To whom it may be of some interest, june 19, 2008 i had a horrific experience with my sequoia. i own a 2007 sequoia and it only has 4200 miles on it. this past sunday i was starting from traffic when i gently stepped on the brake pedal to slow down in traffic when all of a sudden the seq. jumped from 0 to 60 or 70 mph. it took me off guard, i then pressed on the brake again trying to stop the vehicle or at least slow it down a bit but every time i took my foot off the brake the truck just wanted to take off totally out of control. it kept doing this for about a good minute. i thought for sure i was going to hit someone or something and injure my kids who were with me at the time. it was a frightening experience. i called for a service appt. at toyota of manhattan where i purchased the vehicle which was on said date and it happened again on the way to the dealership. i was 5mins from the dealership and they could smell the brakes. i explained the problem and they mechanics insisted it was the rugs of course i dispute it they said the rug probably got caught on the pedal. when i showed them how far the two were from eachother they then said it would get a diagnostic check. 4 hours later i was told it was the "brake booster". my problem was not the accelerator, but the brake itself. here i thought every time i stepped on the brake i thought the anti-locks were kicking in when in fact the brakes was trembling, a total malfunction...i waited several days for the part to ship from japan.. i would like warn other sequoia owners of the possibilities of this happening to them. thank you, above is the same letter i sent to toyota usa on june 2008. *tr
