Just bougth 2012 Journey SXT 3.6. So far I like it but one thing annoys me a lot - vibrations on idle - either when on park or drive - I have only 1600kms on it. The funny thing is that those vibrations are very random - some times I can drive all day and everything is super smooth, next day I'm sitting in traffic and everything is shaking - even passenger can feel it.. Had Mitsu Endeavor before with 190000kms and almost no vibrations at all. I heard that this can be cured by some engine software upgrade and it is a common thing with 3.6 Pentastar. Any thoughts? BTW as for mileage computer shows 14L/100km (I'm driving 99% in the city) - did couple of trips using highway and it showed 11L/100km - I'm guessing it's pretty much normal. Thanks!
