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.
Headlight alignment problems can turn an otherwise good car into a nightly safety concern. If your headlights keep pointing too high, too low, or off to the side, you may struggle to see the road—or worse, you might blind oncoming drivers. For many California drivers, repeated trips to the dealership for alignment that doesn’t hold raises a common question: does this qualify as a lemon?
At ZapLemon, we hear from consumers who’ve tried everything—re-aiming, replacing bulbs, even swapping headlamp assemblies—only to have the headlights drift out of alignment again. Modern systems can add complexity: adaptive or auto-leveling headlights rely on sensors, motors, and control modules that must work together. When those parts don’t cooperate, the problem can be persistent, frustrating, and unsafe.
Below, we explain how California’s Lemon Law can apply to misaligned headlights and how to document your repair history. This article is for general information only. It isn’t legal advice, and reading it doesn’t create an attorney-client relationship. If you want guidance on your situation, please contact ZapLemon for a consultation.
Do Misaligned Headlights Qualify as a Lemon in California?
California’s Lemon Law (the Song-Beverly Consumer Warranty Act) can cover headlight alignment issues when they substantially impair the vehicle’s use, value, or safety and the manufacturer or its authorized dealer can’t fix them after a reasonable number of attempts during the warranty period. Headlight misalignment often goes straight to safety—if you can’t see the road at night, or your lights glare into oncoming traffic, that’s not just an annoyance. The key questions are: is the vehicle under the manufacturer’s warranty, is the defect recurring, and does it meaningfully affect use, value, or safety?
The law includes a “presumption” that can make claims easier to prove if certain benchmarks are met within the first 18 months or 18,000 miles (whichever comes first): 4 or more repair attempts for the same problem; 2 or more attempts for a defect that could cause death or serious injury; or 30+ total days out of service for warranty repairs. These are guidelines, not hard limits. A vehicle can still qualify outside those windows or without meeting the presumption, depending on the facts.
Not every headlight concern will qualify. For example, damage from accidents, aftermarket modifications (such as lift kits or non-OEM headlamp housings), or normal wear can complicate a claim. On the other hand, recurring misalignment, failed auto-leveling sensors, moisture causing internal movement, or adaptive lighting modules that won’t calibrate may point to a warrantable defect. If the dealer keeps “re-aiming” the lights but the problem returns, or if you’re getting “no problem found” despite clear nighttime visibility issues, it may be time to explore your options.
Document Repairs for California Lemon Law Claims
Documentation is your best friend. Each time you visit the dealer, ask for a detailed repair order that lists your specific complaint (for example: “right headlight points too high and blinds oncoming traffic,” “beam pattern drifts after bumps,” “auto-leveling fails on startup”). Make sure the mileage, dates, and days out of service are correct, and keep copies of every invoice—even if the dealer says “could not duplicate.” Photos or short videos showing the beam pattern against a garage wall, a fence line, or roadway signs at night can help illustrate what you’re experiencing.
Be consistent in how you describe the symptoms, and note when they occur: after hitting bumps, when the car is loaded with passengers, in rain, or after engine start when the auto-leveling sweep runs. If the dealer performs calibration or replaces parts (such as a headlamp control module, leveling sensor, or headlight assembly), ask them to list the part numbers and any technical service bulletins (TSBs) referenced. If the issue returns, schedule follow-up visits promptly and repeat the same concern to build a clear record of repeat attempts.
Beyond dealer visits, open a case with the manufacturer’s customer care line and save emails, case numbers, and call logs. If the vehicle spends many days in the shop, total them up. Avoid modifications that can muddy the waters—installing aftermarket bulbs or suspension changes while a claim is ongoing can give the manufacturer a defense. If repairs stall or you’re not getting clarity, consider exploring manufacturer arbitration programs or speaking with a lemon law attorney to discuss timelines and options.
Persistent headlight alignment problems can be more than a nuisance—they can be a safety risk and, in some cases, a lemon law issue. The strongest claims usually pair a safety-impacting defect with clear, repeated repair attempts and thorough documentation. Understanding your warranty, tracking repairs, and knowing when to escalate can help you move forward.
