Replying to: wertzee (Oct 27, 2008 7:18 am) We all have the same problem. You both have described the issue and conditions in which we get the shudder / riding over washboard feeling under light acceleration in the 1500 - 1800 RPM range between 30 - 40 MPH, up a slight grade. Won't happen going down a slight grade. You both have a 2005 EX-L right? I have 71,000 miles on mine. I went to the dealership today and had a mechanic ride with me...guess what??? IT DIDN'T HAPPEN! How frustrating is that? So the service manager said to leave the car and they'll have a tech take it out a few times. I didn't want them tearing the car apart to diagnose, because they "have never heard of this issue". That would cost me $$$. He said he would go to bat for me with Honda corporate if it is the transmission...My question is if this is a transmission problem, is this just a nuisance or will the car fail at some point? |

Replying to: gmm1 (Oct 28, 2008 6:52 am) If it was transmission the symptom would be the same in normal mode as in ECO mode - also the transmission service tech who drove my car did not think transmission was the cause - not to mention that transmission slip would generate a fault code. To me its like a timing issue - and since there is no timing - only a program, I think its computer related. It wouldn't be the first time a computer needed to get replaced on a car. The other thought is that the hardware devices (whatever they may be) which are used to control the VCM are faulty.

I just saw a different dealer about the vibration. Had a service rep ride with me. He said that he felt the vibration and stated it kicks in when overdrive kicks in. He didn't know if it was normal or not. When we returned to the dealership the service manager handed me a printout stating that they "couldn't reproduce the problem". The rep absolutely said that he could feel it. When I questioned it they "dummied up" On the way home I got a call from American Honda on my cell. They said that they opened up a folder on my car and were going to send me to the dealer that I just left. What's that about? If they didn't know that I was just there why did they call my cell? I called my wife at home and they hadn't called my home phone. American Honda suggested that I ask the original dealer to schedule a test ride with their factory rep. which is supposedly on the property once a month. My opinion is that they don't want to do anything about the problem. I only bought this car six weeks ago and it only has 3000 miles on it. I have to drive it for at least five years hating the way it drives. Also, I feel compelled to buy an extended warranty now. With this vibration something has to fail eventually. |

Had the Factory Rep ride with me today. Vibration kicked in right on time. He agrees that he feels it. States that it's normal and had me drive a 2009 LX which did the same thing. He tells me that they all do it and Honda knows it. He states that there is no fix for it or he would have it fixed. He claims that it will not cause a failure and there is no wear being done. If there is a drive train failure after the warranty runs out and it's been serviced on schedule he claims that Honda will "help me out" with a good will service. He didn't recommend the extended warranty. I can get the ext. for a thousand dollars six yrs 120,000 miles. I think it's probably worth that for peace of mind. My mistake was not test driving this car. I felt that it was a Honda and brand new. If I had it to do over I would have and probably not bought the car. Now I'm stuck with that problem for at least four years. Don't know if the lemon law would apply in this case as it's not a safety problem.

i am pretty sure mine does this as well. thankfully, it is a lease and I am not stuck with it. as user friendly as it is, it is a big pos. It will be my last Honda.

After reading most of your comments on the Vibration, It Seems to be comming from primarily two causes.ONE is engine Vibration cause primarily by engine and only varys with the speed of the engine. and TWO: Vibration from Speed of vehicle and varys with the speed of the vehicle ONLY. ie Wheel bearing, Drive train, etc. Try to determine which Vibration your have. The Primary, "less noticable" vibration I believe we are all feeling is caused from the VCM "feature" on the engine of EX-L and Touring Models. It will always occur when engine is not required to put out much power. Under most conditions the motor doesn't really vibrate (if your engine mounts are good). However, In VCM Mode it is running on 3 cylinders and will shake because it is now out of balance, similiar to removing 3 spark plugs out of your engine. There is no way an engine will run as smooth in this mode. However, There should be NO Vibration, EVER (no more than any other car) from time you start your car, idling in the driveway, running down the hiway or full excelleration when your Motor Mounts are GOOD. Bad mounts however, will cause the Motor will vibrate in one or all of these conditions and Need to be checked, replaced. If they are bad and your Van has ECM the Vibration Will be magnified severly. TESTING MOTOR MOUNTS: (THIS CAN BE DANGEROUS SO BE VERY CAREFUL TO KEEP FOOT ON BRAKE or have dealer check them). 1st Set Parking Brake. I find you can do check engine mounts with the help of a friend(standing on side of vehicle) to watch the engine move while you operate the van. Raise the hood up, Start Engine, While pressing HARD on the brake Put the Van in Gear and gently press on accelerator (put engine under load) till engine starts to twist forward or reverse, your helper should be watching the motor right now, Engine should twist a little when you do this, that is normal. Check Both Drive and Reverse. IF you notice motor RAISE UP a couple inches, and drop back down when you left off the accellerator, then the motor mount under that part of the engine raising up is most likely the problem. On my 05 EX-L the Back mount was shot and the whole engine raised up a few inches when doing this in Reverse. After Confirming Bad mounts and replacing, the Vibration should NOT be felt after starting the car or driving it. Most mounts are around $65. the rear one is $440, the one that took care of my problem. Not sure if we can eliminate the "drooning" sound that is only generated by engine in VCM mode, when engine is under "low" load condition. Perhaps get a Honda van that doesn't have the VCM "Feature". However, VCM is also supposed to be getting us better gas mileage when in this mode, ie: running on 3 cylinders. If anyone Knows how to DIS-ABLE VCM Mode, Please let us know ! The gas mileage increase may outweigh the Vibration.
