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.

As others have reported here, and on other forums, the oils consumption was remarkably high. I always tolerated it, because otherwise I loved this car. I vas very fastidious about keeping the oil level at an acceptable point. During cold weather in March of 2011, It went from near perfect performance to a very rough idle, and a host of P codes. Close inspection revealed that the plenum had cracked, and was causing a major vacuum leak. The mechanic at the Cadillac dealership near my home revealed that it was a very common problem with that motor.
