Hyundai Motor America (Hyundai) is recalling certain 2011-2014 Sonata and 2013-2014 Santa Fe Sport vehicles previously repaired under recall numbers 15V-568 and 17V-226.

Maintenance & Warranty
Recommended Hyundai SONATA Service Intervals
Turbo engines (1.6T, 2.0T) need premium fuel and more frequent oil (some owners service at 5,000 miles).
"Severe service" conditions (heavy towing, extreme temps, city stop-and-go) typically halve these intervals. Always consult your vehicle's owner's manual for the authoritative schedule.
Hyundai New-Vehicle Warranty Coverage
10 years/100K powertrain warranty is transferable only to first purchaser after initial owner
These are the terms for a new Hyundai. If you're buying a used 2012 SONATA, remaining coverage is usually pro-rated from the vehicle's original in-service date. Not all coverage transfers between owners — check with a Hyundai dealer for VIN-specific remaining warranty.
Estimated Repair Costs
