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.

2003 Buick Regal Owner Comments

problem #1

Jul 202011

Regal 3.8L

  • Automatic transmission
  • 160,000 miles


This is a common problem on most GM vehicles made in the 2000's, possibly the 90's, and should almost be considered planned maintenance because it WILL HAPPEN. Your car will take a while to start, either all of a sudden, or progressively longer over time depending on how quickly your FUEL PRESSURE REGULATOR is failing. What happens is a little rubbery diaphragm inside of the pressure regulator that moves back and forth all of its life gets a hole or a tear in it, either from fuel choice or simply wearing out. This causes incorrect fuel deliver during start up, but once the juices are flowing the car may smooth out and run perfectly in most cases. It is worth looking into if anyone ever tells you your fuel pump is going out because this part only costs about $50 on a bad day. Typical life expectancy for this part is a little over 100,000 miles. Mine made it for 160,000. Some go sooner as well.
