Interesting. The wiring harness to the PCS but not the PCS itself? Hopefully it fixes it!

“Usually when we talk about self driving cars, its after a problem…this story is different” - saying the not so quiet part out loud..

Wow… 50+ PCS failures… that is shocking… this is not a small sample. I know it is relative to “every ct sold” but damn, one part in isolation failing this much in such a small group… genuinely curious what the actual number of failures has been.

You guys think that bumper is dirty or actually sun faded?

No, the old ones pop right off when lifted, the new ones snap right in place. No fasteners needed. The purchase includes shipping to SC of your choice and install though.

Interesting. Mine was replaced with 48AMP(1777777-12-E) back in April 2025. Maybe they updated the part? Wonder if E revisions were failing too, necessitating a subsequent F, then now G? Who knows…

Can you add it to the cart? You should be able to just buy it.

The EV pickup truck was a bold move any way you look at it. Tesla is very well known for shooting for the moon and ultimately just building a space station instead. The CT they build now is not the truck they advertised in 2019. It does some things REALLY well. It does other things that most...

I was driving home from work last night *on FSD* and experienced this. It was going through an intersection at almost 40 mph, a car about 2 car lengths behind me. The light was flashing red for me, flashing yellow for the other side, right when the truck hit the intersection it suddenly slammed...

i think youre right

You can adjust how reactive it is in the safety menu, changing it from early to late or off

Gyatt dang thats nuts. Wonder how long that would take to finish off a CT

What do they say the correction is? Should be in your estimate is? Should be in your service app.

unless some electrical engineer gets ahold of the failed pcs units and evaluates for a root cause, the public may never know why this is happening.

In isolation, no. But in combination with the other errors, something linking all of those systems along the 48v system is causing the faults. Could potentially trace back to the PCS. watching thread for sure

It will still be in service mode alert log

Ai says basically it could be from a number of things- essentially those systems are detecting instability in their power supply and throwing the critical faults. These should be priority for service evaluation. If this is the 3rd time this has been repaired, most states consider that a lemon...

Check service alerts in service mode. But yeah, schedule service

Don't ask me. If you think you should then go ahead.

The highest out of pocket price ive seen is around $7600. Others have reported less. This is not a component that is supposed to fail. It is not supposed to “wear out”. Its failing either because it was defectively manufactured (more likely) or defectively engineered.
