One problem related to front seat belt buckle assembly has been reported for the 2003 Mercedes Benz C230. The most recently reported issues are listed below.
2003 mercedes C230. Seat belt comes un-buckled at random times while driving and dealer will not fix because defect cannot be duplicated at dealership. I note that the 2004 models were recalled for this same defect. Why doesn't the recall cover the 2003 model?.
