is it when the car is running?

i recently added a subwoofer to mines and when engine ran it made a loud reverb (2024 model as well)

ended up being the active noise cancellation interfering, i ended up cutting the wire and disabled it. problem gone.

can’t say it’s 100% what you are going through, just sharing.

If your setup is all stock may be worth asking dealer about it.

 

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.

Yeah at 1800 rpm’s … it’s really annoying

 

Yes. And seems to be random. At least, I can’t figure out what condition causes it.

 

It seems to be more than just at 1800 RPMs. I can’t determine whats causing or how to fix it. Sometimes it’s short duration, sometimes long. Sometimes 2-3 times in a 1-2 minute period… sometimes it’s once in 10-15 minute period or never in 30-45 minute trip.

 

Car is going to dealership today, will let you know what they find.

Update: Dealership didn't find any smoking gun but says there is a GM Bulletin about it, listing no cause determined or solution available.

 

Was told the same by the dealer also :/

Could this fall under Lemon Law?

Where is the anc wire?

 

I am also having the same problem, seems to happen more often when I have more people in the vehicle. Typically when I drive alone it happens much less frequently and doesn’t vibrate as loud. I would be curious to see what disabling the active noise cancelling does. Did anyone determine where we can disable that?

Same issue here! After taking car to dealership with no resolution , I Called GM corporate and now have an escalated ticket with them for a resolution . I bought this car for my son and after a 5 minute ride with him I was ready to jump out of my skin! I will push this issue with them to fix ASAP they had no issue taking my 27k they fix or LEMON will be enforced

 

Please keep us posted, I have my vehicle scheduled to be looked at next Monday at my dealership and from what I have read so far on other forums, will probably be told the same thing as you. Did they charge you for looking at the vehicle at all? In the bumper to bumper warranty policy I see that it has an exception for “slight noise and vibration” even though this sound is definitely out of the normal and can be very loud. Hopefully GM will figure it out and fix the issue, seems that quite a few people are having the same problem. I had 3 people in my vehicle this past weekend and whenever I hit 54-55 mph I would get the vibration and it wouldn’t stop till I got to 56 or dropped to 53, seems like a very legitimate safety concern from that aspect.

 

Thanks, very spot on. I tested it and it is true. It does happens at around 1800 RPMs at a light load. The point when a car exhaust drones.

There is a good news that requires no wire cutting. On page 116 of the Owners Manual clear states that the dealer can turn the ANC OFF if aftermarket equipment is installed. Apparently you need the Tech 2 tool to do the job. Free unnder warranty, it is like a 15 min job, plug, look at the menu, turn off the ANC.

So I am going to the dealer to tell them to turn off the ANC as an interim solution.

 

This is very helpful! Went to the dealership today and they said that GM is aware of the issue but has no solution yet. They asked that I call in and let them know if re programming my radio fixed the issue (it didn’t) but when I call back in tomorrow I’ll mention the ANC thing and see if I can have them disable it as well. I’ll keep you all posted.

 

The solution reside on harmonics. There is a frequency the system picks up and instead of sending through the stereo at 180 out of phase to cancel the noise, it sends it back as full sync wave. Perhaps is a feedback loop.

I was able to play with the reverb with the throttle. You can make it louder or not by slightly revving the engine as I said, light load, almost coasting at around 1800 RPMs.

It does happens when you play with frequencies, sometimes there is one note, one freq that reaonates. A fix might be a cut off on that specific range, some that a nit-picky individual will notice.

I know, it is a nuance but it is not the end of the world. At least I know where the belly ache is at; and understanding the problem is the 1st step of a solution.

 

I noticed this today on my 2024 Trax. I muted the radio and a very loud, deep hum occurs when barely accelerating to keep it at 28mph and also at 40mph. I was going home from work so didn’t go any faster to know if it does it at higher speeds. Hoping GM releases a recall and fix at some point. It is very annoying.

 

There is no recall as of today.

The dealer contacted me telling me that my solution is reported. Awaiting on how to turn the ANC off. Look in the Owners Manual page 116; the dealer can turn off the ANC.

It does not hurt the vehicle nor is a safety concern. The speed is not what causes the problem, it is about RPMs. 1,800ish RPMs under a light load, it can happen at any speed. As long you drive out of that range you will not hear it.

 

i ended up cutting the anc wire off the harness, if anyone is interested i posted pictures here:

2024 Trax 2RS

Hello folks, Newbie here, purchased a new Trax (2RS) few months ago and really enjoying it. I’ve started out replacing the door speakers (6.5”) and tweeters. Crutchfield didn’t have any info so took the gamble and paid off!

under the hood, i ended up putting sound dampening butyl and foam to quiet down the cabin.

Thanks for the idea, but it is just me, I will like to go the software route and turn it off.

Anyway, how much different was with the ANC out? In my opinion, I think that is not going to be too much of a difference.

 

i couldn’t tell the difference honestly, i play loud music so don’t even hear the road noise

 

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?

 

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

 

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.

 

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

 

Well, I hate to say it but I know I will catch flak with the fanboys, but honestly, Apple sucks

 

Agree

 

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.

 

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.

 

yes and its so deafening
has anyone been able to have it fixed

 

As mentioned above, Technical Bulletin TB-23-NA-194 will fix it or snip the wire. Take it to the dealer for the TB and any other updates you haven't gotten.

 

It's definitely the microphones in the car. The place where I got my sub installed told me the mics were the issue as soon as I unplugged the mics it started working
