2004 TOYOTA TUNDRA — Complaint #2121866
Open-data reference.
NHTSA Complaint about STRUCTURE:FRAME AND MEMBERS filed August 19, 2025
NHTSA complaint #2121866 (ODI reference 11681547) concerns a 2004 TOYOTA TUNDRA and was filed on August 19, 2025. The owner reports the failure occurred on July 29, 2025. The vehicle had 150,000 miles on the odometer at the time of the incident. The report was geocoded to Florida based on the filer's self-reported location. The affected component is categorized as structure:frame and members, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same TOYOTA TUNDRA cohort independently describe similar structure:frame and members failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2004 TOYOTA TUNDRA shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The contact owns a 2004 Toyota Tundra. The contact stated that on several occasions, while driving at undisclosed speeds and then parking the vehicle, the contact observed oil leaking from the vehicle. The contact stated that on another occasion, while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was inspected, and the contact observed corrosion and holes on the frame of the vehicle, and the motor mounts were rusted, causing the engine to run abnormally low. The vehicle was towed to an independent mechanic to be diagnosed, and it was determined that the vehicle was flexing due to the holes throughout the frame of the vehicle. The mechanic was unable to lift the vehicle due to the excessive corrosion. The vehicle was deemed unsafe to drive. The manufacturer was notified of the failure. The failure mileage was approximately 150,000.
