INTRODUCTION
Our clients, Bulent and Anne
Ezal, planned lunch at a small restaurant near Big Sur.
As Bulent eased his Toyota Camry into a parking space near the
restaurant, the vehicle suddenly shot ahead, careened over a steep cliff
and smashed into the surf seventy-five feet below.
See Figure 1. Miraculously,
Bulent suffered few permanent physical injuries. However, his wife Anne died, a horrifying death.
As further discussed below,
Toyota of late has admitted that unintended accelerations can be caused by
"sticky gas pedals" and/or "all-weather floor mats"
that can jam the pedal. Here
however, as in many other reported runaway accelerations, the Ezal's
Toyota did not have all-weather floor mats, nor the specific gas pedals
identified in Toyota's Press Releases.
What then happened?
This article explores that
question, the history of runaway accelerations, pivotal issues essentially
disregarded by Toyota and other manufacturers, the likely reason for
runaway acceleration, and discovery techniques for getting at the root
cause of this deadly defect.
II.
THE HISTORY OF UNCONTROLLED ACCELERATIONS
A.
The 1980s - Audi 5000
In 1978, Volkswagen began
selling the first Audi 5000s in the United States.
Sales were strong, with sales of the Audi flagship doubling in its first
seven years in the U.S. market. These
initially popular vehicles, however, had a recurring problem:
Uncontrolled Acceleration.
From 1978 to 1987, consumers
reported over 1500 crashes involving sudden acceleration of Audi 5000s,
with 400 reported injuries and seven fatalities.
Many of the crashes were similar: The car was idling with the
automatic transmission in "park"; the driver shifted into
"drive" or "reverse"; and the car, suddenly and
without warning, wildly accelerated and could not be stopped before
hitting cars, trees, walls, or people.
One of those killed was
six-year-old Joshua Bradosky.
He died when an Audi 5000, driven by his mother, surged forward,
crashing him through a garage and pinning him to the garage wall.
Audi's response?
Essentially: The car is not defective; the drivers are.
Audi's public relations staff accused the drivers, emphasizing that
"maybe people are putting their foot on the wrong pedal."
The response by the National
Highway Traffic Safety Administration ("NHTSA"):
The car is not defective; the drivers are.
In 1989, NHTSA completed its investigation into "Sudden
Acceleration Incidents" ("SAI"), concluding "most SAI
probably involve the driver unintentionally pressing the accelerator when
braking was intended."
In short, despite the increased frequency of sudden accelerations
in certain model vehicles, and the driver (in virtually every incident)
reporting "foot on the brake" rather than accelerator, NHTSA
concluded it was all merely the result of the driver pressing the wrong
pedal.
Despite this ultimate
"finding" by NHTSA, as a result of prior work by trial
attorneys, journalists, safety advocates, and consumers, the Audi 5000 had
been recalled several times to correct problems that NHTSA itself
acknowledged could cause sudden acceleration.
In 1982, in a move
shockingly similar to today's Toyota headlines, NHTSA forced the recall of
the Audi 5000 because the driver's floor mats could cause sudden
acceleration.
Later, the placement of the brake pedal was blamed for some sudden
accelerations, and the Audi 5000 was recalled again for repairs.
In 1987, NHTSA identified defects that could cause "engine
surge" and demanded the recall of some Audi 5000s yet again.
Finally, that same year, the Audi 5000 was recalled to retrofit an
automatic shift lock to prevent "unexpected, sudden acceleration,
without prior warning."
Audi touted this final recall as the solution to most of the sudden
accelerations incidents.
With NHTSA's investigation
into "Sudden Acceleration Incidents" closed, and most unintended
accelerations attributed to driver error, NHTSA made no further recalls of
the Audi 5000. Long after the
recalls, however, consumers continued to report runaway accelerations with
the Audi 5000, even on vehicles with all recall repairs.
B.
The 1990s - Ford Motor Company
In the 1990s, consumers
began to report that automobiles with popular cruise control systems had
runaway accelerations. Ford
Motor Company absorbed much of the criticism, with numerous lawsuits filed
against it, and multiple NHTSA recalls related to sudden acceleration.
