Electrical and Software Defects in NC Lemon Law Cases
Modern vehicles are largely software. Electrical/software defects drive a growing share of NC Lemon Law cases.
Electrical and software defects affecting safety equipment, drive systems, or core functionality qualify under NC’s substantial-impairment test.
What counts as an electrical / software defect
Engine and transmission control software
Bad ECU/TCM software causes stalling, poor shifting, “limp mode” triggers. Each reflash counts as a repair attempt under § 20-351.5.
Wiring harness failures
Corroded, chafed, or improperly routed harnesses. NC humidity (especially coastal areas) accelerates corrosion.
Battery management system (BMS) failures
Premature 12V battery failures, “vehicle drained” no-start conditions.
Safety-equipment software bugs
When software defects affect ABS, traction control, stability control — strong UDTPA exposure with mandatory trebling.
ADAS failures
Adaptive cruise, lane departure warning, automated parking, blind-spot monitoring.
Infotainment crossing into safety
When failures spill into safety equipment.
Software reflashes as repair attempts
Each reflash counts. Four reflashes meets NC’s four-attempt threshold.
OTA updates
Tesla and others use OTA updates. NC case law trends toward “yes” when an OTA targets a specific defect.
TSBs and UDTPA mandatory trebling
When a TSB exists, UDTPA violation findings trigger automatic § 75-16 trebling — no willfulness required.
