I had been experiencing louder than what should be normal noise while driving my vehicle. Several days later the vehicle started to vibrate while in motion driving through city streets. Then on November 24th while driving along the NJ turnpike the vehicle began to vibrate and bounce so severely that I had to pull over because I thought a tire was going to blow out. The vibration was so intense while going the speed limited.I had to reduce the speed and drive with hazards on to get to my location. I immediately made a service appointment to have the vehicle looked at. The Volvo service department conducted a road test as well as a balance test. What I was told was that the foam belt inside 3 of the 4 tires had started to break free which caused my vehicle to vibrate all over the freeway. The dealership said that they would remove the foam and that they tires "should be ok" or they could replace the tires but I would have to pay for them. I have a brand new car that is leased with brand new Continental crosscontact LX sport tires and I believe that the manufacturer should be responsible for fixing the defect that occurred in the tires.honestly, I am lucky that my car didn't flip over!
