The electronic power steering (EPS) system fails due to a rubber star damper gear inside the steering column that deteriorates. This causes steering play of up to one inch before wheels respond, making the vehicle difficult to control. Over 200,000 vehicles were recalled for torq… Repairs typically run $800-$3,200. Severity: high.
Hyundai identifies certain 2011-2022 Elantra vehicles with traditional turn-key ignitions and without engine immobilizers as affected by theft methods that bypass the vehicles' security features. Vehicles with push-button start or an immobilizer indicator are not in this software… Severity: high.
P0016 means the intake camshaft position no longer correlates with the crankshaft position within the allowed window. On the Elantra's CVVT engines the two dominant causes are (1) a clogged/stuck Oil Control Valve (OCV/CVVT solenoid) — its internal screen loads up with sludge fro… Repairs typically run $150-$1,300. Severity: high.
The crankshaft position sensor fails, causing intermittent stalling, hard starting, and no-start conditions. The problem often worsens when the engine is hot and may not trigger check engine codes initially. Sensor harness corrosion is a common contributing factor. Repairs typically run $150-$400. Severity: medium.
Panoramic sunroofs in Hyundai Elantras have spontaneously shattered while driving, often described as sounding like a gunshot. Broken glass falls into the cabin, creating safety hazards. A class action settlement provided an extended 10-year/120,000-mile warranty for shattered su… Repairs typically run $800-$1,500. Severity: medium.
Hyundai TSB 21-AT-013H covers certain 2017-2018 Elantra Sport 1.6L Turbo and Elantra 1.4L Turbo vehicles equipped with the 7-speed dual-clutch transmission. The bulletin states that these vehicles may exhibit abnormal vibration at low speeds and provides a GDS clutch-judder inspe… Severity: medium.
P0011 sets when the intake camshaft is more advanced than the PCM commanded (or the CVVT system won't respond correctly). On the Elantra this is most often a stuck/clogged intake Oil Control Valve (CVVT solenoid): the valve's fine internal screen plugs with oil varnish/sludge, so… Repairs typically run $120-$400. Severity: medium.
Elantras run in road-salt regions suffer a consistent rear brake problem: the rear caliper piston and the caliper slide pins corrode and stop retracting, so the pads stay in light contact with the rotor. The tell-tale is rear pads wearing out faster than fronts - the reverse of t… Repairs typically run $250-$900. Severity: medium.
The Elantra Sport's 1.6L Gamma T-GDI is a direct-injection-only engine: no fuel ever washes across the back of the intake valves, so oil vapour drawn in through the PCV system bakes onto the valve stems and seats. Owners on the Elantra Sport community report visible deposits by r… Repairs typically run $450-$1,200. Severity: medium.
Elantras fitted with a sunroof route water that gets past the glass seal into four corner drains and down tubes inside the A-pillars and rear pillars. On cars parked under trees the corner drains silt up with pollen, leaf debris and dirt, and the tubes themselves can pull off the… Repairs typically run $0-$600. Severity: medium.
On the Elantra's inline-4 (Beta II 2.0L in 2007-2010, Nu 2.0L in 2011+), P0171 means fuel trims have gone too positive because unmetered air is entering the engine. The classic Elantra trigger is a vacuum leak — most often a hardened/cracked PCV hose or a leaking intake-manifold… Repairs typically run $50-$450. Severity: medium.
P0420 on the Elantra means the downstream (post-cat) oxygen sensor sees the catalytic converter no longer scrubbing efficiently. On the 2017-2020 Nu 2.0L engine this frequently is not just an aged cat — it is a symptom of the well-documented Nu 2.0L piston-ring/oil-consumption de… Repairs typically run $300-$1,800. Severity: medium.
Hyundai TSB 26-BD-002H covers certain 2015-2016 Elantra UD and 2017-2018 HMMA-built Elantra ADa vehicles finished in Quartz White Pearl paint code W8 or WW8. White paint may peel or bubble on metal body panels including the hood, fenders, roof, doors, quarter panels and trunk. Pl… Severity: low.
Hyundai TSB 18-01-012 covers certain 2017 Elantra AD/ADa vehicles with the 2.0L Nu MPI engine. The thermostat may not function properly and may set DTC P0128. Hyundai states that no drivability issues are associated with this campaign condition. Severity: low.
