Which Years Of Used Mercedes-Benz E-Class Cars Are Most Reliable?
We've rounded up two of the most reliable Mercedes-Benz E-Class years. See which ones (and which E-Class years you should approach with caution).
The Mercedes-Benz E-Class has long epitomized automotive luxury, offering a sophisticated mix of comfort, performance, and prestige. Since its debut in 1993, this mid-size marvel has set the standard for what discerning drivers expect from a high-end vehicle. While a brand-new E-Class commands a hefty price tag, the pre-owned market presents an excellent alternative for those seeking luxury on a budget.
However, not all used E-Class models are created equal. Some years shine brighter than others in terms of reliability and value.
As such, this guide aims to shed light on the most reliable Mercedes-Benz E-Class as well as the not-so-reliable ones (particularly with the ever-popular E350), drawing from sources like the NHTSA, IIHS, CarComplaints, and real-world owner experiences. Hopefully, this guide will help you get the most out of your E-Class journey.
Which is the Most Reliable Mercedes-Benz E-Class?
Below, I’ve rounded up the best and worst years of the E-Class in terms of reliability. As mentioned, this guide will mainly focus on the E350. Let’s get to it.
Avoid: 2006 Mercedes-Benz E350
If you’re going to absolutely avoid one E-Class model year, make it the 2006 E350. According to CarComplaints.com, the 2006 E350 is the worst model year of the luxury car in terms of reliability – no thanks to its massive engine issue.
The 2006 Mercedes-Benz E350 has gained notoriety for a particularly vexing engine issue, leaving many owners frustrated and paying out of pocket. At the heart of the problem lies the balance shaft, a component designed to reduce engine vibrations. However, in this model year, it’s become the source of major headaches.

Owners report the dreaded check engine light illuminated, often followed by a diagnosis that strikes fear into their hearts: balance shaft failure. This isn’t a minor hiccup—it’s a serious problem that requires extensive engine work to rectify. The repair process is so invasive that it typically involves removing the entire engine from the vehicle. Regardless of when it strikes, owners are faced with repair estimates ranging from $4,000 to a staggering $7,000.
Avoid: 2007 Mercedes-Benz E350
The following year, the E350 was another instant pass for me, mainly due to the prevalent and widely reported fuel system issue.
The 2007 Mercedes-Benz E350 has been plagued by a series of fuel system issues that have left owners fuming – literally. Many drivers report a strong gasoline odor permeating the cabin, especially after filling up. This isn’t just unpleasant; it’s potentially dangerous. Some have experienced fuel leaks near the exhaust, raising fire hazard concerns.
The problems don’t stop there - fuel pumps failing unexpectedly, causing stalling at highway speeds, and inaccurate fuel gauges have also been reported. These issues persist even after repairs, frustrating owners who expected more reliability from a luxury brand. The widespread nature of these complaints suggests a systemic problem rather than isolated incidents.
Buy: 2009 Mercedes-Benz E350
The 2009 version is a good candidate for the most reliable Mercedes-Benz E-Class car. For starters, there are significantly fewer complaints than in both model years highlighted above.
The 2009 Mercedes-Benz E350 seems to have inherited a persistent fuel system gremlin from its predecessors. Owners report a strong gasoline odor, particularly after refueling, that lingers both inside and outside the vehicle. This isn’t just about the smell; it raises serious safety concerns about potential fuel leaks. Some drivers have observed actual fuel dripping near the tank area, while others experience rough running and occasional no-start situations.
Despite these worrying issues, it’s worth noting that many E350s from this year still provide reliable service.
THE MERCEDES-BENZ E-CLASS YEARS TO AVOID
We take a look at the Mercedes-Benz E-Class years to avoid when shopping at the used car market.
Caution: 2010 Mercedes-Benz E350
The 2010 Mercedes-Benz E350 was caught in the crosshairs of the infamous Takata airbag recall, a safety issue that plagued numerous automakers. While this model year generally received fewer reports of major mechanical problems, the airbag recall cast a long shadow. Owners expressed frustration with extended wait times for replacement parts, leaving them uncertain about their vehicle’s safety. Some even limited their driving due to concerns over potentially faulty airbags.
However, it’s important to note that if the recall has been properly addressed, the 2010 E350 can still be a solid choice in the used luxury car market.
Caution: 2011-2013 Mercedes-Benz E350
Building on the earlier discussion of the 2010 E350’s airbag issues, it’s important to note that the Takata recall saga continued to affect subsequent model years. The 2011-2013 Mercedes-Benz E350s were also caught in this wide-reaching safety net, further complicating matters for the German luxury brand.
While these later models maintained the E-Class reputation for refinement and performance, the lingering airbag concerns overshadowed their appeal. Potential buyers should approach these years with a mix of excitement and caution. The allure of a more recent E350 is undeniable, but so is the need for thorough due diligence.
Before falling in love with that sleek silver E350 model, make it a priority to verify its recall status. A quick VIN check could be the difference between a dream car and a potential nightmare.
THE MERCEDES-BENZ S-CLASS YEARS TO AVOID
We highlight the Mercedes Benz S-Class years to avoid and offer insights into why they’re not worth your time and money.
Avoid: 2014 Mercedes-Benz E350
Unfortunately, the 2014 E350 has a little bit of everything when it comes to reliability woes. Aside from the problems mentioned above with the airbags, this model year also struggled with other issues.
Owners report a symphony of electrical gremlins, with the audio system taking center stage in this drama. Picture this: you’re cruising down the highway when suddenly your speakers start popping like firecrackers, followed by an acrid smell of burning plastic. It’s not just annoying – it’s downright alarming.
But the troubles don’t stop there. Some drivers have experienced intermittent failures of critical systems like lane-keep assist and ABS, turning their premium rides into potential hazards. Others report mysterious trunk openings as if their E350 has developed a mind of its own.
Buy: 2016 Mercedes-Benz E350
Lastly, the 2016 E350 is another excellent option for buyers looking for the most reliable Mercedes-Benz E-Class. As the final year of the W212 generation, Mercedes had ironed out many kinks, resulting in a well-refined machine. Owners report few issues with the advanced tech features, and even the more complex systems like Distronic Plus seem to hold up well. While some may find the Sport model’s ride a bit firm, the highway comfort is exceptional.
