We tell you about the Mercedes-Benz E350’s worst years, its longevity, and everything else to know, before buying one on the used market.
Mercedes-Benz introduced the E-Class in 1993. Although it is relatively younger than its other siblings, such as the S-Class, it is Mercedes’ best-selling model, with over 13 million units sold by 2015. The Mercedes E-Class is generally more expensive than its rivals, but its elegance, smooth ride, and an abundance of features make it one of the most famous names in the sedan and coupe segments.
The new 2022 Mercedes E-Class offers impressive engine options and top-of-the-line interior qualities. However, the earlier model years still provide excellent reliability and technology for buyers on a budget. Without further ado, let’s take a look at the Mercedes E350’s worst years, its longevity, and everything else you need to know before buying one on a used market.

According to the Car Complaints website, the 2006 model has the highest number of registered owner complaints and ranks as the worst model due to costly problems at low mileage. The majority of the reports pertain to the balance shaft failing prematurely. According to the reports, owners have had to spend as much as $4,850 out of their own pockets to replace the balance shaft. On average, the problem occurred after 85,800 miles. Another frequently-reported issue with the 2006 E350 is fuel leaking from the fuel tank gasket.
Owners have mentioned smelling a strong gas odor after filling their car up. After inspection, dealers told owners they had to replace the tank gasket for around $1,200. Like the previous issue, it is another common problem occurring well below the 100,000-mile mark. Many 2007 E350 owners have complained about similar issues, making it another model year you should steer away from when buying a used car.
Over 200 owners of the 2010 model have registered complaints with the National Highway Traffic Safety Administration (NHTSA) website. About half of the reports concern malfunctioning frontal airbags. Thankfully, Mercedes provided remedies through multiple recalls. Owners can visit dealers and have the defective airbags replaced free of charge.
Several owners have complained about problems with the suspension. Some owners have reported premature fracture and corrosion on the rear suspensions; others have mentioned the air struts failing and lowering the car too much. “My car drops overnight. Some days my front would drop to the floor, some days my rear, and some days the whole car will be on the floor,” quoted one owner on NHTSA. The issue can be solved by replacing the air struts.
Reports on Car Complaints and the NHTSA indicate a problem with the 2014 Mercedes E350’s bass amplifier. According to owner complaints, the bass amplifier starts popping and crackling loudly. In some cases, owners have sensed a burning smell or saw smoke coming from the speaker system. Some owners received remedies from Mercedes dealers under warranty, but the issue occurred again.
Last but not least, several owners have filed complaints about 2014 E350’s wheels. The two common issues are the rims cracking and flat tires. Some owners have had up to six blowouts in less than three years. Although it’s a common issue, Mercedes hasn’t recalled the 2014 model for anything related to the tires.

According to reputable automobile sources, a Mercedes E350 can last anywhere between 200,000 to 250,000 miles with the original engine and transmission. Driving habits play a significant role in a vehicle’s lifespan, So if you’re the third or the fourth owner of an E350, it is safe to expect major powertrain overhauls around the 150,000-mile mark.
The average driver in America puts out roughly 14,000 miles on the odometer in a year. That translates to 14 to over 18 years of service for the Mercedes E-Class. Following the manufacturer’s official maintenance schedule is vital to keep a Mercedes E350 up and running. Some essential services include:

The star in a ring emblem has been the symbol of high-quality and long-lasting vehicles for decades, which is why we generally believe buying old Mercedes cars would be worth the investment. However, like any other car, the E350 had its fair share of problems throughout the years.
If you’re in the market for a used E350, it’s best to skip the problematic model years due to widespread issues. Besides avoiding common problems, ensure the previous owner has taken care of the recalls. The 2014 model, for example, had nine recalls about severe issues, including malfunctioning airbags, oil leaks, and loos of electric power steering assist.
