I have a 2018 Silverado LTZ 1500 and the radio is so glitchy it is unusable. I would think something like this would be covered under a recall since the issue is wide-spread.
Please reply with how to privately DM you with the VIN, we have a made an appt with our dealership. Yes, we’ve paid for all of the updates on the system so that is not the issue.
