U.S. News and World Report Offers Five Reasons to Buy a Toyota

It's hard to think of another company that nose-dived as fast as Toyota has. A few months ago, millions of drivers considered Toyota the gold standard for automobiles, with quality and reliability you could practically take for granted. Then came mysterious gas-pedal problems, claims of deadly "sudden acceleration" incidents, the global recall of more than 8 million vehicles, and vacillating assurances from shellshocked executives. The recalls could end up costing $2 billion or more. Toyota's sales have plunged, and its U.S. market share has fallen from 17 percent to 13 percent in just two months. The collapse rivals Enron or Lehman Brothers.

What's different about Toyota, though, is that it will recover. The automaker has deep pockets and tons of talent. Diffident CEO Akio Toyoda may not be the right man to lead Toyota through the worst crisis in its history, but sooner or later the company will regain control and get back on the pavement. It may even end up a better company than before. Meanwhile, Toyota automobiles could be a smart buy, with dealers forced to offer discounts and other incentives to move merchandise sullied by the scandal. Shoppers should research prices at sites like Edmunds.com or kbb.com to make sure that the price paid today is commensurate with the likely resale value down the road. If the price seems right, there are several other good reasons to buy a Toyota:

Safety concerns are exaggerated. The problems are serious, but political posturing in Washington and media hype have created the impression that every Toyota is dangerous. That's ridiculous. The sudden-acceleration incidents at the center of the controversy have been "linked" to 52 deaths over the past decade or so. Toyota has sold more than 20 million vehicles in the United States during that time. By those numbers, rough math suggests the odds of a sudden-acceleration fatality in a Toyota vehicle are on the order of 1 in 400,000—not exactly a death wish for somebody buying a Toyota. And those odds could end up much lower. Deaths now considered linked to sudden acceleration could later be proved to have been caused by something else—including drivers who were pressing the gas pedal instead of the brake. No driver wants to admit doing that, but the fact is, it happens.

None of that is meant to disparage people who have been killed or hurt in a Toyota, and recent revelations depict a company that seemed unsympathetic to genuine complaints from customers. But the acceleration problem could turn out to be far less widespread than current hysteria suggests. It's worth recalling that the Audi sudden-acceleration incidents in the 1980s—at first thought to be related to vehicle flaws—were later proved to be entirely the fault of drivers. Meanwhile, by virtue of its woes, Toyota is probably paying more attention to safety right now than any other automaker, to include the extraordinary step of shutting down factories to retool the gas-pedal assembly in many popular models. Toyotas coming off the assembly line these days are probably subject to more quality control than most other cars on the market.

Recalls aren't the whole story. Being forced to recall millions of vehicles is a big deal, but Toyota still seems to perform better than other automakers when it comes to the kinds of complaints that lead to recalls. Data analyzed by Edmunds.com, for example, show that there have been many more complaints lodged against Toyota for sudden acceleration since 2005 than for any other automaker. But overall, Toyota has drawn far fewer complaints than most competitors, which is consistent with its once sterling reputation. Edmunds found that over the past 10 years, Toyota accounted for just 9.1 percent of all complaints filed with the government, even though it racked up 13.5 percent of all car sales. So despite the acceleration issue, Toyota still performs better than most in terms of complaints.

Toyota's not alone. Internal documents showing that Toyota boasted of saving $100 million by avoiding a series of recalls make the Japanese automaker seem singularly sinister. But all automakers try to avoid recalls. Toyota just happens to be the one that got caught boasting about it, since it's the company under investigation right now—and subject to subpoena. And all carmakers know that the Obama administration is "not industry friendly," as another embarrassing Toyota document put it. Obama, like Bush, is requiring steep improvement in fuel economy, which will force all automakers to invest heavily in new engine technologies. That arguably hurts the Detroit automakers most, since their fleets get the worst gas mileage and they have the farthest to go. And anybody who still has doubts should ask Rick Wagoner or Fritz Henderson if the Obama administration is industry friendly; they were both forced to resign as CEO of General Motors, in the midst of the company's bankruptcy and federal bailout.

The cars are still good. Of 18 Toyota vehicles, seven rank in the top three in their category in the U.S. News Best Car and Truck rankings, including the Avalon sedan, Sienna minivan, Sequoia SUV, and Venza crossover. Five of 12 Lexus vehicles rank in the top three. In itslatest quality ratings, J. D. Power & Associates ranks Lexus first and Toyota seventh, out of 37 automotive brands. Consumer Reports named the Toyota Prius one of its 10 "Best Picks"for 2010, despite a recall involving brakes. And CR is poised to restore its coveted "recommended" status to eight vehicles it suspended from its ranking in the midst of the mushrooming recall controversy: the Avalon, Camry, Corolla, Highlander, Matrix, RAV4, Sequoia, and Tundra. Toyota's overall quality has slipped from the stratospheric highs of a few years ago, but there are still few automakers that can match its record across their entire fleet.

White-glove treatment. To win back customers and alleviate safety concerns, Toyota will pick up and return some recalled cars, so worried owners don't have to drive to the dealership. Toyota is also offering rental cars or rides to work to some owners getting their cars fixed. And CEO Toyoda has said that the company must start paying more attention to customers. Toyota certainly has room to rise: It ranks 17th out of 23 on J. D. Power's customer-service index. If Toyota is serious about rebuilding its business, it has to start by wooing skeptical consumers. That's a boon for buyers.

