Refinishing Park Assist Sensors: Hyundai
I-CAR · March 7, 2025 · Hyundai
Summary
This article outlines Hyundai's strict policy regarding park assist sensors, stating that refinishing or touch-up paint application is not permitted on ultrasonic sensors. If a sensor is damaged, contaminated, or has paint overspray, it must be replaced with a pre-painted sensor ordered from the parts catalog to match the vehicle's exterior color.
What to do on the job
Do not refinish or apply touch-up paint to Hyundai ultrasonic sensors; replace any damaged, contaminated, or oversprayed sensors with pre-painted OEM replacements.
How to use it
Use this document to justify the cost of replacing a contaminated or damaged ultrasonic sensor rather than attempting to refinish or clean it. It also supports the necessity of ordering pre-painted OEM sensors by part number to match the vehicle's exterior color, rather than painting raw sensors in-house.
