Introduction
Some 2014 – 2017 model year Highlander and Highlander HV vehicles may exhibit an abnormal
squeak, squawk or groan type noise from the rear suspension when traveling over uneven roads,
or when the vehicle comes to a complete stop, which may become more pronounced in colder
ambient temperatures. The abnormal noise may be caused by the rear trailing arm bushing. An
updated Rear Trailing Arm Assembly is available. Follow the Repair Procedure in this bulletin to

assisting to identify the source of the noise.
