I have bought a brand new Dodge Ram 1500 2015 model. The car is shaking at low speed 80km/hr (50 mph) while the steering wheel is not shaking. I can feel the vibration in the seats, however the vibration stops at higher speed 100km/h (60 mph ) or higher. The dealer says that its a problem in balancing and he can change the tires also and re-balance.
Can it be any other problem?
Please advise as I know if its a tire problem it should increase while acceleration not fading?
