We replaced our 2020 Hyundai Palisade’s engine and there is a hissing noise. Very odd as I thought it was the tire, but the pressure is staying the same. It’s on the rear passenger side. Car has been off about 10/15 minutes and we still hear it. It’s gotten quieter though. Nothing smells and I just can’t locate where it’s coming from. Any thoughts? Shop is closed until Monday unfortunately.

Thank you!
