The Mercedes Benz C-Class is one of the many high-quality vehicle lines that the car manufacturer is well-known for. The C240 is one of the cars in this lineup that's been regarded as a dependable compact executive vehicle. This vehicle is made in Mercedes' Sindelfingen assembly plant in Germany, a factory that has been awarded high quality ratings by J.D. Power. However, some C240s have been recalled in the past because of common problems with the vehicle. Here are some of the more significant problems the manufacturer had to deal with over the years. It is important to note that most of them are related to passenger safety.
A seat belt is a big part of passenger safety, and its lock is the key part that determines how effective it is. In a C240 there is a high chance that the seat belt buckle may not lock properly. In the event of a crash, the seat occupant's risk of injury is increased. More than 4,000 C240s were recalled in 2003 for having rough areas on the seat belt locks. It's been found out that the presence of a burr on these locks could prevent the seat belt from locking.
It isn't immediately evident, but Mercedes Benz C240s have airbag triggers that don't activate consistently during a low-speed crash. This manufacturer fault can be particularly dangerous, since drivers don't usually wear seatbelts when driving slowly. The C240 failed low-speed tests conducted by the NHTSA in 2006.
That year, approximately 61,000 vehicles have been reported as having faulty airbags. Mercedes Benz recalled the vehicles and replaced them with new airbags free of charge.
Mercedes is known for producing accurate electrical systems on cars, but the 2005-2008 C240s had a software calibration flaw that proved to be dangerous during a collision. Cars are programmed to cut off power to the fuel system during an accident to prevent fire or an explosion. The software calibration on a few C240s did not send a crash signal to the fuel pump during a crash. This caused the C240's fuel pump to keep running and delivering fuel during an accident even when it was designed not to.
Although it affected a relatively small number of cars, Mercedes recalled the faulty vehicles and fixed them free of charge.
