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.

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 halves are leaking and I was told to fix 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.

The contact owns a 2001 Cadillac Deville. The key would turn, but the vehicle would start intermittently. There were no warning indicators present. The dealer stated that the key needed to be replaced and the failure continued after the repair was made. While driving between 5-35 mph, the vehicle stalled. The service engine warning indicator light illuminated and there was a loss of power brakes and steering. The gear was shifted into neutral and the vehicle restarted. The dealer made repairs, but the type of repairs were unknown. The failure persists. The failure mileage was 88,000 and current mileage was 94,000.

Service engine light comes on and vehicle engine will unexpectedly die leaving you with no power assist on brakes or steering, a very dangerous situation. Dealer has replaced engine crankshaft sensor the third time now. The engine died unexpectedly numerous times, and the engine crankshaft sensor has been replaced three times in 52,000 miles. Dealer says Cadillac will not pay for replacement even though they are aware of the problem and sensor had been replaced twice previously. We are extremely lucky these incidents did not cause a major crash.

2001 Cadillac Deville. Intermittently won't start. All lights in car come on, so there is electrical power. I have been having this problem for 2 years...I am now on my 3rd dealer/service. Problem never shows up on diagnostics...they have been able to duplicate a few times....still unable to fix. PCM has been replaced 2 times. I am very frustrated....please help....the service departments also do not know what to do...

During routine service the mechanic discovered that the mid engine gasket was leaking. This is a 2001 Deville with the northstar engine and only 48,000 miles on the odometer. I have done some research and know that this is an ongoing issue with that engine. I was also informed that it could cause a fire. In order to correct this, I must pay the dealer $2,000 as they have to tear the whole front end of the car apart to get to the problem area. This is an issue which should encourage a recall.

: the contact stated while navigating slowly through a parking lot the vehicle lost power. After multiple attempts the vehicle was restarted. When the vehicle was restarted the battery warning light came on and went back. The vehicle was driven directly to the dealership. They were unable to identify the cause of the problem through the vehicle's built in diagnostic system.

2001 Cadillac Deville. The consumer states the vehicle will die suddenly. The vehicle will start up after this happens without having to wait. This happened three times, and it started right after purchase of vehicle on May 30, 2002. The vehicle was towed to the dealership three times. The consumer did not feel safe driving the vehicle. They kept changing the crank shaft position sensor. The vehicle was towed the second time May 28, 2004, and the third time, March 28, 2005. The speed does not matter when this occurs.

Excessive oil consumption, 1 quart of oil every 800 miles. Cadillac appears to be well aware that this problem exists with some North star engines, (based on specific oil consumption procedures dictated to their dealerships, I.e.ring flushing, ring replacement with special rings, etc), but fails to inform the consumer of this potential problem when purchasing a new vehicle.

My 2001 Cadillac Deville uses 2 quarts of oil ever 1300 miles. This is excessive oil consumption for a vehicle under 50,000. I have reported this to GM and my local dealer. They say that this is normal. I reported this over a year ago! I was having a oil consumption test, but now they can not find the records.
