2018 Mazda CX-3 Technical Service Bulletins

477 technical service bulletins (TSBs) are on record for the 2018 Mazda CX-3. TSBs are notes manufacturers send to dealers about repair procedures for issues seen in the field. They are not recalls and do not by themselves mean a vehicle has a fault.

• 10237199May 17, 2023Transmission and drivetrain. Some vehicles may experience the check engine light and automatic transaxle warning light ON with one or more of these DTCs stored in the TCM memory (P0842, P0847, P0872, P0877, P0780, P1738).

If the Mazda DCA-8000 is not used, incorrect battery testing may result in unnecessary battery replacement. Use the following test procedures in this Service Bulletin to test Mazda vehicle batteries and to generate a Warranty Code.
• 10237200May 3, 2023Steering. Some vehicles may exhibit a light resistance and/or an unusual noise when turning the steering wheel in either direction. This concern may be caused by insufficient lubrication between the worm wheel gear and worm shaft. To eliminate this concern, the production process for the steering shaft has been modified.
• 10235414Apr 3, 2023Steering. Some vehicles may exhibit wear/peel-off of the leather steering wheel surface causing a poor appearance. This concern may be caused by an insufficient wear resistance of the steering wheel surface.
