Default Article From Seattle Times- Old but I have questions

Here is a link to an article I just found today. It is from April 09 but I really respect MOST of the participants of this forum as you're highly educated with respect to Prius issues and such. The article annoyed me so much that I needed to take a Xanax after reading it!!

Seattle News - The Flip Side of the Perfect Prius - page 1

I've NEVER experienced any of these issues and I need to know what the heck is really going on.

I've never ever heard of such an incident that was qualified in any way.

I would wager that the majority of the claims are from people who screwed up bad and didn't want to own up to the fact or they had the "floor mat" issue. A few could even by propoganda and the incidents are not even real. I put nothing beyond tha capability of marketing people and their schemes nor the self-absorbed human society and their lack of accountability.

We've had one PC forum member who has experienced what appears to be a genuine unintended acceleraton event (actually more than one). It is worth reading the thread from the beginning.

The Seattle Weekly is now part of the same corporate chain as the Houston News, which originated this drivel without disclosing a conflict of interest. See the previous threads here in PC:

Actually a few months ago I had unintended acceleration but it was my fault. Here's what happened. I went to have the car washed and they took out the mats to clean and vacuum. They put the mats back in but did not mount them on the hinge. Since it was dark and I was in a rush, I figured I'd hook it myself the next day. Anyway, I forgot and I was driving on the turnpike and it happened. The car took off like a bat outta hell!! I knew right a way what it was. I grabbed the mat and pulled it back and the acceleration ceased. This brings me to another question. Is the braking on our cars solely based on electronics? if so, is it possible to have a braking issue IF there is a software glitch? Is there some type of redundancy system in the event there is a problem with the brakes?

So far as I know, the parking brake is mechanical.

Yes, there is redundancy in the braking system. There is a hydraulic system and a backup 12v power supply (charged capacitors) for the brake system. The hydraulic system works mostly operates at low speeds, but even at higher speeds hydraulic braking may be needed to assist what can be achieved with regen braking depending on how hard you need to brake.

If you want some reassurance that the hydraulic system would stop you, find a quiet road, take your speed up to say 30 mph, move the gear shift to Neutral, and press the brake pedal.

The braking system will failsafe to the friction brakes if the software or controllers fail.

From what I've gathered, it is likely that many of the 'unintended acceleration' events were likely floor mat related. It happened to me in a previous car once (that was not a Prius).
