Ford Offers “False” Testimony; Alliance Swears to It

Posted on | by admin

From the annals of chutzpah: On March 12, the Alliance of Automobile Manufacturers filed a friend of the court brief to head off a potentially disastrous breach in the auto industry’s carefully constructed dam around the causes of unintended acceleration (UA). To wit, there are no electronic causes of unintended acceleration. This phenomenon, as the industry and the National Highway Traffic Safety Administration would have it, is solely caused by drivers hitting the wrong pedal and mechanical causes, such as pedal entrapment and bound Bowden cables. Electronic systems cannot have electronic malfunctions that can go undetected or cause UA, got that?

William T. Swigert, the Senior Judge of the Florida’s Fifth Judicial Circuit, however, had no respect for industry/government mythology. He set aside a jury verdict in favor of Ford Motor Company, after deciding that Ford’s victory in Stimpson v. Ford was won with “false and misleading” testimony and defrauded the federal government to boot, by claiming that it knew of no other cause of unintended acceleration than driver error and concealing years of testing that showed that electromagnetic interference was a frequent root cause of UA in Ford vehicles.

NHTSA Proposes Rubber Stamp Brake Throttle Override Rule

Posted on | by admin

For the second time in 40 years, the National Highway Traffic Safety Administration is attempting to upgrade the accelerator control standard by proposing that manufacturers be required to equip all vehicles with a brake override.  A brake override system cuts throttle voltage in electronic throttle control (ETC) vehicles when the brakes and throttle are in conflict. Variations of this type of fail-safe have been incorporated in a number of ETC equipped vehicles since the 1990s.

“We considered establishing a design requirement as the sole requirement for BTO, but the differences among BTO systems currently available from different vehicle manufacturers are significant enough that a design requirement by itself cannot effectively accommodate them all without being overly complex and/or design restrictive. By combining a relatively simple performance test with the basic equipment requirement described above, we can achieve a robust standard which is largely performance-based and minimally costly or burdensome.”

The Notice of Proposed Rulemaking is in direct reaction to the Toyota Unintended Acceleration (UA) crisis, noting the August 2009 deaths of California Highway Patrol Officer Mark Saylor, his wife, daughter and brother-in-law in Lexus ES350 loaner that experienced a UA event at highway speed. But, the proposal appears to be more of a political response than a technological one. It ignores past recalls for UA events that are electronically caused; and it fails to base this upgrade on any statistical analysis. It merely codifies manufacturers’ current equipment without teasing out the differences between more effective and less effective brake override systems, such as the Toyota system, which doesn’t activate in some of the most frequently reported UA scenarios – when the driver’s foot is on the brake – or on no pedal. According to Toyota’s “Smart Stop Technology,” “the feature doesn’t engage if the brake pedal is depressed before the accelerator pedal. The driver must press the accelerator first and then depress the brake.”

Antony Anderson, a U.K.-based electrical engineering consultant who has studied unintended acceleration, says that the rule fundamentally misses the essential ingredient in any failsafe system – independence from the malfunctioning component. This is why many machines, from motorcycles to escalators, have separate kill switches that can independently remove power from the throttle, he says.

“For some reason, the automobile industry seems to think they don’t need to bother,” Anderson says. [The agency] “has a well-developed NHTSA-speak, where they are all the time trying to minimize the possibility of an electronic malfunction.”

“This just captures the state of the industry, not the state of the art,” says Neil Hanneman, an automotive engineer who have overseen automotive electronic designs and has consulted with Congress on Toyota unintended acceleration. “For it to really be a robust standard it would have to address things that have not been addressed yet – which will be with the electronics.” Continue reading →

The Poker Face of Wall Street Calls NHTSA’s Bluff

Posted on | by admin

We read uber-Risk Manager and author of The Poker Face of Wall Street, Aaron Brown’s post “Sympathy for the Flash Crash” in Minyanville, a business and investment information website, with great enthusiasm. It was fascinating to see a business pundit draw parallels between Toyota Unintended Acceleration and the flash crash of May 6, 2010, in which the Dow dropped about 1,000 points, but recovered almost immediately afterward. It was refreshing to read a financial columnist who actually understands what happened after NHTSA tried to wrest control over an elusive technical problem. He writes:

“…the net result was that the agency ordered the recall of 8 million vehicles and levied the maximum allowed civil fine, then waited for the problem to go away on its own before issuing a study denying there had been a problem in the first place because they looked really hard and couldn’t find one.

