The ignition key may be able to be removed from the ignition switch without the vehicle's transmission being shifted to the park position, which could allow the vehicle to roll unexpectedly as occupants exit the vehicle. This would increase risk of injury.
The tire placard on the body of the vehicle may list an improper tire size and tire inflation pressure for the vehicle on it. This could lead to the improper tire being mounted onto the vehicle, or improper inflation pressure used, which could lead to an accident.
The seat belt for the driver's seat may fail to restrain the driver properly in an accident. This would increase risk of injury.
The driver's frontal air bag may not inflate properly during deployment, resulting in possible increased risk of occupant injury.
