Dear Sir or Madam:

This law firm represents [________________________________] ("Consumer" or "Client") in connection with the purchase/lease of the above-referenced vehicle. The vehicle qualifies as a "lemon" under the Missouri New Vehicles Warranty Law, RSMo §§ 407.560–407.579, and the federal Magnuson-Moss Warranty Act, 15 U.S.C. § 2301 et seq.

THIS LETTER CONSTITUTES THE WRITTEN NOTIFICATION TO THE MANUFACTURER REQUIRED UNDER RSMo § 407.563 BEFORE SEEKING STATUTORY RELIEF. Upon receipt of this notice, [MANUFACTURER] has ten (10) calendar days to cure the nonconformity before our Client is entitled to pursue refund, replacement, or litigation.

I. MISSOURI LEMON LAW — LEGAL FRAMEWORK

A. Statutory Authority: RSMo §§ 407.560–407.579

Missouri's lemon law is formally titled the Missouri New Vehicles Warranty Law, codified at RSMo §§ 407.560 through 407.579. It is part of Missouri's broader consumer protection framework under Chapter 407 (Merchandising Practices). The law requires manufacturers to honor their express warranties or provide a refund or replacement vehicle.

B. Covered Vehicles — RSMo § 407.560(4)

The Missouri Lemon Law covers:

☐ New motor vehicles sold or registered in Missouri
☐ Demonstrators for which a manufacturer's warranty was issued as a condition of sale
☐ Lease-purchase vehicles with a manufacturer's warranty issued as a condition of the lease

Vehicles EXCLUDED from Missouri Lemon Law coverage (RSMo § 407.560(4)):

☐ Commercial motor vehicles (over 12,000 lbs. GVWR used for business)
☐ Off-road vehicles
☐ Mopeds
☐ Motorcycles
☐ Recreational motor vehicles (motor homes) — EXCEPT their chassis, engine, powertrain, and component parts are covered

Important Distinction: Missouri's lemon law covers new vehicles only — used vehicles with a manufacturer's unexpired warranty may be covered under the Magnuson-Moss Warranty Act but not under Missouri's state lemon law.

C. Coverage Period — RSMo § 407.563

The nonconformity must be reported and the manufacturer given the opportunity to repair during the earlier of:

1. The term of the express warranty (e.g., 3 years/36,000 miles bumper-to-bumper); OR
2. One (1) year following the date of original delivery to the consumer

After the consumer provides written notice under RSMo § 407.563, the manufacturer has ten (10) calendar days to cure.

D. Statute of Limitations — RSMo § 407.573

Missouri's lemon law has a relatively short statute of limitations. A civil action must be filed within the earlier of:

1. Six (6) months following expiration of the express warranty term; OR
2. Eighteen (18) months following the date of original delivery to the consumer

If the consumer participates in an informal dispute settlement (arbitration) procedure, the action must be filed within ninety (90) days following the procedure's final action. Missouri's lemon law deadline is shorter than many other states — act promptly.

E. Presumption of Nonconformity — RSMo § 407.571

Missouri law creates a rebuttable presumption that a manufacturer has had a reasonable opportunity to repair when, within the coverage period, any of the following occurs:

☐ Four (4) or More Repair Attempts for Same Defect:
The same nonconformity has been subject to repair four (4) or more times by the manufacturer or its authorized agents, and the nonconformity continues to exist. RSMo § 407.571(1).

☐ Two (2) Repair Attempts for Life/Safety Defects:
The same nonconformity is likely to cause death or serious bodily injury if the vehicle is driven, and has been subject to repair two (2) or more times without success. RSMo § 407.571(2) (where applicable under the specific statutory language — verify current text with Missouri revisor).

☐ 30 or More Working Days Out of Service:
The vehicle has been out of service for repair for a cumulative total of 30 or more working days, exclusive of downtime for routine maintenance prescribed by the manufacturer. RSMo § 407.571(2).

Note: The 30-day out-of-service period may be extended if repair services are unavailable due to conditions beyond the manufacturer's control.

F. Consumer Remedies — RSMo § 407.565

If the presumption is met and the manufacturer fails to cure, the consumer may elect:

Option 1 — Refund:
The manufacturer must refund the full purchase/lease price (or capitalized cost), minus a reasonable use allowance, plus all collateral charges.

