For almost 9 months, I have not been able to fuel my 2004 Toyota Corolla without the gas pump stopping despite my gas tank not being completely full. This occurs on a weekly basis. I have been told the cause for this is a faulty charcoal canister. This may not necessarily be the correct diagnosis; instead there may be something wrong with the ventilation in my gas tank that is not allowing fumes to properly ventilate while fueling the vehicle. I have had no repairs to address this problem because the cost of a new charcoal canister ($400) is quite high and the charcoal canister may not even be the problem. I would like to see if any other 2004 Toyota Corollas have had this issue as well.

I have a 2004 Toyota Corolla. The 'check engine' light came on last week. I took the car to the dealer who said the car needed a new filler neck and gas cap. The dealer said this is a common problem in this make/model car. I checked the internet and found that other people did have the same problems. I don't think it's a big safety issue, however, I would like to ask why a recall hasn't been done and how to possibly go about initiating that process. Thank you for input on this...janet braatz updated 09/25/09

At first I noticed the gas tank would not fill properly. I thought it was not venting properly, but I had a technician check it over. Eventually, they replaced the fuel fill gauge (to no avail, might I add). The problem persisted, and I had the car checked again. Finally, they discovered that there was a problem with the charcoal filter. Unfortunately, I reported the incident before my warranty was up, but the dealer's service station did not get a chance to look at it until afterwards. All in all, between service and parts, this has cost me about $500. The old parts are not available, and I will see tomorrow morning if this charcoal filter malfunction is really the problem. I imagine it is, since I have seen multiple complaints about them on the newer Corollas.
