About 2 weeks ago started hearing what sounded like a earing going bearing from under the hood on driver side. I took it to the dealership yesterday, told them im pretty sure bearing going out on MGU. The dealership called me about hour and half later, the MGU and belts tensioners failed. They have no clue when parts will be in to fix under warr. I must be one of the lucky ones and caught the problem before major problems started.
