On Star module broken

Same thing happened to me last week....  2023 Tahoe LT... 36.4k miles.  Dealer telling me its out of my warranty and $850 to fix.  Pathetic..  I am also paying for a plan.  This is outrageous that I would have to pay for this considering it has NOTHING to do with the miles on my engine.  My clocks are off, my compass is not working.  How on earth is that something that fails on a 2023 vehicle.  The dealer also said its been happening more and more.    I am waiting to hear back from GM to see if they can pay for the repair.      I own 3 GM vehicles and honestly if they don't make this right I am going to get rid of all 3 and move on to a different company

Just found out today I have the same problem on a 2023 suburban. Had noticed the wifi wasn't working, the light by the OnStar button wasn't on, and also how the clocks were off time. Took it to the dealership and they say not only is it a repair I'll have to pay for, but they don't know when they'll get the module to correct it. Very frustrating! 

Same issue here. 2023 sierra denali, over the 36000 mile warranty, but only a year and a half old. An $80k truck that now doesn't have GPS or any of the fancy technology working that it's suppose to have. Oh, and I'm suppose to fork out $750 to fix/replace a module that many are having issues with. How is this not a recall or free replacement part. What's the point in buying a brand new truck if it breaks next year. There's no reliability on new vehicles anymore. And so much for safety - if there's an emergency, Onstar and/or the SOS button won't do anything... 

Same thing here - 2023 Tahoe, GPS connection has been on and off with my phone, now it is completely severed, WiFi does not work, OnStar does not work. Called OnStart only to find out that it’s not covered by warranty and, after speaking to the dealership, I would be out $700+ to replace the module which is on a back order and no one knows when it will ship. OH, here is a kicker - I have to prepay for that part/labor ahead of time so they can order it. Seriously, GM??? I got the car new, I pay for OnStar preferred plus WiFi and I can’t even use it. This is a disappointment. This needs to be escalated into a recall, plain and simple. 

2023 Bolt EUV...47,200 miles and change.  The WiFi, OnStar, Super Cruise and all forms of regular Cruise Control (Adaptive and Regular) have failed.  Since the microphones for the Infotainment system are wired through OnStar, those have also failed.  THANKFULLY, all of the safety features of the car are still working.  But...the Telematics Module (which I am sure is the same for all the GM vehicles in this thread) has failed--at least that is what the dealership told me.  AND, the part is on backorder. Looks like GM got a bad batch of these modules and they have made their way into many of their models. Tahoe, Sierra Denali, Suburban, Bolt EUV.  I do wonder if there is going to be a recall on this part.  If there are this many people complaining in an open forum, you can count on the fact that there is a 1 in 50 chance that everyone is reporting it here.  That means there have been at LEAST 200 failures of this unit.  The fact that it is on backorder should be very telling...in the world of CMS (Component Manufacturing Services) and the need to do a PPAP (Production Part Approval Process), this means it will be at LEAST 90 days before they get them back on the shelves.  My dealership told me they have had similar parts that took 9 months to resupply.  Come on GM...you can do better than this!  

I have the exact same problem on my 2023 Tahoe. OnStar, wifi, clock, etc. stopped working. Conveinently, we are now out of the bumper-to-bumper warranty. Sounds like this is a bigger problem OnStar and Chevy. What is being done to rectify this? 

I have learned that many other owners of the same model 2023 Chevy Tahoe are experiencing similar issues, which raises concerns about a potential widespread problem.

I attempted to resolve these issues with OnStar, but despite their troubleshooting efforts, they were unable to restore functionality. I was advised to visit my local Chevy dealership for further assistance. However, when I did so, I was informed that I would be responsible for all related costs since my vehicle had exceeded the 40,000-mile mark and was therefore out of warranty.

This is particularly disheartening, as I believe that the issues I am facing with the OnStar system and other components should not be contingent solely on mileage. The functionality of safety and connectivity features like OnStar is crucial, and I feel it should be addressed without being tied to the vehicle’s mileage, especially given that these problems arose well before reaching the mileage threshold.

I am extremely disappointed with the response from the dealership and the lack of support regarding this matter. I urge GM to consider a broader resolution for customers experiencing similar issues with their vehicles. I hope that you take this feedback seriously and look into potential solutions for customers affected by this ongoing problem.

Well I might as well chime in too.... I have a 2022 Sierra Denali, and its been out for a month. Originally took it in for a software update/recall and they thought that would fix it. Of course it did NOT, to had to make a new appointing just to find out the On Star module was bad. I see several other owners having the same problem, not sure why my dealership didn't know about this, but does anyone know what the problem is with getting the new module?

our 2022 suburban premier did the same thing. Intermittent connectivity and check engine light then finally completed died. Part backordered at dealership no ETA. I do think this warrants a recall and likely class action law suit. OnStar gave us a code 1-2-3 and the dealership wasted 2 hours running a diagnosis to come back and say you were right. Clearly GM is not sharing this with dealerships as then a paper trail starts and they are forced to put out a recall that has no solution. I think all of us need to start working together with someone taking the lead. I am sure there is an attorney willing to take this on given the safety implications and cost people are putting out when they aren’t aware of this. 

I have a 2023 Yukon 47,000, 2 years old. First I was told the Telecommunications module was defective costing $1500. Now I'm told that the OnStar module is also bad another $400. GMC unilaterally and arbitrarily added the charge of $1500 for 3 years of OnStar service onto my custom-ordered car (as they did with all 2023 models), they should provide 3 years of protection to the parts that provide the service or offer a refund of the unusable service due to equipment failure. GMC sold 2.6 million cars in 2023, which is close to 4 billion dollars in profit from these forced 3-year contracts, GMC can afford to warranty for the forced contract period
