Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“When there is moisture in the air, my car battery and seat belt warning lights come on. I lose my power steering, my wipers go very slow and a belt starts to squeal. Also, after about 30 minutes, the radio stops working and all indicator lights come on. When it is raining, I am unable to use my defrost or air conditioning as well.”
NHTSA complaint #10979864, filed 2017-04, 146,000 miles“I am reporting this because I see other models with the same engine having the same problem. My valve cover gasket leaked oil onto the alternator and caused it to fail prematurely. This has happened in april of 2014 and has now happened again in june of 2015. Other models utilizing the same engine have been recalled due to this problem. Will this model be recalled?”
NHTSA complaint #10731138, filed 2015-06, 80,000 miles“I have noticed an unusual percentage of Hyundai sonatas with the high visibility brakes lights that do not operate. I checked into having it repaired and the estimate was very expensive. I wondered if this was a manufacturing defect since access to the light is so difficult. I was curious if other complaints had been filed and if anything can be done.”
NHTSA complaint #10442684, filed 2012-01, 30,000 miles“My air bag light has been on for over a year. Come to find out my air bag control module is faulty. An ase certified mechanic gracefully checked my air bag codes for free. This is now putting my life and anyone riding with me in danger seeing as none of my air bags will deploy. According to several forums I've seen, this is not a new problem. Hyundai needs to send out a recall on something that should never fail. My vehicle has never been in a collision.”
NHTSA complaint #11099069, filed 2018-05, 135,000 miles“Valve cover leaks onto alternator, can cause sudden power loss and premature alternator failure. I've been researching this issue and other people have had this exact thing happen. Apparently once you get the valve cover gasket fixed, it will fail again in another year or so. There is a defect either in the gasket or the valve cover mating surface. Currently my car is only at the stage of oil leaking from cover gasket and getting onto the alternator. No further failure has happened yet. My car has 67,000 miles.”
