2021 TOYOTA SIENNA Unknown Or Other Problems

I purchased a 2021 Toyota Sienna (VIN: [XXX] ) from an authorized Toyota dealer in June 2024. At the time of sale, I was assured that the open safety recall (23TA15) would be repaired soon. More than a year later, no remedy has been offered, leaving me and my family driving an unsafe vehicle. Toyota’s own phase schedule indicates repairs should already be available in Washington State, yet I have been repeatedly told no repair exists. This has caused serious safety concerns, financial hardship, and loss of trust. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving at 60 mph with all windows up, the sunroof spontaneously exploded. No vehicles near me, no debris in roadway, 70 degrees and sunny.

When breaking, mostly during downhill, the brakes feel like they simply “let go” for an instant. Most times this is very short and It feels like a typical downshift during breaking in an ICE car. However, last time it really gave me a lurch and I almost ended up falling off a cliff face. Many reports all over the internet but nothing from Toyota.

There has been several incidents when I step on the brakes and the vehicle seems to accelerate forward after what feels like an attempt to find the right gear when decelerating. This occurs infrequently but usually when decelerating along with an external factor. I was able to consistently replicate when I’m coming off the highway onto a service road then have to make quick turn at a corner. It feels as if the vehicle is trying to search for a gear and once it finds it there’s a momentarily acceleration forward.

In the 2-1/2 years than I have owned and driven this vehicle, I've had no problems. On Saturday, [XXX], driving home from a 80 mile trip, as I deaccelerated to make a left turn onto my street (speed was 7mph) I tapped the break pedal and the vehicle went bonkers! The Sienna veered right at a high rate of speed that the front end cleared the curb; the back end smashed into the curb flattening both rear tires and damaging the metal hubcaps; the vehicle speed tore off the bumper and both rear panels. I was able to steer the vehicle: missing a large 2-foot high tree stump; two other large trees; a 10-foot high solid fence at the yard back. I then drove down the sidewalk to the next intersection and was finally able to slow down. This entire time, my foot was on the break, but the vehicle would not stop. The Sienna is now at Faulkners Collision Center in Mechanicsburg with virtually no front end damage but colossal rear damage. The vehicle had 5-full maintenance checks since purchase. I was not told of any suspected problems and never received a vehicle recall. I could have been killed or may have killed others as there is a playground on the corner of this block.

I BELIEVE THE COMPUTER CAUSED THE PROBLEM. THE CAR IS AVAILABLE FOR INSPECTION AS PERSONNEL AT GETTEL TOYOTA IN PUNTA GORDA CLAIMED THEY COULDN'T TOUCH THE COMPUTER AND HAVE DONE NOTHING. Purchased Sienna in August 2021. In October at about 5:30 a.m. we were in the far left lane on a PA interstate, traffic came to a stop for construction. A delivery truck in front of us rolled backward a bit. When traffic started up again, our car would not go forward, only reverse. We tried "drive"--nothing--only had reverse. Finally, with cars whizzing around us, shut the engine off. Upon restarting, all gears were restored and we continued on to Boston. We were shaken by this event. Since then, we have had numerous incidents of the car not moving when I put it (mainly) into reverse. I had to shut the engine off--restart--and it went into gear. Latest incidents--first week February 2024--I pulled into a parking space at Englewood Hospital. After visiting my husband, came out, started the car, put it into reverse--NOTHING. Shut the car off--restarted it, and it was ok. Ten minutes later, I pulled off onto the shoulder to take a call from one of his doctors and--no gears. Shut off the engine, restarted it and it was ok. I'M WORRIED I'LL STOP FOR A TRAFFIC LIGHT ON ONE OF OUR 4 OR 6 LANE STREETS AND GET HIT BECAUSE OUR CAR WON'T GO INTO GEAR.

Recall: OCS Sensors May Short Circuit; 3TB15/23TA15 ; I am a owner of 2021 Sienna Hybrid (VIN [XXX] ) and was getting alert for the airbag and seat belt warning even when plugged in. I took it to a dealer in Sunnyvale California (Stevens Creek Toyota; 4202 Stevens Creek Blvd San Jose, CA 95129; 408-984-8833) and they are not recognizing the recall. I was charged a diagnostics fee of $ 899.93 and am being asked to pay $ 2000 to replace the car seat to fix the issues. Your advise is solicited. Best regards.

The sliding door on the passenger side opened while I was driving the vehicle. The door started out as closed. This is unsafe because I had a 6 yr old in the middle row of seats. I have not yet contacted the dealer or service center. The vehicle has not been inspected by anyone. There was no warning prior to the failure.

