Service bulletin 09-011-20-3644

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 exhibit power outer mirror(s) that do not fold in and/or out when using the outer mirror switch. This concern may be caused by insufficient water tightness, allowing water to enter the electric folding unit resulting in corrosion damage. To eliminate this concern, the overlapping area (1) of the water-proof seal (inside electric fold-in unit) has been extended.

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.
SA-012-232023-04-04. Service bulletin. Some customers may report an odor or water in the HVAC system and upon inspection, the cabin air filter may be found to be wet.
SA-010-232023-03-03. Service bulletin. Some customers may experience one or more electrical malfunctions after a vehicle body repair. The newly painted fender stay (2) may be causing a poor front harness (1) ground connection.
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.
SA-074-222022-12-02. Service bulletin. Some customers may complain the HVAC system not maintaining the correct temperature or the ambient (outside) temperature reading incorrectly. This is caused by a failure in the ambient temperature sensor. To correct this issue, the ambient temperature sensor has been modified.
07-004-21-38302021-10-31. Service bulletin. Some vehicles may exhibit insufficient A/C performance / insufficient airflow from vents or ducts. These concerns may be caused by an evaporator temperature sensor malfunction due to insufficient water-proofing. This may result in a detection error and therefore, improper operation of the A/C system. To eliminate this concern, the production process of the evaporator temperature sensor has been modified to ensure proper water-proofing.
15-003-21-38282021-10-02. Service bulletin. Some vehicles equipped with Blind Spot Monitoring (BSM) may experience a BSM indicator light on the outer door mirror, even if there is no vehicle in the alert (blind spot) area. NOTE: This concern occurs only after a cold start. As the BSM control module temperature rises, the BSM system returns to normal operation. Due to BSM control module production variances, a false detection may occur in some units when the BSM temperature in the control module has not yet reached normal operating temperature. To eliminate this concern, the control logic of the BSM control module has been modified.
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.
MT-003-212021-06-29. Service bulletin. 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.
SA-022-212021-04-06. Service bulletin. When performing the MGSS Workshop Manual 360° View Monitor System Aiming Procedure, M-MDS may show error message "Procedure unsuccessful". This may be caused by light glare on the SST.
