The Jeep is common for developing a hissing noise from the dash area. Many owners notice that this sound is actually from the air vents for the climate control and have reported taking he vehicles back to the dealership to have this issue looked at. Many consumers are returning with reports that the dealer is telling them that it’s a characteristic of the vehicle. This is not the case.
