I was traveling northbound on [XXX], just before [XXX], at approximately 35 mph on dry asphalt in my 2015 Ram 1500 3.0L EcoDiesel just after refilling the fuel tank with 13.999 gal. of diesel fuel. While the vehicle was being driven both fuel-tank retention straps broke. The fuel tank dropped from its retained position and was observed resting on the asphalt beneath the vehicle. The vehicle lost all power causing a near-miss incident while attempting to navigate out of traffic. After coming to a stop, the vehicle was moved to the side of the road and parked just east of [XXX] on [XXX]. Passenger and eyewitness [XXX] experienced the entire incident and also observed the fuel tank beneath the vehicle and the broken straps. The vehicle could crank but would not start; and the fuel lines and electrical supply were both damaged. The check-engine light illuminated, as well as the fuel low and fuel sensor fail messages occurred during and after the incident. AAA towed the vehicle directly to Byers Chrysler Jeep Dodge Ram on XXX. Dealer repair order XXX was opened XXX, and the vehicle was physically inspected on XXX. The dealer documented: “VERIFIED CUSTOMER CONCERN. CHECKED AND FOUND REAR FUEL TANK STRAP MOUNT IS RUSTED OUT. NOTHING TO HOLD TANK IN VEHICLE.” The dealer further documented that the vehicle “NEEDS FRAME OR REPAIRED FOR REAR FUEL TANK STRAP.” No recall repairs could be made; therefore the disabled vehicle was returned. The concern is that failure of the fuel-tank retention system caused the fuel tank to drop onto the roadway while the vehicle was moving. The dealer subsequently found that the rear fuel-tank strap mounting area was rusted out and that there was “NOTHING TO HOLD TANK IN VEHICLE.” I request that the federal safety agency investigate whether corrosion at the fuel-tank strap/frame attachment area can progress to the point that the fuel tank can no longer be safely retained.

There is a known issue about exhaust manifolds for my year model truck. A ram technician said in 2019 mopar created a new exhaust manifold for my truck that would be less likely to create soot buildup and warping in the exhaust manifold. In 2021 my EGR was replaced because of a recall but now my exhaust manifold has failed and needs to be replaced out of pocket even though it’s been a known issue and there was a remedy already made to alleviate the issue. Now because of soot buildup my throttle is limited until I have it fixed. But driving to a dealership is too far to be diagnosed as there has been cases of fires occurring when this issue occurs.

I am submitting this complaint to report a serious safety defect involving a high-pressure fuel system failure that occurred shortly after recall service was performed by an authorized dealership. The failure created a significant risk of engine compartment fire and potential loss of vehicle control. On March 25, 2025, my vehicle underwent recall service at Hall Ram Dealership for replacement of the high-pressure fuel pump. This repair required removal and reinstallation of the high-pressure fuel supply lines. These lines are torque-to-yield, single-use components that must be replaced once removed to ensure proper sealing under high operating pressures. On April 7, 2025, while driving at highway speed, the high-pressure fuel line connected to the pump suddenly ruptured. This resulted in an uncontrolled release of fuel into the engine compartment, creating an immediate safety hazard. Atomized fuel was exposed to high-temperature engine components, significantly increasing the risk of ignition and fire. The failure also posed a risk of sudden engine power loss. The vehicle required emergency towing. A review of the March 25 service invoice shows no documentation that the high-pressure fuel lines were replaced. This strongly suggests the original single-use lines were reused, contrary to OEM standards and accepted repair procedures. Reuse of these components can lead to sealing failure, fatigue, and rupture under pressure. This incident raises concerns regarding compliance with federal safety regulations, including 49 U.S.C. Chapter 301 and FMVSS No. 301 governing fuel system integrity. A fuel line rupture under normal operating conditions indicates a critical safety defect and possible improper execution of a recall remedy. I request that the federal safety agency investigate whether authorized repair facilities are properly following required procedures during recall repairs, including replacement of single-use fuel system components.
