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.

122-D4S3S-012018-01-29. Service bulletin. ENGINE. Concern: On vehicles with a conventional drive system, the fuel that gets into the engine oil is evaporated by the high operating temperatures of the combustion engine. However, this fuelmight not evaporate fully due to the comparably low temperatures of the engine in hybrid mode on the affected vehicles. If the combustion engine does not reach a higher operating temperature for a long time, e.g. during frequent short trips, this can cause the oil level to increase to such an extent that the oil level measurement will activate the warning message "Oil level above maximum" in the instrument cluster. However, the functional properties of the engine oil are always guaranteed.
122-L4X2R-102017-11-08. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. There is a possibility that the function of the change-over valve for the sport exhaust system can fail as a result of water leaking in and causing corrosion. If this happens, the mode that was activated last will remain active. It will no longer be possible to switch between Sport and Normal mode in this case.In the event of a customer complaint or spare parts requirements for the change-over valve, the change-over valve and several individual components must be replaced - until such a time as the change-over valve becomes available as a repair kit,
122-J8S9J-112017-10-15. Service bulletin. ENGINE AND ENGINE COOLING. Customer complaint about loss of coolant, visible on the underside of the engine/where the vehicle was parked. Sometimes a yellow warning comes on in the instrument cluster with the information message? "Refill coolant Observe engine temperature". Component tolerances between the coolant pipe flange and distributor housing can cause leaks.
122-Y6G5Z-112017-10-15. Service bulletin. ENGINE. The unwarranted errormessages "Hybrid system fault" and "Reduced engine power" can appear sporadically in the instrument cluster on the affected vehicles under certain driving conditions because the diagnostic function for the hybrid decoupler is too sensitive. If this happens, engine power will be reduced and the Check Engine light will be activated until the ignition is switched off and on again.
122-Q5C4S-062017-07-28. Service bulletin. ENGINE; ELECTRICAL SYSTEM:WIRING. Issue: Oil in the wiring harness. Information: If oil is found in the engine wiring harness during a repair, the wiring harness and all the affected components (including the oil pump control valve) must be replaced.
