Voluntary Recall of 1999 & 2000 Porsche 911 Carrera 4 Models

17 April 2000

Porsche Announces Voluntary Recall of 1999 & 2000 Porsche 911 Carrera 4 Models for Software Update
    ATLANTA, April 14 Porsche Cars of North America today
announced a voluntary recall of 1999 and 2000 Porsche 911 Carrera 4 models to
update the software in the instrument cluster that determines fuel quantity.
The recall involves a total of 2,734 vehicles in the U.S. and 177 vehicles in
Canada.
    The layout and particular shape of the Carrera 4 fuel tank does not allow
direct measurement of the fuel level over the entire measuring range, but
rather demands special measures for calculating the level in the bottom third
of the tank.  If unfavorable electrical tolerances coincide in the electronic
logic unit, it is possible that the fuel level and range of remaining fuel (in
vehicles with on-board computer) may be displayed incorrectly.
    This means that the display indicates a higher fuel level to the driver
than is actually available and therefore, in some circumstances, the vehicle
may run out of fuel causing a loss of power and thus the potential for an
accident.
    The control unit, which determines the fuel level, will be reprogrammed to
more accurately estimate the remaining fuel.  Porsche has already notified
dealers of the recall and provided the updated software to them.  Owners will
be notified via First Class mail the week of April 10, 2000.
    Porsche discovered the problem during analysis of field reports and
product observations.  It is unaware of any accident or injuries resulting
from this problem.
