Hi, I believe there have been numerous complaints on this forum for this topic, but I have a 2009 Dodge Journey with 50556KM on it. I have experienced violent shuddering at random times, usually when accelorating between 90 -100km/h.
I have had the engine light come on and disappear, then on this past Sunday the engine light came on and and did not go away. I brought it to the dealer and they said it had a code that meant the #2 piston misfired. They checked the plugs/lines piston compression, and a few other things I can't remember, but they could not make it happen again, and sent me on my mary way.
Last night the engine was shuddering again, very violently (no engine light though). I brought it back in today, and they mentioned a possible sensor malfunction (just a guess on their part at this time).
So far they seem very reluctant to try and dig any further or suggest a root cause to the problem. I am getting very frustrated, as this car only has 55000km, and alreadi I have had to replace all rotars and pads, an inner tie rod, a software update for the transmission shifting hard, and had to replace the radiator.
