2. Prius reportedly accelerated while owner was pulling into garage

3. Owners report problems at stoplights as well as freeways

4. Some say problem seems to go away after vehicle is turned off, turned on

Says

"I was pulling into my garage. Suddenly my Toyota Prius accelerated out of control and drove into the wall of the garage damaging my nerves, the car and the wall." -- Janet, Texas Prius owner commenting to ConsumerAffairs.com

"They say it can't even be traded in." -- Janet

"I was almost stopped for a red light, my foot was on the brake (NOT on gas), the car was surging forward being held back by brakes. I quickly checked for anything under the accelerator including the floor mat, foot on the gas, or any other cause. All were negative." -- Dan, California Prius owner

"I called Toyota and talked to a sales person and explained this dangerous experience. He confirmed that he was familiar with the problem and also experienced this himself when driving one of the earlier models of the Prius." -- Karen, California Prius owner

Additional link to Consumer Affairs

The Toyota Product Communications office has not responded to several requests from ConsumerAffairs.Com to discuss the issue of unintended acceleration in the Prius.

Prius owners in the meantime continue to encounter incidents of unintended acceleration with the hybrid and the Japanese automaker seems unable to remedy the problem.

“I was pulling into my garage. Suddenly my Toyota Prius accelerated out of control and drove into the wall of the garage damaging my nerves, the car and the wall,” she told ConsumerAffairs.com.

Janet's husband thought his wife was the cause of the accident.

“My husband, thinking it was user error put the car in reverse and it accelerated again out of control,” she said.

Sorry, that doesn't happen twice like that with two different drivers without there being some defect.

Janet has reported the unintended acceleration problem to Toyota with no response.

On August 22, Dan in San Dimas, California reported a similar Prius problem.

“I was almost stopped for a red light, my foot was on the brake (NOT on gas), the car was surging forward being held back by brakes. I quickly checked for anything under the accelerator including the floor mat, foot on the gas, or any other cause. All were negative.”

Karen in Los Gatos, California has a 2007 Prius she has driven since December of 2006.

“After driving the car approximately 1,000 miles, Toyota Prius hybrid had an uninitiated full-throttle acceleration while driving on an expressway,” she told ConsumerAffairs.Com.

“Startled, I slammed on the brakes. The accelerator fought my braking as I pulled over and turned off the car, shocked and taking a deep breath,” Karen wrote us.

This is the problem withe electronics controlling everything. it's probably computer error of some kind that Toyota could easily fix if they'd admit there was a problem.

The longer Toyota turns away from the problem the bigger it will get. Why aren't they trying to address this issue? It seems like they just think it will go away by it self.

I thought this was a problem with earlier production units and it was fixed. :blink:

It has recurred again?

Tundras block's cracking, FJ's body's cracking, Honda Civics with wheels falling off, and now Priuses accelerating without notice. The apocalypse is upon us! :P

X2 to what FOG said.

only question about the interior... how easy would it be to hit the cruise on and the accelerate button if you're not paying attention?

here are some follow up questions.... Does cruise work in reverse? Does cruise work with the brakes on? Does cruise work at speeds under 25mph?

There are cases where Pruises accelerated unintentionally under these circumstances.

Looks like another sludging-style fiasco is on hand. Toyota will ignore the problem until voices become loud enough.

Tundra's BLOCKS ARE CRACKING? I have only heard of the camshafts...is this true? And as far I am concerned, a Prius' accellerating is unintentional!

Before blasting the evil Toyota any further, I would encourage you to read this:

http://www.usatoday.com/money/autos/2004-0...eleration_x.htm

The issue isn't the fact that the Prius might have an unintended acceleration problem. The problem is Toyota's response to the complaints and questions from the media.

If a Prius crashes into a tree in the forest due to a manufacturer defect, does Toyota even care?

I HAS THE SOLUTION!

(any homestarrunner fans?)

Design the car's computer to record both vehicle speed, and what controls are in use. Granted, it's not an instant solution, but it would be a very useful "black box" type of device that could be useful in many court cases, as well as figuring out these types of problems. If the computer says the car speed increased, and the brake was being depressed, and the gas pedal was not, then BOOM, you know there is a problem. If it says the car speed increased and the gas pedal was being pressed, and the driver swears they were pushing the brake, then the situation is a sensor-check away from strong evidence that the driver is an idiot.

I wonder how much of this info is already recorded... anyone know?

Interesting. I knew the Prius had a problem with intended acceleration. Kinda cool to read it also has a problem with the unintended kind.

My prius accelerated uncontrolably on the freeway? I'm laughing out loud. It's jerks like this (blaming user error on the car) that are going to get the NTSA to mandate black boxes in all our cars.

Sure it's fun to laugh at incompetent prius drivers, it won't be so funny when your insurance company won't pay out because it can see you were driving five over.

Not fair.

The Audi unintended acceleration fiasco was a farce. It nearly destroyed Audi in the U.S. market.

I actually remember it happening about 12 years ago. This lady was under the car trying to start it with a screwdriver, and when she did, the car rolled over her and dragged her about 15 feet. It took a team of guys, my father included, to lift the car off of her.
