A DMV Rule, Not the Lemon Law, Sets What a Repair Invoice Must Show
New York's new car lemon law runs on counting. General Business Law section 198-a(d) makes a presumption available once a vehicle has been through a set number of repair attempts, or has sat out of service for a set number of days. Both counts are exact numbers, and both are measured inside a window that closes at eighteen thousand miles or two years, whichever arrives first.
What section 198-a never does is describe the piece of paper those counts are read from. The section has subdivisions running from (a) through (o): definitions, the duty to report a defect, the replacement and refund remedy, the presumption, tolling, arbitration requirements, motor home rules, and the notice a dealer hands over at delivery. None of them sets out what a repair invoice has to contain.
That requirement sits in a different body of law, written for a different reason. Vehicle and Traffic Law section 398-d requires a registered repair shop to produce an invoice, and the Commissioner's regulation at 15 NYCRR Part 82 lists what goes on it. Part 82 exists to police repair shops, not to resolve warranty disputes. It is administered by the Department of Motor Vehicles rather than by the Attorney General's lemon law program. The two schemes were built for separate purposes, and they meet on one document.
What the record has to show
The bridge between the two schemes is a single sentence buried near the end of the invoice rule. After a long list of required fields, 15 NYCRR 82.5(c) adds: "A repair performed under warranty requires an invoice which complies with this subdivision." That sentence matters because warranty work costs the consumer nothing, and the definition that pulls a business inside the scheme speaks of compensation. Vehicle and Traffic Law section 398-b(2) defines a repair shop as "any person who, for compensation, is wholly or partially engaged in the business of repairing or diagnosing motor vehicle malfunctions or repairing motor vehicle bodies, fenders or other components damaged by accident or otherwise, except that such term does not include:" followed by four narrow exclusions covering employees, single-company fleet shops, minor servicing such as oil and tire changes, and farm or road building machinery. A franchised dealer performing warranty repairs is not among them.
The Attorney General's own New Car Lemon Law guide states the same conclusion in plainer words: "Dealers are required by Department of Motor Vehicles (DMV) regulations to provide a legible and accurate written work order each time any repair work is performed on a car. This includes warranty work for which no charge is made."
Once that is settled, the field list in 15 NYCRR 82.5(c) stops looking like consumer protection boilerplate and starts looking like the evidentiary spine of a lemon law count. Six items do most of the work.
- Two odometer readings, not one. The invoice must show "the odometer reading on the vehicle at the time it was left with the repair shop and the odometer reading at the time the invoice was prepared". Section 198-a measures its window against the first eighteen thousand miles of operation, so the reading at drop-off is the one that places a visit inside or outside the window. The second reading records how far the shop drove the vehicle while it held it. The two figures are recorded separately because they answer different questions.
- Two dates, which bracket the shop's documented possession of the vehicle. The list opens with "the name, address and facility number of the repair shop, the date of the invoice, the date the vehicle was presented to the repair shop for repair or services". Section 198-a(d)(2) reaches its presumption when "the vehicle is out of service by reason of repair of one or more nonconformities, defects or conditions for a cumulative total of thirty or more calendar days during either period, whichever is the earlier date." The regulation does not use the phrase out of service, and it was not written with that count in mind. It simply happens to require the date the vehicle was presented and the date the invoice was prepared, which bracket the visit the count is built from without themselves fixing the day the vehicle returned to service.
- The symptom in the customer's own terms. Section 82.5(c) requires a description of the problem reported by the customer, and the estimate rule at 82.5(a) requires the same field, alongside "a description of the problem reported by the customer, and a statement informing the customer of his right to receive replaced parts if the customer makes a written request for such return". This is the field that separates a repeat of the same defect from four unrelated visits. Section 198-a(d)(1) attaches the presumption where "the same nonconformity, defect or condition has been subject to repair four or more times by the manufacturer or its agents or authorized dealers". Whether four visits are one nonconformity or four is often decided by how the complaint was written down at intake.
