I took my 2001 GS430 in for 90k service last week. After receiving it back, I was unable to put fuel in it without the gas station pump shutting off after less than half gallon. I have to repetitively to this to get any gas in it. I could hear the hissing sound of air pressure being released if I pulled the nozzle out after the shut off occurred. I took the car back and the dealer charged me $550 to replace the filler neck which they said has a pressure release valve that was probably the culprit. It didn't fix the problem. They have the car back and can't seem to locate what is wrong. They are waiting on a call back from Lexus support.

Any ideas on this? It is a very annoying problem. Yes, I tried several different pumps at several different gas stations just to make sure.

Thanks!

Holy cow $550 for the filler tube. I need to open my own dealership. Anyways, the tube for the EVAP system probably got kinked or is somehow clogged.

What he said. Usually that filler neck deal is usually a recirc unit. The EVAP system usually has a diaphragm to let the fuel vapors out and usually catch in a charcoal canister to prevent "venting" harmful HC to the environment. But since its a pressurized system you can try to put gas in but if there is air still displaced in there it wont fill like what you are experiencing.

I have similar problems with my GS4. I usually pull the nozzle out of the fill tube a little bit and change the angle of entry so that the spout is angled more upward. That seems to help quite a bit.

I have the same exact problem on my GS430, I too put the nozzle out a bit and at a angle, or it keeps shutting off. I have had this problem for a while now.

i've had a similar problem too on my 01' 430...1 out of 5 gas stations i can't get it to work at all...the others i have to adjust the entry depth and angle to get it to work....i think i can live w/ it though if it's $550 to fix! hopefully it doesn't get worse

When this happened to my 2K1 GS430 it was diagnosed as a stuck check valve. There is a check valve at the bottom of the filler, not sure whether it is in the tank or not, but it was stuck. Some piece of sticky paper had adhered to it and it was stuck. I wrote it off to maybe carelessness with a gas additive but it happened again to my car a couple of months later and my wife's 2k3 GS3. It wasn't any $550 but it was the better part of $200 each time as I recall for Lexus to take it out and clean it. We both used the same gas station and have quit using it. Problem has not returned. I have also gotten very thorough looking at the filler nozzle to make sure somebody hasn't left a present for me on the end from their use of some gas additive.
