While driving down the highway on the way to work the car suddenly went into idle. The car would not accelerate making it difficult to get it out of the way, luckily I was on the road in the early morning when traffic was sparse. Upon consulting my local Toyota dealer they stated it is the throttle body which is common in this motor. I have found that I am not the only person to have this issue and really think it should be investigated as this is an extreme safety issue and a recall should be issued.

I own a Scion xa, my dealer insists there is nothing wrong. The car lunges and suddenly accelerates and sometimes, it is hard to get it to slow back down the tachometer lunges past 4. I do not have floor mats. The dealer insists it is me not the car. This car accelerates suddenly and it has happened several times. Something is definitely wrong with this car. One time I couldn't control the speed at all nor would the brakes work. I am not making this up.

I took a 2006 Scion Tc in for a mechanic to investigate the cause of a "check engine" warning light. During his test drive, the vehicle reportedly unexpectedly accelerated and raced almost out of control. Per the mechanic, feedback from Toyota suggested the incidence was caused by a defective throttle body/sensor. According to the mechanic, the replacement part now offered by Toyota reflects significant modifications when compared to the original equipment.

In May 2007 I had a rear end accident with another car where my car would not stop when I put on the brake. The other car moved forward and my car still would not stop and hit it again. It finally stopped when I put it in park. It seemed to me the accelerator was overpowering the brake. It happened on two other occasions. I have taken it to the Toyota dealership twice for it to investigated, once after the accident and again last year. They could not duplicate it and told me the car uses drive by wire technology and it was impossible for what I am experiencing to be occurring. Now the service manager will not even return my calls. Calls to Toyota customer relations were met with you need to call Scion customer relations and when they transfer me the call disconnects. I own a 2006 Scion Tc. I took the drs. Side floor mat out last summer and now with all the press and Toyota saying there is nothing wrong with my car I am afraid to drive it. I owe more than it is worth, so I am finding difficulty in even replacing it.
