NHTSA Complaint #10130261 — 2001 SAAB 9-5

I HAVE AN '01 9-5 AND HAVE HAD THE DI CASSETTES FAIL TWICE, ONCE CAUSING DAMAGE TO THE CATALYTIC CONVERTER. THE FIRST DIC FAILURE WAS ON 8/19/2003 AT 62,453 MILES WITHOUT WARNING. I WAS DRIVING 45 MPH AND THE VEHICLE STALLED WITHOUT WARNING AND WOULD NOT RESTART. I HAD ONE DI CASSETTE AND 6 SPARK PLUGS REPLACED ON 8/20/2003. ON 12/22/2003 (4 MONTHS LATER) WITH 64,080 MILES ON THE VEHICLE, WHILE DRIVING 60 MPH ON THE HIGHWAY, THE ENGINE LIGHT CAME ON AND SUDDENLY I WAS ONLY ABLE TO TRAVEL AROUND 20-30 MPH WITH MUCH SHAKING TO THE VEHICLE. THIS DIC FAILURE CAUSED THE CATALYTIC CONVERTER TO BURN UP. THE TECHNICIAN SAID THAT BOTH DI CASSETTES HAVE TO BE REPLACED WHEN ONE FAILS OR YOU RUN THE RISK OF RECURRENCE. I HAD TWO DI CASSETTE, ONE CATALYTIC CONVERTER, ONE THERMOSTAT, AND SPARK PLUGS REPLACED ON 12/23/2003 (ONE DIC WAS CREDITED BECAUSE OF THE PREVIOUS WORK ON 8/20/2003). I WAS ADVISED ON 7/22/2005 THAT I DO NOT HAVE THE LATEST SAAB 9-5 TRIONIC UPDATE THAT INCLUDES CHANGES TO PROTECT AGAINST DI CASSETTE FAILURES. PERHAPS THERE WERE ERRORS IN THE OLD CODE THAT WERE CAUSING ALL THE DIC FAILURES, OR PERHAPS THIS IS AN UPDATE TO ADD FAIL-SAFES TO MINIMIZE THE CHANGE OF DIC FAILURES.
