No it won’t. Why do people keep parroting this bullshit?
Car modifications only void a warranty if the shop can make a reasonable case that your modification caused the malfunction you’re wanting work done on. If you tune your engine to make more power and then your transmission blows up because it can’t handle the extra power, then yes – you probably voided your drivetrain warranty. But if you tune your engine to make more power and then bring the car in because the power windows stopped working, they can’t deny your warranty claim for that, because there’s no reasonable way your modification could have caused the problem.
The computer network in your car touches everything, engine control, powertrain, body control, SRS, emtertainment system, stc. If the dealer thinks they can get away with denying a claim because you “damaged” the vehicle by removing the cellular antenna you know they will. And it’s not like you can just pop it back on before you bring it in, new cars are streaming data 24/7 into the manufacture’s network, and is visible to the dealer, whether you pay for car control the app or not.

That’s when it’s lawsuit time.
Honestly, they’ll probably change their tune pretty quick the moment they get a demand letter with a lawyer’s name at the top. They do warranty work all the time – and the dealer shop is paid by corporate to do that work – they’re not that motivated to get out of doing warranty work.
It will also void any warantee or service agreement you have with the dealer.

First example I could find.

That is different than "voids your warranty "
That’s just normal dealer shenanigans.
Manually update then?
