Traction Control Light On problems of the 2004 Toyota Sequoia

The contact owns a 2004 Toyota Sequoia. The contact stated that the traction light remained illuminated and the brake pedal traveled to the floorboard. The traction control, brake, and check engine lights illuminated. The vehicle was taken to a local dealer where it was diagnosed that the software for the brake control module needed to be updated. The manufacturer was made aware of the failure and gave the contact a reference. The vehicle was not repaired. The failure mileage was 120,000.

On four seperate occasions during low speed left turns my 2004 Toyota Sequoia has shuttered and struggled to stay on the road, traction control light comes on and beeps, and brake light eluminates. Vehicle also shutters when braking at low speeds. I took it to a Toyota dealership for service and was told the master cylinder needed to be replace. I took the vehicle to a certified mechanic to relace master cylinder, because of Toyota's high price to replace. The mechanic could not find any issue with the master cylinder and suggested it was an issue call a "low speed drop" and was probably related to the abs sytem or trac control. Called dealership and asked what type of diagnostics were performed and was told that they hook up a computer which produced a code related to the master cylinder. They could not explain why the computer gave them themaster cylinder code and did not offer to reinspect vehicle to determine actual cause.

I have a 2004 Toyota Sequoia my anti lock brakes,and traction control lights come on all the time which means that the systems are not working. Went to the dealer ship and was told it was the skid control ecu and it would cost $1804. 00 the truck has 54,275 miles on it. This should be covered by Toyota because with out the safety features not working accidents can happen.
