2023 TOYOTA SIENNA HYBRID

The contact owns a 2023 Toyota Sienna Hybrid. The contact stated that her husband pressed the automatic liftgate button to close, unaware that their child was near the trunk. The contact's son's left hand became trapped beneath the liftgate, and her husband had to yank the liftgate open to free the child's hand. The child received medical attention for bruising on his left hand. The vehicle was taken to the dealer; however, the vehicle was not yet diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 60,000.

Front brakes make a clicking noise that happens when accelerating and breaking, the brake pads may have some play or even the calipers may be malfunctioning. Vehicle is still under warranty and Toyota service center refuses to address the issue. They want me to spend $160+ to have them grease the brake pads, but they don't guarantee that this will fix the problem. On a fairly new hybrid van that has almost no wear on the brakes, this shouldn't happen, and when it does, Toyota should acknowledge and address the issue.

The vehicle experienced water intrusion into the interior cabin shortly after delivery in 2023. The water intrusion affected electrical components related to the airbag and Supplemental Restraint System (SRS). The vehicle remains in my possession and is available for inspection upon request. Moisture exposure to airbag and SRS components presents a serious safety risk because these federally regulated systems may fail to deploy, deploy improperly, or deploy unexpectedly in the event of a collision, increasing the risk of injury or death. The issue was reported multiple times to authorized Toyota dealerships while the vehicle was under factory warranty, and repair attempts were made; however, the water intrusion and related safety concerns were not resolved. The manufacturer and its authorized dealers were made aware of the defect through repeated service visits and customer complaints. Warning indicators related to the airbag/SRS system appeared after the water intrusion occurred, and the defect first manifested within weeks of vehicle delivery in 2023.

While turning right at approximately 5–10 mph, the vehicle was struck on the front passenger side. The impact caused moderate intrusion of the passenger door, severe damage to the front-right corner of the vehicle, and damage to the dashboard. Despite the structural damage and intrusion into the occupant compartment, none of the airbags deployed, including driver frontal, passenger frontal, side torso, or curtain airbags. Both occupants were wearing seatbelts, which activated normally. The driver sustained a right-side rib fracture caused by seatbelt force, required ambulance transport to the emergency room, and continues to experience ongoing symptoms. A child passenger seated in the front passenger seat struck her head against the window, resulting in a brain concussion with symptoms including headache and dizziness, requiring emergency medical evaluation. No airbag warning lights were present before or after the crash. The vehicle is preserved in post-crash condition and is available for inspection. This appears to be an airbag system failure / crashworthiness defect that resulted in enhanced injuries due to airbag non-deployment.

Brakes will intermittently lurch when coming to a stop with normal braking pressure. The lurch feels like the brakes have stopped working and the driver has to press harder on the brake to avoid rear ending the vehicle in front. Brake pedal feels normal the entire time. Dealership is unable to duplicate on a test drive since the issue is intermittent.

The contact owns a 2023 Toyota Sienna. The contact stated that while driving 65 MPH, there was a popping sound coming from the sunroof, and the contact discovered that the sunroof had shattered. Neither the dealer nor an independent mechanic was contacted. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 70,000.

The contact owns a 2023 Toyota Sienna. The contact stated that while driving, the fuel gauge indicated there was 121 miles of fuel available. The contact stated that within twenty miles, the fuel gauge indicated that the fuel tank was empty. The contact stated that when the gauge indicated 170 miles available, the fuel usage decreased quickly. In addition, the contact stated that the failure had occurred several times. The contact stated that the vehicle was purchased and modified for transporting the contact’s disabled son. The Freedom Motor company provided the modification requests. The contact stated that the vehicle was taken to the modification company several times, however no assistance was provided. The contact was advised to always keep the fuel tank full. The contact stated that it was very hot and dangerous to be driving a vehicle and running out of fuel while transporting her disabled son. The manufacturer was not made aware of the failure. The failure mileage was unknown.

When I go to brake the brakes seem to malfunction and skip engagement. I’ve had acceleration happen in the vehicle when I brake. At one time this caused my speed to jump while braking, I went from 5 to 10 MPH. This now happens several times a week.

