#375 of 466 Honda Odyssey Vibration
May 14, 2011 (6:49 pm)
I have a 2007 Odyssey EX-L and there has been a vibration in the steering wheel since around 15k and will go away If the tires are replaced but comes back after 15k miles and stays with the vehicle. My vehicle now has 82k miles and it's third set of tires on it , two sets of Michelins and now a set of Goodyear Assurance. The vibration is worse on light acceleration or a grade on the interstate with cruise set at 70 but my dealer says it is tires and the front end has been aligned three times, front brake rotors machined, tires rotated every three thousand miles but problem persists. Honda has velvet glove handled my problem to no resolution. No real diagnosis has been done but to switch tires off a new van and install them on my van nothing scientifically like a Chassis Analyzer or anything has been done to correct the problem. My basic feeling is Honda is concealing the problem or making a decision to do nothing about it so I am seeking input or any information possible about your experiences. I would like to say I have four years of formal school in Automotive Mechanics/Technology and 25 plus experience in auto repair/ maintenance from all levels of gas station attendant to Parts&Service Director of a large Ford dealership. I would particulary like to hear from an attorney with an eye on a class action lawsuit against Honda. The last but ironic part of this message is to the right side of this column is an advertisment for the 2011 Odyssey.

Howdy mastertech4. I've got an 07 Odyssey EX-L. Eighteen months ago I had the torque converter replaced under warranty and it's been fine since then. I did replace the stock Michelin tires with Cooper CS4 touring tires (WOW what a dramatic traction increase, even better than new) at 40,000 miles last year and the brakes replaced all around. We've got about 48K miles now and no shimmy's at all. The one thing I don't let the dealer do is the latest ecm upgrade. That precipitated the first torque converter replacement. It was running fine, and immediately failed after the software "upgrade". I do think there is an inherent design flaw in the transmission, but overall I am very happy with mine.

Likely a case of torque converter shudder. Does the light acceleration occur at around 50 MPH with engine RPM stead at about 1200? If you toggle the overdrive so it is disengaged does the vibration turn off. Do it when you feel the vibration. You may need to play around with this.

I have a 2011 Honda Odyssey EL-X, under 10,000 miles, since the purchase I have an intermittant problem that begins around 35mpm where the car shudders or vibrates for a second or so, it only seems to happen on acceleration. it can happen once of multiple times throughout the drive. Of course when I try to recreate the problem it does not seem to happen with the mechanic in the car. Has anyone had a problem like this. It will happen at speeds over 55 mph as well. The dealer is not willing to spend one second investigating the issue unless I can recreate it while they are in the care. Have been back for service 3 times already trying to resolve.

The software update fixed the issue for most of us. Hopefully yours was manufactured before they came out with the update. Call your dealer and mention this software update. Good luck.

It took me months to be able to duplicate the problem for mechanics, Here is what I had to do and I hope it works for you. Accelerate to 32-35 MPH then ease down to about 28MPH then upon slow acceleration back up to about 32 you should get your shudder. I argued with them for months about that this was the torque converter(they told me it was my motor mounts $950 each.), finally after I bought some Shudder Stop and the problem stopped: when I brought a pile of reports from the internet they finally changed the torque converter at approx 50% charge to me(still pissed about that). Problem solved, never another shudder.
Stay on them and make them fix it at no charge. Look up the lemon law and take it back frequently. Don't let them keep it more than 2 days.

