Just Leased an 06 with the 3.7L, have put about 300 miles on it and love it.  But I have noticed that going up small grades, if I don't push it to downshift, it will start to jerk or pulse.  I have not pushed the vehicle at all thinking about engine break-in and all.

My question is, is this semi normal - owing to engine break-in?  Should I be taking this up to the dealer for diagnosis?  Opinions?  

Thanks in advance
Don

Go to the dealer...just to be sure.  It's under warranty and it's probably early enough if it was that bad you could trade it in if needed.  

3.7 is a small engine for the new GC,210 hp for something over 2 tons,hate to think what that engine in a Commander's like.
