I scheduled service and received this. Maybe they do have a fix. Looks like hardware?

Thanks for sharing the update. I’m supposed to have this done next week as well. Glad to hear it might finally fix my car!

Got mine back today. Park assist appears to be working as intended. They also fixed a sticky charge port door, the front passenger door not closing properly and the steering wheel making a crackling sound when adjusted. They kept it overnight and gave me an early 2015 Model S P85D as a loaner. Unfortunately, they put it in speed limit mode so I couldn't try insane mode, and the thing was so old it only had 3G connectivity. The horror...

Got my car back today it ended up to be the firmware reflash to get it going again. Everything seems to be working again including NAP.
Here’s the note on the invoice.

Concern: Customer states that they are getting a Park Assist (alert is currently present)
Technician verified customer's concern is due to a known firmware bug which requires a manual reflash of the PARK ECU. Technicians reflashed the PARK ECU and performed a full firmware update and verified proper operation after repairs were completed.
Correction: General Diagnosis Correction: Firmware Update

I've never even got mine to work in the 3 years I've owned my Model 3. LOL

Thanks - I have an appointment tomorrow for the same issue and I just shared this information with my SC to help them diagnose.

 

[JW37195]

Just got my car back and no part replacement required. They did the re-flash procedure and firmware update as others have noted and it's now working correctly. Here are the technician notes from the invoice:

Concern: Customer States: After receiving software update, I’m receiving the park assist unavailable message. Verified customers concern. Found park assist warning active after firmware update. Referenced internal documentation. Connected to vehicle CAN network and re-flashed Park controller inside VC right. Ran firmware. Test drove vehicle. Vehicle is now operating as expected.

   Order Date: July 7, 2021

Just wanted to share my AC stopped working yesterday. The app throws an error if I try to turn on climate and the console displays system fault when trying to turn on AC. Not sure if all related but I updated service request with new info - waiting for a response so.

Model X 2021 on 2021.4.18.2, Netherlands. Same problem. Intermittent notification, even on the freeway. Reboot makes no difference. Will make service appointment and see what happens.

UPDATE: Tesla diagnosed faulty microSD card. Replaced. Problem went away for a few weeks then returned last weekend. Back to service today - they could not find any fault or reproduce the error. They said it is likely a software issue. They added and that there have been reports of the same in the US and Tesla working on a fix but with no timeline available.

I just had mobile service yesterday replace the passenger side controller and then reflash my firmware. It's interesting that some people have reported that reflashing the controller was all that needed to be done. If that is the case, all the work replacing the controller might not have been necessary. From start to finish, they spent nearly 2 hors getting the replacement done. Fortunately, my 2018 RWD M3 was under warranty.

As an aside, I asked if they could fix my driver's seat that loudly squeaked as it elevated. No, they said, but they are ordering me a new seat. Concerned that new seats no longer have adjustable lumbar support, I wasn't sure I wanted a replacement. However, they assured me they could transfer the lumbar support from the old seat into the new one.

My 5 week old M3LR has lumbar adjustable seats.

My 5 week old M3LR has lumbar adjustable seats.

It was removed in the Model Y passenger side (along with the radar) with the recent models. Are you saying your passenger side has lumbar controls also?

2020 Model X this just appeared on a long trip to California. The message pops up while driving on the highway.

PS it's very annoying that these things appear under certain car models (not mine!) on TMC. How to find anything???

Usually the "park assist not available" message appears only when you slowing down below 5 mph. I am surprised it appears when you are at highway speeds. Perhaps, on your newer car, there is a different underlying cause than what has been reported here in this thread.

Hi there!

Got the same problem with my 2018 TM3 LR AWD: Parking Assist Unavailable. There is no "parking waves" in front and behind the car on the display while driving. Also zero parking sensors are vibing when i`m physically touching them. Car's FW is 2021.4.18.2.

I don't have an ability to visit SC, car has been used at officially unsupported territory. Maybe someone knows how to reflash PARK ECU or where to search for the exact information? I`ve got a cable to connect directly with car's gateway and toolbox service account access.

Thanks a lot!

You are correct, only the driver seat has lumbar controls.

I have a 2021 Model X with a December 2020 build date on 2021.4.18.3 with the same issue.

Well, this problem extends to more than parking unfortunately. it means NAP doesn’t work, the chimes you get when pulling Into a tight spot or garage don’t work, warnings for cars that are too close when driving on multi-lane roads. The error just happens to be for Park Assist. Also, think about what you said, the Park Assist feature is as good or better than any manufacturer out there IMO and the point that it hasn’t been updated in 2.5 years is simply something that most other manufacturers don’t do. Ever. We are #TeslaSpoiled

Ahh. This is what I was looking for. Same issues that I’ve been having over the last month + where it was one of the June software updates that knocked everything out of whack. They said that the firmware update upcoming should resolve it. Got one last week and it was just for a new game. It was the latest that’s available. So I guess will have to see if my local service center can pin this one down.

Do you know if there’s a specific TSB or something on this?

 

[SUP THO]

I've had the "Parking Assist Unavailable" pop up over the past few months on my 2020 model X. Took it to the service center and they kept the car for 3 days and said they weren't able to replicate.

I'm curious if anyone has a Metromile that plugs into their OBD port? I noticed this it happens more when it is on there, and for a few trips after it's taken off. I also cleaned the front and rear bumper sensors and noticed the alerts have been less frequent over the past few days.
