Electrical and Software Defects in Ohio Lemon Law Cases

Electrical and software defects affecting safety equipment, drive systems, or core functionality qualify under Ohio’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 § 1345.72.

Wiring harness failures

Corroded, chafed, or improperly routed harnesses. Ohio winters can 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 CSPA exposure.

ADAS failures

Adaptive cruise, lane departure warning, automated parking.

Infotainment crossing into safety

When failures spill into safety equipment.

Software reflashes as repair attempts

Each reflash counts. Three reflashes meets OH’s three-attempt threshold.

OTA updates

Tesla and others use OTA updates. Trends toward “yes” when targeting a specific defect.

TSBs and CSPA willfulness

When a TSB exists, CSPA “knowing” violation findings produce treble damages.

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 written notice.
5. Get a free case review.