I had the exactly the same problem of vibration. Brought it to honda dealership and waited 2-3 hours. They said they fixed the problem. The following day vibration was still there. They let us waited for 3 hours for nothing. I research online and found Parts inside the transmission has to be changed. I went to another honda dealership and explained everything. They changed it and now very smooth...It is not on their recall to hide the defect of Honda. ......HONDA SUCKS!!! I will switch to toyota or nissan for my next car. Hope this helps

Excessive Engine Vibration with ECO on the Honda Odyssey EX-L and Honda Odyssey Touring
When American Honda introduced the current body style of the Honda Odyssey in 2005, the van had some new refinements. For the first time, many of the Honda vans included a factory sunroof, back-up cameras, and sensors in the front and rear bumpers, that notified the driver if the van was too close to a standing object, which was especially important in tight areas such as parking lots and narrow garages. The 2005, 2006, 2007, 2008 and 2009 Honda Odyssey has a considerable amount of additional room and creature comforts that were only dreamed about in the 1999 thru 2004 Honda Odyssey. One of the most important innovations that American Honda Motor Company incorporated into many of the Honda Odyssey vans in 2005 was the Variable Cylinder Management (VCM) engine which cuts out cylinders when the are not needed, while driving at a consistent speed on a highway.
This is referred to as ECO or ECONOMY mode and it makes these Honda vans very fuel efficient when compared to their competition.
With this innovation of de-activating cylinders that are not needed, American Honda had to incorporate a rear motor mount that would dampen the added vibration of the dead cylinders while in ECO mode. This motor mount is on the Honda Odyssey EX-L and Honda Odyssey Touring models and has been known to start weakening within 50,000 miles. The weakening starts a progression of vibration and buzzing that is especially prevalent on acceleration and when the engine goes into the ECO mode.
The photo below shows a worn rear engine mount. As you can see, there is no air gap (where the arrow is pointing) so the engine block is resting on the metal part of the mount, which is connected to the frame. Because there is no cushion (support), this is where the buzzing and excessive vibration is produced.
The photo below shows the new motor mount installed. As you can see, there should be an air gap of about a 1/2 inch between the engine block and the mount (at the arrow). You can also see the darker rounded area (at the point of the yellow arrow) where the engine block was laying flat on the original failed engine mount.
As many of our readers know, here at Accurate Automotive and Accurate Auto sales, we love Honda and Acura products and we have dedicated both sales and service to Honda and Acura vehicles. With that said, while the ECO mode is a very good idea and has been successfully applied to the 2 wheel drive 2006, 2007, 2008 and 2009 Honda Pilots as well; American Honda should either re-think the design of this rear engine mount on the 2005 and up Honda Odyssey EX-L and Honda Odyssey Touring vans or adjust the ridiculous price of the replacement part . This rear engine mount has a shorter-than-normal life and is not currently the traditional Honda quality that American Honda has a reputation for. Currently, this is a very expensive engine mount and retail cost on this part at Accurate Automotive is $668.00 + tx, installed.
At Accurate Auto Sales we sell high quality Honda and Acura used cars. The photos in this article were taken during the replacement of the rear motor mounts involving two of our inventory vehicles. One of them was a 2005 Honda Odyssey EX-L vin code 5FNRL38775B012737 and the other was a 2005 Honda Odyssey Touring (pictured above) with vin 5FNRL38805B078426. The 2005 Honda Odyssey EX-L had 59,651 miles at the time of engine mount replacement and the 2005 Honda Odyssey Touring had 83,057 miles at the time of engine mount replacement. Management of Accurate Auto Sales simply was not willing to allow either of these vans to be sold to our customers with a faulty rear engine mount. Do you think any other dealer would surrender $668.00 per unit, in profit to protect the next owners best interests in a similar scenario? That is why we say, “Come in and see why www.accuratecars.com is the best place in Nashville and Middle Tennessee to purchase and service your Honda and Acura automobiles”.

Yes, thank you for the valuable information and your true honesty. As a person who had premature engine mount failure and a replaced torque converter (right out of warranty), I can say that any info is a little too late for me and my dozen or so trips to the shop. My Honda van saved my life last week when I was rear-ended by a semi, but I'm taking my money and RUNNING to the nearest Toyota or Ford dealer. A full recall should have been issued, nothing less, and I'm pretty sure that will still happen and I will be lining up for my money back.
