Toyota recalls and related issues: BusinessWeek-Media owes Toyota an apology

My 17-year-old cousin just got a 2010 Corolla XRS, and when I told her about the sticking accelerator recall, she told me that she has experienced this problem. I told her to give the dealer a call today.
She got the car 2 weeks ago.
I sure hope Toyota gets these accelerator problems resolved and that the FT86 DOES NOT come with drive-by-wire.
I repeat, NO DRIVE-BY-WIRE in the FT86.
If Toyota is serious about putting the FT86 on the market, I'm all for safety equipment like ABS and Traction Control that can be disabled. Make LSD available, have the car weigh around 2,500 pounds, and offer a stripped down model with the high performance motor. I need something to replace my aging S13.
I hope someone from Toyota Corporate reads this.

Someone w/the service manuals for any of the affected cars should be able to confirm whether there's a physical cable that moves connected to the throttle assembly vs. pedal w/sensor and a wire (that doesn't move) that carries signal.
(Even my former 02 Nissan Maxima had drive by wire. I had a recall related to it [for the pedal stopper]. One could push the pedal down and to the side, passing the plastic stopper, which the car thinks is a malfunction and triggers the check engine light and limp mode.)

More good info http://www.usatoday.com/money/autos/...tm?csp=usat.me. Be sure to read the rest of the story and not just my quotes.
The 09-10 Pontiac Vibe, twin of the Toyota Matrix and built at the Fremont, CA NUMMI plant is also affected.

Toyota says the potentially faulty pedals came from a CTS facility in Streetsville, Ontario.
...
Toyota says the problem appears to be due to premature wear of some mechanical parts in the CTS throttle assemblies. Hanson says that means new vehicles should be risk-free, at least long enough for Toyota to come up with a fix.
Throttle-pedal assemblies from Toyota's other supplier, Denso, are not all interchangeable, eliminating that as a quick-fix solution, Toyota says.

On cars with drive by wire, there is no moving cable attach to the throttle. The gas pedal is nothing more than a varible resistor with a wire connected to it. As most people who work with electronics knows, depending on the resistor's design, some varible resistor do get worn down and tends to sometimes get stunk when they are old. The brake pedal override recall should fix this problem.

That way, the chances of one wearing out are kept to minimum. Of course, that means producing enough of them to keep them in stock for a number of years.

After doing some more research, I realized that the newer cars today are using a Hall Effect throttle sensor instead of a varible resister. A Hall effect sensor works with a electromagnetic field. The distance between the magnet and the coil will increase or decrease the electromagnetic field which will determine the gas pedal's position. Since there are no parts in contact, there is no routine maintenance.

No parts in contact doesn't necessarily mean it won't go bad. My mom's E320 died at a light one day and wouldn't start again. When I did some research, I found that the crank position sensor is a huge problem on those engines. That sensor works with on magnetic fields and has no moving parts, yet has such a large failure rate.

mmarshall suggested to routinely replace them, not perform maintenance on them (although I'd be pretty pissed buying a car with the reputation of Toyota reliability knowing that I'd have to routinely replace a part that could have just been built better in the first place).

Crank sensors are also subject to extreme heat, oil, and whatever evilness is suspended in that oil (solvents, metal shavings, etc) and will therefore be more likely to fail than a hall sensor in the passenger compartment that never comes into contact with anything. It's not a very fair comparison.

It's not something that has to be done every few thousand miles, like oil changes/tire rotations, and Toyota could (?) cover it under free maintenence like some German carmakers do.
