general problems of the 2011 Toyota Avalon

I have had to replace my front brake rotors 4 times on my 2011 Avalon. . I currently have 173,800 miles with 75-80% of this mileage on the open highway. Several mechanics have indicated that this premature wear on the front rotors is highly unusual. My attempts to contact Toyota about this premature rotor wear issue have either no response or a form letter stating they have no issues with their brakes. My vehicle is serviced regularly and to me this is a very serious and potentially dangerous issue. Perhaps you can get the attention of Toyota to look into this matter.

While driving 5 mph from parking spot to front of restaurant to pick up passenger, car suddenly accelerated very fast without depressing gas pedal. Both feet were applied to brake pedal and car did not slow down or stop until it hit cement pillar causing extensive damage, totaling the car and causing injury to driver.

Sudden acceleration when shifted into reverse gear and the brakes would not even slow the car. It was only stopped by hitting a low retaining was, knocking it down, and then falling over the edge of the driveway and being suspended like a "see-saw" over the edge of the driveway with the possibility of a 10+ foot drop off into a wooded ravine.

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.

Had brake and steering problems. The steering wheel was really loose. I had to apply 95% of the brake before the brakes were engaged. I took it back to claremont Toyota in CA where I bought it. They just looked at it and said it's working like designed and sent me home. No other responses or assistance.

Foot firmly on brake, shifting to reverse. Engine roared to life and vehicle thrust backward. Followed by four other episodes of sudden acceleration while foot on brake. The last of these resulted in light rear-end collision. No visible damage to struck pickup. Front grill of Avalon visibly crushed. These five incidents occurred over a period of about nine days. I have refused to drive it since.