Pulling into paved parking spot on very slight uphill grade. Tried to apply brake pedal but car kept moving forward about 6ft over curb and crashed into cement wall creating slow speed impact damage to front end. Towed on flat bed to dealers lot. Tow truck driver noted brake seemed loose and had little resistance. Car still under warranty, 28.8k mi, All warranty required maintenance has been performed to date by Dealer. No prior accidents. Annunciation on screen after event saying "Parking Support Brake Malfunction Visit Your Dealer" Message has subsequently remained. Large number of same or similar annunciation messages over last 4 yrs reported on Toyota Nation web site. Messages indicate that TSB-019-19 may apply and/or DTC C13B0. However, Service Manager at Dealer has refused to investigate this and similar diagnostics to explain safety systems failure or otherwise repair under warranty agreement, unless we first sign a release for personal injury liability with Toyota legal department. Dealer has advised it is not safe to drive car in its present condition. Please note similar complaint sent a few days ago on this web site (no response so far) but there was an error in reported VIN so this is a resend

The breaks give out to a point where you run the risk of running into someone or something. We've visited Toyota 3 times now complaining of this issue yet they just state it's the regenerative breaks and how they operate. Although the breaking never got to this level of safety concern until we reached around 30,000 miles. I filed a complaint with Toyota that resulted in nothing being done. A couple examples would be sitting at a stop light and the breaks release almost causing us to run into the car in front of us. Pulling into daycare trying to stop while pulling into the parking spot and the breaks release. The last one is while going down hills the breaks seem to let go and the vehicle speeds up. It scared my wife so much that we actually sold the vehicle as Toyota deemed it safe. We loved the vehicle but can't risk the safety of our family.

When the sliding doors are left open for any purpose (cleaning, loading, unloading, sitting in a car, etc.) after approximately 60-minutes the sliding doors are disabled and cannot be closed. The key won't work. The button will not work. The overhead will not work. This poses a threat and danger to driver and passengers in possible and many times probable scenarios. If sitting the car at a park and there is a bee or bug swarm, you would be stung to death by the time you manually closed the doors that will only allow a few inches at a time. If there was a sudden weather change or flash flood. If there was an assailant approaching while you are sitting with your family for a bit with the doors open. Any number of things. I took it to Toyota and they wanted to charge me $150 plus for an assessment, to which I declined because this is their problem, not mine. My request is to have this fixed so the key will at least override the door shut off before someone gets hurt because of this. This has happened twice. I will enter the date it happened on the second time. It is Beechmont Toyota in Anderson Ohio that refused to service me.

After being parked for 4 hours the vehicle caught on fire. Burnt passengers rear corner and rear tailgate

The rear climate control unit has fallen out of the headliner several times. The climate control unit then dangles from the headliner, obscuring the vision through the rear view mirror and poses a potential safety risk as it could hit a passenger in the event of an accident or abrupt stop.

While slowing down from highway speed 55mph to about 30 mph preparing to turn right, I heard a huge explosion (sunroof). Thinking it was overhead, I slowly pulled back the sunscreen which blocks out the sun from the roof, realized it was full of broken glass and immediately closed it. This was a terrifying event and could of easily caused serious injury or worse. My dog was riding in a secured dog crate in the rear of the van. The van was taken to the dealership for investigation and repair. ( McDonald Toyota, Greeley, Co 80634) although the dealership is still investigating and agreed to follow up with Toyota, they are currently denying warranty.

Non

Good condition

Automatic sliding doors and tailgate opening by self when parked at home and 4-5 locations in Canada (during 1 week visit).Host in Canada (20 yr Volvo exec) independently observed and took car to Canadian dealer.Condition not duplicated at their dealership.However,they submitted report to Toyota Canada. Return to New York,took car to dealer Westbury Toyota on 8/30/22.Dealer observed car onite-no door opening found. 8/31/22-Westbury Toyota returned vehicle to lessee with the information that they are filing a pass case with Toyota Corporate and advised lessee to return to Westbury Toyota if problem recurs

Van was struck from behind. Van was still moving and was pushed to the left facing opposite direction in other lane. Van caught fire within a minute and became totally engulfed. Van was a total loss. Occupants were able to exit vehicle unharmed. Other car involved was also a total loss but did not catch on fire.

I have a Toyota van which has been converted to a handicapped vehicle by VMI. On June 14,2022, I took it to a local Toyota dealer to have the recall notice taken care of. (recall no. 22TA03). After an hour and a half I was told the dealer could not do the reprogramming because their computer would not communicate with my computer. They said they called three different dealers who could not tell them how to solve the problem. My selling dealer said to take it to another dealer but I haven't been able to do that yet. I believe any dealer should be able to perform recall reprogramming efforts.

