Pursuing a Lemon Law or Warranty Claim: A Practical Checklist

15 U.S.C. § 1691

Type: Checklist
Jurisdiction: National
Date: 2024-07-26
Topic: Consumer Protection

This checklist takes a defective-vehicle claim from the first repair visit through resolution, in nine phases, with the paperwork discipline that decides these cases placed first. Phase 1 is the repair visit itself and the three things that must appear on every repair order, and Phase 2 is the file: contract, buyers guide, itemization, add-on contracts, advertisements, and the one-page timeline. Phase 3 is the threshold analysis against the state lemon law, and Phase 4 is the manufacturer notice, which defeats more claims than any other requirement. Phase 5 covers the parallel federal warranty claim and its fee provision, and Phase 6 covers used vehicles, where as-is, implied warranty, and revocation of acceptance do the work instead. Phase 7 covers odometer, title, and recall claims, including the treble-damages remedy that is among the least used in federal consumer law. Phase 8 covers informal dispute resolution and settlement, and Phase 9 covers repossession and the deficiency audit. Five model letters, a deadline table, and a ranked failure-mode list are included.

How to use this checklist

Nine phases. Each has - [ ] items and a Why it matters, and the traps note. A fictional case — Rosalind Ferrante and a crossover with an intermittent electrical fault — runs throughout.

Doctrine is in Motor Vehicle Law for Consumers: A Comprehensive Guide to Sales, Financing, Warranties, and Lemon Laws. The narrative is The Most Expensive Contract Most People Never Read: Buying and Financing a Car. The materials are in The Motor Vehicle Consumer Toolkit.

Phase 1 — Every repair visit

[ ] Insist that the visit generate a written repair order, every time.
[ ] Ensure the complaint is recorded in your words, not the advisor's paraphrase.
[ ] Confirm the repair order records the date in and the date out.
[ ] Confirm it records the mileage.
[ ] Describe the symptom concretely: what happens, when, how often, at what speed, under what conditions.
[ ] Ask that the same defect language be used at each visit.
[ ] Get a copy before you leave.
[ ] Photograph or record the symptom when it occurs.
[ ] Keep a loaner and rental log — days out of service count.
[ ] Never accept "could not duplicate" without the complaint being written down anyway.

Why it matters, and the traps. A visit that generated no paperwork did not happen. Lemon law thresholds are counted in repair attempts and days out of service, and both are proved from repair orders.

The paraphrase problem is the biggest single defect in these files. A consumer says "the dashboard goes completely dark while I'm driving, about twice a week, usually after twenty minutes." The advisor writes "customer states check engine light." Two years later the record shows four visits for a warning lamp rather than four visits for an intermittent electrical failure that disables the instrument cluster at speed — and "substantial impairment of use or safety" becomes much harder to prove.

Consistency matters too. Four visits described four different ways may not count as four attempts on the same defect.

Worked example. Rosalind has four visits over five months, twenty-two days out of service. Three generated repair orders describing "check engine light." The fourth generated nothing — a verbal report at the counter. The fix going forward: insist on paperwork, insist on her own words, and reconstruct what she can from calendar entries, texts to the service advisor, and rental invoices.

Phase 2 — Build the file

[ ] Every page of the retail installment contract or lease.
[ ] The itemization of amount financed, with each add-on separately priced.
[ ] The Buyers Guide for a used vehicle — 16 C.F.R. part 455.
[ ] Every add-on contract: service contract, gap, and the rest, with cancellation terms.
[ ] The written warranty and any manufacturer booklet.
[ ] The credit application as submitted, if obtainable.
[ ] Any adverse action notice — 15 U.S.C. § 1691, 12 C.F.R. part 1002.
[ ] Advertisements for this specific vehicle, saved with dates.
[ ] Written or recorded salesperson representations, including texts.
[ ] Every repair order, in date order.
[ ] Rental, loaner, and towing invoices.
[ ] The title history and any commercial report, with the date pulled.
[ ] A one-page timeline: one line per event, with dates.

Why it matters, and the traps. The timeline answers, at a glance, every threshold question: how many attempts, how many days out, whether the coverage period was open, and which limitations clock applies to which claim.

Reconstructing a timeline two years later from memory is how provable claims become unprovable ones.

