Ram Promaster stalling problems

Filed Jul 30, 2026 · Engine · NC

The check-engine light came on my 2nd day of ownership (less than 100 miles driven by me, but 2032 miles on it when purchased new - RV conversion from Entegra Coach through LaMesa RV), on October 5, 2025. After diagnosis at a Ram dealership (Larry Miller Dodge Ram in Tucson AZ), they identified the code was misfire on cylinder 6, which caused low compression, with a root cause of the intake valves being improperly seated during manufacturing. The dealership replaced some cylinder and engine parts, but the issue recurred on Cylinder 4 after driving it about 5000+ miles, on June 13, 2026. Again, misfire check-engine code and loss of compression on cylinder 4. The engine ran very rough and had loss of power. The engine is still under investigation by another Ram dealership service department (Crest Auto World, Center Conway, NH). I have learned that loss of compression can cause the engine to stall, lose acceleration power (which it did), and potentially throw a rod and blow a hole in the engine. Since this was caused by a manufacturing defect, I am also concerned that there are other vans with this issue on the road.

The defective cowl and compartment cause water to leak into the engine bay, which saturates the engine and various components. The defect resulted in the crankshaft position sensor getting wet.
