Automatic Emergency Braking problems of the 2019 Subaru Impreza

2019 Subaru Impreza has experienced intermittent and now persistent failures involving the factory eyesight driver assistance system. Prior to complete failure, the eyesight system would randomly disable and re-enable while driving. Adaptive cruise control and related safety features became unreliable and would intermittently stop functioning. The issue worsened over time and eventually resulted in repeated “eyesight off” warnings and multiple system fault messages. Vehicle diagnostic scans showed repeated u1235 “lost communication with eyesight” faults across multiple modules, including abs, steering, transmission, and instrument cluster systems. Additional communication and airbag indicator-related faults were also present. The windshield was recently replaced due to a crack located near the eyesight camera area. Subaru service personnel stated that eyesight systems are extremely sensitive to windshield specifications and calibration requirements, and that aftermarket windshields may prevent proper operation or calibration of the system. Subaru also indicated that eyesight calibration equipment is highly specialized and expensive, and that repair costs may not be practical relative to the vehicle value. Despite attempts to reset the vehicle systems and inspect the issue, the eyesight system continues to malfunction and remains disabled. Because eyesight controls important driver assistance and collision-avoidance features including adaptive cruise control, forward collision warning, lane departure warning, and automatic emergency braking, this issue creates significant safety concerns. The intermittent nature of the failure, repeated communication faults, and inability to reliably restore system operation raise concerns regarding the long-term reliability and serviceability of Subaru eyesight systems.
