It seems like I am having the same problem as everyone else on here. 2010 Journey with 12,000 miles. Engine shudder happens only when car is cold and starts about 2 miles from my house from about 50-60 miles per hour. Whole car shakes and I have to let off accelerator, Shudder starts again when I get back on the gas pedal. I took into dealer a week ago, of course no codes stored in computer. Same thing happened today this time check engine light stayed on for about a minute. Took it to dealer and they said bring back in morning. My problem is I know they are not going to find anything(unless a code was stored in computer this time). I am going to print this post and take to them when I drop car off. Anybody have any other suggestions what i can do to get this problem solved without having to go to dealership numerous times?
