I have a 2016 EX (sunroof and leather) with 100,00 miles. I had been having the shuddering issue for severaL months and had the transmission fluid changed around 80,000 miles per Honda. Ran ok a week or 2 then shuddering consistently got worse. Took to mechanic who had TSB - he changed my fuel injectors and took to have software update for transmission done. Ran great a week or so and now the shuddering on acceleration or around 50mph is driving me nuts! Financially I cannot trade for anything else right now or I would and just spent $1200 so I am tapped out on repair $. Anyone have this problem and have suggestions? some people are saying it could be the torque converter which I hope not.
