As someone who just traded in their 2019 Mazda CX-5, this doesn't surprise me at all. I couldn't wait for my lease to end. The car was great, but the infotainment system was horrible. It would take 5+ minutes to boot up from a cold start during which time you couldn't change the volume, mute the radio, change inputs, or even change the station. I learned quickly to always change the station off Howard Stern when exiting the car in case my daughter was a passenger on the next trip. On long trips you would have to three finger reset the head-unit because it would just stop responding, play at full volume, only play out of one channel after a GPS announcement, and other random oddities. I brought it back to the dealer multiple times to get firmware updates only to be told "Yeah that's how it was designed".
