So my 2013 GL 450 has a little over 40k miles and is still under original factory warranty; I bought it about five months ago and have brought it to two dealers complaining about the hesitation issue. One dealer gave me the dreaded "Can not duplicate" lame excuse while the other one cleared out the computer memory. I still experience the hesitation & it is somewhat dangerous as it happens pulling out into traffic I get a throttle lag. Has anyone else experienced / solved this issue? Thanks in advance.

I had a very little hesitation issue and it also jerked very slightly when at a stand still without pressing the brake pedal or gas. It turned out to be the tumbler flapper valve arm thingy.

An ecu tune will help and also give you around 150 more hp.
