My name is [XXX]. I am an automotive Technician and I have completed hybrid vehicle system training. I have a certification of completion for the hybrid training.I work for XXX [XXX] maintaining and servicing a fleet of vehicles. I am contacting NHTSA regarding a safety concern with a 2024 Toyota Sienna Hybrid that I inspected. The vehicle has an intermittent braking concern. The driver reported that while braking, the vehicle sometimes seemed to move or jump forward instead of responding normally to the brake pedal. On one occasion, the driver reported that the brakes did not respond as expected and the vehicle nearly proceeded through a red light. I inspected and road tested the vehicle, but I was not able to duplicate the problem at that time. I also performed a full system scan and found DTC P162B87 in the Hybrid Control system. I contacted a Toyota dealership regarding the concern and also asked about Toyota T-SB-0047-24, which appears to relate to a transition between regenerative and hydraulic braking on certain Sienna Hybrids. The dealership told me that the bulletin does not apply to this vehicle’s VIN. Because this is an intermittent braking concern that could potentially affect vehicle safety, I would like to report it to NHTSA and find out whether there are other similar complaints or any additional information available regarding this issue.

NHTSA complaint 11766679Three (3) separate systems failed. 1. Upon seeing cars ahead of us slowing down, my husband pressed the breaks to slow down to avoid collision. When he pressed on the breaks, instead of slowing down or stopping the vehicle, the brakes failed to engage, and caused a surge that compelled the vehicle to lurch forward. The lurch propelled our vehicle into collision with another vehicle. 2. Also, the forward collision warning system failed to alert or engage the breaks. Our vehicle was stopped by the impact of hitting the other vehicle, not by its own breaks. 3. The automatic breaking system also failed to engage at all prior to impact.
NHTSA complaint 11759813The contact owns a 2024 Toyota Sienna Hybrid. The contact stated that while driving at an undisclosed speed, the hatchback independently opened. No warning lights were illuminated. The vehicle was taken to a dealer where it was diagnosed and determined that the hatchback needed to be recalibrated. The vehicle was repaired; however, the failure persisted. The vehicle was taken back to the dealer where it was diagnosed and determined that the hatchback needed to be recalibrated. The vehicle was repaired; however, the failure persisted. The vehicle was taken back to the dealer again and was diagnosed and determined that the hatchback needed to be recalibrated. The vehicle was repaired; however, the failure persisted. The manufacturer was notified of the failure. The failure mileage was approximately 15,000.
NHTSA complaint 11757786I have never been in an accident in my 31 years of driving. However, I am worried that this van is going to cause me to be hit. Several times I have pulled out to make a left or right turn and my gas pedal does NOTHING. I can push it clear to the floor and NOTHING!!! Cars end up slamming on their brakes and honking at me but there's nothing I can do. This is EXTREMELY scary and a HUGE HUGE HUGE manufacturing flaw. There needs to be a recall for this to be fixed before people are injured.
NHTSA complaint 11754568Unexplained acceleration during braking which has caused the vehicle to appear to accelerate further during braking actions causing driver to apple brakes harder
NHTSA complaint 11751146Rear Tail Lights Failed... Brake and Signals work. This was repaired through the dealership. 4 connectors and housing replaced invoice shows part 909890-10942. I am writing to express my concern regarding repeated tail light failures on my black Toyota Sienna that appear to be caused by wiring connection issues. This defect creates a serious safety hazard for my family, other motorists, and pedestrians, particularly in rural areas where there is little to no street lighting. I live in the country, where many roads are unlit and visibility at night is already limited. Because my vehicle is black, it blends into the darkness when the tail lights fail. Drivers approaching from behind may not realize my vehicle is on the road until it is too late to stop safely, significantly increasing the risk of rear-end collisions. This issue is especially concerning because I frequently transport children in my vehicle. Their safety depends on other drivers being able to clearly see my vehicle at night. A tail light failure caused by a wiring defect could place them at unnecessary risk of serious injury or death if another vehicle is unable to see us in time. The defect also puts other drivers at risk. Motorists traveling at highway speeds on dark rural roads rely on tail lights to judge the presence, distance, and speed of vehicles ahead. Without functioning tail lights, they may have little or no warning that another vehicle is in their lane, particularly around curves, hills, or during poor weather conditions. This appears to be more than a routine bulb replacement issue. If the root cause is an unreliable wiring connection, the lights may work intermittently or fail unexpectedly, making it difficult for owners to recognize the problem before driving. An intermittent electrical failure is especially dangerous because drivers may believe their lights are operating normally when they are not. Started a case with Toyota 260715001670
NHTSA complaint 11750825Moving about 55 miles per hour on right lane of I-95 the Jeep in front of me braked abruptly. I braked hard but as my Sienna was quickly slowing down to stop, the brake pad felt spongy when it was slower and as I pressed even harder, it seemed to have stopped decelerating at that slower speed and that was when my Sienna slammed into the back of the Jeep. Happened today on July 15, 2026 at around 4:24 EST. I will also file this same report to Toyota. My wife and I are at the hospital getting checked, but my Sienna looked undrivable.
