If your brand‑new car’s Lane Keep Assist won’t turn on from day one—maybe the icon stays gray, you see “Unavailable” messages, or the steering nudge never arrives—you’re not alone. Advanced driver-assistance features (ADAS) like Lane Keep Assist should work under normal conditions when the vehicle is new and under warranty. Below we explain how factory Lane Keep Assist problems show up, what California’s Lemon Law generally requires, and practical steps you can take to protect your rights. This article is for informational purposes only and is not legal advice.
Lane Keep Assist Not Engaging From the Factory?
Lane Keep Assist (sometimes called LKA or Lane Keeping) is designed to gently steer or provide corrective input to help keep your car centered in its lane. When it doesn’t engage from the factory, common signs include a grayed-out dashboard icon, repeated “feature unavailable” messages, or the system dropping out even on clear, well-marked highways. It’s different from Lane Departure Warning, which only beeps or vibrates. If LKA never comes on under proper conditions, that can point to a manufacturing or setup issue rather than normal behavior.
Because LKA activates only when certain conditions are met—like visible lane lines, adequate speed, and your hands on the wheel—it’s smart to rule out simple causes. Try different roads in good lighting and weather, remove windshield-mounted accessories that block the camera, and confirm the feature settings in your owner’s manual. If the system still won’t engage, the cause could be factory-related: a miscalibrated forward camera, improper alignment, a steering torque sensor issue, unprogrammed control module, CAN communication fault, or software that needs an update right from the start.
Document the problem early. Take clear notes on when and where LKA fails, record short videos if it’s safe to do so, and schedule a warranty visit promptly. Ask the dealer to document your concern on the repair order—even if they say “could not duplicate”—and request copies of every repair invoice. Inquire whether there are technical service bulletins (TSBs), recalls, or over‑the‑air/software updates, and whether calibration certificates (for the camera/radar) were completed. Good records help the dealer troubleshoot and help you later if your vehicle’s issues persist.
CA Lemon Law and Factory Lane Keep Assist Issues
California’s Lemon Law (the Song‑Beverly Consumer Warranty Act) generally helps consumers when a new or certified pre‑owned vehicle has a defect covered by warranty that the manufacturer can’t fix after a reasonable number of attempts. The defect must substantially impair the vehicle’s use, value, or safety. An LKA system that won’t engage from the factory can be more than an annoyance—if it undermines driver confidence or relates to safety, it can factor into whether the problem is “substantial” under the law.
What counts as a “reasonable” number of repair attempts depends on the facts. Broadly speaking, multiple unsuccessful repairs or the car being out of service for 30 or more cumulative days can support a Lemon Law claim. Safety‑related issues may require fewer attempts, but there’s no one‑size‑fits‑all rule. Possible outcomes under the law can include repurchase (buyback), replacement, or a negotiated cash‑and‑keep settlement, often with a mileage offset; however, results vary and are never guaranteed.
Practical steps: keep every repair order and calibration printout, ask the dealer to note specific symptoms (“LKA icon remains gray; no steering assist”) rather than generic entries, and request a complete warranty repair history printout. Avoid aftermarket windshield tints or accessories that can complicate camera operation while the issue is being diagnosed, and keep your software up to date through the dealer. If the dealer says “normal,” politely ask for a test drive and compare to another identical model when possible. For guidance tailored to your situation, a consultation with a California lemon law attorney can help you understand your options.