Option 2 — Replacement:
The manufacturer must provide a comparable new motor vehicle — same make, model, and specifications as reasonably available.

G. Use Allowance Formula — RSMo § 407.567

Missouri's use offset formula is specific. The reasonable use allowance is calculated as:

(Purchase Price) × (Mileage at First Report of Nonconformity ÷ 100,000)

This formula is set by statute. Missouri uses 100,000 miles as the denominator — favoring consumers more than states that use lower mileage denominators (e.g., 120,000 miles).

H. Informal Dispute Settlement — RSMo § 407.575

If [MANUFACTURER] has established an informal dispute settlement procedure complying with 16 C.F.R. Part 703, the consumer must exhaust that procedure before filing suit under the Missouri Lemon Law. The consumer does not waive any rights by participating, and the arbitration decision is not binding if the consumer is not satisfied with the outcome.

I. Attorney's Fees — RSMo § 407.579

A prevailing consumer is entitled to recover reasonable attorney's fees and costs under RSMo § 407.579. This provision makes Missouri lemon law claims economically viable even for lower-value vehicles.

J. Missouri Attorney General Arbitration Program

Missouri consumers may also access the Missouri Attorney General's informal arbitration program as an alternative to manufacturer-sponsored programs. The AG's office can facilitate resolution without the consumer having to use a manufacturer-controlled process. Contact: Missouri AG Consumer Protection Division, (573) 751-3321.

II. VEHICLE INFORMATION

III. WARRANTY INFORMATION

A. Manufacturer's Express Warranty Coverage

All defects arose within the applicable warranty period and were reported within one (1) year of original delivery as required by RSMo § 407.563.

IV. DESCRIPTION OF NONCONFORMITY

A. Primary Nonconformity

The vehicle suffers from the following nonconformity that substantially impairs its use, market value, or safety, as defined under RSMo § 407.560(5):

Summary of Repair Attempts

VI. MISSOURI LEMON LAW QUALIFICATION

A. Statutory Presumption Under RSMo § 407.571

Our Client's vehicle qualifies as a lemon because the statutory presumption of RSMo § 407.571 has been triggered:

☐ Four-Repair Threshold Met (RSMo § 407.571(1)):
The same nonconformity — [________________________________] — has been subject to repair [____] times (≥ 4) without being successfully repaired. The nonconformity continues to exist.

☐ Two-Repair Safety Threshold (RSMo § 407.571 — Life/Safety Defect):
The nonconformity is likely to cause death or serious bodily injury and has been subject to repair [____] times (≥ 2) without success.

☐ 30-Working-Day Threshold Met (RSMo § 407.571(2)):
The vehicle has been out of service for repair for a cumulative total of [____] working days (≥ 30 working days), exclusive of scheduled maintenance downtime.

B. Coverage Period Confirmed

All nonconformities were reported within the applicable coverage period under RSMo § 407.563 (earlier of warranty term or 1 year from delivery):

• First reported nonconformity: [__/__/____]
• Coverage period expiration: [__/__/____]
• Within coverage period: ☐ Yes ☐ No

C. Statute of Limitations Status — RSMo § 407.573

Time is critical. Missouri's 18-month deadline from delivery is among the shorter lemon law statutes of limitations. Do not delay.

D. Federal Magnuson-Moss Warranty Act Claims

In addition to state law claims, our Client has independent claims under the federal Magnuson-Moss Warranty Act, 15 U.S.C. § 2301 et seq. The federal act:

• Applies to written warranties on consumer products sold in interstate commerce
• Provides a private cause of action for breach of warranty
• Awards attorney's fees to prevailing consumers
• Has a 4-year federal statute of limitations under 28 U.S.C. § 1658
• Is not subject to the same arbitration exhaustion requirements as the Missouri state lemon law

Federal Magnuson-Moss claims may be brought in Missouri state court or federal court.

VII. ARBITRATION NOTICE — RSMo § 407.575

Under RSMo § 407.575, if [MANUFACTURER] has established an informal dispute settlement procedure complying with 16 C.F.R. Part 703, our Client must first submit this dispute to that procedure before filing a civil action under Missouri's lemon law.

