Sudden Braking Incidents in Jeep Grand Cherokee SUVs under Investigation
The National Highway Traffic Safety Administration (NHTSA) has opened a Preliminary Evaluation investigation into certain model year 2014 Jeep Grand Cherokee vehicles.
An estimated 20,000 Jeep Grand Cherokee SUVs could be impacted by this investigation.
NHTSA's Office of Defects Investigation (ODI) has received nine complaints from owners of the Jeep Grand Cherokee vehicles in question alleging inappropriate activations of the autonomous braking system.
All nine complaints report unexpected braking incidents preceded by collision imminent brake warnings that resulted in a sudden reduction in speed while in traffic.
Two of the complaints reported autonomous braking incidents with no objects in the road that resulted in a rapid increase in brake force and anti-lock braking system (ABS) activations. The complainants allege experiencing multiple sudden braking events at different locations and road conditions.
ODI has opened this Preliminary Evaluation to assess the frequency, scope and potential safety-related consequences of the alleged defect.
The vehicle owner complaints referenced above can be reviewed online at SaferCar.gov under the following identification numbers: 10543837, 10713629, 10690650, 10663320, 10630362, 10596913, 10533622, 10533524, and 10651269.
