- Reliability (2)This generation is notorious for mechanical issues, specifically valve stem seal failures, coolant pipe leaks, and a myriad of expensive electronic sensor glitches.
- Maintenance (1)Maintenance is exceptionally costly; the car requires specialized diagnostic tools and high-priced OEM parts, making it one of the most expensive used cars to keep on the road.
- Technology (4)Highly advanced for 2006 with features like soft-close doors and active dampers, though the early iDrive system can be unintuitive and frustrating to use.
