The wheelhouse liner may be coming into contact with the tire on some 2016-2018 Cruze models. If this condition is found, verify that all four underbody tire air deflectors are properly installed in front of the front tires (Fig. 16) and rear tires. (Fig. 17) The deflectors are a structural part of the wheelhouse liner and damage may occur if the vehicle is operated without the deflectors or if the deflectors are not installed correctly.
The four air deflectors are shipped with the vehicle for installation during the Pre-Delivery Inspection (PDI). One air deflector should installed in front of each tire. There are different air deflectors for the front tires and rear tires. Make sure the underbody is clean before installing the deflectors. (Fig. 18)
