THE VEHICLE INTERMITTENTLY LOSES ENGINE/ ELECTRICAL POWER WHILE DRIVING. WHEN THE POWER LOSS OCCURS, BRAKES AND STEERING LOSE PROPER FUNCTIONALITY CREATING A THREAT TO THE DRIVER AND PASSENGERS AS WELL AS OTHER MOTORISTS. THE VEHICLE THEN IS UNRESPONSIVE TO THE PROPER STARTING PROCEDURE. RESTARTING THE VEHICLE IS INCONSISTENT. IT MAY START IMMEDIATELY UPON COMMAND OR IT MAY CAUSE A THEFT PROCEDURE TO INITIATE. THE VEHICLES DIC WILL POSSIBLY SHOW THE FOLLOWING PROMPTS JUST BEFORE THE SHUTDOWN FAILURE OCCURS; SERVICE VEHICLE SOON, SERVICE STABILITY SYSTEM SOON, SERVICE A/C SYSTEM SOON. DURING THE SHUTDOWN FAILURE, NO ELECTRICAL COMPONENTS ARE OPERABLE BUT POWER IS STILL AVAILABLE TO THE CAR ALLOWING THE DIC TO PROMPT 'NO FOB DETECTED' OR 'THEFT ATTEMPTED' AND THE FOB WILL INTERMITTENTLY ALLOW YOU TO SEND LOCK/ UNLOCK COMMANDS DURING THE SHUTDOWN FAILURE. THE FAILURE HAPPENS IN ANY SCENARIO AND IS INTERMITTENT IN THE ASPECT OF NO FAILURE OCCURS FOR A WEEK OR 5 FAILURES OCCUR IN A DAY. I CANNOT DETERMINE WHEN THE FAILURES BEGAN HAPPENING CONSIDERING I PURCHASED THE VEHICLE USED WITH 155000 MILES AND THE FAILURES HAVE BEEN HAPPENING SINCE DAY 3 OF MY OWNERSHIP. THE VEHICLE IS CURRENTLY AT A MIDLAND MICHIGAN CADILLAC DEALERSHIP BEING DIAGNOSED.

I WAS DRIVING ALONG A CITY ROADWAY WHEN THE VEHICLE'S STABILITY, TRACTION CONTROL, AND ENGINE LIGHT CAME ON SIMULTANEOUSLY WHEN ALL OF A SUDDEN THE VEHICLE JUST STOPPED, ALMOST CAUSING THE CAR BEHIND ME TO COLLIDE WITH MY VEHICLE. I CALLED THE DEALER, LAWLEY'S GM STORE IN SIERRA VISTA, AZ. WHERE I HAD JUST PURCHASED THE VEHICLE AND TOLD THE SERVICE MANAGER WHAT HAPPENED...HE SENT A TOW TRUCK TO PICKUP THE VEHICLE AND AFTER INSPECTING THE VEHICLE AT THE DEALERSHIP TOLD ME IT WAS THE THROTTLE BODY NEEDING REPLACEMENT...I BOUGHT A NEW ONE AND HAD IT INSTALLED. RAN FINE FOR A COUPLE OF WEEKS AFTER WHICH THE VEHICLE BEGAN STALLING WHILE DRIVING ON A CITY ROAD WHEN THE SAME THING HAPPENED AGAIN, BUT THIS TIME WHEN THE VEHICLE STOPPED WITHOUT ANY WARNING CAUSING THE VEHICLES BEHIND ME HAD TO SWERVE AROUND ME ALMOST CAUSING ACCIDENTS WITH ONCOMING VEHICLES. CALLED THE DEALER AGAIN, HAD THE VEHICLE TOWED IN AND THIS TIME WAS TOLD THAT THE VEHICLES COMPUTER WAS NOT PROGRAMMED RIGHT AND THAT IT ALSO NEEDED THROTTLE BODY HARNESS...BOUGHT THE HARNESS AND HAD IT INSTALLED AS WELL AS THE DEALER REPROGRAMMING THE COMPUTER. CAR DID WELL FOR A FEW MONTHS WHEN IT HAPPENED AGAIN (VEHICLE STOPPING UNEXPECTEDLY), THIS TIME APPROACHING A MAJOR CROSSWALK AND ONCE AGAIN CAUSING THE VEHICLES BEHIND ME TO COME A ABRUPT STOPS, FORTUNATELY A CITY POLICE VEHICLE WAS ON THE OPPOSITE SIDE OF THE CROSSWALK AND THE OFFICER WITNESSED WHAT HAPPENED, PUT HIS VEHICLE'S EMERGENCY LIGHTS ON AND CAME OVER TO HELP ME PUSH OUT FROM THE STREET TO A WALGREEN'S PARKING LOT WHERE I ONCE AGAIN CALLED THE DEALER, HAD IT TOWED TO DEALER WHERE THEY TOLD ME THE THROTTLE BODY PIN CONNECTORS HAD TO BE SOLDERED ON WHICH THEY DID.

THE CAR HAS HAD SEVERAL DOCUMENTED ELECTRICAL AND MECHANICAL FAILURES. OVER THE PAST 2 YEARS THE CAR HAS BEEN SHUTTING DOWN AUTOMATICALLY IN THE MIDDLE OF TRAFFIC. THE DISPLAY SHOWS 'ENGINE POWER REDUCED' AND IS FOLLOWED BY OTHER MESSAGES LIKE 'SERVICE ANTI-LOCK BRAKE SYS' OR 'SERVICE RADAR' OR SERVICE STABILITY SYS AND TRACTION CONTROL.' BEFORE THE CAR SHUTS DOWN THE TRACTION CONTROL IS AUTOMATICALLY DISABLED. I HAVE HAD TO BRING THE CAR IN FOR THE SAME SYMPTOM 4 DIFFERENT TIMES. THE IN-SERVICE DATES THAT WERE DESCRIBED AND DOCUMENTED FOR THIS PROBLEM ARE AS FOLLOWS: 1.)FEBRUARY 22, 2008 ' 'POOR DRAG ON C102 CONNECTOR UNDER HOOD' 2.)APRIL 24, 2009 ' 'FAILED CONVERTER' 3.)OCTOBER 1, 2009 ' 'ECM FAILED' 4.)MAY 5, 2010 ' 'REPROGRAM PCM' ALL OF THE ABOVE WERE SERVICED BY CLASSIC CADILLAC SAAB. EACH TIME THEY FIX SOMETHING NEW BUT THE SAME SYMPTOM CONTINUES TO OCCUR. I AM EXTREMELY CONCERNED FOR MY FAMILY'S SAFETY WHEN TRAVELING IN THE CAR, ESPECIALLY WHEN IT HAS SHUTDOWN NUMEROUS TIMES BOTH ON A HIGHWAY AND IN THE MIDDLE OF AN INTERSECTION. THE CAR HAS BECOME A SEVERE LIABILITY FOR BOTH ME AND MY FAMILY. SOMETIME IN DECEMBER 2010 THE CAR HAD SHUTDOWN AGAIN AND THE ENGINE LIGHT HAS BEEN ON AND OFF SINCE THEN. *TR
