Park assist sensors are part of the park assist system, just one of many advanced driver assistance systems (ADAS) found on vehicles today. Damaged sensors are typically replaced and may require painting to match the vehicle. Vehicle makers often provide information on the painting of new sensors. Some vehicle makers do not recommend refinishing sensors with minor finish damage because excessive paint thickness may adversely affect the operation of the park assist system. However, other vehicle makers allow refinishing and provide guidelines. Let’s see what Hyundai has to say.
Per the Hyundai Repairing Front And Rear Bumpers With Corner Radar Units Or Ultrasonic Sensor position statement:
- "Refinishing or touch-up paint application may NOT be done on the ultrasonic sensors. If any damage, contamination, or paint overspray occurs on the ultrasonic sensors, they must be replaced according to shop manual procedures."
- "When ordering the correct ultrasonic sensors, refer to the parts catalog for the correct part number that corresponds to the exterior color of the vehicle. The replacement ultrasonic sensors are pre-painted from the supplier."
Improper refinishing of the sensor might lead to sensor malfunction. Follow OEM procedures and warnings to help ensure a complete, safe, and quality repair.
