What is the 2011-2015 Hyundai Elantra ABS Module Electrical Short and Fire Risk?

The Anti-Lock Brake System (ABS) module may leak brake fluid internally causing an electrical short, which can result in an engine compartment fire while parked or driving. This is a critical safety recall. Owners are advised to park outside and away from structures until recall… Repairs typically run $0-$0. Severity: high.

What is the 2007-2013 Hyundai Elantra Airbag Sensor and Control Module Malfunction?

Multiple airbag-related recalls affect Elantras due to driver seat track position sensor issues and passenger weight sensor contamination. The driver's airbag may deploy at incorrect pressure, and the passenger airbag may deploy regardless of occupant weight. Nearly 285,000 vehic… Repairs typically run $0-$500. Severity: high.

What is the 2006-2011 Hyundai Elantra ABS Module Short Circuit Causing Engine Compartment Fire (Recall 20V061)?

The anti-lock brake (ABS) hydraulic control module stays electrically energized even after the car is shut off. Over time, moisture can intrude into the module's circuit board and create a slowly developing electrical short. Because the circuit is live with the key off, the short… Repairs typically run $0-$0. Severity: high.

What is the 2011-2017 Hyundai Elantra Crankshaft Position Sensor Failure Causing Stalling?

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.

What is the 2011-2018 Hyundai Elantra Panoramic Sunroof Spontaneous Shattering?

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.

What is the 2011-2016 Hyundai Elantra MDPS Rubber Coupler Wear — Steering Clunk / Knock and Loss of Assist?

The Motor Driven Power Steering (MDPS) unit uses a flexible rubber coupling between the assist motor and the steering column. The rubber isolator wears, cracks, or develops play, producing a distinct clicking, clunking, or thud through the wheel during low-speed turns and on roug… Repairs typically run $80-$1,300. Severity: medium.

What is the 2009-2020 Hyundai Elantra P0011 — Intake Camshaft Timing Over-Advanced (Bank 1) from Stuck CVVT Oil Control Valve?

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.

What is the 2007-2020 Hyundai Elantra P0171 — System Too Lean (Bank 1) from Vacuum Leak / Dirty MAF?

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.

What is the 2011-2022 Hyundai Elantra P0420 — Catalyst Efficiency Below Threshold (Bank 1), Often Downstream of Nu 2.0L Oil Consumption?

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.

What is the 2011-2020 Hyundai Elantra P0128 — Coolant Below Thermostat Regulating Temp from Stuck-Open Thermostat?

P0128 sets when the Elantra's engine fails to reach its expected operating temperature within the calibrated time, which the PCM interprets as a thermostat that is stuck partially open (letting coolant circulate too early). This is a known enough pattern on 2017 Elantras that Hyu… Repairs typically run $150-$411. Severity: low.
