"Like your American Ford F-150 that's made in Mexico? That American vehicle? How about my Honda that's made in the USA?"

You mean assembled in Mexico dont you. There is a difference. The parts are shipped to Mexico when the final product is assembled. Like Chrysler's 300 assembled in Canada. Your Honda is assembled in the US. The Prius is assembled in Canada. What is funny is how Toyota switched to polymer batteries because polymer is a safer material. Does anyone know what kind of horrible chemicals go into making polymers as well as what horrible substances are created as byproducts when polymer is manufactured?

Who is going to save the planet from these yahoos?
 
what ever happened to the good old accelerator cable with a double spring return? Seems this drive by wire is only causing problems and making things needlessly more complicated. Not to mention ruining throttle response.
 
1. Woz was the founder, steve was the co-founder.
2. steve jobs was fired form the position for being a retard, and a useless asshole.
3. Woz designed their computers not steve.
4. Xerox created all the technology, apple/steve just stole it.
5. steve jobs stole money from woz and early employees when the company went IPO,
6. You still live with your parents, so stfu.
 
Just about one hour ago I was at the gym working out. CNN was on the overhead TV. CNN Wold Blitzer did a brief live interview of Steve Wozniak. When asked about the issue Wozniak managed to really confuse me. He didn't give simple answers.
 
"After man years of exhaustive testing we have not found any evidence of an electronic [software] problem that would have led to unwanted acceleration."

Ok I know he means many years, but oh really? So you've had a 2010 Toyota Prius tried and tested for many years? I find that hard to believe. Oh and just for the record, a software problem isn't the same thing as an electronic problem...whoever said that should get fired for stupidity.
 
[citation][nom]JofaMang[/nom]Automatic transmissions in low torque vehicles have ALWAYS had a problem with finding the right gear at certain speeds and changing gradients.[/citation]The Prius uses a CVT, not a traditional automatic. There are no gears for it to hunt for. If it accelerates past the speed he sets the cruise to, there is a problem. Now, it may only be a problem with HIS Prius, e.g. a bad component. But do a little research before you blame low torque and hunting gears. I don't like the Prius, but this has nothing to do with hunting for imaginary gears.
[citation][nom]lezavw90[/nom]He probably has the cruise control set at like 90mph trying to go up a 20% incline. And the poor little Prius is dropping gears and flooring it trying to maintain speed.[/citation]See above. Continuously variable transmission, no set-in-metal ratios, no gears to hunt, etc. He's probably got a bad module or else an overactive imagination.
[citation][nom]manitoublack[/nom]what ever happened to the good old accelerator cable with a double spring return? Seems this drive by wire is only causing problems and making things needlessly more complicated. Not to mention ruining throttle response.[/citation]Cables fail too, eventually, but otherwise I agree they were simple and reliable. But you've got the throttle response part backwards. Electronically actuated throttles improve throttle response if done properly. Why do you think they showed up on performance cars first in many cases? They improved the throttle response on LS-equipped Corvettes, and moved into more and more vehicles. They also simplify cruise control (no seperate module needed), eliminate the need for a seperate air bypass valve, improve fuel economy slightly, and allow ABS and traction control modules/software to modulate the throttle for better response to road conditions. Hmm, maybe that's where Toyota's problem lies.

However, not all drive by wire systems are created equal. If an electronic throttle seems slow to you, its probably either a poor design, or a fuel-efficiency-optimized setup, or if it has a conventional automatic transmission, it is taking too long to decide to downshift (lazy transmission). Most new drive by wire cars should have responsive throttles, especially performance cars. If drive by cable was faster, they'd still be using it in high performance cars at least.

[citation][nom]deadlockedworld[/nom]I bet it really pisses Steve jobs off that people still refer to Woz as "apple co-founder" especially when he does really crazy shit. Woz hasnt been part of apple for decades, and really should just be called by his name...[/citation]
Whether he is part of Apple now or not does not negate the fact he is the co-founder of Apple and always will be.
 
[citation][nom]falchard[/nom]Ford and GM aren't on the right foot. The only US car maker on the right foot is Chrysler because they went bankrupt. They won't be on the right foot until they make a car they can sell in the green. It doesn't matter how good the car is or how many they sell if they lose money on each car.[/citation]

Ford never took federal bailout money, or declared bankruptcy, and their new offerings are competing with overseas companies in terms of gas milage. In otherwords, they are not losing enough money to go into bankruptcy. The current economy is too harsh for car manufacturers to make real profits because people just aren't spending the money. Sales are down across the board. GM is also beginning to put out more efficient vehicles, and still has some killer performance cars for those of us who don't mind sacrificing efficiency for power. Give me an 8 with a catback, cam, blower, or give me death. Chrysler only really had the dodge line-up of the charger and the challenger, the ram was OK too, but other than that... DO NOT WANT. hopefully fiat can do something with them. Also, remember GM has many overseas brands... Holden made several cars that came to the states. The 04-06 GTO was one, and the Pontiac G8 was another. So while yes, GM is struggling in the States a bit, they do have companies overseas with things going well that can help them.

