09-014-23a2023-08-03. Service bulletin. STRUCTURE; VISIBILITY:REARVIEW MIRRORS/DEVICES. Some vehicles may experience white-streak stains appearing on the front door that look like they seeped out from under the outer mirror base. This is caused by water intruding from gaps of the outer mirror body and/or the hinge of the outer mirror, and corrosion occurring on the aluminum die-cast inner base in the outer mirror. Water, including white-salty corrosion, may drip out from gaps under the outer mirror base resulting in white stains on the front door. To eliminate this concern, the front outer mirror inner base has been modified.
SA-036-232023-07-05. Service bulletin. STRUCTURE; EQUIPMENT. Interior parts made of resin have antistatic coating to prevent dust from sticking on the surfaces, and depending on the conditions of use, the antistatic components may crystallize slightly, giving an appearance of white stains on the surface. To remove the stains, wipe the stained surface with a towel soaked with water mixed with a small portion of a neutral detergent. If the white stains reappear again, simply wipe them again in the same way. NOTE: The antistatic effect does not deteriorate with this procedure.

Some customers may report hearing an unusual noise coming from the power liftgate (PLG) when it is unlatching to open or latching closed. This is caused by an internal fault in the liftgate latch and/or loose bolts holding the latch to the liftgate. To eliminate this concern, the internal structure of the latch and surface treatment of the bolts have been modified.

SA-008-22a2022-11-04. Service bulletin. STRUCTURE. Some vehicles may experience exterior trim heat damage when parked near a glass building or Low-E windows. This may be caused by the sun's reflection.
SA-059-222022-09-06. Service bulletin. STRUCTURE. Some customers will report that their fuel door was stuck closed and would not open to refuel the vehicle. Follow the repair steps below unless the conditions outlined in TSB 09-019/21 - FUEL-FILLER LID PANEL IS DEFORMED are present.
09-015-222022-05-05. Service bulletin. STRUCTURE:BODY:HATCHBACK/LIFTGATE; LATCHES/LOCKS/LINKAGES. Some vehicles may exhibit corrosion on the liftgate lock striker. This may be caused by water penetrating from micro cracks existing on the lock striker's coating surface that reacts with zinc contained in the undercoating and produces the corrosion. To eliminate this concern, a modified undercoating has been established for the liftgate lock striker.
09-008/222022-04-05. Service bulletin. EQUIPMENT; STRUCTURE. Some vehicles may exhibit water leaking into the passenger compartment from the rear door through the bottom of the service hole behind the rear door trim during rain or when washing the vehicle. This is caused by one of the following: *Since the material of the seal rubber is not resistant to surfactants, the rubber deteriorates when the vehicle is washed and allows water to penetrate into the seal rubber of the service hole cover. *The lower tabs of the service hole cover may not have been completely engaged at the factory. To eliminate this concern, the seal material of the service-hole cover has been changed (Japan built Mazda3) and a mass production change will be implemented in the future (Mexico built Mazda3 and CX-30).
SA-008-222022-03-04. Service bulletin. STRUCTURE. Some vehicles may experience exterior trim heat damage when parked near a glass building or Low-E windows. This may be caused by the sun's reflection.
MT-001-222022-03-04. Service bulletin. UNKNOWN OR OTHER; STRUCTURE. Some customers may report concerns with interior upholstery surface stains particularly on high contact areas (e.g.: steering wheel, door panels, shifter...etc.). This may be caused by skin oils or chemicals such as hand lotions. Use a clean towel damped in leather/vinyl cleaner or mild soap to clean the steering wheel. NOTE: Upholstery maintenance and care information can also be found in the Owner's Manual.
09-039-21-38072022-01-06. Service bulletin. STRUCTURE; EQUIPMENT; ELECTRICAL SYSTEM. Door Outer Handle Touch Sensor Does Not Lock And/Or Unlock: Some customers may experience one or both of the following symptoms while locking and unlocking the doors works fine using the remote transmitter. Symptom 1: The touch sensor of the front door outer handle does not lock the doors after rain and/or car washing, even though unlocking is possible. Symptom 2: The touch sensor of the front door outer handle does not unlock the doors. Cause 1 (for Symptom 1): Water may accumulate around the touch sensor in the outer handle, resulting in temporary lower sensitivity of the capacitive sensor. Also, if car wash foam gets inside the outer handle while washing the vehicle, the foam may disturb the touch sensor detection. Mazda is still working on a mass production change for this concern. Cause 2 (for Symptom 2): Improper soldering in the production process may disturb the touch sensor detection. To eliminate this concern, the production process has been modified. Customers having this concern should have their vehicle repaired using the following repair procedure.
09-038-21-38552022-01-06. Service bulletin. STRUCTURE. Rear Outer Door Handle Fails To Return Due To Water Freezing In The Handle: Some vehicles may exhibit the rear outer handle remains pulled out and does not return when the rear outer handle is operated in freezing temperatures. This is caused by the accumulation of snow on the rear outer handle melting and dripping water on the sliding part of the lever. When the water freezes due to decreased temperature and the handle is operated, peeled ice gets caught between the outer handle case and the slide, causing the return failure. To eliminate this concern, the shape of the rear outer handle has been changed to prevent the accumulation of water on the sliding part of the lever. Customers having this concern should have their vehicle repaired using the following repair procedure.
09-019-21-3813a2022-01-06. Service bulletin. FUEL/PROPULSION SYSTEM; STRUCTURE; EQUIPMENT. Fuel Filler Lid Panel Is Deformed: Some vehicles may exhibit a deformed fuel-filler lid panel (1) attached to the fuel-filler lid box, resulting in a poor appearance. This concern is caused by the lid box not having enough water drainage capability which leads to the accumulation of water inside it. The water then freezes in cold weather and expands or the inner side of the lid panel absorbs the water and swells from long exposure, deforming the lid panel. To eliminate this concern, the shape of the fuel-filler lid box has been modified to have better drainage capability and a modified fuel-filler lid panel service part has been established for less water absorbance. Customers having this concern should have their vehicle repaired using the following repair procedure.
SA-035-21a2021-10-05. Service bulletin. STRUCTURE. A customers may experience a roof water leak. The symptoms may include: Water in the spare tire well, Water in the rear differential, Electrical malfunctions, Infotainment system no audio sound from radio or other audio sources due to Remote Tuner water intrusion.
