Upon driving on the highway for the first time post rotation I started experiencing severe vibrations in my steering tire rotation at about 6k miles. Upon driving on the highway for the first time post rotation I started experiencing severe vibrations in my steering wheel and entire truck. I immediately brought it back to the service department and was told they did not re balance my tires upon rotation and I would need to schedule another appt. Considering the amount of vibration and potential for damage/risk, I took it to discount tire who told me the balance was not only off by .3 but that the lug nuts were not properly torqued causing 2 of the wheels to not be sitting flush on the hub. I had higher expectations of a dealership to #1 do the job correctly and #2 have a higher level of customer service to take care of a problem they created right away. More
