Models:2003-2005 HUMMER H2



Should a customer indicate that they detect a propane type odor in the vehicle, one possible cause could be a sealer skip in the rear wheel house area that could let the rear axle vent vapors find their way into the passenger compartment. Remove the rear wheelhouse liners and reseal all seams, particularly a cavity in the front upper outboard area under the fender flange.
