Mercedes-Benz E-Class: Years to Avoid and Best Years (Engine & Transmission)
Mercedes-Benz E-Class problems by model year, from 1,800 owner complaints filed with NHTSA. For each year: the share of complaints about the engine, transmission or fuel system, how many there were, and the recalls.
Worst years to avoid: 2017 (52%, 75 drivetrain complaints), 2012 (38%, 53 drivetrain complaints) and 2019 (35%, 15 drivetrain complaints). 6 of the 10 Mercedes-Benz E-Class years we score have an elevated engine, transmission or fuel-system complaint share.
Best years on this measure: 2015 (18%), 2014 (23%) and 2013 (25%). 2015 rests on fewer than 60 complaints, so treat it as provisional. A low share means owners complained about other things more than the drivetrain, not that nothing ever fails.
The sharpest change between consecutive years is from 2016 (28%) to 2017 (52%), up 24 points. The complaint pattern shifts at that year, so check which year the car in front of you is.
By raw volume, the 2017 drew the most drivetrain complaints (75 of 380 across the scored years). Volume also tracks how many were sold and how long they have been on the road, which is why the share, not the count, sets the verdict.
2021, 2022 and 2023 have fewer than 25 complaints on record so far, too few to score. Newer cars have had less time to collect complaints.
Engine and transmission complaint share, 2010–2023
Share of relevant owner complaints about the engine, transmission or fuel system. 33% is elevated, 40% high, 60% very high. A dash means too few complaints to score.
