Official summary
Some vehicles may experience a rough idle with the mil on and dtc p0015 / p0524 stored in memory. P0015:00 - exhaust cmp timing over-retarded p0524:00 - engine oil pressure too low this is caused by a drop in engine oil pressure due to a piece of foreign object stuck on the oil pump pressure relief valve or ocv. The temporary entry of the foreign object triggers a mil illumination, but rough idle will not be produced until a later time.

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.