Phase 3 — The threshold analysis

[ ] Identify your state's repair-attempt threshold for the same defect.
[ ] Identify the days-out-of-service threshold.
[ ] Confirm the coverage period — time and mileage — and whether it runs from delivery or first repair.
[ ] Assess substantial impairment of use, value, or safety.
[ ] Confirm the defect is the same defect across attempts.
[ ] Determine whether your state covers used vehicles, and on what terms.
[ ] Determine whether the statute covers leased vehicles.
[ ] Determine whether a shorter threshold applies to safety-related defects.
[ ] Identify the remedy formula and the mileage offset.
[ ] Identify whether fees and any civil penalty are available.

Why it matters, and the traps. Substantial impairment is the contested element in most cases, and it is proved with specifics: a defect that disables the instrument cluster at highway speed is a safety impairment; a rattle is not. Describe the consequence, not the symptom.

Many statutes apply a shorter threshold — sometimes a single attempt — to defects likely to cause death or serious injury. Check before assuming four attempts are required.

Phase 4 — The manufacturer notice

[ ] Determine who must receive notice — almost always the manufacturer, not the dealer.
[ ] Determine the required form and content.
[ ] Determine whether a final repair opportunity must be offered.
[ ] Send it in writing, with proof of delivery.
[ ] Attach the repair orders.
[ ] State the defect, the attempts, the days out of service, and the remedy sought.
[ ] Calendar the response period.
[ ] Send it now if it has not been sent — the coverage period may still be open.

Why it matters, and the traps. This requirement defeats more lemon law claims than any other. A consumer with six repair orders and no notice letter frequently has no claim at all.

Notice to the dealer is not notice to the manufacturer. The dealer is a separate business, and the statute means what it says.

Phase 5 — The federal warranty claim

[ ] Identify the written warranty — 15 U.S.C. § 2301.
[ ] Check disclosure compliance — 15 U.S.C. § 2302, 16 C.F.R. part 701.
[ ] Check whether it is designated "full" and meets the standards — 15 U.S.C. § 2304.
[ ] If a written warranty or service contract was given, implied warranties may not be disclaimed — 15 U.S.C. § 2308.
[ ] Check for improper tie-in service or branded-part conditions — 16 C.F.R. part 700.
[ ] Preserve the private action with attorney fees — 15 U.S.C. § 2310.
[ ] Determine whether a compliant informal dispute mechanism must be used first — 16 C.F.R. part 703.

Why it matters, and the traps. The fee provision is why these cases exist. A $3,000 repair claim cannot support a lawyer; the same claim with fee-shifting can.

Section 2308 is the sleeper. A dealer that sold a service contract cannot also sell "as is," and a great many used-vehicle files contain exactly that combination.

Phase 6 — Used vehicles

[ ] Compare the Buyers Guide to the contract; the Guide overrides contrary terms.
[ ] Confirm the Guide was in the language of the negotiation.
[ ] Identify any express warranty created by a specific factual statement.
[ ] Assess the implied warranty of merchantability — fit for ordinary purpose.
[ ] Assess fitness for a particular purpose where the seller knew and the buyer relied.
[ ] Consider revocation of acceptance where a non-conformity substantially impairs value.
[ ] Determine whether your state prohibits as-is sales or imposes a statutory minimum warranty.
[ ] Identify fraud — any affirmative misrepresentation about condition, history, or use.
[ ] Identify the state deceptive practices claim and its multiplier and fee provision.
[ ] Check whether the dealer is bonded; the bond is frequently the only collectable asset.
[ ] Get an independent written diagnosis and the vehicle's prior service history.

Why it matters, and the traps. "As is" is not a shield against fraud, does not disclaim express warranties, does not operate at all where a written warranty or service contract was sold, and does not cure a concealed title brand.

Revocation of acceptance is genuinely powerful and badly underused. Where the non-conformity substantially impairs value and was accepted without discovery or on a promise to cure, the buyer may revoke within a reasonable time and recover the price.

Phase 7 — Odometer, title, and recall

[ ] Compare the disclosed reading against every dated record: prior titles, inspections, service history, auction listings.
[ ] Confirm the disclosure requirements were met — 49 U.S.C. § 32701, 49 U.S.C. § 32705.
[ ] Assess the remedy — treble damages or the statutory minimum, plus fees — 49 U.S.C. § 32710.
[ ] Pull the national title history for brands applied in any state.
[ ] Compare it to the representations on the sales documents.
[ ] Check the identification number against the recall database.
[ ] Confirm recall repairs are free regardless of age or ownership — 49 U.S.C. § 30118, 49 C.F.R. part 573.
[ ] Confirm all three identification numbers — dash, door jamb, title — match.

Why it matters, and the traps. The odometer remedy is one of the strongest in federal consumer law and among the least used. It requires intent to defraud, and the evidence is usually sitting in dated records nobody assembled.