- Which shop did the work, stated by registration number. The invoice must carry the shop's name, address and facility number, and separately the repair shop registration number. Section 198-a(d)(1) counts repairs performed by the manufacturer, its agents, or its authorized dealers, so the identity of the facility is part of what makes an attempt countable under that paragraph.
- The terms of any guarantee on the work itself. Among the required fields is "the terms and time limit of any guarantee for the repair work performed". This is distinct from the manufacturer's express warranty. The DMV rule does not force a shop to guarantee anything, but if it does, the duration has to appear on the invoice.
- Verbal approvals get a timestamp. Section 82.5(b) closes the gap for work authorized by phone: "If the customer gives an oral work order, the oral work order shall be noted on the invoice and shall include the date, time and manner of authorization and by whom such authorization was given". A vehicle can sit at a dealership for days before anyone approves the work, and this notation is where that interval is documented.
Section 398-d(1) then fixes who holds the result: "One copy of the invoice shall be given to the customer and one copy shall be retained by the motor vehicle repair shop."
One required record never reaches the consumer
Not every document the statute calls for ends up in the owner's folder. Section 198-a(b)(1) imposes a reporting duty on the dealer that runs in the opposite direction, toward the manufacturer. Once a consumer reports a defect, "the agent or dealer shall within seven days forward written notice thereof to the manufacturer by certified mail, return receipt requested, and shall include in such notice a statement indicating whether or not such repairs have been undertaken".
That is a dated, certified record of the complaint, created by the dealer, held by the manufacturer, and generated by statute rather than by regulation. Nothing in subdivision (b)(1) directs a copy to the consumer. The invoice rules in Part 82 and this notice duty are two different paper trails about the same visit, kept in two different places.
A related sequence applies when a dealer will not start the work at all, which sets a twenty-day period running at the manufacturer. That path was covered separately in an earlier piece on New York's repair refusal provision, and it turns on certified mail rather than on invoices.
The duty to keep the paper ends before the deadline to sue does
The retention rule and the limitations period are set by different authorities, and they do not line up. Under 15 NYCRR 82.9(a), "Each motor vehicle repair shop shall maintain copies of estimates, work orders, invoices, parts purchase orders and appraisals prepared by that repair shop." The same subdivision fixes the term: "Such copies shall be kept for two years and shall be available for inspection by the commissioner or his designee during all business hours."
Section 198-a(j) sets a longer clock: "Any action brought pursuant to this section shall be commenced within four years of the date of original delivery of the motor vehicle to the consumer."
Two years of regulatory retention against four years to start an action leaves a stretch in which 15 NYCRR 82.9(a) no longer requires the shop to keep that copy available for the commissioner's inspection. Section 398-d(3) delegates the content of the retention duty to the commissioner's regulations, and section 398-d(1) states only that the shop retains a copy, without fixing a term. The consumer's copy, handed over under section 398-d(1), is not subject to any retention period at all. The DMV's consumer page tells owners to keep estimates, invoices, work orders, receipts, guarantees and warranties, and the Attorney General's guide tells them to keep copies of all work orders, repair bills and communications with the dealer or manufacturer. The arithmetic above is why that advice exists in both places.
One statutory adjustment moves the counting periods themselves. Section 198-a(e) provides that "The term of an express warranty, the two year warranty period and the thirty day out of service period shall be extended by any time during which repair services are not available to the consumer because of a war, invasion or strike, fire, flood or other natural disaster." The retention rule in Part 82 contains no matching extension.
