Speed Control Linkage problems of the 2004 Toyota Camry

I own a 2004 Toyota Camry. It has a defective throttle body which has left my wife stranded and cost $1000 to fix from the dealer. This is a common problem and a few of my friends have had to pay twice to get this fixed. The other issue is there a defective part in the steering linkage that pops when you turn. This eventually leads to slop in the steering and it cause my to go in the ditch. This accident has given me a chronic back condition and prevented me from commissioning in the military. This issue is also known to be a problem with the Camrys but Toyota refuses to do anything about it.

I was stopped in traffic on ih-35 in austin due to an accident ahead. I had an opportunity to move to an exit lane and after moving to that lane, noticed a vehicle coming toward me at high speed. My way was clear to accelerate and I did so, pressing the accelerator about 1/2 the way down. Nothing happened and I pressed the accelerator the remainder to the floor. After a short time, the engine finally accelerated. Three days later, on Dec. 7, I took the car to the dealer and explained what had happened. After examining the car, the dealer called to explain that they had checked the car over and everthing was fine. He further explained that the 2004 Camry was equipped with a "drive-by-wire" accelerator. No one was injured, no damage was done, but I am concerned that this car will not respond quickly in a dangerous situation. Nor do I believe that this is an isolated situation. We had driven a demonstrator, a 4 cylinder Camry, about six months before we purchased ours. My wife was driving and pressed hard on the accelerator to get it to move up an entrance ramp and it also did not respond. At that time, I didn't place any significance to the car not responding, thinking my wife wasn't attempting to accelerate a quickly as she insisted.
