Hyundai Elantra (CN7): Blind-Spot Collision Warning (BCW) / System disabled
When the rear bumper around the rear corner radar or sensor is covered with foreign material, such as snow or rain, or installing a trailer or carrier, it can reduce the detecting performance and temporarily limit or disable Blind-Spot Safety system.
If this occurs, the ‘Blind-Spot Safety system(s) disabled. Radar blocked’ warning message will appear on the cluster.
The system will operate normally when such foreign material or trailer, etc. is removed, and then the engine is restarted.
If the system does not operate normally after it is removed, we recommend that the system be inspected by an authorized HYUNDAI dealer.
