Infotainment center and On Star not working
my infotainment system on my 2021 GMC Sierra 1500 denali duramax has crashed and now shows a cadillac logo on startup then goes to black screen of death. Onstar is inoperable, usb power plugs are intermittent, no radio, no bluetooth, no wifi and no navigation. on my 3rd day driving my $70 truck like this. been to 2 dealers and they both said i would have to leave it for 2-3 days just for evaluation. Each said they were not aware of this issue. after 2 days online i see this is a know issue and has been at least since 2021. lots of other GM owners have this exact issue! this is my 12th gmc and may be my last. not sure i can trust the brand or the dealer network anymore. When my truck had 50,000 miles the dealer service department told me that GM recommended i replace my front lower control arms as standard maintenance recommendation from GM!! What kind of plastic truck needs this done at 50K?? unbelievable.
I have the similar issue. I leased a brand new 2025 Chevy equinox EV on 2/25/2025 from Harbor Chevrolet. OnStar has not been working from the day 1, salesperson told me that it would be a simple fix and delivered the vehicle home to me. I had to take it back to the dealer as advised from OnStar as they were not able to fix the issue for device functionality testing and for the dealer to work with OnStar TAC. I am being told from the dealer that they were not able to fix the issue and wants to deliver the vehicle back to me. I told them that this affect my safety, use, and value of the vehicle. They do not agree. This is so preposterous. I am so disappointed with Chevrolet.
