Toyota fixes arent working.

Audi can't seem to get it right, either. The "gas pedal position sensor" failed on my 2003 Audi A4, causing the same uncontrolled acceleration issue that all of the Toyota people have been experiencing. To add insult to injury, the warranty had just expired 1,000 miles ago so I got stuck with $150 repair bill to fix it.

Oh... and just like Toyota, Audi's customer relations department tried to blame it on the damn floor mats when I called to complain :|

Audi gets nothing right.

Well, in all fairness.. you just have to hold the button for a few seconds. But yeah, I agree with the sentiment.

I'd probably replace the button with a keyswitch.

few seconds = few hundred feet when the car is at highway speeds :/

Yes, you are correct. The DBW throttle pedal is essentially the same as the old pedal. You press it down, and a spring returns it to idle when you release pressure.

The DBW in my 06 Lincoln LS is perfectly fine. Helps that I flashed it, but it was still okay before.

I don't think folks understand what full throttle of a 300 HP car will do. Even at highway speeds it will sit you back in your seat somewhat and in 3-4 seconds you're doing 110.

That's the fix then. Mandate all cars to be limited to 100HP.

Don't go around saying things like that, somebody in congress might here you and think its a good idea.

Ummm...you listed brakes twice.

Anyway, a lot of this is going drive-by-wire in software. Off can be a problem with push-buttons. (Which is why they should only go with keys or key-like switches, but that's a different issue.) I think transmissions are going drive-by-wire too. They'd more-or-less have to in most hybrid designs.

So a mechanical brake link that disengages the clutch and prevents the electric motor in hybrids from accelerating sounds like a good idea to me.

Well it depends on the hybrid. Something like a Fusion Hybrid or Prius have single planetary gearsets/power-split transmission. So basically you have a forward 'gear', no true reverse(the computer feeds negative voltage to MG2, applys negative torque to the wheels so you then go backwards, if the battery is low the system can use MG1 to draw power from the ICE to help go backwards), and no true neutral so to speak(Achieved by turning the electric motors off. Under this condition, the planetary gear is stationary if you are stopped, if the vehicle wheels are turning, the ring gear will start to rotate, causing the sun gear to rotate as well, while MG1 freewheels so no power is dissipated.)

But I can tell you from driving my Fusion Hybrid that I can shift to neutral while accelerating, and that it already has a brake override, I can stand on the gas pedal while holding the brake and go no where. And I wouldn't worry about the MG1/MG2(aka electric motor) accelerating even when the system shunts max voltage to said electric motor it won't let you maintain it for more than 10 seconds max more or less to conserve the battery, I'm sure it's similar for Toyota hybrids.

One thing that makes me think it IS electronics is that none of the recalled cars were hybrid cars/trucks. I know for a fact it's a different ECU/PCU on the hybrids yet no recall...but thats just my personal opinion on the matter

I wonder how many salesmen are having to field questions about whether the model of car they are trying to sell has the brake override? Wonder if they are demoing it to buyers? For all makes, I mean.

I propose that congress bans automatic transmission for passenger cars. In a passenger car equipped with manual transmission, the car cannot downshift by itself in the event of a stuck accelerator pedal. The acceleration of the vehicles would be limited and there would be more time to react for the driver should the throttle becomes stuck, and therefore in light of these issues inherent to all passenger vehicles equipped with automatic transmissions, it is in the best interest of all Americans that automatic transmission in passenger cars be banned, except for circumstances where a driver is unable to operate a manual transmission vehicle due to disabilities.

Problem solved. Ban cars with automatics.

You're probably right. D:

Way to drive a perfectly good thread off-topic.

I'll be reviewing this with ZV later and handing out vacations as seen fit.
