Honda Accord CVT Problems

    My new car does the same thing. Have you found if this is a defect?

    I'm experiencing exactly the same vibration when reaching 50 to 55 mph @1800rpm. Took it to the dealer this morning. After test driving with the technician he was able to feel the vibration and replicated it at the shop. He just called and said he contacted American Honda and spoke to one of the engineers and they say "its a normal characteristic of the car. Its a gas saving feature" I am not happy with the answer. Honestly it is very annoying and not expected on a car of that caliber. For what i'ts worth and I am writing to American Honda to document the issue.

    Lemon Law ?

    Lemon Law applies if there is a problem with your particular car, and they can't fix it. Not if all the cars have a certain standard feature (vibration because of 3 cylinder operation of a 6 cylinder engine). VCM was never a secret. They even use it as a marketing tool (it beats me why).

    Before buying my car, I rented a similar one from a Honda dealer, for a 4 hour test drive. I drove it in the mountains, in the city, on the highway. I even had lunch with my wife, while looking at it in the parking lot. If you keep your car for 10-15 years, like myself, it's worth paying for a rental. It wasn't a new car, but it was the exact trim I later bought. The dealer doesn't care if you put miles on a used car.

    The vibration is clearly evident in my car at all gear-changing speeds. Between 55-60 is horrible. If I set my cruise control in this range, the car shifts in and out and causes the vibration to kick in and out. Drives me crazy.

    Is everyone here that is reporting these vibrations driving with ECO on or off?

    I have a '13 EX-L V6 Coupe and I've never run into any vibrations - not in any RPM band or on surface streets, freeways, parking lots, etc.

    The only thing I've noticed is when I turn off ECO I can feel the car switch over - I wouldn't call it a vibration, but it just comes back to life.

    I ask about the ECO mode because maybe it's trying to drive on 3 cylinders as much as possible if it's ON - which includes slow stop-n-go urban driving. Just a thought, idk.
  • Be fortunate that you avoid the vibration!

    I think you are spot on. I was told by a Honda technician that the ECO mode favors the 3-cylinder operation. So, when you disengage it you may notice an immediate difference if it changes to 6 cylinder mode. However, in normal "Drive" the 3-cylinder mode will also engage automatically but perhaps not as much as when in ECO mode.
  • I went on my first extended highway trip in my Accord V6 for about 150 miles. I must say that the highway experience was much better! I averaged about 65-70 MPH and got 37-38 mpg. Quite impressive. Although I noticed when the 3-cylinder mode kicked in, it was much less pronounced and it didn't really bother me.

    However . . . at lower speeds on level ground at constant speed, the vibration @ 1800 rpm is quite noticeable and annoying. I do not accept that this should represent "normal operation" for this automobile. The problem is further compounded by the fact that the Accord V6 seems to like to hang out at this RPM so it does not happen once in awhile but rather frequently. Drives me crazy.

    If other owners of the V6 are not experiencing this, is it possible it is only present in certain cars (e.g., a certain production run?)

    Just out of curiosity what range are your vin numbers in,last 5 digits,for the
    V6 cars. Under 5000,10000,15000,20000.
    These are sequential vin numbers, lower number the earlier the production,
    I4's are up over 100000 now but the highest v6 at local dealers, around 23000.
    20000 and up would be pretty current production.

    The previous generation (2012) V6 engines didn't have VCM on manual V6 coupes. Is your coupe manual or automatic ?

    Also in 2013 they kept the V6 manual coupe without VCM:
  • My VIN is between 10000-11000.

    On today's commute the vibration is noticeable from 1000-2000 RPM, with the most vibration at 1700-1800 RPM. Believe me, this cannot be normal operation.

    Go to another dealer, ask to test drive an identical car (like a potential buyer). If it vibrates the same ... it means you bought the car of the future. I wonder what people will drive in 50 years ...

    I just picked up my exl v6 sedan yesterday,vin over 22000,made around Jan 24 so it is fresh off the production line. I took extedned test drive over 70 MPH,drove it to work today and back,low speed roads. The only way I can tell the vcm is on is when the MPG shoots up, dont feel a thing,so far less than 100 miles on it.
    Hope this helps.

  • The reflector above the Highbeam/DRL halogen bulb is showing signs of heat related damage with less than 800 miles on the odometer! Those of you with a '13 Accord, that uses the highbeam as a DRL, please inspect your reflector while the highbeam light is illuminated. Let us know if you see any haziness or cloudiness on the reflector, especially above the bulb. I'll post a picture of mine as soon as possible. Thanks.
  • Thanks Old Mike -- This is helpful.

    I have found that my car performs very well at highway speeds over about 65 MPH (and over about 2000 RPM) -- very smooth. The vibration is most noticeable at slower speeds (30-60 MPH) and most prominently at 1800 RPM. Since you do not experience this, I am beginning to believe that the vibration issue may be with my vehicle -- not the entire production of V6 sedans. However, I did note that some others have mentioned the same issues as I have.

    I only have a few hundred miles on my 2013 Accord V6, and I do not feel this vibration. If I keep everything quiet I can kinda hear a difference when it flips over to 3 cylinder and, as Mike posted, I see the gauge.

    I'm curious, just in case I come across this in the future, how distinctive is this vibration you are feeling. Is it a drastic, no doubt, something is not right feeling or is it minor? Also, was it always there since you purchased the vehicle?
  • The vibration produces a low rumble and shake that is heard above fan noise and audio programs such as CD playing at even moderate-high levels. It is also felt in the steering wheel and accelerator pedal. The front passenger also hears and feels the vibration.

    I own a 10-year old V6 Subaru Outback with 159,000 miles on it. If it made this noise I would take it in for service before the next oil change.

    Does that help?
  • No, I have not experienced any rumble or vibration like that. I did notice someone made mention to vin's and mine is over 20000. I have no idea if that makes a difference. Just curious, when did this start (mileage).
  • Noticed the problem in first few weeks. I was still on my first tank of gas.

    My VIN is around 10000
  • Curious what the dealer will charge for oil changes using the expensive 0W-20 oil ($7 per quart at WallyWorld). Many OEMs are using 0W-20 oil now.
