2018 Mercedes-benz E400 problems
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 2018 Mercedes-benz E400 problems
The 2018 Mercedes-Benz E400 has several common problems reported by its owners. These problems are related to the engine, brakes, electrical system, lights, steering, body/paint, and seat belts/airbags.
One of the most common problems reported is idling roughly, which affects the engine. This issue is caused by a worn-out mass airflow sensor or a damaged throttle body. Replacing the mass airflow sensor costs around $350, while a new throttle body is over $1,000 depending on local labor rates.
Another common problem is related to the brakes. The windshield wiper motor tends to wear out quicker than on some other cars, and has to be replaced. Changing out the windshield wiper motor is roughly $700.
The electrical system of the 2018 Mercedes-Benz E400 also has some issues. Excessive battery drain is mentioned by some E-Class owners in the first 10,000 miles. There are a lot of electrical accessories on the E-Class, and in some cases they stay on even when the engine is off, which drains the battery quickly. Diagnosing the source of the battery drain costs around $150, while fixing it can cost $50 to $800.
The lights of the 2018 Mercedes-Benz E400 also have some issues. Some owners have reported wind noise on the driver's door at the top, which is caused by maladjustment.
The steering of the 2018 Mercedes-Benz E400 also has some issues. Some owners have reported steering rack issues, which can cause the turbos and engine to lock up. Mercedes will replace the line on affected models for free.
The body/paint of the 2018 Mercedes-Benz E400 also has some issues. Some owners have reported maladjustment, which can cause air and water leaks. This can affect the seals and/or weather stripping, windows, locks and latches, doors or sliding doors, tailgate, trunk or hatch, mirrors, seat controls (power or manual), seat belts, sunroof, convertible top, and glass defect.
The seat belts/airbags of the 2018 Mercedes-Benz E400 also have some issues. Some owners have reported that the convertible top strings started breaking and unraveling, which can affect the seat belts and airbags.
Overall, the 2018 Mercedes-Benz E400 has several common problems reported by its owners. These problems are related to the engine, brakes, electrical system, lights, steering, body/paint, and seat belts/airbags. It is important for owners to be aware of these issues and to have them addressed by a qualified mechanic to ensure the safety and longevity of their vehicle.

- Manufacturer: Mercedes-Benz USA, LLC
- Components: BACK OVER PREVENTION:DISPLAY FUNCTION
- Summary: Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2018-2021 CLA-Class, GLE/GLS-Class, A-Class, C-Class, E-Class, E-Class Coupe/Convertible, GLA/GLB-Class, GLC-Class, and CLS-Class vehicles.

- Consequence: An inoperable rearview camera display reduces the driver's rear view, increasing the risk of a crash.
- Remedy: Dealers will update the rearview camera software, free of charge. Owner notification letters were mailed July 15, 2022. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2022060007.

- Summary: Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2017-2019 C300, E300, 2018-2020 CLA250, 2020 CLS450, AMG E53, AMG GT53, GLE450, 2018 AMG E63, AMG GTA, 2017-2020 GLA250, GLC300, 2019 GLC350, AMG GLC43, 2017-2018 GLE350, 2019 AMG GLC 43, GLC350, GLE400, 2017 GLS450, S550, C300 Cabrio, and 2018-2019 S560 vehicles. On June 18, 2021, an additional 9 vehicles were added, including certain 2021 GLA250, GLC300, 2018 S450, E400, and 2017 CLA250 vehicles. The communication module might have been inadvertently deactivated during a service visit, which could have disabled the Emergency Call (eCall) function.
- Consequence: A disabled eCall system would prevent a vehicle occupant from contacting emergency services through the call center in an emergency, potentially delaying emergency responders and increasing the risk of injury.
- Remedy: MBUSA will notify owners, and dealers will inspect the communication module and activate it, if necessary, free of charge. The recall began March 31, 2021. Letters for the owners of the 9 additional vehicles were mailed July 9, 2021. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2021030005.
- Manufacturer: Mercedes-Benz USA, LLC
- Components: ELECTRICAL SYSTEM:SOFTWARE
- Summary: Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2016 - 2021 CLA-Class, GLA-Class, GLE-Class, GLS-Class, SLC-Class, A-Class, GT-Class, C-Class, E-Class, S-Class, CLS-Class, SL-Class, B-Class, GLB-Class, GLC-Class, and G-Class vehicles.

The software in the replaced instrument cluster may cause the seat belt warning system to not operate properly, only displaying a solid warning light if either the driver or passenger seat belt is unfastened, instead of a blinking light with an audible tone.
- Consequence: Without the audible tone and blinking warning light to remind the front seat occupants that their seat belts are not buckled, they may forget to buckle their seat belt, increasing their risk of injury in the event of a crash.
