Jeep Grand Cherokee SUVs that are not fixed may appear
to be in park. However, a hidden internal shaft lever within the transmission
can actually land on a flat space between reverse and park, leaving the
car in hydraulic neutral. From this spot, referred to as "false
park mode," slight vibrations or movements can allegedly cause the
Jeep's lever to slip into reverse gear and the Jeep to move.
For Jeeps produced from 1993 through 1998 that have not been repaired
under the recall, the shift from park to reverse could occur when the
Jeep's motor is running or shut off. A door slamming, or even an air
conditioner cycling, could cause the shifter to slip and move the vehicle
into reverse.
According to press reports, the rate of park to reverse complaints for
Jeep Grand Cherokees was more than five times greater than for any similar
SUV made by a different company. Prior to the recall, more than 860 people
complained to the government or to DaimlerChrysler about "inadvertent
rollway in reverse" incidents involving Jeep Grand Cherokees, which
were blamed for at least 359 crashes, 184 injuries and five deaths. |
