My 2017 Mazda cx5 refuses to not play the radio. There is no "off" for the audio, you have to choose a source. I use my phone, via bluetooth. But sometimes, for unknown reasons, the car does not connect with the phone. It then falls back to the last source chosen before BT, which is radio. Okay, so I created a flash drive with an mp3 of 30 seconds of silence, played that, then went back to bluetooth. This failback strategy worked one time, then it also failed to recognize the flash drive, and failed back to radio, again.

I will never want to listen to the radio. I would love to remove radio as an option. I would love to have no fallback as an option. But no, the car just f-n loves the radio and will not stop trying to force it on me.

Oh yeah, and the radio is buggy and could get stuck if I tune into the wrong station. https://www.bbc.com/news/technology-60333765.

This car definitely tries too hard to be smarter than it is. There's all sorts of exceptions that keep the doors from auto-locking when I walk away, and I would turn all of them off, but I can't. Walk away too fast? doesn't lock. Open the rear? won't auto lock. Car just doesn't feel like it? doesn't auto-lock.

And god forbid you hit the unlock button when the passenger has already unlocked it. Anxious beeps from the car for several solid seconds. That is not an error condition!

Performance and reliability have been great though. They just need to stop trying to be smart. They're not.
