Onstar telematic communication module Defective.
My brand new 2025 Silverado EV has been sitting at the dealership for close to a Month now. I need someone to give me my money back for an 80k truck I can’t use. We definitely need a class action lawsuit for this shenanigans. Obviously R&D seems to sucks at this company.

My 2025 Silverado EV did the same thing. Prior to leaving for a cross country trip. My dealership told me, after multiple conversations that is the reason why I drive a gas truck!! AND he said I don’t know why you people buy these, YOU PEOPLE??!!!!! He said they would give me a loner if it was a safety issue and I said the on star doesn’t work if I get in an accident, HE HAD THE BALLS TO TELL ME TO USE MY CELL PHONE!! When a vehicle relies so much on a part how the hell could it be on national back order??!??!! They would give me a rental nor reimburse me for one after spending 108K on this truck. It’s 3 months old and I wanted to trade it in they had the audacity to offer me 50K !!How do they possibly sell a vehicle they don’t have parts for. They NEVER NEVER should have removed apple car play!!!!! Was so happy with this truck when i bought it but now i wish i never had, this is only the first issue who knows what the future holds with this truck

Mine is not working anymore too and part still on backorder.
Please give us the part number for the module so I can try to source it myself.
I am also looking to find the GM/Onstar defective telemetric module part number. I've just spent an hour looking for it, and although I could find info on many modules, anything with Onstar in the search returned, "We couldn't find anything for "onstar”. I would also like to know the country of origin for the module. Could GM be playing us and delaying the replacement process to avoid paying a tariff of anywhere from 100-250%? If they delay the process until the courts or Congress repeal the tariffs, it could save them millions of dollars.
This may involve two different modules: a Serial Data Gateway Module and a telematic module.
However, GMC has a Customer Satisfaction Program, GM# N242435631. Through this, your dealer should be able to repair it for you free of charge, and your OnStar functionality will be restored after the repair.
We realize how frustrating it can be experience concerns with the OnStar Services in your vehicle. For additional information about the required parts for repairs, please connect with your involved dealership. For any additional questions, you can always feel free to send our team a private message.
UPDATES. GMC customer support enthusiastically called me, and the dealership enthusiastically helped me file a claim with GMC. However, GMC denied my claim to replace telecom module . I recently reviewed numerous Chevrolet and GMC Carfax records and found that most vehicles had their communication modules replaced free of charge through a friend program. This is a clear product defect, yet GMC not only failed to disclose this information, but is charging some owners for it. If GMC charges any owner whose communication module is damaged, I recommend that they obtain a lawyer to represent them and sue GMC for compensation.
I am in the same boat. My 2025 AT4 Yukon has been rotting away on the lot for a month now. I actually stopped by this weekend to grab my registration out of my glove box and it was completely dead. Cobwebs on my tires. They are letting my $86,000 cars battery die and yes, sit there and rot. I am not happy. No ETA. yesterday I was told maybe within the next month. But basically I shouldn’t complain because there are 4 people waiting behind me. Well I’m sorry for an EIGHTYSIX THOUSAND DOLLAR top of the line SUV. Catch me complaining.

With all due respect, this is the same generic response your team is sending to everyone in this community and you all know perfectly well that the dealerships do not have an ETA for the back order. You want to help, tell us when all these dealerships will receive the parts. 26 days now at the dealership, who supposed to pay for this loan? Send me a message that is not a script.
