Complaint Summary
BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
Owner Narrative
Bronco wire corrosion cross traffic refers to a known issue where wiring under the rear bumper, often for the blind spot/cross-traffic sensors, chafes, frays, and corrodes, causing system faults and failures, sometimes due to design flaws or environmental exposure to salt, requiring inspection and repair of the harness. This problem triggers error messages like "Cross Traffic System/Blind Spot System Fault" in the instrument cluster, impacting safety features, with potential fixes involving harness repair, protective sheathing, or sensor replacement. My carâs wiring was corroded due to this flaw and required a repair exceeding $1,000.
