I have a 2023 GMC Sierra 1500 Denali that I had to take in for a dealer for them to tell me the OnStar Module needed replaced. My vehicle is over the 36,000 miles so they quoted me close to $750 to fix it. This $80k truck is only a year and a half old! Mileage should have nothing to do with this part. How is this not something that is covered by GM and/or OnStar? Especially after reading about so many other brand new trucks having this issue.

Onstar,Mileage has nothing to do with the forced Onstar contact placed on 2023 models by GMC. The contract stated 3 years of service, there is no provision for a mileage limitation in the Onstar contract. GMC should supply a device that will provide the service for the contracted time frame regardless of mileage. Selling a 3-year non-refundable service implies 3 years of implied warranty of merchantability for the device supplying the service.

This happened to me. 2023 Yukon AT4 with 17.5k miles. Nothing works: no wifi, no maps, no vehicle info, no onstar. Dealer says no eta on replacement onstar module. This is frustrating and ridiculous. I am now paying for onstar and cannot receive service. In addition, there is no timeline to fix this.

I have been trying to figure out how this is any customers responsibility to pay to have a module fixed on a car that is a year old or less. And when I was sent an email by onstar telling me to call their connected assistance team to discuss this problem, well i called they said oh your onstar isn't connected in your 2023 Acadia. I said no kidding the module is out so they basically say it is not their problem and for me to take it up with GM. Then Onstar sends me an email stating that the 2019 buick i had came with 5 years of service and it is now out of date. I dont even have thar car anymore, traded it is on the acadia. They are no help what so ever and even after a call to them they send me back some BS email telling me my buick doesn't qualify for replacement since it is 5 years old. Oh okay but what about my 1 year old GMC? Doesn't that qualify for you to fix something it have to pay for? It really should be a recall at this point. So many dissatisfied customers that had to pay for 3 years of service whether they wanted it or not and it doesn't even work for a year. This is unacceptable and needs to be resolved and GM needs to fix it not the consumer.

has anyone filed a complaint with the NHTSA regarding onstar? https://www.nhtsa.gov/report-a-safety-problem#index. Since OnStar touts their product as a safety feature the fact that it breaks seems to be a safety recall issue.

I just purchased a brand new 2025 Yukon Denali and all the engine light came on 20 minutes after I left the dealership. Onstar has never worked since new. I took it straight to my local dealer to get it diagnosed. After paying $95,000 for a new car everything should work especially on the drive home from the dealership. GM has no ETA on parts and I am not accepting that response. Here we go with the buy back process.

  Call Onstart directly and they can delay the payments for up to 6mo. while you wait for the replacement. We had to do this with our 2018 Silverado because we had all kinds of issues shortly after purchasing it. OnStar was willing to delay the payments once we let them know there was no ETA for the part we needed, leaving us without a vehicle to drive. Therefore they allowed the delay and checked in at the 6mo for a parts update, which by that point we no longer wanted it.

Hi there,

We understand your frustration with needing an OnStar module replacement on your 2023 GMC Sierra 1500 Denali, especially given the vehicle's age and cost. Generally, warranty coverage applies up to 3 years or 36,000 miles, whichever comes first, which is why the replacement may fall outside of standard coverage due to mileage.

We recommend reaching out to your GMC dealer to discuss possible assistance options, including goodwill coverage. Let us know if there’s any other way we can help and feel free to send an email to socialmedia@gm.com, Please include ATTN: OnStar Community/purduecarter in the subject line.
