Air Brake Foot Control problems of the 2005 Toyota Highlander

My daughter leased a 2005 4 cylinder, fwd Toyota Highlander in February 2005, and has put on about 5,000 miles. The car was leased in louisville, ky. A few days ago she was driving on the highway at about 65mph, and noticed that the gas peddle was stuck, and would not come up so as to reduce the speed. The first time this happened, she managed to reach down and pull the peddle assembly up, and deceleration occurred. The next day this situation repeated 2 more times, the last time being on the way to the dealer to have the vehicle "repaired" under warranty. The dealer fixed the assembly, and stated the assembly had come loose. While the repair seems to have been successful to date, and the dealer was very cooperative, I thought you folks should know about this "defect" and be alert to the possibility of more such failures. While my daughter was too shy or reticent to contact you, I thought it's ineveryone's best interest to avoid possible future fatalities. Not everyone is as athletic or calm as my daughter in this type of situation. Thank you for your attention to this matter.
