Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Follow the guidelines outlined in this bulletin to inspect and clean or replace certain components of the engine intake system accordingly during engine short block or sub-assembly replacement.

The failure pattern owners describe
Owners describe three distinct failure patterns with this engine. The first is complete, unpredictable stalling with zero warning—engine simply shuts off at traffic lights, during highway driving, or at idle. RPM and speedometer drop to zero with no check engine light appearing beforehand. Dealers and independent mechanics cannot find a cause; sensors, electrical, and gas systems check out. Restarts happen after 10-20 minutes, but the stalling repeats without pattern.
The second pattern centers on rod bearing failure. Owners hear a small knock that escalates to loud clattering, followed by loss of power and engine seizure. Metal shavings clog oil passages. One owner notes this mirrors the exact failure in recalled 2015-2016 Veloster 1.6L Gamma GDI engines, yet the 2014 Accent with the same engine is not under recall. Even replacement engines suffer the same bearing failure.
Third is oil consumption. Starting around 86,000 to 105,000 miles, engines burn oil rapidly—1 quart every 1,500 miles to 1 quart per week—despite regular service and no leaks. One incident involved engine compartment fire after ABS light activation.
Across all cases, dealership diagnostics and repairs have consistently failed to resolve issues or provide paths forward.

Failure modes owners describe
Complete engine stall without warning
Engine shuts off completely while driving or at idle with no warning lights, check engine light, or symptoms before failure. Vehicle must be restarted after 10-20 minutes. Occurs repeatedly and unpredictably at any speed or condition. Multiple mechanics unable to diagnose root cause; all electrical and sensor checks pass.
When: Between 67,000 and 88,900 miles; multiple incidents within short timeframes
Symptoms owners cite: Complete engine shutdown with no warning; RPM drops to zero; No check engine light or warning signals before stall; Vehicle restarts after 10-20 minutes; Occurs at red lights, while driving, at idle
Codes mentioned: P0335 (crankshaft position sensor DTC)
Repairs/costs cited: One owner replaced crankshaft position sensor (CPS bolt was fractured). Dealership performed induction service but failure recurred immediately. AC condenser replacement also failed to resolve one stall case.
Rod bearing failure and metal shavings
Connecting rod bearings fail prematurely, causing metal shavings to clog the oil passages and restrict oil flow. Begins as a small knock, progresses to loud clattering, loss of engine power, and complete engine seizure. Owners report this is the same issue affecting 2015-2016 Veloster 1.6L Gamma GDI engines under recall, but 2014 Accent with same engine not included in any current recall.
When: Between 100,000 and 155,000 miles; varies by vehicle
Symptoms owners cite: Small knock that escalates to loud clattering from engine; Loss of engine power; Metal shavings clogging oil passages; Engine seizure; Check engine light constantly illuminated
Repairs/costs cited: Complete engine replacement required. One owner quoted $7,000 for engine swap after mechanic identified bad rod bearing. Another owner's replacement engine had identical rod bearing issue despite being from recalled lot (Service Campaign 966).
Recalls/TSBs owners mention: Open Class Action lawsuit to expand recall. Service Campaign 966 exists for affected engines, but dealer refused coverage on swapped engines. Auburn, WA Hyundai dealership failed to respond to owner follow-up after initial contact.
Excessive oil consumption and burning
Engine burns oil rapidly and continuously, requiring frequent top-offs despite regular oil changes and no engine abuse. Issue appears early in vehicle life and worsens over time. No clear leak identified. Burning rate ranges from 1 quart every 1,500 miles to 1 quart per week depending on vehicle.
When: Starting between 86,000 and 105,000 miles; continues through higher mileage
Symptoms owners cite: Burning oil without external leak; Oil pressure warning light flashing; Oil consumption of 1 quart every 1,500 miles to 1 quart per week; Odor reported as 'weird'
Repairs/costs cited: Pep Boys diagnostics could not identify cause or location of oil consumption. Owners advised to check and refill oil regularly. No repair solution provided.
Rough running, misfire on all cylinders, and loss of compression
Check engine light flashes, vehicle runs rough with jerking sensation, and all four cylinders are misfiring. Compression test reveals three cylinders at lower-than-normal PSI and one at 0 PSI, indicating internal engine damage. Spark plug and coil replacement does not resolve the issue.
When: Highway driving at unspecified mileage
Symptoms owners cite: Check engine light flashing; Noticeable decrease in acceleration; Rough running with jerking sensation; Misfire on all 4 cylinders (confirmed by auto parts store)
Codes mentioned: Misfire on all 4 cylinders (inferred from auto parts diagnostic)
Repairs/costs cited: Spark plugs and coil packs replaced; did not correct problem. Certified mechanic compression test showed 3 cylinders below normal, 1 at 0 PSI. Engine replacement recommended.
Recalls/TSBs owners mention: Mechanic noted 'known issues with Hyundai engines' and recommended dealer contact. Owner advised there is an open Class Action lawsuit to expand recall that may include this engine.
Engine stall with AC warning light, RPM drop, and hesitation
While driving at highway speeds or at idle, AC warning light flickers, RPM drops to zero, speedometer drops to zero, and vehicle hesitates as if about to stall. At idle on highway pullover, vehicle stalls completely. Dealership induction service did not resolve issue and failure recurred immediately after service.
When: At 67,000 miles
Symptoms owners cite: AC warning light flickering; RPM dropping to zero; Speedometer dropping to zero; Engine hesitation as if intending to stall; Complete stall when vehicle brought to idle
Repairs/costs cited: Dealership performed induction service; failure reoccurred immediately. Certified mechanic confirmed dealer's findings but vehicle not repaired.
Engine compartment fire
Vehicle suddenly catches fire in engine compartment approximately 45 minutes after parking. ABS warning light had illuminated while driving at 45 MPH shortly before fire. Fire department responded and extinguished flames, but vehicle was completely destroyed.
When: At 115,002 miles
Symptoms owners cite: ABS warning light illumination while driving; Fire in engine compartment; Complete vehicle destruction
Repairs/costs cited: Vehicle completely burned and destroyed on driveway. Not diagnosed or repaired.
Recalls/TSBs owners mention: NHTSA Campaign Number 23V651000 (Service Brakes, Hydraulic) was issued but manufacturer was not notified of this specific fire incident.

After 86,000 miles, the oil consumption per week are 1 quart of gallon. And smell weird
The engine started burning oil at about 105,000 miles, despite it never missing an oil change and never abused. Apparently other Hyundais and Kia’s have also experienced early engine failure due to the manufactures poor quality control. It’ll burn about a quart of oil about every 1,500 miles. The engine has about 127,000 miles on the odometer.
The contact owns a 2014 Hyundai Accent. The contact stated that while driving at highway speeds and when sitting idle the air conditioning warning light would flicker the rpm would drop down or go straight to zero, the speedometer would drop down zero and the vehicle began to have hesitation as if it intends to stall. The contact stated that when the issues occurs on the highway they would pull…
