PCS Failure - Can’t charge at all

[Jhodgesatmb]

I am saying it is not an issue The National Highway Traffic Safety Administration deals with. The failure mode is akin to running out of gas with a working fuel gauge due to your fuel door not opening versus having your fuel pump suddenly fail while doing 70 on the freeway.



The other two agencies I listed may care more.

I am not a lawyer either but maybe something like this, if the NHTSA doesn't care, should be addressed in the legal system.

I guess I don't see a difference between you having your fuel pump fail at 70 and your car stopping because you ran out of gas in the middle of nowhere. You're still screwed and that is a safety issue. It may be true that the NHTSA won't care but I submitted a complaint anyway.

How are you running out of gas in the middle of nowhere? At the least, you should be running out at a gas or charging station.

A suddenly failed fuel pump has no warning and with older cars takes the power steering and power brakes with it along with propulsion.

Sure, and that would be a product warranty type issue which other agencies deal with such as implied vs express warranty and state level protections.

i was just using an ICE car as a comparison. If I were on a trip and my truck suddenly told me that I couldn't AC charge (and, as I found out. I couldn't DC charge either) I'd be screwed. Most of my road trips are in the winter so I'd freeze to death unless highway patrol happened along. All I am saying is that I 'do' consider this a safety issue.

I'm not disagreeing with it being hazardous, but the failure mode doesn't impact highway safety. To get traction, you need to send your concern to the appropriate agency. Otherwise, you may just be spending effort for no result along with not acting further because you think it was reported.

Example: a power tool with bad insulation can kill you, but it's not an FDA issue.

And now I've completely lost AC charging before my scheduled appointment on Thursday. I have 150 miles to the service center, I'm requesting a flatbed because I'm not getting stuck mid journey

FYI, I put in a service request to ask about them preemptively replacing PCS modules for early adopters. Since it seems like one user reported them proactively doing it for them without asking for it + all the other issues.

I asked considering the increasing amount of failures with earlier models.

They responded: "If you are not having any issues with the PCS as in alerts or charging issues this does not have to be serviced at this time."

I tried to push and mentioned the experiences here... which lead me to believe its a known/widespread issue (including the preemptive replacement )

They responded: "We can add it to your ticket if you are requesting that. We don't automatically add it in case someone is not under warranty. I have added it to your ticket."

"Ok, ty, so will that replacement be covered under warranty?

They responded: "yes"

The appointment status then switched from "in review" to "part in transit"

I reached out the next day and asked about a timeframe and if a loaner would be made available.

Someone new responded:
"Good Evening, we sincerely apologize for any confusion caused by our previous communication. We would like to clarify that vehicles requiring PCS replacement will have a specific bulletin or engineering work order linked to their VIN. As this vehicle is not currently flagged for a PCS replacement, we are unable to proceed with a proactive replacement unless an issue is present. Please don't hesitate to reach out if you have further questions or concerns."

Anyways, I found this interesting. Now im wondering if it's all BS or there are truly a series of known VINs.

I get that the warranty SHOULD cover but if this really is a major issue... I don't like the fact that I am basically left to roll the dice and could potentially be left stranded / unable to charge while on a road trip. Covered or not. Big selling point of a tesla is the lack of maintenance but if you could get stuck with a $7k PCS repair bill at 50k+ miles... that's more than you'd have to deal with on a gas car.

Interesting. Sounds like they identified a certain VIN range for the PCS failures. But aren’t doing an actual recall.

Does charging at Superchargers avoid stress on the PCS?

Supercharging does not use the PCS DCAC converters .
AC charging, Powershare, and the bed/ cabin outlets do.

ok great im wondering about my truck. No PCS problem yet but im Vin 1955 so pretty early one.

great point
What’s the earliest vin with a PCS replacement? Assuming before that no pcs issues

Maybe few but, bean counters had the original good PCS revised for lower cost and then the failures started
Then revision -G, where we are at is a good PCS again

Will be interesting to see how high the vins go with no PCS issues

I'm a VIN 13,900 and PCS failed. Appointment to replace March 6.

Tesla should have added to the Foundation Monroney sticker. A 1 in 9 chance as an example ya get stuck with a $6000 bill between 50-and 75k in miles.

I understand for newer versions PCS is under a better warranty. 10% of the cost of the truck for the new cheaper AWD for replacement. Just something to ponder upon purchase.

I haven't read through the post yet, but dropped mine off today for the PCS. This weekend my charging dropped to 24A at home on both of my wall chargers. 30k miles on the truck, bought July 2024, AWD FS. So far this is the first issue I have had with both my truck or my wife's M3. Hopefully it's the last....

Hold my beer. After asking for the truck to be towed as I had limited charge at home I was told by Tesla roadside that I had enough miles to get to the SC and that I could supercharge. On the way there with about 20% left I decided to try supercharging so that the vehicle wasn't left at the service center with a low state of charge. Low and behold the truck would not supercharge and I arrived at the service center with 7% remaining while it's going to wait for parts to arrive.

interesting. Wonder why? I guess after failure then it might not supercharge.
