Sienna 6-cyl

  • 116,000 miles
On numerous occasions, (the first incident occurring November 2013 and most recent 6/23/2014), the stability//traction control system suddenly engaged. Most of the incidents occurred while on the freeway with speeds between 50-55 mph, usually on straightaway sections, sometimes during a gentle bank usually toward the right. On all occasions, the roads were dry and the driver was not applying the brakes at the time. Without warning, the brakes suddenly engage causing the van to feel like it was lunging forward and making it difficult to control the vehicle. A series of rapid beeps would occur and the traction sensor would illuminate. The entire episode would last for several seconds. During these episodes, the vehicle is difficult to control and passengers/other drivers are in danger.

Six times now driving at speeds between 30 and 60 mph my Toyota mini van's vehicle traction control has activated, brakes go on, pull me into another lane, all lights flashing, car beeping. It lasts anywhere from 3 seconds to 10 seconds. It is absolutely terrifying.

problem #3

Jul 032004


  • 77,000 miles
Vsc engages at highway speeds: Vehicle alarm sounds, brakes deploy abruptly and unexpectedly, steering pulls, accelerator goes dead (pulse races, adrenaline courses). First complained to dealer after four incidents in first 20K miles: Had online testimonials of yaw sensor, steering angle sensor and ECM replacements as possible remedies; dealer rebuffed my complaints, denying service to sensors, and suggested my tires had 'gone square'. I have lived with the condition for a total of seven years. The car now 'goes off' maybe three times per every 20 miles driven, unpredictably and always shockingly. My family refuses to ride in the car. I cannot sell it in good conscience, as the defects cannot be confirmed by the dealer (and apparently therefore do not exist), so there is no way for it to be 'made safe' for a succeeding owner. Its remaining $10K+ equity has been nullified by this defect.

At any speed the traction control/ABS system warning light activated causing the antilock breaks to start pumping and making it difficult to steer. This occurred three times during our trip, even at high speeds such as 55 mph, which could have easily caused a collision if someone was driving behind us. It also felt as if it was difficult to steer the vehicle. We brought the minivan to peruzzi Toyota in hatfield pa and explained the problem adding we had paid for an extended warranty, they said it was not covered under warranty. It was caused by battery drainage and that a sensor between the steering wheel and the column had to be recalibrated and we had to purchase a new battery. I find it suspicious and alarming that this safety concern could happen to a vehicle due to low battery - especially since there was no indication of low battery. There were no warning lights and all other vehicle operations functioned properly. Also, no doors were left open and no lights were left on, etc... in order to drain the battery. Even if the primary cause was the battery, the breaks should not become activated and the steering difficult while driving down the road at 50 mph with my family in the care. Considering the recent recall of Toyota vehicles, I'm concerned peruzzi Toyota might have given us false information.

Sienna 6-cyl

  • Automatic transmission
  • 68,000 miles
The contact owns a 2004 Toyota Sienna. While driving 20 mph, the contact noticed the traction control engaged causing the anti lock brakes to engage. The contact stopped the vehicle; however, when resuming regular functions he could not drive more than 5 mph without the traction control engaging. A local technician determined that the wheel speed sensor and reluctor rings were rusty which caused the anti lock brakes to activate, the vehicle was repaired at a cost of $87. The manufacturer stated that they where unaware of the issue and a complaint was taken. The failure mileage and current mileages were 68,000. Updated 6/01/09 updated 06/02/09.
