NEW PCS (Power Conversion System) Failure & Replacement News

[Jabman]

I made my first appointment for the PCS failure on March 27th, scheduled for April 23rd. Part wasn't delivered so rescheduled to May 28th. Part still not delivered so rescheduled to June 22nd. Communications today revealed that the part still isn't delivered and it doesn't seem like anyone knows when it will be or where I am in the parts queue, or even if there is a parts queue. Has anyone been waiting for more than 3 months for this repair?

What frustrates me is that I'm reading about some people waiting only a few weeks and getting a repair. Also new vehicles being pushed out, but I'm waiting for three months for a part in a vehicle actively in production with no communication other than my monthly reschedule?

I’m going on 2 months. I’m hoping the revised part is the permanent fix and this is the last time I have to deal with this

I know someone got bumped up in queue (assuming there is one) and got it back in a little over 3 weeks. Their truck was dead on the side of the road. It had screens and AC/heat but it wouldn't even go into gear.
He also had to get a rental from Tesla so I think that probably had something to do with it.

Mine was just pushed from this week to August. They asked if my truck could run and I said yes and then said they would need to push it out for more serious PCS replacements.

Check for alerts under service mode. Partial failures may not show up on normal UI.
Also try charging at 48A.

WILCO. I charge at 30 amps but I'll check for partials in the morning.

The PCS failure mode hasn't produced safety issues. I'm not sure what you mean.

Tesla has been proactive. What else do you want them to do?

I know this is a few months late, but my first pcs failure (sept 2024) threw a critical alert issue, disabled rear steering, put it in limp mode (4mph), significantly reduced the power assistance to front steering, and threw alerts about potential loss of all power and braking. Only way I see it being a bigger safety issue would be if it burst into flames. Software updates may have helped minimize that type of failure, but no one can convince me a PCS failure is not safety related. I just lucked out I was on a 25 mph side street during the day when that happened and not traveling down a freeway at night.

That was a DCDC failure in the PCS. Charging is a DCAC failure. Two different functions in the same unit.
