On 01/08/14, a female driver of a 2012 gl 450 was stationary, in the garage, with engine running. Before she exited the vehicle to check on her child in the rear of the vehicle, she pressed the park button on the drive select electronically-controlled column shifter. As she exited and walked around to her child, the transmission suddenly shifted into reverse, the vehicle travelled backwards and pinned her between the open driver's door and the garage wall.

January 2022 Crash

Car just reached 90k miles with limited driving. The airmatic suspension has been acting oddly for the past month - I would find it low in the rear in the morning after being parked in a flat garage. The next day the entire car would be lowered. Whe is turn off the car, you would hear air being released. Today, when parked, there was a loud explosion, the car shook for a few minutes and then the entire thing sank to the wheel wells.

Reported at 90,000 miles, July 2018

The rear suspension became soft after the dealer did an intial check after I complained about the vehicle feeling unstable after speeds of 70MPH. I had both air shocks changed in the rear. After two (2) months the front suspension on the passenger also started to leak causing the vehicle to suspension to automatically adjust in the front while driving or parked. This occured whether the vehicle was parked or in motion, highway or city streets.
