Service bulletin MT-003-21

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some vehicles may experience exterior trim heat damage when parked near a glass building. This may be caused by the suns reflection. If a building creates enough of a curve with a series of flat windows, which act like mirrors, the reflections all converge at one point, focusing and concentrating the light onto the street below.

Other bulletins for the same vehicles and component
SA-059-232023-11-01. Service bulletin. When the power windows are operated many times without being fully closed, small errors of the window position sensor may accumulate and cause improper operation of the jam-safe function. To reduce the risk of this occurrence, the AUTO function is disabled if the power window is operated 10 consecutive times without being fully closed (turning the ignition OFF and then ON does not reset the counting). If the power window is fully closed before the 10th time, the counting restarts and the AUTO function is not deactivated.
SA-039-23a2023-10-05. Service bulletin. 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.
09-011-232023-03-03. Service bulletin. Some vehicles may exhibit power outer mirror(s) that do not completely fold in and/or out. NOTE: This concern is unrelated to frozen mirrors in icy weather where snow or ice need to be removed for the mirrors to fold in and/or out. This concern may be caused by the following: The space between the mirror frame and the inner base may be too tight to allow for proper movement. Due to insufficient water tightness, water enters the electric fold-in unit and results in corrosion damage. The friction around the folding mechanism shaft may become increased.
09-010-232023-03-03. Service bulletin. Some vehicles may exhibit a condition where the power outer mirror will not fold in and/or out when the outer mirror holding switch (1) is operated. This may be caused by: 1. The electric fold-in unit inside the outer mirror may be damaged by corrosion from water entry due to insufficient water tightness. 2. The electric fold-in unit may interfere with the outer mirror frame due to improper installation of the electric fold-in unit. 3. The friction around the shaft of the folding mechanism may increase.
SA-040-212021-07-01. Service bulletin. 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.
09-045-18-35302019-02-19. Service bulletin. Some vehicles may exhibit the power window(s) not working properly (window does not move or has fallen into the door) and/or making an abnormal noise while operating the power window switch. This may be caused by the cable of the power window motor being damaged from water entry through area (1) of the front beltline molding.To eliminate this concern, the shape of the door glass will be modified during mass production to prevent water entry to the power window regulator.
09-036-18-35262018-10-09. Service bulletin. Some vehicles may experience one or more of the following symptoms in connection with a malfunction related to the C-15 connector. The driver side power window does not operate. The door does not open when using the advanced keyless system. The warning lamp stays ON even after the ignition switch is turned OFF. DTC B10E7:17 (START STOP UNIT, IG1 Relay Circuit Malfunction) and DTCs related to communication errors may be stored in PCM memory. Engine no start due to battery discharge. The symptoms listed above may be caused by corrosion of the C-15 connector terminals due to water intrusion through the front door. In low ambient temperatures, the door harness hardens. If the door is fully opened, it may create a gap between the door and the door harness grommet, which may allow water to enter through the gap.
09-032-17-33722017-10-21. Service bulletin. Some vehicles may experience one or more of the following conditions with the driver and/or passenger side power window(s): ? The window glass will not raise/lower. The window suddenly stops operating while being raised/lowered. The window glass gets stuck where it stopped operating or falls down in the door. This concern is caused by the window regulator cable end becoming disconnected from the fixing point due to improper caulking. The production facility has been improved to prevent the improper caulking of the window regulator cable.
SSPB02017-10-12. Service bulletin. Special Service Program (SSP) B0 2014 Mazda3 Front Power Window Regulator Cable. Dear Mazda Owner: Mazda Motor Corporation has decided to conduct a Special Service Program (SSP) on certain 2014 Mazda3 vehicles built From April 25, 2014 through June 14, 2014. If you are a recipient of this notice, your vehicle is included in Special Service Program (SSP) B0.On affected vehicles, the inner end of the front power window regulator cable may be improperly assembled at the production stage. Because of this, it is possible that the front power window regulator cable may be torn when lowering and raising the power window, which may prevent the proper operation of the window regulator.
