I have had my 2009 Dodge Journey in the shop now 3 times and am bringing it in today for the FOURTH time for the SAME problem!! It seems to only happen when I hit 60mph and higher. My whole car shakes, I can feel the vibrations in my seat, in the gas pedal... everywhere. As soon as I take my foot of the gas the shaking stops, but as soon as I put it on again it starts again. I find sometimes if i step on the gas it will resolve itself but other times not so much. The check engine light comes on but everytime i take it into the dealer it does not register the light ever going off. I am at my WHITS end!!! The replaced something in the fuel injector vlaves and exhaust valves with no help. The last time the balanced my tires to take care of the problem. Yea, that didnt help!! Any light to shed on this subject will be VERY helpful!!!
