Onstar telematic communication module Defective.
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.

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.
