Which Mercedes-Benz model has oil leakage issues?

Mercedes-Benz oil leakage involves an imported Mercedes-Benz CLS300 sports sedan, equipped with an engine delivering maximum 258 horsepower and 370 Nm torque, paired with a 9-speed automatic transmission. Below are details about the Mercedes-Benz CLS300: Dimensions: The new CLS measures 4988mm in length, 1890mm in width, and 1404mm in height, with a wheelbase of 2939mm. Compared to the current model, its length and width have increased while the height has been reduced. Exterior Design: The rear contour lines of the new CLS are exceptionally clean, featuring LED-lit trapezoidal taillights with no additional design elements. Since the license plate mounting position has been relocated to the rear bumper, the space between the taillights is occupied solely by a large three-pointed star emblem.

After driving Mercedes-Benz cars for many years, I've found that oil leakage issues mainly occur in some older models, such as the ML350 and E350, particularly those manufactured between 2006 and 2010. These vehicles are equipped with M272 engines that have defective oil seal designs, which are prone to aging and deformation under high temperatures, leading to oil leaks. The problem isn't obvious at first, but after several years of driving, oil stains may appear beneath the engine, affecting performance and potentially causing safety hazards. Owners often complain about seeing oil droplets in parking spaces, necessitating timely oil seal replacements or professional inspections. Newer models like the GLB or GLC have improved sealing technology, significantly reducing the risk of oil leaks. Regular maintenance checks of the engine compartment can help detect issues early and avoid major repairs.

As a car owner, my Mercedes-Benz C-Class once had an oil leak due to a faulty crankshaft rear oil seal. I've heard that the E-Class and S-Class also suffer from this issue. Oil leaks typically occur after prolonged vehicle use, especially during the hot summer months. I found that the root cause is the oil seal material's lack of durability and insufficiently robust design. If you encounter this situation, promptly clean the oil stains to prevent environmental contamination and find a reliable repair shop to replace the parts. Regularly check the ground when parking; if you notice oil stains, don't delay—safety first. The newer Mercedes models like the EQ series have more rigorous sealing, but older vehicles require diligent maintenance.

Oil leaks are commonly found in older Mercedes models with V6 engines, such as the ML or GLE series, often due to deteriorated seals. Vehicles equipped with the M272 engine are prone to oil seepage as rubber gaskets loosen over time, especially after frequent high-speed driving. This design flaw frustrates owners, with reinforced seal replacement being the solution. Oil leaks can shorten engine lifespan, so regular checks of oil levels and engine condition are crucial to prevent minor issues from escalating. Opting for professional repair shops ensures quicker fixes.
