Some 2017-2018 Mazda CX-5 and Mazda6 vehicles may exhibit excessive body vibration/unusual noises when idling or driving after parking in extremely cold temperatures. This may be caused by the No. 1 engine mount rubber hardening under extremely cold temperatures. To eliminate this concern, the material of the No. 1 engine mount rubber has been changed to increase damping force under extreme cold conditions.

Replace the No. 1 engine mount using the part numbers listed here.
