ABS, ESC, and brake indicator lights randomly display upon driving the vehicle. They display intermittently, sometimes after 1/4 mile of driving, other times after 25 miles of driving. They display on smooth or rough roads, with no apparent cause. While I have not yet had an accident or system fail, it is of concern because I Transport my daughter in this vehicle. On a vehicle that has 50,000 miles on it and other documented cases of this as well, I believe this is a cause for concern. I am not sure of the cause or the solution to this problem as of yet. The vehicle does not have to be in motion when the lights appear either. They appear at stop signs or lights, when driving slowly, or at highway speeds. I am unaware if the systems themselves stop working upon the indicators activation or not. I believe that this warrants more investigation and possibly a safety recall as ABS and ESC are safety features and brakes are (from my civilian perspective) a necessary function for the vehicles safe operation.

While driving in city ABS vsc brake warning lights came on with message to immediately take to dealer. Turned out to be speed sensor on right rear wheel. I have removed sensor and while there is no physical damage it appears to be an open circuit. Clearly a defect in product since the car is garaged and I live in a high desert environment. Effectively the ABS and vsc systems are disabled.

Toyota 2009 Venza systemic speed sensor failures: Right rear speed sensor 1/17/2015: Left rear speed sensor May 2013: Left front speed sensor April 2012 in each case, the antilock brake system (ABS) and the vehicle stability control (vsc) systems were disabled, creating hazardous vehicle operation, especially in snow/ice. Researching, I determined that no recall had been issued, but that knowledge of the defective speed sensors and that their failure disabled the ABS and traction control systems were common knowledge. I notified Toyota customer assistance center of my concern, on January 22, 2015 (Toyota case # [xxx]), and made formal request for full reimbursement of the charges for the third repair on the basis that Venza speed sensor failures are a systemic, recognized issue causing hazardous driving conditions, and clearly should have been the subject of a recall long past. I notified Toyota that the criteria for notification of the issue to the department of transportation, National Highway Traffic Safety Administration (NHTSA) were clearly met. Per United States code for motor vehicle safety (title 49, chapter 301), motor vehicle safety is defined as 'the performance of a motor vehicle or motor vehicle equipment in a way that protects the public against unreasonable risk of accidents occurring because of the design, construction, or performance of a motor vehicle, and against unreasonable risk of death or injury in an accident, and includes nonoperational safety of a motor vehicle.' Toyota rejected my request 3/10/15 on the basis that it did not meet the criteria of their new vehicle limited warranty, completely disregarding the stated concern. Given that Toyota has willfully chosen to not address the recall and hazard issues raised, this complaint is submitted. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
