Brake Sensor Problems of Toyota Scion Xb

While driving on snowy and salted roads, the brake, abs, and vsc lights all came on at the same time. They remained on while driving on those same snowy and salty roads. The next day they eventually went off. Weeks later they came on again in wet weather and remained on. The local Toyota service center duplicated the issue and pulled the diagnostic codes c0210 & c1238. The Toyota service center said the entire hub and bearing assembly had to be replaced as the internal abs sensor which they said was at fault was not sold separately and only came as part of the hub and bearing assembly kit. Their quote to repair this issue was $915 for the replacement of one hub and bearing kit! this is ridiculous. Brake sensors should not fail due to snow, salt, or water coming into contact with them. This is a dangerous flaw in the design of this vehicle and one that is not commonly found with other makes and models, but is commonly reported all over the internet from other owners of Toyota's Scion Xb. Toyota should issue a safety recall for this vehicle and cover the cost to replace the sensors with ones that do not fail due to weather conditions.

Vehicle driven by daughter. 45 mph road. Two (2) vehicles in front of her. 1st vehicle made an abrupt right turn, causing vehicle #2 to abruptly decrease (braking) speed, which cause vehicle #3 (scion) driver to react quickly and brake. During braking, all four (4) wheels locked and vehicle skidded straight forward. Angle of skid shows both wheels sides were straight with an approximate two (2) to three (3) degree angle offset to the right; may be due from curvature of the road. Both skid marks were completely solid and both tracks were in a straight line. Upon front end impact with vehicle #2 in front of the scion, the following issues are of concern: 1. Front driver and front passenger airbags did not deploy. Not know if impact (deceleration) was high enough to activate. However, visual inspection of vertical sensor support beams (both left and right) are significantly displaced and bent. 2. Seat belt restraint system (front - driver and passenger): the seat belt restraint system appeared not to function as designed. According to the driver and passenger, both were wearing their seat belts. Upon impact, the driver's lower body propelled forward and her knees impacted the lower dash assembly. Additionally, her upper body was propelled forward, the seat belt did not lock, and then braced herself with hands and arms to prevent her head from striking the steering wheel. Additionally, the right front passenger experience the same propelling of lower and upper body with out the seat belt locking. He also had to brace himself from striking the dash. Called scion corporation headquarters on 14 September and opened a new case; stating exactly was stated above. Thank you for what your agency does and any assistance you can provide.

The contact owns a 2008 Toyota Scion Xb. While driving approximately 30 mph, the abs, traction control and stability control warning indicators illuminated on the instrument panel. In addition, the parking brake began to illuminate. The malfunction occurred intermittently. The vehicle was taken to an authorized dealer who stated to the contact that the rear driver side abs sensor connector was faulty and would need to be replaced. The vehicle had not been repaired. The manufacturer was not notified of the problem. The approximate failure mileage was 69,700.

1. Driving on snow covered roads + salt several times + low temps lower then 30f 2. Abs+trac+vsc+brake trouble indicator all come on with the vsc light blinking, this occurres after snowfall and the roads being salted. Loss of traction control, vehicle stability control, anti lock brakes, and electronic brake distribution. Causing the car to loose all active safety features. 3. Anti-lock electric connectors were removed cleaned with electronic cleaner and brushed to remove significant corrosion from the abs sensor and plug. This hars resolved the problem for the moment.

The anti-lock brake system (abs), visibility stabile control (vsc) and traction control warning light, and brake indicators remain illuminated on the instrument panel. The repair center has advised me on different repairs that are inconsistent. One repair option is a faulty sensor in one of my rear wheels that needs replacing. The other repair was that the wheel bearing was bad on the left front wheel and that when fixed would re-set the sensor lights. This is an obvious flaw in the design of this vehicle and Toyota should make every effort to repair the sensor problem. I an not sure why the bearings need to be replaced at this time at over $500. 00/wheel. The brake pads, rotors, calipers and other brake parts need frequent replacement at a very high cost.

Dashboard warning light for brakes, abs, and tcs light up randomly so the driver cannot determine if there is a problem with the brakes or it is a false warning. The car was examined by don joseph Toyota/scion in kent, ohio on March 1, 2010. They said the right rear sensor was malfunctioning and it would cost approximately $700 to repair it because the car has 53,000 miles on it and is out of warranty. This failure has been occurring intermittently for one month.
