The gauges in the instrument panel stop working. The speedometer has stopped working I am driving a vehicle and not know how fast I am driving. The gas gauge has stop working I don't know how much gas is in my car I have to fill the tank and check it every two weeks so I will not run out of gas.
The fuel gauge indicates properly until it reaches the halfway mark. It then fluctuates and is not reliable. This could lead to running out of fuel in traffic, in-climate conditions or in isolated areas without indication. This is a safety hazard that seems to be prevalent on these vehicles and needs to be addressed!
Car windows and gas gauge haven't worked in a long time however now the car will not start consistently even with a brand new battery. You have to charge the battery every time to start it. Ready to get rid of this worry.

While driving home my fuel gauge stopped working. When I got home I turned the car off and then back on and the fuel gauge was now in the 6 position on a clock. Now I have no idea if there is any fuel in the car or not. Luckily I reset the trip meter with every fuel up so I know I can go approximately 300 miles. Although in the winter when we have to idle our car so the fuel mileage goes down and I do not get as many miles on a tank. Hope I don't run out of fuel during the winter. In reading online reviews about this issue it turns out it can get worse and cause the speedometer to stop working. Then I may be speeding and not even know it. I did try and have it fixed but the guy charged me $207 and it did not fix the problem. At the local gm dealership they said they would repair it for $350.

Fuel system, gasoline: delivery
- What is wrong
- On certain passenger vehicles equipped with 3800 v6 (l36) engines and certain delphi fuel pressure regulators, the regulators have a much higher than usual rate of fuel leaks. A leak can allow fuel to enter the intake manifold through a vacuum line. If the engine does not start when cranked, the fuel from the leaking regulator and a mistimed spark can cause a backfire.
- Risk
- The backfire can rupture the intake manifold. The rupture of the intake manifold can displace a fuel line, pulling an injector out of place, and causing a fuel leak and possible fire.
- Remedy
- Dealers will install new fuel pressure regulators with improved diaphragms. The recall will be conducted in phased mailings. Phase 1 began on june 30, 2004, and phase 2 began on september 30, 2004. Owners should contact buick at 1‑866‑608‑8080, oldsmobile at 1‑800‑630‑6537, or pontiac at 1‑800‑620‑7668.
