Have any of you had a customer with an Acura MDX that creeps forward with the transmission in neutral?

The guy says the surface has a rise of 2" in 100' so the car would roll backwards if it were a gravity driven problem...what do you think?





I asked this in "Acura" now I'm trying "Maintenance and Repairs"





Thanks for any responses or theories!|||Are you sure that it is in neutral? It sounds like its in drive with indicator on the "N". I would count the clicks on the shifter to ensure that its in "D".