Comprehensive Analysis Raises Concerns About Gilbert Congressional Testimony, ABC News Segment


2010 Toyota Electronic Throttle Control 004
Sequence and Nature of Artificially Manipulated Faults Unrealistic,
Televised "Unintended Acceleration" Staged With Virtual Remote Throttle Control
TORRANCE, Calif., March 8, 2010 -- Today, during a live webcast, Toyota raised serious concerns about the validity, methodology and credibility of a demonstration of alleged “unintended acceleration” in a Toyota Avalon by Professor David Gilbert of Southern Illinois University and depicted in ABC News broadcasts and on-line segments.
A comprehensive analysis conducted by a world renowned engineering group, as well as testing by Toyota, has concluded the following about Professor Gilbert’s demonstration:
• The vehicle’s electronics were rewired and reengineered in multiple ways, in a specific sequence, and under conditions that are virtually impossible to occur in real-world conditions without visible evidence
• Toyota vehicle electronic systems were actively manipulated to mimic a valid full-throttle condition
• Substantially similar results were successfully created in vehicles made by other manufacturers.
In the demonstration dramatized by ABC on February 22, Professor Gilbert, assisted by segment reporter Brian Ross, asserted that he had detected a “dangerous” flaw in the Toyota electronic control system that he alleged could lead to unintended acceleration.
The following day, Professor Gilbert offered a preliminary report of his findings in testimony to the U.S. House of Representatives Energy and Commerce Subcommittee on Oversight and Investigations.
Engineers at Exponent, one of the country's leading engineering and scientific consulting firms, as well as Toyota engineers, have reviewed and recreated Gilbert’s demonstration with substantially similar results in representative vehicles of other makes.
Separately, at Toyota’s request, Dr. J. Christian Gerdes, associate professor of mechanical engineering at Stanford University and the director of the Center for Automotive Research at Stanford (CARS), conducted an independent review of Professor Gilbert’s testimony and the preliminary report presented to Congress.
Their findings were demonstrated today at a news conference during which the accelerator circuitry of a Toyota Avalon, as well as a sampling of well-regarded and popular competitive makes, was rewired and manipulated as Gilbert did in his demonstration.
Kristen Tabar, general manager of electronics systems, Toyota Technical Center, summarizes three of the major concerns with the artificial nature of Professor Gilbert’s demonstration.
“First, an electrical circuit that has been reengineered and rewired will not behave as it was originally designed and engineered,” said Tabar.
“Second, no automaker can or should be expected to design detection strategies for artificially created events in the absence of any evidence that such an event can occur in the real world.
“Third, if the artificial condition created by Professor Gilbert had occurred in the real world, it would have left readily detectable fingerprints.”
Exponent and Toyota engineers have found no evidence to suggest that any of the steps of Professor Gilbert’s demonstration exists in the real world. Thus, the fact that the Toyota Avalon used by Professor Gilbert did not show a Diagnostic Trouble Code after his demonstration does not indicate an undetectable safety defect. The same is true of the representative vehicles of other manufacturers tested by Exponent and Toyota.
Professor Gilbert’s reengineering and rewiring of the vehicle’s electrical system involves the following manipulations in a specific sequence. First, the protective insulation on two separate wires that carry the accelerator pedal position signals to the Engine Control Module must be individually cut or breached. Next, these wires are connected to each other through a 200 Ohm resistor.
This contrivance, by itself, did not cause an increase in engine speed. To cause an increase in engine speed, it is necessary to cut the insulation on a third wire, the 5-volt power supply to the accelerator pedal, and force a low resistance connection between the power supply and the secondary signal wire.
The resulting increase in engine speed is a result of the subsequent artificial and sudden application of the 5-volt power supply to this signal line with the rewired circuit. When subjected to similar unrealistic reengineering and rewiring, the competitive vehicles evaluated by Exponent and Toyota achieved substantially similar results with varying levels of resistances.
This manipulation of electrical components and a power source created artificial voltages that the engine control module, or ECM, would interpret as valid accelerator pedal signals. In essence, this test created a virtual, remote control accelerator pedal that replicated the vehicle’s own normally functioning accelerator pedal.
Also contrary to statements made in the ABC News story, had short circuits of the kind artificially created by Professor Gilbert occurred in real-world driving conditions, they would have left visible evidence such as damage or deterioration of the wiring and components.
As revealed in their testimony before Congress, Professor Gilbert’s Preliminary Report was commissioned by Sean Kane, a paid advocate for trial lawyers involved in litigation against Toyota and other automakers. Mr. Kane also appeared on the ABC News broadcast in support of the claim that Professor Gilbert’s demonstration revealed a flaw in the electronic throttle control system that could lead to “runaway” Toyota and Lexus vehicles. The relationship between Mr. Kane, Professor Gilbert and the trial lawyers who support Mr. Kane’s advocacy was not revealed by ABC News during the newscast, nor was Toyota offered an opportunity to view the demonstration or given time to respond.
Toyota believes that the public and Congressional committees have been misled by Professor Gilbert’s demonstration and the dramatization of it by ABC News. This has cast unwarranted doubt on the safety of Toyota and Lexus vehicles. Toyota remains confident in the integrity of the electronic throttle control system in its vehicles and there has been no reliable evidence of any kind to the contrary presented to the media or to Congress. Toyota’s electronic systems have multiple fail-safe mechanisms to shut off or reduce engine power in the event of a system failure. Extensive testing of this system by Toyota has not found any sign of a malfunction that could lead to unintended acceleration.
Toyota has commissioned Exponent to conduct a comprehensive analysis of the electronic throttle control systems in Toyota and Lexus vehicles. No limitations of any kind were imposed on Exponent by Toyota. This evaluation is ongoing. An interim report of Exponent’s findings has been provided to Congress and establishes the functionality of the electronic throttle control fail-safe systems. The final results of Exponent’s exhaustive analysis will be made public when completed. As with all such reliable engineering analyses, Exponent’s final results will provide the data and information necessary for others to validate Exponent’s conclusions.
