Buying a used luxury car, especially a German marque like Mercedes-Benz, can be a thrilling yet potentially daunting experience. While renowned for their engineering and luxury, German vehicles haven’t always enjoyed the same reputation for bulletproof reliability as their Japanese counterparts. Concerns about higher maintenance costs and potential issues linger, even in 2024. But is this reputation entirely deserved today? Recent data and historical trends offer a nuanced perspective.
Consumer Reports, a trusted source for vehicle reliability data, recently published its analysis of 26 car brands, evaluating 5 to 10-year-old models. Mercedes-Benz secured a respectable 10th place out of 26, scoring 46 in their “Reliability Verdict.” While trailing behind BMW (7th) by a narrow margin and leading Audi (16th), this places Mercedes in the mid-range. Notably, Japanese brands dominated the top spots, with Toyota and Lexus leading the pack by a significant margin. Despite being some distance from the very top, Mercedes-Benz has produced several notably reliable models within the last decade. To help navigate the Mercedes-Benz landscape, we’ve delved into Consumer Reports’ data to rank the most reliable Mercedes models of the past 10 years, offering insights for those looking at a used purchase.
To ensure accuracy and provide the most current information, the data presented here is compiled from Mercedes-Benz and reputable industry sources, with a strong focus on Consumer Reports’ Reliability Verdict rankings. Let’s explore the top Mercedes-Benz models known for their reliability in the used car market.

Reliability Verdict: 4/5
Before the GLC-Class, there was the Mercedes-Benz GLK-Class SUV, essentially a C-Class-based SUV. Introduced in 2010, the GLK received a substantial refresh in 2013, a move that proved beneficial for Mercedes-Benz.
350 4MATIC Performance Specifications

The 2013 GLK-Class, the first model year after the refresh, achieved an impressive 4/5 reliability verdict, ranking it among the more reliable modern Mercedes-Benz models. The 3.5-liter V-6 engine in the GLK 350 was highly refined and well-developed in the 2013 iteration. Interestingly, the final 2015 model year surprisingly received a lower 2/5 reliability score, despite no significant changes in powertrain or design.

Pros
- Wide range of engine choices across different trim levels.

Remarkably, the 2017 model year, the first of this fifth generation, was among these top-rated years, despite significant changes from the previous generation.
E 300 Performance Specifications
| Engine | 2.0-liter turbocharged inline-four |

- Exquisite and luxurious interior quality.
- Broad range of E-Class models to suit different budgets and preferences.

2. 2019 Mercedes-Benz E-Class
Reliability Verdict: 4/5
Despite the vast range of body styles and powertrain options in the pre-facelift fifth-generation E-Class, the turbocharged four-cylinder engine in the E 300 and E 350 models proved to be the most reliable within the lineup. The twin-turbo V-6 in the E 450 marked its final appearance in an E-Class, replaced by a mild-hybrid turbocharged inline-six in the current generation 400/450 models.
E 450 4MATIC Performance Specifications
| Engine | 3.0-liter twin-turbocharged V-6 |

| Driveline | AWD |
| 0-60 MPH | 4.6 seconds |
| Top Speed | 155 mph (limited) |
The fifth-generation E-Class’s success, despite its complexity, stemmed from its solid foundation. This generation was the first E-Class to utilize Mercedes’ modern modular chassis architecture, known as MRA (Modular Rear Architecture). MRA proved highly successful across various segments, underpinning many of the models discussed in this list.
Pros
- Enhanced driving dynamics compared to its predecessor.
- Beautifully crafted and luxurious interior.
- Wide selection of E-Class models to cater to diverse needs and budgets.
Cons
- Ride comfort is slightly firmer than the previous generation.
