For many years, GM and other manufacturers have been doing software updates through a computer interface at franchised dealers. I remember bringing my Hyundai in for just that service. I suspect that method has been preferred by them (franchised dealers) instead of over the air (OTA) updates like Tesla does. I would guess that Tesla has chosen OTA updates since they don't have franchised dealers.
GM does do OTA updates on the infotainment system in some of their cars though.
Our point was how is a Tesla voluntary OTA software update done in your garage in 20 minutes labeled a recall, while a mandatory appointment AT a GM dealer to fix a software problem an update? If GM is well versed in OTA updates, why not this one?
Tesla controls all the software in their vehicles by design, legacy automakers do not. Ford CEO Jim Farley admitted last year that they don’t control most of the software in their cars, as many as 150 of their suppliers do. GM and all other legacy automakers have this issue substantially - it’s been the industry model for many decades. It’s one of the key reasons legacy auto is many years behind Tesla in EV technology. Ford, GM, VW, Hyundai, and the others can’t just take parts back in house after farming them out to 150 suppliers for decades. And getting 150 suppliers, many who contract with some/many automakers and other industries, aren’t all going to get on the same (software) page overnight or give up their IP.

“We farmed out all the modules that control the vehicles to our suppliers because we could bid them against each other," said Farley. "So Bosch should do the body control module, someone else to do the seat control module, someone else to do the engine control module. We have about 150 of these modules with semiconductors all through the car. The problem is that the software is all written by 150 different companies and they don't talk to each other," Farley said. "So even though it says Ford on the front, I actually have to go to Bosch to get permission to change their seat control software. Even if I had a high-speed modem in the vehicle and I had the ability to write their software, it's actually their IP.”
What Tesla can update OTA is far more comprehensive than any legacy automaker - there’s no comparison. Legacy automakers OTA updates are mostly infotainment, maps, OnStar and the like. Most legacy auto “OTA updates” are still a several hour process uploading from a computer to a USB, taking it to car and letting it update. I know because I’ve done it on Hondas, Toyotas, Subarus and Hyundais many times - it’s a PITA. Or you pay your dealership to do it there for you for $250. With Tesla you can be asleep as the car is updated via WiFi.
Not only is legacy auto very limited in what they could do OTA, they (dealers) want you to go the dealership for recalls, so they can sell you on other paid services you may or may not need. Another tradition that legacy dealers are going to fight tooth and nail to preserve.
I applaud moves to true hands off OTA updates like Tesla does been doing routinely for years. It’s a painless as updating your iPhone, iPad, etc. Here’s a recent example of a GM OTA update, a problem identified in July and not fixed in October?

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. 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.
