2025 Toyota Sienna Hybrid Driver assistance Problems

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)

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.

The Supplemental Restraint System (SRS), specifically the airbag system, is the component of concern. During a two-impact collision involving my 2025 Toyota Sienna XLE, none of the airbags deployed despite significant front-end damage that resulted in the vehicle being declared a total loss. The vehicle is currently in the possession of the insurance company or its storage facility. I do not know whether it has been released for salvage, but it may still be available for inspection. I, my wife, and our children were all wearing seatbelts at the time of the collision. After an oncoming vehicle struck the front-left portion of my vehicle while making a left turn, my vehicle lost control and collided with a concrete pillar. None of the airbags deployed during either impact. All occupants sustained injuries and were transported to the emergency department. I suffered injuries to my right leg, wrist, chest, neck and back. My wife sustained injuries to her neck, chest, back, and knee, and our children sustained injuries including head impacts. My wife and I continue to receive physical therapy. The vehicle was declared a total loss following the collision, and no dealer or independent repair facility has evaluated or reproduced the concern. The vehicle was inspected by the responding law enforcement officers at the crash scene, and a police crash report was completed. The insurance company (GEICO and Allstate Fire and Casualty) inspected the vehicle and declared it a total loss. To my knowledge, Toyota has not yet inspected the vehicle, and I do not know whether the Event Data Recorder (EDR) or Supplemental Restraint System has been analyzed. Prior to the collision, I did not observe any airbag warning lights, SRS warning messages, or other indications that there was a problem with the Supplemental Restraint System. The vehicle was operating normally before the crash.

See attached document for complaint. My husband and I purchased a Sienna, 7-passenger van, April 2025 and have received two safety recalls, the first being the lack of second-row seats being installed correctly presenting a safety problem, and later a possible problem with the backup camera. We purchased a vehicle of that size especially for the convenience of transporting family when they visit. Also, we have a granddaughter, husband and one-year old great-grandson who live nearby and thought having a van would be helpful for trips together. Unfortunately, all our hopes were diminished at being able to enjoy the reason we purchased such an expensive vehicle, $65,000+. We are an elderly, retired couple, considered the vehicle an investment, because our two previous Toyota vehicles had lasted us for 15 years with no problems. Therefore hoping our daughter and grandchildren would be able to use the van for many years. The van has been nothing but an Albatross, not being able to drive it with only two passengers, in the front, since learning of the first recall on the second row seats. The local dealer told me if I’d get an appointment and be at their door at 7:00 a.m. they could repair the camera. BUT, dealers have no fix from Toyota for the second row seats. However, I went on line to the Toyota web site and they have a “FIX” process listed. I cannot imagine how a vehicle maker can be allowed to sell a vehicle when they find out it has such safety hazards? We consumers can beg our Legislators to pass laws to that effect, but, hope your agency will take the lead on protecting us consumers since we know this Congress will do nothing. I ask your agency to please take action on this issue and prod Toyota to do something concerning the major safety hazards with their 2025 model Sienna vans.

"We were notified by Toyota that it was unsafe to transport our children in the second row seats in November 2025 and the vehicle was under a recall. This puts our children at risk. A letter from NHTSA stated Toyota would have a remedy by 12/6. The manufacturer (Toyota) confirmed this recall. Given that Toyota has not indicated a solution date for this and the problem was discovered in October 2025 I believe the manufacturer has failed or is unable to remedy this safety recall for our vehicle in a timely manner and would like to officially log a complaint with NHTSA.

I bought this van brand new. I quickly realized that the reverse camera view has some issues. I believe images are not clean and sharp, as it is supposed to, and has unreasonable amount of distortions. Cleaning the camera from outside didn't do anything. I also noticed that the bottom part of center blue alignment line is little bit to the right and not align with the top. I checked online and it appears that other owners are also suffering from this same issue. Toyota should recall all affected vehicle and fixed this issue as soon as possible as this is a major safety issue when backing up!
