I have the same car and want to do this, but not for the reasons the author noted but because the GPS unit in the car is broken when paired with Carplay and has the wrong compass heading causing navigation to be completely useless. I have reported this to Toyota multiple times with videos detailing the problem and they have denied the problem and ultimately when faced with the evidence simply refused to fix it. I've…

I don't work for Toyota, but I do wonder, who exactly within Toyota have you contacted? Maybe you're reaching people who have no idea how to reach out to a real engineer within Toyota?

Earlier quoted context omitted.

In case of Subaru turning off 2G made their modems keep trying to reconnect 24/7 draining and killing battery. Subaru refused replacing batteries killed by defective car.

On my classic cars I fitted a battery quick disconnect in the boot. Might need to start doing that with modern cars too.

Modern cars sometimes have telematic units running off dedicated lithium ion batteries, so killing main battery might not do anything

Modern cars are horrible. I recently discovered that all new cars sold in the EU constantly beep at you for supposedly speeding, even though the system doesn’t work well, and it has to be turned off every time you start the car.

It’s horrible since it gets the speed wrong 25% of the time and 25% of the time it beeps because you are doing 33 in a 30kmh zone because you are just going along with traffic. When you get in a car, you have to spend 20 seconds disabling all those systems. Lane keep assist is downright dangerous as it keeps you in your lane if you do an emergency avoidance manoeuvre. I don’t hate safety system like emergency brake a…

My Honda Civic gets the speed wrong almost 100% of the time in Slovenia where intersections automatically cancel out non-zoned speed limit signs (so no crossed out signs that the car could read). Luckily it doesn’t beep or nag about it.

(Which makes me wonder, is there a flag set to make it not beep on cars sold here? Cuz otherwise people would be returning them en masse)

We need more posts like this. I'd love a follow-up where instead of removing it injects fake data to the system. I am tired of passively being digitally assaulted. If they are going to do this to me without my knowing consent I want to fight back.

I'm always surprised there aren't more projects that just pump random data back into all of these system. I think awhile back there was a plugin that would click on every advertisement it saw over and over, but got shutdown for some reason. But how hard is it to just have everyone inject nonstop data to all of these tracking systems? if nothing else a drive somewhere is going to eventually fill up.

There have been plenty of projects that do send junk data to these endpoints. The problem is the junk data gets users noticed because some manager looking at dashboards gets an alert about some supersonic Corolla driving down the Pacific. And they go yell at the team responsible.

As a result, analytics endpoints generally have some authentication and verification built into them. Obviously, with enough time it's possible to reverse engineer these components. But that's a lot of time and effort vs just blocking the request.

The 2024 Ford Maverick has a single fuse for the telematics unit that you can remove without throwing a code or an error. No idea if this remained true after the 2025-2026 refresh, but worth knowing. https://www.mavericktruckclub.com/forum/threads/telematics-f...

Kias have a “Massachusetts mode” flag hidden behind a service menu (that needs a dealer code) that disables telematics at the owner’s request. However, the service menu pin also has timeout protection that will inject a waiting period between retries so there is no guessing. I don’t think there’s convincing my dealer to get into the service menu and disabling it. I would presume that other manufacturers might have th…

I'm more afraid of the likelihood of someone smashing the window on a modern Kia thinking they can start it up with an iPhone lightning cable (just look up "Kia Boys" if you're confused by any of this) and drive off with it, when in fact, they cannot anymore. Unfortunately, until people stop breaking into Kias I'll avoid the brand in perpetuity.

Just a note about Toyota specifically - There are many blog posts and articles out there alleging that Toyota shares your data with insurance companies. As I own two Toyota's I have read through these carefully and consistently the theme is that the owner was opted into this program without knowing it (likely by the sales person clicking through setup steps to enable every feature). If you are not opted in, I have se…

There was a recent class action suit against GM for this.

You shouldn’t. Apple preserves backdoors in iCloud encryption to enable warrantless government surveillance. They have no other option.

Some brands take software very seriously. This isn't an "entire industry" problem. My experience is pretty small; I've owned the same Tesla Model 3 LR for the last 6.5 years, and the software has been pretty much solid the entire time. There was briefly a problem with echos when I called land lines using the bluetooth and my iPhone, but that problem eventually went away - not clear if it was because the iPhone change…

This does not change the fact that Tesla is shamelessly spying on you. In fact, Tesla takes the software so seriously that it can probably fully remotely control your car. This is not something that I would want, and, if I were to be gifted a Tesla, the first thing that I would do is unplugging the cellular modem. If the car becomes unusable because of this, I would get rid of it.
