NHTSA Complaint #11575726 — 2023 FORD F-150

Bought brand new truck in December 2023. Immediately the Air/AC/Heat would intermittingly malfunction resulting in inability to defrost windshield. This resulted in hindering the drivers visibility, automatic emergency braking, front camera visibility, and other safety features. If the AC/Heat malfunctions at a time of need for defrosting/defogging the windshield, it will put anyone in the vicinity of the moving vehicle at risk. Truck was taken into the dealership during this malfunctioning period 3 different times over 2 or 3 months. The first time a service technician diagnosed a failed module, module was replaced but did not fix the issue. The second time, the service manager and shop supervisor diagnosed a failed temp senser inside the HVAC system. Senser was reading below freezing levels, supervisor took a picture of the reading to show the electrical tech. This would cause the HVAC system to give incorrect readings to other components. After further diagnosing from the dealerships master electrical tech during the second time, tech deemed it to need an update and recalibration. Update & recalibration was completed but did not fix the issue. during the third time, the Ford Engineer, shop supervisor and master electrical tech inspected the truck and BELIEVED replacing HVAC would fix issue. It is unknown if issues were diagnosed to be failing or if it a guess. HVAC has not been replaced due to no known acknowledgement from Ford into this issue. They will replace HVAC with the exact SAME part. After discussing with other Ford owners, the same issue occurs in 2023 Ford Expedition. Multiple videos were taking over this 2–3 month timeframe, before and after multiple attempts by dealership attempting to fix the issue. Vehicle has not been inspected by police, insurance reps, or others. Warning lamps/messages displayed "Front Camera Low Visibility Clean Screen" during period of malfunctioning.
