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 gas pedal when the Seq. jumped from 0 to 60 or 70 mph .it took me off guard, i then pressed on the break 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.. Scared the chickens out of me. I thought for sure I was going to hit someone or something. I called for a service appt. which was today and it happened again on the way to the dealership. I was 5 minutes from the dealership and they could smell the brakes. I explained the problem and they first said it was probably b/c I had 2 car mats on the driver's side that possibly caused the truck to accelerate. 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 each other they then said it would get a diagnostic check. 4 hours later they told me it was the "BRAKE BOOSTER".
APPARENTLY MY PROBLEM WAS NOT THE ACCELERATOR, BUT THE BRAKE ITSELF. HERE I THOUGHT EVERY TIME I STEPPED ON THE BREAK i THOUGHT THE ANTI-LOCKS WERE KICKING IN WHEN IN FACT THE BRAKE WAS TREMBLING, A TOTAL MALFUNCTION... I am now waiting for the part to ship from Japan.....G R E A T..
Has anyone had a similar problem? If not, you now know what the cause is if you do experience the same.
