Problems with 2004 Toyota Sienna SERVICE BRAKES, HYDRAULIC

2004 toyota sienna van has been having intermittent vsc. at 10-20 mph the anti-skid warning light will activate with warning beep and the anti-lock brakes will active and begin to stop the car. when the anti-lock brakes activate the car pulls violently to the right and is difficult to control. toyota issued a tsb br008-04 in november 2004 stating ''some customers may experience an intermittent vsc activation after starting the engine and driving straight from a stop position. this condition is always accompanied by the instrument panel vsc light and audible warning buzzer turning on at the same time. to prevent this condition, the steering angle sensor has been changed. this is an obvious recall malfunction. why was there not a recall? *tr

Tl*the contact owns a 2004 toyota sienna. while driving approximately 5 mph a slip control alarm began to sound and the rear brakes locked. during the failure a slip control light also began illuminating on the instrument panel. the vehicle was towed to an independent mechanic who stated that there was rust developing on a spindle near the front driver's side speed sensor. the front driver's side speed sensor was replaced and the rust was cleaned from the spindle. the failure continued to occur. the failure and current mileages were 94,900. the vin was unavailable.

I owe a 2004 toyota sienna. within the last 30 days i had to replace my brake master cylinder at my local toyota dealership (over $1500) due to a brake fluid leak which caused brake fluid to accumulate into the booster and into the engine (and the brake light to illuminate). this is a very similar to the problem which caused toyota to issue the recall that was announced on october 20th with the toyota highlander model. i feel the recall should be extended to the sienna model. i contacted toyota, and they will not offer any reimbursement or relief for me. *tr

I was driving 2004 toyota sienna xle awd, 109,000, with bridgestone rft snow tires. at 15-20 mph on dry pavement, i tried to stop quickly for a dog strolling in front of us. the van slightly slowed, the dog waddled out of the way and we came to a rolling, gradual stop with the brake pedal depressed fully to the floor. i hadn't time to pump brakes and i don't know if it would have mattered. the toyota dealer couldn't duplicate problem and said pads, etc; were good. has happened to me this one time only, but google search suggests others may have had this experience. thanks

1. events leading to the failure: my wife was traveling north on peebles rd in allison park, pa in our 2004 toyota, sienna. after my wife proceeded through the intersection with duncan avenue the driver of the vehicle in front of my wife suddenly stopped short and that person's brake lights did not come on. when my wife realized the situation she hit her brakes hard and the pedal went quickly to the floor providing no braking and resulting in my wife?s vehicle to hit the vehicle in front of her. while all vehicles were traveling well within the speed limit the damage was extensive as the vehicle in front of my wife was a ford explorer. 2. the failure, frequency, and consequences: i have tried to replicate this failure and can readily recreate it. in a safe environment i have tried to suddenly and dramatically hit the brakes and the pedal quickly goes right to the floor. some fairly limited braking does occur during these attempted re-creations but it seems to be too little and delayed. my wife's vehicle was significantly damaged requiring $7,083.61 in total repair cost (documentation ...

The vsc has activated multiple times on my van for no apparent reason. while driving at any speed and usually in a turn, the vsc light will flash, the warning beep will beep, and the abs brakes will automatically be applied and the engine will quickly decelerate. i have almost been rear-ended several times because the van will suddenly decide to decelerate. i have no control over when this happens and no control of the van when it does! *tr

2004 toyota sienna xle ltd. there were times when the gas pedal would get stuck at 60 mph or when i was turning on a long freeway on ramp going about 30-35, the van would accelerate when i did not want it to. *tr

When backing 2004 toyota sienna le van in driveway the brakes failed. the vehicle has 41,000 miles and has always been serviced by toyota. the brakes were checked at 34,388. the car has a higher idle (fuel consumption) so in the process of backing, the car was rolling. i put the car in reverse and did not touch the acelerator. the vehicle rolled and continued to pick up speed, since i was unable to stop the car. the brakes were applied around 3 times and then i opted to hit the retaining wall instead of going back into the a busy street with wife and children in the car. it was either pray for no coming traffic or run into the neighbors house and vehicles. we have not experienced any problems in the past. the dealership was unable to identify any root cause. we are concerned about the safety of the vehicle and wanted a complaint as a matter of record. in researching the incident in google this is not an isolated incident and there have been a few records of such cases with the sienna van ...

Driving our '04 sienna at about 30-40 mph in flow with traffic with about 30-40 yards of separation had to brake for suddenly stopping traffic in front when brake pedal went to the floor with shocking mushiness failing to stop in time resulting in totaling of our vehicle and significant damage to vehicle we struck. *tr

Tl*the contact owns a 2004 toyota sienna. while driving 40 mph, the contact depressed the brake pedal, but the vehicle did not stop. there were 30-40 yards between the contact's vehicle and the preceding vehicle. the brake pedal extended to the floorboard. the brakes grabbed momentarily, but then became "mushy." the contact crashed into the preceding vehicle and caused injuries to the occupant in the other vehicle. the passenger's seat belt did not engage properly, causing the passenger to strike the dashboard and sustain minor injuries. a police report was filed. the vehicle was destroyed and towed from the scene. the failure and current mileages were less than 55,000.

The car is used on an occasional basis. 34,000 miles in four years. it has suffered corrosion buildup on the rotors, so we have tried to use it at least twice a week, knowing that catastrophe can occur when the vehicle is not used with some regularity--especially in the cold weather. about two months ago, my wife complained of noise, and i told her it was due to corrosion buildup and that driving would remove the corrosion. then she abandoned the car a couple of days later when the brakes failed. the inner pad had work down to metal, and the metal backing slid out of place. my wife wound up braking on the caliper piston. i will replace the brake shoes and rotors, and must also replace a caliper if i cannot find the piston as a separate piece. estimate: $300, not counting the caliper, with me doing all the work. toyota would likely charge a little more than $1,000 for the job. the car has sat unused and unrepaired now for weeks for want of the cash for the parts. *tr

Our family is deeply troubled and worried about the safeness of our 2004 toyota sienna le-8 every time we use it on the road. our van has been having intermittent vsc, kicking which started early this year. first, it will hesitate to accelerate followed by vsc kicking then automatic braking engages then sudden pull of the steering to the left. the vsc keeps flashing and beeps continuously unless i slow down to around 20mph. i even showed the dealer copies of sienna owners complaints with similar problem and tsbs regarding yaw rate sensor and steering column sensor. but still could not fix or duplicate the problem. nothing was done to correct the problem and no parts replaced or repaired. *tr

2004 sienna, had to replace brake pads twice. brought vehicle in for 30,000 mile check, and was told that they were again 75% worn out and need to be replaced for the third time. also, had to replace all four tires at 18,000 miles. *ak

I own a 2004 toyota sienna i bought new that has had to have the brake pads replaced 3 times in 62,000 miles. the last 2 sets only lasted 17,000, but the factory ones lasted 27,000. it' was worn out rotors, and had to replace those twice. it wa sbecoming very expensive, and seemed to be a product default. no other mini van i drove had anything like this. *ak