Unlike Audi's problem with
the Audi 5000, Ford's runaway acceleration problems crossed into many
models and various brands: Aerostars (NHTSA Recall ID No. 00V425000);
Contours (NHTSA Recall ID No. 99V194000); Escapes (NHTSA Recall ID No.
00V210001); Explorers (NHTSA Recall ID No. 03V280000); F-Series Trucks (NHTSA
Recall ID No. 99V062001); Focus Hatchbacks (NHTSA Recall ID No. 99V346000,
00V302000); Tauruses (NHTSA Recall ID No. 97V025000); Mercury Mystiques (NHTSA
Recall ID No. 99V194000); and Mercury Sables (NHTSA Recall ID No.
97V025000).
Most of these Ford recalls
involved the cruise control system. There
was particular focus on a design which allowed contaminants into the speed
control cable conduit or caused damage to the cable itself, resulting in
either a wide-open throttle or surging throttle.
The recalls, however,
ignored key consumer concerns regarding runaway accelerations. Prominent among them was whether transient electromagnetic
interference (EMI) could cause these unwanted accelerations. Some experts believed that transient EMI could cause the
electronic cruise control to signal the throttle to open, despite the
absence of accelerator input.
In addition, Ford was privy
to information indicating that EMI could cause vehicles to suddenly
accelerate out-of-control. Indeed,
in internal investigations on sudden acceleration, Ford concluded that
sudden unintended acceleration incidents increased with the introduction
of broadly applied electronics in 1984.
Ford also documented in internal memoranda that various
electromagnetic failures, including EMI, could cause sudden unintended
acceleration.
Ford apparently learned that
"the vehicle speed maintenance control system or >cruise
control system' . . . is capable in the event of >failure
or malfunction' of opening the throttle a substantial amount without
driver input." Indeed,
former Ford employees have admitted that unwanted electrical impulses
could open the throttle, causing sudden, unintended acceleration.
Ford generally denied
virtually all defect claims related to runaway accelerations, often citing
the 1989 NHTSA report of "drive pedal" error as evidence. Ford employees however apparently experienced incidents of
sudden unintended acceleration, with no reproduceable evidence of the
event. In one reported
incident, a Ford engineer, investigating a Ford Expedition for cruise
control problems, found that after pressing the "resume" button,
"the vehicle kept accelerating beyond the set speed and wouldn't
respond to brakes or the off switch."
Upon examining the truck, however, Ford could not find anything out
of the ordinary.
In another reported
incident, during a test drive of a Mercury Grand Marquis, a Ford employee
shifted into "drive", and the engine raced with the wheels
spinning, as if the accelerator was floored.
The employee stopped the car by braking as hard as he could.
The car later checked out normal.
In yet another reported
incident, a Ford employee crashed an experimental Aerostar prototype.
After shifting into gear, the vehicle accelerated to full throttle,
squealing the tires. The
employee removed his foot from all pedals, thinking he had accidentally
floored the accelerator, but the van continued to accelerate.
He shifted into "Park" but could not avoid crashing into
a wall.
Despite the above, Ford and
virtually the entire industry continued to rebuff opinions that EMI could
cause runaway accelerations, especially during related litigations.
C.
The 2000s- Toyota/Lexus
On August 28, 2009, with a
California Highway Patrol Officer at the wheel, a passenger in a new Lexus
ES 350 made a frantic call to 911.
Their vehicle was out-of-control, at 120 miles per hour, weaving
through traffic. The
passenger's final few words were "we're in trouble . . . there's no
brakes." The
driver, his wife, teenage daughter, and brother-in-law, the 911 caller,
were all killed as the vehicle slammed into another car and careened down
an embankment.
Since 2001, consumers have
lodged over 1,000 reports of sudden unintended acceleration in Lexus and
Toyota vehicles. Since
the 2002 model year, Toyota and Lexus sudden acceleration incidents have
resulted in 15 deaths.
