ENGINE, POWER TRAIN, UNKNOWN OR OTHER
As a result of the transmission cooler being a part of the radiator system, the transmission cooler ruptured while driving causing immediate loss of power and the engine to overheat. This malfunction also caused coolant and transmission oil to contaminate the engine compartment as well as the transmission. This is a major iengineering flaw and safety issue as I was on the interstate when it happened and was stranded on the side of the highway until help could be obtained.

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, SERVICE BRAKES
The vehicle stability control system randomly engages and activates the brakes without cause. This can happen on a gentle curve going under the speed limit. It is very scary and I am afraid it is going to cause an accident. Internet research shows many owners with this issue and no information on the cause or a fix

STEERING
I HAD THE VEHICLE INSPECTED BY PERSONAL MECHANIC BECAUSE THE STEERING WHEEL WOULD TIGHTEN AND THEN RELEASE WHENEVER TURNED TO RIGHT AND RELEASE ON LEFT TURN. THIS WOULD HAPPEN ON A REGULAR BASIS WHEN TURNING THE WHEEL. THE MECHANIC DID RECOMMEND THAT I CALLED THE MANUFACTURER TO CHECK IF THERE WAS ANY RECALL FOR THE PROBLEM. WHICH I DID. RESPOND WAS NO AND SO I EXPLAINED THE PROBLEM TO THE REPRESENTATIVE. THERE IS NOT A FAILURE OR INCIDENT EXCEPT THE STEERING WHEEL KEEPS ON TIGHTENING AND I'M JUST BEING CAUTIOUS. NO MANUFACTURER, POLICE, OR INSURANCE HAS INSPECTED IT BECAUSE THERE IS NO ACCIDENT. THANK GOD! JUST CONCERNED BECAUSE MY MECHANIC SAID IT IS SOMETHING FOR THE DEALERSHIP. SOMETHING TO DO POSSIBLY WITHIN THE STEERING COLUMN/CHANNEL COMPONENT. NOT SURE WHICH IS RIGHT, BUT TO CHECK FOR RECALL BY MANUFACTURER. I TOOK IT TO TIRE KINGDOM BUT SOMETHING ELSE WAS REPAIRED. SO I'M STILL HAVING TROUBLE WITH STEERING WHEEL STIFF TIGHTENING UP LIGHTLY. I WOULD FEEL IT TIGHTEN WHENEVER DRIVING 45 MILES OR MORE.

SERVICE BRAKES, STEERING, UNKNOWN OR OTHER
Slip light indicator comes on and alarm goes off, while anti-lock brakes engage. This is happening while I'm driving on the highway never in the city. The car starts pulling to the right sometimes almost pulling me off the road. The road conditions are completely normal and dry no gravel in it no reason whatsoever for the anti-lock brakes to start engaging. When this first started happening it only happens on curves while I was driving approximately 35 mph. After a couple of months it started happening also while I was driving approximately 70 miles an hour going straight on a dry road. It almost pulled me off into a ditch. The steering is affected I can barely steer but I have managed to keep the car on the road. This is now happening more frequently. I was almost pulled into another car to my right once. At first it was only every couple of months but now I had it happen twice in about a hundred mile trip. There's no way I can get a mechanic to have this happen because you can't predict when it will happen and many miles it won't happen. It is very very dangerous and I'm afraid to take my Toyota sienna on the highway now. After researching it I have found that many people are having this trouble with their Toyota Sienna's there needs to be a recall or a repair. Apparently Toyota mechanics have replaced all kinds of things in the Sienna's but nothing has fixed the problem.

FUEL/PROPULSION SYSTEM
The fuel line under the intake ruptured when I started my car on 2/21/23. The repair shop said they had never seen one fail like this. I do not have the parts. I was fortunate to be at home and that the engine wasn't hot when this happened so there was no fire. I had an issue starting the car ~ 1 month before that, but I don't know if the issue was fuel related. The car had been sitting for 1 week prior to that issue.

POWER TRAIN, ENGINE, FUEL/PROPULSION SYSTEM
The 2GR-FE engine on my Sienna has experienced a front timing cover leak. It's slowly leaking oil out of my vehicle and I'm afraid it will get worst over time. My vehicle has less than 100K miles and if the leak persists, I down want my vehicle breaking down and leaving me stranded.

SEAT BELTS
After a rain, water will leak into the driver and front passenger seatbelt coil housing. The front passenger seatbelt was not used in some time and mold developed with green and black stains all along the seatbelt. After it rained, the driver side seatbelt released about 1 cup of water when I pulled the seatbelt. With my wife as the passenger, she was conflicted about wearing the seatbelt while having mold pressed against her body, clothes, and breathing it in. The smell of mold is now present in the vehicle. This problem has been reproduced via online reports at SiennaChat.com. No warning lamps, messages or symptoms appeared prior, or during, this issue. I am in the process of reporting it to Toyota as soon as the next business day (Monday).

Due to poor design, air system intakes (eg under front seats) and outlets have not been protected by grilles, allowing intrusion of rodents into air system blower motor and heat box. I had rodent feces in my air filter system and blower motor and dead rodents in my heat box in Oct 2022 and has recurred in Feb 2023. Rodent intrusion in air system presents serious risk of respiratory illness to humans. Rodent infestation in vehicle can also cause startling to driver which presents an additional safety risk. Air system access should be protected by grilles at all inlet and outlet points.

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.
