Toyota just issued a brake-related recall on the 2012 RAV4, 2012-2013 Tacoma, and 2012-2013 Lexus RX350. Looks like a buildup of oxide film in a brake actuator terminal can render Vehicle Stability Control, Traction Control, and ABS inoperative.

The problem seems to only affect vehicles built between March and December of 2012, which is 54,010 RX350s, 107,052 RAV4s and 100,052 Tacomas.

Here's the straight from Toyota, and the consumer briefing from the :

SUMMARY:

Toyota is recalling certain model year 2012 and 2013 Toyota Tacoma and Lexus RX350 vehicles and certain model year 2012 Toyota Rav4 vehicles. In the affected vehicles, the brake system contains a brake actuator that adjusts the fluid pressure of each wheel cylinder. An electrical component within the actuator may experience an increased resistance resulting in the illumination of various warning lights, including those for the Vehicle Stability Control (VSC) system, Antilock Brake System (ABS), and Traction Control system.

CONSEQUENCE:

If this occurs, these systems could become inoperative, reducing the directional control assistance, increasing the risk of a crash.

REMEDY:

Toyota will notify owners, and Toyota and Lexus dealers will update the software for the Skid Control electronic control unit, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Toyota at 1-800-331-4331.
