Brake Sensor problems of the 2001 Toyota Sequoia

Accelerating onto highway the car made grinding noise and pulled to left as well as suddenl braking. It was almost a disaster but car in next lane veered away and I pulled onto shoulder. I had been told the yaw sensor needed to be replaced but was not available anywhere. When I looked online I saw NHTSA did not feel it was a dangerous failure, but it read as more of an inconvenient problem so I was comfortable trusting them and drove it after the dealer had said it couldn't get the part. Why was Toyota able to declare a part obsolete that obviously is important to my safely operating the vehicle? how can. The NHTSA possibly think this is not a safety issue?.

Tl the contact owns a 2001 Toyota Sequoia. While driving approximately 40 mph, the variable speed control malfunctioned. The contact stated that the abs and traction control indicators illuminated without warning. The contact depressed the brake pedal, while turning, and a hard vibration occurred. The contact stated that the vehicle returned to normal immediately afterwards. The contact parked the vehicle and contacted coos bay Toyota (2001 n bayshore drive, coos bay, oregon 97420, (541) 267-3121) where it was diagnosed that the yaw rate sensor was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The VIN was unavailable. The failure mileage was approximately 190,000.

My complaint stems from the vehicle stability control (vsc) issue that commonly plagues the 2001-2001 Toyota Sequoia. As many others have filed complaints over this vsc issue, mine is no different. My Sequoia, a 4x4 sr5 with 160k miles, works flawlessly other than the vsc lights being constantly illuminated while driving. The results of the malfunction, possibly from the yaw rate sensor, present a momentarily loss of power and random unexplained steering events. The only way to temporary clear the vsc lights and the effects of the malfunction is to completely stop the vehicle, turn off the ignition and restart the vehicle. I fear a loss of control of the vehicle while my wife and kids are driving at highway speeds. I would like to see Toyota issue a formal recall or pay for a new yaw rate sensor and the consumer pays the labor. Other than the vsc issue, the Sequoia is a great vehicle overall.

While driving along at ~40mph, car jeered to the right and made a noise as if the anti-lock brakes were pumping on the right side of the vehicle. The vsc & trac lights came on. Vehicle then drove normally until the ignition was turned off. Once the vehicle was started, the same incident occurred repeatedly making it unsafe to operate. Took vehicle to the Toyota dealership and was told I needed a new yaw sensor - $558.

Tl * the contact owns a 2001 Toyota Sequoia. The contact stated that while driving 70 mph, the vsc warning lamp illuminated. The contact mentioned that when the failure occurred the steering wheel locked momentarily. The vehicle was taken to the dealer. The technician diagnosed that the ecm needed to be reprogram. The vehicle was repaired and failure recurred shortly after the leaving the dealer. The vehicle was taken back to the dealer and the technician stated that the yaw rate sensor was defective and needed to be replaced. The manufacturer was not made aware of the failure. The vehicle was repaired. The failure mileage was 143,000 and the current mileage was 144,000. . . Updated 08/11/14.

Recently had new tires installed, while accelerating up freeway on ramp I could feel power being taken away, looked down and skid control light was lit up. Asked mechanic about it and recommended zero point calibration to rest sensors for steering yaw and pitch. After zpc vsc trac and vsc off lights were on. Code pulled c1231 steering angle. Zpc again. Code and lights still, code will not clear with Toyota intelligent 2 scanner. Monitoring steering sensor with scanner show both positive and negative numbers with zero at wheels straight. Mechanic want to change out spendy vsc cpu and translate cpu and says that is no guarantee to fix. I am driving it with lights one due to unable to pay $2k for something out of know where and no part physically broke to promote. In looking around I see this is not an isolated issue.

The dealer diagnosed that the variable skid control or yaw sensor needed to be replaced. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure and current mileage was 114,000.

While driving at a rate of 70mph the vsc trac and trac control warning lights came on. The car decreased in speed and veered to the right, causing me to momentarily loose control of the car. Per owner's manual took car into dealership for diagnostic. Per codes obtained via diagnostic dealer suggests replacing yaw control sensor and ecu. After researching this issue myself it seems to bean issue with the 2001 Sequoia and its ecu, yaw control sensor, and the steering angle sensor that could result in serious harm or injury if not corrected.

The contact owns a 2001 Toyota Sequoia. While driving 65 mph there was a loud thump in the right front passenger side wheel area, automatically the right front brake was applied . The vsc off and traction lights illuminated on the instrument panel. The contact depressed the brake pedal and released it, which allowed the front passenger side brake to release and the vehicle to drive normally again. Four days prior to the failure, the contact noticed that the vsc off and traction lights would illuminate while driving, but then dim after the vehicle was restarted. The vehicle was taken to the dealer and they disabled the vsc sensor to prevent the failure from recurring. The current mileage was 47,000 and failure mileage was 44,700. Updated 09/10/08.

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.

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.
