Mississippi Motor Vehicle Warranty Enforcement Act (Miss. Code § 63-17-151)

The Mississippi Motor Vehicle Warranty Enforcement Act is codified at Miss. Code § 63-17-151 through § 63-17-165. It is the workhorse state statute for Mississippi lemon-law claims — establishing the eligibility window, the repair-attempt presumption, the procedural prerequisites, and the refund/replacement remedy.

Structure of the statute

Section	Subject
§ 63-17-151	Short title — “Motor Vehicle Warranty Enforcement Act”
§ 63-17-153	Definitions (“nonconformity” = defect substantially impairing use, market value, or safety)
§ 63-17-155	Manufacturer warranty obligations
§ 63-17-157	Repair obligation and consumer’s reporting obligation
§ 63-17-159	Refund or replacement — 1-year Rights Period, 3-attempt / 15-working-day OOS presumption, 20¢/mile mileage offset, discretionary attorney fees, 18-month SOL
§ 63-17-161	Bad-faith plaintiff-side cost-shifting
§ 63-17-163	Mandatory IDS prerequisite (16 C.F.R. Part 703-compliant)
§ 63-17-165	Other rights and remedies

The 1-year Rights Period “whichever earlier”

§ 63-17-159 establishes the eligibility window as:

Within the terms, conditions or limitations of the express warranty, or during the period of one (1) year following the date of original delivery of the motor vehicle to a consumer, whichever expires earlier.

The 1-year statutory cap is substantially shorter than the typical manufacturer’s express warranty (typically 36 months / 36,000 miles bumper-to-bumper), so the 1-year period almost universally controls. This places MS at the short-Rights-Period tier alongside Tennessee, Illinois, Michigan, Wisconsin, Colorado, Massachusetts, Missouri, Nevada, Louisiana, Kentucky § 367.840 (12-mo/12K), and South Carolina § 56-28-30 (12-mo/12K). The short Rights Period creates urgency: defects must emerge and reach the 3-attempt or 15-working-day OOS threshold quickly.

The 3-attempt / 15-working-day OOS presumption

§ 63-17-159 establishes the rebuttable presumption when, within the Rights Period:

(a) the same nonconformity has been subject to repair three (3) or more times by the manufacturer or its agent and such nonconformity continues to exist; or (b) the vehicle is out of service by reason of repair of the nonconformity by the manufacturer or its agent for a cumulative total of fifteen (15) or more working days, exclusive of downtime for routine maintenance as prescribed by the owner’s manual, since the delivery of the vehicle to the consumer.

The 15-WORKING-DAY OOS threshold is among the SHORTEST in the country. Working-day counting (≈21 calendar days) is substantially more consumer-favorable than the 30-calendar-day peer-state tier (≈30 calendar days; used by CA/TX/FL/TN/PA/KY/CT/LA/NV). Mississippi joins Massachusetts’s 15-business-day OOS as the only states with 15-day OOS thresholds. See our repair-attempt presumption article for the working applications.

The 3-attempt track joins TN/MA/GA/VA/OR/SC/AR at the more-consumer-favorable 3-attempt tier (less consumer-favorable than 4-attempt jurisdictions like CA/KY/WA/NC/AZ/CO/WI/MN/IN/MD/MO/NV/LA).

§ 63-17-163 IDS prerequisite (mandatory)

This is the procedural choke point in Mississippi cases:

If a manufacturer has established an informal dispute settlement procedure which complies in all respects with the provisions of 16 C.F.R., Part 703, the provisions of Section 63-17-159 concerning refunds or replacements shall not apply to any consumer who has not first resorted to such procedure.

For most manufacturers, the certified IDS is BBB Auto Line. For Ford and Lincoln, it’s Ford DSB. Consumers cannot pursue § 63-17-159 refund/replacement remedies without first exhausting the IDS — making § 63-17-163 a procedurally rigid prerequisite. See our BBB Auto Line / Ford DSB article.

The 90-day post-IDS filing window under § 63-17-159(d) becomes critical timing once IDS completes.

