Mack affected vehicles have a switch to release the fifth wheel latch that may invertently be pushed and cause the trailer to unintentionally disconnect from the tractor after the parking brake has been released.
The short version
Mack Trucks, Inc. reported a problem with the trailer hitches fifth wheel assembly. Here is what owners need to know.
The affected vehicles have a switch to release the fifth wheel latch that may invertently be pushed and cause the trailer to unintentionally disconnect from the tractor after the parking brake has been released.
An inadvertent decoupling of the trailer from the tractor may increase the risk of a crash.
Mack will notify owners, and dealers will install a secondary action that operators will need to activate before the fifth wheel will release, free of charge.
