Onstar Module Needs Replaced

[purduecarter]

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.

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.

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.

Yep, still having to pay out of pocket ($750), waiting on the part with no eta, and losing out on the onstar services that have been paid for... Doesn't seem like Onstar really cares since they're owned by GM. Onstar emailed me but it basically stated, sorry you're upset and out of warranty on your 1.5 year old truck, good luck working with the dealer. Then mentioned calling them if I wanted to discuss it more.

I would call if I knew I wouldn't be wasting my time. Last two times I've called Onstar I was put on hold for almost 2 hours, and hung up on one of those times (and not called back). 

Thanks OnStar, for the great customer service.

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.

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.

I am in the same boat, my 2023 Acadia's telematic (onstar) module is out and the dealer is got it from is saying i am SOL and have to pay for it out of pocket for a service that was supposed to be on my vehicle for 3 years not 36000 miles or less. And yet here we are after paying all that money for a vehicle and being told it has something it doesn't is ridiculous. Onstar or GMC should be fixing this not the consumer
