I was driving down the road when the 'check engine' light came on. I took it to the dealer to see what the issue was and they stated it was a leak in the gas cap and that I didn't have cap tight enough. On the way home from the dealer the 'check engine' light came back on, so I took it back to the dealer. They stated that the fuel filler neck needed to be replaced and it's not covered under warranty.

Frame and rear end banjo housing rotted to the point where gear oil from rear end leaked out onto the road. Had to have vehicle towed to garage to make temporary repairs. In addition, frame is disintegrated with pieces falling to the ground. Taken to an independent garage and was told to take truck to toyota and both the rear end assembly and frame should be replaced. Garage, stewart's of georgetown, ma., states metal of frame has deteriorated to the point where you could poke holes in it with a screw driver. Frame examined on august 6, 2011 after pieces of frame found under the truck after labor day weekend. Truck has 40,700 miles on the odometer and used to deliver and pick up supplies for property owned. The consumer to date, he has been unable to locate a usable rear end assembly.

Check engine light came on and dealer advised the fuel filler tube had to be replaced for several hundred dollars. This seems to happen in most 2003 tundra according to research. Because truck has 136,000 miles, dealer refused to provide any help with cost of labor or parts. Dealer did acknowledge this has been a problem for 2003 models. So much for toyota dependability.

Check engine light always on giving gas codes. After extensive research this is a common problem with 2003 toyota tundras. Mine has been on my truck for 3 years since I bought it, and I constantly need to get it reset, until I decide to pay to get it fixed.

My 2003 toyota tundra had a check engine light come on. Diagnostic codes pointed to the fuel filler tube and air pressure tests by my personal mechanic (not a toyota dealership) proved that there was a crack in the fuel filler line. The mechanic states that they see this happening in many toyota's they work on. They suggested mentioning this to toyota directly, so when I go in for my other recall (severe corrosion of the rear cross-member) I am going to bring the original fuel filler tube that I had to replace for $300. I also see complaints being filed from other tundra owners about this same issue happening to them.

There is a flawed design of the fuel filler neck causing the check engine light to come on. Service advisor stated that it was a known problem but because my warranty was out, they would not cover the repair which ended up costing me $462.32. My mileage is only 14,500.

I took my 2003 toyota tundra in to toyota motors, guam because I had a check engine light. Toyota then sent a message to my vehicle service contract, warrantech automotive inc and they said that the fuel filler neck hose assembly was not covered. Reading information on the internet indicates that this is a common problem with the 2003 toyota tundra due to a "out of round" gas filler tube. There should be a recall on this part. Please assist consumers like myself for toyota motors to investigate this defect with the 2003 toyota tundra. The word needs to get out.

There is a flawed design of the fuel filler tube causing an intermittent check engine light. This is a known problem that toyota has with its 2003-2004 tundras. The problem affects fuel vapor emissions from the gas tank. They offer no support once one is out of warranty even though they are aware of their faulty design/build of this part.
