Known issues on the 2004 CL230. Complaints filed against the wider 2004 C230 models number 31, with the electrical system at the top, followed by engine and engine cooling and then seat belts. The same 2004 C230 models were the subject of three recalls. In two, certain vehicles had a sunroof glass panel that might not be held in place and could fly off; in the third, certain vehicles could see the bond holding the glass to its sliding frame weaken until the panel let go. Those filings belong to the wider line. The manual supplies the procedures, torque values and wiring diagrams for the seat belt, electrical and sliding roof systems.
