POWER TRAIN
I have been notified by my Toyota dealership that the rear viscous coupler on my Sienna has failed and that the RAV4s have been recalled for this same part as a safety issue ( years ago). This part is a known manufacturing defect. Forums are wallpapered with complaints about this for years, I've already lodged a complaint with Toyota but they are doing nothing. Customers should not be on the hook for a $2500 repair that is a known manufacturing defect. The coupler recall should be extended to the Siennas!

The front passenger side bumper snap(s) comes undone, by air flow, as vehicle travels down the road - this causes further tearing of the supporting plastic frame. Local Toyota dealership says this initially was caused by a driver of the vehicle hitting a concrete curb. Note: Bottom of the bumper is only 8 inches from ground surface. The safety issue is: the bumper and its supporting plastic frame will eventually break and fall off vehicle while in transport. I have witnessed this several times on other vehicles (especially on Toyota's). Dealer compounds problem by saying entire bumper has to be replaced at high cost to customer. Customer delays repair (as I have). This causes further damage to the supporting plastic frame. I have gone from one snap to several snaps in duration. I sent Corporate Toyota a complaint - Essentially, they said they would not do anything .

SEAT BELTS
One day when we tried to buckle the driver's side seat belt, little pieces flew out of the receiver side and it will no longer buckle. We took it to the Toyota dealer in N Syracuse NY and were told it would be a cost of $212 to replace and that it would be a two-week wait for the part to come in. This means that the owner and her two young babies would have to drive in an unsafe car, ILLEGALLY for two weeks putting her life and the life of her children in danger. The Toyota dealer inspected the seat belt and confirmed it was a defect and had failed. I called Toyota customer service and was told that there were no recalls for this defect and they would take no responsibility for the dangerous situation or consequences because the car was no longer under warranty. In fact, this is a problem that has been affecting many owners as indicated by an online search. Also, the fact that the dealer has to wait two weeks to obtain the part indicates that this seatbelt has failed many owners and they have used up the supply. This should be a recall situation but Toyota will take no responsibility.

AIR BAGS
I own a 2019 Toyota Sienna with 52,200 kms. I bought it January 29, 2021. On Saturday, June 26, 2021, I was exiting the Quebec to Lévis ferry on the Lévis side. As I went up the metal ramp at 10-12 km/hr, ALL the airbags suddenly deployed with a great boom. We hit nothing. ALL The front and side airbags deployed. The front windshield was broken and one of the side windows was totally shattered. In fact it was not there any more. Pieces of broken glass flew all over the car and hit us. The vehicle filled up with smoke. On board was my wife and I and our two special needs sons. We had to hurriedly get them unstrapped and hand them to ferry workers on the outside. I was the only one injured. I received the airbag straight in my face and it hurt my neck. I have had a headache and neck ache ever since (today is June 29). I ignore the reason for which the airbags deployed. But I do know that Toyota has had to recall other 2019 Siennas for spontaneous deployment of their airbags. Maybe it is an airbag defect. My vehicle was still under warranty. The fire department and police were on the scene. The Levis Ferry director wrote a report. The Levis police report is LVS-210626-008. Thank you.

2008 Toyota Sienna. Driving down steep right turns, VSC light comes on, urgent beeping alarm and tires grip and grip vehicle brakes going 20-30+ mph on dry road. Very scary and dangerous, and has continues repeatedly over the past year on curvy right turns. Local mechanics don't know what is wrong with the vehicle. Many Sienna owners have similar problems listed on Carguru. https://www.cargurus.com/Cars/Discussion-c9152_ds656326 Please insist on a manufacturing recall for this vehicle. It is unsafe and could easily cause an accident. Thank you. Concerned original car owner.

Right side power sliding door will not open at all. It appears that the latch will not release. This started happening a few years ago and it was brought to a mechanic who disabled the power opener, and this appeared to have fixed it, but then the problem started to appear while manually trying to open the door. The same mechanic doesn't recall what he did to disable the power and would be able to open the door and would send us home, where in a couple days after driving it would happen again. It's now in a state where it can't be opened at all. And since this door is required to be open to access the spare tire, it makes it even more of a safety hazard!

