Toyota said on Monday it had found no evidence to support the driver’s account of a widely publicised “runaway” Prius incident in California that overshadowed the company’s attempts to restart sales after a punishing series of recalls.
US safety investigators said separately that they had yet to pinpoint any evidence to support or disprove the claim that a 2008 Prius sped out of control near San Diego a week ago.
National Highway Traffic Safety Administration engineers drove the hybrid in an effort to recreate the episode reported by the driver, James Sikes, but failed to do so, the agency said in its first statement on a hurried and high-profile analysis.
“We would caution people that our work continues and that we may never know exactly what happened with this car,” NHTSA said.
Sikes (61) had reported in a call to emergency telephone operators that his Prius was racing out of control for about 20 minutes before he could slow down the vehicle and bring it to a safe stop with coaching from a California Highway Patrol officer who pulled alongside him.
Highway patrol spokesperson Brian Pennings said on Monday that the initial findings of Toyota and NHTSA did not constitute sufficient grounds to reopen an inquiry into the incident.
“Up until now, they’ve presented no physical evidence that’s like a smoking gun to disprove Mr Sikes’ statement,” Pennings told Reuters. “We have to take Mr Sikes at his word until there’s evidence to discount his statement.”
Pennings added that observations of the highway patrol officer who came to Sikes aid supported his claim.
When the state trooper caught up with Sikes’ Prius on the freeway, the car was traveling at 144km/h with the brake lights illuminated and the smell of burning brakes in the air, he said.
Pennings said that even when Sikes managed to slow the car by following the officer’s instructions to apply the footbrakes and emergency brake simultaneously, the driver appeared to be “literally standing on the brakes”.
Had the brake override system been working correctly, as Toyota says it was, that “should have killed the engine”, Pennings said.
Toyota said it had found no evidence that Sikes had been applying the brake forcefully and said he should have been able to stop the Prius by doing so, or by shifting into neutral or turning off the electronic power switch.
The March 8 incident came at a crucial time for Toyota.
Although Toyota’s March US sales have been up sharply because of cash rebates and zero-percent financing offers, some analysts have said the long-term commercial damage from the carmaker’s safety crisis remains harder to assess.
Scrutiny of the Prius, a vehicle the carmaker considers its most important, has also raised the stakes for the carmaker in ongoing US investigations of unintended acceleration.
Toyota plans to cut output of the Prius by 10% starting this month due to a sales slowdown, a source with knowledge of the plans told Reuters.
The 2010 Prius was the subject of a February recall for braking problems, and the 2004 to 2009 model-year Prius hybrids were included in an October recall for loose floor mats.
But the San Diego case was the first to trigger a federal examination of the Prius for unintended acceleration, something US consumers have complained about in a range of other Toyota models, including its top-selling Camry.
‘The hunt for the ghost’
California police have said they had no reason to doubt Sikes based on the burning brakes in his car and observations of the officer who helped him.
Toyota, which convened a news conference in San Diego to question Sikes’ account of events, declined to comment directly on whether Sikes might have misled investigators.
But Toyota said an examination of his Prius showed that the car was being driven with the brakes lightly and repeatedly applied—about 250 times over the period of the incident.
The brake override in the Prius would have cut engine power to the vehicle had the driver applied “moderate to heavy” pressure on the brake pedal as Sikes had claimed, it said.
Sikes could not be reached for comment. The San Diego-based law firm representing him said it would not comment until NHTSA had completed its investigation.
Toyota has said it has not been able to identify a cause for cases of unintended acceleration consumers have reported beyond ill-fitting floor mats and sticky accelerator pedals. The carmaker has recalled more than six million vehicles in the United States for that pair of problems since October.
Commentators have focused on the prospect that drivers could be making mistakes—hitting the accelerator instead of the brake—or that Toyota vehicles could be subject to a software glitch or other problem that is hard to replicate.
Toyota said again on Monday that there is no evidence for that latter possibility—a hypothesis that some critics have dubbed “the ghost in the machine”.
“The hunt for the ghost seems to ignore or fly in the face of known facts,” Toyota spokesperson Mike Michels said outside a San Diego sports stadium where the carmaker demonstrated the safety systems on the Prius for reporters.
“There’s no evidence that the system heals itself mysteriously,” Michels said.
Kelley Blue Book analyst James Bell said Toyota needed to do more than discredit one report of unintended acceleration to reassure consumers. “Until they have a more definitive answer, the elephant stays in the room,” Bell said in an email.
Recalls hurting image
ALG, a Santa Barbara, Calif-based firm that tracks vehicle resale values, said Toyota’s recalls had damaged the brand. It said its survey of consumer attitudes showed Toyota had dropped to number six from number one in perceived quality.
In response to weaker demand, Toyota will probably need to extend aggressive discounts through June, ALG said.
Sikes had told police and reporters he was driving the car on a freeway when it unexpectedly surged forward and reached speeds exceeding 144km/h.
Two NHTSA investigators joined Toyota experts to examine his Prius, including an on-board diagnostic system designed to record information about the car’s various systems.
NHTSA has been criticised by Congress for not aggressively investigating complaints against Toyota.
Authorities believe floor mat problems in Toyota and Lexus vehicles are linked to five US crash deaths since 2007. Another 47 crash fatalities reports over the past decade have been reported due to unintended acceleration in Toyota vehicles, according to NHTSA.
There are 59 reports of fatalities linked to episodes of unintended acceleration for other carmakers over the same period, NHTSA says. - Reuters
