Toyota, the U.S. Government, and a host of private engineering firms are hard at work trying to pinpoint the cause of the reported cases of sudden acceleration that have resulted in the recall of millions of cars.
One step might be to listen to the Toyota owners who have actually experienced the problem. In recent days ConsumerAffairs.com has received an increasing number of these stories, some from consumers who experienced the incidents years ago but are only now coming forward.
Do they shed light on the problem? That's for an automotive engineer to decide. But some of the descriptions of the incidents are highly detailed and could be relevant.
"We have a 1995 Previa. In 2007, at about 93000 miles, it would accelerate on its own inside the city and on the freeway," S.J., of Michigan, told ConsumerAffairs.com this week. "It was very scary. We used to call it the rogue vehicle with a mind of its own."
S.J took the car to a dealer who replaced one of the car's two oxygen sensors. The sudden acceleration problem stopped.
"We have not had unintended acceleration for three years, S.J. said."
Oxygen sensor?
This week, thinking her Previa's problem might shed light on Toyota's current problem, she called her dealer and reminded him on the oxygen sensor fix.
"He said the problem they are discussing is different- we were not even on same page," she said.
And it should be noted that the Previa is not among the recalled Toyota models, though S.J. insists uncontrolled acceleration was a problem in her vehicle until the oxygen sensor was replaced.
Minneh of Arlington, Va., experienced a sudden acceleration incident Sunday in her 2006 Prius, so the facts are still fresh in her mind.
"I was doing a three point turn," she told ConsumerAffairs.com. "I went halfway into the parking spot, reversed to get a better angle and then engaged drive to go forward. The accelerator pedal just went loose, as if a spring had disengaged. There was no tension at all and the accelerator pedal just fell all the way down to the floor. The car lurched forward and accelerated."
Pressing the brake as hard as she could, Minneh said the car came to a stop and missed hitting the car in the next parking spot by inches. Nancy of Norlina, N.C.
Jean of Charlottesville, Va., reports similar behavior from the accelerator in her 2002 Toyota Camry.
On September 9, 2004, as I was approaching a busy intersection, as I started across 11 lanes of traffic at a green light, the accelerator left my foot and stuck to the floor," Jean said. "The brakes did not respond, and I could not downshift or use the emergency brake. It was necessary to go around traffic in the same direction by going up onto the curb. Because nursing homes were situated on both sides of the street with a senior center on the next corner, I could not risk losing power steering by turning off the ignition. I was unable to avoid shearing off a fire hydrant, a street sign, and two small trees by the time I decided to aim for a landscaped embankment at the end of one nursing home, hoping the elevation would stop the car when I turned off the ignition at impact."
Jean said she received only minor injuries and no one else was hurt, though the car caused considerable damage before crashing. Though the incident occurred five and a half years ago, she retains the memory of it in vivid detail.
15 seconds of terror
"The entire incident from the pedal's leaving my foot to impact probably took no more than 15 seconds, if that, Jean told ConsumerAffairs.com. "Toyota of North America did not respond to my letter and no local attorney would pursue the case; all I asked was replacement of my 2-year-old car with one OTHER than a Toyota, which I will never again trust."
Three other consumers mentioned their cars' cruise control when describing incidents of sudden acceleration.
"When placing my car into "cruise control" my car would accelerate until I would press on the brake out of fear to stop it," said Julie, of Worcester, Mass. "The acceleration reached speeds of 90 mph before I stopped it for the first time."
She said the same problem occurred three or four times after that. Carol of Colorado Springs, Colo., reports a similar problem.
"I purchased a 2001 Toyota Solara. The cruise control accelerates the vehicle when used. I've been unable to use that feature," she said.
Hamid of Nagasaki City, Japan, said cruise control played a role in stopping his car's sudden acceleration.
"I experienced unintended acceleration while driving on the Highway in my 2005 Toyota Prius whilst under cruise control on May 3, 2009," Hamid told ConsumerAffairs.com. "Breaking failed to slow down the vehicle as did initial cancellation of cruise control. I tried to decrease speed with cruise control stick by holding down. Switching off cruise control button and on again followed by repeated cancellation eventually worked."
In nearly every case, the consumers reporting the above incidents were driving older Toyotas not included in the current recall. But all insist they had the problem and no one at the time would listen.
But people are listening now, and it could be that the eyewitness testimony of people behind the wheel will prove useful in tracking down the source of the runaway cars.