When you stomp on the gas pedal in a CVT, the engine will rev up first, then stay at a higher rev as the CVT changes its own ratios. Many CVTs, including the prius, also have set ratios to switch between, emulating a set gear automatic. If you are cruising at 65mph and encounter a grade to climb, the car will decide to drop the ratio AND add throttle to maintain velocity. If one is only looking at the tachometer, one might make the assumption that the engine is revving through the roof.

A Prius CVT can operate in full CVT, or emulated set ratios, depending on how the computer interprets the information coming from the sensors. A rapid enough climb while cruising, and the CVT will harshly lower the CVT ratio while simultaneously raising the throttle. CVTs are not just transmissions, the entire drivetrain is designed around the transmission, and they only work in conjunction with drive by wire throttles that can be controlled by the same onboard computer that runs the CVT.

He is describing a normal function of a CVT equipped prius, but has been taken off guard by the new version's higher torque and more responsive drivetrain. Combine that with his belief that he is the smartest person on the planet, and you get idiotic comments like this. There are savants that can calculate 10 digit x digit multiplications in there heads accuratly, but can't cook their own meals. Woz might be smart, but hes a fucking fool.
 
[citation][nom]milktea[/nom]Lucky I hold back on buying a Prius. I always had a strange feeling about it. And with news like that it looks like it would take me "Man Century" to buy a Toyota.[/citation]

My 1991 Lexus LS400 with 250,000 miles is still running strong and purrs like it did the day it rolled out of the assembly line. Top it off, I still get 22 - 27 Mpg Hwy and 18-21 City on my LS400's V8. Besides the minor wear and tear it is out lasting - 1991 GM Car, 1991 Any Other foreign Car cept maybe Honda, 1991 Ford anything, etc. A 19yrs old car....I'd say Toyota makes good quality cars.

Why would anyone drive a Prius except for saying "I am a green tree hugging earth loving person"? My wifes 2001 4 Cylinder Camry gets just as good gas mileage, cost less, won't have to worry about battery maintanence, etc. I'd rather drive my gas guzzlin Chevy Suburban 2500 anyday of the week vs the prius.

How does this sound? - "Hey kids lets go camping...load up the prius" or "Hey kids lets go fishing/boating....wait for me to hook up the 18 ft boat on the Prius" or for you young folks "Dude, my ride is sweat - look, 2009 prius with 20" rims and a 5 block radius booming stereo system!!"...you get where I am going with this?

 
I've heard all the complaints and even heard some of the accident reports read back, as well as the "I took my foot off the pedal and applied the brakes...then the rpms 'shot up' and the car took off" stories. In all honestly, the Toyota techs here have stated that they believe there's a software issue. Toyota doesn't want to admit that a software issue exists because the repair, on their end, gets more expensive to correct. If Wozniak, can in fact reproduce the problem repeatedly, it could either be a software issue or a faulty part. Simply being able to reproduce the problem doesn't mean a software problem....just a possibility. Mechanical problems, in most cases, can be reproduced repeatedly. Toyota has known of the problems for several years now, but up to this point had made no attempt to correct it. This means either the problem is a design issue, or they hoped it would just simply be accepted. Design flaws are a natural part of mass producing any consumer product....but to ignore complaints for several years shows improper management. Being that Wozniak's Prius is very dependent on software, it's extremely likely that his problem is software related....but in the case of other Toyota models, it could very well be a combination of software and design flaw.
 
I find it humorous that apple people and prius owners are both considered to be snobs...and this guy fits in both categories...just sayin.
 
do you really think that Toyota will admit that the problem is from their software? no not likely, just think of how many recalls will have to be done, it will be in the tens of millions.
 
Everyone seems to overlook the fact that Mr. Wozniak is/was a big Prius supporter. He even stated that he has many models of Prius...

It's not like he's just some dumb guy who doesn't even have a Prius, which describes most of the people posting irrelevant comments, and complaining just to be heard.
 
I haven an '06 Prius, and I have had no such problems. In fact, of all the cars involved in the recent recall, the Prius is NOT one of them. I think Apple is just looking for more press.

About 3-months ago, Toyota sent me a letter stating that they were investigating the possibility that the floor mats were causing the accelerator to stick, and people are saying that they were slow to investigate?

What I find interesting is that now that the faulty parts were traced to an American Company, everybody is still harping on Toyota. Toyota outsourced to an American company trying to help out America, and what do they get? Good old American crap. I would not be surprised if the part was made by a supplier that also supplies parts to US automakers.
