“Engine has sever oil consumption to where we are adding a quart or more every 1000 miles or so in between oil changes. Worries me to were I check every week just to make sure there is enough oil. I should not have to worry about that sort of thing. While driving om streets or highways, happens every where, as you shift at a certain RPM (about 1500-2500-3000 ect) the car will hesitate for a few seconds. We originally thought it was from the A/C since I bought the car in the summer time but once the A/C is off the car still hesitates. …”

“Head gasket leaking found 6 head bolts loose. Installed new head gasket set, new intake manifold. Paid 2000 dollars for repairs, now having problem with the engine. Makes loud noise and overheats. Mechanic and bar agent advised it was a manufacturing problem. Headbolts came loose again and now I need new engine. Previous to this my insurance had paid a total of 5000 dollars for some mechanical and body work. I have been without a vehicle for almost seven months now. Called toyota manufacture company they told me the only way they would inspect the vehicle would be if they charged me. …”

“My daughter was driving her 2006 Scion TC ( made by toyota ) and the throttle body started locking, making the car cut out ( this started around april 1st )and this continued for a few days until around april 5th and then the throttle body would lock completely and shut the car off while driving down the road and the real disturbing part is that the steering wheel would lock, and this happened not once not twice but three separate times. …”

“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.”
