I drive a Jeep. Jeep owners tend to skew libertarian & DIY. Owners have found you can bypass or cut power to the modules via fuse pulls. I bet you can do this on other makes. If anybody cares, I can post more. I have not done this myself.

  Jeep Wranglers & Gladiators are very similar. This thread has links from how to opt out, where Stellantis is selling data, to potential module pulls, and possibly faraday cloth attempts, attaching resistive dummy loads for antennas, pulling 4g modem.

And then there's VW who decided that the Bluetooth microphone should be on the same fuse/module as the CAR-NET modem, so it's hours of work if you want to be precise about what you disable.

Slightly off topic, but you you mentioned fuse pulls in a Jeep...I'm a glutton for punishment and I've always driven a Jeep (though I do have a 4Runner for my reliable car) - learned to drive on a CJ. Anyway, the head unit in my JK stopped turning off when I took the key out - so that was a fun battery-draining episode. I've been waiting for the weather to get nice to pull the head unit and put something else in there, so in the mean time I just pulled the fuse. Of course the head unit is responsible for publishing outside temperature to the CAN. I don't care that the dashboard says --F instead of a temperature now, but on a cold start, the ECU doesn't know if the oil pressure is high because of a fault of just because the oil is cold. So if I get on the throttle even a little before the engine is warm, I get a CEL now. The joys of Jeep ownership.

  Why in the world does the head unit manage temp readings. Did they just wire the temp sensor all the way to the console?
  - michaelrpeskin 2y ago
    It's the ambient temperature sensor, not the engine temperature sensor. My guess is that the head unit either contains the sensor or is responsible for broadcasting it. The head unit talks to the dashboard to redisplay nav instructions, I'm guessing it's also responsible for sending the temperature info to the dashboard. And since I pulled the fuse, all I get is --F, so the information isn't available on the CAN. Don't know why - I'm not an automotive engineer :)

  I think those electronics are in the head unit mainly to provide interior weather resistance - just a feature other car designers don't generally need to worry about. JK may have more CEL's than a CJ, but a lot more comfortable ;) but probably slower than the CJ

  A family member owns a Jeep (2016). It's been nothing but problems for them. They were brand loyal. But they've really gone off the rails lately. Jeep ranked 34/34 (dead last) in consumer satisfaction in Consumer Reports' 2024 rankings.[1] [1] https://www.consumerreports.org/cars/cars-driving/which-car-brands-make-the-best-vehicles-a6159221985/ https://www.consumerreports.org/cars/cars-driving/which-car-...

    Jeep has never been top o' Consumer Reports. If you want to increase the odds in your favor: - Wrangler or possibly Gladiator only [high volume production] - Lower tier trims to reduce electronic malfunctions - No diesel - No first 2 years of new model - No Covid years I've mainly driven Wranglers my entire driving career and had very few problems
