Summary Verdict
The 2006 BMW 530i (E60) presents a mixed reliability profile. While the core powertrain components, particularly the 3.0L N52 engine and its associated transmissions, are generally robust with proper maintenance, owners should be prepared for potential issues in the electrical system, notably with the iDrive and ABS modules. Suspension components like control arm bushings and strut mounts are also common wear items. Interior issues such as clogged sunroof drains and HVAC blower motor failures can also arise. Despite these potential drawbacks, the 530i remains a desirable car for its driving dynamics, but thorough pre-purchase inspections and a budget for maintenance are highly recommended.
