Open the full vehicle complaint log (all categories)The contact owns a 2025 Ford F-150. The contact stated that while starting the vehicle, the engine revved, and while idling, there was a knocking sound coming from the engine. The vehicle was taken to the dealer and was diagnosed with bearing damage caused by a defective connecting rod and rod bearings, which caused the engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact researched online and became aware of NHTSA Campaign Number: 25V344000 (Engine and Engine Cooling); however, the VIN was not included. The manufacturer was informed of the failure by the dealer; however, the contact had not spoken with the manufacturer. The manufacturer opened a case for the failure. The failure mileage was approximately 1,000.
My 2025 F-150 Tremor (5.0 V8, 402A package with modular front bumper) has a large open area in the front bumper. Through this opening you can clearly see the front of the engine and related components. This appears to be a design issue rather than a one-off build problem. Other 2025 Tremor owners with the same 402A modular bumper are reporting the same concern and asking whether a cover is missing from the factory. My concern is that the exposed opening could allow rocks, road debris, or off-road obstacles to directly impact vital components at highway speed or when driving on rough/uneven surfaces. This may increase the risk of damage, fluid leaks, or sudden loss of power/steering if components are struck. It also appears inconsistent with typical under-engine protection on off-road-oriented trims. I am asking NHTSA to review whether this bumper configuration provides adequate protection for critical components on the 2025 F-150 Tremor and whether a design change or shield/plate is needed for safety.
