Service bulletin MC330423

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

Since October 2023, a new maintenance schedule is valid for all K5x models. For the first time, maintenance positions for the cardan shaft (Driveshaft) are included. NOTICE: 1. The new maintenance schedule is not limited to vehicles affected by the SI 33 02 22 (SERVICE ACTION: Swingarm Drain retrofit and Driveshaft Check), but is valid for all K5x models - including retroactively. In case of retroactive validity (model year 2023 and older), affected customers will be informed about the change. This will be in the form of a direct-to-customer letter with a description of the new maintenance schedule, specific owner’s manual insert, and consumer warranty book insert. 1. For vehicles affected by SI 33 02 22 (SERVICE ACTION: Swingarm Drain retrofit and Driveshaft Check), this service action must be performed first. All conditions described in this bulletin apply after the open Service Action has been completed. No additional communication is required for K5x models model year 2024 and onwards. Those models have the new maintenance schedule in their owner’s manual.

Listing a model year does not mean every vehicle of it is concerned: the document says which.

A recall listed here may apply to some of the same vehicles. Only the manufacturer can say whether it applies to one vehicle.
