Electrical and Software Defects in NJ Lemon Law Cases

Modern vehicles are largely software. Electrical/software defects drive a growing share of NJ Lemon Law cases.

Electrical and software defects affecting safety equipment, drive systems, or core functionality qualify under NJ’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 § 56:12-33.

Wiring harness failures

Corroded, chafed, or improperly routed harnesses. NJ road salt and humidity accelerate 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 CFA exposure with mandatory § 56:8-19 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. Three reflashes meets NJ’s three-attempt threshold.

OTA updates

Tesla and others use OTA updates. NJ case law trends toward “yes” when an OTA targets a specific defect.

TSBs and CFA mandatory trebling

When a TSB exists, CFA violation findings trigger automatic § 56:8-19 trebling — no willfulness required.

What you should do

  1. Document each repair attempt — dealer visits AND OTA updates.
  2. Note specific trigger conditions.
  3. Save dash-cam or smartphone video.
  4. Send certified-mail notice.
  5. Get a free case review.
