I have a 2010 ML350 with 8000 miles and since day one have experienced an issue (problem) with the transmission wanting to stay in 2nd gear. It happens once or twice a week; when starting to accelerate the transmission will stay in 2nd gear almost to the redline. I am not starting rapidly in fact it even happens while starting off going down my street which is a rather steep hill. It is as if I have a manual transmission and left it in 2nd gear. The dealer said they could not replicate problem thus nothing was done. I'd appreciate any feedback as to what may be wrong. Thx
