The folks at General Motors haven’t master yet the beauty of remote software updates?
Phew? What a bunch?
This may be something for which they intentionally left out over the air updates. Tampering issues come to mind.
Have a 2021 Blazer that was built in Mexico and put wrong refrigerant in and wiped out whole system.Will have to replace the whole system.But saved money on having it done in Mexico!
At what point will people stop buying GM products besides the Corvette and Camaro. The only two revalant vehicles remaining in their entire line. I hate it but GM is over.
My 2021 Chevy 2500 received the update today. Remotely with no issue via the trucks connection to my home internet. No service appt required.
Is there a software update for the 2014 Chevy Malibu? If so, how do I get it? Thank you.
