NHTSA Complaint #11621840 — 2025 KENWORTH T380

Flowmark of Kansas city Missouri built my company a truck. When adding an upfit body (AKA septic tank skid unit) there was no motor carrier calculation done for the rear axle weight. Upon my arrival to pick up the truck I could see that the rear axle was overloaded. Addressed with flowmark and they admitted a calculation had not been done. They moved the unit forward to the correct position, during this time no care was taken when drilling the new mounting holes, in which case resulted in 21 holes too close together. This truck is not safe, nor does it meet the manufactures recommendations. I took the truck to a Kenworth dealer and they have provided the documentation that says this truck is not correct and needs the entire frame of the truck replaced. Flowmark wants to bring the truck back to KC from Ohio and weld the holes shut and paint them and send the truck back. This again is against Kenworth's recommendations.
