| May 2026 | ENGINE | What 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. | Crash: No Fire: No | Unknown |
| May 2026 | UNKNOWN OR OTHER | While 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. | Crash: No Fire: No | Unknown |
| May 2026 | SEATS | I 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. | Crash: No Fire: No | Unknown |
| May 2026 | FORWARD COLLISION AVOIDANCE | The 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. | Crash: Yes Fire: No | 25,000 |
| May 2026 | UNKNOWN OR OTHER,SERVICE BRAKES | Stepping 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 | Crash: No Fire: No | Unknown |
| May 2026 | VISIBILITY | The 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. | Crash: No Fire: No | Unknown |
| Apr 2026 | SERVICE BRAKES, HYDRAULIC | The 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. | Crash: No Fire: No | 31,600 |
| Apr 2026 | VEHICLE SPEED CONTROL,SERVICE BRAKES | I 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.

| Mar 2026 | VEHICLE SPEED CONTROL,UNKNOWN OR OTHER,ENGINE | While 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. | Crash: No Fire: No | Unknown |
| Feb 2026 | ENGINE | My 2024 toyota sienna suddenly stopped for 2-3 seconds while driving in the city roads. I was caught off-guard with that behavior. I kept pushing on my gas pedal and after few hard pumps the power came back. This happened couple of times so far. Not sure what the main problem is. | Crash: No Fire: No | Unknown |
| Feb 2026 | POWER TRAIN,ENGINE | The contact owns a 2024 Toyota Sienna. While the contact’s wife was driving 5 MPH out of a parking lot and attempting to make a left turn, the vehicle suddenly lost motive power and stalled. After approximately 3- 4 seconds while depressing the accelerator pedal several times, the vehicle eventually accelerated as needed. The vehicle was driven to the residence. There were no warning lights illuminated. The vehicle was not taken to the dealer to be diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was 68,000. | Crash: No Fire: No | 68,000 |
| Jan 2026 | TIRES | The contact owns a 2024 Toyota Sienna. The contact stated that upon starting the vehicle while parked in the garage, the low tire message was displayed. The contact stated that the tire was reinflated. The vehicle was taken to the local dealer and the contact was informed that the issue might be weather-related. There was no repair performed. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 17,826. | Crash: No Fire: No | 17,826 |
| Dec 2025 | TIRES | Incident Description (Firestone Destination LE3 – P235/65R17) I purchased four new Firestone Destination LE3 tires (size P235/65R17, DOT IW2 8ILE31) and within the first week three of them developed noticeable bulges in the sidewalls. I returned to the tire service center, and they replaced the three tires due to the bulging. The following week, new bulges appeared again in the sidewalls on multiple replacement tires, for a total of six affected tires. Sidewall bulging creates a risk of sudden tire failure and loss of vehicle control, and I do not feel the tires are safe to drive on. One service center stated this was “normal from driving on roads,” but I disagree due to the number of tires affected in such a short time. The condition has been repeated and confirmed by multiple service centers. The tires remain available for inspection upon request. There were no warning lamps or messages before the bulges appeared. The issue began immediately after installation of the first set, and the problem persisted with the replacement set. In my assessment, the repeated sidewall bulging indicates a potential structural or manufacturing defect. | Crash: No Fire: No | Unknown |
| Oct 2025 | VEHICLE SPEED CONTROL,SERVICE BRAKES | Looked online to see if other Sienna drivers had the same issue with the hybrid system. Brakes are accelerating a bit even when already pressing on the brakes. It has happened enough times to be concerning. We have not taken it to the dealearship as of yet but will be getting in touch soon , now that we know it's a known issue. No warnings from vehicle. | Crash: No Fire: No | Unknown |
| Oct 2025 | STRUCTURE,UNKNOWN OR OTHER | Dear Sir/Madam, I am writing to formally raise a complaint regarding a serious and ongoing issue with my 2024 Toyota Sienna XLE AWD, purchased in April 2024 in Illinois. From the very first day, the trunk door has not functioned properly — often failing to close, randomly opening, or requiring manual force to shut. Despite repeated service visits across multiple states (IL, SC, NC) and investing considerable time, fuel, and lost income as a contractor, this issue persisted for over 18 months, creating safety concerns and inconvenience for me and my family. Key Issues: Trunk door opens on its own – even while reversing, creating serious safety risks. Malfunctioning power close mechanism, requiring manual closure frequently. Unreliable performance: door would close, then immediately re-open. Visited Toyota service centers at least 6 times across 3 states. Each visit took 2–3 hours, costing me work hours as a contractor. Customer service experience has been poor, especially with manager Patte, who: Failed to schedule proper service appointments. Directed me without coordination. Refused to escalate my request or connect me to her manager. Dismissed my request for compensation by saying, “It’s your issue.” Please help me on this issue. Thanks in advance. | Crash: No Fire: No | Unknown |
| Oct 2025 | SEATS | When a lever is pulled, the second row seat can move freely back and forth on a track until the back of the seat is returned to the upright position. I was driving at highway speeds and had to brake suddenly. The seat was at the back of the track with the lever pulled, and it slammed into the back of the driver seat, hurting my back. It stuck there putting pressure on the seat (which could be felt) until I stopped and had to use force to make it slide back. | Crash: No Fire: No Injuries: 1 | Unknown |
| Oct 2025 | STRUCTURE | The driver side power sliding door failed to detect my [XXX] and ended up squishing it and we struggled for over a minute for the door to open. I have a video of the incident as it was captured by our security cameras, but I cannot upload it here. This was no the first time the doors have failed to detect someone.

