2018 Hyundai Elantra parts and specs

The Hyundai Elantra is a compact sedan that has spent the last decade and a half undercutting the Civic and Corolla on price while matching them on warranty coverage (Hyundai's 10-year/100,000-mile powertrain warranty follows the original owner). 0L Nu GDI in the sportier Coupe/GT/Sport trims), simple, chain-driven engines with a genuinely different reliability record than the Theta II engines that plagued Sonata/Santa Fe of the same era, though Hyundai still extended engine warranties for a subset of Nu-engine oil-consumption and knock complaints (the 2022 "Hyundai Engine II" class-action settlement). 0L cars whose piston oil rings weren't properly heat-treated.

0L turbo Elantra N hot hatch-turned-sedan (276 hp). Across all three generations the recurring theme for owners is Hyundai's aggressive recall posture, seat belt pretensioners, airbag inflators, an ABS module that could leak brake fluid and short internally (fire risk, recall 23V-651 covering 2011–2015 cars), and steering/brake-booster campaigns on early AD cars, most fixed free at the dealer. Maintenance itself is inexpensive and interval-driven: 5W-20 or 5W-30 oil in the naturally-aspirated engines (0W-20/5W-30 in the turbos and hybrid), a shared spin-on oil filter across nearly the whole lineup, and a CR2032 key fob battery throughout.
