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.

SSPC7a	2021-10-02. Service bulletin. SSPC7 - SPECIAL SERVICE PROGRAM -TELEMATICS COMMUNICATION UNIT BATTERY DRAIN CONCERN AND CONNECTED SERVICES NOT AVAILABLE: Repair Outline and Important Notes: Reprogram the telematics communications unit with an USB stick. You must use MDARS after USB programming to check for DTC and sending ODR data. New information has been added to SSPC7 repair documents. Discard all other documents and print these documents out. DRW41 repaired vehicles will not need SSPC7 completed. Unrepaired DRW41 vehicles have been moved to SSPC7. You must check DRW41 status prior to repair in Warranty Vehicle Inquiry. Open status, perform SSPC7. Closed status, return vehicle to stock or customer after confirming CV signal strength. Unsubmitted DRW41 claims with repair dates of August 2 or later must be submitted with SSPC7 claim information. Warranty Operations will be deleting DRW41 VINs in open status over the next few days. SSPC7 must be performed prior to delivery and is subject to the New Car Ready process
SA-070-17	2021-03-08. Service bulletin. If you receive a customer complaint of an engine oil warning light illuminating, with DTC P250A:00 stored in the PCM, it may be caused by overfilling the engine oil.
07-007-16	2021-02-01. Service bulletin. Air intake mode does not work after repair of rain sensor, FBCM, IC, PCM, or TCM. After performing any one of the following repairs, the air intake link at the blower unit may disengage and result in the HVAC systemnot switching between recirculation and fresh air modes. * Replacing rain sensor * Replacing front body control module (FBCM) * Replacing instrument cluster (IC) * Reprogramming any control unit (PCM, TCM, etc) - manual A/C only. This is caused by the air intake link in the blower unit not being sturdy enough for the actuator torque under fail safe fmode. Fail safe mode occurs when a communication error occurs between the A/C control unit and the humidity sensor. To c orrect this problem, the blower unit has been modified.
05-010-16	2021-02-01. Service bulletin. Shift shock while accelerating from A stop. Some customers may complain about a slight shift shock while accelerating from a stop and no A/T related DTC's are stored. The shift shock actually occurs intermittently at lock-up transition with the A/C on. Improperly learned values in the TCM for the lock-up slip control may cause excessive pressure for the lock-up clutch. To avoid improper learning, the control logic of the TCM has been changed. Customers having this concern should have their vehicle repaired using the following repair procedure.
05-002-20-3704b	2021-01-05. Service bulletin. 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.
01-011-19-3586a	2019-08-01. Service bulletin. Some customers may experience a check engine light illuminating with DTC P2096:00 stored in PCM memory. DTC P2096:00 - Air fuel too lean. NOTE: This concern occurs only on vehicles with PCMs manufactured by MITSUBISHI. Due to improper control logic of the PCM, a false error may be detected. To eliminate this concern, the PCM software has been modified.
01-008-19-3568a	2019-04-25. Service bulletin. Some customer using “Flexible” setting for Oil Change in the maintenance monitor may notice that the oil change due notification will not work due to improper control logic of the PCM. The PCM clears the TRAVELED DISTANCE at the wrong time while the ELAPSED DAYS and the DETERIORATION DETERMINATION work as designed. To correct this issue, the control logic of the PCM has been changed.
