Usually, when we think of Mercedes-Benz, we think of exceptional performance and luxury. Most of the time, the carmaker lives up to our expectations, but that was not the case with the 2015 Mercedes-Benz C-Class. When it was new, the 2015 C-Class sedan made a big splash because of its striking redesign and tech features. But over time, the model became known for its poor predicted reliability ratings and owner dissatisfaction. 

Consumer Reports gave the 2015 C-Class the lowest reliability score

Reliability is always a key factor when choosing a new car, but it’s even more important when you’re shopping for a used one.  Predicted reliability ratings are indicative of how models have performed in previous years and how they are likely to perform in the future.  All this to say that the 2015 C-Class is very unreliable by these measures.

Based on the model’s history and customer surveys, the C-Class has about 17 potential trouble spots. These trouble spots range from the engine, brakes, power equipment, and the electrical unit. The 2015 C-Class also received a low-reliability score from J.D. Power. 

11 total recalls 

There has been 11 total recalls on the 2015 C-Class, which of course contributes to the whole poor reliability factor. The first recall issue concerned the steering. There was a sliding shaft that could become separated from the steer coupling socket which would cause noises and steering backlash; the worst-case scenario was losing steering control. Another steering issue related to the electric power-assist system which could also lead to loss of control and crashes.

Some customers reported issues with glaring headlights which could potentially cause oncoming drivers to crash. Other problems related to the engine: if the fuel delivery module became loose, it could increase the risk of fire. There were potential issues with the fuel pump which also increased the likelihood of crashes.  

The list goes on and on. Other issues included the engine overheating which could also lead to fire, problems with the rear axle that could lead to crashes, and even problems with the airbags. Mercedes also recalled this model because of a software issue that could potentially report the wrong vehicle location which would delay emergency responders and put passengers more at risk.

Other drawbacks 

Aside from the reliability issues, the 2015 C-Class is also very expensive to maintain. U.S. News estimates that the five-year cost for insurance, gas, and maintenance for the model is about $31,517 and that’s just the average cost. You should also know that the standard four-cylinder engine is uncharacteristically loud and the in-car electronics are cumbersome.

Just don’t do it

While the 2015 C-Class lineup looks handsome on the outside and boasts an upscale interior, it’s just not worth the headache. There are far too many issues and the cost of ownership is quite expensive. If you are set on owning a discounted C-Class model, the 2016 and 2018 versions are better to buy used. It also might be worth looking into the 2015 BMW 2-Series or the 2015 Audi A4.
