Joined the forum specifically because of this issue. You are the only person I have found on the internet who is having the exact same issue I am.

2018 Acura TLX V6 SH-AWD Technology Package purchased February of 2018. CarPlay worked fine until March of this year. Mine and my wife's iPhone XS phones get the same error message you posted. Sometimes right when they are plugged in, sometimes CarPlay loads for a few minutes then returns the error. We have used multiple different cords to connect. Both phones work fine with CarPlay in our 2018 Subaru Outback. Our son's iPhone 8 works fine in both cars.

When I had the car in for service at the dealership, I asked them to investigate. Unfortunately, both service guys are very strong anti-Apple guys, so they just blamed it on Apple. They also told me the firmware can not be updated on the 2018 TLX infotainment system.

I have spent multiple hours on the phone with both Acura tech support and Apple. No one can explain this or provide a solution. In fact, the Acura technical person started reading off the disclaimer to me that Acura doesn't guarantee the system will work, etc. Very frustrating.

I have tried rebooting the entire infotainment system. I have turned off Bluetooth and Siri on my phone. I have deleted the phone in the Acura smartphone system and restored the smartphone settings to default. I have forgotten the car on my phone. Nothing fixes the problem.

I have noticed that sometimes my phone is listed as an "unnamed" iPhone in the Acura smartphone system, and then I end up with two phones listed... my named phone and my unnamed phone. Deleting one or both does not resolve the issue.

At this point, my plan is to call my salesperson and ask if there is a 2018 TLX on the lot that I can come in and see if my phone will connect properly. I'm also going to call a different local dealership's service department and see if I can find a serviceperson who is not biased against Apple products to talk to about the problem. Finally, if neither of those things resolves the issue, I might sign up for the iOS 13 beta and see if that fixes things.

Please let me know what your dealer said/did for you and if this has been resolved, and I will report back with the same!

Another vehicle is probably NOT the answer, because as you stated, it worked fine for the 1st month, & then went FUBAR.
I'd venture to guess, it's an Apple issue; although Acura & Apple do NOT have a cohesive relationship; blame game
Maybe the service manager, will swap out your infotainment system; you'll probably need Acura Corporate to get involved
You'll need a lot of patience, & a little luck
I fought with corporate for a year, before they agreed to replace my bogus transmission, on my 2015 TLX
Thankfully, the 2018 version is light year's better
BTW: the tech at my dealer knew very little about Apple syncing; again, they blame Apple
So far, my IPhone SE/128GB, syncs perfectly, with CarPlay; fingers crossed

unlock your iphone before connecting it to the car. Sometimes the iphone locks/cuts access off to the lightning connector to prevent intrusions.

I'm not sure that's true. The think the charging part and the data part are different.
I'm in the industry and work for a certified MFI Apple cable manufacturer. Just so happens one of our engineers is a big time TSX modder so I'm sure he's on the TSX Gen1 forum so I'm asking him now.
But we are having the same issues with both our iphones. I have done the following to insure it is not the cables
1) Tried three (3) known good cables from us
2) Tried a known good Apple OEM cable

As a note - I am thinking it is an apple issue. I travel a lot and rent a lot of cars with car play. Had issues like this with both a lincoln and caddy within the last 3-4 weeks
