- Filed Aug 22, 2025Failure Dec 1, 2024101,185 milesFoss, OKRadar1 injured
The contact was the operator of a 2025 International LT62F company vehicle. The contact stated that on several occasions while driving with another truck in front of the vehicle that was attempting to slow down from at least 200 feet away, the automatic braking system erroneously activated, causing a false positive reaction with the brakes warning system detecting a possible crash with a brick wall, causing the Autonomous Braking and Lane Assist system to slam on the brakes of the tractor and the trailer. The contact stated that the force caused the vehicle to slide to the left, with the momentum of the trailer being hauled. There was no accident reported. The contact sustained a strain of the right shoulder from the seat belt locking. Medical attention was not required. The vehicle was taken to an independent mechanic, where it was diagnosed, and the contact was advised that the radar was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 101,185.
