There is a reason why Mercedes-Benz is one of the most widely known car brands on the planet right now. It is because, Mercedes creates a long list of gorgeous, eye-popping vehicles. But just as beauty is only skin deep, we must look deeper than how the Mercedes looks on the outside.
When it comes to the inside of most Mercedes-Benz’, there have been enough issues to disappoint many users. So before you decide on your next Mercedes, keep the following criticisms in mind before you end up being disappointed.
Thrust Link Bushings Known To Crack Open
Thrust link bushings refer to a rubber cylinder filled with hydraulic fluid that can be found on the front suspension. These are extremely vital to the car itself and if damaged can spell disaster for the car.
These same bushings have been known to crack open unexpectedly. Causing them to leak out all the fluid inside it and spilling it internally in the car. Losing this fluid usually leads to a bumpier drive and potential tire wear.
Air Suspension Failure
There have been several reported issues with Mercedes when it comes to the more AIRMATIC features of the Mercedes. But the most frequent complaints come regarding the air suspension.
Mercedes-Benz first introduced air suspension to the S-Class W220 in the year 2000. In theory, the company should have perfected this feature by now. But Benz vehicles continue to be plagued by failing air suspension bags and air suspension relays.
The more often a car is used the more the engine typical wears down due to use. It’s recommended that spark plugs get replaced after that point. This is normal, nothing wrong there … except for the fact that some Mercedes drivers run into engine misfiring before they even hit 100,000 miles on their vehicle.
This can be fixed the same way with most cars, change the spark plugs. But seeing how fast Benz drivers run into this issue on their engine is alarming.
Every Mercedes-Benz model made after 1995 has imported an electronic transmission system. In terms of updating technology, it is a great system and innovation for the Benz, but a common issue is that the electronic transmission system often leads to graphite build-up caused by an oil leak.
An oil leak can be caused the same way that oil leaks in more cars are caused. But because of the frailness of the electronic transmission system, an oil leak in a Mercedes-Benz offers a much more worrying situation.
Oil leaks are not the only common leaks that Benz users tend to run into. The Mercedes-Benz has also been prone to running into differential leaks. Typically when it comes to E class vehicles in the Benz’s lineup with high mileage on them.
These kinds of leaks are normally coming from the pinion seals, axle seals, or differential covers. This is caused by these components becoming weaker over time due to age. Drivers are more likely to run into these issues while driving a Mercedes than most other brands.
The average car is susceptible to rust issues during lack of usage, but Mercedes has been known to rust easily and quickly. What is just as shocking is knowing just how many places on the vehicle that rust can show up.
The Mercedes-Benz has been known to accumulate rust
- Along its floorboards
- Under the wheel wells
- On the bumpers
- Front fenders
- Underneath the driver’s
- Passenger’s seats
- Behind the license plate
Low Brake Pressure
A lot of Mercedes-Benz vehicles are equipped with Sensotronic Brake Control. This refers to an electro-hydraulic braking system that offers a high-pressure brake fluid supply that proves extremely useful in emergency braking situations. The only problem here is when the SBC system fails, which, has been prone to happen with Mercedes vehicles.
This is where the car slows and stops as opposed to actually braking when it is instructed to do via the brakes.
Worn Out Catalytic Converters
More often than not, a Mercedes has been known to wear out its catalytic converters after merely 60,000 miles. Catalytic converters have been known to prove either ineffective or suffer from a simple clogging. Which opens the door for a whole new bevvy of other issues, such as engine misfires and hesitations. This also causes the check engine light to come on until the issue is fixed.
Even worse, depending on the model, fixing the catalytic converter could cost up to £4,000, if not more.
Insulation Damages Easily
This is specifically an issue that Mercedes users need to deal with in hot, western regions of the world. The heat emanating in these places affects the insulation on Benz’s harness wiring.
The overexposure to heat causes the insulation within the Benz to crack open and, damage the engine. It’s hard to take precautions to protect the Mercedes when the entirety of each state is hot all year round. Maybe buying a Benz in a hot area is just a bad idea?!
To its credit, Mercedes vehicles have a stronger 5-speed transmission than most vehicles. But the components within it tend to have a lot of issues. Many users tend to report on how the 13-pin connector and the transmission’s valve body have problems that further damage the car itself.
In the case of the 13-pin connector, for whatever reason, it typically leaks out the transmission fluid. This in return spills out into the wiring harness and damages the control module. The valve body, meanwhile, may lead to bad shifting.
