Purchased vehicle used @ 32k miles. vehicle almost un-rideable due to rough ride & terrible vibration. took to gmc dealer, they replaced one front shock (completely leaked out) and one bad rim. truck still rides extremely rough & has a vibration between 35-55 mph. almost unbearable on longer rides. tires are brand new. dealer says that it is within spec. this should be illegal on a $75k msrp "luxury" suv!
Vehicle shakes and vibrates horribly at hwy speeds i have taken it to the dealership with no fix same problem
When the vehicle reaches 40-60 miles per hour a vibration occurs... often sounds like a window is down and can cause nausea and headache...
