01 · Core standard
Reasonableness—not a universal magic number
Civil Code section 1793.2(d)(2) addresses a manufacturer or representative unable to conform a qualifying new motor vehicle to its applicable express warranties after a reasonable number of attempts. The nonconformity must substantially impair use, value, or safety to the buyer or lessee. The statute does not say that every California vehicle becomes a lemon after four visits, or that any repeated concern automatically qualifies.
Reasonableness remains fact-dependent except where an applicable statutory presumption assists the consumer. Relevant records show what condition was presented, whether the presentation concerned the same recurring problem, what opportunity was provided, what response occurred, and what happened afterward. A repair tally detached from the condition, timing, warranty, and impact can obscure rather than answer the statutory question.
02 · Plural attempts
Silvio: one opportunity is insufficient for this duty
Silvio v. Ford Motor Co. explains that one opportunity is insufficient for the section 1793.2(d)(2) refund-or-replacement obligation because the statute uses “attempts” in the plural. That is a defined lower boundary for this obligation. It should not be restated as a broad rule that the second repair automatically completes every other required element.
Two opportunities are merely the minimum necessary to satisfy the plural concept discussed in Silvio. Whether the number was reasonable still depends on the facts unless the Tanner presumption applies. Warranty coverage, the nature and recurrence of the nonconformity, the opportunities actually provided, substantial impairment, and the complete history remain part of the analysis.
03 · Tanner window
The presumption uses 18 months or 18,000 miles
Civil Code section 1793.22 creates a rebuttable presumption concerning a reasonable number of attempts when specified conditions occur within 18 months from delivery or 18,000 miles on the odometer, whichever comes first. It is a presumption, not the underlying reasonable-number standard and not an automatic remedy.
Failure to satisfy Tanner does not automatically mean a consumer lacks a claim. Meeting a listed numerical condition does not justify telling a consumer that restitution is guaranteed. The timing window and every statutory condition must be reviewed. Evidence outside the window may remain part of the broader repair history, but this guide does not announce a new rule about its effect.
Tanner window: 18 months from delivery OR 18,000 odometer miles, whichever occurs first.
04 · Three categories
Keep the Tanner thresholds exact
For a same nonconformity resulting in a condition likely to cause death or serious bodily injury if driven, the category is two or more repair presentations by the manufacturer or its agents, subject to statutory conditions. For another same nonconformity, the category is four or more repairs, again subject to the statute. Manufacturer-direct-notice requirements must be described conditionally where the disclosure requirement in section 1793.22 is satisfied.
A separate category applies where the vehicle is out of service by reason of repair of nonconformities by the manufacturer or its agents for a cumulative total of more than 30 calendar days since delivery within the applicable window. The statute provides an extension where repairs cannot be performed due to conditions beyond the control of the manufacturer or agents.
- Serious-safety same nonconformity: 2 or more, subject to conditions
- Other same nonconformity: 4 or more, subject to conditions
- Downtime: more than 30 cumulative calendar days, subject to conditions
Contextual review
The legal category organizes the question. The authentic warranty, transaction, and repair record answers it.
05 · Notice condition
Manufacturer-direct notice is conditional, not boilerplate
Tanner contains manufacturer-direct-notice provisions tied to statutory disclosure conditions. A public guide should not tell every consumer that direct notice is always required, or omit it where the conditions apply. Preserve the warranty materials and disclosures delivered with the vehicle, along with any direct manufacturer correspondence, so the condition can be evaluated accurately.
This Tanner notice issue is distinct from the opt-in pre-suit civil-penalty notice under Code of Civil Procedure section 871.24. Similar words do not make the procedures interchangeable. One concerns use of Tanner’s rebuttable presumption under its conditions; the other concerns an action subject to section 871.20 seeking Civil Code section 1794(c) civil penalties.
06 · Arbitration overlay
Qualified dispute resolution can affect the presumption
If a qualified third-party dispute-resolution process exists and the statutory notice conditions apply, section 1793.22 contains an initial-resort requirement before the Tanner presumption may be asserted. That arbitration overlay is not the same as the manufacturer opt-in procedure in Code of Civil Procedure sections 871.20–871.30.
This page does not provide a comprehensive arbitration guide. Keep any program notice, application, submission, response, decision, and timing record. An attorney can assess whether the process is qualified and what effect the statutory conditions have. Do not infer that arbitration is universally required for every California lemon-law action.
07 · Same and different concerns
Do not manufacture an aggregation rule
Tanner’s two- and four-presentation categories use the same-nonconformity concept. A chronology should therefore identify which owner-observed condition recurred and how each repair order describes it. Changing technical diagnoses do not necessarily answer whether the owner reported the same condition, but the consumer should not merge unrelated events merely to create a larger number.
