2014 Mercedes E350 Problems: Common Issues and Solutions

The 2014 Mercedes-Benz E350 is a midsize luxury car that offers impressive performance and comfort. However, like any vehicle, it has its share of issues that you may encounter. In this article, we will cover some common problems and how to address them, ensuring that your Mercedes-Benz E-Class continues to deliver the driving experience you expect.

One of the frequently reported issues is related to the car’s acceleration. Some owners have experienced a sudden decrease in acceleration, making it difficult to merge onto highways or navigate traffic. Additionally, there have been reports of rough shifting caused by internal component failure, resulting in a less-than-smooth driving experience for many E350 owners.

Engine Performance and Issues

Acceleration and Torque

When driving your 2014 E350, you may experience some acceleration and torque issues. There have been instances where drivers have reported a delay in acceleration when trying to merge into traffic or when suddenly accelerating. Your vehicle’s power may seem to drop off, giving the sensation of coasting, before picking back up again upon readjusting the throttle pressure. This may be related to the vehicle’s turbocharged engine, which can sometimes cause lag in acceleration.

Eco and Sport Modes

The 2014 E350 is equipped with both Eco and Sport driving modes. In Eco mode, your vehicle will prioritize fuel efficiency by adjusting the throttle response and transmission shift points. However, while in this mode, you might feel a slight reduction in power when compared to Sport mode. Switching to Sport mode should provide a more dynamic driving experience, as this mode enables your E350 to take full advantage of its twin-turbocharged engine and all-wheel drive 4MATIC system. Make sure to select the appropriate driving mode for your desired performance outcomes.

Vibration Issues

Some 2014 E350 owners have reported experiencing vibrations in their vehicles, particularly during acceleration or when driving at higher speeds. This could potentially be attributed to several factors, such as misalignment in the drivetrain, faulty engine mounts, or imbalances in the propeller shaft. It is essential to have your vehicle thoroughly inspected by a qualified technician if you encounter any unusual vibrations while driving to ensure the issue is properly diagnosed and resolved.

Transmission Problems

Conductor Plate Failures

One common issue with the 2014 Mercedes E350 is the failure of the conductor plate. This component is responsible for transmitting electrical signals within the transmission, and its malfunction can lead to various problems. Symptoms of a failing conductor plate include erratic shifting, delayed gear changes, and a loss of power during acceleration. To avoid potential damage to your transmission, it’s important to address conductor plate issues as soon as you notice these signs. Replacing the conductor plate may be necessary to resolve the problem and ensure smooth transmission operation.

Check Engine Light

Another transmission-related issue you might encounter in the 2014 Mercedes E350 involves the check engine light. When your check engine light comes on, it could be an indication of a transmission problem. However, it’s essential to remember that a lit check engine light can be triggered by various issues, not just transmission-related ones.

When the check engine light turns on due to a transmission problem, some common symptoms include the car shaking at any speed, a burning smell or whistling sounds coming from under the hood, and grinding when accelerating. As a precaution, take your vehicle to a professional mechanic for a thorough diagnosis to determine the root cause of the check engine light, whether it’s a transmission issue or something else. This way, you can address any problems early and avoid expensive repairs down the line.

Safety Concerns and Recalls

National Highway Traffic Safety Administration Recalls

As an owner of a 2014 Mercedes E350, it is crucial for you to be aware of any safety issues or recalls that may affect your vehicle. The National Highway Traffic Safety Administration (NHTSA) has issued several recalls for the 2014 E350, which address various issues such as electrical problems, wheel/hub issues, and interior accessory malfunctions. It is essential to follow up on these recalls and ensure that your vehicle is up-to-date with any required repairs or replacements to maintain a safe driving experience.

Advanced Lane-Keeping System

A key safety feature in your 2014 Mercedes E350 is the Advanced Lane-Keeping System, which is designed to help keep the vehicle within its lane while traveling on the road. However, there have been some reports of malfunctions or failures with this system in certain cases. These issues may vary in severity and may compromise the effectiveness of this safety feature.

To ensure that your Advanced Lane-Keeping System remains fully functional, it is important to stay informed about any potential problems or possible recalls. Regular inspections and servicing of your E350 can help identify any issues before they escalate and negatively impact your vehicle’s safety.

In summary, being informed about safety concerns and recalls for your 2014 Mercedes E350 is essential in maintaining a safe driving experience. Be sure to keep an eye out for any updates from the National Highway Traffic Safety Administration and ensure that your Advanced Lane-Keeping System is working correctly.

Final Thoughts

As a 2014 Mercedes E350 owner, you may encounter some problems such as software issues in early central gateway modules or power steering pump reservoir cracks. Staying informed about these common issues can help you solve them promptly. Remember to maintain your vehicle properly and seek professional assistance when necessary to ensure the longevity and optimal performance of your E350.
