Counting Fifteen Business Days, Then Seven More, on the Massachusetts Lemon Law Calendar

Three measuring sticks inside one Massachusetts case file

A Massachusetts new car lemon law file runs on three measuring sticks at once, and none of them converts cleanly into the others. One counts business days. One counts plain calendar days. One counts months and miles. A history that clears the first stick can still miss the second, and an owner well inside the mileage figure can already be outside the filing window.

That is not a drafting accident. Massachusetts General Laws Chapter 90, Section 7N1/2 defines a business day for itself, keyed to something that varies by brand and town. The definition in subsection (1) reads "any day during which the service departments of authorized dealers of the manufacturer of the motor vehicle are normally open for business." Saturdays, Sundays and state holidays are not mentioned. Service departments are.

The outer boundary is measured a third way. The same paragraph sets the "Term of protection" at "one year or fifteen thousand miles of use from the date of original delivery of a new motor vehicle, whichever comes first; or, in the case of a replacement vehicle provided by a manufacturer to a consumer under this section, one year or fifteen thousand miles from the date of delivery to the consumer of said replacement vehicle, whichever comes first." The replacement-vehicle half is what gets dropped when the definition is quoted short, and it is the half that sets the start date for an owner already on a second car.

What follows describes published statutory and regulatory text, section by section. It is not legal advice, and the person writing it is not a lawyer. Anyone with a live dispute should read the sections named here and speak with someone licensed in Massachusetts.

Three measuring sticks in the Massachusetts lemon law Column one lists limits counted in business days: 15 days out of service for a new car and a 7 business day final cure opportunity, both counted only on days the dealer service department is normally open, and 10 business days out of service for a used car, counted Monday to Friday except state and federal holidays. Column two lists arbitration steps counted in plain days: 7, 10, 10, 44 and 45. Column three lists the outer limits in months and miles: one year or 15,000 miles of term of protection, 18 months to request new car arbitration, and 6 months to request used car arbitration. Three measuring sticks, one case file Eligibility is set in business days. Arbitration procedure is set in plain days. The outer limits are months and miles. Business days 15 out of service, new car 7 final cure opportunity 10 out of service, used car New car: days the dealer service department is normally open. Used car: Monday to Friday, less state and federal holidays. Plain days 7 acceptance notice mailed 10 respondent response 10 notice before hearing 44 hearing held within 45 decision mailed within Months and miles 1 year or 15,000 miles term of protection 18 months to request new car arbitration 6 months to request used car arbitration Sources: M.G.L. c. 90, s. 7N1/2 and s. 7N1/4; 201 CMR 11.02, 11.04 and 11.11.

A business day here is set by the service department, not by the courthouse

The federal rule on informal dispute settlement mechanisms borrows a working-day unit without writing the loan down. Its definitions section, Electronic Code of Federal Regulations, 16 CFR 703.1, defines eight terms, lettered (a) through (h), and neither business day nor working day is among them. Yet 16 CFR 703.5(h) instructs that "the Mechanism shall ascertain from the consumer within 10 working days of the date for performance whether performance has occurred."

Massachusetts wrote the unit into the lemon law instead. If the authorized dealers of that manufacturer normally open their service departments on Saturday, Saturday counts; if the service department shuts for a week, that week adds nothing, though the owner spent it without a car. The measure tracks the repair shop schedule, which is why the shop paperwork carries so much weight, a point traced in A DMV Rule, Not the Lemon Law, Sets What a Repair Invoice Must Show.

The definition is plural and set at the manufacturer level, keyed to the "service departments of authorized dealers of the manufacturer of the motor vehicle" rather than to the single store holding the car. The arbitration regulation supplies no competing definition; 201 CMR 11.01 defines six other terms and leaves business day alone, so each statute's own definition governs the requests filed under it.

The fifteen-day count and the seven-day cure share one definition

Subsection (4) builds the presumption in one long sentence, and the proviso sits at its end. In full: "A reasonable number of attempts shall be deemed to have been undertaken to conform a motor vehicle to any applicable express or implied warranties if (a) the same nonconformity has been subject to repair three or more times by the manufacturer or its agents or authorized dealers within the term of protection, but such nonconformity continues to exist or such nonconformity has recurred within the term of protection, or (b) the vehicle is out of service by reason of repair of any nonconformity for a cumulative total of fifteen or more business days during the term of protection; provided, however, that the manufacturer shall be afforded one additional opportunity, not to exceed seven business days, to cure any nonconformity arising during the term of protection, notwithstanding the fact that such additional opportunity to cure commences after the term of protection."

