Telematics control module not working
My $100,000 gmc Yukon Denali onstar and WiFi works about 1/4 of the time. This has been happening for 3 months the dealer said it’s a bad telematics control mogul and it will cost over $1,000 to fix, and it’s back ordered Of course my warranty expired. I would like Onstar’s to credit my account the last three months and until the new modular is installed. Also since it is such a frequent problem GM recall and fix the modular at no cost!!!
