I have a 2007 Civic LX (1.8 L 4 cylinder). It only has about 25K miles, and it drives just fine. For the first two years the engine was very quiet and the car idled smoothly. Then, I began to notice more noise from the engine (a slight "chugging", sort of like the sound of a diesel engine). At some point I also noticed an annoying vibration while the car was idling (when warm). The vibration is most noticeable in Drive and Reverse. When the car is in Neutral the car doesn't vibrate as much, but you can still tell the engine is vibrating. I've taken the car to the dealership three times for this problem. So far, the dealership has reset the computer, replaced the passenger side motor mount, and installed software updates. (They said they consulted Honda America.) The vibration and the engine noise are no better than they were before. The service advisers have compared my car with other Civics in their loaner fleet, and the advisers tell me the vibration is "normal". On the other hand, one of the advisers told me some other Civic owners have complained about the same issue. I took the car to a foreign auto repair shop for a second opinion. The owner told me he did not think the vibration was excessive, but he put the car on a lift and looked it over very carefully. He said the torque rods might be worn, but he also said he could not guarantee that replacing them would stop the vibration, and he thought it would be a waste of money to replace them. So, it seems some other Civic owners and I are the only one who thinks vibration is a problem. I realize that as a car ages things become "looser" and you hear more things rattling, but I still think something is wrong. There must be some way to fix this annoying vibration. I don't know if the problem is with the parts intended to isolate the engine vibration from the rest of the car, or if the engine is just vibrating more than it should. I've asked the service advisers at the dealership about adjusting the valves, but they tell me it's too early (25K miles) to do that. There MUST be some explanation for why this car vibrates! Any serious advice would be appreciated. Thanks.
