In 1993, Mercedes introduced the C-class as a replacement for its 190 model. This model remained the most popular entry-level Mercedes purchase until ’97, when Mercedes moved on to launch the A-class. However, it’s still very popular today, especially when it comes to the third generation, launched in 2007. Buyers love the five door estate model and the four door sedan with its optional petrol powered or diesel engines. The newer generation also offers several other features and new Mercedes parts, like LED lighting, stop and start technology, and automatic gearboxes.
Despite its beauty, its options, and its technology, the Mercedes C-class does have its share of problems. The majority of these issues should have been fixed by Mercedes, but if you’re buying a used C-class, you may have to put in some elbow grease yourself. Make sure you inspect the car carefully before each purchase to determine if these problems still exist and will need to be taken care of.
Common Mercedes Parts and Problems
- Stability- During the test drive, pay attention to how stable the Mercedes is. Are there vibrations that impact your driving stability? If so, this could be caused by Active Body Control sensors. These will need to be replaced if you’re going to avoid safety concerns on the road.
- Engine Failure- Engine failures in C-class cars designed in 2007 are very common, and are often caused by electric connexions that are interrupted in the crankshaft sensor. This is not a do-it-yourself fix. You’ll need to take the car to a professional mechanic in order to have this problem fixed so you can restart the engine.
- Steering Problems- Driving without power steering is not safe; in fact, it can be downright dangerous. That’s what you’re facing, however, if you own a 2010 C-class that has a leak. These cars can leak power steering fluid into the pump from the fluid line. If you hear unusual noises coming from your C-class while you’re driving, replacing Mercedes parts like the pump and fluid line and replacing the lost power steering fluid will be necessary.
- Brakes- Some 2010 C-class models were fitted with brake discs that were not the right specification. If you are having issues with your brakes, replacing them immediately is essential. Otherwise, they might not be efficient enough in an emergency stop.
- Air Hoses- Faulty air hoses can cause a number of problems with other car parts, especially the engine. In many 2011 models, the air hoses were faulty, cracked, and did not work efficiently. If this is the case in your C-class, there could be two consequences: your engine could remain running, but run slowly, like it’s limping home, or your engine could shut down altogether. Preventative maintenance can catch this problem quickly. Make sure to schedule regular appointments with your local garage to have your hoses, belts, and other car parts inspected so your Mercedes can run like it should.
- Key Problems- The Mercedes C-class comes with an electronic remote key that can be an excellent convenience- unless the key suddenly stops working. Instead of taking a chance of being stranded, always make sure to carry two keys to the car at all times, as it’s unlikely both will quit working at the same time.
Are you thinking of purchasing a used Mercedes? While newer models will most likely have been inspected and repaired by the manufacturer, pre-owned models may have some Mercedes parts you’ll need to take care of. Make sure you’re prepared for this before you buy.
