Rear liftgate opens, but then beeps as if closing, then does close without us wanting it to, slowly halfway, then slamming down after half-closed as if hydraulics or whatever holds up liftgate is failing. Anyone under door gets caught/slammed on. Yes, dealer rep has seen it happen at our local Toyota service center. The vehicle or component has not been inspected by the manufacturer, police, insurance representatives or others. There aren't any warning lamps, messages or other symptoms other than the usual beeping closing sound of the problem prior to the failure, and they first appeared Wednesday, May 1.

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.

I was driving and suddenly the 2017 Toyota Siena just lost all acceleration. The car no longer could move in gear. I put car into reverse or drive or any other gear and the vehicle would not move. The engine was on. The parking brake was not on. The transmission seems to have had a major malfunction. I had to have my car towed and my enitre family was stranded. I then looked up tranmission issues and found that 2017 Toyotas have a serious tranmission issue under -?? Certain 2017 to 2018 Model Year Toyota Sienna Certain 2017 to 2018 Model Year Toyota Highlander Coverage for UA80 Transmission Customer Support Program ZJC-??. I have approx 35000 miles on this vehicle and I bought it close to used from a Kingston Prestige Toyota dealership in New York State.

Brand new factory tires from the dealership only lasted 32k miles. Tires were replaced with the recommended tires for this vehicle and after 22k miles, there is significant wear where they will need to replaced again in the coming months. Each set of tires are 60k tires, and they are rotated and aligned religiously every 5k miles. However, each set of tires had excessive wear, no where near commensurate with the age of them. I will soon be on my third set of brand new tires when my van will only have roughly 58k miles on it. And per a general google search, it seems this is happening to a lot of Toyota Sienna owners. There needs to be an investigation as to why Siennas excessively wear their tires. I used to easily get around 60k miles with my tires on my previous vehicle, as I rotated and aligned them religiously to ensure their long life.

Today I had a crash and luckily walked away. I went down an embankment at speed into trees where the vehicle rolled and struck trees head on. All the vehicle airbags deployed and vehicle came to rest on the drivers side. Although there was electrical power and the engine still running none of the right side doors would open and neither would the rear hatch which was clear of obstruction! Had there been a fire I wouldn't be making this report! Doors need to be operable regardless of situation when none of them are jammed from an accident!

On 10/14/2021, as my wife was pulling into our attached garage, the vehicle suddenly accelerated, hitting a metal storage shelf located at the back wall of the garage. The impact of the crash caused the vehicle and the shelf to extensively damage the dry wall of that area of the garage, as well as to damage the pedestal supporting the house water heater, which resulted in the water heater detaching away from the wall and being destroyed. There was, of course, also major damage to the front bumper area of the vehicle. It is my contention that the cause of the accident lies in some component of the vehicle acceleration system. I believe this to be true because of two prior incidents which occurred within the month before this happened. On 09/16/2021, I was driving this vehicle and wanted to make a U-turn. I was traveling at approximately 10 MPH, but as I began the turn, suddenly, the vehicle accelerated to about 25 MPH, even though my foot was off the accelerator. My wife and granddaughter were in the vehicle at the time and both expressed alarm, somehow thinking I had purposely made this maneuver, which I assured them that I had not. Then, approximately 7-10 days later (I am unsure of the date), I was driving, alone, in this vehicle and went to make a left-hand turn. The vehicle again accelerated, even though I had removed my foot from the accelerator pedal and was applying the brakes. I estimate that as I began the turn, my speed was 10-15 MPH, but the vehicle accelerated to 25-30 MPH. I dismissed both of these prior incidents as not too important and attributed them to some unknown anomaly on the road. However, after the latest incident involving the damage to my garage and vehicle, research showed that several Toyota models and specifically the Sienna have had similar issues in the past. I am reporting this incident to Toyota for their evaluation, but wanted to make your agency aware, also.

When I'm driving my vehicle in a city street I get an alert on the instrument panel which says "trac off - check AWD system" and the service light turns on. I did not turn the trac off. When I turn the vehicle off and then back on, the service isn't on anymore and the message goes away. This has happened several times when I'm driving and the car stalls and loses speed and wants to shut off as I'm driving in a city street. For several minutes and the service light and the track and AWD light turn on and stay on for several hours. However, when I turn off the car the lights are still on but go away after some time. This has happened several times.

Toyota's AWD Siennas have a defective design in their axle hub causing premature tire wear which can lead to an accident. There is no way to align the rear wheels on the AWD versions. People expecting 50-60000 miles on their tires, will not get that amount of miles. Most will get 15-20000 at most. This is caused by the lack of wheel alignment features like the 2 wheel drive Sienna's have.

We were driving South on I-95 at 4 O'clock in the morning heading to vacation in myrtle beach. 2 hours into our drive at 6 am, driver stated that something was going on with the car. Felt like he was losing control of the car. I looked over and saw a gauge that read AWD brake override contact dealership. It started to slow down even more so he pulled off to the side of the road and when he did the car shook and vibrated and made a loud noise. When the car came to a stop smoke with seen coming from underneath the hood. And then a second later a flame shot out from underneath the hood. It all happened so quickly. I told everybody to get out of the car that the car was on fire. I grabbed my phone and my purse and jumped out and called 911. Fire engine showed up and put out the fire. The car was a total loss. The fire was super fast.

Since we bought the vehicle there has been a shaking and bang noise from the third set row and passager seat in second row and glove box. The arlington va dealer fixed it nine months later but the noise and shaking returned yesterday at the dealer in bowie Maryland the told us it was a normal characteristics issue just with our van no other complaints were issued. The tried to force us to take the van before it was fixed and took the retal car back which left us with no vehicle. My case number is 108011842. Just want it fixed not the rude unsatisfied service from the owner himself and tom the service manager.

Vehicle was taken in for normal service and was told that the tires were needing to be replaced at 20997 miles. Tires were rotated properly and vehicle was not driven outside of normal conditions. Bridgstone turanza EL400 run flat tires are original tires. Winter tires were installed at roughly 6000 miles and driven during the 2016 season winter until 11000 miles. Inside of Bridgestone tires are almost to cord. Toyota says that it the tire manufactures issue, and it could be an alignment issue yet the winter tires show no issue of wearing out of normal wear. They state that it is our problem, we need new tires. Have read a lot that others are seeing this same wear issue and even called another garage and was told that this a major issue with these tires concerning the premature wear on oee tires on this van.

A few weeks after we purchased our brand-new Toyota Sienna, the blind spot recognition technology stopped working. When I took the Sienna to a Toyota service center, a service advisor showed me that our Sienna had been side-swiped, unbeknownst to me, and that it was that exterior damage that compromised the blind spot recognition technology. When I arrived at the Toyota service center, a service advisor inspected the exterior of the vehicle to note any preexisting damage, and even that service advisor didn't notice the damage (this is how minor the exterior damage is: The person whose job it is to inspect the exterior of vehicles didn't notice the scratch that apparently knocked out an entire safety feature). It seems that the blind spot recognition technology was built to be extremely vulnerable. Exterior physical damage that is barely visible to the naked eye was enough to make the entire blind spot recognition technology break completely. Why isn't this feature better protected? furthermore, though only one component of the system is compromised, the entire system is unusable.
