I own a 2006 Toyota Sienna le with only 26500 miles on it. I was driving my car on the highway doing 45 miles per hour on a dry pavement on Tuesday 09/03/2019 around 6:40 pm and at a sudden moment the vsc light started flashing, warning sound came on, the car applied the brakes on its own hard until it fully stopped, and the engine shut off by itself, which almost got me into an accident. I contacted Toyota and they told me that I have to pay for the dealer to get the car diagnosed for this safety issue, they transferred me to hudson Toyota and they confirmed that I have to pay for it despite that I had my car to the dealer recently for two recalls and they checked the car and gave me a report that everything in the car was good. I have looked online and I found a lot of Toyota Sienna owners from this model complaining about it and youtube videos documenting it, this link shows a Toyota Sienna owner documenting on video the same problem (https://youtu.be/sy9A8shj0xg) which happened with him 20 times in the course of 90 minuets and the dealer could not find what was wrong with his car. This issue should be fixed under a recall by Toyota because the car should not be able to apply the brake on its own randomly on the highway.

The brakes suddenly activate with the vsc trac lights and alarm going off, on the slightest turns and while going downhill. I hate having my wife and kids drive this van like this.

- Pacific Grove, CA, USA

The transmission was damaged, the right side passenger side broke, the "brake" lights are on all the time.

- Gurabo, PR, USA

Antilock brake system (ABS) warning light and parking brake light are on simultaneously, at all times once car is started. Issue was diagnosed as faulty ABS control module requiring replacement. Vehicle has never been in an accident, and to the best of my knowledge, has never even required that the ABS be utilized.

- Woodland Hills, CA, USA

The van has several times, without warning, applied the brakes while a light comes on the dashboard and a beeping sound is heard. The last time it happened my wife was merging into traffic and it caused a dangerous situation. I have researched and found this to be some sort of traction control system malfunctioning. It seems to have happened to many people, and many people complain it can potentially cause a life threatening situation. This problem has came on while normal driving or in my wife's case while accelerating to merge into traffic.

- Myrtle Beach, SC, USA

Traction control has randomly engaged 4 times in the past week, at speeds as low 35 mph and on the highway at 65 mph. Pavement was dry and we were driving straight, not turning. Braking is applied causing temporary loss of speed and pulling steering to one side for about 1-2 seconds. Control returns and trac control light continues to blink. Does not result in an error code.

- Marietta, GA, USA

When driving the vehicle regardless of speed or driving condition the traction control system randomly activates (it is always when going around a curve, but road conditions are dry, speed could be 70 or could be 20, there is no loss of control by me as a driver). This causes the car to abruptly brake. The computer system shows no issues when the dealer looks at it. When I deactivate the traction control system using the button the van will still beep loudly indicating a loss of traction control. It will also kick off the cruise control, but does not activate the automatic braking feature. This has been happening daily for 2 months with multiple visits to repair shops.

- Lawrence, KS, USA

I was driving 65 mph on the highway going straight on dry pavement and suddenly a buzzer sounded, the vsc light came on, and the steering wheel and brakes were taken over by the vsc system and the car started weaving out of control. I could not steer or break the car. The situation is unpredictable. It easily happened on curvy or bend road and has happened 3-4 times in this year. It is scary.

- Folsom, CA, USA

The vehicle was in motion. Driving up the mountain. When the traction control sensors went on and braked and began moving the steering wheel. Alarms where going off when no danger occurred. The next two hours the sensors would alarm. Did not matter how slow or fast we drove it would brake going up and down the hill. Took car to dealership and they stated that it was a yaw sensor malfunction part number 89180-45010. $900+ charge

A/C system has had problems since 2010, they replaced the belts & told me it was fine until the warranty expired.I have had recalls on all the doors, airbags &nav system replaced three times, 2013 A/C was replaced, 2016 A/C replaced again, & A/C is being replaced for a 3rd time along with two other recalls. Tire warnings are persistent. I've never worn out tires or brakes before, except with this vehicle at a rate of every 25,000 miles. (4times td)

- Atlanta, GA, USA

While driving the stability warning light comes on, starts beeping loudly and my brakes and steering wheel lock up. This has happened multiple times on the freeway, on freeway entrances with a slight turn and even while just driving straight. Each time, the weather was clear and the roads are dry. This happens whether I am driving at a slow speed entering a slight turn on the highway anywhere from 20 to 40 mph and has recently happened while driving about 50 mph on a dry highway just driving straight. The car has also began beeping and flashing the stability light without locking up the steering and brakes. I have almost cause a few accidents with cars almost rear ending my van and me almost sideswiping other cars while this is happening and I have no control of the car. This is frightening! I have had my struts replaced, right drive shaft, brakes, tires, alignment. The repair shops say they have not been able to duplicate this issue when they drive it. There does not appear to be a recall on anything to do with this which is shocking. I have a Sienna van so I can carry multiple people with me. I have my infant grandchild with me in this van each day as well as my teenage daughter. I have an appointment with maita Toyota tomorrow morning (1/25/18), we'll see what they say, but honestly, I feel Toyota needs to stand by their cars and fix this issue at no charge. There are complaints describing this exact issue all over the internet so it is not an isolated problem. This form asks for the date this happened below, I'll add todays date, but it has been going on for over a year.

- Sacramento, CA, USA

My slip indicator light comes on as I round turns and the engine seems to RPM down. This happens at normal speeds, on dry roads. Unable to drive on the highway, because when slip indicator light comes on, it also applies the front brakes at highway speeds. Other owners of Toyota Sienna are also having the same problem.

- North Plainfield, NJ, USA

Stability and/or traction controls (yaw ?) seemed to want to believe the vehicle was in an understeer -- causing the vehicle to want to brake automatically, sounding a traction control alarm. On a bone - dry road !!!

This afternoon I entered the highway and was going about 60-65 mph when my car suddenly started accelerating on its own, I repeatedly depressed the brake, even standing on it in an attempt to slow the car. The car was making a revving sound and the brakes were doing nothing to slow the car, it just kept accelerating. Finally, the brakes seemed to engage, the revving stopped, and the car seemed normal again. I pulled off the highway and called aaa to have the car towed to mechanic. Car has about 105,000 miles on it and it's been very reliable up until now. I will report to Toyota and I will not drive this car again, much less let my children ride in it.

- Denver, CO, USA

The car's vehicle stability control (vsc) will activate unexpectedly, braking hard and causing temporary loss of control. There is also an audible alarm and the vsc light turns on. Occurs intermittently when driving between 30-50 mph, typically on a gentle curve like a freeway interchange. Has occurred as many as 9 times on a single drive, and has caused a couple near accidents. An internet search of online forums shows that this issue is common in Siennas after 100,000 miles. Thus far my Toyota dealer has claimed they are unable to reproduce the problem.
