Stutter/Jerking With Low Speed Accel. '13 v8 JGC

I've had my used (23k) 2013 Limited v8 5.7 Hemi for about a month now. From the beginning I notice a slight jerking/stuttering when accelerating in low gear. I'm not talking about flooring the peddle and having a lull followed by a burst of speed. I mean when I am accelerating between 4 to 10 mph. It doesn't happen consistently, but it does happen at least once every day/drive. Has anyone else had this issue? I seem to remember reading the reviews on this particular model and seeing some reports of a software update fixing this, but now I can't find that anywhere. I am also getting only about 7 MPG. I knew that this monster engine would be a gas guzzler, and I am in stop-go NYC traffic... But I thought it would be at least 12ish mpg. That's secondary. I care more about the lurching issue. Every time it happens my wife gives me a sideway glance. I hate her judging my mistress.

I don't have any technical knowledge to share but yeah I'm guessing it is also tied to your 7MPG. That is way low - you definitely have a problem somewhere. I have a 2012 V8 with oversized AT wheels and a lift and I can get about 15-16 in mixed driving with mostly stop and go.

Yeah - I notice some low speed surging, especially while going up an incline. It doesn't bother me much, but I intend to bring it up to the SA on my next maint. trip to the dealer in case there might be a software update, etc. Feels like the tranny can't make up it's mind which gear it wants to be in ... Don't know what to say about your low gas mileage though. Worst I've seen is about 11.6 mpg with a heavy foot .... ;-)
