2019 Sierra Denali Bricked Head Unit After Update

Lateral G · February 6, 2019

Has anyone heard of this? My dad's brand new 2019 Denali said it needed to update the infotainment unit, so he hit the "Accept" button and then turned off the truck. After returning a couple hours later, he started up the truck and the main screen was black. Nothing could get it to come back on. So he brought it to the dealer and they couldn't fix it either. They tried to place an order for an entire new head unit but apparently GM doesn't have them available for purchase yet since they're all being used for new trucks. So he's more than two weeks without his brand new truck waiting on a part that has no ETA.

Anyone have a similar situation or have any thoughts?

Unfortunately yes have seen the OTA brick more than once.

The "new" radios are insanely buggy and have a metric ton of updates since they came out in select 2017 cadillacs

Rule number one with updates The vehicle must remain running.

I just did the update a while ago myself. Pushed "accept", shut the truck off and went inside. Checked later and everything was fine. I was hesitant at first but it turned out fine.

Mine said shut the truck off as well, when I came back a few hours later it told me the update was complete.

Same here. Shut truck off. Update was complete on reentry. No apparent problems .

Call Chevrolet Customer Care and tell them about your problem. Also talk to the dealership, ask them to pull the same unit out of another truck and install in yours. Also ask if the GM Regional Rep

will visit the dealership at any time so you can talk to him. Send an email to the CEO of GM Mary Barra if all else fails explaining your dissatisfaction with the repair process.

Per Amprg, I have to add "You forgot to mention court lawsuit and jump off of the cliff with the car after, lol"

Added per your suggestion. Thanks!

Thanks for everyone's replies. The dealer finally got the head unit put in the truck after almost three weeks. Hopefully nobody else has the same issue after the update!
