The contact owns a 2008 Toyota Tundra. The contact stated that while driving at an undisclosed speed, the fuel tank strap frame mount fractured. The failure was caused by corrosion. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 79,000.
Standard Vehicle Components failed. My 2008 Tundra [VIN [redacted] ] was inspected in Nov 2017 under HOF/WEP, passed with CRC applied, but now has a 2-finger-wide perforation in the frame and rusted through the gas tank support-a clear safety defect in a salt state like Maryland. The undercoating failed prematurely; I need goodwill frame replacement or buyback per the $3.4B settlement's spirit." (reference the 2017 class action, case no. 3:14-cv-03538). Toyota Brand Engagement Center has refused my request for repair or replacement or buy back. They also refused to provide written refusal. They admitted to recording the conversation, but refused my request for a copy or to record the call myself. There is literally no rust on any other portion of my truck as it is garage kept.
Took my truck in for maintenance and a bracket was hanging down. Dealer brought me back and showed me corrosion of mid framing and that gas bracket had rotted off. gave me a proposal of over $7000 to repair. I had said to them that I had the frame frame coated during the recall, and why weren't the cross members sprayed at that time. They replied Toyota said it was not needed. Did some research yesterday and found that rusting cross members was a problem, and that tire holders, and gas brackets were a problem. Called Toyota and they explained to me that certain vin #'s were covered but that mine was not. I asked them why my truck with the same issues was not covered? Was told corporate policy. Do I have any rights in this issue. My cell # is [redacted]1, my e-mail is [redacted]
I was washing my truck October,1,2023 and while spraying the underside with water I noticed the fuel tank hanging extremely low from the back while further inspection I observed the rear fuel tank strap had rusted off and the tank was hanging by the front strap which is very corroded along with all inner structure and frame rails which is rusted corroded and completely rotted out. This truck has been very well maintained and has only 104354 miles on it.
The air injection pumps went out. Vehicle could not get out of limp mode, was very dangerous as I couldnt get up to speed while merging onto traffic. Had to put hazards on and drive vehicle home under 25mph. Vehicles were going around me. Vehicle is scheduled to be looked at by a dealer, but still recommend this be a safety issue!!
The 2016 Toyota Frame Rust Settlement (Burns v. Toyota Motor Sales, U.S.A., Inc.): This $3.4 billion class action directly addresses premature corrosion in 2007-2008 Tundras (and similar models). It claims Toyota "knowingly failed to apply adequate rust protection," leading to frame perforation despite later treatments like HOF. The settlement's "recurrent perforation" clause applies even after HOF. My rusted-through fuel tank strap and holes in the rear cross member qualify. HOF RO# [redacted]. Claim #[redacted] My 2008 Tundra SR5 TRD was treated with HOF in Nov 2017. In November 2025 my mechanic told me the gas tank was falling out as the straps that hold the tank in place were completely rotted out. And rust perforation was on the rear cross member. He instructed me to get a safety inspection at a Toyota dealership to document the rust. …
Frame mount for gas tank has rusted and fuel tank is dropping down. Last year an undercoating was applied by a Toyota dealer and is peeling off in certain areas. I believe pursuant to the class action lawsuit referred to as brian warner et al Toyota motor corporation my vehicle May be covered under warranty because the gas tank strap mounting is part of the frame. As of now, my mechanic advised me not to drive it as it is a safety hazard. I noticed the tank strap was hanging down from the frame and the gas tank was also hanging down while the vehicle was parked in my driveway.
Toyota acknowledges a problem with their air intake valve and has extended the warranty period. The warranty is too short, too little miles, and only covers the repair one time. My vehicle is experiencing this problem for the 3rd time even though they claim that their repair fixed the problem the first time, and claims no one else experienced the problem a second time (although I have).
I am having problems with my truck. When driving it. It looses power. Engine shakes.. Goes from okay to loss of power to back to having power. In codes are showing up when placed on the computer. I have replaced spark plugs and wires. I took the truck to Toyota and they advised me that their has been recalls with fuel pump and could be the problem I am having.
Rear left fuel tank bracket broke off from truck frame. It appears to have broken at weld. See photo. Noticed problem while driving due to bracket rubbing against driveshaft and scraping on road.
