Overview of popular issues

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 2017 Mercedes-benz E400 problems

The 2017 Mercedes-Benz E400 has been reported to have several common problems based on complaints from owners. These issues include a fuel leak from the high pressure fuel pump, instrument cluster failure, and transmission oil leaks.

Fuel Leak from High Pressure Fuel Pump: This is the most widespread problem found on the 2017 E-Class, with approximately 45,000 instances reported. The pump housing is known to crack, leading to fuel leaking out of it and the lines. The only solution is to replace the pump, which costs around $1,250, depending on local labor rates.

Instrument Cluster Failure: Some E-Class owners have reported issues with the instrument cluster failing, particularly around 60,000 miles. Electronic components in the gauge cluster start to wear out, causing the system to fail and not display information correctly. Replacing the gauge cluster is expensive, costing around $1,800.

Transmission Oil Leaks: Transmission oil leaks have been reported on some 2017 E-Class models, typically around 50,000 miles. The seals on the side of the transmission start to fail due to heat cycling with the car. Replacing the seals is a time-consuming process and costs around $1,000.

These problems are more prevalent in the 2017 Mercedes E-Class than in other midsize luxury sedans, leading to higher repair bills as the vehicle ages. Additionally, there have been 20 recalls on the 2017 Mercedes Benz E-Class, which is worse than many other sedans on the market. The most serious recall covers the fuel system failing due to a damaged wire harness. Other recalls cover underbody panels melting and software issues with the stereo system.

While the Mercedes-Benz E400 has a reputation for reliability, it is essential to be aware of these common problems and potential repair costs when considering purchasing a 2017 model. Regular annual maintenance costs are more expensive than most competitors, and specific components may need to be replaced as the vehicle ages, such as the windshield wiper arms, intake manifold gasket, and ABS control module.