☐ [MANUFACTURER] sponsors a certified arbitration program. Our Client will submit this matter to [________________________________] arbitration. Our Client reserves all rights if the arbitration result is not acceptable and retains the right to file suit.

☐ [MANUFACTURER] does NOT sponsor a certified arbitration program complying with 16 C.F.R. Part 703. No arbitration exhaustion is required before filing suit in Missouri.

☐ Missouri AG Arbitration Available. Regardless of manufacturer programs, our Client may also utilize the Missouri Attorney General's informal dispute resolution process at (573) 751-3321.

VIII. DEMAND FOR RELIEF — RSMo § 407.565

Pursuant to RSMo § 407.565, we hereby demand the following relief:

A. Primary Relief — Consumer's Election

☐ OPTION 1: FULL REFUND (Repurchase)

Under RSMo § 407.565, the manufacturer must refund the following:

Additionally, [MANUFACTURER] must pay off the outstanding loan/lease balance directly to:
[________________________________] (Lienholder/Lessor), account no. [________________________________]

☐ OPTION 2: REPLACEMENT VEHICLE

Under RSMo § 407.565, the manufacturer must provide a comparable new motor vehicle of the same make, model, year, and specifications as reasonably available, plus reimburse all incidental damages. The replacement vehicle must have a new manufacturer's warranty.

B. Additional Relief in Either Case

1. Incidental Damages: All out-of-pocket costs attributable to the nonconformity, including:
   - Rental car expenses: $[____________________]

X. RESPONSE DEADLINE

Please respond in writing within fourteen (14) days of the date of this letter with:

1. [MANUFACTURER]'s position on whether the vehicle qualifies under RSMo §§ 407.560–407.579;
2. [MANUFACTURER]'s offer for repurchase, replacement, or cure;
3. Scheduling of the final cure attempt, if desired;
4. Identification of any certified arbitration program [MANUFACTURER] requires the consumer to exhaust.

MISSOURI LEMON LAW QUICK REFERENCE — RSMo §§ 407.560–407.579

MISSOURI-SPECIFIC PRACTICE NOTES

☐ Short 18-Month Deadline: Missouri's 18-month statute of limitations from original delivery is shorter than many states (e.g., California provides 4 years). Consumers must act quickly. Count from the date of original delivery to consumer — not from the first repair attempt.

☐ 100,000-Mile Use Formula: Missouri uses 100,000 miles as the use offset denominator (RSMo § 407.567). A vehicle with 5,000 miles at first report = 5% use offset. This formula favors consumers when compared to states using smaller denominators.

☐ Working Days — Not Calendar Days: The 30-day out-of-service threshold is measured in working days, not calendar days. Weekends and holidays do not count toward the 30-day threshold.

☐ Written Notice Is Mandatory: RSMo § 407.563 requires written notice by certified mail before the consumer can seek refund or replacement. This letter satisfies that requirement. Do not proceed to arbitration or litigation without proof of certified mail delivery.

☐ Arbitration Is Not Binding: If the manufacturer requires arbitration under RSMo § 407.575, the consumer is not bound by an unfavorable arbitration outcome. The consumer retains the right to file suit. Arbitration participation merely tolls the statute of limitations (90-day post-arbitration filing window).

☐ Missouri AG as Resource: The Missouri Attorney General's office operates an informal dispute resolution program. Filing a complaint can provide leverage during settlement negotiations even if formal arbitration is not required.

☐ Magnuson-Moss as Backstop: Federal Magnuson-Moss claims (15 U.S.C. § 2301) have a 4-year statute of limitations and do not require exhaustion of a manufacturer's arbitration program. For cases where the Missouri lemon law deadline has been missed, evaluate Magnuson-Moss as an alternative.

☐ Used Vehicles: Missouri's state lemon law covers only new vehicles. Used vehicles may still have Magnuson-Moss Warranty Act claims if a written warranty remains in effect. The Missouri Merchandising Practices Act (RSMo § 407.010 et seq.) may also provide relief for deceptive dealer practices regarding used vehicle sales.
