I bought a 2007 Toyota Tundra less than 3 months ago from Toyota of Simi Valley. 2 months ago my check engine light and other warning lights suddenly went on while I was driving and my truck went into “limp mode” while merging onto a freeway, causing other drivers to swerve around me to avoid a collision. I took the truck back to Toyota and they advised the Air injection pump and air control valve need to be replaced. Total cost to repair is almost $4,000. I purchased at Bronze level extended warranty which covers up to 24,000 miles but the insurance carrier denied the claim saying these items are excluded, despite these items not being listed on their “excluded items list”. Toyota then offered to pay 1/2 the total cost of repairs, which in of itself is an admission of guilt. I’ve only made 2 payments on the vehicle, I should not be responsible for these repairs. I took the vehicle to an independent mechanic who advised Toyota’s assessment is correct, however, it should only cost $2k to fix the vehicle, not $4k. The mechanic also advised of an emission system issue and that this vehicle will not pass smog at this time.

After filling the gas tank and driving home, I happened to notice something hanging down under the driver’s side of the truck. The rear of the two fuel tank bands was fractured near the outboard mount and appears to be due to excessive corrosion. I have no idea if it separated that day or how long I may have been driving with just the front fuel tank band (also rusted) holding the fuel tank in the vehicle. If I hadn’t had a clear view of the truck from a distance (from sidewalk a few houses away), I’m afraid I might never have noticed until the front fuel tank band (now under greater loading condition) also fractured. I’m assuming in that scenario, the fuel tank would drag the ground, held only by the fuel lines, with possible deadly consequences depending on vehicle speed and other factors. I can’t stop my mind thinking about what might have happened. At higher speed, would the rear axle have catapulted over the fuel tank causing loss of control, even before any fuel leakage?

Suddenly, I discovered that my fuel tank showing as if it's about to drop on the ground. As I inspected, the fuel tank rear strap broke off the frame due to corrosion. the strap itself was not the issue, part of the corroded frame was still attached to the strap. When I took the truck to my local Mechanic, further inspection showed worse signs of corrosion in the entire frame and in every part connected to the frame as well; suspension parts, brake parts, emergency brake parts, spare tire hinge; etc. Against my disagreement with Toyota dealership, I had the truck painted by Toyota as they recommended during the frame recall in February of 2018. I wanted to replace the frame, based on other professionals advice, but Toyota Dealership insisted that my truck frame is in good shape it ONLY needs the paint recommended by Toyota. I come to find out that they have not remove nor clean any rust and they painted on top of it. Additionally, They never painted the cross members above the tank Now, when I looked under the truck, the paint has coming off in greater areas of the frame showing heavy rust under it. Which means the paint job was a joke, and worthless. Now, after seeing this, I am wondering how can I possibly drive this truck. The tank can drop any time or the spare tire latch can break off, causing a disaster on a highways where I drive. My emergency brake not even adjustable any more due to the heavy rust caused by the frame. Toyota failed to engineer the frame, and later on, failed again to correct their own mistake. contacted the dealer and waited for a month, no response. I called Toyota headquarter and filed a complaint. They respond is that because the recall program has expired there is no further assistance from Toyota. My question to Toyota is, are they going to wait to hear a disaster on one of the highways caused by their faulty equipment and workmanship, or will they take action before it happen. Attached are some pictures.

Rear fuel tank strap bracket detached from frame. Bracket appears to have corroded and detached at its frame weld without warning. Tank dropped about 3 inches down at rear and was barely supported by the front tank support strap and the flexible fill hose, which appeared to prevent it from shifting. The fill hose is attached to the tank via a stainless steel clamp. The tank could have dropped from vehicle when I was on the highway, before I was even aware of the issue. I happened to see something sagging when I was walking to my vehicle. It appears that the tank bracket would be very difficult to inspect, and I believe I had the vehicle inspected for a corrosion recall about 2-3 years ago. I was lucky I observed the tank when I did, it may have broken 1 or 2 days before I even noticed it. Attached photo shows the corroded detached bracket assembly. I was able to temporarily resupport the tank under the existing strap.

My gas tank strap rotted off my frame causing my full gas tank to almost fall out. My frame rotted very bad also. I know there were recalls concerning this issue but I'm not sure if they were done to mine. I've only had the truck for three months what do I do?
