MAN Truck & Bus Issues Recall for Euro 6c Engines Over Potential Fire Risk

(IN BRIEF) MAN Truck & Bus is recalling certain trucks and buses with Euro 6c engines (D2676LF51-53 and D2676LOH35-37) for inspection due to potential engine damage and fire risks. The recall affects vehicles manufactured between November 2016 and August 2019. MAN stresses the importance of adhering to maintenance schedules to prevent issues and has already serviced 50% of the affected vehicles. The company urges remaining owners to have their vehicles checked at authorized workshops.

(PRESS RELEASE) MUNICH, 29-Jun-2024 — /EuropaWire/ — Commercial vehicle manufacturer MAN Truck & Bus is urging customers with trucks and buses equipped with specific Euro 6c engines (types D2676LF51-53 or D2676LOH35-37) to have their vehicles checked at an authorized MAN workshop. This service requirement does not affect later Euro 6d and Euro 6e engine variants.

The recall stems from the rare possibility of engine damage and subsequent fires in vehicles manufactured between November 2016 and August 2019. These engines use lead-free bearings due to new regulatory requirements, which can be more susceptible to damage under certain conditions such as excessive aging and contamination of engine oil. This damage can occur particularly when maintenance schedules are not followed or are improperly performed.

Other factors contributing to potential engine damage include special operating conditions, engine overspeeding, water contamination in engine oil, engine tuning, use of non-approved engine oils, and non-compliant service parts like oil filters, air filters, and diesel filters.

Adhering to maintenance schedules is crucial, as failure to do so can result in engine damage typically appearing in vehicles with mileage between 400,000 and 500,000 kilometers. Conversely, MAN has observed that engines with timely and proper maintenance demonstrate high robustness, often exceeding a million kilometers without significant issues. Therefore, maintaining prescribed service intervals is vital for vehicle reliability and safety.

Since the end of 2022, MAN has informed affected customers multiple times, urging them to take preventive measures. Over 60,000 service actions have been completed in MAN-approved workshops, covering about 50% of the affected vehicles. Workshops have been instructed on the importance of oil quality and other technical measures, such as the precautionary replacement of potentially damaged oil filter covers and adjustment of oil change intervals for vehicles with demanding usage profiles.

With a fleet of approximately 880,000 vehicles in Europe, around 120,000 trucks and over 5,000 buses built between 2016 and 2019 are affected by this recall. MAN has documented 170 fire cases since these engines were introduced, with 18 cases occurring in 2024 potentially linked to the described damage pattern. Fortunately, these incidents resulted in property damage only, with no serious injuries reported.

As a preventive measure, MAN is once again calling on vehicle owners who have not yet utilized the service offer to do so promptly. MAN emphasizes that fires can have multiple causes and each incident must be individually investigated. The company remains committed to closely monitoring engine performance and collaborating with customers to ensure safety and reliability.
