Tl* the contact owns a 2003 toyota sequoia. the contact stated that while driving 10 mph, he noticed that the vehicle was exhibitng an abnormal noise as if he were driving on a flat tire. after pulling over, he noticed that the front passenger tire was separated from the vehicle due to a broken lug nut. the vehicle was inspected by an independent mechanic and they advised him that he would need to install studs on the rotors and replace the lug nuts. the vehicle was repaired. the failure and current mileages was approximately 86,000. updated 05/25/11 *bf the consumer stated the wrong lug uts were installed on the vehicle. upated 06/03/11

While driving along at city street speeds, during dry weather, on paved roads, my vsc trac and trac off lights come on. no other warning lights come on. then a buzzer sounds for about 3 seconds. then at the same time, a strange grinding sound comes from underneath the car, and the brakes seem to start working for no reason. i quickly pull over, turn off the car. i check the outside of the car and see no indication of running over anything. i then start the car and all the lights are back to normal (off). this happens about 2-3 times a month, for about a month or 2 now. i have not been able to determine any problems. *tr

I have had my rotors and brake pads changed a few times due to a conspicuous issue with my vehicle. at braking times during any slight "hard" stop, coming from either highway or street speeds the vehicle starts to vibrate on the front end. tires seem to be wobbly and shake quite a bit. nearly had a few accidents due to this phenomena. have taken my vehicle in for servicing at reputable repair shops and have had rotors "cut" and new brake pads installed frequently. have even had to buy new tires, even though not needed, based on dealer recommendation. seems there is an issue with these toyota vehicles after having done some research and spoken to a few other sequoia owners. catastrophic brake failure is a possibility on these vehicles. will it take an injury or even a death to finally have someone delve into this issue?
