I have a 14 Silverado 4x4 1500 w/20" wheels. Vibration feels the worst at 65 till 72mph.
I have complained about it since new. They have balanced and rotated at every service. They have road force balanced also.
at 21,000 they replaced 3 of the tires. Same issue took back they replaced 2 of the 3 they had just put on. Before they called me they replace one of the 2 they just put on.???? maybe it's not the tires.
They ran it with a Peeko meter? I was told it's within specs. I call Bulls t! They had me come in after I told them that the 2, 16 models that they loaned me were not like mine.
They took the 18" tires and wheels off the loaner and put them on mine. I drove it with the tech. It was still there. Maybe not as bad but didn't come in till 80-85mph on the dash. They told me they would not do anything else to it. that speed is above any posted speed limit therefore GM was out!. I tried to explain that smaller wheel and smaller tire caused speedo calibration to be off, therefore to duplicate the same condition it would show faster than it was going. They argued that and said that they would not do anything else to it. What can I do? I suggested a different brand tire, driveshaft or shocks. I have seen posts on here from Jennifer at GM. who do I call.
I bought and have had it serviced at Jim Trenary Chevrolet in OFallon, MO.
It should be better with a $50,000.00 price tag
Thanks
