What Problems Does the 2006 Mercedes-Benz S-Class Have?
The 2006 Mercedes-Benz S-Class, while a marvel of engineering for its time, is notorious for several frequently reported problems, primarily concerning its complex systems. The most prominent and costly issue is the Airmatic air suspension system (standard on most models) or the even more sophisticated and expensive Active Body Control (ABC) hydraulic suspension (found on S600 and AMG models). Components like air springs, struts, compressors, valve blocks, and hydraulic pumps are prone to failure, leading to a sagging ride height and requiring very expensive repairs, often in the thousands of dollars per corner or system component.
Electrical system malfunctions are also common. Owners frequently report issues with the COMAND infotainment system (display failures, navigation glitches), window regulators failing, instrument cluster pixel degradation, battery drain, various sensor failures (e.g., crank position sensor, O2 sensors), and general wiring harness deterioration. The complexity of the electronics makes diagnostics and repairs challenging and costly.
While generally robust, the 722.6 automatic transmission can develop issues over time, especially if fluid changes are neglected. Common problems include rough shifts, delayed engagement, or valve body failures. Engine issues, such as oil leaks from valve cover gaskets or oil cooler seals, are also reported on higher-mileage examples.
Regarding recalls, for the W220 S-Class, specific recalls included potential issues with the wiper motor (some models), certain fuel pump relays, and minor electrical components. However, for the 2006 model year specifically, there weren't widespread, catastrophic safety recalls that define its ownership experience; rather, the concerns are largely wear-and-tear related to its advanced systems. Long-term reliability is primarily hampered by the sheer cost of parts and the specialized labor required to diagnose and fix these sophisticated problems, making it a demanding vehicle to maintain beyond its warranty period.

High-end trims often featured a premium Harman Kardon Logic7 surround sound system. Other interior tech included multi-zone automatic climate control, heated and power-adjustable front seats, and a power rear sunshade.
For driver-assistance, it offered advanced features such as PARKTRONIC (front and rear parking sensors), rain-sensing wipers, automatic headlamps, and, notably, Distronic adaptive cruise control. This system could maintain a set distance from the vehicle ahead, a highly advanced feature for 2006. Keyless-Go, allowing keyless entry and ignition, was also available.
Safety was paramount, with a comprehensive suite of features. This included standard Anti-lock Braking System (ABS), Electronic Stability Program (ESP), and numerous airbags (front, side-impact, and window curtain airbags for head protection). Mercedes-Benz's pioneering PRE-SAFE system was standard, which could detect an impending collision and automatically pre-tension seatbelts, adjust front passenger seats, and close the sunroof and windows. The Tele Aid emergency call system provided automatic collision notification and roadside assistance.
Optional luxury features included ventilated and massaging front seats, a heated steering wheel, a rear seat package with heated and ventilated power-adjustable rear seats, and a panoramic sunroof. While the S-Class was engineered for exceptional occupant protection, specific crash-test ratings from modern agencies like NHTSA or IIHS for a 2006 model are generally not available. However, it was designed to meet and exceed the highest safety standards of its era, demonstrating robust structural integrity in real-world scenarios.
