When driving on the highway, the van will suddenly brake and the steering will lock up for about 10 seconds. It is truly frightening. It has happened many times, even with the anti-lock button off. I love this vehicle otherwise, but cannot drive it for safety reasons. And I feel bad selling it to anyone else because I don't want anyone to die! The scariest part when it's on a windy 2 lane road. It really becomes non responsive and also the brakes come on when you are going 60+ miles an hour! HELP! I DONT WANT TO DIE

I was driving on a dry road, going 70mph when my car began flashing the abs indicator and it began breaking and controlling my steering taking me into another lane. The car slowed my vehicle suddenly down to 60 mph and then went off like it never happened. I then had control. There was no reason for the car to do this. There was nothing in the road and luckily no one was to close to me or there would have been an accident. I almost over corrected due to the pulling of the steering and the breaking of the vehicle.

I was driving on dry road at approximately 65mph. There was a very slight curve in the road and the ABS system engaged without warning resulting in the van power immediately decreasing and fishtailing. Fortunately there was no one immediately behind or beside me or it would have resulted in a collision. I am afraid to use the vehicle. Used a code reader and there are no stored codes.

When driving the speed limit, going downhill, uphill, straight, around a curve, in the rain or dry weather, the vsc and slip/trac lights up, the abs system is activated / brakes engage. I loose complete control of the van. I can no longer steer or break. The breaks engage, but it causes the car to veer to the right. I have taken the car to the mechanic 5 times now and no codes show, even after he is able to the vehicle to repeat this behavior. It seems to happen a lot on off/on ramps. It happens mostly on highways, but it has happened on two lane roads. The vehicle is completely dangerous to drive. It has almost caused several accidents. I have replaced the Yaw sensors and had several alignments and this still happens. After a lot of research, we have found that this is actually really common in Toyota Sienna. People are saying that the bushings in the rack in pinion wear out and the entire rack and pinion system needs to be replaced. Some people have replaced the rack and pinion and claim that there is still a problem. But the majority say after the rack and pinion is replaced there is not further problems.

ABS pump stopped working. No warning. Brakes failed, ran into my garage. Took to local mechanic. Had to pump breaks to get it there or pay towing cost. Learned over $2000 for the part. It is know to go out he said and shouod gave been a recalled item...

- Endicott, NY, USA

ABS brake pump module. Went out causing accident. No warning. ABS lights came on. Took to shop. Draining battery, causing brakes to fail. Shouod be recalled due to no warning, complete brake failure, causing vehicle to be dangerous, not road worthy.

- Endicott, NY, USA

Brakes ABS not working. Can't find out why. Sometimes I have brakes, sometimes I don't. lighrs come on and off. Looked up recalls descriptions show tge same recalled issues but my car has zero recalls. Driving in traffic, brake pedal goes to the floor. No brakes. I got out of traffic and parked car in driveway. Pebdemic came. Now I need to find a way to fix it.

I've only had the van for 5 months and this problem has occurred over a dozen times, beginning with the day I bought it. And every time this problem has occurred I've been driving on dry roads. It usually happens when driving around a corner, anywhere from 35-65 mph, far. All of a sudden the traction control light starts beeping, the brakes engage on their own, and then engine makes a loud noise (likely downshifting itself). It's as though the vehicle thinks it is slipping, even though it is not, I drive very cautiously so it's not me flying around a corner super fast, it also happens when my partner drives the van as well. I finally took the van to a mechanic and they told me it was the steering angle sensor that was faulty and needed to be replaced, so I spent $900 to have it replaced. I've had the van back for less then 2 weeks and just tried to take it on a road trip, got about an hour from our house and it did it again 3 times in less then 15 minutes, again driving on dry pavement and when driving on a windy highway. It's terrifying when this happens especially because it always happens when we're going around a corner, it's very dangerous and scary. It seems to be happening with a lot of other Sienna's, even newer ones. This is an expensive problem that desperately needs to be addressed, someone is going to wreck and die from this if they haven't already.

Continuous issues with traction control system almost daily. Any time vehicle veers towards the right anti-slip indicator light, alarm sounds and ABS system activates. This happens almost daily, on dry roads, going downhill or on a curve, even while switching lanes now. This happens above 20 mph. Driving becomes stressful and worry-some when alarm begins to sound and dash light come on. Fear of losing control becomes great, fear for your passengers safety as well as other drivers safety becomes real. During the past 3 months there have been 5 separate incidents in which the vehicle has lost acceleration, pulls steering in one direction and sudden break lock occurs. 2 of which took place on the freeway on ramp at a speed of 35mph, 1 driving downhill, slightly towards the right, at a speed if 20mph and the last 2 while switching lanes, 35 mph. Vehicle began losing power and slowing instead of increasing speed. There are many complaints regarding this issue with many drivers in many areas. Why isn't this being investigated?

The traction control system is activating improperly. The vehicle's anti-slip indicator warning light illuminates; an alarm sounds; the ABS system activates; and the vehicle sometimes loses power. This happens on dry roads, most commonly either going downhill or else on a curve, even a mild one. This happens above 20 mph. When it happens, the combination of alerts and sensations are very startling to the driver, creating a dangerous situation. It has occurred while trying to accelerate to merge onto a highway. This was exceptionally dangerous as the vehicle began losing power and vehicles behind us almost hit us from behind as we were slowing instead of increasing speed. From my internet searches (including NHTSA complaints), this appears to be a recurring issue with this make/model/year range. This has been happening for the past 3 months. Our vehicle has approximately 135,000 miles on the odometer.

