1999 Toyota Sienna Owner Comments

problem #5

Nov 292010


  • 18,700 miles


On October 18, 2010 my 2009 Toyota Sienna dashboard vsc (variable skid control)/off track and check engine lights illuminated. I took my van in for service immediately. The dealership made repairs that were covered under warranty, and assured me that the van was safe to drive. On November 24, 2010, the same vsc/off track and check engine lights illuminated again. When I returned to my local dealership for service, I was informed that due to the thanksgiving holiday, the service department did not have availability until November 30, 2010. Service advisor assured me that my vehicle was safe to drive, as long as I stayed in town, and wasn't planning on taking the car on any long trips. However, I never got a chance to return my van to the dealership because on November 29, 2010 it started to make unusually loud noises and accelerated unexpectedly. Naturally, I attempted to stop by braking, but the brakes were not functioning at all. I tried again and again to brake, but to my disappointment the brake pedal did nothing, no matter how much I pumped it. Luckily, I was able to avoid hitting any pedestrians or cars by steering up the curb and into a lamppost. The van continued to accelerate uncontrollably until it finally came to rest on the steps of the county courthouse!

Driving on highway at 65 mph applied brakes and the pedal went to the floor -- no braking occurred. Happened once before on a city street. Seemingly random failure which the dealer says they have never heard of and have no knowledge of how to fix since it's intermittent. Nothing has been changed since everything is supposedly working correctly. The dealer wants to see the car again if the problem occurs again -- but the car might be totaled by then - -hopefully no one will be hurt.

Wheel cylinders replaced. I was told it was because I have not replaced the brake fluid yearly since owning the car.

All the above data is an estimate becuase we are waiting for copies of all maintenance and repair records from Toyota - - but we have had multiple problems with this vehicle including screeching brakes, left veer when driving, bad transmission (replaced twice),smog check failure due to oxygen sensor and/or engine problems, clunking noises in engine, a shuddering of vehicle when driving or braking. The car has been at dealers for as long as 3 weeks; dealer admits not knowing what is wrong. Failed
