NHTSA Complaint #10137639 — 2001 SAAB 9-5

ON A 2001 SAAB 9-5 SE (V6 ENGINE) STATIONWAGON WHILE DRIVING ON AN INTERSTATE HIGHWAY, THE CAR SUDDENLY LOST POWER AND THE CHECK ENGINE LIGHT STARTED FLASHING. AS I PULLED THE CAR OFF THE HIGHWAY ONTO AN EXIT RAMP (WITHIN LESS THAN A MINUTE OF THE MALFUNCTION), THE CAR STALLED AND A BURNING SMELL WAS DETECTED INSIDE THE CAR AFTER WHICH THE CAR WAS TURNED OFF AND PARKED. THE CAR WAS TOWED TO THE LOCAL SAAB DEALER WHERE THE IGNITION DISCHARGE MODULE ON THE REAR CYLINDER BANK WAS DETERMINED TO HAVE FAILED. FAILURE OF THE IDM ON ONLY 3 OUT OF 6 CYLINDERS CAUSED UNBURNED GAS TO BE DISCHARGED INTO THE EXHAUST WHERE IT REACTED IN THE CATALYTIC CONVERTER, CLOGGING THE CONVERTER AND STALLING THE ENGINE. THE CATALYTIC CONVERTER WAS RUINED WHICH CAUSED THE BURNING SMELL. NO FIRE WAS DETECTED. THE IDM AND CATALYTIC CONVERTER WERE REPLACED. *JB
