California has long been known for having some of the strongest legal protections in the country for consumers dealing with defective vehicles. With the introduction of Assembly Bill (AB) 1755 and Senate Bill (SB) 26, the state now operates under a dual-track lemon law system that affects how and when drivers can pursue a refund or replacement for a vehicle that cannot be repaired. These new procedures apply only to manufacturers who elect to participate, while others continue operating under traditional Song-Beverly Lemon Law rules. Because the correct path depends on manufacturer status and model year, many consumers may not even know which process applies until after repeated repair attempts. In some cases, drivers might unknowingly comply with the wrong procedural requirements, which could affect eligibility for civil penalties or delay resolution. The shift in procedure underscores how important it now is to understand where your vehicle falls before taking legal action.
Even with these changes, the heart of the law remains the same: if a warrantied defect substantially impairs your vehicle’s use, value, or safety, and the dealership cannot fix it, you may be entitled to a buyback or replacement. The difference now lies in how claims begin, how fast cases move, and what procedural steps must be followed. At Win Lemon Law, we guide California drivers through both processes to secure compensation as efficiently as possible. The updated laws were intended to streamline communication between consumers and automakers, but they have also added a layer of procedural complexity that requires strategic navigation. Understanding these rules early can lead to faster resolutions and better legal outcomes.
Two Legal Paths Now Exist for California Lemon Law Claims
Manufacturers who opt in to AB 1755 must apply the new procedural rules to all covered vehicles for a period of five years, and their status is published by the California Department of Consumer Affairs. Consumers must first determine whether their automaker is on this list and whether their specific vehicle falls within the covered scope, which is not always obvious from warranty language alone. Many drivers assume that repeated repairs automatically trigger traditional lemon law rights, when in reality the procedural obligations may differ based on manufacturer participation. This creates confusion for consumers who have never pursued a claim and may assume that the process is identical for all vehicle brands. Some drivers may even delay seeking help because they are unsure whether procedural requirements apply.
This distinction matters because each track dictates different deadlines, notice requirements, and litigation procedures. Two vehicles from the same manufacturer—built only a year apart—may fall into different legal processes, affecting how quickly compensation can be pursued. Win Lemon Law reviews repair history and manufacturer status early so no procedural steps are missed that could limit recovery. Taking action without understanding the correct track can result in lost rights or unnecessary delays. With the right legal strategy, however, consumers can benefit from whichever track provides the most leverage for their case.
How the Lemon Law Process Works When the Manufacturer Opts In

Under the opt-in procedure, consumers must send a written demand before filing suit if they intend to pursue civil penalties. This written notice must include key information such as defect details, repair documentation, the VIN, and a formal request for repurchase or replacement. Once the manufacturer receives the notice, it has strict timelines to respond and complete a buyback if it agrees, with financial penalties possible for non-compliance. This system is designed to encourage transparency and faster resolution, but it places the burden on consumers to prepare properly. When notices are incomplete or improperly formatted, manufacturers may claim that notice was not legally valid, which can impact available remedies.
If the manufacturer disputes the demand, mandatory mediation takes place before full litigation can proceed. During this stage, discovery is limited, which means consumers may have less access to internal manufacturer documents until mediation concludes. This can be challenging if the defect involves technical failures, software issues, or complex mechanical systems. Win Lemon Law prepares cases with complete documentation early so mediation is not a disadvantage and evidence is positioned effectively for escalation if needed. For some consumers, mediation may resolve the case quickly; for others, it may serve as a strategic starting point for litigation. Understanding how to present evidence at this stage can significantly influence the final outcome.
How Lemon Law Claims Proceed When the Manufacturer Does Not Opt In
If the manufacturer has not opted in—or the vehicle does not fall within covered model years—the case proceeds under traditional Song-Beverly procedures. Consumers may file a lawsuit without a pre-suit demand, and mediation is voluntary rather than mandatory. Discovery is broader, allowing attorneys to issue subpoenas, collect internal documents, depose manufacturer representatives, and request technical evidence necessary to prove the defect. This can be especially valuable in cases involving intermittent issues or software malfunctions. It also gives attorneys more tools to challenge manufacturer claims that a defect is normal or not reproducible.
While this pathway may take longer overall, it provides greater leverage in disputes where the manufacturer denies liability or insists the defect is “normal operation.” Some cases benefit from this structure because it allows full investigation into engineering defects or systemic issues affecting large numbers of vehicles. Win Lemon Law evaluates which approach provides the strongest strategy for each case rather than defaulting to one method for all clients. In certain situations, manufacturers may contest buyback eligibility aggressively, making full litigation the most effective route to secure compensation. Strategic case planning from the beginning can prevent procedural setbacks later.
Why Acting Quickly Matters More Than Ever
Because timelines vary depending on which legal track applies, delaying action can reduce available remedies. Under the opt-in track, deadlines may apply even shortly after warranty expiration, making prompt reporting especially important. Under the traditional track, the statute of limitations is generally longer, but evidence can weaken if repair attempts drag on without legal involvement. Many drivers continue returning to the dealership believing another repair attempt will solve the issue when they already qualify for a buyback. Others may hesitate to take action because dealership staff say the issue is “normal” or “working as designed,” even when symptoms persist.
Acting early also prevents manufacturers from arguing that a defect developed outside the warranty period or that repeated issues are unrelated. Repair documentation is one of the most critical pieces of evidence in a lemon law case, and waiting too long may result in missing invoices, lost service notes, or incomplete records. Win Lemon Law ensures documentation is preserved and legal deadlines are met from the outset. Many consumers are surprised to learn that earlier repairs may qualify them even if later visits are unsuccessful. A legal evaluation shortly after the first major repair attempt can save months of frustration.
How These Rules Impact Settlement Pressure on Manufacturers

The new dual-track system changes how manufacturers approach settlement negotiations. Under the opt-in process, the requirement to respond quickly to written demands and participate in early mediation may lead some automakers to resolve cases sooner to avoid penalties. However, others may rely on limited discovery to resist early buybacks, forcing consumers into extended disputes. These differences can change how much leverage a consumer has, especially if the defect is difficult to reproduce or diagnose. Having counsel who understands the strategic implications of each track can help determine which approach will create the greatest pressure.
In the traditional litigation track, broader access to evidence may increase pressure on manufacturers once a lawsuit is filed, but reaching that stage may take more time. This means strategy matters: some cases are better positioned for fast resolution under opt-in rules, while others benefit from full discovery rights. Win Lemon Law evaluates each case to determine which track creates the greatest pressure for a favorable outcome. Some consumers may prioritize speed over maximum compensation, while others want to pursue civil penalties to hold manufacturers accountable. Each case is unique, and the legal path should reflect the client’s goals.
Why Legal Representation Matters Under the New System
With two legal pathways now in place, navigating a lemon law claim without legal guidance has become more complex. Consumers may assume filing a claim is as simple as returning to the dealership or calling the manufacturer’s helpline, but procedural missteps—such as sending incorrect notice or missing model-year restrictions—can weaken or delay a case. Even small errors in documentation can impact eligibility for civil penalties, reimbursement amounts, or replacement timelines. Manufacturers often use process-based defenses rather than addressing the defect head-on.
Legal representation ensures compliance with filing rules, correct presentation of repair history, and proper communication with the manufacturer. It also creates a record that can be used in litigation if the manufacturer attempts to minimize or deny the defect. Win Lemon Law handles the entire process from first repair review to settlement or court action so drivers do not have to negotiate with automakers directly. Our experience allows us to anticipate common defense strategies and prepare evidence preemptively. Working with counsel early often leads to faster and more favorable resolutions.