In contrast, sudden unintended acceleration in all other vehicles
made by other manufacturers resulted in only 11 deaths.
Toyota first blamed these
unintended accelerations on the drivers, then admitted that its
all-weather floor mats could jam the accelerator pedal on certain models.
Hoping to rectify the floor-mat problem, in September 2009, Toyota
recalled millions of vehicles, including Camrys, Priuses, Avalons, Tacomas,
Tundras, and Lexus models.
The floor mat recall,
however, did not end the inquiry. NHTSA,
in an unprecedented rebuke, responded to Toyota's claim that no defects
existed in their vehicles with compatible and properly secured floor mats.
Indeed, NHTSA publicly stated that it recognized an
"underlying defect" in the design of the Toyota and Lexus
accelerator pedals, and the drivers' foot wells.
In January 2010, Toyota
announced yet another related recall.
This one recalled millions of more vehicles to correct
"sticking accelerator pedals".
Toyota's Press Release stated that its continuing investigation
found that certain accelerator pedals could mechanically stick in a
partially depressed position, or return slowing to the idle position.
Later in January, Toyota announced an unprecedented decision to
halt sales and production of eight (8) models of its vehicles, until it
could determine how to stop the gas pedals from sticking and causing
unintended accelerations.
The authors however believe
that Toyota's runaway acceleration problems will not end at "jamming
floor mats" or "sticky gas pedals".
A telling point is that complaints of unintended acceleration in
Toyota and Lexus vehicles increased dramatically after employment of
electronic throttles in the last decade. In
some models, sudden acceleration complaints increased five-fold after
introduction of electronic throttles.
III.
THE IGNORED ISSUE AND SOLUTIONS
A.
Introduction
Like the proverbial
"elephant in the room", the EMI issue must be directly addressed
by Toyota and the rest of the auto industry.
EMI is real. The
aerospace industry has been dealing with the ramifications of EMI/EMC
(electromagnetic interference/electromagnetic compatibility) since the
1960s. Said simply: The more
sophisticated electronics one stuffs into a small area, the more lethal
the EMI/EMC issue.
We have reached the 21st
Century, and with it comes reliance on an unprecedented number of
electronic gizmos in every new car. Some
more than others. Toyota as
the largest automobile manufacturer, and an undisputed leader in
electronic advances for automobiles is at the forefront.
As such, and with its current runaway acceleration woes, Toyota
will have to face the issue first.
B.
EMI/EMC
The electronic throttle
system that Toyota introduced at the turn of the century replaced the
mechanical link (usually a steel cable) between the driver's foot and the
engine's acceleration with a series of sensors, microprocessors, electric
motors and wiring. These
devices were located among a growing number of additional sensors,
processors, and wiring for a myriad of other electronic subsystems in a
relatively small space in the vehicle's engine area.
This, in and of itself, is a classic recipe for EMI/EMC problems.
As the aerospace industry
learned decades ago, manufacturers cannot simply continue to jam
electronic devices into small areas without testing and designing away EMI
dangers. If they do, spurious
signals that inadvertently and randomly excite near-by electronics are
inevitable. If those near-by
electronics include the engine control unit (or electronic throttle
system) runaway accelerations are to be anticipated.
EMI/EMC dangers can include
stray voltage, algorithm defects in the related software of the
microprocessor components, and random signals that excite other subsystems
(such as opening throttle control units).
Toyota, understandably,
wants a "quick fix" to its runaway acceleration problems. Sales, reputation and peoples' lives depend on it.
But limiting its investigations to mechanical things such as
"jamming floor mats" and "sticky gas pedals" is a
tragic mistake. Toyota (and
the industry as a whole) can no longer afford to disregard "the
elephant in the room": EMI/EMC.
The solution is not a
"quick fix". Eliminating
EMI/EMC dangers is a system design and test issue that affects every
electronic component and computer-driven subsystem in the vehicle. And the
more electronic components and microprocessors in a vehicle, the deeper
and darker the problem.
Besides testing for EMI/EMC
dangers at each step of the design process, safety analyses must be done.
