Bump right after starting

Sometimes about 3 seconds after I start the engine I feel a bump almost like someone bumped into me. It seems to only do it when the engine is warm and not all the time. Anyone else experience this?

Re: Bump right after starting

I experience this as well, but only after the car has been parked for several hours in the parking garage near my office. Dealer said they "couldn't duplicate the problem" so I shouldn't worry about it. I'm worried about it.

Re: Bump right after starting

Same thing (or similar) happened to me the other day. Started the WK2 (V6) and felt a slight jump almost like it wanted to shut off but turned back on in a split second...like it missed. This happened right after I hand washed my Jeep. Maybe someting got wet while rinsing the heck out of it?

Re: Bump right after starting

What a waste of time, the dearler had my the truck for two days and can not fine the problem with the bumping, they told me they made some adjustment to the transmission but the bump on start up is still there.

Re: Bump right after starting

I turned off Hill Start Assist and the problem has not occurred for me since. Could it be that simple?? I sure hope so.....
