I got my car back yesterday. i paid $250, Honda paid for rest. The dealership gave me loaner for free for 5 days. they replaced small or lower engine block, ring seals, 3 plugs, etc. I asked them if they think this will happen again, they seemed confident that with software update that it would not. I was wondering if any one after the software change, (2011 or newer) has had this problem.So far it seems to be only in cars prior to this update, such as mine and ioreper.
Right now the car is smooth, i never noticed significant hesitation from VCM either now or previously.

The only hope I can give you is that our 2011 with 13,000 miles has been flawless. However, it is driven 95% city, so it is rarely exposed to the conditions that create problems (long stretches of 3 cylinder operation, i.e., highway cruising). The 2011's also have the piston ring mod and extra moly when delivered. Since the moly eventually washes away, I am going to a high moly oil.

In essence, Honda created needless complexity by adapting VCM, when in fact a 6 or 7 speed transmission would have done the job! We left Honda Accords after our fantastic running 2007 V6 EXL was worn out. That combined with the sneaky de contenting on the bloated 2008+made it an easy decision to go elsewhere. I am not surprised about the reliability issues posted here. on the v6 VCM models.

I don't know about "needless". Blame your government for the pressure of CAFE. In the minivan world, Honda has a 15% fuel mileage advantage because of VCM and that is huge. It's also why I bought a Sienna. But how many of those buyers even know about VCM? They trust Honda to be reliable.

CAFE was the motivation for VCM, but ...they needed the 6 or 7 speed auto first and I believe they would get the same results without VCM's..unneeded complexity. Understand my context with the 4 door sedans as the bench mark. Toyota did just that and have an engine that runs smoothly at all speeds. That minivan "advantage" shows on paper but I'll bet the real world mileage is closer on both and you won't be sucking oil 80,000 miles like many of the Honda's seem to be.

True. It's better to let all the cylinders work, on a higher gear. Low noise, low wear, no vibrations.

Oct 21, 2013 (6:19 pm)
Guess what - Our 2013 EX-L V6 AWD now has the same problem - if not worse than our 2010 Honda Crosstour. Severe floorboard shake at 22mph - 28 - then again in the 40mph range then again around 72-78mph. It's not as bad in S mode - using the paddle shifters.
Honda - Please get a clue - I'm also seeing people complaining with the Acura RDX - which just received the new VCM.

Having owned Honda Accords since 1981, and most receently a 1997 Accord V6, a 2000 Accord V6, and a 2004 V6 Coupe, we bought a 2008 V6 with VCM with great confidence in December 2007. In early 2011, with only 28,000 miles on it, all hell broke loose on a trip from NYC to our son's house in NJ. first the check engine light came on - I stopped and checked to see that the gas cap was on correctly as we had gotten gas. Followed manual and restarted the car - everything seemed fine, then all of a sudden the check engine light came on , the VSA lights, and the transmission downshifted two gears by itself. I tried restarting the car again, but each time, after about 30 seconds of operation, the same thing happened. We limped back into NYC - took the car to Paragon Honda in Queens - the result after several days of examination with the Regional Manager involved - something about transmission input and output modules replaced and the car pronounced "fine". Yeah, drove it home and it was not downshifting slowing down going into corners - came out of a slow turn in 5th , the transmission/engine lugging. I wasted no time - sold it immediately to a dealer in Texas on ebay and bought a used 2008 Acura RL with 18K on it for LESS than the Accord cost new. My highway mileage IMPROVED on the same trips from about 27 to 29-30 with the RL, and NO MORE VCM!!! That thing drove me nuts - seamless changing from 6-4-3 and back??? No way - I felt every change of cylinder management. Now I see that the Accord V6 has lost its recommended status as a used car by Consumer Reports. It is no wonder. Honda has lost me as a customer since 1981 since the new RL has VCM also. I will not own a Honda product with VCM. IF I need another car - my RL has 34,000 miles on it now - I am looking very seriously at the 2015 Hyundai Genesis with 8 speed transmission.
