Electrical Defects Under Louisiana Lemon Law / Redhibition

Electrical defects are increasingly common as vehicles become more software-dependent. Louisiana’s Lemon Law (§ 51:1944) covers electrical nonconformities. Hurricane flood electrical damage is a Louisiana Redhibition specialty.

Common electrical failure modes

• Phantom battery drain.
• Body Control Module (BCM) failure.
• Powertrain Control Module (PCM) failure.
• Alternator failure.
• Wiring harness chafing — recall-worthy.
• Headlight / DRL failures.
• Sensor failures — recurring DTCs.
• Multi-system warning lights.

Brand-specific patterns

• Tesla 12V battery — premature failure.
• Ford SYNC / MyFord Touch — module failures.
• Subaru EyeSight — sensor calibration drift.
• Stellantis UConnect — module reset.
• GM CUE / IntelliLink — touchscreen failure.
• Audi MMI / VW MIB — system lockup.
• BMW iDrive — module replacement cycles.

Hurricane flood electrical damage — Redhibition specialty

For Louisiana used vehicles with hurricane flood history, electrical corrosion is the paradigm redhibitory defect:

• Under-seat ECUs corroded by floor flood water.
• Wiring harnesses showing salt deposits / corrosion.
• CAN bus errors from corroded connectors.
• BCM / PCM / TCM failures months after sale.
• Intermittent electrical gremlins — symptomatic of post-flood corrosion.

These cases are paradigm Redhibition + LUTPA cases — particularly when:

• Seller knew of flood history and failed to disclose (bad faith — art. 2545).
• Buyer would not have purchased had they known.

Louisiana climate considerations

• Hot humid summers — connector corrosion (even without flood).
• Coastal salt air — Mississippi River delta corrosion.
• Hurricane wind / rain — moisture intrusion.

Documentation specifics

• All DTC codes captured.
• Parasitic-draw test results if battery drain.
• Module replacement ROs.
• Photos of corrosion patterns — particularly under-seat areas.
• NMVTIS flood title records (if applicable).

Bottom line

Electrical defects qualify under § 51:1944. Hurricane flood electrical damage is a powerful Redhibition + LUTPA case category unique to Louisiana.
