Common Mercedes questions resolved on JustAnswer


The Experts on JustAnswer, who are available 24/7, are Mercedes specialists, and you can count on them to identify the source of a problem, provide detailed instructions for repairs, give advice on finding affordable parts and deliver second opinions on a Mercedes repair estimate offered by your local mechanic.


In fact, if your local mechanic is stumped on a problem presented by your Mercedes, an Expert on JustAnswer will usually be able to figure it out for you. It’s also a good idea to consult with JustAnswer on common problems for specific models if you’re thinking of buying a used vehicle.


Some of the problems that Mercedes Benzes are known for are suspension and steering, with seemingly fragile ball joints and control arm bushings; and the valve body and 13-pin connector in the transmission often failing.


Window regulators are a common problem on cars, but they tend to fail more on Mercedes C-class models than others. Also, Mercedes engine mounts are oil-filled, and once mileage piles up, they start to lose the oil.


Catalytic converter problems and rust are other common Mercedes repairs.


Before speaking to an Expert, be ready to explain your issue in detail, and have the model, year and VIN on hand. You’ll also be asked what you or your mechanic have already tried to do to effect your Mercedes repair.
