Dear NHTSA Office of Defects Investigation, I am writing to formally submit and expand my urgent vehicle safety defect complaint against Toyota Motor Sales, U.S.A., Inc. regarding my 2025 Toyota Sienna XSE Hybrid, which suffered a total electronic and mechanical braking failure resulting in a major crash on [XXX], along [XXX] in Washington, DC. 1. Incident Overview & Prior Inspection History On [XXX], while operating the vehicle as a commercial cab carrying two passengers, the vehicle experienced a total electronic/mechanical braking failure. I purchased this vehicle brand new from Passport Toyota on [XXX], with 36,358 miles at the time of the crash. Exactly one month prior, on [XXX], the vehicle underwent an authorized manufacturer recall service and cleared a dealership Multi-Point Inspection. It is deeply concerning that a brand-new vehicle cleared a comprehensive inspection only to suffer catastrophic brake failure four weeks later. During the incident, the emergency brake failed to engage because the entire electronic and braking system had completely shut down. The vehicle accelerated uncontrollably over multiple speed bumps for approximately one mile before crashing into a security fence at [XXX]. Despite the high-impact collision, none of the airbags deployed, indicating a catastrophic failure of both braking and safety restraint systems. 2. Suspected Document Tampering & Signature Forgery Following the crash, Toyota requested an authorization signature. I distinctly remember signing a one-page document specifically limited to vehicle pickup and transport. However, Toyota subsequently presented a two-page document containing expanded data extraction clauses. I strongly suspect that Toyota or its agents altered the document and copied/pasted my digital signature onto a modified page without my knowledge or consent. Dashcam Video: Documents complete loss of braking control. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The foam under the headrest was discovered to be cracked when the cover was removed while performing the the repair on the recall for the babies eating the foam (can't find the recall paperwork now). The instructions provided with the remedy for the recall said if the foam was cracked to contact evenflo's hotline immediately. I contacted evenflo on July 28th via phone and was emailed a request for more information. I provided more information and video of the damage on XXX. No reply was received acknowledging the receipt of the requested information so I emailed on XXX asking to confirm receipt. I emailed again on XXX, and Evenflo finally responded on XXX with the following reply: "Thank you for reaching out to Evenflo regarding your Revolve360 car seat. I'm sorry to hear your headrest foam has become broken/detached. If the foam is detached, tape is allowed and no glue, and the seat pad holds the foam in place, the seat is still safe to use. If the foam is broken in larger pieces, you have all the pieces, they fit together like a puzzle, tape allowed and no glue, and the seat pad holds the foam in place, the seat is still safe to use. Evenflo tests all car seats to energy levels approximately twice that of the federal crash test standard. Additionally, our engineers developed the Evenflo Side Impact test protocol, which simulates the energy in severe 5-star government side impact tests conducted for automobiles. Now we are leading the industry by incorporating a dynamic rollover test. Rest assured, as long as the foam is in place, broken or not, it is still doing its job of absorbing crash forces." I no longer feel safe using the carseat with my [XXX] and wanted to reach out to the NHTSA to verify that cracked headrest foam is safe to use.

The contact owns a 2025 Toyota Sienna Hybrid equipped with Firestone Tires, Tire Line: FT 140, Tire Size: 235/65/R17, DOT Number: 1WT87FT01. The contact stated that there was a screw in the tire. The contact stated that while driving 70 MPH there was a sound of an object in the tire. The message that the air pressure was low was immediately displayed. The tire pressure indicated 25 PSI. The driver was able to take the off-ramp but was unable to locate the spare tire. A good Samaritan attempted to assist. The driver was able to locate the Fix-A-Flat and a compressor, but the tire failed to hold air. The contact stated that the hole in passenger’s side rear tire was too big to be sealed. The contact was unaware that the vehicle did not have a spare tire. The contact was on the side of the road for two hours. The tire was changed and plugged by her husband after two hours of being stranded. The contact had enough fuel to run the air conditioner. The tires were previously rotated. The contact stated that the situation could have been worse, and not having a spare tire puts the drivers in a dangerous situation. The failure mileage was approximately 11,474.

While driving my 2025 Toyota Sienna XLE with Sure Grip Push‑Rock electronic hand controls, the acceleration suddenly stops working without warning. When this happens, the hand control will not accelerate at all — only the brake still works — leaving me coasting in traffic with no way to speed up. This has happened multiple times at different speeds and creates an immediate danger because I can only slow down or stop, not accelerate out of the situation. At the same time these acceleration failures occur, the vehicle shows a “SRS Airbag System Malfunction” warning. Toyota’s internal records show the airbag system had faults before I bought the vehicle. The airbag warning and the acceleration failure often appear together, which makes me believe there is an electrical or wiring problem affecting multiple systems. I also discovered that Toyota documented underbody impact damage from a pothole months before I purchased the vehicle. This damage was not disclosed to me, and CARFAX does not show any record of this damage, even though Toyota’s own service history confirms it. The CARFAX report I received states “No accidents or damage reported to CARFAX”. I have owned multiple BraunAbility‑converted vehicles, and all of them have had electrical issues. BraunAbility cuts out the bottom of the vehicle for the lowered‑floor conversion and splices in their own wiring harness, which I believe is causing repeated electrical problems across different vehicles, including this one. Because the acceleration fails, the airbag system shows active faults, and the wiring appears to interfere with the vehicle’s safety systems, I am reporting this as a serious safety hazard.

Flash reprogramming allows the Electronic Control Unit (ECU) software to be updated without replacing the ECU. Flash calibration updates for specific vehicle models/ECUs are released as field-fix procedures described in individual Service Bulletins. This bulletin details the Global Techstream+ (GTS+) ECU flash reprogramming procedures and outlines use of the Technical Information System (TIS) and the Calibration Update Wizard+ (CUW+). To ensure the correct ECU software is installed, ECUs will require a Security Signature before the ECU will initialize the flash reprogramming sequence. This bulletin also details the process for acquiring a Security Signature from TIS during the GTS+ ECU flash reprogramming process.

Some 2025 – 2026 model year Crown, Crown Signia, RAV4 Hybrid, and Sienna Hybrid vehicles with an A25A engine may experience a MIL ON with Diagnostic Trouble Code (DTC) P145011 (Fuel Tank Pressure Sensor Circuit Short to Ground). This condition is more prevalent when the ambient temperature is 15°F or lower. To correct this condition, an improvement was made to the Fuel Tank Vent Valve.
