I recently had the Cruze recalled performed for the fire hazard due to oil on the engine under pan. On a 400 mile trip I experiened a reduction of about 4 MPG, not wanting to believe this I checked on my 400 mile return and saw about the same. Has anyone else noticed this? If I had know this I would have skipped the recall. I think an easier way to resolve the oil and fire hazard is to affix the under panel with hinges and when the oil needs to be changed the panel can be dropped down and cleaned and put back. I have tried to get the panel put back, however GM has modified the part and with a new part number. I inquired about getting the piece cut out of one of the Cruzes in for the recall and was told they could not do that. Does anyone know the original part number and if there is a place to get one. My only other choice is to try and find a Cruze in a salvage yard.