When you don’t understand a system, throwing experts at it to announce they can’t understand what happened so it must have been human error, is an unconvincing—but irresistible—tactic.”

While we part company with Mr. Brown over the possibility and advisability of implementing regulation to fix the problem, and a few other details, his viewpoint is worth a read. The good folks at Minyanville kindly gave us permission to re-print it.  (The original article can found here on Minyanville.)


Sympathy for the Flash Crash

The entire modern world has become too complex for anyone to understand, and therefore, too complex for anyone to fix with top-down rulemaking.

MINYANVILLE ORIGINAL When I learned to drive 40 years ago, there were direct mechanical linkages between the car’s controls and its wheels and power train. When I turned the steering wheel, my muscle power (mediated by some levers and gears) changed the direction of the wheels. Accelerator, brakes, heater dial — all affected things through direct physical actions. We make fun of someone who confuses effects with causes by saying he tries to slow down a car by moving the speedometer needle. But in that 1962 model VW bus, pushing down the speedometer needle would, in fact, increase friction on one rear wheel and reduce the speed of the car. The cable was too delicate to provide significant deceleration, but in physical principle it would work.

Technical Upstart Schools NHTSA on Toyota Electronics

Posted on | by admin

Why can’t consumers get with the program?

Toyota – even with its technical difficulties, bad press and a tsunami that devastated Japan last year – is still a very wealthy corporation with a multi-billion-dollar bottom line. We shudder to contemplate how many millions the automaker spent on public relations, intimidation campaigns, advertisements, image consultants, outside counsel and scientists for hire. The money was laid on thickly enough to keep things cozy on almost all fronts.

And yet….it cannot stop the maddening trickle of unintended acceleration crashes into supermarkets, restaurants and other benighted retail establishments. And it cannot stop the drip, drip, drip of questions from consumers. We are still reading Toyota UA complaints with great interest, and recently we came upon a complaint from a 2004 Tacoma owner from Hopkinton, New Hampshire who witnessed a UA event in his driveway – much like two Office of Defects Investigation engineers did about a year ago in the presence of Prius owner Joseph McClelland (see Government Officials Video Electronic Unintended Acceleration in Toyota: NHTSA Hides Information, SRS Sues Agency for Records)

Like Mr. McClelland, an electrical engineer who happened to be the director of the Federal Energy Regulatory Commission’s Office of Electric Reliability, this gentleman is not a typical consumer. He is, by his own description, an engineer who wrote a book on troubleshooting servo systems. Like Southern Illinois University Automotive Electronics Professor David Gilbert, another curious Toyota owner with the technical skills to run some tests, he has noted the lack of fail safes and redundancies and the high risk to safety.

Here is his April 18 report to NHTSA: Continue reading →

NHTSA’s FOIA Problem

Posted on | by admin

Safety Research & Strategies, a Massachusetts safety research firm that advocates for consumers on safety matters, has filed its third Freedom of Information Act lawsuit against the U.S. Department of Transportation alleging that the National Highway Traffic Safety Administration (NHTSA) has improperly withheld documents – this time related to in the Evenflo infant seat recall of 2008.

“NHTSA is the DOT’s only designated public health agency,” says Sean Kane, president of SRS, “Decision-making on important safety matters should not be a private affair between the agency and the regulated.  We will continue to press for the release of documents that should be in the public domain.”

Evenflo recalled the Discovery infant carriers in February 2008 – one year after Consumer Reports, a Consumer Union (CU) publication, printed a controversial story rating rear-facing infant car seats in front and side-impact sled tests. The CU tests showed that only two of the 12 seats performed well in tests and most failed.  And as part of the story, CU urged the recall of the Evenflo Discovery.

