Start with the records. Repair orders, warranty documents, mileage, and days out of service are more useful than general assumptions about whether a vehicle qualifies.
Modern vehicles rely on forward-facing cameras to power ADAS features like lane-keeping, adaptive cruise control, and automatic emergency braking. When those cameras are misaligned or poorly calibrated, drivers can experience false alerts, phantom braking, or features that randomly drop out—undermining confidence and safety. If these problems continue despite warranty repairs, some California owners wonder whether the state’s Lemon Law might apply.
California Lemon Law: Poorly Calibrated Cameras
Advanced driver-assistance systems (ADAS) depend on precise camera calibration. Common signs of a calibration problem include steering assist that wanders or “ping-pongs” between lane lines, repeated “camera blocked” or “calibration required” messages, emergency braking triggers with no obstacle present, or ADAS functions that disable themselves after a few minutes. These issues can surface after a windshield replacement, collision repair, suspension work, or even a software update. Because ADAS features interact with braking and steering, persistent camera errors can affect the vehicle’s safety, use, and value.
California’s Lemon Law (part of the Song-Beverly Consumer Warranty Act) generally protects buyers and lessees of new vehicles—and in some cases certain used vehicles still under the manufacturer’s warranty—when a substantial defect cannot be fixed after a reasonable number of repair attempts. A “substantial” defect is one that significantly affects use, value, or safety. The law includes a guideline often called the “Lemon Law Presumption”: during the first 18 months or 18,000 miles, a vehicle may be presumed a lemon if the manufacturer or dealer has made four or more attempts to repair the same problem, two or more attempts for a defect likely to cause serious injury or death, or the vehicle has been out of service for a total of 30 or more days for warranty repairs. These are guidelines, not guarantees, and cases can qualify even without meeting the presumption.
Poorly calibrated cameras can fit into this framework when the defect repeatedly returns despite warranty repairs. For example, if the dealer recalibrates the forward camera after a windshield replacement but the ADAS keeps faulting, or if multiple software flashes and alignment checks fail to resolve phantom braking, the pattern may support a Lemon Law claim. Outcomes depend on the facts: the number of repair attempts, how the defect impacts safety and drivability, and the documentation showing the manufacturer had a fair chance to fix it. This article is informational only; a consultation is needed to evaluate any specific situation.
Documenting ADAS Camera Defects and Repairs
Thorough documentation is one of the most practical steps you can take. Each time the issue occurs, note the date, mileage, speed, weather, road markings, and what message appeared on the dash. If safe to do so, take photos or short videos of warning lights or messages. When you visit the dealer, describe the symptoms in clear, consistent terms—“phantom braking on a clear highway,” “lane-keep assist bounces between lines,” or “camera calibration resets after every start”—and ask that your exact wording be included on the repair order.
Keep every repair invoice, even if the dealer writes “could not duplicate” or “no trouble found.” Those entries still show that you presented the vehicle for repair. Ask for copies of any calibration reports, alignment sheets, software update versions, and TSB (Technical Service Bulletin) numbers referenced by the technician. If the windshield was replaced, keep that invoice and confirm the brand of glass and whether OEM calibration procedures were followed.
A few general tips can help you move things forward: schedule repairs promptly when the issue appears; avoid clearing codes yourself so the dealer can pull fault data; test the vehicle soon after each repair and return quickly if the problem persists; and check whether your warranty, certified pre-owned coverage, or a recall applies. If the vehicle spends extended time in the shop, track the days out of service. If you’re unsure how these details fit your situation, consider contacting a professional for a consultation to discuss your options.
