SERVICE BRAKES
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.

FUEL/PROPULSION SYSTEM
When accelerating, both from a stop and/or at speed, there is a definite hesitation. When gas pedal is pressed down, there is a noticeable pause before acceleration begins. This causes safety issues especially when accelerating to merge with moving traffic. Have owned this van since Oct 2021, and it has always been an issue. Possible fuel filter problem. Have not reported issue to dealer. Currently under extended warranty.

The passenger side rear door unlocked and opened by itself in the middle of the night, no warning messages were given previously, doors were locked that night. Keys were not accidentally pressed on. It seems that others have had similar problems with Toyota Siennas in the past as well.

The driver's side passenger door power cable broke. We had to turn off the power to all of the mechanical doors. There may have been a recall on this awhile back. The cable could be seen outside of the vehicle. We since have tucked it out of the way.

On [XXX], I was driving down the highway in Grand Rapids, MI when the sunroof above me suddenly exploded for no apparent reason. Thank God I had the interior cover closed at the time or I would have been covered in glass while driving down the highway. I pulled over, took pictures, and called my insurance provider. They have given me a real runaround about getting it repairs, offering to cover less than 10% of the repair cost. Neither the dealership, nor the glass shop could offer any reasonable explanation of why it shattered. The insurance company adjusted the claim via photos. I am currently waiting for them to offer fair compensation so that I can get it repaired. Repair cost estimate is $1335. If this is a defect, as it appears from some online searching, it should be covered my the manufacturer. It appears multiple individual and class action suits exist.

When opening the rear hatch, it will not stay open and slams down if you let it go. Incredibly dangerous. I turned of the power doors and it still happens. I'm planning to take it to the dealership tomorrow.

VISIBILITY/WIPER
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.

UNKNOWN OR OTHER
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).

ELECTRICAL SYSTEM
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)

Chest Clip, Buckle, Harness
I bought this carseat in March and began using it August 2nd for my infant who was born July 31st. The straps have slowly become an issue. We try so hard to tighten the straps but to no avail. This puts my child at risk if we were to get in accident as he is not secure and the straps are still loose. I did reach out to graco who informed me I had to do a warranty claim. I am not sure yet if thet plan to do anything in regaurds to this issue.

The rear hatch on our 2005 Toyota Sienna, after being opened, comes down almost immediately and can hit a person who is reaching into the back cargo area and cause injury. Other people have also reported this same dangerous malfunction online as far back as 2007.

SEATS
The third row passenger side split was stored and then put back up. Upon lifting the seats, pieces fell out (spring, washer, and screw) and the locking mechanism would not lock the seats into place. I am not sure how long these parts were loose, but it is a major safety hazard as the vehicle seat was not secured to the car as intended. We plan to to follow up with Toyota, but upon investigating, it seems that this is an issue for several 2011 Siennas. My Sienna was manufactured 4/2012. This is the smaller of the split seats, but out of an abundance of caution, we don't plan to use the 3rd row at all until a remedy is produced. Unfortunately, I saw only consumer complaints in regards to the 2011 3rd row seating issue and didn't see any solutions.

VISIBILITY/WIPER
The material used by Toyota to manufacture the dash is breaking down. Toyota is aware of this issue due to cracking and offered a limited extended warranty which I never received any notification (and many others did not per Toyota's chat forum). Cracking I can deal with. But now the material is continuing to break down and a thick sticky liquid is separating and rising to the surface creating a terrible sheen. When exposed to direct sunlight the visibility through the front windshield is dangerously low. The road basically disappears. I brought this to the attention of Toyota Brand Engagement Center on Nov. 10. 2023 (File #231110000552). I requested Toyota do the right thing, update their response policy, and authorize a dash replacement at a local Toyota dealership, but they refused based on the response policy they had established many years ago even after I explained the situation is not just cosmetic any longer. I explained the sudden loss of visibility and how incredibly dangerous and frightening it was, but they still refused to address the issue, so I am forced to bring this to your attention. Based on the Toyota's forum this is a widespread issue through several model years. Based on my experience I am confident there will be many accidents due to this manufacturing defect. Please investigate and request Toyota do the right thing to protect their customers.

ENGINE
Driving down highway noticed white smoke coming from car. Exited highway and warning light then came on saying engine oil low. Stopped van immediately on side of the road and had it towed. Appears the oil coolant line burst which is a known issue on these vehicles after google searching, but was never made aware. Always completed all recalls. Extremely dangerous especially with children in car.
