“On December 4, 2021, I was accelerating to get on the freeway when my Bronco started shaking (from the front of the vehicle/under the hood) and refused to speed up. I was thankfully able to pull safely off the freeway into a vacant lot and wait for a tow. The work was completed, but I still had to wait over a month before getting my vehicle back. The entire engine needed to be replaced.”
