I'm doing my best to get used to it, but lately it has been driving me nuts. Seems to be the opposite of everyone's complaint where there is vibration under acceleration.

Vehicle: 2012 TSX SE I4 6 Speed Manual - 46K on OD

Symptom: Above ~2K RPMs there is a vibrating sensation in components in the cabin - Gets progressively worse as RPMs rise - When de-accelerating (RPM's falling, gas pedal is at 0%), in gear or not, there is a vibrating sensation that is apparent in the steering wheel, gear selector, clutch, brake, and gas pedal. The vibration is transmitted through the entire flow of working the clutch pedal. There is no audible noise produced in the cabin. It is not a violent shake, but more of a high frequency vibration similar to the feeling of an electric razor. The sensation is significantly reduced when the engine is under load (accelerating in gear).

I understand that there is an engine 2 feet away from my feet but this is the first time I have ever felt a non high power car (Modded American V8's) transfer so much vibration in the cabin. Being a "luxury" car, I'm having a hard time accepting this as normal. I thought it may be the tires, but it can be felt when the car is barely moving. Can anyone relate or comment on how their CU2 feels in regards to my symptoms? I want to take it in, but the Acura dealer by my are a bunch of pricks that consider this to be normal and refuse to consider replacing any components, even when I am willing to pay out of pocket.

check motor mounts. a shot mount will transfer more vibrations into cabin

Good idea. I'm going to research the topic but is there anything I can do besides simply examining the exterior of it with a naked eye? I'll have to take it to a pro to do the work/diagnostic.

I dont have a TSX, so I dont know what they look like.
for my TL, I could see one "limping and dangling" and the others i had to take a cover off to inspect if rubber is still intact.

Anything is possible but is it common for the mounts to fail with under 50k miles? Thanks for the help btw.

Sure. It's rubber after all .



Best way to check mounts is to have the hood up, e brake on with foot on pedal, have someone stare at engine while you shift from P to R to D. Look for excessive movement from engine

certainly the case for my TL. I think mine failed before 60k miles. (although, my driving habits, or abuse, might have contributed to them dying. 6MT and I drive like i stole it.)

the automatic TL's were eating the motor mounts up even faster!

Thanks for info. I'm going to be probably taking this to Honda instead of Acura. Any reason to be concerned?

Nope