My husband and I were pulling out of a parking lot, and needed to cross two lanes of south bound to end up in one of the two lanes of north bound traffic. Upon pulling out, the van stopped accelerating. We were stopped, sideways in the two lanes of southbound traffic. My husband checked to make sure the van was in drive, and it was. He tried accelerating a few times, and nothing happened. Finally, after about 10 seconds, the van began to accelerate once the accelerator was pressed again. He didn’t have to turn the van off or restart it or anything. This was absolutely terrifying. Before he pulled out, he checked to make sure there was no traffic coming from either side. Thankfully, the vehicles approaching noticed us sideways in the road and were able to slow down in time, as to not hit us. I know this vehicle has many safety features and when those go off, we’re given a warning whether it be a BRAKE warning across the dash, or other alerts. Not a single thing alerted us during this incident, and I have no idea why the van just stopped accelerating. The next day, Toyota inspected it (coincidentally we were told a Regional Toyota Manager was there that day and looked at it as well) and said the low voltage needed updated and that could possibly be the issue, but they weren’t sure. In looking at the paperwork from that day, they noted we said the battery wouldn’t hold a charge. We never said that. What we said was our van stopped accelerating as we were pulling out of a parking lot. This could have ended up very badly. We could have been hit. We have 3 children and I’m terrified this might happen again.

On 2 different quick occasions my gas pedal stopped responding to my foot commands. On one of those occasions I was crossing a street with a semi truck coming at me thinking I have enough clearance to make it across the street into the turning median. Luckily the gas pedal responded & I made it across with my heart beating 100mph thinking I was going to get hit really bad by the semi truck. It seems to happen when you’re in a situation where the pedal is rapidly pressed & depressed for anticipation of preforming a crossing. I didn’t go to the dealership because it would wasted time because they’re looking for error codes which the vehicle sister system mostly doesn’t provide because it thinks that it hasn’t caused an error. If the vehicle system is faulty then can it accurately log each incident without failure? Thank you.

1st. Brake sometimes get very stiff can’t press down and becomes normal after a few seconds or a few press on the brake pedal. (5 months) 2nd. A lot of wind noise coming from driver side windshield starting at 65mph. Complain to 2 dealers both said they test drove the same car but I don’t see any other Sienna around. They lied (1st day I took possession of the car) 3rd. The middle row seat rail are very hard to slide back and forth. (1st day)

While parked, the sunroof “exploded”. A loud sound was heard, and glass was heard hitting the roof of the vehicle, as if the glass exploded outwards.

We were driving approximately 50mph in the late afternoon (4:15pm MT) on a sunny day (about 60 degrees F). We were on a 2-lane road with farmland/field on both sides, with no debris on the road and we were not behind any other vehicles. The sunroof was fully closed (the shade/cover was open). The glass blew up and out, making the sound like a shotgun blast. There was no indication of problems prior to the moment of explosion - there were no noises, wind whistling, etc. or anything amiss. Large and small pieces and slivers of glass fell into the vehicle and we're guessing a lot of it flew behind the car into the road. Luckily we were not injured at all and there were not many other vehicles on the road immediately around us, but it was absolutely a huge safety risk to ourselves and others. We have 1 video and 2 photos from just after it happened. Our car insurance agent is coming to inspect in the next 24 hours. We immediately called the dealership where we bought the vehicle (brand new, 7 months ago) and were told the explosion was because a rock or other debris had hit the sunroof and to file a claim through our insurance. However we know nothing hit our vehicle. And the glass clearly blew upward - the glass remaining around the edges are angled UPWARD, not in toward the vehicle. This was not the result of debris - it was a fault in the manufacturing or materials.

I was on my way to the Doctor when the tire light went off on the dash. I was a few blocks from the Doctor and managed to make it there while the tire was losing air. When I drove in and parked the car in the emergency lane, I saw the tire was completely flat. I called the Toyota road service that was part of the car package, but it was nothing more than a recording that said I would be sent a text message link with a form to complete to get service. I did not bother after the recording warned that wait times were very long. I called AAA and a driver was sent to help within 30 minutes. First, he and I looked for a spare tire. Much to my surprise, there was no spare tire in the car. He used the foam package from my trunk to try to get the tire with enough air so that I could drive to Sterling McCall to replace the tire. However, the tire would not hold any air and remained flat. So, AAA sent out a tow truck to tow the vehicle back to Sterling McCall. This was a four-hour ordeal for me after a fifteen-minute visit to my Doctor. I am still recovering from another knee surgery and am walking with a cane. All of this could have been avoided had the car simply had a spare tire. A foam/air package is useless and should not be allowed to replace a spare tire set-up in a vehicle. This is a $45,000 car. I had no idea and Sterling McCall never once mentioned it when I leased the car. I am outraged that there is no regulation preventing car manufacturers from eliminating spare tires in vehicles. Most minivan owners are families with children and seniors (I am a 65 year old woman). These owners should not be put in the position that I was put in with this incident.

Factory installed rear entertainment system completely blocks vision of windshield mounted rear view mirror. Toyota has a video version of this rearview mirror but does not make it available to those who purchase models below the limited and platinum version of the Sienna. They do not disclose the ubstructed view that will occur when purchasing the vehicle with the rear entertainment system. In Canada, Toyota provides this mirror as part of the rear entertainment package. They are cutting corners in the U.S. at the expense of our safety. Please require a recall to fix this blatant safety issue that Toyota knowingly allowed to be permitted in family vehicles.

A lot Wind noise coming from driver side window and windshield at freeway speed. Report to Toyota service department but nothing was done to resolve the problem
