NHTSA's VIN data lists these trims for the 2010 Sonata. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 345 complaints with NHTSA about the 2010 Sonata. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 2 recall campaigns for the 2010 Sonata over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Hyundai is recalling certain model year 2006-2010 Sonata vehicles manufactured March 1, 2005, through January 21, 2010; and model year 2006-2011 Azera vehicles manufactured September 27, 2005, through November 22, 2010 originally sold in, or currently registered in, Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin and the District of Columbia. Road salt and water can enter portions of the rear crossmember, leading to corrosion of the crossmember steel. This may lead to detachment of one of the rear control arms.
Risk: Control arm separation may suddenly change the rear wheel alignment, affecting the handling of the vehicle, increasing the risk of a crash.
Remedy: Hyundai will notify owners, and dealers will repair or replace the crossmember assembly. The recall began on October 8, 2013. Owners may contact Hyundai Customer Care Center at 1-800-633-5151. Hyundai's recall number is 113.
Hyundai Motor Company (Hyundai) is recalling certain model year 2006-2009 Accent, model year 2007-2011 Azera, Sonata and Sante Fe,2006-2011 Tucson, 2009-2011 Elantra Touring, 2007-2010 Elantra, 2008-2011 Veracruz, 2009-2011 Genesis, 2010-2011 Genesis Coupe, 2007-2008 Entourage, and 2006-2008 Tiburon vehicles. Originally, in April 2013, Hyundai recalled 1,059,824 model year 2007-2009 Accent and Tucson, model year 2007-2010 Elantra, model year 2007-2011 Santa Fe, model year 2008-2009 Veracruz, model year 2010-2011 Genesis Coupe, and model year 2011 Sonata vehicles. In September 2013, Hyundai informed the agency that it was adding more vehicles to this campaign, representing an additional 652,512 units. The total number of vehicles being recalled is now 1,712,336. In the affected vehicles, the stop lamp switch may malfunction. A malfunctioning stop lamp switch may cause the brake lights to not illuminate when the brake pedal is depressed or may cause an inability to deactivate the cruise control by depressing the brake pedal. Additionally, a malfunctioning stop lamp switch may also result in intermittent operation of the push-button start feature, affect the operation of the brake transmission shift interlock feature, preventing the shifter from being moved out of the PARK position and cause the Electronic Stability Control (ESC) malfunction light to illuminate.
Risk: Failure to illuminate the stop lamps during braking or inability to disengage the cruise control could increase the risk of a crash. Additionally, when the ignition is in the 'ON' position, the transmission shifter may be able to be moved out of Park without first applying the brake. This may lead to unintentional movement of the car which may increase the risk of a crash.
Remedy: Hyundai will notify owners, and dealers will replace the stop lamp switch, free of charge. The safety recall began on April 22, 2013. Owners may contact Hyundai at 1-800-633-5151. Hyundai's recall campaign number is 110.
Carmakers sent NHTSA 52 service bulletins and notices that cover the 2010 Sonata, the latest on Oct 8, 2026. They tell dealers how to fix known issues.
The parts they mention most: power train (12), equipment (11), engine and engine cooling (9), electrical system (6), equipment adaptive/mobility (5).
NHTSA defect investigations
Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.
