No company can please 100% of people 100% of the time. From Honda's perspective, if VCM is operating normally, what can they do to make the 1% happy? Certainly not give them their money back for buyer's remorse - which is what it appears to them. Can I feel the VCM working? Yes. Does it vibrate, shudder, jerk and shake like the few posters here state it does? NO. Believe me, I'm not trying to belittle all your experiences, but based on the some of the descriptions of VCM operation detailed in this forum, you would think the car is flying apart. Broken motor mounts, wheel/tires out of balance or out of round or some other mechanical problem could be the cause, but these are easily found and corrected. I hope you all find resolution for your troubles, but you may have to face the music and decide that the Accord is not for you, nothing more or less.

Replying to: thegraduate (Sep 23, 2008 10:32 am) Given that everyone is now receiving the same response from their service dept, it's clear that Honda has directed the service departments to state that it is a "normal characteristic" of the model. To anyone who is considering buying or leasing a V6 Accord with VCM, please seriously consider shopping around for another car until Honda gets its act togther on the newly designed Accord and stops with the subterfuge. For those of you who have an older Accord and are thinking of trading up to a 2008 or 2009, consider yourself warned that this is not the same quality of car that you were accustomed to in the past. (I'm not sure it's the same company; Honda owned up to problems in the past and did not mislead customers as they are now.) In addition to the vibration from the variable mis-firing of the engine, there is considerable road noise on the highway and on rough payment so much so that it can be challenging to hear the radio at times. If you do decide to get a new Accord, please take it for an extended road test without the salesman so that you can actually pay attention to the car's driving characteristics. See also Edmund's long term test of the 2008 Accord. In hindsight, I would not have purchased a car that was intentionally designed to mis-fire at certain speeds coupled with a systems that creates noise so that the driver doesn't hear (or is distracted from the sound) of the engine mis-firing along with computer controlled engine mounts designed to re-direct the vibration from the mis-firing. At the moment, there are a lot better cars for the price to put up with a car that is annoying to drive. |

In the absence of Honda doing this, I'm one of those bigmouths who will make sure that not just 10, but 100, of my friends are aware of Honda's disdain for consumers who have gotten stuck with this vehicle.

Replying to: ncjim (Sep 27, 2008 12:07 pm) The cylinders in the Honda V-6 are normally fired at equal intervals (0, 120, 240, 360, 480, 600 , 720 deg and so on). Running the VCM in 3-cylinder mode allows these cylinders to be fired at equal intervals (0, 240, 480, 720 deg and so on). Running the VCM in 4-cylinder mode does not allow these 4 cylinders to be fired at equal intervals (these may be fired at 0, 120, 360, 480, 720 deg and so on), Thus, the engine will potentially run rougher in the 4-cylinder mode than either the 3 or the 6 cylinder mode). A Buick engine ran into a (similar) roughness problem when they converted a V-8 engine into a V-6 engine around 1980 without an engine redesign, with the cylinders firing at unequal intervals (0, 90, 180, 360. 450, 540, 720 deg and so on). After couple of years of roughness complaints, they finally went to a crank offset system to allow the engine firing to occur at a constant 120 deg interval. |
