NHTSA Complaint #11628473 — 2023 CHEVROLET TAHOE

Onstar Telematics Module failure. Part is on backorder with no ETA. This module failure removes the navigation, Onstar services including safety notifications, clocks can stop working, Android auto/Apple Carplay services are not functional or intermittently working. My vehicle has stalled out at a red light. GM is refusing to cover the replacement saying it is out of the bumper to bumper to warranty but they have so many of these needing replaced they can't say when they will get the parts. Module has been confirmed dead by a mechanic at a private shop and by the dealership. GM states this is under the bumper to bumper to warranty even though it controls parts of the power train and should be covered under powertrain warranty as well.
