Porsche Announces Voluntary Recall of 1999 & 2000 Porsche 911 Carrera 4 Models for Software Update
.
ATLANTA - Porsche Cars of North America 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.
