Update from my situation.
Scheduled a service appointment for 8am this morning. Pulled up at 7:55 and the service managers first question was about remote start.
She said there is an issue with remote start and not to use the app or the fob to remote start.
I checked the truck in, tossed my stuff into the 2019 Silverado Custom they set me up with as a loaner and headed home.
About an hour later I received text alerts about the need to service the engine and transmission systems. Apparently the tech set off all sorts of shit while clearing codes and testing.
They found a brake system sensor that "had gnawed wiring as if a rodent has gotten to it". Sensor won't be available for 5-7 days.
So my brand new truck, with 230 miles on it will spend the next week at the shop while I drive their loaner for work.
Not happy, but not quite pissed yet. At least they didn't put me in a Smurf Blue PT Cruiser like the Dodge dealership did years back. Drop off a 1 ton and leave in a go cart.
Will update after I pick the truck up and speak with the manager and tech.
