King Pin May Fail Causing Trailer to Detach
A detached trailer cannot be controlled and may overturn or obstruct the road, increasing the risk of a crash.
Semi-trailer owners are advised to inspect for any coupling plate or king pin damage prior to operation. If damage is found, owners should not operate the trailer until it has been repaired. ABS authorized service facilities will replace the coupling plates, free of charge. Owner notification letters were mailed March 2, 2023. Owners may contact ABS customer service at 819-879-6216.
