August 17, 2024 makes a year of when i purchased my 2018 international LTA26 6X4 . The vehicle has been to several shops (Westrux International) where i paid for service that ended up being a recall for (Velocity calibrations) which did not fix the problem. (Southwest) is the next shop i took my truck to However, the mechanics were still unable to determine the cause of failure. I have researched on NHTSA and found recalls (Connecting Rod May Crack and Cause Engine Failure) that relate to my problem i'm having with my truck.
Tl* the contact leased a 2018 international lt a26 truck. The contact stated that the steering wheel, steering box failed and caused the truck to swerve.
