Engine Defects in Florida Lemon Law Cases

Engine defects routinely satisfy Florida’s substantial-impairment test under § 681.102(15). Engines that stall, misfire, consume oil excessively, or fail catastrophically clearly impair use, value, and safety.

Common engine defect categories

Intermittent stalling

Engine cuts out, sometimes at highway speeds. A serious nonconformity that substantially impairs use and safety; once the § 681.104(3) threshold (three attempts, or 30/60 days out of service) is met, it makes a strong claim. Florida has no reduced-attempt safety rule.

Misfires

Rough idle, hesitation under load, check-engine lights. Persistent misfires after multiple repair attempts strongly support a Florida Lemon Law claim.

Excessive oil consumption

Common in Subaru FB-series, Honda 1.5L turbo, BMW N20, and certain other engines. See our Subaru article and Honda article.

Manufacturers often require “oil consumption tests” with multiple measurement visits — each visit counts as a repair attempt.

Head-gasket failures

Coolant in oil, overheating, white smoke. Common in Subaru EJ-series and Hyundai/Kia engines.

Theta II engine failures (Hyundai/Kia)

The 2.0L and 2.4L Theta II engines in 2011-2019 Hyundai Sonata, Santa Fe, Tucson, Kia Optima, Sorento, Sportage have produced widespread Florida cases. See Hyundai and Kia articles.

Timing-chain stretch / failure

BMW N20, Audi 2.0T, Ford EcoBoost, certain Honda V6 applications.

Diagnostic challenges

Engine defects can be hard to reproduce. Strategies:

• Record video of the symptom.
• Note specific conditions.
• Request multi-day diagnostic holds.
• Get diagnostic codes from “no problem found” visits.

Florida-specific considerations

• Stalling cases are strong on substantial impairment, but still require meeting the § 681.104(3) threshold (three attempts, or 30/60 days out of service) — Florida has no reduced-attempt safety rule.
• Oil-consumption cases typically use the three-attempt rule because each measurement visit counts.
• 24-month Lemon Law Rights Period is the timing constraint — file before window closes.

FDUTPA willfulness exposure

Engine cases frequently involve manufacturer TSBs and recalls. Documented manufacturer knowledge supports FDUTPA damages and attorney fees in civil court.

What you should do

1. Pull every repair order.
2. Document oil-consumption test results if applicable.
3. Save any TSBs the dealer mentioned.
4. Check NHTSA recalls for your VIN.
5. Send certified-mail notice.
6. File manufacturer arbitration; talk to a Florida lemon-law attorney about parallel FDUTPA action.
