Official summary
An issue has been identified on certain vehicles within the listed Affected Vehicle Range where depending on the type and style of driving that the vehicle is subjected to, the 'Service Required' message may be displayed on the Instrument Cluster (IC) at a distance less than that shown in the service interval plans. The software update within the Diagnostic Procedures will separate the oil dilution counter from the time and distance service counter, allowing individual counter resets to be applied depending on the type of service completed.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
