Are Used Vehicles Covered Under Missouri Lemon Law?

No — Missouri’s Lemon Law (§ 407.560) does NOT cover used vehicles. Missouri relies on Magnuson-Moss + MMPA + UCC for used-vehicle defect cases.

What used vehicle buyers can rely on

Magnuson-Moss Warranty Act — applies where factory or dealer warranty is in place. 4-year UCC SOL.
MMPA (§ 407.010 et seq.) — applies to deceptive used-car practices. 5-year SOL, post-SB 591 pleading required.
UCC § 400.2-313 / § 400.2-314 — express and implied warranties. 4-year SOL.
Common-law fraud — for willful concealment.

MMPA for used-vehicle deceptive practices (post-SB 591)

MMPA covers:

Misrepresentation of vehicle condition.
Failure to disclose salvage, prior accidents, odometer rollback.
Deceptive warranty representations.
F&I deceptive add-ons.

Punitive damages + mandatory § 407.025(1) fees + 5-year SOL. Post-SB 591 ascertainable loss specificity required.

”As-is” sales

Missouri permits “as-is” used-vehicle sales — typically with disclaimer in the buyer’s guide.

Practical advice for used-car buyers

Get pre-sale inspection by independent mechanic.
Check Carfax / AutoCheck for prior damage.
Confirm warranty in writing.
Save the buyer’s guide required by FTC.
Document any defects immediately.
Document ascertainable loss for MMPA pleading.

Bottom line

Missouri’s Lemon Law doesn’t cover used vehicles. Used-car claims rely on Magnuson-Moss + MMPA + UCC. MMPA’s 5-year SOL provides solid runway.
