Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Vehicle cuts off at random times while in motion. The car ignition cuts off all power to the engine and power steering when the car hits a bump, railroad track, or pothole. Bumping the column cover will also cut off the engine, and the power steering. The vehicle has had the key modification which would appear to have no affect on the problem of the ignition randomly rotating out of the on position.

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 Deville 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.

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.