A couple of years ago, my 2005 Sienna's vsc warning lights, alarms and braking would come on while going around turns. My car had new tires, wheels were balanced and aligned. It's scary and dangerous when the brakes engage. I'm not going around sharp turns at high rates of speed. Dozens of other people have exactly the same experience, and when the brakes engage, it yanks the car hard, and has almost caused accidents to me and others. This happens to me on a regular basis. The only way to avoid it is to slow down to less than 40mph on some turns, which is dangerous when the speed limit is 65. Here's a link to the many other people's experience with this exact same thing. This is a liability and Toyota really needs to take action here.

Parking break does not engage until after several tries of engagement. And many times does not engage at all. Grade location of the vehicle does not matter (e.g. horizontal to >% deg). Attempts are only made while vehicle is in park. (it is not attempted while vehicle is in drive, reverse or neutral)

Since 7/2019 to now, 10/2019, I've had intermittent hard brake pedal. Letting up on the gas pedal, the van begins to stop right away. There's no rhyme or reason for the hard brake pedal, its affecting the front right wheel, and it smells bad. There's a vibration at times, and wobble. After the van sits for an hour, the brakes are fine until next time. Today, backing out of a parking spot, it was difficult to put the van in reverse, and letting off the brake, the van wouldn't roll back. I had to give it quite a bit of gas to get it to move. The van didn't want to go more than 10mph in a 35mph zone. All of this has happened since a new brake booster was installed. There is a new caliper on that right side, and both front brakes got new brake lines. The pads still have a lot of meat on them. I can drive the van just fine, then sometimes get back in the van later, 1 to 6 hours later, and the brake pedal is hard. It occurs when the van has been sitting all night and half the next day, or it can happen when I'm driving it. There is something wrong with the brakes on my 2005 Sienna. Nobody can figure it out.

When driving at any speed above 25 mph, the traction control light on the dashboard will come on, it will beep and the brake will engage without the driver pressing the brake pedal (these all happen at the same time). This in turn locks the brakes at times and the car veers to the right. There is no reason that we can figure out that this happens. It has happened many times and three days ago, it happened twice in one day. We have taken our vehicle to hendrick Toyota in wilmington nc and provided them a video where two owners took videos each time it happened in their vehicle. I also provided them with email discussions from two different web sites where owners were discussing the issue. We believe this should be a recall for Toyota.

I have a 2005 Toyota Sienna where the vsc system activated randomly and slowed our van down. When it first happened we thought that the van broke down because there was a beeping sound and it seemed like the brakes activated by itself. Kinda scared us because we were going around a turn at 60mph

- Houston, TX, USA

While driving at 55 mph highway speed and curving gently to the right, the vsc system on this minivan evidently picked up a false indication of a slip in the vehicle's traction. This caused the car to automatically apply the brakes on the left side, pulling the van's direction from right to left, and slow the car quickly from 55 to 35 mph, with vehicles behind me quickly closing in on the rear end. Within seconds the automatic braking ceased and I was able to reaccelerate back to normal highway driving speed. The engine was not stalled in the process.

- Eugene, OR, USA

ABS lights activate going at speeds from 15-60 on any type of curves then starts braking automatically. This situation has been going on for a while and as late as this past weekend (10 times) on highway 299 West from redding, ca. - eureka, ca. These sensors need to be recalled.

While driving around curves with dry pavement on highways and exit/entrance ramps at highway rates of speed (55-65 miles per hour or less) the anti-lock brake system engage, S causing the van to pulse and slow down unexpectedly. It disengages once the wheel straightens. We first tried to trouble shoot with our local mechanic with no success, prompting us to have our local Toyota service department attempt to diagnosis. Initially they said they were not able to diagnosis the problem or replicate it on a local highway (as it does not occur on every curve encountered) and were ready to send us home without any remedy. This was unacceptable. With our persistence they hooked it up to a computer and determined(without guaranteeing) it was the steering angel sensor and replaced it. Now without returning the van to us, they want us to replace the rack and pinion system for even more cost, again, without guaranteeing this will alleviate the problem. Per our reading up on this problem, we have found that this appears to be problem for other 2005 Toyota Sienna minivans.

The contact owns a 2005 Toyota Sienna. The contact stated that when the vehicle was shifted into reverse, the brake pedal was depressed but failed without warning. The vehicle rolled into thestreet. The contact had to continuously pump the brake pedal in order to stop the vehicle. The vehicle was not diagnosed nor repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 105,000.

While driving at approximately 40 mph and entering a left turn curve, the ABS and vsc lights activated and the vehcle lurched violently to the right then back to thge left. I was able to regain control after a few seconds, but during this time time I was not able to steer properly. The vehicle was taken to an independent service facility. The brakes and stability control were inspected. There were not any trouble codes stored. Examination of the wheel speed sensors revealed the right and left sensors were seized in their mounting brackets. We believe the sensors have rusted and have swollen. We had the ABS and vsc systems disconnected. The problem has not occurred since this was done. We are planning on replacing these sensor in the near future. This is a very serious condition and needs to be investigated.
