Service bulletin ITB21-012
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
INCORRECT FRONT/REAR SONAR SENSOR OPERATION SERVICE INFORMATION Sonar sensors use ultrasonic sound waves to detect objects, and determine short range distance to those objects. If a sonar sensor’s visible surface has been damaged or is partially, or totally, obstructed by mud/dirt, road debris, bugs, snow or ice, the sound waves that are being transmitted can be muted, redirected, absorbed, and not received. Possible causes of incorrect sensor (sonar sensor) operation: • Object not within the detection range of the sensors. • Sensor range sensitivity setting is set too sensitive, or not sensitive enough. • Objects that cannot be detected by the sensors. • Foreign material (mud/dirt, road debris, bugs, snow or ice, etc.) attached to any of the sensors, or their surroundings. • Damage to one or more of the sensors, or the area around the sensors. • Items installed around one or more sensor (e.g. Accessories or bumper protectors, etc.). • The vehicle ride height has been altered.
