Unintended Acceleration Is Running Rampant

Recommended Posts

Here is another news item, and although it is not about a Corolla, it is relevant: http://www.leftlanen...-floor-mat.html

 

Read the whole article. The second half of it describes a tragedy in Dallas -- with a Toyota with its floor mats stored in the TRUNK.

 

I feel the problem is in the electronics, like Steve Wozniak said here: http://www.timesonli...icle7013116.ece

 

In my opinion, Toyota's testing equipment isn't able to detect the fault(s) because it isn't designed to detect it/them. It's like an autopsy where no poisons were found using their regular toxin screen -- but when they search for specific poisons, then they can detect them.

 

It may be a combination of ECU processes that is causing this. Some engineers have stated in other forums that they believe the phenomenon is what they call an SEU, or Single Event Upset, the definition of which can be found here: http://en.wikipedia.org/wiki/Single_event_upset

 

It's 41 degrees F outside, and I just finished washing my Corolla. I still like it, though I'm disappointed with Toyota. Can't blame the car, really.

Good reference on the SEU. This is why mission critical computers should have ECC RAM. No one but Toyota engineers know what RAM they use in their car computers. It would be fun to take it apart and analyze.

Yes, it would be fun.  I've been getting a lot of relevant information at http://www.thetruthaboutcars.com

 

 

Hear the latest? Now the 09-10 Corolla's electric power steering is a hot issue, with around 80 reports of wild behavior -- and now, 4cyl Camry's have something going on with a power steering pressure hose. Wow!
