Engine Cooling System Problems of Cadillac CTS

The contact owns a 2004 Cadillac Cts. The contact was driving 10 mph when fluid began leaking from the vehicle abnormally and the vehicle stalled without warning. The vehicle was towed to the dealer where the dealer advised that the transmission coolant line fractured from the radiator. The dealer advised replacing the radiator assembly, coolant lines and refilling with automatic transmission fluid. The vehicle was repaired. The manufacturer was contacted and offered no assistance. The failure mileage was 90,400.

Engine oil leaks into the coolant system through the oil cooler located in under the intake manifold. The coolant will then turn into a thick substance which does not easily flow through the coolant system and the car engine will overheat. To correct the failure the oil cooler needs to be replaced as well as all rubber coolant lines and then the coolant system needs to be flushed to remove all contaminated coolant. Typical cost is around 4500 dollars for parts and labor. The mileage on my car was 121,000 when this happened but from reading on line many other people have had this same problem with mileage from 50,000 on up.

I've had numerous problems ever since I bought my 2003 Cadillac Cts. My engine starts smoking under the hood when I turn on my heater when it's cold outside. I replaced my brake lights several times. My windshield wiper module is broke. I had to get a new motor for my window because that broke. I had nothing but problems with this car and many other people have the same conditions as me. Why isn't it on recall ??? I mean we paid good money for it so we should get the same quality back !!! I know gm has to review our comments. They just don't care about there customers. Gm needs better customer service because there service sucks!!!! recall. . . . Recall. . . . Recall!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!.

Purchased 2005 Cadillac Cts may 30, 2005. At first new owner check up I complained of a knocking noise under the drivers front side. Coastal Cadillac in pawley island, SC could not hear anything wrong. Made another appointment June 16, 2005 as we took a trip and my husband heard the thumping. They finally located the problem, a broken front strut, which took 3 days to replace. At that time I voiced my concerns about this vehicle and asked for a new car. The answer was no. Now on sept 2, 2005 my "check coolant level" message came on. I now have a leak in the coolant reservoir. The car only had 2,789 miles at the time. I am not looking forward to calling the dealer about this problem and thought I could just purchase coolant and fill it. I thought that this should not be occurring in such a new vehicle.
