Low speed shudder

[cyberdude86]

New to the GT AWD from my 2.0T RWD and I seem to have car shaking amounts of shudder in the drivetrain at 20mph almost every time I drive.

When driving from a slow turn or from a complete stop accelerates fine, then slowing due to traffic and maintaining almost constant speed of 20mph will induce shudder.

If I accelerate or brake the car the shudder stops. It seems to be in comfort and smart mode so far as this is a fairly slow speed for sport I am not sure if it also occurs.

Anyone have any advice or experience the same issues?

Being sensitive to such manifestations myself (on the lookout for anything like it), my first suggestion is that it's a normal "complex machinery" kind of sympathetic vibration, like a harmonic, between mechanical systems. How noticeable, realistically, is this "shudder"? Would someone just riding with you be able to notice it?

 

[cyberdude86]

Yes, my wife did notice it. The shudder seems to be around third gear shift point when it occurs.

Have you tried other gears at c. 20 MPH? Hold the gear with the paddle shifters. Maybe the "harmonic" only occurs at that speed and 3rd gear. Stranger things happen.

I know this thread is somewhat dated now but I have also experienced a low-speed shutter that seems to be related to the transmission when taking off from a stop or driving at low speeds. Sometimes it’s a shutter between one - two shifts and two - three shifts. I took it to the dealer and they couldn’t replicate it despite my wife being able to notice the same problem. It doesn’t seem normal. I’ve never had another vehicle shatter like that. But it could also be something like an ignition issue.
Did you find a resolution to your shutter problem?

No, the dealer could not replicate. I was able to narrow mine down to 4th gear and the mode is irrelevant. It will happen in manual at 2k rpm or auto at very low rpm.

Thanks for the reply. I’m going to try the dealer again and see if I can demonstrate it for the tech.

I was going to comment before writing this post, but I've had this issue but believe it's tied to my transmission dying. Shudder when in stop/start traffic slowly crawling. Car feels like it is about to stall until I break or accelerate up. This happened about 14000km's ago in a very bad situation but never occurred again until recently, but now transmission is failing so that may be cause.
