Ford's October On Target Highlights Why OEM Glass Matters for Camera-Equipped Windshields

The second week of October 2022 brought a direct manufacturer communication that resonated throughout the auto glass trade: Ford's October edition of On Target made an explicit case for the use of original equipment glass on vehicles equipped with forward-facing safety cameras—a statement that carried both technical weight and commercial implications for shops and insurers.

Ford's publication noted that OEM glass is manufactured to match the optical properties specified during vehicle development, including curvature tolerance, refractive index, and distortion characteristics. When an aftermarket windshield with even slightly different optical properties is installed, the forward camera may experience changes in perceived image geometry that affect the accuracy of lane detection, object recognition and distance estimation—the core functions of modern ADAS.

The practical stakes were significant: a windshield whose optical properties differ from OEM specification can cause a calibrated camera to behave as though it is uncalibrated. Shops that performed technically correct calibration procedures using aftermarket glass that did not meet OEM optical specifications might find that the resulting system performance was below the standard the customer expected—and potentially below the minimum required for safe ADAS function.

Ford's guidance stopped short of prohibiting aftermarket glass but clearly framed OEM glass as the preferred and safest choice for ADAS-equipped vehicles. For shops navigating the OEM versus aftermarket debate, the October On Target gave them OEM-sourced language to use when explaining the recommendation to customers.

Insurer direct-repair program administrators were also watching the Ford guidance with interest. Programs that required OEM-specified materials for ADAS-equipped vehicles would be on solid ground citing the manufacturer's own published guidance. Programs that had not yet adopted OEM glass requirements for camera-equipped windshields faced an increasingly difficult position as OEM guidance became more explicit.

Ford's October guidance also had implications for shops that had not previously considered how their aftermarket glass selection choices were documented. A shop that could demonstrate—through vendor records or supply chain documentation—that the aftermarket glass installed on a Ford vehicle met the optical specifications referenced in Ford's guidance was in a materially stronger position than one that could only show the brand name and part number of the product used. Optical specification documentation from glass suppliers was becoming a relevant qualification document in 2022.
