Electrical and Software Defects Under Minnesota Lemon Law

Electrical and software defects are a growing category. Minnesota’s cold + salt-corrosion climate creates distinctive electrical failure modes.

Common qualifying electrical defects

• 12V battery repeated dead — Minnesota cold accelerates.
• Alternator failure.
• Starter motor failure — cold-start failures particularly common.
• Window / lock failures.
• HVAC system electrical failures (critical in Minnesota winter).
• Headlight / taillight failures.
• Dashboard / cluster failures.

Common qualifying software defects

• OTA update failures bricking systems.
• Infotainment crashes affecting safety systems.
• Driver-assist system failures.
• Phantom braking — categorical 1-attempt safety defect.
• EV firmware bugs affecting range or charging.
• Climate-control software failures (critical in Minnesota).

TSB / recall overlay

Software and electrical defects are heavily TSB-driven.

Minnesota cold + salt factors

• Connector corrosion from road salt.
• Module condensation issues.
• Cold-soak battery failures.
• EV cold-weather range loss.

How thresholds apply

Same § 325F.665 subd. 3(b) thresholds — including 1-attempt for safety-classified electrical/software defects (phantom braking, driver-assist failures, ABS warning).

What strengthens an electrical-defect claim

• Intermittent symptoms with video documentation.
• TSB / OTA update history.
• Multiple ECU diagnostic codes.
• Pattern across model years.
• Safety classification documented where applicable.

What weakens an electrical-defect claim

• Aftermarket accessories.
• Driver-installed wiring.
• “No problem found” without persistent symptom.

Bottom line

Electrical and software defects are well-covered. Phantom braking and driver-assist failures qualify under the 1-attempt safety threshold.