Title washing across state lines means a single-state check is inadequate.

Phase 8 — Resolution

[ ] Determine whether informal dispute resolution is a prerequisite — 16 C.F.R. part 703, 15 U.S.C. § 2310.
[ ] Confirm whether the program's decision binds you, the manufacturer, or both.
[ ] Calculate the repurchase figure including the statutory mileage offset.
[ ] Include collateral costs: towing, rental, storage, finance charges.
[ ] Confirm the lienholder is paid and the title cleared.
[ ] Confirm the credit reporting consequence of a repurchase.
[ ] Preserve the fee claim in any settlement.
[ ] Get everything in writing before surrendering the vehicle.
[ ] Confirm cancellation and prorated refunds of the service contract and gap coverage.

Why it matters, and the traps. Participation in a manufacturer program is typically non-binding on the consumer and binding on the manufacturer — worth knowing before deciding whether to use one.

Unearned add-on refunds are routinely forgotten at repurchase, and they are real money.

Phase 9 — If it went to repossession

[ ] Determine whether the repossession breached the peace.
[ ] Check the notice of disposition for statutory compliance.
[ ] Assess commercial reasonableness of the sale — method, manner, time, place, terms.
[ ] Demand the deficiency itemization.
[ ] Audit: payoff, repossession and storage, reconditioning, auction fees, sale price and how determined.
[ ] Trace every fee to an authorizing contract provision.
[ ] Confirm credit for unearned service contract and gap refunds.
[ ] Apply collection defenses — 15 U.S.C. § 1692g, 15 U.S.C. § 1692e.
[ ] Check the credit reporting — 15 U.S.C. §§ 1681–1681x, 12 C.F.R. part 1022.
[ ] Consider the Holder Rule against a solvent holder — 16 C.F.R. part 433.

Why it matters, and the traps. Deficiency balances are miscalculated more often than not, and a defective disposition notice can bar the deficiency entirely in many states.

The Holder Rule means claims against the dealer are assertable against whoever holds the paper — which matters most when the dealer is gone. See Disputing a Credit Report Error and Defending a Debt Collection Suit: A Practical Checklist.

Model language

A. Repair order instruction

"Please record my complaint as follows, in these words: 'While driving, the instrument cluster goes completely dark and all gauges stop functioning. This has occurred approximately twice weekly, generally after twenty to thirty minutes of driving, at speeds above forty miles per hour.' Please also record today's date, the mileage, and the date the vehicle is returned to me, and please provide me a copy before I leave."

B. Manufacturer notice

"This is notice under [state statute] regarding [year/make/model], VIN [number], purchased [date] from [dealer]. The vehicle has a defect that substantially impairs its use and safety: [description]. It has been presented for repair of this defect on [dates], for a total of [N] days out of service. Repair orders are enclosed. The defect has not been corrected. I request [repurchase / replacement] under [statute]. If a final repair opportunity is required, please advise within [N] days where and when to present the vehicle."

C. Federal warranty demand

"This is a demand under 15 U.S.C. § 2310. [Vehicle] is covered by [warranty]. It has been presented for repair of [defect] on [dates] without correction, and the warrantor has failed to comply with its obligations. I demand [remedy], and I preserve my claim for costs and attorney fees under § 2310(d)(2). If [manufacturer] maintains an informal dispute settlement mechanism complying with 16 C.F.R. part 703, please identify it."

D. Used vehicle demand

"On [date] I purchased [vehicle] from you. I was told [specific representation]. The Buyers Guide posted on the vehicle stated [terms]. [Defect] appeared on [date], [N] days after purchase, and an independent inspection dated [date] concludes [finding]. Because you sold [a written warranty / a service contract], implied warranties could not be disclaimed under 15 U.S.C. § 2308. I demand [repair / refund / rescission] within [N] days, and I preserve claims under [state deceptive practices act] and 15 U.S.C. § 2310."

E. Deficiency itemization demand

"I have received a demand for a deficiency of $[amount] following the repossession and sale of [vehicle]. Please provide a complete itemization: the payoff at repossession; repossession, storage, and transport charges; reconditioning; auction or sale fees; the sale price and the method by which the vehicle was sold; each fee with the contract provision authorizing it; and the credit applied for unearned service contract and gap coverage refunds. Please also provide a copy of the notice of disposition and proof of its mailing."

