The Tanner Act sets 4 attempts (2 for safety) or 30 days out of service as the legal threshold, but courts can find fewer sufficient depending on defect severity.
California lemon law does not require an exact number of repair attempts in every case — it requires a “reasonable” number. While the Tanner Act creates a presumption after four attempts (or two for safety defects, or 30 days out of service), the underlying legal standard is reasonableness. Here is what that means in practice.
The core obligation under Cal. Civ. Code § 1793.2(d) is that the manufacturer must repurchase or replace a vehicle when it “is unable to service or repair a new motor vehicle… to conform to the applicable express warranties after a reasonable number of attempts.” The statute does not define a specific number — it requires what is reasonable given the circumstances.
The Tanner Act’s numerical thresholds (four attempts, two for safety, 30 days) create presumptions of unreasonableness but are not the only path to a claim. Courts and juries can find that fewer attempts were unreasonable if the defect was severe, if each attempt made the problem worse, or if it was obvious the manufacturer’s repair approach was not working.
When evaluating whether a reasonable number of attempts has been made, California courts look at:
The cleanest lemon law cases are ones where the Tanner thresholds are clearly met. If you have four repair orders showing the same defect code, the same symptom description, and the car still has the problem, the manufacturer bears the burden at trial of showing the vehicle is not a lemon. In practice, most cases settle long before trial once these thresholds are documented.
For safety defects, the two-attempt presumption is frequently triggered on first consultation with an attorney. If your brakes have been repaired twice for the same issue and are still not working properly, or your car has stalled twice at highway speed without the dealer finding a fix, you very likely have a claim right now.
The four-attempt presumption requires four attempts to fix the same defect. Courts apply a practical, consumer-oriented interpretation of “same defect” — they look at the underlying problem, not the specific diagnostic codes or repair descriptions. If your car lurches and hesitates during acceleration and the dealer has replaced the fuel pump, cleaned the fuel injectors, reprogrammed the ECU, and replaced the throttle body on four separate visits without fixing the problem, those are four attempts on the same defect (drivetrain hesitation) even though each repair was technically different.
Document the symptom from your perspective consistently. Write it down the same way every time you drop the car off: “Vehicle hesitates and lurches during acceleration, especially when cold. Has occurred every week since purchase.” Consistent consumer-facing descriptions create a clear record that the same defect persisted through multiple attempts.
An experienced lemon law attorney may be able to build a case with three (or even fewer) repair attempts if:
Under California’s Lemon Law, a vehicle is presumed to be a “lemon” if the manufacturer cannot conform it to warranty after a reasonable number of repair attempts. The law does not prescribe an exact number; instead, it establishes a framework that depends on the nature of the defect and the time the vehicle has been out of service. California Civil Code § 1793.22(a)(2) provides the primary test: a defect is incurable if the manufacturer has had a reasonable opportunity to repair it and has failed to do so. Courts and administrative bodies interpreting this statute have consistently held that “reasonable” depends on the circumstances, considering both the severity of the defect and the manufacturer’s efforts to fix it.
The legislature recognized that some defects are more serious than others and established different thresholds accordingly. For defects that relate to safety, fewer repair attempts are needed to establish the presumption. For other defects, more attempts may be required. The law also takes into account the cumulative time the vehicle has been unavailable for use, recognizing that consumers need reliable transportation and should not have to keep taking their cars back to the dealer indefinitely. This multi-factor approach gives the law flexibility while still protecting consumers from manufacturer negligence or inability to fix problems.
California Civil Code § 1793.22(b)(1) establishes a critical presumption: if a defect in the vehicle that affects its safety has not been repaired after two or more repair attempts by the manufacturer or its agents, the vehicle is presumed to be a lemon. This rule recognizes that safety-related defects are fundamentally different from cosmetic or comfort issues. Safety defects include problems with brakes, steering, airbags, seatbelts, suspension, lighting, and any other system that directly impacts the vehicle’s ability to operate safely or protect occupants. Because safety defects pose an immediate risk to the driver and passengers, the law does not require multiple repair attempts before granting relief.
If you have documented at least two separate repair attempts for a safety-related defect that has not been fixed, you have a strong presumption under the Lemon Law. The manufacturer bears the burden of proving that the vehicle actually does not have a safety defect, or that the defect was not caused by the manufacturer, or that the repairs were unsuccessful due to your own actions. This presumption is rebuttable, meaning the manufacturer can try to prove otherwise, but it places the burden on them. You do not need to prove that the manufacturer was negligent or willful in their failure to repair; you only need to show two repair attempts by the manufacturer or dealership for the same safety defect.
For defects that do not affect safety, California Civil Code § 1793.22(b)(2) establishes a higher threshold. A vehicle is presumed to be a lemon if a non-safety defect has not been repaired after four or more repair attempts by the manufacturer or its agents. Non-safety defects include problems with the transmission, engine performance, electrical systems (outside of safety lighting), air conditioning, stereo systems, seat adjustments, and interior trim. Because these defects do not pose an immediate safety risk, the law allows the manufacturer more attempts to fix them. However, four repair attempts for the same problem is still a reasonable number, and most consumers would expect their vehicle to be fixed within four visits to the dealership.
