Qualifying Defects: What Counts as a Lemon in Connecticut

Defect categories that meet Connecticut's 'substantially impair the use, value, or safety' test under § 42-179.

Connecticut’s Lemon Law (§ 42-179(d)) covers any “nonconformity” — a defect or condition that substantially impairs the use, value, or safety of the vehicle and is not the result of consumer abuse.

The “substantially impair” test

Under § 42-179(d), a “nonconformity” must:

  1. Substantially impair the use, value, or safety of the vehicle.
  2. Persist after a reasonable number of repair attempts (4 attempts or 30 days OOS).
  3. Be covered under the express manufacturer warranty at the time of the first report.
  4. Not be caused by consumer abuse, alteration, or unauthorized modification.

The seven defect categories most often qualifying

  1. Transmission — Hard shifts, slipping, fluid leaks, total failure.
  2. Engine — Stalling, misfires, excessive oil consumption, knocking, failure.
  3. Brakes — Pulsation, dragging, ABS failure, soft pedal, premature wear.
  4. Electrical — Battery drain, electrical-system warning lights, module failures.
  5. Steering & suspension — Pulling, drift, EPS failure, shock failure, alignment failure.
  6. Infotainment — Head unit lockup, Bluetooth/CarPlay failure, backup camera failure.
  7. EV-specific — Battery degradation, charging failures, regen brake failures.

What does NOT typically qualify

  • Cosmetic — paint, trim, leather (unless safety-related).
  • Tires, batteries, wear items — not covered under express warranty.
  • Modifications by consumer or unauthorized installers.
  • Damage from accidents or environmental (flood, hail).
  • Issues outside the 2-year / 24,000-mile Rights Period that aren’t documented in the Period.

Connecticut climate factors

  • Sub-zero New England winters — battery, ignition, fluid viscosity issues.
  • Heavy road salt — corrosion, brake-line failure, electrical-connector corrosion.
  • Coastal salt air (Long Island Sound) — corrosion exposure for cars in Bridgeport, New Haven, Stamford, New London.
  • Stop-and-go I-95 corridor — transmission and brake stress.
