Summary

Non-Toyota-Approved Modification - Owner Acknowledgment Form: Non-Toyota-Approved Modification - Owner Acknowledgment Form Certain 2018 -2019 MY Tacoma and Tundra - Millimeter Radar Wave Sensor. Your vehicle is involved in Special Service Campaign K0B. It is equipped with a Pre-Collision System (PCS) that may automatically apply the brakes if the system detects a potential collision. Due to the mounting of one of the system?s sensors, it is possible for water to enter the sensor. This can lead to PCS deactivation or inadvertent brake activation resulting in brief and limited vehicle slowing. The remedy involves an update to the PCS software and application of sealer to the millimeter wave radar sensor in the front grille. Also, in the rare case that the vehicle is currently exhibiting the condition, dealers will diagnose the sensor and replace it, as necessary, FREE OF CHARGE. However, because your vehicle has non-Toyota-approved modifications as noted below, PCS and Dynamic Radar Cruise Control (DRCC) may not operate as designed regardless if this free remedy is performed. For example: ?PCS may activate even if a collision is not likely. ?PCS may not recognize a vehicle or a pedestrian when a preceding vehicle or pedestrian is ahead.

Owners of these vehicles have filed 48 complaints in the driver assistance category.
