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-Y9K4F-092018-11-19. Service bulletin. WHEELS. Symptom: During and after race track use, loud noises can sometimes come from the wheel assembly on the rear axle - particularly on bends. Cause: Particles of dirt on the contact surfaces can cause micro-movements in the wheel assembly on the rear axle (rim/brake disc/wheel hub) and this can result in loud noises. Remedial Action: In the event of a customer complaint, clean the wheel assembly on the rear axle as described under "Work Procedure".
122-W6M7A-062017-09-14. Service bulletin. STRUCTURE:BODY; WHEELS. Concerns: Front wheel housing liner (front part) Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. When reversing out of the bed of gravel with hot tires during race track driving, small stones that are sticking to the front tires can become loose. These stones are flung against the radiators through an opening in the front part of the wheel housing liners and can damage the radiators.
122-K8Q9H-062017-09-14. Service bulletin. TIRES; WHEELS. Concerns: 20-inch Sport Classic wheel (I-no. XRU) Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. The opening for the wheel hub cover on the 20-inch Sport Classic wheel (I-no. XRU) was not machined correctly due to an error during the production process. As a result, there is no guarantee that the wheel can be balanced correctly when changing the tire, depending on the wheel balancing machine used. This can result in noticeable vibrations and reduced driving comfort.
