Complaint Summary

VISIBILITY/WIPER

Owner Narrative

Description of the Issue: When full windshield defrost is selected—using either the infotainment system or physical HVAC controls—the system does not direct full airflow to the windshield. Instead, heated air is split between the windshield and floor vents, reducing airflow and heat at the windshield edges. As a result, ice forms and remains on the driver’s side windshield edge, beginning around the 11–12 o’clock steering wheel position and extending to the windshield edge. This occurs during cold conditions and restricts driver visibility, creating a safety hazard while driving. Safety Impact: The driver is unable to clear ice from the windshield edges, limiting visibility of adjacent lanes, pedestrians, and roadway conditions. When defrost is needed most, the system does not perform as required, preventing the driver from maintaining safe visibility. Inconsistent Operation: The HVAC/defrost system operates inconsistently under similar conditions. I have video evidence showing the system working correctly at times and failing at other times. In multiple cases, the only change was shutting the vehicle off and letting it sit. In one instance, the defrost later worked correctly the same day when ambient temperatures were warmer, suggesting a possible temperature-related or control issue. Videos documenting this behavior are available, including videos posted on YouTube. Additional HVAC Control Issue: The HVAC system will randomly set the temperature to 76°F and become unresponsive for approximately one minute. During this time, the driver cannot change any HVAC settings, creating distraction and preventing timely adjustment to address fogging or icing. This behavior is also documented on video. Repair Attempts: The vehicle has been taken to two RAM dealerships, and multiple parts have been replaced under warranty. The issue remains unresolved. A customer service case was also opened with RAM, but the HVAC and defrost issues have not been corrected.
