Back to Basics: Hyundai's Guide to the Classic Shoulder Check
TRENDING TSB
Owners of certain 2014-2018 Hyundai Santa Fe vehicles may experience Blind Spot Detection (BSD) or Blind-Spot Collision Warning (BCW) system performance issues or warning conditions, leaving drivers to rely on the antiquated combination of side-view mirrors and turning their heads. Hyundai Technical Service Bulletin 19-BE-011H addresses conditions that can cause BSD/BCW systems to malfunction or inconsistent operation, including potential calibration-related issues.
According to Hyundai, the problem isn't always a failed sensor. The system relies on radar sensors mounted behind the rear bumper, and their performance can be affected by collision damage, bent mounting brackets, blocked sensors, bumper deformation, or improper sensor alignment. Environmental factors such as tunnels, concrete barriers, large vehicles, and even heavy rain or snow can also interfere with operation.
Before concluding the sensors have developed a blind spot of their own, Hyundai recommends a thorough inspection and calibration process. The bulletin outlines procedures for checking sensor mounting locations, verifying sensor angles, measuring alignment, and recalibrating the system using specialized tools and scan equipment. The goal is to ensure the radar sensors are properly aimed and able to accurately detect vehicles approaching from adjacent lanes.
The detailed repair procedure is included in the TSB.
