The 2010 Hyundai Sonata carries 2 open NHTSA recalls — most recently covering switch and rear. Owners report 7 recurring issue clusters, led by “Exterior door handle breakage.” Hyundai's owner's manual splits service into Normal and Severe schedules. Most US drivers qualify as Severe due to short trips, extreme temperatures, or stop-and-go traffic. Hyundai Assurance covers the first 3 years / 36,000 miles of complimentary maintenance on new vehicles. The Theta II 2.0L and 2.4L engines (2011-2019) are subject to TSBs around oil consumption — strict adherence to oil intervals matters.

Campaign #13V113000 · Jan 4, 2013
Issue: 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.
Fix: 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.
SUSPENSION:REAR
Campaign #13V354000 · Dec 8, 2013
Issue: 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.
Fix: 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.

Critical for safety and preventing major damage
Severe service: every 3,750 miles. Normal service: 7,500 miles. Theta II 2.0L/2.4L (Sonata, Santa Fe, Tucson 2011-2019): never extend — oil consumption issues are documented in Hyundai TSBs.
Estimated cost — typical U.S. ranges
Dealer
~$120–$160
Shop
~$85–$115
DIY
~$25–$55
Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.
Rotate tires every 7,500 miles. AWD Tucson and Santa Fe owners benefit from rotation at 5,000 miles.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop

DIY
Free
Often free at the shop where you bought the tires — worth asking before paying.
Inspect brake pads, rotors, calipers, and parking brake every 7,500 miles. Elantra and Sonata front pads typically last 40,000-50,000 miles.
Estimated cost — typical U.S. ranges

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.
Replace DOT 3 brake fluid every 30,000 miles or 24 months. Required to maintain ABS and ESC pump life.
Estimated cost — typical U.S. ranges
Dealer
~$180–$200
Shop
~$125–$140
DIY
~$10–$25
DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.
Keeps your vehicle running smoothly and efficiently

Estimated cost — typical U.S. ranges
Dealer

5-minute job on most cars; the airbox lid usually has clips, no tools needed.

Estimated cost — typical U.S. ranges
Dealer
~$330–$500
Shop
~$235–$355
DIY
~$60–$180
Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.

Hyundai Long-Life Coolant (pink): first change at 60,000 miles, then every 30,000. Do not substitute green or orange coolant — it damages the cylinder head gasket on GDI engines.
Estimated cost — typical U.S. ranges
Dealer
~$285–$330
Shop
~$200–$235
DIY
~$25–$60
Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.
