Recently reported UNKNOWN OR OTHER problems on 2004 Toyota Sienna

Unintended acceleration problem. two episodes, months apart, both at very low speed. was stopped behind two cars. two cars in front started up to go through intersection. i took my foot off the brake and moved it to the gas pedal. car started up normally. then a child pushed to crosswalk signal which started to flash. i moved my foot to the brake pedal, and the car started slowing down normally, but then the car suddenly lurched forward. both i and the passenger thought we had been rear-ended (but there was no car behind). it was a similar feeling to when the cruise control kicks in to accelerate, but no cruise control had been activated. i took my foot off the brake and slammed it back on the brake, and the car stopped. the previous episode had a similar series of events.

1) seatbelt twists and gets jammed in the guide near the retractor. seat belt pulls out, but then will not retract as it is wedged in the guide.this has happened numerous times, but now it is quite wedged. and unusable at the moment. 2) cable that pulls the side door open and closed has rusted and broken. this was subject to a toyota voluntary service campaign, but my problem started after the expiration of the service campaign.

While my vehicle is in motion on city streets and highways at speeds between 35 and 55 mph, on a straightaway and curve, the stability control light/and alarm comes on randomly. sometimes it's just the alarm that sounds, and sometimes the alarm sounds and the brakes activate and the minivan swerves. was the most frightening and dangerous experience ever with my young grandchildren riding with me. i actually had to pull over to the side of the road to calm myself. this has now happened on several occasions with today (7-24-19) being the latest experience.

Started having problem with the doors on the van the front door was the first problem with a failed door cheek causing the door not to be able to be opened had to force it open and remove the door cheek due to a weld that had broken away from the door is why it failed and the second was the power sliding door on the passenger side the door quite working and then when switched into the manual mode i was unable to get the door to close or it would close them come back open it took almost a hour to get it to close and stay closed. this being the car i transport my kids in that's a big safety issue to me knowing the door may not work or may not say closed while driving please help.

Traction control all of a sudden started turning on at every turn automatically making the car lock its brakes i'm pretty sure this is not the first you guys have heard of this

Developed multiple cracks on the dash around the airbags on passenger side. toyota is not covering this under warranty.

While driving on a highway, there was no sign of a falling/kicked up object, there was a sudden loud pop. almost as if a boulder hit the car. the sunroof was shattered in a million pieces, with no depression in the glass, indicating an explosion from the inside out. the only vehicle near, was a minimum of four car lengths in front of my car. fortunately, the sunroof was closed and no glass fell inside the car. however, after stopping and driving again, the glass broke apart and flew into the road.

Fyi: i am a nhtsa employee; i'm the lead engineer for fuel economy. i sit at w43-448. the driver side door panel pops out and gets stuck on the jamb on the floor and then you cannot open the door from inside. the main problem is in the way the handle is secured to the door steel.. it is a plastic piece inside and when it wears from pulling on it, it slips out. that puts tension on the plastic door clips around the edges that are supposed to hold the panel on. when the central anchor in the door handle goes, it causes the door to flex and the peripheral clips can't hold on so they pop out. when this happens, the door cannot open because the floor has a rise at the leading edge, and the panel has dropped below it, trapping the door. this happened with the original door, which was repair due to a deer running into the vehicle. it eventually had to spend over $1000 to get a new panel from toyota and now, less than a year after being installed, this panel has also failed. toyota knows that there ...

The rear door latch was recalled and replaced, it failed again, the rear door opens but then drops, it is a safety issue, i reported to toyota but they refuse to fix it again. serious safety issue stationary.

After multiple lawsuits filed, toyota issued an extended dashboard warranty to replace it until may 31, 2017. therefore, nhtsa was never involved with this case. since it was not a recall, there are still many affected toyota vehicle owners who were either not notified properly or learned about it too late. the problem occurred about 6 or 7 years later once they start driving; however, it was much later for those who do not drive their cars frequently or keeps the car in the garage or indoor parking facility as it has to do with the length of time exposed to the direct sunlight. not only is it a cosmetic and/or functional problem but also a driving hazard. as you can see from the uploaded picture, the shiny dashboard reflection is blocking the driver's view significantly when facing the sun direction. the problem exists in almost all toyota, lexus models produced between 2004 and 2011. i strongly urge that it should be a recall.

The driver side rear sliding door cable snapped and will no longer allow for the door to open

The front driver side door pops every time it opens and closes.

My rear hatch wont open with button up front or remote

Cable on automatic door have snapped. can not use the door.

The driver's side flap window detached from the metal frame, i cant get my state inspection to pass with this issue, i have my window taped. it is something a cannot fix, it is unbelievable that this could be happening. the fix is very expensive and i have no way to pay for this. if the window falls off completely can cause an accident. it happened when i was driving to work in the highway i suddenly heard as if my windows were open i looked thorugh my rear view mirror and the window was wide appart due to the wind but because it was still attached to the hinge and the shades were hooked to the glass it did not fall off completely.