Numbers to Re-check
Each figure below has a source that can change. Mileage thresholds and retention terms are amended by statute and by regulation on separate schedules, and the arbitration figures sit in a form that is revised by year.
| Figure | Where it comes from | What can move it |
|---|---|---|
| 18,000 miles or two years, whichever is earlier | GBL 198-a(b)(1) | Statutory amendment |
| Four or more repair attempts | GBL 198-a(d)(1) | Statutory amendment |
| Thirty or more calendar days out of service | GBL 198-a(d)(2) | Statutory amendment; extended under 198-a(e) |
| Seven days for the dealer's certified notice | GBL 198-a(b)(1) | Statutory amendment |
| First twelve thousand miles before a use deduction | GBL 198-a(c)(1) | Statutory amendment |
| Four years to commence an action | GBL 198-a(j) | Statutory amendment |
| Two-year record retention by the shop | 15 NYCRR 82.9(a) | DMV rulemaking |
| 250 dollar arbitration filing fee | Attorney General arbitration form, 2025 revision | Reissued form |
Primary texts for these figures: General Business Law section 198-a, Vehicle and Traffic Law section 398-d, the DMV text of Regulation Part 82, the DMV auto repair rights page, and the Attorney General's New Car Lemon Law guide. The mileage deduction in 198-a(c)(1) was examined on its own terms in an earlier piece.
Where this framework does not apply
A missing invoice is not a statutory disqualifier. This is the most important limit. Section 198-a(d) does not condition its counts on documentation. It speaks of repairs that occurred and days the vehicle was out of service, not of invoices that were issued. Part 82 imposes duties on shops, and the consequence of breaking them runs through the DMV registration scheme. Nothing quoted above converts a paperwork failure by a shop into a lost count for the owner, and nothing here states how any particular record would be weighed in a proceeding.
Documentation does not settle the contested element. Section 198-a(c)(3) provides that "It shall be an affirmative defense to any claim under this section that:" and then lists two: that the defect does not substantially impair the vehicle's value, and that it resulted from abuse, neglect, or unauthorized modification. A complete invoice file establishes dates, mileage and complaints. It does not resolve either defense.
Motor homes run on different numbers. Subdivision (n) sets its own scheme, and by its terms it governs where it conflicts with the rest of the section. Under 198-a(n)(6) the trigger arrives when "the same covered nonconformity, defect or condition in a motor home has been subject to repair two times or a motor home has been out of service by reason of repair for twenty-one days, whichever occurs first", at which point a certified mail report is required, with a proceeding available after three repair attempts or at least thirty days. That special notification requirement applies only where the manufacturer or dealer supplied a prior written copy of the requirement and the consumer acknowledged receipt in writing. Subdivision (n)(3) also excludes the living quarters of a motor home from the section. These figures belong to motor homes and were not written for passenger vehicles. Another state's motor home out-of-service provisions were taken up separately in an earlier piece, and no out-of-state text was examined for this article.
Part 82 reaches registered New York shops, not everyone who turns a wrench. Section 398-b(2) excludes shops serving a single commercial or industrial establishment or a government agency, businesses limited to fueling and minor servicing, and farm or road building machinery repairers. A repair performed outside the New York registration scheme will not generate a Part 82 invoice, even if the visit is otherwise relevant.
New vehicles only, under this section. Section 198-a(b)(1) addresses a new motor vehicle sold and registered in the state. New York's used car lemon law is a separate section with its own thresholds, and nothing above describes it.
New York only. Every provision cited here is New York law. Other states set their own repair attempt counts, out of service periods and record keeping rules, and none of those were examined for this piece. An earlier article looked at how Texas handles a thirty-day out of service count, and the differences there are a reminder that these frameworks are not portable.
What the overlap actually is
The relationship between the two schemes is not that one enforces the other. Section 198-a describes events and attaches consequences to their number. Part 82 describes a document and lists its contents. Neither text refers to the other. The overlap exists because both are describing the same afternoon at a service drive, and the regulation happens to require, field by field, the facts the statute happens to count: when the vehicle arrived, when it left, how far it had been driven, what the owner said was wrong, and who did the work.
That is also why the delivery notice in section 198-a(o) matters less than it looks. The dealer hands over a New Car Lemon Law Bill of Rights at purchase, printed in bold face type of at least eight points. It states the thresholds. It does not tell the buyer that the numbers in it will later be proved, or disproved, by a form that a completely different agency designed for a completely different reason.
