Sudden Acceleration

Last week I was pulling into a parking spot in my 2010 Kia Forte with my foot on the brake and all of the sudden the car took off on me crashing into the retaining wall. Kia claims they have never heard of the issue and there isn't currently a recall. Has anyone else had this issue and if so do you know what caused it. The car is still under warranty and more than likely can be repaired (I am still awaiting a final answer from the body shop) however, I am afraid to drive it and I can't very well sell it to someone knowing this danger exists.

The first question usually asked is, "Is it possible you hit the gas instead of the brake pedal?" That was the case many times in the famous Audi 5000 unintended acceleration issue.

AFAIK KIA are not in play in the SUA (Sudden Unintended Acceleration) sweeps. Not to say something could not have happened. You were there, none of us were.
"Tin whiskers" (look it up, plenty on both sides of that argument) were suspected in the more recent Toyota SUA. A California CHIPS officer, who you'd think would be among the most-skilled drivers on the road, and several family died when he couldn't control speed in IIRC a loaner Avalon and the car took off at 120 MPH.

A Look Back at the Audi 5000 and Unintended Acceleration
Friday, March 14th, 2014 by Michael Barr

I was in high school in the late 1980’s when NHTSA (pronounced “nit-suh”), Transport Canada, and others studied complaints of unintended acceleration in Audi 5000 vehicles. Looking back on the Audi issues, and in light of my own recent role as an expert investigating complaints of unintended acceleration in Toyota vehicles, there appears to be a fundamental contradiction between the way that Audi’s problems are remembered now and what NHTSA had to say officially at the time.

Here’s an example from a pretty typical remembrance of what happened, from a 2007 article written “in defense of Audi”:

In 1989, after three years of study[], the National Highway Traffic Safety Administration (NHTSA) issued their report on Audi’s “sudden unintended acceleration problem.” NHTSA’s findings fully exonerated Audi… The report concluded that the Audi’s pedal placement was different enough from American cars’ normal set-up (closer to each other) to cause some drivers to mistakenly press the gas instead of the brake.

And here’s what NHTSA’s official Audi 5000 report actually concluded:

Some versions of Audi idle-stabilization system were prone to defects which resulted in excessive idle speeds and brief unanticipated accelerations of up to 0.3g. These accelerations could not be the sole cause of [long-duration unintended acceleration incidents], but might have triggered some [of the long-duration incidents] by startling the driver.”

Contrary to the modern article, NHTSA’s original report most certainly did not “fully exonerate” Audi. Similarly, though there were differences in pedal configuration compared to other cars, NHTSA seems to have concluded that the first thing that happened was a sudden unexpected surge of engine power that startled drivers and that the pedal misapplication sometimes followed that.

This sequence of, first, a throttle malfunction and, then, pedal confusion was summarized in a 2012 review study by NHTSA:

Once an unintended acceleration had begun, in the Audi 5000, due to a failure in the idle-stabilizer system (producing an initial acceleration of 0.3g), pedal misapplication resulting from panic, confusion, or unfamiliarity with the Audi 5000 contributed to the severity of the incident.

Manufacturing the Audi Scare

If you're the kind of driver who sometimes has trouble finding the brakes in your car, you should be driving an Audi. Last month, in 35 mph crash tests of an airbage-quipped Audi 100, the mannequin in the driver's seat suffered the lowest crash force ever recorded by the National Highway and Traffic Safety Administration, NHTSA, in this kind of test.

And yet, according to the Center for Auto Safety--a self-styled public interest organization that sells its research to plaintiffs' lawyers--the Audi 100's predecessor, the Audi 5000, was as deadly as the Audi 100 is safe. It exhibited "sudden acceleration," a fatal propensity to take off at full speed even as the terrified driver rammed the brake pedal to the floor.

CBS's "60 Minutes" ran a devastating expose of the Audi 5000. Audi customers fled. Lawyers cashed in. The American public was saved, yet again, from the perils of technology gone awry. Only one little noticed footnote remains at the end: There was nothing wrong with the car.

The Audi story is by now, dismally familiar. "Sudden acceleration" accidents occurred when the transmission was shifted out of "park." The driver always insisted he was standing on the brake, but after the crash the brakes always worked perfectly. A disproportionate number of accidents involved drivers new to the vehicle. When an idiot-proof shift was installed so that a driver could not shift out of park if his foot was on the accelerator, reports of sudden acceleration plummeted.

But a story to the effect that cars accelerate when drivers step on the accelerator doesn't boost television ratings or jury verdicts. And driver error is understandably hard to accept for a mother whose errant foot killed her sixyearold son. So with the help of such mothers, CAS and CBS knitted together a tissue of conjecture, insinuation and calumny. The car's cruise control was at fault. Or maybe the electronic idle. Or perhaps the transmission.

"60 Minutes," in one of journalism's most shameful hours, gave air time in November 1986 to a self-styled expert who drilled a hole in an Audi transmission and pumped in air at high pressure. Viewers didn't see the drill or the pump—just the doctored car blasting off like a rocket.

What I hadn't seen a lot of mention was the driver's position, if they used the left foot or the right foot on the brake, and if backing up was the driver looking over the left or right shoulder? Any of these can affect a foot slipping.

Good luck with this.
