Small overlap front: driver-side

Rating applies to 2013-22 models built after January 2013

Tested vehicle: 2014 Jeep Grand Cherokee Laredo E 4-door 4wd

The Jeep Grand Cherokee was redesigned for the 2011 model year. Beginning with 2013 models built after January 2013, the seat belts and airbags were modified to improve occupant protection in small overlap frontal crashes. (Information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on the driver door or adjacent B-pillar.)

Driver restraints and dummy kinematics
The dummy’s movement was reasonably well controlled. The dummy’s head remained largely in contact with the frontal airbag, but its head still moved toward the intruding A-pillar because the seat belt allowed excessive forward excursion of the dummy's head and torso. The side curtain airbag deployed but does not have sufficient forward coverage to protect the head from contact with forward side structure and outside objects. The side torso airbag deployed.

Action shot taken during the driver-side small overlap frontal crash test.

The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was not maintained well.

During the crash, the seat belt allowed the dummy to move too far forward, as is evident from the gap between the seat back and the dummy's torso. The side curtain airbag did not extend far enough forward toward the A-pillar.

Intrusion of the parking brake pedal, door hinge pillar, and instrument panel contributed to a significant risk of injury to the left lower leg.

About the small overlap front test

Small overlap front: passenger-side

Rating applies to 2013-22 models built after January 2013

Tested vehicle: 2018 Jeep Grand Cherokee Sterling 4-door 4wd

The Jeep Grand Cherokee was redesigned for the 2011 model year. Beginning with 2013 models built after January 2013, the seat belts and airbags were modified to improve occupant protection in small overlap frontal crashes. (Information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on the driver door or adjacent B-pillar.)

Passenger restraints and dummy kinematics
The dummy’s head loaded the frontal airbag, which stayed in front of the dummy until rebound. However, the side curtain airbag did not deploy and the front passenger door opened during the crash, which shouldn't happen because the passenger could be partly or completely ejected from the vehicle. In fact during rebound, the dummy's head moved outside the vehicle, leaving the head vulnerable to contact with side structure and outside objects.

Driver restraints and dummy kinematics

Action shot taken during the passenger-side small overlap frontal crash test.

The dummy's position in relation to the door frame and dashboard after the crash test indicates that the passenger's survival space was not maintained well.

The side curtain airbag did not deploy, uncommon for 2018 model year and later vehicles, and the dummy's head bottomed out the frontal airbag and hit the dashboard hard.

The passenger door opened during the crash test, and the dummy's head moved outside the vehicle during rebound.

Intrusion of the dashboard and door hinge pillar contributed to a likely risk of injury to the right lower leg.

Moderate overlap front: original test

Rating applies to 2011-22 models

Tested vehicle: 2011 Jeep Grand Cherokee Laredo 4-door 4wd

The Jeep Grand Cherokee was redesigned for the 2011 model year. Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by Chrysler Corporation.
