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.

1999 Cadillac DeVille Owner Comments

problem #1

Oct 192015

DeVille Sedan V8, 4.6L Litre

  • Automatic transmission
  • 105,350 miles


First time it ever happened was on morning of 10/19/2015. Got into car. Buckled up seat belt. Turned on ignition, heard the warning beep. Thought it was the headlight switch may have been left on. Checked and it was off. Looked at dashboard and looked normal except the seat belt warning light was still on (Usually turns off after 6 beeps unless I haven't buckled it up.).

I turned off car. Unbuckled myself, then turned on ignition, the beeping and warning light still happened. I turned off car, then buckled up fully, then turned car back on. Same thing happened. Seat belt warning light came on, never went away, kept beeping for about a few minutes while I drove. Tested this 3 times with same results during today. Found no issue or help online as of yet.
