I have a 2023 GMC Denali and the Onstar Module stop working over a month now. Took it to the dealership the ordered the part but they have not received or have an ETA on the part since. What is the deal with this part that is is so difficult to order?

I have the same issue. The check engine light came on and was intermittent. I took it straight to the dealership when it went on and it took 4 days to diagnose only to find that the OnStar Module is backordered. Meanwhile I'm paying a monthly subscription. It sounds like this is happening to a large number of people. It seems unclear which safety systems this affects, but with now ETA it's very frustrating.

Just wanted to chime in. Same exact issue. Through check engine light then discovered OnStar was out. Reconnected briefly and then has been out 3 weeks. Chevrolet Suburban Premier 2022. 12,000 miles. I didn’t get told any cost for repair but instead no part ETA. We drive with our kids and the WiFi was a convenient feature along with the connected apps. Shame on GM, Chevrolet and OnStar. There is no doubt this is a recall that needs to happen but they won’t call it because they can’t fix it. Surprise surprise. 86k car time to lawyer up Chevrolet cause a lawsuit is coming your way for damages and loss of safety features and the cost for me to trade this in for another non GM car. This is across all their makes. You guys are losing a lot of customers have fun with the next bailout.

2022 GMC Yukon XL - onstar module died 6 months into owning vehicle...was replaced. Recently had the software update (recall) and now module is dead again. WiFi doesn't work, on star buttons dead, and now many features of my car don't work (speed limit signs, maps, google talk feature, etc). Part is discontinued...therefore never able to be fixed again. Honestly think this is the final straw after being a loyal GM customer for 20+ years.

I have a 2022 GMC Denali Ultimate and the OnStar module has already failed with 10,000 miles on it. Took the dealer 4 days to diagnose. Now the problem is that this OnStar module used in soooo many GMC and Chevy vehicles is not available and no ETA as to eventual availability. And my forced OnStar subscription for a non-functioning unit runs out in 2025.To further add insult, there are over 30 new GMC/Chevy vehicles with the exact same module needed sitting on the dealer's lot. To have a 2022 high$ vehicle with an almost new common part needed unavailable with no idea when the part will be available is ludicrous. Checking online, many folks with my new era vehicles have waited months for their OnStar module to become available.

I have a 2023 GMC Yukon Denali. The Onstar module failed. Dealer said its back ordered also. No time frame. This part controls a lot on the Yukon. No rear TV's, Speed limit, Onstar, maps,clock, ect. Onstar subscription is still going. Its sad to have a vehicle this nice and new and cant get a module. Any help?

Same issue with 2022 GMC Yukon Denali - module stoped working shortly after purchase and it took 6 months for a new one to available, finally replaced in mid-2023. We are back in again with the same issue, module crapped out again. So frustrating.

I am having the exact same issue as all above, 2022 Escalade. I'm late to the game, I guess. I just realized that the module has not been working for 12 MONTHS. And I've been paying the monthly service fee. Dealer is telling me it will cost $850 to replace. I am not willing to pay that, and it seems it's not actually available anyway. Onstar customer service is telling me they don't do refunds beyond the time I notified them. For as much as we pay for the vehicle with these advertised features, this is not acceptable.

I recently purchased CPO 2022 Tahoe LT from the dealership. I went to do the welcome call and button wasn't illuminated. I called onstar and they tried to trouble shoot and then told the sale person a diagnostic test needs to be ran. I went back to the dealership. The dealership said the module needs to be replaced and its on backorder so they arent sure when the problem will be fixed. I agree with many of these comments that GM should issue a recall on this. I have a 2021 HD 2500 Silverado and dont have the issue with that vehicle.

I’ve had my Equinox EV 6 months and I’m pretty sure my OnStar module is failing. Vehicle is showing to be up to 30 minutes away from where it actually is. OnStar button doesn’t work, the app doesn’t communicate with the vehicle now for more than 24 hrs and I wasn’t able to charge at a Tesla station tonight… couldn’t control it from the app or the headunit. Only way I can charge is to plug into my wall outlet at home. Over an hour on the phone with OnStar two nights ago with no improvement with a promise to be contacted by a level 2 rep the next afternoon that never happened. Pissed beyond measure now. Scheduled a dealer visit next week where I bought it because the dealer 10 minutes from my house has refused to do past warranty work on my vehicle because I didn’t buy it there.
