Fails to charge on SC or at home

[bluerice]

My truck stopped accepting any charge and threw a dozen or so error messages. Tesla replaced
POWER CONVERSION SYSTEM - 48AMP(1777777-T2-G). Labor was (only) 15 minutes according to invoice.

I hope this isn’t a common issue as this could easily leave me stranded on the road. Has anyone else experienced this?

PCS failure is not that uncommon. It's the heart of an EV and is heavily loaded, so any of the electronic components that are drifting out of spec will cause it to misbehave and fail. It's located inside the HV pack.

There is zero chance they completed the repair in 15 minutes, unless they simply gave you a different truck.

The HV pack must be completely disconnected, including the coolant. And the PCS is accessed from the top, so the tonneau, bed floor, and air suspension must all be removed.

The Service Guide lists the procedure time as "4.20" hours, but IDK if they're trying to be funny.

They had the car for a week or so. The invoice is odd about the noted labor hours but it’s warranty so not concerned. Maybe when it happens out of warranty I can show them their own papers.

car has less than 1k miles and nothing non oem connected to it. Guess it’s just bad luck. Huge fail to not have a rechargeable battery so hopefully a one time thing.

bluerice, you have the latest version of the PCS installed.

What is the age of your CT?
Mine is 87xx, I just had mine replaced last month. Hopefully the latest PCS version fixes this issue.

2024. Also 87xx. How do I confirm the pcs version?

Just so people know, the PCS is a solid state electronic module. A properly manufactured one should last the lifetime of the vehicle and it is a system critical component. They do not wear out. If it fails its because of a manufacturing defect. Document and report every electrical/infotainment glitch with your trucks cuz when the pcs fails its mot a cheap repair, or one you can do in your driveway. Push tesla to test the mid voltage and low voltage systems when there is any electrical glitch, because after 50k miles or 4 years, they wont cover the repair, even if its a mfg defect

I must be special, because between the 5 Tesla we have owned (four currently), Tesla routinely covers things under goodwill, they rarely bill me, even when I expect to pay (because it's something I damaged). Of course, I think I haven't been to Tesla service for well over two years except to get the Cybertruck Winter tire/wheel set over a year ago. They also replaced my wiper motor and controller while I was there. No charge, of course.

This is something that really pisses me off about Tesla service. Whether or not a repair or replacement gets billed as warranty, Goodwill, or customer pay or even done is completely subjective. For example, Ive gone to service centers about the alignment/flush of my doors, the first one said “within spec, no adjustment needed”, the second said “not within spec, adjusted to within spec”. this is not just in my experience either, many have made similar statements on experiences.
Additionally, even when there is a very specific service bulletin for a problem, how the repair gets done is also completely dependent on whoever happens to be working on your truck that day.

Trust me, I’ve experienced circumstances like yours as well, where they fix something and call it Goodwill or warranty that I was completely not expecting. It seems, however that if you get on their nerves, or ask them twice about a problem, or question them, they turn completely hostile as if somehow they can never be incorrect. They then throw in correction codes like “normal characteristics” “within specifications” “educated customer” try to turn it back on the customer to avoid liability, and will start charging “diagnostic fees” when they in fact they already made warranty repairs that didnt work!

In October, my CT wouldn't charge from my home charger but would accept a charge from a supercharger. I took it into the SC and they replaced the Ancilliary Device Cluster Assembly, which solved the issue. They had to order the part and it took a week to get in the part and repair the CT. I was given a loaner Model X for the week, which I really appreciated, since I needed to haul the grandkids around at times.

I asked if this was a common issue with the CT and the SC rep said they had only seen this issue a couple of times. Just thought I would share the expericence.

Subjectiveness is just as common, if not more so, at traditional auto dealerships. But instead of deciding if they should bill you anything, it's more often whether they will bill you at a high price or expand the scope of the needed work and bill you an extra arm or leg. It's generally about increasing the revenue as much as possible. Of course there is subjectiveness involved at Tesla also, but the system is not designed to extract money, it's designed to only do the minimum necessary for the car to be a great and cost-effective car. There will always be a grey area whether a particular noise is a problem or not, but the guiding principles are whether the slight variation identified is a known problem or not. In the end they are trained to do what's right (but the system is only as good as those hired to do the hard work).

Same part number as the one you listed on your invoice.

I agree that their guiding principles include limiting expense… hence solutions like glue and tape. Statements like “the best part is no part” can also be extrapolated to “the best intervention is no intervention” using that same logic.
The fact is though that people wouldn't waste their own valuable time in good faith wait weeks for an appointment, drive in some cases over an hour, pay tolls, leave their very expensive cars for days if they didn't genuinely think there was a problem.
Its incredibly frustrating to go through that for them in some cases to not even look at your concern and return the vehicle with a vague correction code like “normal characteristic” or “within spec” when the customer sees others, or goes to another sc,, or even goes on a different day, and receives adequate correction or repair. Sometimes as simple as adjusted trim, added felt tape or nvh foam. What is the goal at this point? Save a few dollars for the trillion dollar company at the expense of customer satisfaction or doing whats right by the customer that spent $80-$100k+ with your company who will likely be insistent anyway? Seems like a no brainer to me.
