Considering a used 2018 Mercedes-Benz GLE 350 and wondering about its reliability? Potential buyers often compare this model to previous Mercedes ML-Class vehicles, seeking reassurance about its dependability. Drawing from real owner experiences and expert perspectives, we delve into the reliability aspects of the 2018 GLE 350 to provide a comprehensive overview for those considering this SUV.
While Mercedes-Benz, as a brand, may sometimes face scrutiny regarding overall reliability ratings, the W166 GLE platform, particularly the gasoline V6 GLE 350, stands out as demonstrating better than average reliability within the Mercedes lineup. Owners generally report a satisfactory ownership experience, especially when adhering to the recommended maintenance schedule. Consistent and timely servicing is key to mitigating potential issues and ensuring the longevity of your GLE 350.
One area that has surfaced in owner discussions is the occurrence of engine oil leaks in the 3.5L naturally aspirated V6 (M276) engine. These leaks have been noted in some cases at relatively low mileage, sometimes even before the 40,000-mile mark. Common leak locations include the front cylinder head cover near the camshaft magnets/servos and the rear main crankshaft seal. While dealerships may sometimes initially dismiss these as “normal,” persistence can lead to repairs, particularly for more accessible leaks like those at the cylinder head cover. The rear main seal leaks, when they occur, are often characterized as slow weeps or sweating, which may be less critical but worth monitoring.
Beyond engine oil leaks, the 2018 GLE 350 generally holds up well in other critical areas. Transmission and brake performance are considered to be within the average range for vehicles in this class. Components such as axles, the base steel coil suspension, and steering systems are typically robust and reliable. Interior elements including seats, carpets, HVAC systems, and the Harman Kardon stereo (if equipped) also receive positive feedback for their durability and quality.
Fuel economy, at around 20 mpg combined, is acknowledged as being on the lower side for modern vehicles. However, the GLE 350 excels in utility, offering ample space and practical functionality. Its towing capability and roof rack compatibility make it a solid choice for those with active lifestyles. The 4MATIC all-wheel-drive system, coupled with 4ETS, is frequently praised for exceeding expectations, providing impressive traction and capability even in challenging conditions, such as steep and uneven mountain roads.
In conclusion, the 2018 Mercedes-Benz GLE 350 appears to offer a reasonable level of reliability, especially when considering Mercedes-Benz vehicles overall. While potential oil leaks should be monitored, particularly around the engine seals, diligent maintenance and servicing can contribute to a positive ownership experience. Owners appreciate the GLE 350’s robust build, capable 4MATIC system, and overall utility, making it a compelling option in the used luxury SUV market.
