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.

We have a 1998 Cadillac sts and are running into problems with it running hot. After replacing the radiator, thermostat and coolant, there is still the same problem. It will only be after the engine is warmed from driving will this occur, it will start to run hot if you give the vehicle gas to try and get into traffic flow. We have consulted quite a few machanics on this problem and they have all given us the same explanation for the presumed problem. Especially one that use to work directly for Cadillac as a mechanic, they state there is a problem with the steel bolts in the aluminum engine and if there is any type of sudden exceleration then the engine will run hot or overheat. This is a known common problem stated by any mechanic that knows about this type vehicle, especially when they are telling us this happens all the time to Cadillac. We have not replaced anything yet but have been advised this would be a very expensive job to do, and we were advised the problem will get so bad in the near future the repairs will have to be performed to even drive the vehicle.

Car was serviced 2 weeks prior for sluggish performance and huge oil consumption. Car in for service again! now for blown head gasket problem. This Cadillac has too many dealer/manufacturer problems. Dealer should pay for these problems. Not customer. VIN [xxx] check service history. Unbelievable! updated 07/25/2012 information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6)
