NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE04-061.
ON NOVEMBER 16, 2004, GM NOTIFIED NHTSA THAT IT WILL CONDUCT A SAFETY RECALL OF 178,798 MODEL YEAR (MY) 2003 AND 2004 SATURN ION SEDAN VEHICLES FOR INOPERATIVE FRONT TURN SIGNAL/DRL BULBS.GM STATED THAT TEMPERATURES IN THE LAMP ASSEMBLY EXCEED THE MATERIAL SPECIFICATION FOR THE BULB SOCKETS AND BULB BASE SLEEVES, WHICH CAUSE DEFORMATION.THE DEFORMED SOCKETS CAN CAUSE LOSS OF BULB AND SOCKET CONTACT.THE DEFORMED SLEEVES CAN CAUSE STRESS CRACKS TO FORM ON THE BULB THAT CAN LEAD TO PREMATURE BULB FAILURE.THE RECALL REMEDY IS TO REPLACE THE FRONT TURN SIGNAL/DRL BULBS AND INSPECT FOR VOLTAGE-REDUCING JUMPER (WHICH REDUCES TEMPERATURE IN LAMP ASSEMBLY) AND ADD IF NOT PRESENT.SEE NHTSA RECALL NO. 04V547 FOR DETAILS.THE BULBS FOR THE TURN SIGNAL/DRL IN THE SATURN ION SEDAN AND ION COUPE ARE IDENTICAL IN DESIGN AND MADE BY THE SAME SUPPLIER.BUT THE TURN SIGNAL/DRL SOCKETS, WIRING AND HOUSING ARE DIFFERENT IN DESIGN FOR THE SEDAN AND COUPE, AND WERE MADE BY DIFFERENT SUPPLIERS.GM'S DATA SHOWS A LOWER OPERATING TEMPERATURE FOR THE COUPE'S LAMP ASSEMBLY THAT DOES NOT EXCEED THE MATERIAL SPECIFICATION FOR THE BULB SOCKET AND THE BULB BASE SLEEVE.COMPLAINT AND WARRANTY RATE IS ALSO LOWER FOR THE COUPE.HOWEVER, GM'S WARRANTY DATA SHOWS A CONTINUING TREND FOR THE COUPE.THIS PRELIMINARY EVALUATION HAS BEEN UPGRADED TO AN ENGINEERING ANALYSIS (EA04-035) FOR FURTHER INVESTIGATION OF THE MY 2003 AND 2004 SATURN ION COUPE VEHICLES.
Vehicles and equipment listed for this investigation
NHTSA's investigations file lists these vehicles and equipment for Preliminary Evaluation PE04-061. A listed model year means only that an investigation names it; it says nothing about any particular vehicle. Model years with a try.vin recall page link to that page's NHTSA investigations section.

All Saturn recallsWhat an NHTSA investigation is
NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.
An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