§ 63-17-161 bad-faith plaintiff-side cost-shifting

§ 63-17-161 imposes plaintiff-side cost exposure for bad-faith claims:

Any claim by a consumer which is found by the court to have been filed in bad faith, or solely for the purpose of harassment, or in complete absence of a justiciable issue of either law or fact raised by the consumer, shall result in the consumer being liable for all court costs incurred by the manufacturer or its agent as a direct result of the bad faith claim.

This is structurally distinctive — most peer states don’t have plaintiff-side cost-shifting in the Lemon Law itself. The risk is real but limited in well-documented cases: courts uniformly require a clear absence of supporting evidence to make a bad-faith finding. The practical advice: document carefully, run IDS in good faith, and don’t pursue claims unsupported by repair-order documentation.

§ 63-17-159 distinctive 20¢/mile mileage offset

Most peer states use percentage-based mileage offset formulas. Mississippi’s § 63-17-159 uses a flat 20¢ per mile offset:

A reasonable allowance for use is twenty cents (20¢) per mile based on miles driven before the first repair attempt for the nonconformity.

For a $50,000 vehicle with 15,000 miles before the first repair attempt:

• MS 20¢/mile formula: $3,000 offset.
• California-style formula (price × miles ÷ 120,000): $6,250 offset.
• Net difference: MS’s flat formula is $3,250 more consumer-favorable for this vehicle.

For higher-priced vehicles, the advantage grows. For lower-priced vehicles ($20,000), the MS formula can be slightly less favorable than percentage-based formulas. Net: MS’s flat 20¢/mile is a distinctive consumer benefit for luxury / EV / premium-truck cases.

§ 63-17-159 discretionary attorney fees

§ 63-17-159 provides:

The court may allow [a prevailing consumer] to recover as part of the judgment a sum equal to the aggregate amount of costs and expenses, including attorney’s fees based on actual time expended, determined by the court to have been reasonably incurred by the plaintiff for or in connection with the commencement and prosecution of such action.

The “may allow” language is discretionary — among the weaker Lemon Law fee bases. Mississippi joins Kentucky § 367.844, Michigan § 257.1407(2), and South Carolina § 56-28-50 at the discretionary-fees tier. Combined with the structurally narrowed MCPA (which excludes prevailing plaintiff fees entirely), Mississippi’s state-law fee framework is substantially weaker than most peer states.

§ 63-17-159(d) — 18-month SOL

§ 63-17-159(d) provides one of the shortest action SOLs in the country:

Within one (1) year following expiration of the terms, conditions or limitations of the express warranty, or within eighteen (18) months following the date of original delivery of the motor vehicle to a consumer, whichever is earlier, or, if a consumer resorts to an informal dispute settlement procedure as provided in Sections 63-17-151 et seq., within ninety (90) days following the final action of the panel.

In practice the 18-month-from-delivery trigger usually controls (the 1-year-after-warranty-expiration would be ≈4 years from delivery, much later). See our SOL article.

§ 63-17-159 manufacturer 10-working-day cure window

After the consumer delivers the vehicle to the manufacturer-designated repair facility (typically the 3rd attempt), the manufacturer has 10 working days to conform the vehicle to the warranty. Failure to cure within this window triggers the refund/replacement obligation.

§ 63-17-159 affirmative defenses

The manufacturer can rebut the presumption by showing:

• The nonconformity does not substantially impair use, market value, or safety.
• The nonconformity was caused by abuse, neglect, or unauthorized modification.
• The consumer failed to deliver the vehicle to a designated repair facility.
• The consumer failed to exhaust § 63-17-163 IDS prerequisite.

Bottom line

Mississippi’s Motor Vehicle Warranty Enforcement Act is structurally consumer-favorable on the OOS threshold (15 working days = among shortest in country) and the mileage offset (flat 20¢/mile favors high-priced vehicles), but procedurally rigid (mandatory § 63-17-163 IDS exhaustion + § 63-17-161 bad-faith cost-shifting), and structurally weak on fees (discretionary § 63-17-159 + zero MCPA plaintiff fees). Combine with federal Magnuson-Moss for mandatory fee anchor and the structurally narrowed MCPA for the full MS claim package.
