Occasionally, the vehicle will not lock when I use the fob or use the drivers manual locking switch on the door. This is happening when I exit the vehicle. I hit the fob lock button and the car beeps once, but the front drivers door does not lock, and the door lock does not move to a locking position, it stays in the unlocked position. When I hit the lock button on the fob, the car beeps 8 times and still does not lock. In order to lock the car, I have to enter the front passenger door and manually lock the front drivers door. The problem occurs about once per week. It started about a year ago.

February 25, 2014, I arrived for my 2 P.M. doctor's appt and drove very slowly into a parking space. I was constantly braking because the Toyota Avalon sport 2011 has lots of low trim in the front of the car and I did not want to scratch the car. I kept my foot on the brake, stopped the car, then opened the door to check the white line to see if I was in my parking space. Then, the motor began accelerating very rapidly. Before I could turn the engine off, the car lunged forward and I felt like I was airborne. Within seconds, the car hit the very tall heavy metal and glass doors of the doctor's office and stopped. The car was covered with glass. The metal doors of the office were damaged. Please note, the airbags did not deploy. The entire front of the car: Grill, headlights, fenders and hood were damaged. Thankfully no one was injured.

The passenger and rear door locks do not open with the remote key nor with the door-lock switch on the driver's door. The passengers could not enter the car. Their door had to be unlocked manually from inside the vehicle. This is a serious personal safety issue if you have an emergency and need quick entry for any reason...storm, fire, explosion, personal attack. The Toyota dealer could not find a cause.
