2002 Buick LeSabre Owner Comments

problem #2

LeSabre ES 3.8L V6

  • Automatic transmission
  • 125,000 miles


In a nutshell, the little part that is leaking coming off the engine and going to the fuel feed (supply) line has two working parts. A plastic part and O-rings. If the mechanic takes apart the little part that is leaking and can't fix it (with O-rings that must be the same size as the old AND be able to handle being in contact with fuel, or the little plastic part inside breaks or is broken) then that part itself isn't sold separately and the entire fuel rail will need to be replaced.

If that is what happens, then I am without wheels for 5 to 7 business days while the part is ordered AND it will cost upwards of $700.00 for parts and labor. Why the little part thingie isn't readily available as a separate part from the fuel fail is PART MALPRACTICE in my humble opinion. AND to add insult to injury, we won't even know if the o-rings and/or plastic thingie in that part can be fixed unless and until they take it apart. If not, then my car sits in their shop and I have to rent a car while waiting on parts. What a way to do business!

Meanwhile, I have gasoline leaking out onto a hot manifold. Not feeling very safe driving right now to say the least. Sorry, but even the mechanic didn't have a name for this part that is leaking. It is directly connected to the engine then connects to the fuel feed (supply) line to fuel rail. (That is what he wrote down on a piece of paper for me). If you were here I could point to it for ya but darned if I can find a picture of it online.

I found out that this gas line leakage issue exist in everyone that I know with this model vehicle. There is a fuel line clip that can be replaced. The clip is inserted at the end of the fuel line that connects to the engine but this clip doesn't last very long once replaced. Eventually the clip won't work anymore as if it is the fuel line itself that is bad. This issues seems to be a defect in this model Buick and is dangerous. I'm just wondering how can such an issue never been on the Buick recall list for this model car. Most people that have this car say that they have smelled the gas fumes and didn't know what it was. The gas actually leaks/ drip from the fuel line's clip onto the hot engine. (Can you say very dangerous) This is a lawsuit waiting to happen!