Three things sit in that proviso. The seven-day cure uses the same business days as the fifteen, so one service department schedule governs both. The cure attaches to a nonconformity "arising during the term of protection", tying the defect rather than the repair visit to the protected period. And the cure window may open after the term has expired, so an owner who reaches day fifteen at eleven months and three weeks does not lose the step.

The same subsection extends all three counts together, stating that "The term of protection, said fifteen business day period and said additional opportunity to cure shall be extended by any period of time during which repair services are not available to the consumer as a direct result of a war, invasion, fire, flood or other natural disaster." A second sentence extends the same three counts for a strike, with a condition attached: it applies "provided, however, that the manufacturer, its agent, or authorized dealer provides or makes provision for the free use of a vehicle to any consumer whose vehicle is out of service by reason of repair during a strike." Read the proviso and the strike extension is paired with a loaner obligation.

Where the seven business day cure opportunity sits Step one, report the nonconformity to the manufacturer, agent or authorized dealer during the term of protection. Step two, the same nonconformity is repaired 3 or more times, or the vehicle is out of service 15 or more cumulative business days. Steps one and two must fall within the term of protection. Step three, the manufacturer is afforded one additional opportunity not to exceed 7 business days to cure, and that step may commence after the term of protection ends. Arrows run left to right from step one to step three. Where the seven business day cure sits M.G.L. c. 90, s. 7N1/2(2) and (4). The proviso lets the last step begin after the term of protection. Step 1 Report the nonconformity to the manufacturer, agent or authorized dealer during the term of protection Step 2 Same nonconformity repaired 3 or more times, or out of service 15 or more cumulative business days Step 3 Manufacturer afforded one additional opportunity, not to exceed 7 business days, to cure Both must fall within the term of protection May commence after it ends The term of protection, the fifteen business day period and the additional opportunity to cure are all extended by time when repair services are unavailable as a direct result of a war, invasion, fire, flood or other natural disaster.

What the record has to show

Subsection (2) puts the trigger on the owner in a single clause: the duty to repair arises "If a motor vehicle does not conform to any applicable express or implied warranty, and the consumer reports the nonconformity to the manufacturer of the vehicle, its agent or its authorized dealer during the term of protection, the manufacturer, its agent or its authorized dealer shall effect such repairs as are necessary to conform the vehicle to such warranty." The reporting, not the fixing, has to land inside the term, and a report to the authorized dealer counts, since the three are named in the alternative.

Subsection (5) removes one notice step: "No consumer shall be required by any manufacturer, its agent or its authorized dealer to give notice directly to a manufacturer of the existence of any nonconformity before resorting to state-certified, new car arbitration." That is a narrow bar aimed at a notice-of-existence precondition, and it sits beside the cure opportunity in subsection (4) rather than cancelling it. A state that builds a manufacturer-directed clock into its statute shows the contrast, one such mechanism being worked through in When a Repair Refusal Starts New York’s Twenty-Day Clock at the Manufacturer.

The record requirements become concrete in the arbitration regulation. Cornell Legal Information Institute, 201 CMR 11.02 Arbitration Requests sets out what a new car request must state. Item (d) requires the consumer to "state that the consumer either gave the manufacturer, the agent or authorized dealer at least three attempts to correct the same substantial defect, or that the vehicle was out of service by reason of repair for at least 15 business days within the term of protection". Item (e) requires a statement that "the consumer gave the manufacturer its seven business day final opportunity to cure the non-conformity(s) after the limits set forth in 201 CMR 11.02(2)(d) were met or exceeded". The ordering is explicit: the cure follows the threshold rather than replacing it.

For the file itself, each visit needs a date in, a date out, the defect complained of, and enough detail to show one nonconformity recurring rather than three unrelated problems. A repair order recording only the write-up date leaves the cumulative out-of-service tally unprovable.

The arbitration clock switches to plain days

Once a request is filed, the unit changes. Under Massachusetts Office of Consumer Affairs and Business Regulation, 201 CMR 11.00 New and Used Motor Vehicle Arbitration, section 11.03(3) provides that complying, complete, reviewed forms are date-stamped, and that "This acceptance date shall trigger the 45 day period in which the arbitrator must render a decision in the case." Section 11.11(4) repeats it from the other side: "The arbitrator shall mail a decision in each case within 45 days of the acceptance date stamped on the request for arbitration form."

