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 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.

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.
