Summary Verdict

The 2006 Mercedes-Benz Multego, built on a foundation of commercial vehicle engineering, generally offers good reliability. The powertrain, particularly the diesel engines, is robust but can be susceptible to issues like injector seal leaks and turbocharger problems, especially with higher mileage. Transmission issues, particularly with the automatic, can arise, often related to the control module or torque converter. Suspension components, especially air springs, require attention due to potential leaks. Electrical gremlins, often stemming from the BCM, are not uncommon. Exterior corrosion can be a concern in certain climates. Interior issues are typically minor, such as HVAC blower motor problems. Overall, while not immune to faults, the Multego’s core mechanicals are durable, but owners should be prepared for potential maintenance costs associated with its premium components and commercial-grade construction.