Between those points, 201 CMR 11.04 sets a compressed sequence. Notice of acceptance goes to both sides "within seven days of acceptance of a request for arbitration" under 11.04(2). The respondent manufacturer or dealer has ten days from that notice to mail a specific response. Pre-hearing notice of date, time, location and arbitrator name goes out no later than ten days before the hearing. And 11.04(4) provides that "The hearing shall be held within 44 days of the date that the request for arbitration was accepted."

None of those five numbers is written as a business day. Seven, forty-four and forty-five run from the stamped acceptance date; the respondent’s ten runs from the date of the notice of acceptance, and the pre-hearing ten runs backward from the hearing.

The outermost limit differs again. Subsection (6) provides that "All manufacturers shall submit to state-certified, new car arbitration, if such arbitration is requested by the consumer within eighteen months from the date of original delivery to such consumer of a new motor vehicle." The regulation states the same limit with a different anchor, requiring that the form be "received by the arbitration firm or OCABR within 18 months of the date the owner took possession of the motor vehicle (for new cars)". Original delivery and the date of possession are usually one day, not one phrase.

The used vehicle warranty counts its own ten

Massachusetts runs a second statute for used cars, and it counts differently. Massachusetts General Laws Chapter 90, Section 7N1/4 requires a dealer to sell a used vehicle with an express written warranty and sets its length by mileage at the time of sale. Under 40,000 miles the term is "ninety days or three thousand seven hundred and fifty miles, whichever occurs first." That warranty, the statute adds, "is in addition to any right the consumer may have under section seven N1/2." From 40,000 up to 80,000 miles it is sixty days or two thousand five hundred miles; from 80,000 up to 125,000 miles, thirty days or one thousand two hundred and fifty miles.

The repurchase trigger uses ten business days rather than fifteen, and Section 7N1/4 defines that unit in its own subsection (1) as "Monday to Friday, inclusive, except for state or federal holidays", not by service department hours: "If the dealer fails to repair the same defect within three attempts, or if the used motor vehicle is out of service for more than a cumulative total of ten business days after the consumer has returned it to the dealer for repair of the same, then the dealer shall accept return of the vehicle from the consumer and refund the full repurchase price, less a reasonable allowance for use." The clause reads more than ten, not ten or more.

The filing window is shorter too. Under 201 CMR 11.02(3)(a), a used car request must "be submitted within six months of the date the consumer took possession of the motor vehicle (for used cars)." Six months against eighteen, and ten business days against fifteen.

Massachusetts used vehicle warranty terms by mileage at sale Three mileage tiers under M.G.L. c. 90, s. 7N1/4. Under 40,000 miles at sale: 90 days or 3,750 miles, whichever occurs first. From 40,000 to under 80,000 miles: 60 days or 2,500 miles. From 80,000 to under 125,000 miles: 30 days or 1,250 miles. Day bars and mile bars use separate scales; within each series the bar length is in proportion to the value. Used vehicle warranty terms, by mileage at sale M.G.L. c. 90, s. 7N1/4. Each tier runs to whichever of the two figures occurs first. Under 40,000 miles at time of sale 90 days 3,750 miles 40,000 to under 80,000 miles at time of sale 60 days 2,500 miles 80,000 to under 125,000 miles at time of sale 30 days 1,250 miles Days of warranty coverage Miles of warranty coverage Day bars and mile bars use separate scales. Within each series, bar length is in proportion to the value shown.

Where this framework does not apply

Both statutes carry scope limits in their definitions. Under Section 7N1/2(1), "Motor vehicle" or "vehicle" means "any motor vehicle as defined in section one sold, leased or replaced by a dealer or manufacturer after the effective date of this section, except that it shall not include auto homes, vehicles built primarily for off-road use or any vehicle used primarily for business purposes." The business-use exclusion turns on primary use rather than on titling or financing.

The used vehicle statute draws its own line, defining "Used motor vehicle" or "used vehicle" as "any vehicle driven more than the limited use necessary in moving or road testing a new vehicle prior to delivery to a consumer, including a demonstrator vehicle, except that it shall not include auto homes, vehicles built primarily for off road use, motorcycles, or any vehicle used primarily for business purposes." A demonstrator vehicle is pulled in by name; motorcycles are pushed out. The mileage tiers stop at one hundred and twenty-five thousand miles, and the section "shall not apply to any used motor vehicle sold by a dealer to a consumer for less than seven hundred dollars."

Consumer, by contrast, is drawn broadly: a buyer or lessee other than for resale, plus any person to whom the vehicle is transferred during an applicable warranty.

