NHTSA Complaint #11655655 — 2025 FORD E-450

The component that failed was the driveline on our RV. Specifically, the driveline was installed at an incorrect angle, which caused excessive vibrations and loud noises while driving at highway speeds. The improper driveline angle posed a serious safety risk to my family and others on the road. The vibrations were severe enough to affect vehicle handling and stability, especially at higher speeds. There was also concern that the continued stress could lead to mechanical failure or component separation, which could result in loss of control or debris on the roadway. The issue has been confirmed by a Ford RV technician, who verified that the driveline angle was outside manufacturer specifications. The vibrations could be consistently reproduced during test drives. The vehicle has not been inspected by the manufacturer, police, or insurance representatives at this time. There were no warning lamps or dashboard messages, but noticeable symptoms—including a strong vibration through the floor and loud droning noises—began immediately upon first highway use and persisted until inspection revealed the driveline misalignment.