The approved authorities do not support a universal public rule here about aggregating unrelated defects. Keep complaint lines separate, preserve the dealer’s actual classifications, and let counsel evaluate the record under the applicable standard. Different concerns may be relevant to the overall file, but this guide does not declare how they must be combined.
08 · Build the record
Turn the repair-attempt history into a dated chronology
A useful chronology begins with the delivery documents and follows every service event in order. For each event, retain the appointment request, drop-off and release dates, mileage in and out, the complaint as actually reported, the facility’s findings, work performed, and the first known recurrence. Keep the final repair order rather than only an estimate or text-message summary. Where dates or wording conflict, preserve both records and identify the discrepancy instead of silently correcting it.
Keep manufacturer case numbers, emails, text threads, towing records, loaner or rental documents, photographs, videos, and parts-delay communications with the corresponding visit. Original files and complete threads are more useful than edited montages or recollections created later. A chronology should distinguish what the consumer observed from what a technician diagnosed. It should also include visits that ended without a repair, while leaving the legal significance of each event for an individualized review.
09 · Accuracy first
Document facts without improving the story
Before signing a repair order, read the complaint line and ask that factual omissions or errors be corrected. State the exact warning, behavior, frequency, operating circumstances, and practical effect. Do not supply a technical diagnosis unless a qualified source made it, and do not adopt stronger wording merely because it sounds legally important. An accurate description that can be compared across visits is more useful than an exaggerated label that the underlying evidence does not support.
At pickup, compare the complaint, cause, correction, dates, and mileage. Preserve any original evidence given to the service adviser and the message showing when it was sent. Do not alter an issued invoice; retain a separate note of questions. If the condition returns, record the date, mileage, circumstances, and whether the reported behavior is genuinely the same. This discipline helps counsel evaluate the complete history without treating a consumer allegation, dealer notation, or repair choice as conclusive by itself.
10 · Individual review
Keep eligibility, procedure, and remedy separate
The core refund-or-replace framework concerns a qualifying new motor vehicle that the manufacturer or its representative could not conform to the applicable express warranties after a reasonable number of attempts, where the nonconformity substantially impairs use, value, or safety to the buyer or lessee. The buyer may elect restitution instead of replacement. No single repair notation, number, expense, or delay should be presented as an automatic buyback.
Procedure can also depend on whether the manufacturer elected into Code of Civil Procedure sections 871.20–871.30 for the relevant vehicle-sale year. That election is not universal or permanent. Current election information should be checked through the California Department of Consumer Affairs for the particular manufacturer and year. State-certified manufacturer arbitration is a separate overlay and should not be conflated with the opt-in procedure. These guides provide general information, not a deadline or outcome for one file.
11 · Review sequence
Ask the questions in a disciplined order
First identify the vehicle, acquisition, delivery date, sale year, written warranty, and the manufacturer-authorized facilities involved. Next identify the precise nonconformity or transaction item addressed by the guide. Then place each presentation, response, unavailable period, notice, and recurrence in chronological order. Only after those facts are organized should the reviewer select the traditional Song-Beverly framework or determine whether a manufacturer election makes Code of Civil Procedure sections 871.20–871.30 applicable to the action.
That order prevents a conclusion from driving the evidence. A consumer should not choose a mileage because it produces a preferred offset, merge complaints because it produces a preferred visit count, or assign days to a legal category before identifying which rule is being considered. The same discipline applies to favorable and unfavorable documents. Include repairs that appeared successful, periods of ordinary operation, manufacturer responses, and records that do not use the consumer’s preferred language. Completeness allows the approved rules to be applied rather than presumed.
12 · Source boundaries
Know what each document can and cannot establish
A purchase or lease agreement establishes transaction terms; a warranty booklet supplies written coverage language; a repair order records a presentation and facility response; original media may capture an event; and manufacturer correspondence records what was communicated. None necessarily proves every other point. A repair order naming a replaced part does not by itself establish substantial impairment. A photograph of a warning does not establish its cause. A payment schedule does not establish which amount is recoverable. Keep each source in its proper evidentiary lane.
Public statutes and approved cases supply the legal framework, while the California Department of Consumer Affairs supplies current manufacturer-election information. Neither replaces VIN-specific documents or an attorney’s application of law to facts. Do not rely on anecdotes, model reputation, a dealership’s legal opinion, or an online calculator as the final answer. These pages intentionally stop where the approved propositions stop: they organize the issue, identify the controlling distinctions, and show which authentic records are needed for a prompt individualized review.