NHTSA conducted its own sled tests to check CU’s results and found that the organization’s testing contractor, Calspan, had assessed the seats under conditions that represented a more-than 70-mph impact, instead of the 38.5 mph intended. CU profusely apologized and withdrew its report.

One year later, NHTSA and Evenflo simultaneously released brief announcements that the juvenile products company would recall 1.1 million Discovery infant seats. Using strikingly similar language, both press releases referenced recent tests conducted by NHTSA and Evenflo which showed that “this car seat has the potential to separate from its base.” Continue reading →

Another Toyota SUA Fatality?

Posted on | by admin

The Whittier Daily News reported yesterday on the death of 26-year-old Rosie Manzanares, a bicyclist who was struck and killed yesterday by a Toyota driver backing out of a parking space.

According to the California Highway Patrol of Santa Fe Springs, Angelica Cuevas, 78, was backing her 2012 Camry from a parking spot as Manzanares rode by:

“Halfway out of the parking stall, Mrs. Cuevas stopped her vehicle. As Ms. Manzanares was riding directly behind Mrs. Cuevas’ vehicle, Mrs. Cuevas rapidly accelerated her vehicle for unknown reasons.”

Given Cuevas’ age, we know that NHTSA and Toyota would chuck her case into the driver error file without a backward glance. We’re not so sure. We don’t know all the facts in the Manzanares incident, but it appears to have the key ingredients of a Toyota Unintended Acceleration parking lot incident.

These scenarios were not the subject of NHTSA’s most exhaustive research effort ever undertaken anywhere, by anyone, about anything. But, they are common. Even though the NHTSA-NASA Super Team didn’t bother to study surges at low speed, the agency noted their frequency in Technical Assessment of Toyota Electronic Throttle Control (ETC) Systems:

“Further review of the stationary and low speed incidents (combined) found that parking lot entry and exit accounted for the largest share of these incidents (40% of VOQs 64% of crashes. Many of the parking maneuver narratives reported incidents characterized by high engine power either after the driver applied the brake or immediately after shifting the transmission.”

In the case of older Toyotas with Potentiometer-type pedals one of the known electronic reasons was shorts caused by tin whiskers. The NASA scientists running tests on defective Camry pedals found that there is one scenario in which a resistive short in the Accelerator Pedal Position Sensor could lead to a surge without setting a diagnostic trouble code: Continue reading →

Burning Question: Why are Some Manufacturers Investigated for Door Fires, Others Not?

Posted on | by admin

Karen Swicker’s used 2002 Subaru Outback was new to her – less than a year old, when the driver’s side door ignited as she drove look along a Newburyport, Massachusetts road on February 16. The first puff of smoke sent her to the side of the road. As she came to a stop, the wisps had turned to a cloud. When the Fire Department pulled the door off, it burst into flames, and fire fighters had to cut the electrical wires from the harness.

This might have made a memorable entry in Subaru’s new marketing campaign, First Car Story, in which a driver can used an automated computer program with music and graphics to wax poetic about the elderly El Dorado with the duct-taped bumper that ferried him and his friends to the malt shop.

As Alan Bethke, Subaru of America’s director of marketing communications said in a statement: “The First Car Story campaign provides a creative outlet for reliving those unique, funny, unforgettable car experiences anyone who had a first car can relate to.” Continue reading →

Another CO Smart Key Death… and what Happens when Smart Keys Collide?

Posted on | by admin

Tell us again why electronic keys are an automotive technology advance?  Apparently, they’re so great that our National Highway Traffic Safety Administration has to re-write the Federal Motor Vehicle Safety Standard 114 (in a ham-handed way) to accommodate them.  And so super-duper that these new electronic ignition system vehicles are introducing new hazards that are killing and injuring consumers.

The Palm Beach County Sheriff’s office is investigating last week’s carbon monoxide poisoning deaths of Adele Ridless and Mort Victor. The couple is suspected to have succumbed to a build-up of carbon monoxide emanating from their Mercedes with a keyless ignition, parked in an attached garage. The sheriff’s office declined comment pending the outcome of their investigation.

