Very annoying rumbling/vibration that occurs in the 1700-2000 RPM range when the variable cylinder management engages. The severe imbalance of running on only 3 cylinders transmits a distracting rumbling/roaring vibration into the cockpit of the car. When I originally test drove the car, I did so in stop-in-go traffic and also briefly on the interstate, and did not detect this phenomenon until I had purchased the vehicle. After experiencing this vibration, I wrote a detailed letter to the president of american Honda regarding my unhappiness. A colleague of his, named [xxx], contacted me but offered no help. She acknowledged receiving my letter and said that it would go on file. I asked if it were possible to disengage the variable management system, but [xxx] said that Honda does not recommend that. I asked if american Honda would allow me to swap by new 2014 Honda Accord ex-L V6 for a 4-cylinder ex-L, but [xxx] said that would have to be between my dealer and me. I will never purchase a Honda V6 again as long as it has any form of variable cylinder management (vcm). I feel that it is important to go on record regarding this matter. I have been a loyal Honda owner for the last 30+ years and have owned 5 new Honda vehicles over that period of time.
