Open the full vehicle complaint log (all categories)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 initially caught me off guard several times. It is a repeatable problem. I can see that the engine RPM's are increasing by 100-300 by without throttle input which seems to trigger the need to apply more brake. I searched on forums and found other toyota/lexus, including GX owners complaining about this. This is dangerous for obvious reasons.
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!
