Mazda's $10 subscription for remote start sparks backlash after killing open source workaround via DMCA takedown (www.carscoops.com)

Mazda recently surprised customers by requiring them to sign up for a subscription in order to keep certain services. Now, notable right-to-repair advocate Louis Rossmann is calling out the brand.

It’s important to clarify that there are two very different types of remote start we’re talking about here. The first type is the one many people are familiar with where you use the key fob to start the vehicle. The second method involves using another device like a smartphone to start the car. In the latter, connected services do the heavy lifting.

Transition to paid services

What is wild is that Mazda used to offer the first option on the fob. Now, it only offers the second kind, where one starts the car via phone through its connected services for a $10 monthly subscription, which comes to $120 a year. Rossmann points out that one individual, Brandon Rorthweiler, developed a workaround in 2023 to enable remote start without Mazda’s subscription fees.

However, according to Ars Technica, Mazda filed a DMCA takedown notice to kill that open-source project. The company claimed it contained code that violated “[Mazda’s] copyright ownership” and used “certain Mazda information, including proprietary API information.”

Some models are as easy as removing a fuse or unplugging an optional component from the infotainment system. So a "quick" 1-hour process can remove that noise from the car.

But I really shouldn't have to rip apart my car just to remove spyware and nagware.

I might regret not searching about this before running my mouth here, but I would assume most automotive manufacturers, in 2024, are soldering the wwan modules onto the main board of the infotainment system for cost, and to prevent user removal of their subscription vector.

I would also assume most manufacturers who are converting standard automotive features into paid subscription services that dubiously rely on SaaS backends, are NOT also designing isolated architectures that separate the IoT infotainment system from the car's critical systems like drive control, transmission, brakes, etc. I'm guessing most at least have CAN bus connections linking them together.

But I don't know enough about cars and automotive systems to even pretend being knowledgeable. So, if anyone here is actually well versed on this subject (and not just searching forums before replying to me), please tell me I'm wrong, and how so.

Seriously, I want to be wrong about this.

actually well versed

That's not me, I mostly searched forums and whatnot. My cars are all old enough that they don't have this nonsense, and while I am handy with cars (do all my own maintenance), I'm not a mechanic, so I don't have direct experience.

That said, at recent-ish Chevy cars w/ OnStar seem to have separate power and board for the wwan. I've watched a couple of these videos, and they seem pretty legit.

And with a quick check on Mazda, It seems you have two options:

call customer support to have the TCU disabled - ends data collection and interaction, but the device can still be detected and communicated with
remove the TCU - need to look up where it is, but for the '23 CX5, it's below the center console; removal would turn on warning lights since it can't find the device, but AFAIK it shouldn't prevent vehicle registration or regular car operation

Again, I haven't actually done this for any car, but it's definitely something I'm going to be looking at before deciding on a make and model because I intend to remove whatever tracking BS they put in.

Maybe I'm missing something here, but OnStar is a 3rd party service, so it makes sense they would have a bolt-on device that can be removed without too much concern for the rest of the car's functionality.

Also, isn't a TCU something that controls a car's drivetrain and transmission?

Edit: nevermind, just searched and found telematic control unit. Interesting, thanks for the info, I might look into this more if I have more time later.

TCM is the thing that controls the transmission
