| Jun 2025 | STRUCTURE | The lift gate strut bent when I tried to close the rear door, then when I tried to open the door to see what the issue was, the strut exploded. The parts went flying and almost hit me in the face, I could feel the air on my cheek as it blew past me. The spring and metal parts inside the strut shot all the way across my cul de sac, and the noise it created sounded like a gunshot. My neighbors came out of their houses to see what happened because it was so loud. We have an appointment at the dealer tomorrow to get it looked at. If I was standing any closer the spring would have hit me in the face; my children luckily were in the car already, if it happened a minute earlier it could have hit them. I noticed after the fact that the gaps in the back door are uneven when it’s closed, and I wonder if the door is installed unevenly and that put pressure on one side more than the other causing the strut to break. I can’t take a picture of the broken strut because I am too afraid to open the rear door in case the other one explodes. | Crash: No Fire: No | Unknown |
| Jun 2025 | SERVICE BRAKES | In general the braking system on this vehicle is poor. The van does not seem to want to stop unless you apply a lot of pressure on the brake pedal. I have taken the vehicle to the dealership who explained to me that the braking operation is normal. I replied “so the poor brake design was intentional”. The dealer said the braking system takes a little while to get used to. I have contacted Toyota corporate 5 times to express my concern about the brakes. The customer service representatives say that they will pass my concerns along. I personally own 6 vehicles. The brakes on this Toyota are by far the worst. It is not even close. I do not feel like this vehicle is safe. This is a minivan that is used to move families around. I do not feel safe in this vehicle and most importantly I am worried every time my wife drives this vehicle that someone will slam on the brakes in front of her the van will not stop in time. Toyota is the world’s largest auto maker, they can and should produce a better braking system than what is available with this van. This is unacceptable with braking technology available at this time in automotive history. Their lack of response to my concerns in also disappointing. Thank you for hearing my concerns. | Crash: No Fire: No | Unknown |
| May 2025 | VEHICLE SPEED CONTROL,FUEL/PROPULSION SYSTEM | There are no messages/warnings. The vehicle will surge at very low speeds such as when I am coming to a stop, trying to avoid a person in a parking lot etc. It was SO scary this evening as I accelerated into a very very busy intersection...I pressed on my brakes harder and it was instant - but about 1 second (which is a LOT in this scenario) later it then slowed instead of accelerated. I have owned the vehicle almost a year. I will be bringing in for inspection this week and let the dealer know. I have put on about 11K in miles and would say this has happened a dozen times thus far with this evening being the scariest one yet. I figured it was just something normal for a hybrid but as I researched online - many people have this issue. TOO SCARY for me and dont want to hurt anyone or myself. | Crash: No Fire: No | Unknown |
| May 2025 | SERVICE BRAKES | When decelerating either for a traffic light or otherwise at the slow speed when the break is applied before coming to a stop, the car accelarates and then I have to slam on the breaks. this is very dangerous | Crash: No Fire: No | Unknown |
| May 2025 | UNKNOWN OR OTHER | The interior dash lights, when turned up to max brightness, take several seconds to read when making adjustments to the climate controls. These dim controls pause a hazard as it takes your attention away from driving. The dealer told me that they could not make them brighter. The issue is at night and day times. | Crash: No Fire: No | Unknown |
| Apr 2025 | SERVICE BRAKES | When I am rolling to a stop, or lightly pressing in the brakes, the car will occasionally jolt forward and I have to slam on the brakes. It is not every time but has happened many times since buying the car new. I brought it into the dealership and they could not replicate it, but it makes me so scared to drive. This could result in an accident or the hitting of a pedestrian. No warning lights. | Crash: No Fire: No | Unknown |

