Yes, in millions of millions of cars. It power most of the HMI systems in cars, except some newer ones, which are based on Android Auto and very view exceptions based on Windows Embedded/Auto.
This. My car (Porsche Panamera from 2013) runs QNX for its nav+soundsytem. I can stream from bluetooth or use a jack plug but I don't bother: the car's got its own storage for music and, notably, the system takes both .mp3 and .wav files, but not .flac files. So at home I play .flac files but for the car I convert my music to 320 kbps .mp3 (I think I can put about 5000 320 kbps .mp3 in the car). In 2013 Porsche was still putting HDD and not SSD in their cars: some people do the upgrade themselves to a SSD but in my case that would void my extended manufacturer warranty (which I plan to extend up until 15 years / 200 000 km).
Since then, for newer models, the manufacturer has moved the nav+infotainment to Apple's iOS CarPlay. I don't know if QNX is still used for other stuff (like reporting the oil level / warning messages etc.).

My Ford has had both. As a 2015 model it shipped with MyFordTouch which ran on whatever Microsoft was calling the automotive branch of Windows CE at the time (AutoPC?) with a UI built in Adobe Flash.
2016 and newer models got a QNX-based platform with a HTML5 UI under the name SYNC 3, and the newer SYNC 4 variants are derived from that.
I upgraded my car with parts from a 2016 model a few years ago because Sync 3 could do Android Auto and CarPlay where MyFordTouch could not.
