Infotainment Defects Under Tennessee Lemon Law
Infotainment failures — head-unit lockup, CarPlay disconnects, backup-camera failure — under Tennessee § 55-24-101.
Infotainment defects are increasingly common as vehicle systems become more software-dependent. Tennessee’s Lemon Law (§ 55-24-101) 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 — repeated module failures.
- GM Infotainment 3 (Cadillac CUE) — touchscreen delamination, button failure.
- Audi MMI — system lockup.
- VW MIB2 / MIB3 — Touareg, Atlas (Chattanooga-made), Tiguan issues.
- BMW iDrive — module replacement cycles.
- Subaru Starlink — touchscreen issues, software updates needed.
- Stellantis UConnect 5 — random reboots, CarPlay disconnects.
- Honda Display Audio — Bluetooth issues across models.
- Nissan Smyrna-built models — NissanConnect failures.
Why infotainment defects qualify
- Safety implications — backup camera failure is a federal safety requirement.
- Substantial impairment of market value — infotainment costs $2-5K to replace, flags vehicle history.
- 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.
Special considerations: backup camera
A backup camera that fails is a federal-mandated safety system (FMVSS 111). Failure may also trigger:
- NHTSA recall potential.
- Safety-defect Lemon Law arguments under § 55-24-101 (“substantially impair safety”).
Bottom line
Infotainment defects qualify under § 55-24-101 when they substantially impair use, market value, or safety. Backup-camera failures are particularly strong cases due to federal safety implications.
