2024-01-03. 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. NHTSA's copy of the document (PDF)
2018-11-13. N63 Engine: Check the Timing Chain. INFORMATION This bulletin outlines the procedure to check the engine timing chains for wear and should be completed in conjunction with SI B11 06 14 "N63 Customer Care Package". Performing the test plans identified in the procedure below will detect wear at an early stage and if necessary provide a repair solution. To avoid future valvetrain wear, the vehicle must be reprogrammed and a shorter oil service interval must be retrofitted via ISTA/P. Finally, drain and replace the engine's oil and filter. After completing all necessary repairs included in the N63 Customer Care Package and the Timing Chain Check, the vehicle must be test driven for up to 30 minutes to assure the highest standard of performed repairs.

The N63CCP and N63 Engine Check the Timing Chain are NOT mandatory Technical Campaigns or Recalls. They should be completed only based on parts availability, workshop capacity, and the customer's schedule. Performing the test plans identified in the procedure below will detect wear at an early stage and, if necessary, provide a repair solution. To avoid future valvetrain wear, the vehicle must be reprogrammed and a shorter oil service interval must be retrofitted via ISTA/P. Finally, drain and replace the engine's oil and filter. After completing all necessary repairs included in the N63 Customer Care Package and the Timing Chain Check, the vehicle must be test driven for up to 30 minutes to ensure that the repairs were performed to the highest standard. AFFECTED VEHICLES This Service Action applies to E70, E71, E72, F01, F02, F04, F07, F10, F12, and F13 vehicles with the N63 engines corresponding to the production dates listed above. First check if a Service Action label with a code number 728 is already attached to the B-pillar. If a code number 728 has already been punched out, the Campaign has already been performed and no further action is necessary. Eligible vehicles will show the following Service Action-related Campaign Code: 00 13 48 02 00 If the vehicle already has a label from a previous Service Action/Recall Campaign, affix the new label next to the old one. Do not affix one label on top of another one, because a number from an underlying label could appear in the punched-out hole of the new label." NHTSA's copy of the document (PDF)

Bulletins from the manufacturer that mention a maintenance schedule or a service interval, as NHTSA summarises them. They are not the schedule itself: read the document, and the owner's manual.
Position 8 of a VIN names the engine on many vehicles: how to read a VIN. Safety equipment depends on the trim, so decode a VIN to see what one vehicle has.

These are counts of the complaints owners filed with NHTSA about this model year. A complaint is an owner's report: it is not verified by NHTSA or by this site, and it is not a finding that anything is wrong with the vehicle. A count is not a rate: a model that sold more has more complaints. A complaint may name several components, so the components do not add up to the total.
