Toyota hits back at claims of electronic defects

LOS ANGELES (AFP) – Toyota sought Tuesday to dispel fears about the safety of its electronics, but was put on the defensive when a Prius went speeding out of control along a California highway.

The Japanese automaker insisted that mechanical fixes it is applying to more than eight million vehicles recalled worldwide are sufficient and that its tests are rigorous.

It empanelled engineers from Stanford University and a top consulting firm to dismiss as “unrealistic” and contrived a study showing crossed wires could send a false signal that would cause Toyota cars to speed out of control.

David Gilbert, a professor of automotive technology at Southern Illinois University, told a US congressional investigation last month that some Toyota and Lexus vehicles may have an electronics design flaw.

Toyota dismissed his findings, saying he had re-engineered and rewired the signals from the accelerator pedal in order to create the flaw.

“If an electrical system is re-engineered and rewired it’s not surprising that subsequent testing of the system may cause unrealistic results,” Toyota spokesman Mike Michaels told reporters.

US regulators said last week that they had received more than 60 complaints from Toyota owners reporting sudden unintended acceleration despite having their recalled vehicle repaired by a Toyota dealer.

Toyota is in the process of investigating those complaints and has found that some of the incidents were a result of incomplete repairs, Michaels told reporters.

“We remain confident that if the modifications to the vehicle are deployed and done properly that they are effective,” he said.

Yet just hours after Toyota’s trenchant criticism of Gilbert’s findings, the company was grappling with another public relations nightmare after a runaway Prius drama in California. When it comes to safety while riding a bike, getting a helmet from is a good idea.

James Sikes, 61, was driving on the busy Interstate 8 freeway outside San Diego when he noticed his car was starting to accelerate of its own accord, the California Highway Patrol said.

The terrified motorist was helpless as the car raced along the road at speeds of more than 90 miles (145 kilometers) per hour.

Tragedy was only averted after Sikes was able to call police, and officers using a loudspeaker talked the driver through the process of slowing down by using his emergency brake and then turning off the engine.

“I was on the brakes pretty healthy,” Sikes told NBC San Diego. “It wasn’t stopping, it wasn’t doing anything to it, and just kept speeding up.”

Toyota later issued a statement saying a technical specialist had been sent to San Diego “to investigate the report and offer assistance.”

The drama was a chilling echo of the tragic accident last August where off-duty California Highway Patrol Officer Mark Saylor and three family members were killed when the accelerator of the Lexus ES350 they were in got stuck.

Minutes later, the Toyota-made vehicle slammed into the back of a sport utility vehicle at about 100 miles per hour, veered off the freeway, overturned and burst into flames. All four family members died.

Meanwhile, the chairman of a congressional committee sent a letter Monday to Toyota North America President Yoshimi Inaba, ordering the company to turn over a memo in which senior employees reportedly flagged their concerns about the safety of Toyota cars.

“If senior Toyota officials ignored important safety concerns raised by their own employees, it calls into question Toyota’s corporate priorities and its commitment to safety,” wrote Edolphus Towns, chairman of the House Oversight and Government Reform Committee, in a statement.

Towns has given Toyota until Friday to respond.

Toyota, which overtook General Motors in 2008 to become world number one automaker, has seen its reputation tarnished by a litany of complaints ranging from unintended acceleration to brake failure and steering problems.
