In 2019, Subaru service bulletins began flagging the S62 code as a hidden transmission heat-seal issue that can masquerade as an engine misfire. The S62 does not point to a spark plug failure; instead it signals a temperature overrun in the D4ST dual-clutch that the ECU misinterprets. Understanding this nuance

Federal regulations require OBD systems to flag any fault that could push tailpipe emissions above 150% of the certified limit. In the United States, on-board diagnostics (OBD) is mandatory for emissions compliance, and today’s fleets are turning that requirement into a competitive advantage. By leveraging real-time fault-code data, operators