| Jan 2025 | VISIBILITY/WIPER | Driver side outside rear view mirror shakes and makes driver nauseous. Mirror was replaced in December and replacement mirror shakes as well. Right side (passenger) doesn't shake. Vehicle now has 6500 miles on it. Original equipment windshield has a wavy appearance for the right 1/3 of it (in front of the front passenger seat). Both issues have been brought up with Mitchell Toyota in San Angelo, TX. The dealer will not replace the driver side mirror again, saying "some movement is allowable", even though the passenger mirror doesn't do it at all. They also said that the windshield waviness is "normal". These issues are in addition to other issues I've had with this Sienna, from moldly HVAC smell that caused my eyes to sting and tear up last week. | Crash: No Fire: No | Unknown |

| Oct 2024 | ENGINE | Hello, leader. I bought my car (Sena Platinum Edition) for three months. Due to a mistake in the appearance, I need to replace the engine now. My new car will definitely depreciate if the engine is replaced, so I hope Toyota headquarters can refund me in full. I need to buy a new Sena! My house is full of Toyota cars, no matter what the result of Toyota Company's handling? I will still choose to buy a Toyota! Thank you! | Crash: No Fire: No | Unknown |

| Sep 2024 | UNKNOWN OR OTHER | I was driving the speed limit on a sunny day and heard a loud pop and glass breaking which was my sunroof exploding. There is no damage to my roof to indicate anything hit my vehicle. | Crash: No Fire: No | Unknown |
| Aug 2024 | WHEELS | We had a complete tire blowout of the rear driver tire in the desert, the temperature was 108° ambient. Toyota did not mention to us nor did the dealership that the car does not have a spare tire. We were 50 miles from any service Including cell service, I had to walk a mile to find cell service meanwhile two of our kids experience heat exhaustion. It took four hours to get the Vehicle towed. In that time our children experience heat exhaustion and had to be taken to the hospital. This is a huge oversight part to not make the customer aware that the vehicle especially family vehicle does not have safety equipment like a spare tire. In the desert this is a life and death issue that was not addressed by the dealership nor Toyota. All that is given is an inflation kit. We were not told by the dealership that a card did not come with What turns out to be essential equipment in the middle of a desert. | Crash: No Fire: No Injuries: 2 | Unknown |
| Aug 2024 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | When crossing a one-way road with oncoming traffic from the left, a vehicle that has recently passed might be triggering the forward collision avoidance system which cuts off throttle control to the Sienna, even when the passed vehicle is well out of the way. It is unknown if the collision avoidance feature is being triggered as there are no warning lights or messages in the display. This results in the Sienna having no accelerator response and sitting “dead in traffic” sideways in front of oncoming cars. This this is the second time this issue has occurred and today I was nearly t-boned by on-coming vehicles as there was no throttle response to move the car forward. This issue has been reported in 4th generation Sienna (‘21-‘24) forums on Facebook. This issue puts at risk vehicle occupants as well as other vehicles on the road. | Crash: No Fire: No | Unknown |
| Jul 2024 | SEATS | The 3rd row seats do not remain stowed when passing over a speed bump or dip in the road. Depending upon the speed of the vehicle, the seats might jump up several inches and almost return to the fully stowed position with a loud thud. The seats then bounce up a few inches from the fully stowed position and remain unsecured. It's possible that the seats might unexpectedly fully open at higher speeds. | Crash: No Fire: No | Unknown |
| Jul 2024 | SEAT BELTS | My child [XXX] ) engaged the automatic locking retractor (ALR) and as it wound back in it wrapped around his neck. By the time we got to him it was tight enough that it was difficult to move or rotate or slide the seatbelt over his head, and we ultimately cut the seatbelt to free him. In addition to the actual safety incident, I was very surprised to learn that this was even possible. I had never heard of this safety issue, and had absolutely no game plan or awareness about this issue. I saw the SBIR program addressing innovation in ALR systems which is exciting! However I would also strongly encourage some sort of awareness campaign or warning messaging to raise awareness and ensure parents keep belt cutters in their cars. Thanks for your time and considering our incident for future regulation, innovation, and awareness campaigns!
