2-3 weeks ago i had a set of 4 tires put on the accord. Immediately after driving it i noticed a vibration at speeds of 55+. Two other people riding in the car with me on separate occasions also noticed the vibration. So about a week later i took the car back to where i had the tires mounted/balanced and explained the issue. 3 hours later i pick up the car and they tell me 1 front tire and 1 back tire was slightly out of balance but only slightly and that they had rebalanced them. On the drive home i notice the vibration is there there. This time slightly less. I ignored it thinking it was some sort of false issue i was creating in my head, but a week later the vibration is starting to drive me crazy. The ride just isn't as smooth as it was before. What ever is causing the vibration is also causing the "helicopter" effect in the cabin. Like where you have the windows open just enough it sounds like helicopter blades. Its not nearly as bad as having a window open, but its definitely noticeable.
So, What would CR do? Take the car back and tell them the vibration is still there? Or man up and get over it?
