| 05-004-23 | 2023-09-03. Service bulletin. ENGINE AND ENGINE COOLING; POWER TRAIN. Some customers may complain about a surging at low speeds and during acceleration. This surging is in the longitudinal direction, felt about 2 cycles per second, and occurs in the locked up 1st gear. This may be caused by the torque fluctuation and the torsional resonance in the torque converter. To correct this concern, the PCM software has been modified to reduce the torque fluctuation. |
| SA-039-23 | 2023-08-05. 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-044-23 | 2023-08-05. Service bulletin. SUSPENSION. Some customers have reported experiencing a one-time popping or clunking sound while driving their vehicle. The noise is most noticeable when duplicating the driving conditions of going up or down an incline while simultaneously making a turn. NOTE: For Mazda6 vehicles, the noise may only be heard once per day. To reproduce the concern, allow the vehicle to sit overnight and then drive it. The noise has been traced to the front stabilizer (sway bar) bushings and the recommended action is the following repair information (if the noise can be duplicated). NOTE: The repair itself is not complex, but accurately replicating the concern may require additional time. To minimize inconvenience to the customer, ensure that they are provided with a loaner vehicle while the diagnosis and repair take place. |
| 09-028-23 | 2023-08-03. Service bulletin. EQUIPMENT:ELECTRICAL. Some CX-5 and CX-30 customers may find that the liftgate does not close when pressing the power liftgate (PLG) rear switch (A) located on the interior liftgate trim. This may be caused by PLG switch corrosion. Water from a high pressure car washer and/or condensation may drip onto the switch connector and cause corrosion. To eliminate this concern, the PLG rear switch has been modified with a waterproof connector. |

| SA-036-23 | 2023-07-05. 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. |
| SA-035-23 | 2023-07-05. Service bulletin. ENGINE AND ENGINE COOLING. Some customers may complain of a lack of power under heavy load without any warning lights or DTCs.
