As well, the transmission may be shifted out of PARK without first depressing the brake pedal. The key may also be rotated to the OFF position and removed while the shifter is not in PARK. These issues could result in unintended vehicle movement, which could cause a crash resulting in property damage and/or personal injury. Correction: Dealers will inspect and, if necessary, replace the steering column assembly.
