To be quiet honest, I think it does not matter. ANC is not that is day and night difference, is more of 10% reduction at its best. They never work quiet right.

My question to GM is, why even bother messing with it (ANC).
 
I got a call from the Chevy Service Dept. GM issued a service bulletin, more of a patch to fix the problem. The fix is to disconnect one of the microphones by the roof liner.

Someone at GM is shrooming. The Owners Manual on page 112 and 131 states clearly the deactivation can be done by the dealer.

Meaning, that can be turned off (if the techs know how) or simply disconnect the microphone cables; For that, the techs need to pull the roof liner.

I believe, that will be issued a software patch for the problem.

What I see is the cable snipping by the glove box is looking better each day.
 
Anyone have the bulletin # on this and has anyone actually had their dealer disable the ANC? Did the issue go away?
The dealer disconnect the microphone from the roof of the car. In my book is bullshît, the dealer can "disable" it, it is on the owners manual. However, does not say how is done. I was under the impression they use the scan tool, they do not have that capability.

As posted before, is either go there and unplug the mic, or cut the cable, pick your poison.

I am under the impression GM will issue a bulletin for a software/firmware patch, but they are very slow reacting.

Personally, I rather go with the idea of cutting the Purple/White cable by the glove box, much easier and cleaner approach; or maybe removing the pin connector from the plug and tuck it in.
 
Looks like GM has a fix for the ANC reverb issue
I just got my daughter's car from the dealer and they applied TB-23-NA-194 to reprogram the Stereo System.

I tried to make it go off and was not able to recreate the problem. Drove in highway and city at different speeds and loads. I consider the issue fixed, it is gone for good.(y)
 
i snipped the cable, didn’t want to go through dealer. after cable snip my issue went away.

manual does say they can turn off ANC
Did you notice if you’ve had issues with receiving or making hands free calls once you snipped the ANC wire? I have noticed that my daughter is having an issue now with hers after we snipped that wire about a month ago.

I’m pretty sure we have same issue. I’m taking my car in soon and I hope this works because that bass noise is so annoying. Also. an entire different issue, my 24 Trax has been making a buzzing and rattle noise, it’s coming from inside the cabin on the passenger side. Sounds like it’s coming from above the cabin filter have you experienced this?
 
We starting to have some issues with random reboots and some static coming from the passenger side speaker. The techs are stomped with the issue. However, we ask for a trade and we traded our paid off 24 Trax RS1 with 16,500ish miles for a 25 Trax RS2 with 5 miles for an additional $3,400 so I made the deal, still paid off. Felt like we just rented the car.

Also noticed that my phone is not paired with the system and my daughter uses an iPhone, she seems to have the problem but not me during the few times I drove the car. Could it be the iPhone is crewing things up?

Anyway, on the 25 Trax with the bigger infotainment and digital dashboard, we hace 0 issues, knock on wood, in 2,000ish miles.

Apparently the very firsts 24Traxes might had a screwie batch of infotainments that is causing the issues and corrected with the next batch. Who knows, just speculating on my part.
 
Just in my observations, the majority of users with iPhones are the ones having the most issues with the system. I use an Android phone and have only had one screen lock up due to Android Auto crashing on my phone, and i had one instance where the screen rebooted itself while driving. Other than that it's been absolutely nothing out of the ordinary.

I'm an android user and constant problems with Bluetooth I can call and I hear them but they can't hear me. I don't get it
 
Since June, my radio stops and I get a message saying to use the app to play the station. It stops playing in about 20 seconds. Then I have to push the station 'button' to play. I don't know what has changed since June, but it has to do with my Android phone. When I have it shut off, no problem playing XM. Also, if the car is already on, and my phone off, the phone will NOT connect to anything when turned on inside the car.

I've decided to sell the car. I can't deal with it and the dealership any longer!

There were a couple Android Auto updates since the end of May that were pushed through by Google, it may have screwed itself up and is now interacting with the Infotainment system strangely. I usually run beta versions personally and currently I'm on version 12.5.142944, they just push 12.0 out as a full release this week.

Here's a suggestion, and it works on all Fords who have the same problems. Turn off the VPN on the Android phone and the problem seems to go away. I'm looking at buying a red Trax when they get hold of a LT model. I current drive a '13 Ford C-Max hybrid (yeah we keep a car quite awhile) and experienced connectivity issues until one of the service department guys told me about turning off the VPN. With the exception of a few pop up ads on Google it's worked great for over a decade. When I left the flip phone for the Samsung smart phone I turned off the VPN and it's been flawless. Hope this helps.

I also have Android Auto, and it's only crashed on me once while using Navigation. Otherwise no problems. (y)
 
What I am noticing is the unintended consequences of the technology; specially the integration of technologies compounded by flaws in the micro service architecture.

To put in lame terms, the tech advances so changes are applied like software/hardware updates. These software/hardware depends of micro services, or let us say, other smaller software that manage certain functionalities.

As an example, most phones are setup to listen for certain commands like Siri, or Hey Google, Alexa and such. Since the Mic is open, it might picking background noises and affecting... let us say the noise cancellation.

So who is to blame, GM or the Phone Mfg? What we see a is herd of pissed off costumers and a car company running in circles trying to figure out what went wrong and how to fix it.

I have 2020 Silverado 2500 HD Duramax, my phone is paired but I have no other service beside the usual phone service, and I play MP3s with it, all the Voice Activated Services are turned off or disabled. I have no issues with the phone on that truck. My other cars are old school that use jacks for audio, nothing fancy.
 
Has anyone experienced any speaker reverb?
Speakers will occasionally/randomly just start a deep reverberation that shakes the mirror. I have had it happen on FM, XM, BT.
Bass setting does not make a difference nor does volume level and adjusting volume does not change the loudness of the reverb. It will even continue if you mute the speakers.
Duration is from a few milliseconds to a couple minutes.
yes and its so deafening
has anyone been able to have it fixed
