Are you thinking about buying a Mercedes? If you’re looking to buy one, you need to take into account something other than how powerful and fast a Mercedes is. You also have to take a look at its reliability.

It’s not the most exciting topic, but you must do some research into reliability before buying a new car. Cars that aren’t reliable cause their owners no end of frustration, and they can cost a lot of money.

Historically, German cars have been dogged by question marks over their reliability, but what about Mercedes? Are Mercedes reliable cars? Or are you going to find that your brand new C-Class is going to be spending far more time off the road than on it? In this article, we’re going to investigate claims of reliability and how they affect the brand.

Is Mercedes reliable?

When you begin your search into the reliability of any product, including a new car, consumer reports are a good starting point.

Every year, Which? conduct a reliability survey. They contact 1,000s of consumers, requesting information about their vehicles. The reports provide an interesting picture of their reliability and the problems experienced when driving them.

In the Which? Reliability Survey, newer Mercedes was awarded 3-stars in the site’s 5-star ranking. This is not hugely impressive for newer vehicles, as it means they were found to be just average.

Owners of older vehicles experienced no specific issues, however, the manufacturer still only earned an average rating of 3-stars.

Why is Mercedes unreliable?

So, we’ve established that Mercedes isn’t considered one of the more reliable manufacturers. But why is this the case?

It is interesting to note that a large number of the more unreliable vehicles come from premium automakers. However, in recent years this has changed, with Maserati and Bentley taking their place.

One of the main reasons that premium brands have been awarded poor reliability scores are down to the fact that they include a great deal of new technology. Which means that there is a lot more that can go wrong. One of the most common issues experienced by owners is with non-engine electrics.

Mercedes vehicles are packed with new technology and earlier this year the new MBUX system including a top-of-the-range infotainment system was introduced in the latest A-Class models. This system was later introduced in other models from the German manufacturer.

Mercedes is quick to adopt new technology, however, the more that is added to it, the more there is to go wrong.

Mercedes actually produce fantastic engines. As long as you maintain your vehicle exactly when you are meant to, your car should hold up, in theory. The problem is that the more technical bits might go wrong.

How reliable is the Mercedes A-Class?

As with any brand, some Mercedes models are more dependable than others.

In the Which? Reliability Survey, the A-Class earned 3-stars. This is an average score, so on par with the scores earned by the E-Class, and higher than Mercedes’ poorer scoring GLC model. According to the data gathered from survey participants, owners of the petrol version experienced more problems than those who drove diesel. The most commonly reported issue was related to airbags at 20%. Another problem that was regularly reported by owners was connected to getting the petrol model started.

Owners of older models also experienced issues with safety equipment, with 14% reporting they had problems with their airbags.

Overall, looking at the results the Mercedes A-Class is average when it comes to being a dependable vehicle.

How reliable is the Mercedes E-Class

The Mercedes E-Class is the most popular range of vehicles that Mercedes produces.

When Which? conducted their annual reliability survey, the newer E-Class models were awarded 3-stars out of 5. When asked about their experiences over the 12-months running up to the survey. 33% of owners reported that it had been necessary for them to take their vehicles in for a service. 10% stated that they had problems with the exterior trim, while 10% reported problems with their fuel systems.

The E-Class has experienced a few large issues over the last decade, having had problems with the fuel injection system and the airbags which made it necessary for Mercedes to conduct a mass recall to repair them.

Should I buy, lease or hire a Mercedes?

Mercedes have the reputation of making high-quality, luxury vehicles that are a pleasure to drive. So, it’s understandable that they are one of the top vehicles of choice when it comes to business cars.

If you love the look of a Mercedes and have often dreamed of parking one on your driveway, then what’s stopping you?

If you’ve been thinking about getting a brand-new Mercedes, whether you like the look of them, have long-admired the reputation of the brand and find their stylish exterior fit your needs, then a lease might be the perfect route for you to take. And, even better, if you decide to go with a fully maintained lease you will have peace of mind that any of the issues that may occur with your Mercedes are covered. So you can have all of the comfort and luxury associated with the excitement of one of these German classics minus the anxiety.

On one hand, we can applaud them for the fact that they adopt new technology into their models quickly. But electrics are a core issue they are reported for when it comes to common problem areas and, therefore, a reason why they often have a low-reliability score.

However, they do have an impressive score for build quality and overall performance. So it depends on what is more important to you as a driver and buyer.

Ultimately, Mercedes-Benz still makes great cars that are worth the money, but we can’t ignore that the new technology could lead to problems later down the line.
