Brake Sensor Problems of Toyota Sequoia - part 2

We were driving down the hill and the traction control system went crazy we skidded out and then the abs and traction control/slip lights went on. They stayed on until we took it to the dealer and they replace some brake sensors that were corroded. On the way home it happened again. The traction control computer was reporting that there were still bad sensors, but the sensors were fine, so they replaced the entire traction control computer. After a week in the shop it finally came back working. A traction control system should not throw your car out of control and run you off the road. The dealer said that they had not seen so much corrosion under a vehicle before. They said that the frame, exhaust, spare tire, and brake components as well as various other electrical components looked to have what they would call excessive corrosion. They said I should take it up with whom I bought it from. I think this is the same problem as the tundras are having with corrosion and should be looped into the same investigation. The Sequoia, I was told when I bought it, was designed on the same frame, and drive train as the tundra which would explain why the corrosion is effecting similar braking systems and the spare. I would love for someone to investigate this. I would have hated for anything to happen to my family which was in the car with me.

The contact owns a 2001 Toyota Sequoia. Whenever the contact applies the brakes he noticed that the abs system and traction control would activate regardless of the driving surface, the contact also noticed that he could hear a sound similar to leaking air coming from the brakes. The vehicle was taken to the dealership where the contact had the abs sensor and all components of the braking system replaced, however the contact still notices the leaking air sound coming from the brakes. The vehicle has not been diagnosed since it was last serviced. The current mileage is approximately 138000 and failure mileage was approximately 78000.

"vsc trac" dash light flashed intermittently and then stayed lit at 45,000 miles. Per Toyota dealer service department, the vehicle skid control (vsc) computer and steering angle sensor failed. As a result of vsc computer failure, the vehicle's antilock brake system and vehicle skid control system are disabled.

Brake system will grab and throw car into skid, but parts are failing intermittently. The switch on the dashboard does not shut it off. Consumer had no control of vehicle. It has been in the repair shop, and found out steering angle sensor was bad, and replaced it. Also, computer was defective. The vehicle's computer was replaced also. The technician could not confirm what failed first, why either failed, or why he could not find any trouble over one year ago, when consumer noticed blinding lights on the dashboard. The consumer feels that this is a safety hazard because drivers do not have control over this active 4 wheel drive system. Also the dash control will not shut off vsc (vehicle skid control), nor any other fuse, switch, wire, or other vsc's.

Concern started with a vsc and traction control warning lights in instrument cluster coming on and off in an intermittent fashion without pattern or external cause. The warning lights would not remain on but instead would glow for a brief bit of time and then extinguish. The vehicle did exhibit a spontaneous deceleration on several occasions while operating at low speed (less than 20 mph) and on level, smooth ground. The episodes were brief and normal brake operation return immediately once speed dropped to approximately 5 mph. In the decades that I have operated this automobile, the warning lights went from lighting intermittently to being illuminated continuously; the spontaneous breaking has seemingly ceased since these lights have remained on. Dealership and factory were informed of this concern with each service visit. Dealership response was that they were unwilling or unable to diagnose an intermittent concern. Once the lights remained on, I was initially informed that they suspected a defective yaw sensor and more recently, malfunctioning brake booster components; warranty period had lapsed and no extension was offered. Attempts to correctly diagnose and repair this concern have dragged on for 10 years with dealership and factory position that repairs, be they diagnostic (the yaw sensor replacement) or definitive (booster and brake system), were not warranty issues despite their intermittent presentation during the warranty period. My periodic practical testing of the brakes demonstrates that the abs system functions properly despite warning light indications to the contrary. Current dealership estimated cost to replace brake booster and actuators is $3800 with a 12 month warranty. Toyota USA's position is this is not a warranty issue as of April 2013.