Toyota – whose clever keyless ignition system has been implicated in at least two other carbon monoxide deaths – last month issued a Technical Service Bulletin noting that two “Smart Keys” from different vehicles in close proximity can knock the system for a loop. The February 24 notice covers some 2011 and 2012 Lexus models:

“Some 2011 and 2012 Lexus models may exhibit a condition where the Smart Key system is inoperative when another vehicle’s Smart key is in or near the vehicle. The following functions may also be affected: wireless remote operation, Smart access, and Smart start. The combination meter multi-information display may show the message: “Key not detected” when attempting to start vehicle and when driving.”

What are they talking about? NHTSA and the automakers have told us that the key in an electronic system is an invisible code inside the vehicle’s ignition module. So does that mean if you park next to another Toyota or some other manufacturer with an electronic ignition, your shiny new Lexus won’t start? Wow, that’s going to make parking in public lots a whole lot tougher. Continue reading →

Toyota Throws a Hissy

Posted on | by admin

Last week CNN’s Anderson Cooper 360 aired a six-minute-plus story about a 2006 confidential Toyota document showing that a pre-production vehicle in Japan experienced an unintended acceleration. The vehicle was an overseas model, identified as the 250L, equipped with adaptive cruise control. Its U.S. counterpart did not use that system, but the internal report did note that a “fail-safe overhaul” would be needed for another production vehicle that was sold in the U.S. — the Toyota Tundra.

Toyota tried to fight off the story with the survival instinct of a 1,000-lb. blue marlin at the end of a reel and tackle. Its central argument was that the document had been mistranslated and the condition noted in the pre-production test had nothing to do with unintended acceleration. The automaker trotted out English language speaker and Toyota entertainment systems engineer Kristin Tabar to rebut the translation’s literal and substantive meaning. CNN paid a Japanese translation house with experience in automotive technical documents to take a crack at it, and its version was pretty similar to the first English translation. (You can watch the story here.)

There were a series of legal parleys, but when the dust settled, Toyota lost, the story aired and the public relations team was left with nothing but its poison pen. In high dudgeon, Toyota complained about CNN’s unmitigated temerity to suggest the Toyota has been less than truthful in discussing all of the possible causes of unintended acceleration in its vehicles.

The Heavy Price of a Delayed Recall

Posted on | by admin

Goodyear has notified the National Highway Traffic Safety Administration that it is recalling 40,915 Wrangler Silent Armor flagship tires, more than a year after the company observed a higher rate of warranty and property damage claims, and three months after two Texas college students died in a tire failure that precipitated a rollover crash.

The August 1, 2011 incident claimed the lives of Matthew Smith and his passenger Kerrybeth Hall, as Smith drove southbound on U.S. Highway 67 in Pecos County, Texas. The left rear Wrangler Silent Armor tire on the 2008 Ford F-150 pickup de-treaded, causing the pick-up to skid and rollover. Smith was fatally ejected from the F-150. Hall, who was properly restrained, also suffered fatal injuries in the crash.

“I think Goodyear was getting lot of warranty claims, but said, ‘Let’s see what happens,” says David T. Bright, an attorney with Sico, White, Hoeschler & Braugh of Corpus Christi, TX, who represents Gerry Lynn Wilkinson, Kerrybeth’s mother, in the civil case against Goodyear. “Then Goodyear waited another 12 months, and decided:  Hang on. Let’s wait a while longer. And three months later, these two people got killed.”

According to documentation Goodyear filed with the National Highway Traffic Safety Administration (NHTSA) on February 22, the tiremaker had first noticed elevated property damage and warranty claims for the Wrangler Silent Armor tire, during its May 2010 review of Early Warning Data. Over the next 12 months, the company would continue to see high levels of warranty and property damage claims specifically for six sizes of the tires produced at its Fayetteville plant. But Goodyear still resisted a recall, passing off the uptick as isolated cases caused by “stone drilling damage and other external damage to the tires.” Continue reading →
