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 noticed that the main frame of the vehicle was perforated due to severe rust corrosion. The vehicle was taken to an authorized dealer for inspection and they replaced the rusted fuel tank filler neck. The vehicle was taken back to the dealer on a separate occasion. The technician detected a rusted brake backing plate, and the front and rear brakes were replaced. In addition, four new tires were mounted on the vehicle. The technician was unable to perform a tire alignment due to the significant frame damage. The VIN was unable to be entered into the system. The failure mileage was unknown and the current mileage was 62,000.

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.

Fuel tank filler was giving as the reason of my trucks problem before it was looked at by a technician. I was told that this was a common problem with these trucks. The fault would cause the emissions system to fail and therefore would also be a hazard because it could cause a fire at the time the truck was being filled or from escaping vapors. The part was (is) being replaced and is costly to the consumer.

Tundra 4WD 8-cyl

  • Automatic transmission
  • 37,000 miles
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 Tundra. 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.