NHTSA complaint 11750717The power liftgate on my 2024 Toyota Sienna consistently fails to complete a full close-and-latch cycle. When activated, the liftgate begins its closing sequence normally but then aborts the cycle during the final stages of latching. The system emits an audible beeping signal and the liftgate reverses direction, reopening approximately one-quarter of the way. This failure occurs repeatedly when the vehicle is stationary with no external obstruction present. Multiple repeated attempts to close the liftgate using standard operation (key fob, interior switch, and exterior switch) result in the same failure pattern. The system does not complete a secure latch. Eventually, the liftgate can only be fully closed manually with physical force, bypassing the powered closing function entirely. This condition occurs intermittently at times but has become frequent and repeatable enough to prevent reliable use of the power liftgate system. No obstructions are present during operation. The local Toyota dealership service department observed this and indicated a lift gate adjustment is required, noting it is a known issue Toyota Customer Care has indicated they have no documented record of a known defect relating to this condition. However, multiple independent owner reports and dealer-level discussions indicate similar behavior may be occurring in other vehicles of the same model line, suggesting a potential systemic issue that may not yet be formally recognized. This malfunction raises potential safety concerns, including but not limited to: failure of the rear liftgate to fully secure and latch, increased risk of the liftgate remaining partially open or unlatched without clear driver awareness, and reliance on manual force to override an electronic safety system designed for automatic secure closure. I request that this complaint be documented for investigation and review to determine whether a defect trend exists in the power liftgate system of the Toyota Sienna platform.
NHTSA complaint 11746650When approaching a stop sign or light and while the brake is already engaged the car will accelerate lunging the car forward from 3-10ft while driver maintains the same pressure on the break pedal.
NHTSA complaint 11744764Center console malfunction. They were always items get slipped into it and unable to close which cause hazardous as the console unable to opem or close
NHTSA complaint 11744678I am the original owner of a 2024 Toyota Sienna Hybrid (VIN: [XXX]). The vehicle has required two significant engine repairs within the first 57,000 miles of ownership. Both repairs were performed at authorized Toyota dealerships under warranty. INCIDENT 1 — ENGINE REPLACEMENT (10,000 MILES): At approximately 10,000 miles, the engine developed severe knocking. The dealership determined the engine was defective and performed a complete engine replacement under warranty. INCIDENT 2 — OIL LEAK (57,000 MILES): At approximately 57,000 miles, the engine developed an oil leak between the oil pan and the timing belt cover. The dealership repaired the leak under warranty. The dealership informed me that this repair carries only a one-year warranty on the work performed. The fact that the engine required complete replacement at only 10,000 miles indicates a manufacturing defect. The second engine issue at 57,000 miles suggests a pattern of powertrain reliability problems. I contacted the Toyota Brand Engagement Center (Case #XXX) and spoke with both an advocate and a supervisor. Toyota declined to offer any extended powertrain coverage and would only agree to review future issues on a "case-by-case basis." I am concerned about the safety and long-term reliability of this vehicle's powertrain given the recurring nature of these engine failures. A complete engine failure at 10,000 miles on a brand-new vehicle is not normal wear and tear — it is a defect. I am reporting this so that NHTSA is aware of potential systemic engine issues with the 2024 Toyota Sienna Hybrid.

NHTSA complaint 11742968What component or system failed or malfunctioned, and is it available for inspection upon request? -The engine malfunctioned. It is available for inspection. How was your safety or the safety of others put at risk? -The engine went out at 77k miles in the middle of driving with no warning. Could have caused a serious accident. We have always done proper oil changes. The rods separated from the pistons and punched a hole in the engine block. Has the problem been reproduced or confirmed by a dealer or independent service center? The dealer diagnosed it and our mechanic said this has happened with Toyotas too recently Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -no Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? -no warnings or messages before the failure of the engine.
