2002 Cadillac Sls

WHEN SLOWING AT ABOUT 20 MPH TO 3 MPH THE VEHICLE JUST DIES. NO POWER STEERING OR BRAKES, ALL ELECTRICAL IN THE VEHICLE STOPS WORKING. THE VEHICLE WILL START AGAIN ONCE STOPPED, PLACED IN PARK OFTEN HAVING TO REMOVE THE KEY AND PUTTING IT BACK. AFTER OVER THREE MONTHS AND OVER 1500 MILES, WORKING WITH THE DE LA FUENTE CADILLAC DEALERSHIP, HAVING A RED BUTTON ATTACHED TO THE VEHICLE THAT I WAS SUPPOSED TO PUSH WHEN THIS HAPPENED THEY FINALLY REPLACED THE IGNITION SWITCH AND LOCK CYLINDER PART NUMBERS 12369550 AND 25725312 AT A COST OF $615.73 TO CORRECT THE PROBLEM. AFTER THE CAR STOPPED ON ME THE FIRST TIME I KEPT TO SURFACE STREETS AND DROVE AT SLOW SPEEDS. THIS PROBLEM COULD HAVE BEEN DEVIATING HAD IT HAPPENED WHILE ON THE FREE WAY. *TR

ON THREE SEPARATE OCCASIONS THIS YEAR, MOST RECENTLY TODAY (3/22/14), THE ENGINE ON MY 2003 (?) CADILLAC SLS ABRUPTLY CUT OFF, SIMILAR TO THE MUCH-PUBLICIZED RECENT FAILURES ON GM'S 2003-11 COMPACT CARS. MY CAR IS NO COMPACT, BUT I'M WONDERING IF IT USES THE SAME IGNITION COMPONENTS. IN ANY EVENT, WE WERE LUCKY TO AVOID AN ACCIDENT. AFTER THE FIRST INCIDENT, I REFERRED THE CAR TO MY TRUSTED MECHANIC, AND HE COULD FIND NOTHING WRONG. ONE FURTHER NOTE: WHEN THE ENGINE CUT OFF TODAY, ONLY *ONE* KEY WAS IN THE IGNITION, SO IT WAS *NOT* A MATTER OF THE SWITCH BEING "WEIGHED DOWN" BY AN OVERLOADED KEY CHAIN. I WILL TAKE THE CAR TO MY MECHANIC ON MONDAY AND SUGGEST THAT A NEW IGNITION SWITCH BE INSTALLED. BUT ALL THIS SHOULD SERVE AS A "HEADS UP" WARNING TO GM OWNERS WHO DRIVE NON-COMPACT GM CARS. *TR

VEHICLE WAS INSPECTED AND A CRACK IN THE ENGINE BLOCK WAS DISCOVERED. MECHANIC STATED THIS WAS VERY ODD. VEHICLE HAS 103K MILES. WATER PUMP GASKET WAS REPLACED AT 65K MILES, HEAD GASKETS, THERMOSTAT & RADIATOR WERE REPLACED AT 78K MILES AND WATER PUMP CLAMP/HOSE REPLACED AT 83K MILES. ALL THESE REPAIRS WERE MADE BY THE DEALERSHIP WHILE THE VEHICLE WAS UNDER WARRANTY. NO OTHER REPAIRS (TO MY KNOWLEDGE) WERE MADE TO THE ENGINE/COOLING SYSTEM. *TR

HEAD BOLTS PULLED OUT OF BLOCK ON A 2002 CADILLAC WITH A NORTHSTAR ENGINE. THE FIRST TIME IT HAPPENED THE CAR HAD 74,000 MILE AND WAS FIXED UNDER THE VEHICLES EXTENDED WARRANTY. THE 2ND TIME IT HAPPENED THE CAR HAD 87,000 ON IT AND THE SAME HEAD BOLT THAT WAS FIXED FAILED. THE ENGINE WAS NOT REPAIRABLE AND HAD TO BE REPLACED. THIS WAS A PATCH JOB THAT GM KNEW WAS NOT PERMANENT AND THEY NOW DO NOT WANT TO TAKE CARE OF THEIR SHODDY REPAIR PROCEDURE. *TR

This PI communicates the requirement to provide a pico file to receive diagnostic assistance from TAC.

Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.

GM is receiving damaged (cracked or broken) transmission cores returned to the reman facilities. The damage is being caused either in the removal process by the technician, or inadequate packaging or shipping. This bulletin advises the dealers to be more careful not to damage the transmissions during removal and to package the core properly for return.

This service bulletin advises of a new fuel injection cleaner kit used for decarbonizing the intake valves to correct conditions of rough idle, Crank no start, extended crank or misfire, MIL with DTCs, and explains how Top Tier fuels should be used to reduce carbon build-up.

This bulletin provides information for use on a Product Assistance Claim (PAC), which is formerly known as a Product Allegation Resolution (PAR) claim.

This service bulletin provides information for dealers/technicians on Service Programming System (SPS) Error Codes E4398, E4399, E4401, E4403, M4404, M4413, M6954, M6955, E4414, E4423, E4491, E4492, or E6961 and resolution information.
