Replying to: robertsmx (Nov 08, 2007 5:40 pm) It can be felt ALOT. its ridiculous and my prediction is MANY more unsatisfied V6 owners will come forward. The vibration is very noticable and the surging is uncomfortable. Having a "clue" comes from experienceing the issue that others and myself are feeling. Your lucky that you have not had this issue,thats great. but the new engine has issues,, plain and simple and people need to be aware before they buy. |

Replying to: pat (Nov 08, 2007 6:12 pm)  yes indeed I am distressed as would anyone spending such a great deal of money. and I appreciate this forum to discuss the issue and continue the dialog. I am let-down. Honda should have done more testing and homework here on this new config. It is becoming painfully obvious that I am not alone and as the cars begin to hit the streets in greater numbers, the issues, posts and concerns are mounting.. I am hopful Honda reads these as well. I will ceratinly point them to this and all the other forums for customer data. As the service manager at my dealer said, "the car is so new that they havent seen many reports yet".." "they expect this to become a more widespread concern", and that was a comment from a Honda Service Manager!

Replying to: golfrski (Nov 09, 2007 4:30 am) The Accord Sedan’s V-6 features the latest generation of Variable Cylinder Management™ (VCM®) technology. This system can activate and deactivate the engine’s cylinders as needed to meet the demands of both acceleration and fuel savings. When maximum torque is required, all six cylinders are firing. During steady cruising speeds , VCM shuts down one bank of cylinders. In this mode, the audio system’s Active Noise Cancellation™ (ANC) function generates out-of-phase sound waves to cancel out any undesirable noise that may be due to the harmonics of 3-cylinder operation. As cruising speed increases the engine moves to a 4-cylinder mode for extra cruising power. To help keep engine vibration from reaching the cabin in every mode, active engine mounts automatically adjust their firmness to help absorb energy. The transition between the three operating modes is completely seamless and goes unnoticed by the Accord’s passengers. This is misleading...

Replying to: golfrski (Nov 09, 2007 6:07 am) Was going to look at new accord V-6 as replacement next year when TL lease is up. This really sounds like a problem. For time being this sounds like the emperer's new clothes. This hasn't been made public yet. If this gets out, it could be similar or worse than the auto transmissions on the V6 Camry. Remains to be seen. If I were buying now, I would opt for the tried and tru 4 cylinder

Replying to: golfrski (Nov 09, 2007 4:30 am) Several of these guys make a point of knowing its working only when they see the dashboard light. At least I know where they got the word "seamless" from: right out of Honda! I re-read the Edmunds full test of the EX V6 sedan and it mentions that nobody in the cabin could detect the VCM operation. I am glad that Honda will be involved. It looks like only some of the vehicles have this problem. Seems like a "bug" that Honda has a responsibility to fix. Let us know what Honda says. Good luck! |

Replying to: hpowders (Nov 09, 2007 7:34 am) The early adopter, first year buyers are the one's I will really listen to on this, not the professional reviewers. This is exactly why I refuse to buy a first year model of anything - cars, or anything else. (NOTE: However, my wife did! A 2007 Camry, and we are paying the price on that miscue). If there is a problem, Honda will jump on it quickly.

If you read most of the "professional" reviews of a brand new car, I've noticed that they will always tell you what is good, but seem very reluctant to say what is bad. Look at the review of the newly-redesigned Malibu. They tried as hard as they could to be positive - and apparently the car has some positive aspects. But, reading the article, it frankly made me glad I bought an Accord. Also, many of the first test drives do not necessarily include long-distance cruising. If you have the new Accord v6 on a track, or if the test drive didn't include an extended period of time on an open road, I doubt the VCM issues discussed in this thread would be noticeable. Of course, this doesn't discount all the professional reviewers who have noted that the VCM is "seamless." But, it may be a reason to give at least equal footing to those who have actually started giving these cars considerable windshield time