The contact owns a 2023 Toyota Sienna Hybrid. The contact stated while driving and depressing the brake pedal to come to a stop, the vehicle jolted. The vehicle was taken to the dealer, where the contact was informed that the vehicle was operating as designed. Additionally, the contact stated that upon starting the vehicle, the messages "Parking Brake Malfunction", "Parking Brake Unavailable" and "Door Ajar" were displayed. The gear shift indicator light and the parking brake warning light were illuminated. The vehicle was taken back to the dealer, where it was diagnosed that the main wiring harness underneath the gear shifter was corroded. The dealer informed the contact the wiring harness would be replaced at the contact's expense. The contact stated that the failure occurred because there was no protective shielding around the wiring harness. The vehicle was not repaired due to the cost. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 44,242.

The contact stated that the sound came from the front and the rear of the vehicle. The vehicle was taken to the dealer twice; however, the contact was informed that the sound was due to normal wear and tear. In addition, the contact was informed that the vehicle was safe to drive. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure but provided no assistance. The contact was advised to take the vehicle to another dealer for a second opinion. The failure mileage was approximately 52,200.

multiple times this has been an issue. I stepped on the break and the car essentially leaps forward typically when going up down or straight. In November 2024 it happened while going up a hill slowly and I bumped into the vehicle ahead of me. My vehicle had no damage, but the car in front of me had to get a new skid plate and my insurance doubled because of it. Since the incident in November 2024, my car has unintentionally accelerated intermittently. finally, April 2025 this happened my car started shaking jolted forward, engine revving, and then my check engine light came on then immediately contacted my local dealership and scheduled an appointment to get my car in. They have had my vehicle since then and have said it is not safe to give it back to me so I am currently driving a loaner vehicle.

The (PCS) Precollision System has been already set to LOW sensitivity, but every once in awhile when pulling in to oncoming traffic the vehicle would think there's still a car and just stalls for a few seconds (nonresponsive to acceleration pedal) leading to a dangerous occurrence where I could be hit by a vehicle because I've basically stopped in an active intersection. My vehicle is clean, so no dirt blocking the sensors, and I also own a 5th gen RAV4 without this issue.

The sunroof spontaneously exploded while in a closed position, not in use in any way, while driving in the rain on the highway. While driving at highway speed, a sudden “shotgun blast sound” occurred. The interior cover was closed. Wind noise became immediately apparent. Upon stopping to inspect, the exterior sunroof glass had shattered with the appearance it blew out from the inside, as the middle section was protruding upward. The sunroof has been used very minimally since purchasing the vehicle right at a year ago. There have been no issues with the sunroof. The vehicle is going to the dealership body shop in the next few days.

The brakes on my '23' Hybrid Toyota Sienna seem to have a sudden acceleration when braking at times. Typically, it happens when braking going down a hill or around a curve (at slower speeds) and sometimes when trying to come to a full stop. This has caused me to almost rear-end other vehicles on several occasions and has also caused me to go slightly beyond the stop sign, putting the nose of my car in the street. It is not reproducible at the dealership. It has happened since I drove it off the lot in July of 2023 and happens randomly and without warning. This is scary when you seem to be braking in plenty of time to keep safe distances and then you suddenly get propelled forward! It happens weekly and has happened weekly since purchase. In speaking with other owners, this sounds like a common issue.

intermittent brake issues, primarily characterized by a "brake release" sensation where the brakes momentarily disengage while slowing down, causing the vehicle to lurch forward unexpectedly, sometimes happening during turns or on uneven roads and downhills and even while stopping at any light or a normal road sometimes

The vehicle has a standard installation of a kick sensor for the rear hatch. I purchased the vehicle used and was able to start the vehicle and drive it for a period of time hoping to charge up the 12V battery. However, upon stopping the vehicle I could not restart it. Even after repeated jumpstart and driving the vehicle for over 45 minutes, the 12 V battery could not restart the car. I read about a similar issue with 2022 Toyota vehicles and so I followed the directions to disable the kick sensor. I then jumpstarted the car, drove it around and I found I could restart the car even after a short drive. I left the vehicle sitting in my driveway for two days and I could still restart the vehicle. I believe the 2023 Toyota sienna has the same issue as the 2022 model and the kick sensor needs to be replaced so it doesn’t drain the 12V battery when the sensor gets dirty. I live in the Midwest and this happened during January when there was snow and slush on the streets.

