The midsize Mercedes-Benz E-Class luxury line gets top scores from JD Power for powertrain dependability as well as for its body/interior, though it gets a tick lower for feature/accessory and overall dependability. Consumer Reports is a bit less generous here, giving the 2014 E-Class a four out of five score for reliability, with power equipment and electronics getting only middling scores. Of note, the E-Class was redesigned for 2016 and both the current and 2014 versions are CR-recommended.