Numbers to Re-check

Each figure here is published text, worth pulling from the source before it is relied on. The term of protection runs one year or fifteen thousand miles from original delivery, whichever comes first, or from delivery of a replacement vehicle where one was provided. The new car thresholds are three or more repairs of the same nonconformity, or fifteen or more cumulative business days out of service, either one inside the term; the cure window is not to exceed seven business days and may commence after the term of protection.

The filing limits are eighteen months for new car arbitration and six months for used. The used car figures are three attempts or more than ten cumulative business days, against warranty terms of ninety days or three thousand seven hundred and fifty miles, sixty days or two thousand five hundred miles, and thirty days or one thousand two hundred and fifty miles. The arbitration sequence runs seven days to notice of acceptance, ten days for the respondent response, ten days of pre-hearing notice, forty-four days to the hearing, and forty-five days to a mailed decision.

One figure sits outside the counting question. Subsection (3) builds the reasonable allowance for use, for vehicles other than motorcycles, on a fraction with a denominator of one hundred thousand and a numerator of the mileage travelled before the manufacturer accepted return.

Where This Doesn’t Apply

Counting business days by service department hours helps only where the statute uses that unit. It is the wrong tool for the arbitration calendar, where the regulation says days and means days. It is the wrong tool for the eighteen-month and six-month filing limits, which run in months from a delivery or possession date. And it has no bearing on the mileage side of the term of protection, which does not pause while the car sits in the shop.

The framework is also state-bound. Sections 7N1/2 and 7N1/4 are Massachusetts statutes, and other states define their day counts in their own terms; a federal claim under the Magnuson-Moss Warranty Act runs on a different structure, with 16 CFR Part 703 governing a manufacturer-sponsored mechanism rather than the state-certified program described here.

A description of statutory text is not a prediction of outcome either. It does not say how any arbitrator or court has applied them to a particular repair history, and it is not legal advice.

Four Repair Attempts Create a Presumption in California, Not an Automatic Buyback

A California owner whose new vehicle has been in the shop four times for the same defect is often told the car "qualifies as a lemon." The statute says something narrower. Four repair attempts inside a defined window create a rebuttable presumption that a reasonable number of attempts has been made. A presumption is an evidentiary starting position, not an entitlement to a check. Understanding the difference determines what a repair file has to prove, and it explains why two owners with identical repair histories can end up in very different positions. The window comes first, and it is short Civil Code section 1793.22, the Tanner Consumer Protection Act, opens every one of its thresholds with the same clause: the qualifying events must occur within 18 months from delivery to the buyer or 18,000 miles on the odometer, whichever occurs first . Not 18 months and 18,000 miles. Whichever arrives sooner closes the window. A commuter driving 1,600 miles a month reaches 18,000...

Texas Lemon Law Deadlines Run on 24,000 Miles, Refunds on One Repair Order Date

Two vehicles can carry identical repair histories and land in different places under Texas law, because Chapter 2301 of the Texas Occupations Code measures its qualifying window from the date of original delivery and closes it on whichever arrives first, the calendar or the odometer. Section 2301.605 supplies the presumption — a rebuttable one, not an entitlement. A rule of the Texas Department of Motor Vehicles, 43 TAC §224.260, supplies the arithmetic, and its output turns on one date most owners never write down: the first report of the defect. What follows reads both, with section numbers and effective dates attached. Three Presumption Tests, One Shared Cutoff Section 2301.605(a) establishes the presumption “that a reasonable number of attempts have been undertaken to conform a motor vehicle to an applicable express warranty” if any of three conditions is met. The first, §2301.605(a)(1), is the four-attempt test: “the same nonconformity continu...

When Florida Counts 30 Days Out of Service, the 15-Day Letter Comes First

Florida’s motor vehicle warranty chapter does not convert a broken car into a refund on the third failed repair. It builds a presumption, and the presumption is what the state’s arbitration board works from. Section 681.104(3) of the Florida Statutes contains two ways to reach it, and they count different things: one counts repair attempts on a single defect, the other counts days the vehicle sat out of service for any number of defects. Each route carries its own written-notice step, sent by registered or express mail and addressed to the manufacturer rather than to the dealership doing the work. As printed in the 2026 Florida Statutes, section 681.104 closes with a history note whose last entry is s. 4, ch. 97-245, so the thresholds in that section have stood since 1997. Two Routes to the Presumption, and They Count Different Things The presumption is stated once and then splits in two. Section 681.104(3) opens: “It is presumed that a reasonable number of attemp...
