Qualifying Defects: What Counts as a Lemon (or Redhibitory Defect) in Louisiana

Louisiana applies two distinct defect standards — the Lemon Law’s “substantially impair” test and the unique civil-law Redhibition “hidden vice” standard. A defect may qualify under one, both, or neither.

The two defect standards

Lemon Law — “substantially impair” (§ 51:1944)

A “nonconformity” must:

1. Substantially impair the use, market value, or safety of the vehicle.
2. Persist after a reasonable number of repair attempts (4 attempts or 45 days OOS).
3. Be covered under the express manufacturer warranty at the time of the first report.
4. Not be caused by consumer abuse, alteration, or unauthorized modification.

Redhibition — “hidden vice” (La. Civ. Code art. 2520)

A “redhibitory defect” must:

1. Be a vice or defect that renders the thing useless or so diminishes its utility that the buyer would not have purchased it had they known.
2. Have existed at the time of sale (not arisen later).
3. Not be apparent at sale (latent defect).
4. Discovered within prescription period — 1 year from discovery (bad-faith seller) or 4 years from delivery.

Redhibition has no “reasonable attempts” requirement — a hidden vice that materializes is actionable directly, without needing manufacturer repair attempts. This makes Redhibition particularly powerful.

The seven defect categories most often qualifying

1. Transmission — Hard shifts, slipping, fluid leaks, total failure.
2. Engine — Stalling, misfires, excessive oil consumption, knocking, failure.
3. Brakes — Pulsation, dragging, ABS failure, soft pedal, premature wear.
4. Electrical — Battery drain, electrical-system warning lights, module failures.
5. Steering & suspension — Pulling, drift, EPS failure, shock failure, alignment failure.
6. Infotainment — Head unit lockup, Bluetooth/CarPlay failure, backup camera failure.
7. EV-specific — Battery degradation, charging failures, regen brake failures.

Hurricane / flood damage — distinctive Louisiana issue

Louisiana’s history of major hurricanes (Katrina 2005, Ida 2021, Laura 2020) creates a distinctive used-vehicle issue:

• Flood-damaged vehicles sometimes enter the used market without proper disclosure.
• Title-washing across state lines.
• Salt-water / brackish-water corrosion in electrical systems develops over time.

For Louisiana used-vehicle buyers, these are classic Redhibition cases — hidden vice (flood history) that buyer would not have purchased had they known. Plus LUTPA exposure for dealer non-disclosure.

What does NOT typically qualify

• Cosmetic — paint, trim, leather (unless safety-related).
• Tires, batteries, wear items — not covered under express warranty.
• Modifications by consumer or unauthorized installers.
• Damage from accidents — though hurricane flood is a Redhibition issue (not consumer damage).
• Issues outside the 1-year Lemon Law window — but Redhibition’s longer window may apply.

Louisiana climate / geography factors

• Gulf Coast hurricanes — flood damage exposure; salt-water corrosion.
• Hot humid summers — HVAC AC stress, electrical-connector corrosion.
• Brackish coastal air — Mississippi River delta corrosion exposure.
• Mardi Gras / New Orleans tourism — high stop-and-go usage.
• Petrochemical industry fleet — fleet vehicles often have unique use profiles.
