Service bulletin TI-106-1

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.

No. 72-172021-02-01. Service bulletin. Instructions for reworking the fan motor in the event that the HVAC does not function.
122-N8Y2M-062017-09-14. Service bulletin. Concerns: Vacuum lines for sound symposer Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is a possibility that the vacuum line on the change-over valve for the sound symposer can slip off on the affected vehicles due to relative movements of the engine. As a result, there is no guarantee that the sound symposer and other vacuum-controlled actuators on the engine will function correctly. This causes the warning message "Fault cooling system" to be displayed in the instrument cluster.
