I HAVE A 1999 CADILLAC DEVILLE, THERE IS A PROBLEM WITH THE REAR SUSPENSION KNUCKLE ASSEMBLY, I HAVE HAD THIS CAR TO 2 DIFFERENT DEALERS, THE SECOND DEALER, LAST SUMMER, REPLACED THE REAR STRUTS & STABILIZER BAR WHICH DID NOT RECTIFY THE SITUATION WHEN AMBIENT TEMPERATURES ARE ABOVE 60 DEGREES, I HEAR A "FIERCE" SCREECH/SCRUNCH SOUND FROM THE REAR SUSPENSION, I HAVE GONE ROUND & ROUND WITH CADILLAC CUSTOMER SERVICE & THE DEALERS, NOW THAT THE CAR IS NO LONGER UNDER WARRANTY CADILLAC DOESN'T WANT ANYTHING TO DO WITH IT. I HAD MY OIL CHANGED & THE TIRES ROTATED LAST WEEK & WHILE THEY WERE UNDER THE CAR I HAD THEM TO LOOK AT THE REAR SUSPENSION, THEY SAID IT NEEDED A NEW KNUCKLE ASSEMBLY & THE DEALER KNEW BETTER THAN REPLACE REAR STRUTS WITH THIS TYPE OF NOISE. IT SEEMS THAT NOURSE CADILLAC IN DELAWARE RAN UP A BIG TAB & BILLED IT TO CADILLAC (WARRANTY) AND AS SOON AS THEY MADE THEIR MONEY THEY WANTED NOTHING MORE TO DO WITH THE CAR SO NOW I AM STUCK. A CAR OF THIS MAGNITUDE & PRICE SHOULD NOT HAVE REAR COMPONENTS WEARING LIKE THIS, I ONLY HAVE 77,000 MILES ON THE CAR & I DO NOT DRIVE IT HARD....WHAT DO I DO?*AK

FIRST TIME ENGINE FAILED WHILE DRIVING ON INTERSTATE AT APPROX 75 MPH. ENGINE COMPLETELY SHUT DOWN WHILE PASSING SEMI. ALL LIGHTS ON DASH CAME ON AND TOTAL LOSS OF POWER STEERING. AFTER SERIOUS SCRAMBLING TO GET CAR OFF ROAD AND BRING TO SAFE STOP ATTEMPT TO RESTART WAS SUCCESSFUL AND TRIP OF 600 MILES CONTINUED W/O INCIDENT. FIVE DAYS LATER SAME THING OCCURRED ON SUBURBAN STREET IN HEAVY TRAFFIC AT APPROX 45 MPH CAUSING A LOT OF CONSTERNATION BY DRIVERS BEHIND ME THAT DID NOT UNDERSTAND WHY I CAME TO SUDDEN DECELERATION. TOOK CAR TO CADILLAC DEALER AND THEY FOUND NO PROBLEM. THEY CHARGED ME $112.50 FOR ENGINE DRIVEABILITY AND PERFORMANCE DIAGNOSIS AND DID REPLACE A DEFECTIVE EGR VALVE WHICH I FEEL HAD ABSOLUTELY NO ASSOC W/ STALLING PROBLEM. I THINK AFTER LOOKING AT ALL THE OTHER FILINGS OF THIS PROBLEM IN THE NHTSA RECORDS, THAT CADILLAC HAS A REAL PROBLEM AND HAD BETTER GET ON IT BEFORE SOMEONE GETS KILLED. DT

VEHICLE DESCRIPTION: PASSENGER VEHICLES. SOME OF THE SIDE IMPACT SENSOR MODULES HAVE QUALITY PROBLEMS THAT CAN CAUSE AN INADVERTENT DEPLOYMENT OF THE DRIVER OR PASSENGER SIDE IMPACT AIR BAGS. THESE SIDE AIR BAGS DEPLOY WITH LESS FORCE THAN A FRONTAL AIR BAG AND ARE DESIGNED TO MINIMIZE THE RISK OF SERIOUS INJURY.
Consequence & remedy
Consequence: HOWEVER, AN OCCUPANT CAN RECEIVE SOME INJURY FROM A DEPLOYMENT.
Remedy: DEALERS WILL REPLACE THE DRIVER AND PASSENGER SIDE IMPACT SENSING MODULES. IF THE VEHICLE HAS HAD THE SIDE AIR BAGS TEMPORARILY DISCONECTED, THE TEMPORARY DISCONNECT WILL BE REMOVED BEFORE REPLACING THE SIDE IMPACT SENSING MODULES.
