Crankcase (pcv) Problems of Cadillac Deville

2003 Cadillac Deville. Consumer writes in regards to several mechanical defect issues. Consumer sent additional correspondence. The consumer stated the water pump and radiator leaked resulting in a coolant leak, and the engine overheating. An independent mechanic determined the metal brackets holding the left side tank had rusted and caused a crack in the left radiator tank. The engine developed an oil leak from the lower crankcase of the engine block. The oil leak caused a defective design in the lower crank shaft. The mechanic informed the consumer the engine needed to be removed to properly repair the oil leak. Also, the tire pressure light illuminated.

I have a 2001 Cadillac Deville with a 4. 6(y) motor while I love the car the motor is the pits it is very costly using over 1qt between oil changes and now I have a misfire and lost of coolant and was told that my head gasket had blown and my crankcase halfs are leaking and I was told to fix it it would be a new engine at the cost of $8k so I guess I will have to deal with the random misfire because I cant afford to fix it you would think since Cadillac is gm's luxury brand they wouldn't have the customers deal with this sloppy engine also I have had the oil drip on the exhaust and start a small fire so now I will have to try and baby this thing.

My husband and I purchased a 2002 Cadillac Deville October 14, 2001. On April 25, 2003 with 11,059 miles on the odometer the car stalled while driving and we were able to pull over to the curb to allow the traffic to go by. We were able to restart the car and proceed to the dealership where they replaced two sensors under the warranty. On July 28, 2006 with 30,779 miles on the odometer it stalled again at a traffic signal. After trying for sometime the car was restarted and we took it to the dealer where they replaced these same two sensors at a cost of $468. 65 to us. I am 82 and my husband is 85 and we feel this is a dangerous situation to be driving and have the car stall in heavy traffic with perhaps an accident as a result. We are almost afraid to drive the car not knowing if this will happen again, especially on a freeway. Our son told us of a friend's father who had this same thing happen to him three times on his Cadillac like ours. We wonder if this is a defect that should be looked at on all of this model and year of Cadillac.

: the contact stated the engine light illuminated and the vehicle was difficult to start. An independent mechanic put the vehicle on a diagnostic testing machine and determined the vehicle needed crank shaft position sensors. The Cadillac dealer agreed there was a problem with the sensors and informed the contact the sensors were being replaced with upgraded sensors.

While driving and without warning the engine died. It started right up again. Called dealer, and they knew about the problem. Caller made appointment with dealer to fix the problem. Crank shaft sensor needed to be replaced at owner's expense.
