We've updated our reliability stats for the E-Class to include owner experiences through June 30, 2016. Reliability information elsewhere is based on a survey conducted in April 2015--well over a year ago.

Repair frequencies, in terms of repair trips per 100 cars per year:

2015 E-Class: 51, high, very small sample size
2014 E-Class: 26, moderate
2013 E-Class: 15, low, small sample size
2012 E-Class: 55, high
2011 E-Class: 43, moderate
2010 E-Class: 65, moderate

We have two additional statistics, "Nada-odds" and "Lemon-odds", to indicate the percentage of cars with no repairs in the past year and those that required 3+ trips to the repair shop:

2014 E-Class: 85, < 1

We'll have further updates in November and next February. The more owners participate, the more comprehensive and precise these will be.
