2011 Volkswagen CC VR6 ProblemsClunking Noise from Floorboard Under Acceleration
Drivers of the Volkswagen CC VR6 may experience a clunking noise associated with acceleration from a stop, or downshifting for hard acceleration. This will also be accompanied by a light impact sensation under the drivers feet. Drivers may also notice unexplained changes to their front end alignment while driving.
This issue is commonly called " VW Subframe Clunk", and is caused by the gradual stretching of the bolts that secure the subframe to the vehicle. The subframe is a large plate that secures to the bottom of the engine bay, and connects the body of the car to the engine and suspension. Over time, the bolts that secure the subframe stretch, allowing the subframe to move and hit the bottom of the car when accelerating.
There are many aftermarket kits that can be installed to correct the issue, and Volkswagen has issued a correction including better bolts, and spacers which fit between the subframe and the car.
