Any of you guys experience a jerking or knocking back when you start the car and then shift into Drive(D)? Is this normal?

 

Have you let the RPMs kick down?
When the car first starts, it's running around 1900 RPMs.
You should let it run for 60-90 seconds and wait for it to drop to 1000-1100 before shifting into gear.
Are you doing this, or taking off right away?

 

+1 gotta wait at least 30 seconds to a minute for the rpms to lower and for the car to warm up.

 

Yea I do, I actually wait until the temperature gauge increase a little, and it still has this "kick" when I shift into "D". The car only has 6700K miles and I always make a full stop before shifting. Should I be concerned, do you guys have the same problem?

 

Once its warmed up, there's a little kick but nothing to be concerned about.
Its nothing like when its cold.

 

Thanks man. Im guessing the "kick" is caused by the drive shaft engaging with the rear differential?

 

Sounds like it's just at start up which is normal. I'm at 1100 Rpm at start up and 650 adjusted idle afterwards. Sounds like your engaging drive while the RPM's are still above 1000.

 

Yeah, my friend at work also has a G35xS.
We went out today for lunch and took my car. He said that his does not idle as high as mine on a cold start up.
I guess my 1900 is high... maybe something to mention to the dealer on my next visit.
