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.

Auto now has 7,000 miles and runs fine except for oil leaks which no one wants to bother with. I will be contacting GM, BBB, and all others to get a satisfactory answer to fix this problem. Bought this car about a year ago and I think the dealer knew the problem and waited until a oil change service a year later to report the oil leaks. Hope the electric cars take over. Why doesn't someone revitalize the Lear Steam Car. Have a good Day.

I have a 1999 Cadillac DeVille I notice after a normal routine oil change and before the next change is do I would have to add 1 quart of oil because the "Check oil Level" light comes on. I'm only driven the car limited miles and not happy with added extra oil. Is there a problem with my car before I take it to the dealership. Where I get the oil changed done I notice they are adding 7 1/2 qrts of oil everytime...Help please.....

This car is recently out of the five year warranty. It only has 41000 miles. It burns oil (2 qts/3000 miles) and dealer reports it will get worse. Dealer is aware this is a general problem with this engine. I plan to persue cost to repair with GM.

Car is using a lot of oil, more than a quart per 1000 miles. It is still in warrenty but runs out 12/08/03. Dealer is running an oil consumption test but I have found out that they know there are problems with this engine.
