The hill assist does not work as should which causes the vehicle to drift backwards and engage the traction control/ brake system which hinders your ability from moving forwards. This is dangerous for many reasons such as drifting backwards into the vehicle behind you, if it’s icy it could cause the vehicle to break loose and go backwards uncontrollably, and cause unwanted delay in pulling out which has occurred multiple times. The local Lexus dealer said this has been occurring in these vehicles for a long time but indicated nothing is wrong. This is unacceptable because this has almost resulted in two accidents and the vehicle has 1500 miles on it.
Lock actuator is bad.
Air pump injection, air pump valve gone bad on my 2011 Lexus Gx460. Cost over $2000 to replace. This apparently seems to be a reoccurring issue in Toyota engines.
