#2692 of 2720 Severe Engine Shake on 2010 Honda Accord Crosstour with VCM
Sep 13, 2012 (6:33 pm)
We have a 2010 Honda Accord Crosstour - 6 Cylinder - AWD - with severe engine shake at 22mph. My wife says it happens at highway speeds - but I can't rule out road conditions at those speeds. The gas pedal, brakes, front floorboards shake real hard with going up any incline, stop and go traffic, and gets worse as the car warms up. The power drops off as well. The shake gets so bad my 10 year old in the back seat will say - I felt that back here !!
My neighbor and I opened the hood and drove the car down the street - you can see the engine shaking extremely hard at 22mph.. I would expect a little shake - but this reminded me of a gallon paint can shaker.
The dealer has replaced the front axles/CV joints, swapped out the rims and tires, swapped out the computer, and even tried shutting down the VCM - with No change. The dealer said they checked the engine mounts and said they were OK..
I have test drove 8 other crosstours - one had a little gas pedal shake at 22mph -but the others didn't show any signs of it.
The engine doesn't shake if you step on the gas pedal hard. The engine will shake in 1st,2nd, 3rd, or in regular D - so to me it doesn't look to be a transmission problem.
I'm worried about my family's safety - that something may come loose that normally wouldn't because this engine is shaking so hard all the time - putting my family in danger or someone else in danger if my wife or any driving this car looses control because of a failure.
We have been getting lousy gas mileage as well.
NOT proud of my Honda and actually worried about my family - Honda is still trying to figure it out and we don't want this car anymore - since it has been shaking since day one - and worried about a failure putting everyone in danger.
Honda needs to do something about it fast -- I would prefer to have the Honda Ridgeline motor in the crosstour without VCM and I'll bet that the gas mileage will be the same as with the VCM - if not better with less moving parts and less things to fail.

Sorry to read about your difficulties. It sure sounds like the dealer and Honda have given a yeoman's effort to get to the bottom of your problem and that they haven't yet given up so, I'd keep working with them until they solve it or give up. Their intensive efforts and many repairs (I assume under warranty) means that they agree you've got an abnormal problem. It doesn't sound like a VCM issue, but who knows?

I drove our crosstour tonight and man it not only shakes at 22mph but at 72-74mph - just as bad if not worse than 22mph, you can feel in through the seats, gas pedal, steering wheel, and floorboards. The dealer has roadforced balanced these tires several times now with no improvement - even moved rims around ! .. My wife was definately right..
Thanks IndyDriver - I'm meeting with Honda once again on Monday - hopefully will get to the bottom of it - or time to pursue lemon law. .. It's terrible to have a new vehicle and not be able to trust it.
Added features - if your accellerating on a ramp getting on the highway you can feel it in the engine shake in the steering as well while turning on the ramp.
Honda was supposed to be one of the highest rated vehicles - this design has some not so nice features.
Just recently my co-worker is complaining about her crosstour shaking real hard at 72 - 74mph. She just had new tires put on - then had the new tires replaced - still shaking between 72 and 74 MPH.. I'm definately not alone with this problem.

I know you said they were checked but I would take a closer look at the engine mounts. It wouldn't be the first car to leave the factory with poorly designed or installed mounts. I replaced one of the mounts on my Mazdaspeed3 as a performance upgrade. The OE was a pretty flimsy piece. The aftermarket part was carved from aluminum billet.

Sep 29, 2012 (6:27 pm)
Have a 2010 v6 accord, with 75000 mi on it. ~3 months ago started to intermittently have flashing engine light along with rough running engine, brought to dealer and nothing found as it wasn't actually doing it at time of service. 3-4 weeks ago ame problem which persisted and codes indicated the problem from the tsb of 8/2010, that i had fouling of spark plug #3 . Dealer replaced that and updated software. ran fine till yesterday when exact same problems returned with rough engine and the flashing engine sign lit. I am concerned as supposedly the dealer had already updated software to prevent recurrence yet i have it again.

Dealership waiting for response from honda motor usa re: solution and cost. Dealership thinks there may be internal damage which might require replacement of "small engine block" ? I am told Honda would cover fully if car less than 5 years old or if milage less than 60,000. Mine has 75, 000. Unclear thus far if will be prorated or fully covered.
They also mentioned that this problem more common in drivers who have car in ECO mode for greater % of time, ie driving at same speed for extended time on highway. I drive 50 miles/ day same speed on highway.

Yes, highway miles seem to be a bigger problem for VCM. This was noted in the service bulletin. If you want some more ammo on this topic, try googling "Odyssey oil consumption". All of these vehicles have VCM V6s which is why I bought a Toyota minivan this year.

Dealership got response from technical advisor Honda, they agree that lower engine block needs replacement, also need to fix rings ( which are in upper block?). (I am not technically savvy re: engines.)They think lower block problem allowing oil to leak and foul plugs. Estimated cost of repair =$6,000. Honda will cover all but $200-300, which i am reasonably happy with given car has 75,000 mi on it. Worry though that this may happen again. I kept my prior 2003 v-6 accord till 200,000mi, not sure if i will get that from this car with VCM.
I have heard honda hopes software updates will solve this problem but i am not sure if this is proven over time.

Obviously, any Honda owner would be disappointed with an engine that only lasted 75,000 miles. Can you imagine the new car showroom with a big promotion: "Step right up and get your 75,000 mile Hondas!".
It is good to see Honda stepping up on a car that is well beyond the warranty period. I think you should be happy with this action. I'd be thinking about trading it though soon after it is repaired.
'Rings' refers to piston rings that seal the cylinder walls during piston movement keeping combustion elements out of the crankcase and crankcase oil out of the combustion chamber. Note that piston rings were "upgraded" for MY 2011.
All said, I still believe that these "fixes" are merely bandaids on a bad technology. GM learned it's lesson the hard way but Honda seems intent on betting the ranch on cylinder deactivation. It's a cheap route to gain a little CAFE fleet average bump but the problems created by temperature and pressure differentials and who knows what else empirically reduce life expectancy of this engine. Honda began by stonewalling all their loyal customers and have lost many for good. It appears now they are quietly fixing these engines as they fail. They will never know how many people like me never even considered their product when shopping for minivans earlier this year.
