If you receive customer reports in the above model vehicles of the oil level warning message frequently appearing in the instrument cluster, "Oil level
too low" or "Check Engine Oil Level at Next Service Stop", but the oil level is correct on the dipstick, there could be several causes depending on the
vehicle. This document is a consolidation of those possible causes.
