Reliability snapshot
The E65 7 Series introduced iDrive and a wave of new technology, and its main ownership theme is electronic complexity — early iDrive, comfort-system, and control-module faults are the most discussed items. Mechanically, the N62 V8 has its documented valve-stem-seal and coolant-transfer-pipe wear, and cars with air suspension may need it refreshed. Well-maintained E65s are capable flagships, but electronics and V8 upkeep should be budgeted for.
