Hyundai Lemon Law Cases in Florida

Hyundai vehicles are a substantial share of Florida Lemon Law caseload, driven primarily by Theta II engine failures and a string of significant recalls. Hyundai shares platforms with sister brand Kia.

Common Hyundai defect categories

Theta II engine failures

The Theta II 2.0L and 2.4L 4-cylinder engines (2011-2019 Sonata, Santa Fe, Tucson) are one of the most-litigated engine failures in Florida Lemon Law history. Knocking noises, sudden engine failure, connecting rod bearing failures, sudden loss of power on the highway.

Hyundai issued multiple recalls and extended warranties. Affected Florida buyers brought Florida Lemon Law claims plus FDUTPA actions, often with substantial damages given documented manufacturer awareness.

Knock Sensor Detection System (KSDS) interactions

KSDS triggering at low mileage often produced repeated repair visits without resolving the underlying issue — meeting the three-attempt threshold.

Transmission issues

• 8-speed automatic in Sonata, Santa Fe, Palisade.
• DCT in Veloster N, Elantra N.
• CVT in certain hybrids.

See transmission defects article.

Hyundai’s customer-relations and settlement profile
