Electrical and Software Defects Under Colorado Lemon Law

Electrical and software defects are a growing category — particularly with EVs and software-defined vehicles in Colorado’s growing EV market.

Common qualifying electrical defects

12V battery repeated dead.
Alternator failure.
Starter motor failure.
Window / lock failures.
HVAC system electrical failures (critical in Colorado 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 safety issue.
EV firmware bugs affecting range or charging.
Climate-control software failures.

TSB / recall overlay

Software and electrical defects are heavily TSB-driven.

Colorado factors

Cold-weather electrical stress — winter electrical loads stress charging systems.
Altitude electronic-module stress — pressure-sensitive components.
EV cold-weather range degradation — combined with mountain elevation change.

How thresholds apply

Same § 42-10-103 thresholds.

What strengthens an electrical-defect claim

Intermittent symptoms with video documentation.
TSB / OTA update history.
Multiple ECU diagnostic codes.
Pattern across model years (class-action evidence).

What weakens an electrical-defect claim

Aftermarket accessories introducing electrical load.
Driver-installed wiring.
“No problem found” with intermittent symptoms not captured.

Bottom line

Electrical and software defects are well-covered. Document video evidence of intermittent symptoms, secure TSB / recall pattern data.
