The auto-glass & collision repair industries bear a disproportionate burden because every windshield replacement on an [[Advanced driver-assistance system|ADAS]]-equipped vehicle requires camera recalibration that the SGW blocks without active internet authentication.<ref name="rdn-adas">{{Cite web |url=https://www.repairerdrivennews.com/2026/03/04/industry-responds-to-federal-bill-requiring-nhtsa-guidelines-for-adas-calibrations/ |title=Industry responds to federal bill requiring NHTSA guidelines for ADAS calibrations |author=Teresa Moss |publisher=Repairer Driven News |date=2026-03-04 |access-date=2026-04-04}}</ref> The Federal Trade Commission found "scant evidence to support manufacturers' justifications for repair restrictions" in its 2021 report to Congress, & the GAO confirmed in 2024 that independent shops face repair information limitations resulting in fewer choices & higher costs for consumers.<ref name="ftc-nixing">{{Cite web |url=https://www.ftc.gov/reports/nixing-fix-ftc-report-congress-repair-restrictions |title=Nixing the Fix: An FTC Report to Congress on Repair Restrictions |publisher=Federal Trade Commission |date=2021-05 |access-date=2026-04-04}}</ref><ref name="gao">{{Cite web |url=https://www.gao.gov/products/gao-24-106633 |title=Vehicle Repair: Information on Evolving Vehicle Technologies and Consumer Choice |publisher=Government Accountability Office |date=2024-03-21 |access-date=2026-04-04}}</ref>

In July 2015, security researchers Charlie Miller & Chris Valasek remotely hijacked a Jeep Cherokee through its Uconnect cellular connection, demonstrating the ability to control steering, brakes, & transmission from a laptop miles away.<ref name="jeep-hack">{{Cite web |url=https://fractionalciso.com/the-groundbreaking-2015-jeep-hack-changed-automotive-cybersecurity/ |title=The Groundbreaking 2015 Jeep Hack Changed Automotive Cybersecurity |publisher=Fractional CISO |access-date=2026-04-04}}</ref> FCA recalled 1.4 million vehicles in response.<ref name="jeep-recall">{{Cite web |url=https://www.computerworld.com/article/1628895/chrysler-recalls-14m-vehicles-after-jeep-hack.html |title=Chrysler recalls 1.4M vehicles after Jeep hack |publisher=Computerworld |date=2015 |access-date=2026-04-04}}</ref> Manufacturers cite this incident as the justification for SGW.<ref name="alliance-r2r" /> However, Miller & Valasek exploited the vehicle's cellular telematics connection, not the physical OBD-II port.<ref name="jeep-hack" /> The SGW gates the physical port that a technician plugs a scan tool into while standing next to the vehicle. The FTC noted in its "Nixing the Fix" report that manufacturers' cybersecurity justifications for repair restrictions lack empirical support.<ref name="ftc-nixing" />

Bypassing the SGW requires a challenge-response protocol managed by a cloud server:<ref name="eti-overview">{{Cite web |url=https://etools.org/wp-content/uploads/2024/09/AutoAuth-High-Level-Overview-Ver10.pdf |title=AutoAuth High Level Overview |publisher=Equipment and Tool Institute |date=2024-09 |access-date=2026-04-04}}</ref>

Mobile technicians working in rural areas, parking garages, or anywhere with poor cellular coverage can't complete the ADAS recalibration. The windshield is physically installed, but the safety system is disabled because the scan tool can't reach AutoAuth's server. No offline authentication mode exists.<ref name="adasdepot" /> The technician must either leave the vehicle with uncalibrated ADAS (a liability risk), have the customer drive to a location with internet service (shifting the burden to the consumer), or return later at additional cost.

ADAS calibration requires manufacturer-specific physical target boards: large panels with geometric patterns & reflectors that the camera system uses as reference points during the calibration procedure. There's no universal standard across manufacturers. A shop that calibrates cameras for Toyota, Honda, Stellantis, Ford, & Hyundai needs separate sets of targets for each, plus alignment frames & fixtures.<ref name="rdn-adas" />

If a technician replaces a windshield but can't bypass the SGW to recalibrate the ADAS, the vehicle may misinterpret road data. Documented consequences include false lane departure warnings, failure to detect pedestrians, & inappropriate deployment of automatic emergency braking.<ref name="rdn-adas" /> Handing an uncalibrated vehicle back to a consumer exposes the independent shop to legal liability in the event of an accident. The H.R. 6688 (ADAS Functionality & Integrity Act), approved by a House subcommittee in February 2026, would give NHTSA authority to develop ADAS calibration guidelines & require manufacturers to publish calibration procedures & validation metrics.<ref name="rdn-adas" />

EU Regulation 2018/858 mandates non-discriminatory access to OBD & repair/maintenance information (RMI) for independent operators as a condition of vehicle type-approval.<ref name="eu-reg">{{Cite web |url=https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX:02018R0858-20240701 |title=Regulation (EU) 2018/858 - Consolidated |publisher=EUR-Lex |date=2018-05-30 |access-date=2026-04-04}}</ref> The Motor Vehicle Block Exemption Regulation (MVBER) was extended to 2028, maintaining these access requirements.<ref name="ecj-analysis" />

In October 2023, the European Court of Justice ruled in Case C-296/22 (Carglass/ATU v. Stellantis Italy) that manufacturers can't require personal registration, internet connection to manufacturer servers, or paid subscriptions for OBD access beyond what Regulation 2018/858 permits.<ref name="ecj-ruling">{{Cite web |url=https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=celex:62022CJ0296 |title=Case C-296/22 - CJEU Judgment |publisher=EUR-Lex |date=2023-10 |access-date=2026-04-04}}</ref> The court held that both read & write access to the OBD data stream must be granted to independent repairers & rejected the argument that UN Regulation 155 (vehicle cybersecurity) overrides EU access requirements.<ref name="ecj-analysis">{{Cite web |url=https://www.osborneclarke.com/news/ecj-decision-vehicle-manufacturers-may-not-restrict-access-vehicle-data-stream |title=ECJ decision: vehicle manufacturers may not restrict access to the vehicle data stream |publisher=Osborne Clarke |date=2023 |access-date=2026-04-04}}</ref> The court stated that if manufacturers could "limit at their discretion access to the direct vehicle data stream...it would be open to them to make access to that stream subject to conditions capable of making access impossible in practice."<ref name="ecj-analysis" />
