EV-Specific Defects Under Missouri Lemon Law

Electric vehicle (EV) defects present unique Lemon Law issues. Missouri’s growing EV market — Tesla, Rivian, Subaru Solterra, Hyundai Ioniq 5, Kia EV6, Ford Mach-E + Lightning (Claycomo proximity), GM Bolt.

Common EV failure modes

• Battery degradation — premature capacity loss (>20% in 2 years).
• Range loss — particularly in cold weather.
• Charging failures — won’t accept charge, slow charging.
• High-voltage system warnings — repeated faults.
• Regenerative-brake failures — coast mode, blended-brake issues.
• Thermal management failures — battery temperature warnings.
• DC fast-charge failures — Supercharger / EVgo / ChargePoint issues.
• Onboard charger failure — AC charging won’t work.

Brand-specific patterns

• Tesla Model S / X / 3 / Y / Cybertruck — MCU2 eMMC, FSD, charge port, suspension.
• Rivian R1T / R1S — door handle, gear-tunnel issues.
• Lucid Air — charging, MCU.
• Subaru Solterra — range issues, fast-charge speed.
• Hyundai Ioniq 5 / Kona EV — ICCU recall (800V).
• Kia EV6 / Niro EV — same ICCU issues.
• Ford Mustang Mach-E / F-150 Lightning — charging issues, OTA bricking. Lightning is Ford home-state proximate (built at Rouge plant in Michigan, but Ford brand has Claycomo MO ties).
• GM Chevy Bolt EV / EUV — battery recall (LG fires).
• Audi e-tron / Q4 — onboard charger failures.

Missouri EV-specific considerations

• Cold winter range loss — 30-40% range loss typical in Missouri winters.
• Tornado / hail damage — distinguish from defect.
• Charging infrastructure gaps in rural MO — exacerbates range complaints.
• Hot humid summers — battery thermal stress.

Tesla service centers in Missouri

• St. Louis (Brentwood) — primary eastern MO.
• Kansas City (Riverside) — western MO.
• Mobile Service vehicles statewide.

Documentation specifics

• Battery degradation — capacity-test results, range-test data.
• Charging logs — note charger type, session length, end-of-charge SOC.
• Software versions — note firmware before and after each update.
• OTA logs — Tesla’s OTA history.
• DC fast-charging vs. AC charging — separate diagnostics.

Bottom line

EV defects qualify readily under § 407.567. Missouri cold-winter range loss provides distinctive documentary evidence.