| Oct 2025 | SUSPENSION,AIR BAGS,STRUCTURE | Keeps bottoming out suspension is specification is stated at 5.6 inches and I measured 3.3/4 unloaded never get a response on my complaints from my last repair and resolution on what they admitted that suspension was too low and wouldn’t put it in writing only saying that vantage mobility saying that it’s height requirements are as stated by vantage but no mention of ground clearance that I wanted them to verify that it’s specifications are stated at 6.5 inches and i measured 3 3/4 empty then they tell me not to go by specs and I’m a retired from wright Patterson Air Force base in the engineering department with logistics command and I’m like really guys you have to to have a specifications for a engineered system and they can’t even call back after they admit you have to go by specs! And then the authorized repair specialist tells me i had a bad brace on the front tire that was welded wrong and didn’t even mention it on the invoice or reported it to vantage mobility to call me about anything I had concerns about ? | Crash: No Fire: No | Unknown |
| Sep 2025 | UNKNOWN OR OTHER | On various occasions while braking there is a sudden acceleration that occurs. Generally lasting less than 5 seconds. More noticeable going down hills but has occurred on standard driving. Date provided is most recent occurrence after service from Marietta Toyota for recall and 25k service. | Crash: No Fire: No | Unknown |
| Sep 2025 | VISIBILITY/WIPER | Wobbling vibration on exterior mirror, driver side. It looks like incoming vehicles shake sideways. This happens on any bumpy road and it is easier to observe at highway speeds. Purchased on [XXX]. Vehicle is available for inspection. The distorted image resulting from mirror wobbling affects driver's awareness of surroundings, visibility gets worse at nights/rain due to blurred lights. This can lead to an accident. My regular dealerships in Milford, CT have confirmed the issue but have not been able to provide a fix. They say the vibration is normal. I do not believe so as the passenger side mirror never has issue like that. I have first noticed this issue a couple of weeks when driving on highway. Posting my case online has gotten at least 4 people reporting the same issue with the Sienna since 2021 in multiple trims. Similar issue on RAV4 reported on [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Sep 2025 | SERVICE BRAKES | On rare occasions (about once every 500 miles), when uniformly applying force to the brake pedal, the deceleration suddenly ceases and the vehicle seems to jerk forward. To a passenger, it feels like the driver's foot slipped off the brake pedal, but the driver continued to provide the same uniform force to the brake pedal and lost all deceleration. Typically, the driver is startled and presses significantly harder on the brake pedal jerking all occupants forward. The brakes re-engage and continue the deceleration at a much higher rate. Toyota addressed this problem with TSB 4724 which involved reprogramming the brake actuator assembly. This corrected the problem for about 3 months, but it is now occurring again. When the car was taken to the Toyota dealer again, the technician stated that TSB 4724 was cancelled, he could not duplicate the action (even though he was told it only happened on rare occasions), and claimed that the "brakes function properly as they should." Fortunately these loss of braking incidents have only occurred on dry pavement so that the driver did not lose control of the car when slamming on the brakes to compensate for the loss of deceleration. Coming down a hill on a snow covered road could have caused the vehicle to slide into an oncoming lane. It is my speculation that there is a null spot that exists during certain circumstances which causes there to be a "gap" between when this hybrid vehicle transitions between the dynamic hybrid brake and the friction wheel brake. Both braking systems independently work fine, but the transition between them (on rare occasions) does not occur continuously. This causes the driver to experience an unexpected loss of braking which, under the right conditions, could cause the driver to loose control of the forward motion of the car. As an engineer, I feel it is unacceptable for a safety system (braking) to not properly operate 100% of the time! On a Toyota owner's site, others have seen the same. | Crash: No Fire: No | Unknown |
| Aug 2025 | SERVICE BRAKES | Intermittent unexpected acceleration during braking. This has occurred while braking into a downhill as well as at low speeds when turning into a parking space. Additional braking is required to stop vehicle or maintain desired braking. | Crash: No Fire: No | Unknown |
| Jul 2025 | STRUCTURE | Trunk will not open or close properly. Made a screeching sound when you open or close initially. Then eventually it stops opening or closing unless you assist. | Crash: No Fire: No | Unknown |
| Jun 2025 | UNKNOWN OR OTHER | On June 5 th the vehicle was going approximately 50 miles per hour in the middle lane. I placed on the brakes suddenly and car lost power and stalled out. Unable to restart vehicle for 5-10 minutes on the freeway. Significant safety concern due to vehicles sudden stall out in mid the highway traffic and unable to restart car. Almost hit from behind as well as others that followed from behind. On Jun 7th vehicle was taken to the Toyota dealership and car checked by special mechanic and reported that they were unable to reproduce the stalling or issues with restarting the vehicle.Dealership feels there is nothing wrong with vehicle. There was 2 warning messages on vehicle when stalled suddenly 1-Charge 2- Fluid | Crash: No Fire: No | Unknown |
| Jun 2025 | SERVICE BRAKES | When going down hill while braking, the brakes will release causing the car to lurch forward and then they grab again. It’s intermittent and Toyota has a TSB on it but the dealership with not fix it because they can’t duplicate the problem. It can cause people to take their foot off and of the brake pedal and trying to apply it again. Which can cause someone to rear end another car. | Crash: No Fire: No | Unknown |
