After making its debut with the 2020 Cadillac CT5, the GM Global B electric architecture can now be found in several General Motors products across its brands, allowing for quick and efficient handling of software issues through the use of over-the-air (OTA) updates. Now, GM Authority has exclusively learned that the Detroit-based automaker is revamping the way it goes about OTA software updates.
First, some insight as to why this revision is warranted. Over the course of Summer 2023, roughly 4,000 vehicles across the Global B platform – mainly vehicles like the Chevy Colorado, GMC Canyon and Cadillac Lyriq – were left incapacitated after a few updates. In response to this, The General is currently in the process of revamping how it handles OTA software updates.
Notably, details as to exactly what this entails are scarce at the moment. However, we’ll be sure to provide updates as we learn more.
For background as to exactly what happened, here’s the gist. There were reports that some Colorado and Canyon models had their batteries drained following what was believed to be a failed software update. Interestingly, this issue appeared to be entirely random, and affected a small number of vehicles.
Naturally, GM Authority reached out to General Motors back in July for an explanation, to which the Detroit-based automaker responded that it was working on a solution.
It’s worth noting that one social media user claiming to be a General Motors tech alleged that the issue is related to a radio software update failure that leaves the radio in affected units locked in recovery mode. This individual suggested going into the update preferences menu under system settings, and turning off both the “download updates in the background” and “download updates via Wi-Fi when available” options in order to prevent the radio software update from being performed, which could drain the battery if it fails. GM also instructed dealerships about how to handle failed OTA updates.
