Introduction
Section 207(c) of the Clean Air Act (Act) provides that
if a substantial number of any class of vehicles or engines,
although properly maintained and used, do not conform to the
emission standards when in actual use, the Administrator of
the Environmental Protection Agency (EPA) shall order the
manufacturer to submit a remedial plan to remedy the
nonconformi ty.
In many cases the Office of Enforcement, through its
Manufacturers Operations Division, is either directly or
indirectly responsible for the recall of nonconforming vehicles,
although the manufacturers often declare recalls without EPA
intervent ion. This report is a cumulative 1 is ting of all
recalls announced during the calendar year 1979.
The auto-related emission standards were established by
the Act to protect and enhance the quality of the Nation's
air so as to promote the public health and welfare. Hydrocarbon
(HC) and oxides of nitrogen (NOx) emissions contained in the
exhaust of motor vehicles form photochemical oxidants when
exposed to sunlight. Photochemical oxidants may cause
irritation to the respiratory system, eyes, and mucous
membranes. They are particularly hazardous to the health of
the elderly and very young. Carbon monoxide (CO), another
component of the vehicle exhaust emissions, combines with
hemoglobin in the blood stream reducing the amount of oxygen

distrjbuted throughout the body. Carbon monoxide is harmful
to persons who have heart ailments, lung disease, anemia, or
cardiovascular diseases.
Informal recall investigations are continually being
initiated by the Office of Enforcement. These often come to
EPA's attention through in-use testing programs, or citizen
reports. All reports of possible emission control system
failures are reviewed. If a widespread problem appears to
exist, a formal investigation is initiated. This investigation
may indicate that a substantial number of vehicles are not
complying with Federal standards. In this case, a recall
of these vehicles would be considered.
If a manufacturer determines that a specific emission-
related defect exists in twenty-five or more vehicles within
a model year, a defect report (DR) must be submitted to EPA
not mere than 15 working days after the defect'is found.
Defect reports give a description of the possible defect,
the number and type of vehicles estimated to have the
problem, the emissions impact of the defect, and any
indication of manufacturer follow-up. These reports are
available for review at the Public Information Center at the
Environmental Protection Agency, 401 M Street, S.W.,
Washington, D. C. 20460.

-------
-3-
Recalls are classified as either ordered (0), influenced
(I), or voluntary (V). If the results of a formal EPA
investigation indicate that a class of cars does not comply
with the provisions of the Clean Air Act, a recall is
ordered. When the manufacturer voluntarily recal1s the
defective cars after EPA has initiated an investigation, the
recall is considered influenced. Those recalls conducted
prior to an EPA investigation are considered voluntary.
After a recall is ordered, the manufacturer has 45 days
to submit a remedial plan to EPA for approval, or request a
hearing to contest the decision. The remedial plan describes
the proposed repair, the recall implementation procedures,
and the proposed owner and dealer notification letters.
After the remedial plan has been approved, the manufacturer
notifies the affected owners that the emissions nonconformi ty
in their vehicles will be repaired free of charge.
Table I of this report lists the number of foreign and
domestic recall campaigns announced in 1979. These include
ordered, influenced, and voluntary recal1s that have already
been initiated by the manufacturer as well as recalls in
which the remedial plan has not yet been approved by EPA.
The second section is a more comprehensive 1 isting of the
facts concerning each specific recall.

-------
-4-
EPA invites the public to report potential emission
control component failures. Persons with emission problems
or inquiries about other recalls should write to;
Director, Manufacturers Operations Division
U.S. Environmental Protection Agency
401 M Street, S. W. (EN-340)
Washington, D. C. 20460
Reports should indicate the make, model, year, engine
size and serial number (VIN) of the vehicle, if known, and
all pertinent facts relating to the suspected problem.
