#ToyotaUnintendedAccelleration

Jim Sikes’ Prius high-speed dash to fame or infamy is a media hype-fest, with wild swings in sentiment from Toyota bashing to Sikes trashing. The rush to judgment is innately human, and Sikes certainly makes an easy target. But in the process, very little effort has been made to analyze what actually happened, or what might have actually happened, on the basis of the facts rather than Jim Sikes’ financial history and sexual proclivities.

Call it the ultimate of ironies. Yesterday afternoon I headed to the Toyota dealer in my 2005 Toyota Scion xB for the purpose of shooting photographs of various Toyota gas pedals to see why certain models seemed to have a higher rate of UA complaints to the NHTSA. In search of some intended acceleration, I headed up the up-hill I-105 connector on-ramp at Washington Street at full throttle. As I lifted my foot off the accelerator pedal, it stayed wide open…

The media and “celebrities” are making hay over the Toyota recall issue, desperate to find evidence of electronic and software gremlins. We’re adamant in stating that Toyota needs to change their software to give braking priority over a stuck pedal, and to replace the pedals, of course. And there may well be genuine software or electronic glitches out there, but we’d like to see solid evidence of them. Instead, we’re stuck listening to Steve Wozniak’s experience with a faulty cruise control on his Prius. It’s being spun as an example of Toyota’s electronics gremlins, creating confusion and scare-mongering. As if there wasn’t enough of that already.

Update: a portal to all of TTAC’s articles on the subject of Toyota gas pedals is here:

Toyota uses two different electronic gas pedal designs in its cars. The version built by CTS (lower) is the subject of a massive recall, and the 2.3 million units in affected Toyota cars are to be “fixed” by the insertion of a steel shim. This CTS design is also being modified for new Toyota production, currently suspended. To our knowledge, Toyotas built with the other design (by Denso, upper) are not subject to any recalls or NHTSA investigations,. We have spent the last two days tearing down both units, and familiarized ourselves with their designs, reviewed Toyota’s “shim fix”, and replicated the fix ourselves. Toyota’s planned fix will undoubtedly reduce the likelihood of sticky pedals in the short term, but after examining both units, we are convinced that the CTS unit is intrinsically a flawed design, and poses safety risks in the long term, even with the fix. The only right action for Toyota is to acknowledge the long history of problems with the CTS-type unit, and replace them all with the superior Denso or another pedal unit that lacks the intrinsic flaws of the CTS design.
