We should point out that the "speed control issues" on the Fords was not an issue per se with the controller, but rather with brake fluid dripping on it and shorting it out, causing fires and other problems.
My F150 had that one recall (I think we had to take it in twice, due to a temporary fix and a permanent fix) and I don't think it's had any others. It's a 2002.
I just heard the Cobalts are likely to be recalled due to failures in the innovative electric power steering. Right now, it's just at the investigative level.
NOW, ABOUT THE ORIGINAL TOYOTA ALLEGED GAS PEDAL PROBLEM:
I mentioned above that Audi's problem was eventually shown to be driver error. Putting your big clod hoppers on the wrong pedal, in other words.
Here's a nifty little test to put you in doubt of all those who claim that the car took off without their being able to control it.
Find a nice open spot, like in an empty parking lot or some such thing.
Park your car at one end, so you have lots of open space in front of you.
Start the car. Put your left foot on the brake pedal.
Put the car in Drive. Keep your left foot on the brake pedal.
Hold the brake pedal down as hard as you can with your left foot. Put your right foot on the gas pedal. Look down to be sure you've done this right.
Now, continuing to hold the brake pedal down as hard as you can, push the accelerator to the floor.
What happens?
In most cars, the engine will rev up some. Probably to something like 2500 rpm. It won't rev up beyond that.
And the car won't move.
Don't do this for more than a few seconds. It will overheat the transmission pretty quickly, if you do.
Why did that happen?
Well, your torque converter has a "stall speed." That's the speed at which it will allow the engine to turn, without turning the tranmission at all. In most showroom cars, it's 1500-2500 rpm. In hot rods, it might be as much as 5,000 rpm.
But the basic point is that the brakes are more powerful than the engine, in most cars.
And, should you have a problem with unintended acceleration, the way to solve the problem is to turn off the engine. Do NOT put it in park, reverse, or anything else. Just turn it off and coast to the side of the road.
Wow. Isn't science fun?
