2018 Hyundai Elantra: True Cost, Problems & Verdict
282 NHTSA owner complaints · 0 recalls · data-computed verdict. No opinions — public data only.
Editor's note
The fifth-generation Elantra (2011–2016) carries complaints about the engine's piston-slap ticking, premature brake wear, and — with the highest counts — steering that pulls and wanders, which Hyundai addressed with a software update to the electric power steering. The 2011–2013 years are the worst of it; 2014–2016 score above 78. Read the full note on the model page. 2018 specifically: a year the record favours — 282 complaints, score 81/100. The caveats in the note apply to other years of this nameplate more than to this one.
