Recurring lane departure system issues on a Ford? California's Lemon Law may entitle you to a full refund or replacement — at no cost to you.
Get a Free Case ReviewIf your Ford is experiencing lane departure system problems that your dealer has been unable to permanently fix, you may be entitled to a full repurchase, replacement vehicle, or cash settlement under California's Song-Beverly Consumer Warranty Act — widely regarded as the strongest lemon law in the United States.
Ford owners across California have successfully recovered the full purchase price of their vehicles after repeated failed repair attempts for lane departure system defects. California law requires Ford to either repair the defect in a reasonable number of attempts or buy the vehicle back — and if the company refuses, it may owe you up to twice the purchase price as a civil penalty.
This page covers everything you need to know: what Ford lane departure system defects qualify, how the lemon law process works, what compensation you can recover, and answers to the questions our clients ask most often. If you've already made multiple dealer visits for the same problem, you may already qualify — read on to find out.
Lane departure warning and lane keeping assist systems that malfunction — either failing to warn of genuine lane departures or actively steering the vehicle incorrectly — are safety-critical defects under California law, requiring as few as two failed repair attempts to establish a lemon law claim.
Under California's lemon law presumption, your Ford is presumed to be a lemon if, within 18 months or 18,000 miles from original delivery (whichever comes first), any of the following apply:
You do not need to satisfy all three criteria — any one of them is sufficient to trigger the presumption. And even if you fall short of these thresholds, you may still have a valid claim if the defect is serious enough or the manufacturer's response was unreasonable.
Ford models that have generated lane departure system complaints in California include the F-150, Explorer, Escape, Mustang, and Edge. If you own one of these models and have returned to the dealer repeatedly for the same issue, your case deserves a professional evaluation.
Lane Departure System defects in Ford vehicles manifest in a variety of ways. The following are the most frequently reported issues by Ford owners who have pursued — and won — lemon law claims in California. If your vehicle shows any of these symptoms after multiple repair attempts, you likely have a strong claim.
A system that constantly warns of lane departures when the vehicle is centered in its lane trains drivers to ignore alerts — creating a safety hazard when a real departure occurs. Repeated dealer visits that cannot resolve false alerts establish a strong repair history.
Lane departure systems that fail to trigger when the vehicle genuinely drifts across lane markings are failing their core safety function. This is among the most serious ADAS defects because it provides false security without actual protection.
Lane keeping assist that actively steers the vehicle into adjacent lanes or toward the shoulder — rather than correcting the drift — can cause collisions. Even a single documented occurrence of dangerous steering intervention may support a claim.
Lane departure and lane keeping systems that disengage without warning at highway speeds — leaving the driver without expected assistance — substantially impair the vehicle's marketed safety capabilities.
The camera systems that power lane departure detection degrade or become contaminated, causing unreliable performance. Dealer cleaning or recalibration that provides only temporary relief establishes a repair history.
Lane departure systems that routinely fail in rain, glare, or faded lane marking conditions — beyond what the manufacturer's documentation discloses — may be defective if the conditions are commonplace in California driving.
Manufacturer-pushed software updates intended to address lane departure system faults that fail to resolve the issue — or introduce new problems — count as failed repair attempts under California law.
When a Ford owner reports a lane departure system problem, dealers typically begin with the least invasive steps — diagnostic scans, software updates, fluid changes, or component cleaning — before escalating to part replacement or system overhaul. This incremental approach is common across the industry, but it often means the root cause goes unaddressed over multiple visits while the repair order count climbs.
Lane departure defects are often addressed through software updates and camera recalibration. Document every update and its effect. If the issue returns after a software fix, that is a failed repair attempt. Dashcam footage of the malfunction is highly persuasive evidence.
A critical point many Ford owners miss: every service visit counts as a repair attempt — including visits where the dealer documents "no fault found" or "unable to duplicate concern." Those visits still establish that you reported the problem and the manufacturer failed to resolve it. If you have three or four repair orders for the same complaint, your case may already meet the legal threshold.
Organize every repair order chronologically. Note the date, mileage, and the exact complaint you described each time. This paper trail is the backbone of your lemon law case and the first thing an attorney will review.
California's Song-Beverly Consumer Warranty Act applies to new and certain used vehicles purchased or leased in California that come with a manufacturer's express warranty. It requires manufacturers — including Ford — to repair defects that impair the vehicle's use, value, or safety. When those defects cannot be permanently repaired in a reasonable number of attempts, the manufacturer must either replace the vehicle or buy it back.
California's lemon law is significantly stronger than the federal Magnuson-Moss Warranty Act in several important respects:
The law applies to vehicles purchased for personal, family, or household use — including daily commuters. Commercial fleet vehicles are subject to different standards, but single business-use vehicles may still qualify. An attorney can evaluate your specific situation quickly and at no cost to you.
A successful lemon law claim against Ford can result in substantial financial recovery. California law provides three primary remedies:
Ford repurchases the vehicle and refunds: your down payment, all monthly payments made, registration and licensing fees, taxes, and incidental expenses (rental cars, towing, repair-related costs) — minus a mileage offset calculated from delivery date to first reported defect.
Ford provides a comparable new vehicle — same make, model, and trim level — at no net cost beyond the same mileage offset. Replacement vehicles come with a fresh warranty.
Many lemon law cases resolve with Ford paying a negotiated lump sum while you keep the vehicle. For owners who have grown accustomed to their car or cannot wait for a buyback process, this option often delivers immediate value.
Civil Penalty: If a court finds that Ford willfully refused to comply with its buyback obligation, California law allows the court to award up to two times the vehicle's purchase price as an additional civil penalty — on top of the buyback amount.
Attorney Fees: Under Song-Beverly, Ford must pay your reasonable attorney's fees and litigation costs if you prevail. This is what makes the California lemon law work for consumers: you pay nothing to pursue your claim.
If your Ford has a lane departure system defect, the actions you take in the next few days can significantly affect the outcome of your claim. Here is what to do:
Time matters. California's lemon law has a 4-year statute of limitations from when you knew or should have known of the defect — but acting sooner means better documentation, fresher memories, and faster resolution.
Yes. Lane departure warning and lane keeping assist are marketed as safety systems. When they malfunction — either failing to warn or actively causing dangerous steering — they meet the definition of a safety-critical defect, which requires only two failed repair attempts under California law.
Document the incident immediately with a written description (date, time, road, speed, conditions), then take the vehicle to the dealer the same day. If you have a dashcam, preserve the footage. This type of incident can support both a lemon law and a product liability claim.
Yes. Disabling a safety feature because it is dangerous is itself evidence of a defect. Many lemon law attorneys have successfully argued that a vehicle is substantially impaired when its owner is forced to turn off a core safety system.
Sometimes, but frequently they provide only temporary improvement. If your system malfunctions again after an update, that update was a failed repair attempt. Keep records of every update notification and whether it changed the problem.
Intermittent defects are common in ADAS systems. Keep a detailed log of every occurrence — date, time, speed, road conditions, weather — and capture dashcam or phone video when it happens. Intermittent defects are legally valid under California law.
California law does not require the dealer to reproduce the defect. Your documented log of incidents, combined with the repair orders showing you reported the problem, is sufficient to establish the defect exists.