Failure modes, ranked

Letting a visit generate no repair order.
Allowing the advisor's paraphrase to replace your description of the defect.
Missing the manufacturer notice.
Describing the defect differently at each visit, breaking the "same defect" count.
Not counting days out of service, which is an independent trigger.
Treating "as is" as the end of the inquiry.
Missing 15 U.S.C. § 2308 where a service contract was sold.
Not pulling the title history across states.
Not cross-checking the odometer against dated records.
Ignoring the fee-shifting claims, which determine viability.
Forgetting unearned add-on refunds at repurchase or in a deficiency.
Not checking the dealer bond, frequently the only collectable asset.

Rosalind, worked end to end

The running example is worth following all the way through, because it shows how a file that looked hopeless in month six became a repurchase in month eleven.

Month 1–5, what actually happened. Four service visits for an intermittent electrical fault that blanks the instrument cluster while driving. Three generated repair orders reading "customer states check engine light." The fourth generated nothing at all — she reported it at the counter, was told to bring it back if it recurred, and drove away. Twenty-two days total with the vehicle unavailable, spread across the four visits. No letter to anyone.

Month 6, the diagnosis of the file. Running Phase 3 against her state's statute: threshold is four repair attempts for the same defect, or thirty cumulative days out of service, within twenty-four months or 24,000 miles. She is at month six and 14,000 miles, so the coverage period is open. She is at twenty-two days, short of thirty. And she has three documented attempts, not four, all described as a warning lamp rather than an electrical failure.

The three problems, and the fixes.

Problem one: the fourth visit is invisible. Fix: reconstruct it. Her calendar shows the date. A text message to the service advisor that morning describes the symptom. The loaner agreement is in her email. That combination will not create a repair order, but it establishes the visit occurred and what was reported.

Problem two: the defect is described wrong. Fix: from this point forward, Phase 1 discipline. She writes out the description in advance and hands it to the advisor. The next repair order reads, in her words, that the instrument cluster goes completely dark at highway speed. That single change converts the claim from a warning-lamp nuisance into a safety impairment — and her state, like many, applies a lower threshold to defects likely to cause serious injury.

Problem three: no notice. Fix: send it now, in the form of Model Letter B, to the manufacturer, with all repair orders attached and the reconstructed fourth visit described. The coverage period is still open, which it would not have been six months later.

Month 7. The manufacturer designates a repair facility for the final attempt required by the statute. The fault is not reproduced during the visit. The vehicle is returned. Rosalind documents the visit, the dates, and the outcome.

Month 8. The fault recurs twice in one week, both times photographed. She sends a short supplemental notice attaching the photographs, the new repair order, and the running day count, now at thirty-one.

Month 9. She submits to the manufacturer's informal dispute resolution program, having confirmed under Phase 8 that the decision binds the manufacturer but not her. She brings the timeline, the repair orders, the photographs, and the notice correspondence — organized, dated, and in one place.

Month 11. Repurchase, with the statutory mileage offset, plus towing and rental costs, plus prorated refunds of the service contract and gap coverage that she had to ask for specifically because nobody offered them.

What made the difference. Not a new fact about the car. The car was always defective. What changed was that the defect finally appeared in the record in the words that matched the statute, the notice went to the right recipient while the window was open, and the days out of service were counted by someone who knew they were a separate trigger.

The five-minute intake questions

Whether you are the consumer or the lawyer, these answer whether there is a claim before anyone spends money.

New or used? Determines whether the lemon law applies at all in most states.
When purchased, and current mileage? Determines whether the coverage period is open.
How many repair visits for the same problem, and do repair orders exist for each? The threshold, and whether it is provable.
How many days was the vehicle unavailable? The independent trigger nobody counts.
Has anything been sent to the manufacturer in writing? The requirement that defeats most claims.
Was a written warranty or a service contract sold? If yes, 15 U.S.C. § 2308 forecloses an as-is disclaimer and the federal claim under 15 U.S.C. § 2310 carries fees.
What did the salesperson say, and is any of it in writing? Express warranty and fraud.
Does the defect affect safety? Frequently a lower threshold.
Is the dealer still in business, and is it bonded? Collectability.
Who holds the loan? 16 C.F.R. part 433 reaches them.

Question 4 deserves emphasis. Days out of service is an independent path to the threshold, it is proved from the same repair orders, and it is almost never tracked by consumers — who count repair visits and stop there. A vehicle that has been in the shop three times for eleven days each has not met a four-attempt threshold, and has comfortably exceeded a thirty-day one.

Three sentences worth memorizing

"Please write that on the repair order in my words, and give me a copy before I leave." — the sentence that builds the case.

"How many days has the vehicle been unavailable?" — the trigger nobody counts.

"Send the notice to the manufacturer, not the dealer." — the requirement that defeats more claims than any other.
