One problem related to timing tensioner has been reported for the 2014 Mercedes Benz E350. The most recently reported issues are listed below.
Car was purchased from mercedes dealership in 2016 and has only been seen by mercedes dealerships for service. In 2019, a oil seepage was noted during annual maintenance however no repair or diagnosis was performed. At this time, the car only had 36,000 miles on it. In Nov of 2020, the car was taken in to the same dealership for annual service. The car now only had 40,000 miles but was given a 50k service. At the time of service, the technician explained that oil was leaking from the engine cover and had also contaminated the drive belts. Repairs to engine cover, belt and tensioner came to $3000+. Dealership had no explanation for why after such a short time with limited driving, the car had such significant repairs needed. A tire pressure sensor had also failed. From my research this issue is known, however should not be happening to a car beginning only 5 years after of manufacturing with less than 37,000 miles.