I purchased the car with 0 Miles. The tire pressure monitoring system would show an error every so often. Then go off immediately. But would never stay on long enough to get it diagnosed. It’s an issue and has be discussed on many forums as being a problem.

Car lunges forward 10ft or so intermittently when braking is applied. This is very dangerous given situations. Toyota dealer is given new car models under 36k miles a free fix, but they would charge high mileage cars a lot of money. I wish NHTSA demand Toyota provide free fix for this issue.

Air bags did not deploy during a major crash took place on 9-25-2024 the vehicle was a total loss.

When the vehicle hits a bump or you are turning while using the brakes, it feels like the brakes cut out for a moment and the vehicle surges further forward faster than you expect it to.

During braking, when almost stopped, the vehicle lunges forward so I have to press harder on the brake so I don’t hit the car in front of me. No potholes or irregularities in the pavement. It’s just a loss of brakes. It’s happened several times now.

When braking vehicle feels like it is being bumped from behind. Dealership says it is the vehicle switching from regenerative braking to normal breaking but it causes the car to lunge forward. It feels like the vehicle is going to lunge into oncoming traffic. I have to slam on the brakes to stop it. It’s very unsettling.

Passenger side sliding door randomly opens even when car is in the locked mode and when parked. It has happened 4 times. Toyota blames my chair lift and the mobility works blames Toyota. Service has not been able to recreate the problem since it is intermittent and has documented the complaint. However the only way to insure it doesn’t happen is to shut off the power to the doors making them difficult to open. This has only happened while parked but is a safety issue when not at home in the garage.

when approaching a red light (or any attempt to slow down) and I press on the brakes, some times the car starts to de-accelerate normally, and then a second or two later, de-acceleration stops for a brief moment. Eventually, the breaking system makes the car stop, but the distance it runs until total stop has definitely been compromised.... plus, the scare factor is concerning. This happens randomly.

The contact owns a 2023 Toyota Sienna Hybrid. The contact stated that while attempting to use the automatic sliding doors, the driver’s and passenger’s side sliding doors failed to close securely. The contact stated that the doors had to be forcefully closed. There was no warning light illuminated. The contact was concerned that the failure could cause an injury or death during the failure. The dealer was not contacted but the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 5,000.

While braking car will lunge forward regardless of speed. It happens several times a week since purchase of vehicle. I had a few near miss accidents where I almost collided with a vehicle in front of me. There is no warning lamp indicator for this event. Investigating on the internet gave me insight that this is a common problem not being addressed by Toyota.

When braking vehicle will accelerate for a brief 1-2 seconds then go back to braking, causing sudden jolts forward and increase distances needed to stop the vehicle, this was only noticed recently in the last 6 months and are at 20K miles as of July 2024, but is becoming more and more frequent, this happened twice on 7/8/2024

While slowing down to about 10mph to turn, brakes suddenly disengage and the car lurches forward. This happens every day, sometimes multiple times a day.

Problem with regenerative braking while braking. When coming to a stop the regenerative braking is engaged and sometimes the regenerative braking disengages before a complete stop causing a change in required braking force to stop the vehicle. This can cause a sudden jerk of the vehicle when having to press the brakes harder which can cause a whiplash movement.

-Car loss power for few seconds turning out from parking lot with an oncoming semi. Could have gotten smash. -Right sliding door randomly not fully closed. Dealer cannot repro neither issues and told me that they are charging $99 diagnose fee next time I bring the car in for the same reason. They did a 1x goodwill diagnose. Absolutely unacceptable for a car that is under warranty with 22k miles on it.

