Infotainment Defects Under Missouri Lemon Law

Infotainment defects are increasingly common as vehicle systems become more software-dependent. Missouri’s Lemon Law (§ 407.567) covers infotainment nonconformities when they substantially impair use, market value, or safety (including backup-camera safety functions).

Common infotainment failure modes

• Head-unit lockup / freeze — touchscreen unresponsive.
• Random reboots — system reboots while driving.
• Bluetooth / CarPlay / Android Auto disconnects — repeated.
• Backup camera failure — federally required safety feature.
• Navigation lockup — incorrect routing, frozen maps.
• Audio system failure — speakers cut out, distortion.
• Voice recognition failure — system unresponsive.

Brand-specific patterns

• Tesla MCU2 eMMC failure — touchscreen failure on early Model S/X (recall).
• Ford SYNC 3 / SYNC 4 (Claycomo F-150) — repeated module failures. MO home-state pattern.
• GM Infotainment 3 (Cadillac CUE) — touchscreen delamination.
• Audi MMI — system lockup.
• VW MIB2 / MIB3 — system lockup.
• BMW iDrive — module replacement cycles.
• Subaru Starlink — touchscreen issues.
• Stellantis UConnect 5 — random reboots, CarPlay disconnects.
• Honda Display Audio — Bluetooth issues across models.
• Toyota Entune / Audio Multimedia — touchscreen, CarPlay.

Why infotainment defects qualify

1. Safety implications — backup camera failure is a federal safety requirement.
2. Substantial impairment of market value — infotainment costs $2-5K to replace.
3. Cumulative attempts — typically requires multiple software updates or module replacements.

Documentation specifics

• Specific failure conditions — cold start, hot start, post-update, etc.
• Software version at each visit — record before/after updates.
• Module replacement ROs.
• CarPlay/Android Auto compatibility — note phone model and OS version.

Bottom line

Infotainment defects qualify under § 407.567 when they substantially impair use, market value, or safety. Backup-camera failures are particularly strong cases due to federal safety implications.