AIR BAGS:SIDE/WINDOW:CURTAIN
When turning left in a busy intersection, our van was struck by another vehicle on the front passenger corner of the car. The strike occurred with my van going about 10 mph, the other car going about 45 mph. All of the airbags deployed. When the airbags deployed, the coverings on the lights came off and the small lightbulb and silver casing projected out, scratching my son's arm. Nothing in the vehicle should break or become a projectile when the airbags deploy. I am not certain on the last few questions.

STEERING, SERVICE BRAKES
Numerous times (too many to say), the traction control indicator sensor comes on & I am unable to control the car. Typically it lasts for 2-3 minutes and turns off. It does not depend on road conditions, weather, and or speed. I have taken the car to the repair shop and they have not been able to capture anything on the engine diagnostic system. No codes were found for them to troubleshoot this issue. I've seen this problem being reported on several posts. Yet the NHSTA has done NOTHING!! TOYOTA NEEDS TO BE HELD LIABLE FOR THIS ISSUE. WAKE UP NHSTA. MAKE OUR TAX DOLLARS WORK!!! This poses a huge risk to my family and other drivers, not to mention impact on budget.

POWER TRAIN
Loud Noise from the rear end, diagnosed to be a viscous coupler bearing malfunction by my mechanic. Total cost of repair is 2428 Dollars. In doing my research into this matter, this is a very common issue with my model Sienna. It is also common with same year Rav4 which a TSB was issued and covered by Toyota T-SB-0080-13. To cite a transmission mechanics who have experiences with the Rav4/Sienna rear differential issues. https://www.youtube.com/watch?v=r1vg2sbYL68 I hope you can help, this is a very large cost which is almost the price of the car in total. My family needs this car as we do not live in a city with very little public transportation available to us for utilize. The price of the repair will be a hardship on our family. I hope you can convince Toyota to step up and stand behind their product, to a very well known issue. Thank you for all you do.

EQUIPMENT:ELECTRICAL
A plug-in battery charger failed. You may inspect it. It got hot and smoked, and I suppose was a fire hazard. The problem has not been confirmed nor inspected. There were no symptoms of the problem before the failure. - - - - I used the automotive charger to charge a battery after a light had been on overnight, discharging the battery. I removed the battery from the vehicle because the terminals might have been corroded. When I first put the charger on the battery it indicated full and did not start to recharge it, so I used jumper cables to charge the discharged battery from a good battery in my car and left the charger at 10 amps on the good battery at the same time so that battery would not become discharged. I left it to sit, figuring it would take several hours at that setting, and after about 5 minutes I saw smoke. Both 12v wires were hot and insulation burned or melted off. There is damage to the car where the wires rested on the painted plastic bumper and a plastic bit near the battery, and of course the charger is useless. I wrote to the manufacturer on March 28 to make them aware, and ask how to avoid it in the future, and ask if it can be repaired. I have not heard back. - - - - The user manual for this product is at http://manuals.harborfreight.com/manuals/60000-60999/60653.pdf The current year model of this product is at https://www.harborfreight.com/10250a-12v-manual-charger-with-engine-start-60581.html - - - - The charger is sold by Harbor Freight Tools under the Cen-Tech brand.

Issue with traction (maybe called a VSC system-stability), when going up and down hills with slight curves, the wheels lock up and the vehicle slows down. Even when exiting a freeway ramp that is at a slight decline and curve. This started happening about 3 1/2 years ago, just once in a great blue moon. It started happening more frequently in the past year. Neither Carson or South Bay Toyota dealership could tell us why and could not find anything wrong after they inspected it. We took it to an independent service location and they could not find out why either. We looked it up online and apparently many Toyota Sienna owners are happing the same issue and no resolution. The VSC Trac light comes on when it happens and they goes away. It does not happen all the time. Safety issue for us, we can not really control the van when the wheels lock up and safety issues for all (us and others around us) is the fact that the van slows down and wheels lock up, which could cause someone to hit us.
