I remember yanking out the onstar unit in my 2015 silverado to physically disconnect the cell antenna. This was (is?) the only practical way to disable cellular in that vehicle.

Kudos to Rivian for making this a supported user privacy feature.

Similar I got a new 2025 4runner last summer and...

A: never once installed the app or registered an account, which flummoxxed the salesman so much he argued with me for 10 minutes trying to say that I had to set up the app to even take delivery, even though I paid cash in full. He even cried to mama (the manager) to find out what to do about this impossible situation. In the end, of course you do not actually need to install the app, even temporarily just for a one-time setup, or even register an account. But MAN do they want you to.

B: Within a few weeks found that someone makes a kit that lets you completely disconnect the telemetry & internet functionality module while providing some pass-through connections that normally go through that box.

Apparently in this case all the bad stuff is conveniently in one box you can disconnect, and still have normal bluetooth for android auto, apple car play, or plain bluetooth headset & media. So still have gps & media on the console stcreen. I can only assume that this won't stay so convenient. They could have anything require anything else any time they want.

They do offer an official way to disable all internet features (remote start from your phone from any distance, remote vehicle monitor, tracking/shutdown, etc), but all that does is disable the useful functions for you, while not disabling any of the functions they use for themselves. It's still actively logging and uploading data, and they still have the ability to remotely track and even disable the vehicle.

I've been to the dealer (different from purchase) once for a free oil change and they didn't say anything. So idk if they even tried to do any updates, or they have some other way to do it or what.

As someone who got into a rollover accident which ended with my car upside down on a freeway, hearing only the onstar person talking to me while half conscious, this is sad.

I do distinctely remember strongly disliking the user agreement I signed for the "internet connected" features of the car when I bought it. 100% rubbed me the wrong way and I couldn't' find a way to opt out, and I wasn't so motivated to physically remove it from my new car. Thankfully.

Shouldn't have to trade privacy for safety.

  • There's absolutely no reason an emergency e-call system needs to connect via the car systems such as infotainment. It could be a standalone module that does its own thing regardless of whether the car is permanently disconnected from everywhere. Probably should too, given its nature. And not just could: there are aftermarket e-call systems that do not integrate beyond requiring 12V supply.

    This is how cars used to be made. Features were standalone modules: there could be some bus traffic about optional data (wiper module with rain sensor could broadcast that it's raining and body control module could hear that and could be configured to close windows when raining) but they weren't strictly integrated in any meaningful capacity. You could change the radio unit to whatever you liked: if you were lucky you could get one that can actually understand what the other modules in the car were saying and show some non-enterntainment info on its screen as well. Navigation used to be a standalone system that had GPS receiver but nothing else in the car couldn't necessarily tap into the location data.

    SUre, it meant some more wires and maybe the features had disconnects because they weren't aware of each other that much but all in all that was a good thing. It kept everything simple, isolated and repairable. Now because of more integration the modules need to know who they're talking to which leads to bizarre things like having to code in new headlights and pair them with other modules or they won't be recognized and just stay off.

    My phone does this now. Most phones do it now.

    • Maybe in theory, but I trust Apple to detect a crash correctly about as far as I can throw my iPhone without breaking its glass back or front.

      This is the company whose flagship voice assistant, in 2026, can’t tell the intended recipient in a sentence like “Text Bob Mary signed the deal.” And if my phone happens to be thrown into the back of the car by the crash, I doubt anyone will be able to hear me.

      Not to mention that OnStar has operators who talk to first responders. the cell phone thing will just call 911 and hope for the best.

      I pay for OnStar, and think it’s worth it.

      Only if it hasn't been crushed, damaged, or otherwise flung out of the vehicle that crashed so violently that it's actually upside down, as noted in the original comment.

    Get an iPhone or an apple watch - they offer this same service with a more sane privacy policy.

They've fixed that in later models, disconnecting the module disables the dash now.

But don't worry, the FTC is out to protect you. Their settlement with GM says that can only sell your name attached to zipcode resolution location data and only sell your precise location trace attached to an opaque ID rather than your name.

  • I've reliably disconnected Toyotas and VWs by pulling the cell antenna connections from the telematics modules in the dash. The GPS antenna is separate and still aids in carplay navigation.

    • Makes it less likely to connect presumably, but at least on some cars it will sometimes, rarely manage to get out-- and of course it'll upload its queued data if it can. (In particular I know of someone where a GM car managed to get data onto the Lexis Nexis report with the antenna disconnected-- now with their FTC settlement its harder to tell if its still getting through, unfortunately).

      Or if you take it in for service and they plug the antenna in. Better than nothing, but if your privacy and security depends on not being constantly tracked it's not good enough.

Saying you need to physically take the car into them, unless you're in a country that requires them to provide the option, and disabling other features out of spite isn't what I would call a supported user privacy feature.

Same. This is the first thing that I've ever read that makes me think I might be willing to buy a modern vehicle.
