So I'm nearly at my whits ends. I have a 2010 Journey with less than 20,000 miles. Since day 1 of owning it with no miles I have experienced a strange vibrations coming up thru the frame of the vehicle. Below 65 I dont feel it. Above 65 I start to feel it, and then above 70 it's more pronounced. I have had it checked 3 times at 3 different dealers. Have had the tire balancing checked nearly a half dozen times. They claim the tires are balanced. So where is this vibration coming from? I don't get it! Also, within the last couple months I notice this real high pitched nearly whistle like noise during acceleration. The pitch of the noice is consistent with the engine RPM's and with the shift points of the transmission. I have the 62TE 6 speed automatic. It has the all wheel drive. I cant' say that the vibration problem has gotten any worse since starting to hear this high pitch whining noice during acceleration. Anyone else have any suggestions? I'm seriously getting so pissed with Chrysler. I have a complaint in with Chrysler customer service and am awaiting a call back from a case advisor. Other than this funky vibration and now this more recent problem of the hight pitched whistle/whining noice I have really liked the vehicle. I've read on other forums that ther vibration could be coming from a turbulant issue due to the rear bumper design and catching too much wind causing a turbulant buffeting sensation. Ok so now what? ha! One other quick thing, when the temp falls below 30 over night and when I start the engine in the morning it knocks real bad for about 5 seconds before it goes away. Oil is clean, as I change it often. It's also full. Not low at all. Don't get this either. As far as the high pitched whine, I have read that there is a service bullitin issued for this very problem on the 62TE 6 speed automatic. I have had it in, and they claim they don't hear it. Well it's not a very loud pronounced sound, but if you really listen you can hear it if the window is down and you listen while accelerating. I'm ready to drive the thing off a cliff and collect the insurance money! HELP PLEASE! Any suggestions would be greatly appreciated!!!!! THANKS!!!!