NHTSA complaint 11740297While applying the brake at the stop light. (25 to30 mile speed limit zone) The Toyota hybrid sienna start to accelerate for split 5 or more seconds. I have to apply the brake harder even though I was already applying the brake to slow down because the light was red and the are several cars in front of me. For the first time I was scared thinking about rear ending some one in front of me or the Toyota Lexus incident where it accelerated and everyone died flashing through my mind. It was not a good feeling.
NHTSA complaint 11739982I notice the driver seat had a clip that popped off unto my carpet, when inspected it came off the seat rail. While moving my seat back using the electronic seat lever a white clip with two metal bearings was sticking out, I notice the ball bearings were not in place and had came off the white clip. Yes, it is available for inspection. This pose a safety concern as the seat rails will not function correctly when moving seat or using the memory seat buttons for each driver. I have not brought the vehicle to a dealer to inspect as there is a estimate fee involved. I am currently out of my 2 year toyota care warranty. I am not seeing any warning lamps or messages besides the seat making a clicking noise when I move the seat back and forth.
NHTSA complaint 11739212The contact owns a 2024 Toyota Sienna. The contact stated that while approaching a stop light and pressing the brake pedal the vehicle crashed into the rear of a second vehicle. During the crash the collision avoidance system did not activate and no air bags had deployed. No injuries were reported. A police report was taken at the scene.. The failure mileage was 25,000.
NHTSA complaint 11739102Stepping on brakes - Car slows then accelerates a few seconds and lunges forward a couple of feet. Extreme safety issue. This occurred yesterday with my sister in the car and we almost rear ended the vehicle stopped in front of us. I have complained to the Cumberland Toyota dealership in the past and was told if they cant recreate the issue and it doesn't happen all the time there is no way to fix the issue. Yesterday I was almost in an accident because of this faulty design/anomaly associated with my car. This lunging forward is not suppose to happen and I want it fixed Toyota needs to come up with a resolution before it kills me. I have purchased this vehicle new 2024 and it has been happening since purchase - NOW its really bad
NHTSA complaint 11738078The driver's side mirror vibrates when the vehicle is at speed. I've been to two dealers who say that it's normal, and everything is intact and installed correctly. When driving, the mirror vibrates a lot, which is a safety issue when trying to use the side mirror during changes, etc.
NHTSA complaint 11735267The contact owns a 2024 Toyota Sienna Hybrid. The contact stated that while the vehicle was at a complete stop, while attempting to depress the brake pedal, the vehicle unexpectedly lunged forward. There was no warning light illuminated. The contact stated that the failure had occurred several times without a warning light illuminated. The vehicle was taken to the dealer several times; however, the failure could not be duplicated. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 31,600.
NHTSA complaint 11733541I am reporting a possible safety defect in my 2024 Toyota Sienna Hybrid AWD, VIN [XXX] . The vehicle intermittently surges, lurches, or creeps forward while I am pressing the brake pedal and attempting to slow or stop. It feels as though the vehicle briefly adds power or braking force momentarily decreases even though my foot remains on the brake. The sensation is not normal creep alone; it feels like a brief unintended forward push while braking. The problem is intermittent, which makes it difficult to predict, but it creates a safety concern because it can happen when slowing, stopping, or maneuvering at low speed. I am concerned this could increase stopping distance or cause the vehicle to move forward unexpectedly. I am requesting investigation of possible defects involving the braking system, hybrid regenerative braking transition, brake actuator, pedal sensing, or related control software. It happens daily.

NHTSA complaint 11728879While driving on highway, on 3/11/26, car powered down. I had to coast to side of highway. I was able to turn vehicle on after several minutes, but SEVERAL system malfunction error messages (hybrid, accelerator, pre-collision, tpms, airbag, engine…) appeared. The vehicle would not accelerate beyond 10mph. Once I moved it to a safe location, I had the vehicle towed to the dealership. The dealership technician was able to replicate the issue during test drive. The technician apparently had the vehicle towed back to the dealership last night. The car has had other related issues since June 2024 when I bought it. The TPMS system, the accelerator system, and the airbag system have all malfunctioned independently. The accelerator system malfunctioned in Jan. I had to pay for a replacement fuse despite the warranty. The vehicle is modified with Braunability equipment for wheelchair access. These modifications are approved by Toyota and were completed by MobilityWorks. Aside from the vehicle itself being unsafe to drive, the passenger sliding door has had numerous problems. On 3/07/26, the door mysteriously slammed shut after opening and would not open again. These are all dangerous situations that could have resulted in fatal accidents.
