Recalls list

The Mercedes-Benz E-Class is a range of executive cars manufactured by German automaker Mercedes-Benz in various engine and body configurations. Produced since 1953, the E-Class falls midrange in the Mercedes line-up, and has been marketed worldwide across five generations.

Before 1993, the E in Mercedes-Benz nomenclature was a suffix following a vehicle's model number which stood for Einspritzmotor (German for fuel injection engine). It began to appear in the early 1960s, when that feature began to be utilized broadly in the maker's product line, and not just in its upper-tier luxury and sporting models. By the launch of the facelifted W124 in 1993 fuel injection was ubiquitous in Mercedes engines, and the E was adopted as a prefix (i.e., E 220). The model line is referred to officially as the E-Class (or E-Klasse). All generations of the E-Class have offered either rear-wheel drive or Mercedes' 4Matic four-wheel drive system.

The E-Class is Mercedes-Benz' best-selling model, with more than 13 million sold by 2015. The first E-Class series was originally available as four-door sedan, five-door station wagon, two-door coupe and two-door convertible. From 1997 to 2009, the equivalent coupe and convertible were sold under the Mercedes-Benz CLK-Class nameplate; which was based on the mechanical underpinnings of the smaller C-Class while borrowing the styling and some powertrains from the E-Class, a trend continued with the C207 E-Class coupe/convertible which was sold parallel to the W212 E-Class sedan/wagon. With the latest incarnation of the E-Class released for the 2017 model year, all body styles share the same W213 platform.

Due to the E-Class's size and durability, it has filled many market segments, from personal cars to frequently serving as taxis in European countries, as well special-purpose vehicles (e.g., police or ambulance modifications) from the factory. In November 2020, the W213 E-Class was awarded the 2021 Motor Trend Car of the Year award, a first for Mercedes-Benz.

Common 2014 Mercedes-benz E350 problems

The Mercedes-Benz E350, particularly the 2014 model, has been reported to have several common problems based on complaints from owners. These issues include:

Airbag and Suspension Failure: Over 200 owners of the 2010 model have registered complaints with the National Highway Traffic Safety Administration (NHTSA) about malfunctioning frontal airbags. Mercedes provided remedies through multiple recalls, allowing owners to replace the defective airbags free of charge. Several owners have also complained about problems with the suspension, such as premature fracture and corrosion on the rear suspension, and air struts failing and lowering the car too much.

Rim Cracking Issues: Reports on Car Complaints and the NHTSA indicate a problem with the 2014 Mercedes E350’s bass amplifier. The bass amplifier starts popping and crackling loudly, and in some cases, owners have sensed a burning smell or seen smoke coming from the speaker system. Some owners received remedies from Mercedes dealers under warranty, but the issue occurred again. Additionally, several owners have filed complaints about the 2014 E350’s wheels, with the two common issues being the rims cracking and flat tires.

Internal Component Failure Causing Rough Shifting: Mercedes-Benz E350 owners have reported issues with rough shifting due to internal component failure. This problem can be caused by various factors, such as a faulty transmission control module or damaged transmission solenoids.

Fuel Injector Failures: Early diesel E-Class Saloons, including the E350, have experienced fuel injector failures. These failures can lead to rough idling, stalling, and poor fuel efficiency. Mercedes-Benz has replaced these faulty injectors under warranty, but if not, the repairs can be expensive.

Electrical Issues: Some E-Class models have experienced electrical issues, such as parking sensor failures and the satnav not accepting the first five digits of a postcode. These issues can be frustrating for owners and may require costly repairs.

Power Steering Issues: The connector on the electric power steering control unit might not be properly sealed against water entry in some E-Class models. If water enters the control unit, the power steering assistance can be lost, potentially leading to dangerous driving conditions.

These common problems with the Mercedes-Benz E350, particularly the 2014 model, highlight the importance of thoroughly checking a used car before purchasing and ensuring that any necessary repairs have been made.
