NHTSA Complaint #11648025 — 2017 RAM PROMASTER

The windshield cowl on this vehicle is poorly designed, allowing water intrusion from multiple points. This is not a minor leak but a severe design flaw that creates immediate and dangerous safety hazards while driving, particularly at highway speeds. The most critical issue is water pouring directly onto the serpentine belt and pulley system. While driving at highway speeds in heavy rain, I lost power steering after water intrusion caused the belt to slip. This sudden loss of steering assist made the vehicle extremely difficult to control, especially in traffic and during turns. Another major safety risk is water intrusion onto the engine fuse box. While driving at highway speeds, water poured into the fuse box, causing electrical shorting. This led to severe overheating that burned my windshield wiper wiring, making the wipers inoperable and drastically reducing visibility. Surrounding wires also melted, posing a significant fire hazard. The sudden electrical failure and loss of visibility created an extremely dangerous situation. Additionally, water pooling on the transmission can drain into the breather hole, allowing significant water intrusion into the transmission fluid. This can cause erratic shifting, transmission failure, or complete power loss. At highway speeds, this can lead to sudden deceleration or loss of acceleration, putting drivers and others at serious risk. This issue has been experienced by multiple owners and confirmed by independent service centers. It is not a DIY repair—the defective cowl design allows excessive water ingress. There are no warning lights or messages before failure, only sudden and dangerous symptoms once water intrudes. This is a major safety concern, particularly at highway speeds, where sudden power steering loss, electrical failure, or transmission issues can lead to catastrophic consequences. Immediate investigation and corrective action are necessary to prevent accidents, injuries, or fatalities.
