Engine Oil Leaking problems of the 2005 Cadillac Deville

Engine began to leak oil after 40000 miles. The company and dealership assured me this was normal. Longer I operated this car, more it began to leak. At first few drops, then later, 1-2 qts between oil changes. Today, it is worst. I have spent several thousand dollars related to this engine. The leaks continue to this date. Engine stopped once on me, shut off, nothing worked. No airbag, any electrical service. Hit hole in road and everything shut off. Called company many times, wrote to president, other executives all to no avail. There are many Cadillac Devilles with same leaking problem, the northstar engine has this problem since 1998, on all their models. It is like the key, they will do nothing until made to correct it. I hope you follow through, this is not right and cause many problems with deep expenses for owners.

Oil leak underneath engine has progressively gotten worse. Mechanic says it will cost $2,000. To fix. Two sections do not fit properly, so this model will leak oil.

This northstar engine has leaked oil,(not burning it) since 40,000 miles. I use 2 or more quarts of oil between oil changes. It leaks whenever it is parked. I have spent monies on this, but it appears a major engine repair is needed. Some say, the bolts were too short, and others say, this defect continued until the 2006 year.

Airbags failed to open after engine died. Car went dead and steering brakes failed to operate properly. Seat became unlocked. I was jammed under steering wheel. Engine and car dead. Front end and rear end total, never received replacement. Insurer was geico, repaired at their recommended facility. Engine began to leak oil after 20000 miles car never operated correctly afterwards, traded it in after 6 months, for 2005 new cts. Same thing happened, engine shut off,. I traded for 2005 Cadillac Deville, in 2005.