In particular, Failure Modes and Effects Analyses (FMEA) must be
conducted to show that the system-design is free of EMI dangers.
Through careful design, test and on-going FMEA, electronic devices
can be safely integrated, insulated, and if need be isolated, and all
associated algorithms can be verified and validated to virtually eliminate
the risk of EMI. In over a quarter-of-century of product liability litigation,
however, the authors have yet to see an FMEA from any auto manufacturer
that comes remotely close to accomplishing and documenting the above.
So now is the time.
Toyota as industry leader, and saddled with its current
"runaway acceleration" problems should lead the way.
Future designs must thoroughly address EMI/EMC from the ground up.
Lives depend on it.
But what about the Toyota
vehicles already on the road? Retrofit
and perhaps redesign is necessary. If
Toyota has not already done so internally, it should immediately amass
what the aerospace industry calls a "tiger team" of
knowledgeable engineers across multiple disciplines (including auto
design, electronics, software and safety engineers) to beat back its
deadly problems. Suspect components and software should be modified.
Susceptible electronic devices, including wiring and sensitive
components, should be shielded, insulated and if necessary isolated or
retrofitted to eliminate EMI dangers.
C.
The Role of Product Liability Litigation
For well over 30 years,
product liability litigation has been at the forefront of auto safety:
Think Pinto "exploding gas tanks", interior padding,
airbag safety, roll-over propensity, etc.
It is especially effective where industry progress is thwarted by
profit concerns, and federal regulation is dwarfed by politics.
Runaway acceleration is no
exception. The authors, for
example, have been prosecuting related cases since the 1980s. We have learned that the best first steps are thorough
initial investigation and discovery.
In that regard, runaway acceleration cases should include, at the
outset, requests for documents (including electronic files), and
applicable interrogatories in the following fifteen (15) areas:
1.
All EMI/EMC testing and analyses related to the throttle control
system;
2.
All FMEA (as defined by Society of Automotive Engineers (SAE)
Surface Vehicle Recommended Practice J 1739) done related to the throttle
control system;
3.
All software definition documents related to the throttle control
system;
4.
The programming algorithms of the throttle control system;
5.
The design and manufacturing specifications and drawings (including
all configuration changes) for the throttle control system;
6.
All Technical Service Bulletins, as well as other information,
provided to dealers above the throttle control system and/or unintended
accelerations;
7.
The persons most knowledgeable at your corporation regarding
EMI/EMC, FMEA, testing, design, and design changes related to the throttle
control system and/or unintended accelerations;
8.
All customer complaints and inquiries related to the throttle
control system and/or unintended accelerations;
9.
All original warranty claims, extended warranty claims, and claims
for goodwill services paid by you related to the throttle control system
and/or unintended accelerations;
10. All lawsuits related to alleged
unintended accelerations and/or the throttle control system of
substantially similar vehicles;
11. All recalls or service campaigns
related to alleged unintended accelerations and/or the throttle control
system of substantially similar vehicles;
12. All documents necessary to
identify, access, read, verify and interpret the data in any device in the
subject vehicle which records, samples or processes pre-collision,
near-collision, collision and post-collision data (sometimes referred to
as "the black box");
13. All communications with any
government agency (including NHTSA) regarding unintended accelerations
and/or the throttle control system of substantially similar vehicles;
14. All internal investigations
regarding unintended accelerations and/or the throttle control system of
substantially similar vehicles;
15. All communications with your
dealers regarding unintended accelerations and/or the throttle control
system of substantially similar vehicles;
IV.
CONCLUSION
The history of runaway
accelerations; the fact that Toyota's mechanical "explanations"
are inconsistent with circumstances surrounding many if not most reports
of runaway accelerations; the reality of EMI/EMC dangers; and the
essential disregard of those dangers by manufacturers and government
overseers leave the public at risk, and consumers in jeopardy.
As with so many previous automotive defects, that safety void will
exist until manufacturers are spurred to find the real solution. And, as in the past, that void will be filled by product
liability litigation, and the type knowledge and techniques explored in
this article.
