DEPARTMENT OF TRANSPORTATION
National Highway Traffic Safety Administration
[Docket No. 96-082; Notice 2]
General Motors Corporation; Grant of Application for Decision of
Inconsequential Noncompliance
This notice grants the application by General Motors Corporation
(GM) of Warren, Michigan, to be exempted from the notification and
remedy requirements of 49 U.S.C. 30118, and 30120 for a noncompliance
with 49 CFR 571.108, Federal Motor Vehicle Safety Standard (FMVSS) No.
108, ``Lamps, Reflective Devices and Associated Equipment.'' The basis
of the application is that the noncompliance is inconsequential as it
relates to motor vehicle safety.
Notice of receipt of the application was published on July 16,
1996, and an opportunity afforded for comment (61 FR 37109).
Standard No. 108 requires that turn signals be self-canceling by
steering wheel rotation and capable of cancellation by a manually
operated control. GM discovered that the self-canceling feature only
works intermittently after left turns on slightly less than 2,000 1996
Model Buick Skylarks, because of a ``defective multi-function switch.''
GM believes that the failure is inconsequential because it occurs
intermittently and in one direction only, and because the Skylarks are
equipped with a reminder chime that activates if the turn signal is
still on after \1/2\ mile of driving.
GM supported its application for inconsequential noncompliance with
the following:
``No more than 5.5 percent of the 1,969 vehicles, or 108 vehicles,
are predicted to have a defective switch. This prediction is based on a
sort of 400 switches, of which 22 were determined to possibly be
suspect. This projection may overstate the field condition since the
sort was very conservative; many of the suspect 22 switches may
function properly in vehicles. In addition, the projection is based on
a sort of the latest shipments of switches before the supplier
corrected its manufacturing problem. Since the condition was caused by
tooling dimensions drifting out of specification, the actual rate of
defective switches for the entire production run may well be less than
the projected rate.
``The self-cancel feature will operate properly for a majority of
turn signal activations even on vehicles with a defective switch. The
self-canceling feature works correctly when signaling for all right
turns, as well as for some left turns. The switch is sensitive to the
rate of turn signal lever actuation and position of the steering wheel,
and will not cancel only intermittently, for some left hand turns. On
one of the vehicles discovered with this condition, it took about 20
turn signal cycles to recreate the failure.
``All 1996 Skylarks have a turn signal reminder chime that will
signal the driver if the turn signal indicator is still on after \1/2\
mile of driving. Therefore, even in those instances when the self-
cancel feature fails, the driver will get an additional cue that the
turn signal is on and deactivate it.
``GM is not aware of any accidents, injuries, owner complaints or
field reports associated with this condition.''
No comments were received on the application.
NHTSA accepts GM's analyses of the reported noncompliance and
concur with their recommendation. The agency believes that the effects
of this referenced noncompliance will not affect motor vehicle safety
in a consequential position since the turn signal lamps meet all other
requirements of Standard No. 108. Furthermore, GM has stated that the
turn signals may be canceled through a manually-operated control and
the 1996 Skylarks have a turn signal reminder chime that will signal
the driver if the turn signal indicator is still on after \1/2\ mile of
driving. Although the agency is concerned by the ``defective multi-
function switch'' reported by GM on the 1996 Model Buick Skylarks, the
performance of the noncompliant equipment conforms to Standard No. 108
a substantial part of the time.
Accordingly, for the reasons expressed above, the petitioner has
met its burden of persuasion that the noncompliance herein described is
inconsequential to motor vehicle safety, and the agency grants GM'S
application for exemption from notification of the noncompliance as
required by 49 U.S.C. 30118 and from remedy as required by 49 U.S.C.
30120. (49 U.S.C. 30118, 30120; delegations of authority at 49 CFR 1.50
and 501.8).
Issued on: October 29, 1996.
