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.

problem #1

Park Avenue 3.8L V6

  • Automatic transmission
  • 97,500 miles


Around 97,000 miles I kept getting a "engine coolant low" light come on. At first I thought it was not a big deal and just added some coolant to my reservoir. After a 2 weeks the light came on again, and I checked and my reservoir was empty again. So I added a little more, and sure enough 2 weeks later my car had gone through about a gallon of coolant, but with no visible leaks. I finally checked my oil and found a nice mixture of coolant and oil. I did some research and found this was a common problem because GM used crappy gaskets which erode over time causing coolant and oil to mix. To fix requires the upper and lower intake manifold gaskets to be replaced.
