After going to 3 button, you go to self diagnostics, then go to errors. Then they have hardware errors and software errors. I used to have a hardware error when problem happened on 12/29, but it looks like it error log got overrun with some other crazy errors. I guess this thing constantly logs errors.
I only got it documented now in software section, but after it happened it was also logged in hardware error, if I remember correctly it was 57D something error. Need to go this section before shutting down the car after this error, other wise it will clear.
The funny part, you can't go with this stuff to dealer, they would not like you poking around in diagnostics. you might even get blamed for breaking it.
Having the same issue with my 2020 A-Spec. Have 8800 miles and purchased in May 2020.
I’ve had multiple occurrences of the failed network comms issue. Only was able to get a photo of the second error (before the fix) and the third (20 mins after leaving the dealership with the “fix” in place). Hunted through the logs to find the same error code aligned with my time stamps from my photos. Three instances below plus photos of the issue.
After replacing some wires and then having the issue happen almost immediately after leaving the dealership they tried to give me the run around about it being a software issue tied to using Apple CarPlay and a future fix was coming. Until then they suggested I not use CarPlay.
I politely let the service rep know that I work in the software space as a federal contractor and as such, have a bit of experience with software and application development. I explained that it was deeply concerning that by simply plugging in an iPhone, my vehicle could randomly lose critical vehicle functionality some of which is federally mandated (back up camera). I suggested they take more time to look through the logs as Acura’s engineers surely would want to be aware of such an issue.
After looking at the logs the technician wasn’t able to determine any new information about the issue so the dealer had me come pick up the car.
They’ve let me know the next step is for the technician to speak with several Acura Engineers/Technicians tomorrow on a call and get back to me as to potential next steps.
Im doing my best to be patient but after reading about other’s experience with this issue, I’m concerned about Acura’s ability to fix and the long term impact this may have on the value of my vehicle. This was my first “big purchase” I made for myself having hit some important career milestones at 29 and aside from this and a few other infotainment bugs (resolved with Apple shortcuts and posted on here previously) I deeply love this car.
I am hoping they’ll have a path forward after tomorrow’s call. Otherwise I’m worried I may need to explore Oregon’s Lemon Laws to see what my options may be if a clear path forward and timeline is not presented.
I had the same issue 6 month ago, would happen 1-2 times per week. After TSB it did not happen for 6 month except one time, so I am not sure if it’s fixed, but I’d did close to being fixed.
I have a feeling it’s related to poor connectors or them getting louse, maybe also technicians not performing TSB correctly.

My main concern here is that there is not a single scenario in which any driver should be able to cause a cascade hardware failure via software (in this case My dealership is firmly blaming the use of Apple CarPlay - a “supported” feature at the time of purchase).
Cars are designed to have extremely reliable and predictable behavior. A bug in the system is inherently an unpredictable element. Our comfort with a bugs known impact shouldn’t distract us from the very real danger of any bug which results the failure of core (and federally mandated) system functionality.

its not a software problem and has nothing to do with car play. Its a hardware issue. The fault causes hardware error, which gets stored but then cleared

I should have you talk to Acura for me then seeing as you know much more than they do.

If I recall, some posters on here have been able to get their dealer to replace the entire infotainment system. However, I very much doubt Acura corporate would approve that, especially since there's a TSB out now, so it's very much based on how far your dealer is willing to go to keep you happy. If the TSB doesn't work, my bet is that Acura will just instruct them to keep doing it over and over and over and over again. Unfortunately, it would appear that Acura figures replacing the system costs more than your lifetime customer value (which in their defense is probably true on average of Acura owners). All that is to say, if your dealership has kicked the can over to Acura, I doubt you'll get this fixed for good.

