#387 of 466 Re: 2011 Honda Odyssey Vibration in ECO [ciao888]
Aug 25, 2011 (12:44 pm)
I had a 2006 Oddessy with the ECO vibration at about 35000 miles, they replaced the rear motor mount and the problem was fixed.
I now have a 2011 Honda Odyssey and I have the same problem with 19,000 miles but in addition to the vibration there is a lerch in the transmission as well. The vibration is easily felt under light load while the engine is in ECO just in the zone where it won't bump up to 6cyl. The lerch seems to come from no where and is intermittent but almost feels like an engine miss, although it is not, no codes. The vibration is loud enough that you can hear a growl when on a quite smooth road....
I called Honda of Tiffany Springs in Kansas City where I purchased this and the 5 other Hondas I owned,, they duplicated the problem, and then duplicated it to a lesser degree in a new on the lot car as well. So they called Honda tech support... survey says.. " Known Drivability Issue" suck it up and live with it, no tranny updates or torque converter software updates.
I called customer support, talked to Dave,, told him the story. I sounds very concerned and agrees that it must really be annoying to drive a 38000 dollar car that feels like its driving on rumple strips. So he calls the dealer and tech support... Survey says " Suck it Up" Known issue No Help and all of a sudden Dave isn't so concerned anymore!
At first the dealership said they would buy the car back but now that Honda won't support it they may consider it but I'll get hosed...
There answer, why not see if anyone else is having a problem with the 2011. Honda is on my list how about you?
I have asked the Dealership Managment to step in and assured them that I wouldprovide any addtional feedback from other drivers of the 2011 Odyssey that have found that the vibration is unacceptable.
I was very emphatic with Honda customer support that I will not drive this car for the next 5 years and would be getting ride of it, but that he should the folks know that do risk assessments because I will , put it on Edmunds, You Tube, seek lemon law relief and any other medium to ensure that the driving public is aware that Hondas ECO systems in Odyssey are not what they advertize. The message below is my first message to the general public.

Can you duplicate the vibration as follows?
Likely a case of torque converter shudder. Does it occur with the light acceleration (feather the accelerator) 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. The key is to see if you can turn off and on the vibration by toggling the overdrive.

We had the vibration issue with our 2005 Odyssey. IT'd come and go and after reading all these posts we weren't sure if we should do anything. I had my van in for some other service and they were checking the van and they said they noticed that one of the front engine mounts was cracked. It was about 60000 miles when i brought it in but have no idea how long the mount was cracked. They fixed it for free under warranty. Since that time, I haven't noticed the shudder/vibration in the van. I think they said they wanted to do a s/w update too which i let them do so not sure what the cause was and if its been fixed so its kind of a mysterious enigma.

Thank you for your post, Yes it does, light accelertion while in eco only.
Excellent suggestion with regard to the OD. I'll check it tonight. The reality is however, Honda has said they will do nothing with it, calling it a known drivability issue. My take is this. I believe it is the same type of shudder you would get in a manual transmission when the clutch shudders if you are in a higher a gear then you should be under load. In this case I think it is the torque converter shuddering. All they would have to do is adjust the computer setting to vary the load that causes the engine to switch back to six cylynders... problem is.. you do that and milage goes down,,, make it a factory change and all of a sudden that 27mpg on the sticker window goes away. I don't care about the one mile per gallon, I care about the fact that the vibration is annoying and it doesn't go away.
I would imagine that dropping it out of OD would change that by changing the load factors.. I'll repost when I test it tonight.

I've got a service bulletin on how to check for torque converter judder and lots of documentation that this is an outstanding issue with the Odyssey's and other Honda vehicles sharing the same V6 engine platform. Tell me how your test goes.

Tested it tonight,the transmission does not shudder with Overdrive off in the exact same conditions that would produce the shudder with OD selected. While the transmission doesn't' shudder the rpms are higher which does make a difference in the lugging on the torque converter, and it still does this lerching thing like something is grabbing. Almost feels like and engine miss but its not, I'm sure it converter lockup.
The RPM difference w/o overdrive selected is very significant, 1500 rpms at 75 mph. The engine is wound up, about 3500 or so as opposed to 1950 to 2100.
Thinking about sitting in front of the Tiffany springs dealer with a sign or calling channel 4on your side to see if I can drum up some extra ears. I have seen enough posts about the excuses Honda has been peddling to perhaps get some interest. The fact is though, I've seen enough other posts to know it is usually ineffective with Big Honda... I don't want to carry a torch, just want out from under it...
I've sent an email to Honda of Tiffany Springs GM and Service Manager and they never responded. Without resolution my only goal can be to put enough key words and post long enough to change the minds of Odyssey buyers and perhaps those looking to purchase at the Kansas City dealers.

My 2005 odyssey has exactly this issue since 30,000. Now at 82,000,the problem is more noticeable. This happens when car is still cold, cruise between 35 to 45 MPH on incline. Yes, RPM was low. I never had this problem after 30 minutes of driving. Also, if I turn off o/d, the problem disappears so I am certain,it has nothing to do with engine mounts. I drove stick shift before. When this problem happens, it feels exactly like drove on 5 th gear at 35 to 45 with manual transmission. Given that, I think maybe the problem is fixable with just software change. In some other cars, such as 2001-2003 Toyota rav4, when car is cold and on incline,the o/d has delay shift. That makes engine to rev really high. Early adopters of rav4 hate it so much that Toyota upgraded engine from 2.0L to 2.4L in 2004. Odyssey has 3.5L V6 engine, it shall have enough torque to deal with 5th gear at low RPM. Nevertheless,ECO on EX-L & touring models is a tricky business. I believe the combination of ECO, o/d (5 th gears at low rpm) & cold power trans, (maybe engine mounts have some roles too) caused this problem. I think replacing torque converter will work but will only resolve this issue temporarily. A true fix is to disable o/d until the power trans reaches normal operation temperate. This is done through software upgrade on engine control module which is the least expensive way to go. Well, I guess it probably is not that easy for Honda engineers to come out the best parameters to use. That is why my next car won't be Honda again. For now, I will live with the problem with the work around that was figured out by myself. Shame on you, Honda! I can see Hyundia and Kia will pass u at no time.

I also have a 2005 EX-L, and have been having this problem for over a year. We did pretty much the same thing all others have -- replaced the tires, did the brakes, rotated the tires, several alignments, all to no avail. I am confident that ours is the same issue -- we will try turning off the O/D tomorrow, and I am confident we will have the same success as others. Just adding to the thread here in case a class action or recall is in the works. Honda should know better than this. I did notice on one of the earlier posts an issue with the fuel pump -- there was a recall earlier this year on those, so Honda reimbursed us for the fuel pump replacement we did earlier this year. Hopefully they will do the same with the tranny problem since it is obviously a trend.

I have the same shudder issue on my 2005 Odyssey EXL which has around 98000 miles on it. The dealer quoted around $2300 to replace the torque converter.
I called American Honda to enquire if they would consider helping on repair costs. After about a week they came back and declined any help, basically saying you are out of warranty and there is no recall on this issue. They pretty much hold the line on "we don't know if there is a trend with Ody 2005 having this issue at this time and there's nothing we can do about it".

We have a 2006 EXL/NAV/RES with 94k with the shuddering problem (defective torque converter).
Our Honda service adviser told me not to waste our money replacing it. He sees people come back after couple months with the shuddering again.
Once again, like the class action transmission settlement ('99-'03) Honda chooses to ignore the issue and replace defective part with like kind.
I see another class action coming up on the Odyssey again in the next couple years. It's tough to live with this problem after spending $30-40k for a new car.
