Honda Accord VCM



  • well hard to improve something when there isn't a problem.
    The fear mongering on here almost caused me not to buy an Accord......would have been a huge mistake.

    I've read posts here that state how "maddening" it is to see this light indicator go on and off. When driving my 08 V6, I find once I get up to cruising speed, it stays on almost all the time. I've only had it 3 days so it might be another 4-5 days before I can check the mileage on my tank. I have not experienced anything unusual. Whether I'm going 25 or 65, the engine runs very smoothly. I'm happy so far! :D

    Actually, I think we've established that there are some Accords that have a noticeable problem but that most don't. I'm glad yours is fine. :-)

    I was looking at the Honda website, and the 2009 info is up for the Accord. If I am reading it correctly, it appears that Honda has dropped Grade Logic from the Accord -- at least it does not seem to be advertised as a feature. I am wondering whether / how the Grade Logic plays into the VCM issues we've been discussing and why, if true, Honda decided to drop this feature.

    Considering that Grade Logic has been on Accords for well over a decade (my '96 has GLC), I'd be surprised if they dropped this feature.

    Thanks for the heads up about the 09's on their site. Look closely and Grade Logic is still part of the package.

    TransmissionsChoose a quick-shifting 5-speed manual transmission. Or opt for the available 5-speed automatic that features our Grade Logic Control system, which helps put an end to gear-hunting when climbing uphill or driving back down

    I missed it; thanks to all for flagging it.

    Ironic that the Grade Logic is claimed to put an end to gear hunting when many (including myself) are complaining that one of the flaws with the VCM is that it causes a gear hunting sensation.
  • I'm experiencing a vibration in an VCM sedan mostly between 35 - 45 mph and 1500-2000 rpm. It feels like one of those small roadside emergency air compressors strapped somewhere inside the engine compartment. I have less than 600 miles on the car. Dealer says they took several cars out on the lot and they did the same thing. They acknowledged what I was feeling and said that what I was feeling was the active motor mounts. It's quite pronounced and there's no mistaken when it's on. They said Honda techline states no corrective action at this time.

    I do not have the high speed shimmy vibration that others speak of though, and I don't notice the surging either - it's just this low speed vibration. I asked them to swap the motor mounts out. They said they would call me when they have a set of mounts to install. They told me that although they feel strongly that swapping the mounts wouldn't make a difference, they would do it for me anyway. Anyone else getting this specific problem?

    I drove someone's coupe and it does the same thing, but it's nowhere near as noticeable as my sedan - his has over 5k on it now.

    Is this the problem that others have stated has gotten better after a few thousand miles? I know my friend's car now has over
  • golfrskigolfrski Posts: 262
    Are yu sure the vibration you are feeling is not coming from your seat and steering wheel? Also do you feel any vibration between speeds 62-71MPH with specific focus on 65 on the dot?? Dont think "shimmy" when you test, just look for vibration in the traditional sense like out of balanced tires....
  • After dealing with an extensive set of problems on my 2003 Acura CL, I've been shopping around for a replacement. The Accord Coupe seemed like a natural choice.

    For whatever reason, dealer inventory is pitiful in Colorado, so I was only able to test drive the automatic transmission models.

    I4 EX-L: Great car, reminds me of my 98 Accord Coupe, except more like a BMW. I want it in my driveway as soon as possible.

    V6 EX-L: Between 70 and 80 mph, it felt like the front wheels were out of balance. I even got the salesman to acknowledge the problem during the test drive. From what I've read in this forum, the vibration could be related to the VCM. If so, Honda did not fix the problem for 2009.

    I've enjoyed reading about this, and appreciate being steered away from the V6 with VCM.

    Has anyone driven the V6 MT? Any drivetrain problems?

    Just had the tires high speed balances again on my 2008 Accord (we've had it 9 months, this is the third time). Honda now puts on the repair order that the vibration from the car runing in ECO mode is a normal characteric of this model. Too bad the advertising stated that the VCM operation is virtually seamless when I purchased the car.

    A warning to potential buyers of the 2009 Accord, it has the same problem as the 2008. The VCM V6 is not the smooth powerful engine of the previous generation. There are much better cars available for the cost of this car.

    Wow. :cry:

    completly unreal.
  • jam1000jam1000 Posts: 182

    Too bad they didn't put the same thing in their brochures and other marketing and promotional materials. I could have saved myself a lot of money and aggravation.
  • Why Honda would not find a way to eliminate the shimmy/vibration at highway speeds is simply amazing... they have some of the best engineers in the world and they cant figure this out??? makes no sense... and for the dealers to NOW say the vibrationin the V6 is a normal byproduct of ECO/VCM seems crazy.

    I am not sure why the Accord VCM is even having an issue, when this is older technology. The Odyssey van has this.

    If they were smart, they would get rid of the notification of the ECO light, and perhaps give the driver a button to turn off or on the feature. When they wanted the feature on, a simple icon would be nice to let you know that when the condition is right the VCM will engage, but you will not know exactly when it does engage. I am sure some find it annoying for it to be flashing on the dash anyway, and who wouldn't want to feel it switching over. Doing the above would give drivers to be able to take full advantage of the V6, but when they want to be more conservative, then they could simply push the button to engage the feature, then you know that at anytime it would engage.

    Dealers are of course wanting to cover for this dilemma,I am sure it is not the norm of what "Honda" wanted. Dealers make excuses, when "we" the consumer know our cars, and know when something is not right. Hopefully Honda will look at all the cases of this, and are working on this for the 09 models.

    I know if I had a V6, I wouldn't always want that feature on, I would love the option to turn this option off, and wouldn't want to see a light flashing on and off all the time, making me observe if it was working.
  • I started to read with great interest all of the discussions here after I decided to buy an EXL-V6 in early July. I am happy to report that after almost two months and 2,000 miles, I haven't experienced any of the problems reported here. Maybe I am just lucky but two relatives who also own 2008 EXL-V6 haven't experienced any of those problems either.

    Also, the ECO light doesn't bother me at all.

    "Also, the ECO light doesn't bother me at all."

    I totally agree. The eco light is not intrusive at all, in fact if I did not look for it, I would not even know the VCM was activated. For those who don't want the ECO on all the time, that's easy, just stay on the gas!