My husband and I bought a new Toyota Sienna Hybrid in September, 2023. I had a horrific accident on Wednesday, June 5 2024. The Sienna was in our garage and I went back in the house to get my cell phone I forgot. I had started the car, pressed the button to turn off the car but did not put the car in park as I should have. The car ended up going out of the garage and down the driveway- fortunately it hit a cement wall and almost totaled the car. We feel blessed that no one got hurt. I have never had anything like this happen before. I believe if this car was equipped like the gas powered cars we have always had driven this would not have happened. The key fob was around my neck. If I had to remove the key like in our Ford Transit Connect the car would have been in park-the car has to be in park to remove the key. I always take the key to prevent theft and being locked out. You cannot remove the key without the car being in park. I consider this a safety feature. These hybrid/electric cars have just the push button and have eliminated this safety feature. If the Sienna had had some kind of key to remove only when in park this could have avoided such a horrible accident. I had to chase after the Sienna going down the driveway- Fortunately there were no cars going by or people walking by. I consider myself an excellent driver- you can check my record. I know I need to just manually check the gear. With all the new technology there should be a way to assist the driver with avoiding this mishap- they could put in sensors that take the car out of gear if the driver’s seat becomes unoccupied. The same situation happened to our old neighbor about 5 years ago- her electric car rolled out of the garage and took down a brick wall. Please help with getting this matter rectified as more and more drivers are getting hybrid/all electric cars. As you can see we need this safety mechanism on all cars

My sunroof EXPLODED on 5/31/24 at 1:30 pm. I was driving about 55mph. There was no car in front of me or at my sides, and I was passing a rural grassy area. I did not see anyone or anything. It appears that the glass broke outwards. Fortunately, because it was 85-90 degrees, I had closed the shade about an hour earlier.

I turned right to park behind another car on the driveway and my car suddenly accelerated hitting the car in front. The collision was strong enough that the car that was hit then hit a barrier at the home.

Approximately 4-5 times it has felt like the brakes have slipped or let go for a very brief moment. I have either been braking over bumps, or braking going downhill. It is a slipping feeling, like is felt when briefly sliding on a patch of ice, or hydroplaning. It occurs for only a second or two. It has happened when conditions were dry.

I just read something about a recall affecting certain models of toyota vehicles under "unexpected movement." I have experience similar situation with my toyota sienna 2023 when in drive mode coming to a turn or turning into a driveway, slowly pressing on the brakes, the vehicle continues to unexpectedly move as I'm pressing the brakes, then it responds a few seconds after. It doesnt happen often, but it did happen maybe 5 times or less, ever since I got the car around summer time 2023. Luckily there were no cars in front of me during these few situation, it could've been an accident.

UNKNOWN. Randomly, while lightly braking, the vehicle will lunge forward. Does not always happen and unable to recreate it but has almost caused a few accidents. Van lunges forward for a second or so and then the brakes will re-catch or work again and the vehicle slows again. Scary. Have gone to toyota dealership but they insist nothing is wrong and they haven't heard of this issue. Forums with other Sienna hybrid owners state the same issue. Unsafe. Has happened multiple times, happened twice this last week.

Vehicles equipped with rear entertainment: when tv is folded down, Toyota failed to include a digital mirror to support the ability to see through the rear of the vehicle. When the entertainment system is folded down, the rear view mirror is inaccessible. Many reports are filed online describing the same issue by other owners. Recall should be made to fix the issue and have a digital mirror put in place.

As I slowly pulled into a parking spot, the car rapidly accelerated (as if I'd floored the accelerator - I didn't), jumping a curb. I slammed on the brakes trying to get it to stop. I ended up running into a parked car before I could get it to stop. I'm worried that it will do it again with someone in front of the car. There's nothing to inspect other than my broken fender from the collision. I don't know what component might have caused this. There were no warning lamps, messages, or other symptoms prior to this occurrence. The car is in good working order. Note: The claim form attached says "No driver", but that is incorrect. I was driving; there was no driver in the other vehicle (a parked car).

Our family bought a 2023 new Toyota Sienna [VIN [XXX] ] on July 7, 2023 paying the full price plus premium dealer markup from Elmore Toyota in Westminster, Orange County, California on January 7, 2023 and only received one keyfob for the 7 seater van. I was told that I would get a second keyfob within 2-3 weeks. I have constantly contacted Elmore Toyota and they have said that the keyfob has still not arrived as of December 5th, 2023. As we have three adult drivers using the vans and children who are seated in their car seats in the van, it is imperative that we get our second keyfob as soon as possible. If we were told that we would only get one keyfob and would have to wait over 5 months to get a second keyfob, we would not have bought this vehicle. It is a safety issue as the possibility exists that the single keyfob could be in the car when a child pushes a lock button for the van, there would be no second keyfob to free the trapped children. Please contact me to resolve this risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
