Whenever I turn off my Ford Focus, there are varying intensities of shuddering - like the engine is struggling to turn off. You can feel the whole car shaking a bit. It normally lasts half a second to 2 seconds or so.

Does anyone have an idea of what this may be / caused by?

DCT or 5 spd MT?

It has the DCT.

DCT... Ah! What can I say, it's not normal but according to Ford it's working as designed. Good luck!

Right, but why would the DCT affect the vehicle that way in park?

How often does it do it? Can you describe the different intensities of shuddering? Does it happen after long drives, short drives? I highly doubt it is something major to be honest.

Pretty regularly, especially after my drive home (~15 miles). I'd say 90% of the time. The only variance is really the intensity / length of the shuddering. Sometimes it is only for a split second, other times it lasts up to two seconds or so.

Are you getting your gas from a cheap 2nd tier place? It could be "dieseling" a little.

 

[Shastic]

Nah, gas should be fine. I'll try a higher octane .. Using 87.

Where exactly does Ford state that it is normal for the car to shudder when turning off the engine?

That's not possible.

The Focus (like virtually all modern cars) has fuel injection that is electronically controlled.

I want to look into this further. Please send me a private message with your VIN, mileage, best daytime phone number, full name, and dealer name/location.

Alright, sent you the info. Looking forward to your reply.

 

[Shastic]

Alright, I'm going into the dealer this morning. I'll let you all know how it goes.

I grant you dieseling is mostly gone now that carburetors are extinct but sputtering on shutdown can still happen. Did you consider that he may have a faulty injector that is allowing a small amount of fuel to enter the combustion chamber after the engine is switched off? The OP did not mention his mileage but what about a carbon deposit causing a hot spot? Direct injected engines are no stranger to carbon.

 

[Shastic]

So they can't recreate the problem, but it only happens after driving it several miles... They want me to drive out here, pick up a tech, take him for a long drive, and hope it happens so he can see it... Instead of just taking my word that it happens. It's a big waste of time for me for something that might not even get resolved...

 

[Shastic]

Figures that it does the shudder after I drive home and am turning it off. I need to setup a camera and record it I suppose.

Don't read into this, but was your last car a 4 cylinder?

 

[Shastic]

Not my last one, but I have owned two Civics and one Corolla.
