Worn engine mounts can lead to unwanted engine vibrations being transmitted to the body, most commonly with the engine idling and the transmission in reverse. Replacing the worn mount(s) should correct this concern.

Same low fequency vibration in reverse and during deceleration. Could not explain it but it's was always worse in the morning when the engine was cold. Noise was audible and vibration was felt in the cockpit but outside the car all seemed fine. Suspected the passenger side motor mount was broke and an inspection showed the the engine had settled onto the mount support and was actually "shorting" the motor mount as an isolator. $400 parts and labor later the mount was replaced and all problems were gone. Probably should have taken on the job myself but I did not have any extra time available for when the first unexpected "issue" showed up. All is well now. Wanted to leave this update as I see many owners suffering the same noise and vibraion symptoms. Maybe one day Honda will classify their mount as a design/mfg problem and reimburse all of us like they are currently doing for the sun visors that break on everyone's Civic. Hope this can help someone else.

My 2007 Honda Civic had the same symptoms. Vibration and noise were more evident when the car was cold. Had the right side motor mount installed yesterday, and it seems to have fixed the problem. Also had the visor replaced a couple of months ago. Rather disappointed with Honda.......
Had to replace the engine mounts at 36k miles ($600! Non warranty repair). It would rattle and growl, usually in the am, when I put the car into reverse. The Honda dealer initially couldn't find anything wrong, but when I had them keep the car overnight and test early in the morning, they identified the Engine Mounts as the culprit. Not too impressed.

Exact same problem with mine. My car is an EX 5 speed. It has made a loud popping noise from the day it was new if under heavy deceleration and reversing quickly. Mine finally failed and made the rumbling and knocking over bumps when it was cold. These were faulty mounts from the start and Honda know about it. Here is the TSB. #06-060 I replaced all the engine mounts including the torque struts so I wouldn't have to mess with it again. The passenger top mount would have fixed the problem by itself though. I used to wrench as a Ford tech. I understand All companies have tsb's and little issues but after the rear wheel bearings, sun visors, and now this mount that I footed the bill for even though Honda knew they were faulty even at the time of assembly, I would not consider ever again for my future cars.

The same vibration & noise when cold and sometimes on reverse. It started about 2 months ago and it is getting louder and lasts longer. I will take to the dealer to check up.

The car started the growling , loud vibrating noise at about 60,00 mi.couldnt afford the repair at the time and will no longer use a honda service department. four mechanics later and it was finally diagnosed...A rubber part of the motor mount assembly on the passenger side collapses for no apparent reason allowing the motor to vibrate.

Exact same problems and descriptions as all other reports (including the visor)! Just got a call from the service dept. at the dealership. Side motor mount is broken--still under warranty, so no charge.

Same problem but have not been to the shop yet. Rumbling also appears on deceleration. Definitely thinking motor mount(s).
