NHTSA Complaint #11699778 — 2015 VOLKSWAGEN GOLF SPORTWAGEN

PTC auxiliary heater core connection point failure . It was reported that the wrong type of metal was used for the main electrical connection point for this part causing significant over heating further leading to melting and burning plastic. This then introduces potentially dangerous fumes into the vehicle cabin via the HVAC system. If unaddressed this would likely cause fire damage. The problem has been reproduced by multiple vehicle owners and happens during cold conditions as it supplies heat to the cabin prior to the engine hitting optimal operating temperatures. No warning messages or codes are thrown as a result of this issue. It is a hazard and could cause harm to operators of the vehicles affected.