The four-attempt threshold applies to each distinct defect. If your vehicle has multiple problems—for example, a transmission issue and a paint defect—you count repair attempts separately for each problem. If the transmission has been repaired four times without success, you have a presumption of lemon status, even if the paint defect has only been addressed once. Similarly, if the dealership attempts to repair multiple unrelated issues during a single visit, each repair attempt counts toward the total, but only for the specific defect being addressed. Documenting which defect was addressed during each visit is essential for establishing that you have met the four-repair-attempt threshold.
California Civil Code § 1793.22(b)(3) provides an alternative pathway to establishing lemon status: if the vehicle has been out of service for repair for a cumulative total of more than 30 days during the warranty period, it is presumed to be a lemon. This rule recognizes that repeated repairs, even if fewer than two or four attempts, constitute an unreasonable burden on the consumer. The 30-day rule is separate from and independent of the repair-attempt thresholds. You do not need to prove two or four repair attempts if you can show that your vehicle spent more than 30 days in the shop during the warranty period. Conversely, you do not need to reach the 30-day threshold if you have already established lemon status through the repair-attempt rules.
The 30 days are calculated cumulatively, meaning all the time your vehicle spent in the shop is added together. If you dropped your car off for a week, then brought it back a month later for another repair that lasted five days, those 12 days combined count toward the 30-day threshold. The calendar days do not need to be consecutive. However, time spent waiting for an appointment, time spent driving to and from the dealership, and time the vehicle spends at your home after being returned from repair do not count. Only the time when the dealership actually has possession of the vehicle for repair purposes is counted. Once you cross the 30-day threshold, you have a presumption of lemon status, and the burden shifts to the manufacturer to prove that the vehicle is not a lemon.
A presumption under § 1793.22 is a powerful legal tool that shifts the burden of proof. Once you establish that your vehicle meets one of the statutory criteria—two repair attempts for a safety defect, four repair attempts for another defect, or 30+ cumulative days out of service—the law presumes your vehicle is a lemon. This does not mean the manufacturer has automatically lost your case; it means that the manufacturer must now prove that your vehicle is not defective, or that the defect cannot be attributed to a manufacturing defect, or that the defect does not substantially impair the use or value of the vehicle. The presumption is rebuttable, but it is a strong one. In practice, meeting the statutory criteria often leads to a favorable settlement or judgment for the consumer, because the manufacturer’s burden is difficult to overcome.
The importance of this presumption cannot be overstated. Without it, you would have to prove that the manufacturer knew the vehicle was defective and either willfully refused to repair it or was negligent in failing to repair it. With the presumption, you only need to prove the factual elements: that repair attempts occurred, that they were unsuccessful, and that the defects existed within the warranty period. The manufacturer’s intent is irrelevant. Even if the dealership was trying its best to fix the problem, if they failed after two or four attempts, or if the vehicle spent more than 30 days in the shop, the presumption applies. This shifts the case from a difficult negligence claim into a statutory claim that the law explicitly contemplates.
Yes. Under California Civil Code § 1793.22(e), the manufacturer has the right to attempt one final repair of the defect before the consumer can enforce their right to a refund or replacement. This final repair attempt must occur within 30 days of notice from the consumer or their attorney that the vehicle qualifies as a lemon. This provision gives the manufacturer a last opportunity to cure the defect and avoid buyback or replacement. However, this final repair right is not unlimited. The manufacturer must complete the repair within the 30-day window, and if the repair is unsuccessful—meaning the same defect persists—the consumer’s right to a refund or replacement is not delayed or diminished.
In practice, the final repair right can be a double-edged sword. Some manufacturers use this opportunity to genuinely fix the problem, and the vehicle is successfully repaired, ending the case. In other situations, the manufacturer makes a superficial repair attempt that fails, further confirming that the vehicle is not repairable. If the manufacturer fails to complete the repair within 30 days, or if the repair is unsuccessful, the consumer can proceed immediately to seek buyback or replacement. You do not need to attempt additional repairs or give the manufacturer additional opportunities. The final repair right exists to give the manufacturer one last fair chance, but it does not extend the timeline or create new obligations for the consumer once the statutory criteria for lemon status have been met.
Counting repair attempts requires careful attention to what constitutes a separate “attempt.” Each time you take your vehicle to an authorized service facility for repair of a defect, that is one repair attempt. If you take the vehicle in on Monday and it is not fixed, and you return it on Friday for another attempt at the same repair, that counts as two separate attempts. If the dealership keeps your vehicle for two weeks and works on the defect continuously during that time without fixing it, that still counts as one repair attempt, not multiple attempts just because work occurred on multiple days. The key is that each visit or service order for repair of a defect counts as one attempt, regardless of how long the repairs take or how much work is done.
Multiple defects addressed during one visit count as multiple repair attempts if they involve different problems. For example, if the dealership works on your transmission and your air conditioning during the same visit, that counts as one repair attempt for the transmission and one repair attempt for the air conditioning. Diagnostic visits where the dealership attempts to identify a problem count as repair attempts if they result in work being done. However, if the dealership simply diagnoses the problem without actually attempting to repair it, the classification of that visit as a “repair attempt” is more complicated and depends on whether work was performed. Keeping detailed service records showing the date of each visit, the defect addressed, and the description of work performed is essential for accurately counting your repair attempts.
