My moonroof spontaneously exploded while accelerating from a stop. We were not hit by any object and were not traveling at a high rate of speed at the time. We heard a very loud "pop" followed by a rain of glass from the moon roof. Driver sustained cuts to his hand due from the glass shards.

I bought this 2023 GX460 new in October 2023 from Lexus of Towson in Towson, MD. It currently has approximately 3100 miles on it. Since owning it I have noticed that when coming to a stop and sitting still with the vehicle in gear and the brake pedal engaged normally that the vehicle will start to move on it's own causing more pressure needing to be applied to keep the vehicle still.

THIS VEHICLES PARKING BRAKE FAILS TO HOLD THE WEIGHT OF THE VEHICLE, UNLESS THE TRANSMISSION IS ENGAGED IN "P" (PARK). As a result, the weight of the vehicle rests on the transmission notch that is engaged with the Park position of the transmission. If the vehicle is stopped and the parking brake is engaged, the vehicle will roll in the direction of the downhill. The parking or emergency brake does NOT hold the weight of the vehicle without the transmission!
