2005 CADILLAC CTS Power Train Problems

Transmission cooler line fittings have dissimilar metals causing the threads inside the radiator transcooler to strip and dump coolant into Transmission lines and on road along with what was the transmission fluid as well as steam rolling out blocking vision through my windshield going uphill on a dangerously busy road crossing.This is a well known manufacturing defect that has yet to be handled. This could have gotten me and my 3 year old son seriously hurt by sudden loss of power and slick roadways not being able to avoid or brake properly or even steer away from on coming collision. The dissimilar metals are aluminum nut with a mild steel washer backed by a stainless steel washer before it contacts the radiator. This car has 101k miles and has been babied it's entire life. And when I see the 4 brake lines are about to rust out after all the...

THE VEHICLE IS EQUIPPED WITH A VERY WEAK REAR DIFFERENTIAL THAT WAS USED IN THE LESSER HORSEPOWER V6 AND WHEN TAKING OFF HARD THE CAR BEGINS TO WHEEL HOP AND DESTROYS THE REAR END THE VEHICLE WAS IN MOTION ON A CITY STREET THIS HAS OCCURRED TWICE IN LESS THEN A YEAR AND A HALF

THERE'S A VERY HARD JERKING COMING FROM SOME WHERE IN THE REAR AREA WHILE DRIVING. WHEN THIS HAPPENS THERE IS A LOST OF POWER. ALSO THE ENGINE OIL IS GOING SOME WHERE ,I KEEP HAVING TO PUT OIL IN IT , ABOUT TWO TO THREE QUARTS A WEEK. WHEN THE OIL GETS REAL LOW THE ENGINE SHAKES AND RUNS LIKE CRAP AND ACTS LIKE IT WANTS TO CUT OFF.

VEHICLE DEALER REFUSED TO PERFORM OPEN RECALLS. I REPLACED FRONT BRAKE HOSES MYSELF AT MY OWN COST. THEY STATED VERY HIGH MILEAGE 184000 MILES AND YOU DID NOT BUY THE CAR HERE.

IN A PANIC AS I AS COASTING I WAS FORTUNE ENOUGH TO WEAVE MY WAY ACROSS 2 LANES TO THE SIDE OF THE HIGHWAY AND ROLL TO A COMPLETE START. AFTER GATHERING MYSELF I TURNED THE IGNITION FROM THE RUN POSITION TO OFF. I LOOKED UP AND NOTICED THERE WAS SMOKE COMING OUT FROM UNDER THE HOOD. I JUMPED OUT, LIFTED THE HOOD, AND HEARD POPPING AND STEAM/SMOKE RISING UP FROM UNDERNEATH THE ENGINE BY THE FIREWALL. I PULLED THE OIL DIPSTICK AND I WAS ABOUT A QUART LOW, AND IT LOOKED NORMAL.

I HAVE A 2005 CADILLAC CTS WITH 67,000 MILES. SINCE ABOUT 65,000 MILES CAR HAS BEEN MAKING A RATTLING SOUND UNDER THE HOOD DURING ACCELERATION.

ONCE MY CAR HAS ACCELERATED AND THE GEARS HAVE CHANGED (I.E, SECOND GEAR) THE RATTLING SOUNDS STOPS..THE NOISE IS CONTINUOUS AND ONLY HAPPENS AT ACCELERATION, NOT WHILE IDLING. IN ADDITION EVERY NOW AND AGAIN WHEN A FRONT SEAT PASSENGER GETS IN THE CAR THE AIRBAG SENSOR/LIGHT COMES ON THE DASHBOARD. THIS PROBLEM DOESN'T HAPPEN OFTEN BUT IT HAPPENS EVERY ONCE IN A WHILE. UPON DOING MY RESEARCH FOR BOTH THESE ISSUES I FIND THAT I AM NOT THE ONLY ONE HAVING THIS PROBLEM...HOPEFULLY SOMETHING WILL BE DONE SO THAT GM CAN ADDRESS THESE SERIOUS ISSUES WITHOUT HAVING THE CONSUMER/OWNERS HAVING TO PAY AN ARM AND A...

I JUST BOUGHT THE CAR ON DECEMBER 18TH, 2009 FROM A SMALL DEALER. IT SNOWED OVER THE WEEKEND IN DELAWARE. I HAVE BEEN NOTICING A LOUD NOISE COMING FROM THE REAR AXLES AS I WOULD TRY TO NAVIGATE THROUGH THE SNOW. IT SOUNDS LIKE THE REAR IS HOPPING UP AND DOWN RADICALLY.

AFTER A ROAD TEST AND INSPECTION, THE DEALER DETERMINED THAT THE PROBLEM WAS THE REAR DIFFERENTIAL, AND IT WOULD NEED TO BE REPLACED AT A COST OF ABOUT $1700.00. I'VE OWNED MANY USED CARS OVER THE PAST 30 YEARS, SOME WITH OVER 100,000 MILES ON THEM, AND I'VE NEVER, NEVER NEEDED A NEW REAR DIFFERENTIAL ON ANY VEHICLE THAT I'VE EVER OWNED!
