My background is very similar to yours, and it smells the same way to me.
There have been some fairly detailed technical discussions about this on various automotive forums, which I've found pretty interesting. Personally, I'm betting that starting in 2012 or 2013, every drive by wire system - throttle, transmission, power steering, brakes, regenerative braking - is going to need a milspec-like compliance document before it ships.

That said, not all things are equal even now. There's a CR story circulating just under the radar that includes this bit (source):
CR says its analysis found the ratio of reports for experiencing such a problem on 2008 model-year vehicle from Toyota Motor Corporation is about one in nearly 50,000. Ford's reported risk is about one in nearly 65,000, while the reported risk for a General Motors vehicle is just one in 500,000
An order of magnitude is significant.

Please try and look beyond the Legal Speak. This problem has absolutely nothing to do with the pedal. It and several of the other problems reported by Ford, in their Chinese cars, the one the overrides the automatic steering, and the lose of brakes are all software problems. That bar and bronze bearing could not stick if you soaked it in salt brine for a week.

An interesting point was made on NPR news the other night. The delay in the Government pushing Toyota into reaction may have had something to do with the fact the the Congresswoman from the district in Ca. that houses Toyota's US Headquarters is a major stock holder in Toyota. But I am sure she was working in the best interest of her constituents, or was that her pocketbook.

You can blame the Tree Huggers for this one. The conversion to fly by wire was to manage the fuel system to ring out the last bit of MPG to meat Government standards.

This foolishness has gone so far that GM would only submit their cars, once equipped with Day Time Running Lights, for MPG testing if the Government allowed the testing to be done with out the lights on. That is working in the 3rd. or 4th decimal place. But that is where we are.

Interestingly, Ford brags about having Microsoft software in their cars.

Perhaps all you need to do when they start acting strange is pull over to the side of the road, shut them off, have everyone get out and close the doors, then have everyone open the doors, get back in, and restart the car. That's called the Ctrl-Alt-Del maneuver. Guess I'll wait for the new iTow.

Hi, at Ford, we would do the recall without the recall letter if your vehicle was listed on our computer for this recall and if we had the parts.

Hi, Henry Ford never wanted brakes on his cars to be controlled by a liquid; [hydraulic brake fluid] He insisted on keeping the mechanical metal rods system. Have you ever driven a Model A or similar car with mechanical brakes? I have, and it will scare the crap out of you. This is the future and it needs to be perfected.

Hi, In any repair business this would be considered a band-aid until a real fix is figuered out.

Hi, fly by wire saves fuel be gradually opening the throttle plates versus slamming them open instantly. First ones out by Ford, customers complained about lack of horse power. They had the same horse power as previous models, but won't burn rubber on take-off.

Hi, in the 90's some Fords would act-up and the only fix was to disconnect the battery for a few minutes, reconnect, and drive car normally for a few miles. [re-boot computer?]

Maybe Toyota will learn form this and put a battery cable disconnect switch in the driver's area because getting out and disconnecting during acceleration is not an option.

I am sure if anyone called Toyota HQ they would say just drive in and get it fixed. Now on the other hand the "Stealer" will fix Friends and Relatives first and with a shortage of pedals that is want is most likely happening.

I guess they'll be the first to find out the "pedal" fix didn't solve the software acceleration problem.

I don't get the bearing thing—never heard that before. I went to the same dealer and didn't see anyone I knew in the shop, so I talked to a new guy. The idea that it sticks a little before it sticks a lot has been publicized somewhere.

Did they tell you that you had to have a recall letter from Toyota before they'd do anything?

Howie, I don't use the lawyer thing unless I have to and then subtly because people resent it otherwise. They probably resent it anyway.

Gene
Yep they sure did. I thought about making one up myself and see if it flies. Thats what they seem to be doing to us. ( Making it up....)

If everything in that article is true, it would seem to me Toyota is in deep trouble. Well, maybe...depends on how many political favors they have to pull in.

Isn't that how they do it in Chicago?

Man, Thank God I have an old 75 dodge pickup. I can open the hood, climb in, and work on it. Only a few things can even go wrong with it. They all have. and I was able to tell what they were and fix them..

Man, and it was only $2000 new. I paid $2300 8 years ago. Has a 440 in it and will tow just about anything. Just can't fit the whole family in it.... and it only has 86,000 original miles

Plus it's built like a tank so I can hit deer, cows, elk, turkey etc. all day long and not worry about it. We have that wondering the roads around here.
