Electrical Defects Under Indiana Lemon Law

Electrical defects are increasingly common as vehicles become more software-dependent. Indiana’s Lemon Law (§ 24-5-13) covers electrical nonconformities that substantially impair use, market value, or safety.

Common electrical failure modes

• Phantom battery drain — battery dies overnight from parasitic load.
• Body Control Module (BCM) failure.
• Powertrain Control Module (PCM) failure.
• Alternator failure — premature.
• Wiring harness chafing — recall-worthy.
• Headlight / DRL failures.
• Sensor failures — recurring DTCs without root cause.
• Multi-system warning lights — dashboard light show on startup.

Brand-specific patterns

• Tesla 12V battery — premature failure across all models.
• Ford SYNC / MyFord Touch — module failures.
• Subaru EyeSight (SIA Lafayette) — sensor calibration drift.
• Stellantis UConnect — module reset, audio failure.
• GM CUE / IntelliLink — touchscreen failure.
• Audi MMI / VW MIB — system lockup.
• BMW iDrive — module replacement cycles.
• Honda Civic / CR-V (Greensburg) — Bluetooth, infotainment issues.

Why electrical defects qualify

1. Cumulative attempts — diagnosing electrical issues often takes 4+ visits.
2. Safety implications — many systems are safety-critical (ABS, airbag, traction control).
3. Market value impairment — electrical issues plague resale value.

Indiana climate considerations

• Cold winter starts — northern IN battery / alternator stress.
• Lake-effect snow + salt — connector corrosion in N. Indiana.
• Summer humidity + thunderstorms — moisture intrusion, lightning surge concerns.
• Tornado season — distinguishing weather damage from defect.

Documentation specifics

• All DTC codes captured — even “transient” or “history” codes.
• Parasitic-draw test results if battery drain.
• Module replacement ROs.
• Software-update logs — TCM / PCM / BCM reprograms.
• Recall documentation.

Bottom line

Electrical defects qualify under § 24-5-13 when they substantially impair use, market value, or safety. Document every diagnostic visit, every code, every software update.
