#450 of 466 Honda odyssey vibration 45-50 mph
Jun 23, 2012 (8:41 am)
Recently I had a Honda Odyssey mini van with a weird viberation at 45-50 mph. The dealer did the motor mounts all four wheel bearings, sparkplugs, and a rotate and ballance and was still not fixed.
REPAIR; I THEN PUT THE VEHICLE ON MY RACK AND ACCELERATED IT TO 50MPH WHILE I HAD ANOTHER TECH EXAMINE THE SOURCE. THE LF HALF SHAFT (AXLE) WAS SHAKING. I REPLACED IT AND DROVE IT AGAIN PROBLEM SOLVED.

I have a 2007 Odyssey with 130k miles. In my case, I recently had timing belt, cv joints and motor mount replaced. We live in Fl where there aren't too many hills. On a trip through Ga I noticed the described vibration in Eco mode. My observation was that during acceleration up a hill (not Eco mode) everything was fine. Real-time MPG meter is showing just over 20, which isn't too bad for going up a moderate hill. After cresting the hill, the engine shifts into Eco mode and mileage jumps to over 40MPG (this is expected since we are basically coasting). About halfway down the hill, the is a definite "shift" in the engine behavior. Mileage drops to approx 20MPG while going downhill(!), and vibration picks up substantially. It feels similar to going down a mountain and downshifting to use engine braking. When starting up the next hill, it remains in Eco mode for a few seconds and the mileage drops to 10MPG in Eco mode! When the Eco mode turns off I am again seeing 20+ MPG.
To make a long story short, I get 20+ MPG going uphill when engine is firing on all cylinders. When Eco mode kicks in, I get <20MPG going downhill, with seemingly excessive vibration. I have had this 2007 Odyssey for four years and have never had this issue before. Overall mileage for the trip is approx 10% less than it was a few months ago. Why would mileage in Eco mode be worse than in normal mode?
#452 of 466 Is this the same issue

Looking at buying a 2008 EX-L. This thread has made me leary. It has 97000 miles on it and seems to be in great shape. Having a mechanic check it out Monday. What brought me here was that at 70-75mph it felt like the TC would engage/disengage kind of randomly. Not a shutter/judder but more just felt like it was shifting. Is that normal with the eco stuff? Is it the Variable Cylinder Management? I really like the car, I just don't want to buy into a $4k tranny problem.

What would you risk it with the class action lawsuit due to TC issue? Should class action be successful would you be covered?

Our trouble-free 2006 EX-L has 157k miles. Based on our experience, that's the VCM kicking in, then releasing. If you hit the gas a bit and get it up past 75 then the VCM disengages and the vibration-sounds go away, for us. I sometimes wish there was a disable switch on the VCM so when going at highway speeds over 75, it would not try to turn on.

Wondering how your odyssey is working currently?
We have 2006 134000 miles, shudders on occasion from 20-40 mph. I have noticed in cruise control going down hill it does not down shift.
I love my Honda and want it to last a lot longer.
Did you have the PCM Update? It sounds like some people think it is better without.
Thanks for any replies.

Traded my piece of s... 2012 Osyssey in for a 2008 Meecedes Benz Gl450. Couldn't be happier!
NEVER to own Any Honda again!
Happy trails to you.

The PCM update was necessary for my 2007 Touring. I had already gotten a new torque converter and the same issue was coming back. Every now and then I get a shudder around 40-45 mph but it is pretty rare. Going on 110k now and running great. We love our van.

Can you make the shudder happen like I do, I set vehicle at 80 -85 KM/H and feather the accelerator to maintain speed, works best on sight incline. This is on a 2010 Odyssey. Anyone know about progress on the lawsuit that was filed for this torque converter shudder?

My 2007 EX-L is north of 65,000 miles and I just took the kids down to Ft. Lauderdale for spring break (from Chicago) It's still running like new, had the torque converter replaced at about 27,000 miles and everything is perfect. Averaged 30.29 mpg for the round trip. After the converter was replaced, I refused to have the "update" for the PCM and am really glad, I heard other owners had more trouble after the updates.
