Got mine back, it was repaired, not replaced.
Anybody else got the Mac Book pro 15 repaired, instead of getting replaced?
I have a 2018 MBP 2.2 512Go 555X.
I took him to the apple store, they change the battery and the Keyboard.

The latest supplementary update has made my computer feel brand new. (technically it is brand new being a 2019 model but you get the idea). Hopefully, this isn't just placebo.
This is more than ridiculous tbh! How come they are having so much trouble fixing this issue? It's been over a year now :/I just pulled a brand new 2019 MBP 15" out of the box. And guess what?
Installed all updates then installed chrome, ran hangouts and the laptop kernel panic'd within a minute or two.
APPLE PLEASE FIX WTF.
Called Mac store their option is to replace the logic board (HAHA)
MBP 15" 2018 with j680ap T2 chip. Tried a LOT to stop it from:
1. Freezes (10-40 s) in Chrome.
2. Reboots after 10-15 min of sleep.
3. External USB-C monitor (LG Ultrafine 21.5) not going to sleep.
Updated the laptop from 10.14.6 to 10.15 Beta 5. It was my huge mistake.
Update triggered the iBridge update to version 4.0 Beta (17P50521d).
Cannot recommend this to anyone:
+ no more freezes!
+ external monitor working good.
- it is not charging. Even showing that charger is connected.
- !!! Laptop not powering up from sleep mode !!! (5-10 lid open-close cycles and many power button pushes returned it to life)
- Final one = not powering up at all -> I started it in DFU mode. And it's the start of an interesting part:
Apple Configurator Beta is stupid. It tried to downgrade 4.0 Beta iBridge Firmware to 3.6 Release. But it is not allowed! So it bricked the T2 to Recovery mode. Every other attempt the Configurator tried to install 3.6:
US Desc: backwards update not allowed: 17P50521d -> 16PXXX
Domain : AMRestoreErrorDomain
Code : 0x4F (79)
It was a complete disaster.
MB and TouchBar boards were replaced in 3 days. And the new board having the same j680ap T2 chip! Bad luck for me.
A friend of mine got his 2018 15" MBP recently with upgraded j780ap T2 chip and having no problems so far.
Most recent (August, 22) build of T2 version 3.6 (16P6571) version's release noticing fixes to sleep mode issues.
No luck for me. All 3 initial problems are still here.
I could confirm the 2 versions of MBP 15" 2018:
| Processor code | iBridge model ID | Installed machine model ID |
|-------------------|-------------------|-------------------------------|
| J137AP | iBridge2,1 | iMacPro1,1 |
| J680AP | iBridge2,3 | MacBookPro15,1 |
| J132AP | iBridge2,4 | MacBookPro15,2 |
| J174AP | iBridge2,5 | MacMini8,1 |
| J780AP | iBridge2,7 | MacBookPro15,1
| J140KP | iBridge2,8 | MacBookAir8,1 |
It seems that Apple has manufactured two kinds of _MacBookPro15,1_. One of them has J680AP T2 processor, which is distributed to the market at least before April 2019.
The other one has J780AP T2 processor, which should be distributed after that.
It's not hard to find your T2 model:
Open file
/private/var/log/install.log
with Console App and search for
project = BridgeOSInstall
bridgeOS prepare summary: 16P6568 -> 16P6571, update = 16.16.6571.0.0, brain = 16.16.6571.0.0, variant = com.apple.bridgeOSCustomer, macOS = 18G87 (customer), project = BridgeOSInstall-56.4, userAuth = 0, prod fused = 1, model = j680ap, client = SoftwareUpdate, retries = 0
I tried this on my 2019 13" MBP (i5 2.4 GHz model 15.2) without finding this information. I only found some entries that my minimum BridgeOS version is satisfied and no update was necessary. I'm still on Mojave because I wait for 2 apps to be updated to 64 bitIt's not hard to find your T2 model:

My mini has the same T2 model. It never crashed since I own it (April). The only restarts were due to software updates. It works as the family server with a 16TB LaCIE raid drive connected. I also use the mini to do weeklong multi thread Matlab model calculations where daily crashed would be fatal.Just in case anyone came down here looking for a Mac mini Bridge OS crash, the controller model in mine is j174ap. Frequent crashes (at least once everyday)

Last week I upgraded from my 2015 MBP 15" to a 4TB3 MBP 13. It has the J132AP T2 model. No issues so far. I have a Windows 10 bootcamp partition installed that I use through a Parallels virtual machine. At work I connect to an old monitor through HDMI, at home I use an eGPU with a 4k 27" monitor.

J680AP T2 chip here....crashes within 20 min. whenever I use apps using the webcam.
It was good for almost two weeks, had the first internal webcam related crash again just today. Called up Apple and told them it looked like it was working at first but now it crashes just like before, they told me they are still working on fixing this particular problem.Apple just now released a supplemental update for 10.14.6 which is supposed to fix sleeping Mac's that crash and other things. Installing it right now.
EDIT: macOS 10.14.6 18G95, T2 firmware was updated to 16P6571, Boot ROM stayed at 220.270.99.0.0.
Interestingly enough macOS does not show a window telling you a kernel panic happened when this happens, it used to do that before.
