Woz Cites "Scary" Prius Acceleration Software Problem
theodp writes "Speaking at Discovery Forum 2010, Apple co-founder Steve Wozniak went off topic and spoke about a 'very scary' problem with his 2010 Toyota Prius. 'I don't get upset and teed off at things in life, except computers that don't work right,' said Woz, who went on to explain he'd been trying to get through to Toyota and the National Highway Transportation Safety Administration for three months, but could not get anyone to explore an alleged software-related acceleration problem. 'I have a new model that didn't get recalled,' Steve said. 'This new model has an accelerator that goes wild but only under certain conditions of cruise control. And I can repeat it over and over and over again — safely.' Toyota said it investigates all complaints. 'We're in the business of investigating complaints, assessing problems and finding remedies,' said Toyota's John Hanson. 'After man-years of exhaustive testing we have not found any evidence of an electronic [software] problem that would have led to unwanted acceleration.'"
We recently discussed other problems Toyota has had with electronic acceleration systems.
Businesses lose the opportunity to obtain knowledgeable input, because their call centers are staffed by low labor-cost morons. The need to identify technically savvy callers and hand-off those calls to comparably competent staff members.
I have no great love for Wert and the Jalopniks, finding them to consistently side with the GOP on social issues and sidestep into political discourse way too much for a blog on cars.
/. If he calls bullshit on software design, it will get attention. Worse off, as Jalopnik shows on the bit on the Today show appearance by the Toyota CEO - they seem willing and ready to lie through their teeth about what was known, when it was known, and what their responses to the NTSB have been. Matt Lauer is sitting there with a copy of the NTSB report on his lap, saying they knew humidity was causing pedals to stick in 2007, and there is the Toyota CEO lying his ass off, saying only in October of 2009 was it brought to their attention. Toyota is recalling a shitload of Camrys and Corollas, and now Woz drops this bomb about Prius software design on them. It's time for the Hedge fund managers to make more money and short the hell out of Toyota.
However, they have been frontrunning this story and trying to lead the charge to push it up to the MSM.
Woz is Woz, he needs no introduction on
Note, in NTSB reports - many of these cars have had the brake pads TOTALLY burned through, indicating that once these cars took off on people, they COULD NOT stop. In the fatality cases, if the driver had forced the car into neutral (the linkage would have resisted, you would have needed to really muscle it) they could have saved themselves. Instead they rode the brake into an obstacle.
This is PR nightmare time for Toyota. It will make the Ford-Firestone debacle look like simple times.
woz said he could reproduce safely .. I bet it is the same isssue as : This poster op
"I can nudge my cruise control speed lever and my speed barely goes up, say from 80 to 81.I nudge at again and again, up to 83. Then I nudge it again and the car takes off, no speed limit. Nudging the cruise speed control lever down has no effect until I've done it about 10 times or more. By then my Prius is doing 97. It's scary because it's so wrong and so out of your normal control. I tested this over and over the night I observed it."
To play devil's advocate...
Woz's problem might be specific to his own car.
I had an issue with my Cadillac's throttle assembly 3 months after buying the car (new). It was a bad sensor.
At the time I didn't know what it was (throttle, fuel line, transmission, etc). I searched through the big forum where EVERYONE reports their CTS problems and I only found 1 guy with a similar (yet different) issue. There was no tech bulletin about it, no forum posts, etc. There were other common issues out there which I managed to avoid, but this one was my particular piece that was the issue.
In short: until the car's engine temp reached equilibrium, pressing the accelerator more than 1/2 way caused the engine to buck wildly. It was like I was alternating between flooring the gas pedal and taking my foot off every second. This made merging and and stop signs quite unsafe, and I was able to replicate it 100% of the time so long as the car was cooled down first.
I had to take it to the shop 3 flippin' times before they addressed it. The first few times they said "no problem, drive it until it's worse." I had to sit in the car with a tester and finally told him "xxxx it, just floor it." He flipped out and what the car did and called a tech from corporate to look at it.
So, it's possible he has an issue that's related to the Recall but not part of the same batch of issues. It's a long shot, but still possible.
Do NOT Fuck with the WOZ!
Just DON'T
It is not prudent.

As someone who has written a program I was sure was bug-free after repeated testing, only to have somebody who doesn't know jack about programming find a bug, I have to disagree; Woz is probably right.
Especially remembering about the Pinto gas tank; ten bucks to fix a deadly problem they kept secret. How do you know the manufacturer found nothing? I trust a corporation about as far as I can throw their headquarters building. I would not be surprised if it came out that there is a problem, the manufacturer knows about it, but it will cost ten bucks per car for a recall. They'll weigh cost of the possible lawsuits against the surety of the cost of the recall, and if the suits are cheaper, they're not going to care about people dying.
Corporations do NOT care about your safety unless it is monetarily profitable to them or a government forces them to.

You do NOT turn off the car - this could lock your wheel, preventing you from steering altogether. Whats more, you'll lose power brakes - you know - the things that will stop your car quickly. Instead:
Put the car in NEUTRAL. The engine will disengage.
Hit the brake HARD. Do not pump.
Steer the car off the road, and once its stopped, you can PARK it and turn off the engine.
Look at the poster's name, that IS woz.
Posts not to be taken literally. Almost everything is sarcasm.
If you have your cruise set to 65 and it drops you down to 50 to keep from rearending the guy in front of you in a work zone and, when he moves, your vehicle accelerates back up to 65 the problem is behind the wheel. There is no excuse for you running cruise in a work zone and allowing you vehicle to exceed the posted speedlimit.

Which only serves to reinforce the notion that it is, in fact, the same problem.

And he expresses an opinion.
Is he still wrong?
The New York Times reported that Toyota stopped selling their defective cars only after the NTSB "asked" them to do it.
That's not exactly "voluntary". The way DOT and CPSC recalls work is that first they ask the manufacturer to do a "voluntary" recall. If the manufacturer says no, they issue a mandatory recall notice.
About once a decade, some manufacturer is dumb enough to let things go that far. It means national TV coverage ("The National Transportation Safety Board today ordered the recall of all NNN model XXX cars.") It means that, instead of a obliquely worded letter from the manufacturer, every owner gets an official letter from the Government with words like "dangerous and defective product" in big black type. The manufacturer involved usually experiences a large, permanent drop in sales.
