The fact that Supercharging will be free for anyone having to Supercharge until the part is available is commendable customer service, and the right thing to do, saving affected owners the cost of home charging for their inconvenience. Not a big deal for me in Washington but really nice for those in areas where residential electricity is over $0.30/kWh! I can't imagine GM or Ford sending a timely OTA update this quickly, assuming they could even do that. Tesla has responsiveness that puts other automakers to shame. You should stop by some GM EV forums and see how GM responds to design defects, software defects, and general reliability/useability issues.

Kudo's to Tesla's pro-active response to taking care of their customers, and doing everything within their power to minimize any hardship for those who are affected.

Interesting claim about the percentage. It seems that just about everyone here that has an FS has had it happen. That said, even if the percentage is below 20% it is a large enough number to warrant a recall.

So the under 50% ultimate failure rate is just your WAG?

Yep, that's all people on the outside can do with what we have (the people proclaiming that ALL PCS will fail on early Cybertrucks are just making WAG's too). Given the visible failure rate to date, I don't find their WAG's as credible as mine. Some people are even claiming that just about ALL FS Cybertrucks have ALREADY had failures. That's pushing a false narrative.

Where is this VIN specific list narrative coming from?

I recall Tesla telling some owners who thought it was a good idea to replace their PCS pro-actively that their VIN number wasn't in one of the ranges that Tesla was concerned about. If I'm thinking of something else, let me know because I obviously have not made following this a significant portion of my life. Components fail, not worried about it, especially since it doesn't leave the vehicle stranded in the back-country.

I don't think "just about everyone here that has a Foundation Series" means what you think it means!

Are you accounting for people like me who haven't had a PCS failure and don't repeatedly make new posts highlighting their PCS failure? Many people have posted over 20 times each on this very topic! A few people have posted a lot more than that, in the triple digits (but I'm not naming names).

I actually feel sorry for people who, like me, haven't had any PCS failure but, unlike me, who have let it become one of the most relevant things in their life even though there is literally nothing they can do about it and, even if it actually happens at a future date, it likely will cost minimum time and effort. The "fix" Tesla has implemented until they can get the required parts to fix the problem is very commendable and Tesla Service Centers will only become faster and more proficient at installing the new part. To me, it's a big nothingburger. If my PCS fails, it fails. I can't do anything about it. At least I can still access Superchargers and continue to drive the truck. I already drive by multiple Superchargers every week that I never use.

There are far too many people being overly dramatic and making irresponsible statements (like just about everyone with an FS has already had their PCS fail).

Sure it's not all, mine May 2024 FS Beast is still rocking the original PCS. However, I did get this alert last night:

Ah, I think that list is Tesla's mothership tracking alerts from vehicles, not a list formed from the manufacturing tracking data. Or a result of someone asking for their truck to be fixed due to "the recall" which doesn't (yet?) exist.

It could leave one stranded in the back country if they were driving to the backcountry where there was only AC charging and had it suddenly fail. Low occurrence, but valid for boondocking/ overlander types. Or people that live far from DC charging and have one vehicle.

Wow I didn’t know this was a widespread issue . I just had this happen to me last week. I woke up unplugged my truck and it said ac charging unavailable .

That happened to me about 10 days ago. It’s with my local Tesla service center. Thankfully I was able to get a loaner since they don’t know when they’ll get the part in.

Under 2,000 VIN FS AWD, under 20,000 miles, no issues so far...

 

[shurley1975]

24xxx vin FS, 12k. No pcs issue YET.

When my PCS failed and stopped taking a charge on my home charger I contacted service and they said it a probably still be charged on super chargers…. It would not take a charge. They took it right in.

Then after when my mid-voltage backbone harness when out, not only did the screen go crazy with warnings and telling me to pull over losing all power and going brick, the rear drive locked up and required a flat bed to take it to service. It is scheduled to picked up today. The way service worded the problem it appears to be still related to the PCS.

Both could have left me stranded big time if they happened on my recent 1,000 mile trip Fl to Tx.

I wonder if this had anything to do with my problem…..

Wow!!! Your wheels remind me so much of the back to the future dolerean almost an exact copy .

Re-enables DC fast charging. Free Supercharging while AC charging is inoperative.

Mongo, who is Kyle Field and why should we trust this information?

Plus confirmation bias. I had previously asked Tesla why the PCS was blocking DC charging when the HVDC bus was still functional.

And people wonder why Tesla is building their own Fab plant (TERRAFAB). Asia owns that market and disruption is going to be more common. A lot of folks here complain about Tesla but for perspective, they should spend a little time on the Rivian and if you really want a wake up call, Lucid Forums. Tesla's service is the gold standard by comparison. Lucids are being broken by bug ridden OTA's regularly and their fleet is tiny by comparison. Tesla does most things really well and this PCS issue is an good example of being responsible and keeping the wheels on the bus until full resolution.

I guess being a 2026 CT owner gives me a more comfortable vantage point but despite all Tesla's being born from a lean design perspective (best part is no part) they are actually very complex machines with many systems to manage. Tesla is doing that management better than anyone ... IMHO
