The 1.8L Nu engine in 2011-2016 Elantras is prone to premature failure due to manufacturing defects including piston ring issues, connecting rod bearing failure, and oil passage problems. Metal debris from failed components can circulate through the engine causing catastrophic da… Repairs typically run $4,000-$7,500. Severity: high.
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.
NHTSA recall 20V061 covers certain 2006-2011 Hyundai Elantra and 2007-2011 Elantra Touring vehicles. Their ABS module remains energized after the vehicle is turned off; if moisture enters its electrical circuit, a short can gradually develop and cause an engine-compartment fire e… 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.
NHTSA recall 23V651 covers certain 2011-2015 Hyundai Elantra vehicles. The ABS module may leak brake fluid internally and develop an electrical short, creating an engine-compartment fire risk while the vehicle is parked or being driven. 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.
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.
MD-generation Elantras with the 1.8L Nu engine develop a distinct two-to-five second rattle or 'diesel' clatter on cold start-up as the hydraulic timing chain tensioner bleeds down overnight and the plastic chain guides wear and become brittle. Early on the noise is only at start… Repairs typically run $700-$1,800. 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.
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 17-ST-002 covers 2007-2010 Elantra, 2009-2012 Elantra Touring and specified-production 2011-2015 Elantra vehicles. The flexible rubber coupling in the motor-driven power-steering assembly may wear and produce a slight clicking or thud noise while the steering wheel is… Severity: low.
MD-generation Elantras have a widely reported failure of the integrated door latch/lock actuator, most often on the driver's door because it cycles the most. The small electric motor inside the latch assembly wears or its gear strips, so the door stops responding to the key fob a… Repairs typically run $200-$600. Severity: low.
