Power trunk retrofit causing car awake

[AZAV8R]

That's me - 2019 Model 3 out of warranty end of Sept 2023, and I had Tesla install the powered trunk retrofit in Oct 2023. I paid $1000 for Tesla to diagnose and replace VCFRONT to try to correct the HVAC issue but am I glad I found this thread! I was going to get Tesla to replace my blower motor but now I'll just sit tight and wait for the software fix. Tesla Toronto never told me my intermittent HVAC issue relates to my powered trunk retrofit.

I don’t know how far you’ll get, but ask them to refund your grand. They went on a fishing expedition at your expense!

You seem to be less upset about your misfortune than I am. I would be raising hell.

Has anyone is this situation installed 2024.3.20?

Have yet to get an update since the last time I posted in here for 2024.8.9

I installed it but still have it unplugged. I think i read somewhere (on this forum?) that this update didn't' solve the issue. May be in the 2024.12.XX ones.

Another update (2024.3.25) and another instance of trunk failing to open. Update was performed with trunk 2 wire cable disconnected. Power cycle fixes the problem. Very annoying

I am experiencing the same thing right now. How did you power cycle it? I sat in the car touching nothing for 4+ mins after tapping the power off button under Safety tab, but it didn’t help

Same as issue here, do not install 2024.3.25. Cannot open the trunk at all.

As hoped, letting it sleep for 6 hours fixed the issue while I was at work. Sleep does wonders doesn’t it? Too important to allow this issue to persist.

Low key wanna ask service center uninstall the power trunk and go back to manual for good

At some point my car stopped connecting to LTE at all, so now I can't even tell if it's sleeping or not because the wifi antenna on the car is so weak and the connection isn't strong.
But hey, I updated to 2024.3.25 after losing 10% of battery in a day.

Maybe what @AZAV8R said in his post Power trunk stopped working, then started working again!
would help? Charging to 80% with/and/or the car sleeping?

I'm guessing "power cycle" as in a soft reboot by holding down the steering wheel scroll wheels down simultaneously until the screen goes black...

I disconnect HV and 12v battery.

I looked it up and followed Tesla's instructions here, but it didn't work, or maybe I didn't do it long enough. Then I left the car sleeping for 6+ hours at work and came back to a working trunk again. "Sorted itself out" kind of fix.

I suppose the person you linked who got it fixed by charging to 80% had left sentry off and gotten the car to sleep after finishing charging, too. It might also just need an hour of sleep, I'm not sure.

I updated to 2024.3.25 and had left the cable disconnected, and after the update trunk failed to open. Parked at home, sentry off, let the car sleep and trunk worked again in the morning.

 

[FastGTR]

It works after a few hours of sleep, but the sleep only happens with the cable disconnected.

I can confirm that power cycle (Safety --> Power Off) with and without the cable connected did not resolve the issue. Disconnecting HV and 12V with and without connector disconnected did not help.

Wonder if something got pushed down as I was on the phone with Tesla support, and they acknowledged they were seeing reports of the issues.

I can also confirm that the cable connected it is still not sleeping.

What a cluster!

I upgraded my 2020 M3LR from 24.3.20 to 24.3.25 with the CAN cable connected, and the trunk controls continued to function. Unfortunately, error PCS_a022 started appearing after about 30 minutes, after a short sleep.

 

[justsomeguy]

In the other thread someone said they got a special firmware that fixed their issues, and that the version after 2024.3.25 should include it for all cars.

Model 3 powered trunk retrofit causing intermittent cabin climate control system failure Here's hoping!

I'm considering installing a power trunk retrofit on my 2019 Model 3. Is it worth doing in 2024?

Also, which third-party brand would you recommend: Hansshow, EVoffer, or Satonic?

Thanks!

Malaromane, thank you so much for making me aware of this thread. I was only reading that other thread that wasn't of any help and has already gone dead. I unplugged that 2-wire connector like you all suggested and I've had no PCS_a022 errors since then (it's been about 24 hours). Also, my car is able to sleep for the first time in 3 months. Totally regret getting that power trunk mod from Tesla. 2019 Tesla Model 3 (firmware 2024.3.25).