I was able to see error in hardware error logs, it was something with 57D, After I restarted car, it got cleared. I will definitely take picture.
here is how I know its hardware. Not everyone has this problem, and TSB that replaces connectors does make it a lot better (at least for some people).
Well sorry to report the most recent software update doesn’t solve infotainment issues. I updated on Monday, drove very briefly Tuesday, not at all yesterday, but today the infotainment system reminded me that my 2019 RDX Advanced is the worst vehicle I have ever owned!! Speaker crackle, sound in and out, “ No audio connection”, “Network Communication Lost”, and then finally complete black screen. It only came back up when I pulled over, turned off the ignition and restated the truck. However even then, my phone was not operable. I had to forget device and then connect new device for it to work. Good times!!!!!
Oh, yeah, just kidding!
Have you been to the dealer, it just might be something else causing your issues There have been others who needed the head unit replaced.. Have you done the three finger reboot?

Based on the background that’s all the same instance of the issue - yes? Did you try restoring the infotainment to factory default and repairing your phone after? Since the update mine has been working perfectly so if you haven’t tried those steps it may be worth a shot.

Was TSB applied to your car to replace connectors?

the blue screen you got could be hardware related (TSB), and under some conditions software which 1.5.1 supposed to fix. Its best to have both done.
Well, I did the Factory Reset on the infotainment system, reset all my settings and channels, repaired my phone, and went into the house to continue with my day. When I went to use the RDX a few hours later, once the system booted-up, the sound that came through the speakers reminded me of sitting in front of a fireplace and hearing the crackling of the firewood! Who knew that there was such a nice option with this vehicle!!!
Looks like next step is going to the dealership to to see if they will hopefully do the TBS and see if that helps at all.
I was wondering if anyone here, that has had this issue, has taken their vehicle to Island Acura on Long Island for resolution?
Good to see Acura extends warranty on the MOST bus connector. That basically translate to Acura thinking the part has a high chance of failure within the given years. I would definitely try getting these replaced before warranty runs out!

does anyone know how they plan to contact affected people? I had TSB done, I wonder if there is anything new in this?
Does not look like there is anything new for the hardware parts. They only added a note about routing wires properly to prevent putting pressure on the connectors that go into the infotainment unit.

I actually have an appointment at Island Acura next Tuesday for them to look at it. The person I spoke to said they “need to diagnose the problem. Not sure if it will need the TBS”. I think it needs a sledgehammer!!! Can’t wait for next week!!!!!
Yes, 2019 Advanced. Had the blue no comms screen one or twice whilst driving. Also had the screen not turn off 2 times after I turned the car off which one time drained the battery and another time, I pulled the fuse in order to get the screen to turn off. I don't drive often, only have 6600 miles in 22 months. Was in for oil change today and they did the TSB when I mentioned the issues. Will see how it goes. Have also had tons of the CarPlay disconnects, usually when I'm in a spot where I don't know where I'm going and really need the nav. For a while, I was putting the address in both the car nav and in the CarPlay (I prefer Waze), so that when CarPlay disconnected, I'd have the car nav as a backup. Crazy. Really wanted to love this car.

So it been two weeks since I brought the car into Acura. Upon arrival the 2 service reps I spoke to did not seem to be surprised at all about the issue. The one that I dealt with was aware of the TSB. The job was done in just over an hour. They replaced “the connectors” as described by the service rep. He said the RDX’s come in “all the time” with this issue and “once we replace the connectors, the issue never returns.”
Well, two weeks later and I have not yet had a single issue at all!! (I’m sure I just jinxed myself) I’m very happy that this seems to have cured my problem. I’m hoping that the rep was right!!

Well, of course I spoke too soon!!!! This was this afternoon!!!!!!!!!!!
I don't use SiriusXM, but could it be due to the clouds blocking the satellite signal?
Unfortunately no. It crackled as before, audio cut out on every available platform form. Turning radio on and off did not help. I had to resort to the old three finger reboot for the audio to finally return. Bye bye Acura.
Bringing it back to the dealership this week for the second time to try the fix again!
Well it’s been with the dealership for a week. Had to wait for the Acura field rep to review and his decision was to replace the infotainment control harness. They had to order the part. Hope to have the car back by week’s end!!
