i have a 06 mark lt and it has the same vibration problems, they reflashed the pcm like 3 weeks ago, it still occurs alot, but occasionally it doesnt do it now. my vibration disappears when i put the car in park or neutral, but when its on drive or reverse thats when i get it, and i feel it in the brake and accelerator pedals,

about the engine dampner thing, can i just ask the dealer to put one on??they so far have been nice to me, i guess since its lincoln, and i feel bad being annoying, but these stupid problems shouldnt be happening to brand new cars, my power sliding rear window sometime doesnt work initially when i start the car until like 5-10 min. pass, my a/c has turned off like 6 times by itself since i got the truck 2 months ago, the chrome pieces that are going around the entire truck are beginning to fall off too (they ordered new ones for me, i just gotta take it in) but this is weird stuff here, and its B.S. for new vehicles

 

so far whatever they did the last time has worked for me. I'm going to keep my fingers crossed for awhile though. I do know that I will never go back to the dealer for service unless I absolutely have to.

 

Well excuse me that I don't spend my whole life here.

 

Some vibrations may be normal, it all depends. I've never heard of an engine dampner in my neck of the woods, but I suppose if a inherent vibration in the engine was transferring itself along through the motor mounts, the frame and into the cab, yeah it'd make sense. Ford's built the stiffest and strongest F150 chassis ever with these trucks, and as such, they'll tend to amplify noises and vibrations that would have been ambient in an older "more flexy" chassis.
