Recently purchased a Sedona LX and am having one problem. At freeway speeds (60 - 75 mph) it has some vibration which feels to me like it is coming from the drivers side rear of the vehicle. If I adjust the speed I can make it better or worse. I have had the vehicle into the dealer twice for this problem and both times they balanced all the tires. The service rep now assures me that all the tires are in "perfect" balance. He also said they test drove it and it is OK. The balancing improved the vibration some, but is still not to my satisfaction. I drove my daughter's '06 Sedona EX on the same stretch of freeway and it is very smooth compared to mine. I know it has different wheels and tires, but shouldn't make that big of difference? Has anybody else had this experience ?
