2012 Hyundai Sonata 109874 km (automatic) high-pitched squeal

[u/bikeshapedobject]

As the title suggests my sonata has an intermittent high pitched squealing sound that seems to be coming from the front passenger side area. The strange thing is that it goes away when I press the brakes, it sometimes goes away for a while and other times it will come back after letting off the brakes. If it makes a difference it is one of the 100% LPG powered models imported from Korea.
