Known issues for this generation
Owner complaints for early years in this span (especially 2013) concentrate on the engine. Safety recall 17V-226 covers certain 2013-2014 Sonata and Santa Fe Sport vehicles: machining errors during engine manufacturing may cause premature bearing wear that can seize the engine; dealers inspect and replace the short block as needed. Safety recall 22V-312 (replacing 20V-121) covers certain 2013-2014 Sonatas whose low-pressure fuel hose between the low-pressure and direct-injection pumps may crack from engine-bay heat and leak fuel; dealers replace that hose. Safety recall 18V-934 covers certain 2011-2014 Sonatas previously remedied under 15V-568 or 17V-226 whose high-pressure fuel pipe may have been damaged or mis-torqued during engine replacement and can leak; dealers inspect and replace the pipe as needed. Safety recall 16V-956 covers a small build of 2017 Sonatas (and Elantras) whose driver frontal air-bag inflator end seal may be missing; dealers replace the driver frontal air-bag module.
