NHTSA Complaint #11660301 — 2017 RAM 1500

The diesel EGR Cooling System prematurely failed on a vehicle with low mileage and repaired at owner's expense. This defect allows pre-heated, vaporized coolant into the EGR system while the engine is running. In certain circumstances, this mixture interacts with other hydrocarbons and air in the system, potentially resulting in combustion within the intake manifold, which may lead to a vehicle fire. A vehicle fire may increase the risk of injury to occupants and persons outside of the vehicle, as well as property damage. Other than noting black residue in the coolant reservoir, there is no warning or notification to the owner that this dangerous condition had occurred, and that their safety may be at risk if not monitored. Previous model years had this same defect and are covered by Safety Recall VB1 / NHTSA 19V-757 Diesel EGR Cooler.
