I do sympathize with those who have had this shocking and damaging experience. I do believe that such an occurrence, when genuine, should have been related to the electronics. This having said, there are some reservations about this article (http://www.pressofatlanticcity.com/news/top_three/article_5639c4f4-2f24-11df-b1- 7- 2-001cc4c002e0.html):
 
1. 52 fatalities are *possibly* connected to the problem of unintended acceleration. This means, according to the currently official statistics which I've seen somewhere, that either 8 or 12 are confirmed (I can't recall the exact figure), and the rest are still under investigation, if they are connected or not. Of those ~12, it is never said what was the cause of acceleration (electronics, mat, pedal, human error, acts of God, etc). The "drivers who have experienced the nightmare" are numerous, but by no means "countless".
 
2. Yes, this was in 2002. long before the current extensive media exposure. And, mind you, long before the electronic throttle control was used on that car, when the number of reports surged. So, we have a regular mechanic throttle, an elderly driver, and ... do you really believe in the mat or pedal explanations? Still there is room for electronics involvement, like cruise control (post #188), but what are the chances of a driver's error?

I think another factor is elevated RPMs during the warm-up cycle. In the Subaru threads we were talking about how PZEV models run at 2000rpm during warm-up.

Well, yes. My another car is 6-cyl Honda Accord. Every morning I start it cold and immediately pull out of my driveway, and it is pretty frightening when I am a bit distracted and don't remember to keep composure. Such a violent leap forward. But I am even more disturbed by "unintended deceleration" when that car downshifts during gentle braking at traffic lights. I even blamed the electronic brake assist at first. You know, poor workman always quarrels with his tools...

Edmunds is sponsoring a contest to get to the bottom of Toyota's UA problems. Your theory might just win the prize!

Hi to all. I worked as an electronics Test Program Development engineer for almost 30 years. Here are the important rules regarding fixing a failure:
Duplicate the failure, Analyze the real cause, develop & implement the fix and test it again on Many samples that have the Actual failure.
The unintended acceleration (UA) has happened in many lines of Toyota cars in various scenarios. The main difficult issue is the UA is NOT REPEATABLE. So, the right thing for Toyota and Edmund.com to do is collecting the cars that has MANY UAs happened. Then, there is a chance that the UA can be repeated and observed/analyzed. There are many possible causes for a failure. It is not a good idea to imagine a way that the UA can happen. It has to be the real/actual cause to verify and develop the specific solution.
 Toyota never shows the intention to buy back the defective vehicles for investigation & fix like I describe above. The same for Edmund.com to make the $1M prize worth its value.

No vehicle is perfect. Check on NHTSA's ODI database and there are complaints for all models.
 
The odds of this happening are extremely small. For my 2007 model year, there are about 3 times more complaints for the Odyssey, for instance.

How can we be sure that this fix is included in the 2011 version? Where did you read that?
 
Thank you...

In a perfect world your plan would work. What is the fair price do you suggest Toyota pay for these vehicles? Most people seems to think their vehicle is worth more than what it is actually worth(including me). Would you be happy if Toyota only offer you trade in value for your Toyota with SUA? What would stop everyone and their cousins who owns a Toyota and decide they want a new car/truck to begin to file bogus SUA claims if Toyota decide to offer full retail price to buy back these vehicles. Somethings are easier said than done.
I own a Toyota now and several Toyotas in the past, so do several of my in-laws, and my immediate family, and several of my neighbors. None of our car has SUA problems. My car now has 64K+ miles without issues except for what my kids broke in it. I believe Toyota is doing all they can. I just heard on the news today, NASA is also now being involved to try to figure this out(per Bloomberg TV).
Your best defense against this situation is to be knowledgeable and know how to shift your vehicle into Neutral if this ever happens and floor the brakes.
PS
I do not work for Toyota or any other car company. I do not own stock in Toyota.
