Noticed a shudder with vehicle during 1st week of purchase. Thought it was a little weird since being a new car. Assumed that it was an isolated incident with regards to break in of vehicle. 2nd week of ownership on my way to work, noticed the shudder multiple times during stop and go traffic. This shudder later transitioned into a knock or pinging of some sort while jerking and accelerating on its own without any driver input. Very scary at this point...got off the freeway and parked then turned the vehicle off. Upon start up, vehicle still idling violently. Had to get to work so just braked most of the way and drove with added caution. After work, car behaved normally on my way home with econ and air con both off. Shudder is still present to this day during light to moderate acceleration at 30 - 40 mph. I am fearful of using the econ and air con together as this worsens the problem. Honda and the public needs to know about this.

I purchased a 2015 Honda Civic ex with a cvt. I can reliably reproduce a problem with the continuously variable transmission (cvt) stutters or jerks when gradually accelerating at in-town speeds (e.g., 10-40 mph). It happens most often when going from a slow speed (e.g., 10-20 mph) and gradually accelerating. A rear end collusion could take place due to the hesitation of acceleration. I took it to the della Honda dealership in New York state, but Honda has not issued any technical service bulletins (tsb); so they were unable to repair the problem. In other words, the dealership service department was unable to determine the necessary action to troubleshoot or diagnosis the trouble without assistance from Honda. The dealership service department hooked up my car to the diagnostic tools and no service codes or out-of-spec messages appeared, so they said this is normal. There has been a lot of complaints about this particular trouble with the cvt, but Honda is resisting to acknowledge the trouble. I had to pay out of pocket for changing the transmission fluid with a brand new vehicle with only 4,864 miles on it and it appeared to resolve the trouble.
