CarComplaints.com Notes: A dependable pickup option that does have a slight history of frame corrosion. Even though mud looks cool on a truck, it's best if you run this through the car wash every now and again.

The contact owns a 2003 Toyota Tundra. The contact stated while driving at 30 MPH, the brake pedal was depressed several times but failed to respond and went all the way to the floorboard. The contact's son intentionally hit a curb and downshifted in order to stop the vehicle. The vehicle was towed to an independent mechanic where it was diagnosed that the subframe was severely corroded and an unknown axle was leaking and causing the brake failure. Additionally, the independent mechanic diagnosed that the gas tank was detaching from the vehicle due to the frame corrosion. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was approximately 146,000.

As I was traveling at a slow speed when I became aware of a loud grinding noise which had suddenly began as I turned onto a side street. I stopped vehicle immediately and got out to investigate what was causing the noise. I discovered that my fuel tank was dragging beneath the truck. The metal straps that held tank to frame had rusted thru causing tank to fall to road surface. All the connections to fuel tank were ripped from tank. Toyota is worried about the spare tire falling down do to rusted frame members but I feel they should be more worried about their fuel tanks falling off. If I had been traveling at highway speeds I hate to think of what consequences might have been.

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.

I received the ssc 90M - Tundra vehicles severe corrosion of the rear cross member phase 2 - crc application. My truck has a tonneau cover and a bed rug installed. When I called the dealership to schedule an appointment they informed me that the bed of the truck would have to be removed to complete the repairs. I told them that I did not have the means to remove the tonneau cover and the bed rug. They said that they could not perform the repair without these items removed and that they would not remove them for me. I then contacted Toyota customer experience center at 800-331-4331, extension [xxx] and discussed the situation with [xxx]. she claimed that the recall letter states that the truck must be presented in "factory condition" (I guess that means no bed rug or tonneau cover). I reread the letter and that is not stated anywhere in the letter. I called her back and she was unable to assist me nor would she elevate my issue to the management level. This recall work must be done, and again, I have no means to remove these items. I'm sure that I'm not the only Tundra owner experiencing this issue. This truck will be unsafe to drive if the recall work is not done. Please help. Thank you. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Engine check light on due to small leak in evaporation control. Toyota dealer inspection determined leaking filler tube. Cost to replace $350+. how many of these complaints are necessary before this is recognized as a defect?

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.

TL-the contact owns a 2003 Toyota Tundra. The contact began to smell gasoline inside the vehicle. The vehicle was taken to an authorized dealer where they were unable to diagnose the failure. The failure continued so the vehicle was taken back to the authorized dealer where a leak was found along the welding within the fuel tank. The fuel tank was replaced. The failure mileage was 52,754 and the current mileage was 54,754. Sm.

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.
