The 2014 Elantra is a mixed bag — the 1.8L/2.0L Nu engines suffer catastrophic bearing failures and piston seizures due to manufacturing defects, while transmissions leak internally and mount failures are epidemic. When they run, they're fine; the question is *if* they'll survive to 100k.
Catastrophic Engine Bearing Failure (Nu Engine Defect)
Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Sudden metallic knocking from bottom end, often with no warning, Complete seizure — engine stops running mid-drive, Metal shavings in oil, scored crankshaft journals, Rod thrown through block in severe cases
Fix: Total engine replacement or complete rebuild. Hyundai extended warranty covers some cases under settlement, but many fall outside. If self-pay: 18-25 hours labor for used engine swap, 35-50 hours for full rebuild with machine work.
Estimated cost: $4,500-8,500
Transmission Oil Cooler Internal Leak
Common · high severity
Typical onset: 70,000-110,000 mi
Symptoms: Transmission slipping, delayed engagement, or hard shifts, Coolant mixing with ATF — strawberry milkshake color in reservoir or trans pan, Engine overheating if enough coolant enters transmission, Transmission failure if coolant contaminates clutch packs
Fix: Replace transmission oil cooler assembly inside radiator, flush both cooling and transmission systems. If contamination severe, transmission rebuild required. 4-6 hours for cooler/flush, add 12-18 hours if trans needs internal work.
Estimated cost: $1,200-2,800
Transmission Mount Failure (Front Right)
Common · medium severity
Typical onset: 50,000-90,000 mi
Symptoms: Excessive engine rocking when shifting from Park to Drive, Clunk or thud on acceleration or deceleration, Vibration through cabin at idle or under load, Visible tearing or separation of rubber isolator
Fix: Replace front right transmission mount. Access is tight but straightforward. OE mounts fail prematurely; aftermarket options often firmer but last longer. 1.5-2 hours labor.
Estimated cost: $180-350
ABS Control Module Failure (Recall-Related)
Occasional · high severity
Symptoms: ABS and ESC warning lights on dash, Loss of anti-lock braking function, In rare cases: unintended braking or brake drag, Module corrosion from water intrusion
Fix: NHTSA recall 14V-576 addresses this — check VIN for open recalls. If not covered, module replacement requires programming. 2-3 hours labor if not warranty.
Estimated cost: $800-1,400
Fuel Pump Failure (In-Tank)
Occasional · high severity
Typical onset: 80,000-130,000 mi
Symptoms: No-start condition with full tank, Stalling at highway speeds or under load, Intermittent rough running or surging, Whining noise from rear seat area (pump straining)
Fix: Replace fuel pump assembly in tank. Tank must be dropped on sedan (coupe access via rear seat). 3-4 hours labor. OE pumps preferred — aftermarket often fail prematurely.
Estimated cost: $650-1,100
Brake Pedal Stopper Pad Detachment
Occasional · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Brake lights stay on continuously, Cannot shift out of Park (interlock engaged), Pedal travel feels slightly longer than normal, Small rubber pad found on floor
Fix: Recall 15V-568 covers many cases. Replace brake pedal stopper pad — it's a $5 part but requires dealer-specific adhesive primer. 0.3 hours labor if DIY, 0.8 hours at shop for proper procedure.
Estimated cost: $45-120
Owner tips
Check engine oil level EVERY fillup — Nu engines burn oil and low level accelerates bearing failure.
Verify all recall work completed via NHTSA VIN lookup before purchase.
Inspect coolant and ATF regularly for cross-contamination (milky appearance).
Consider extended engine warranty if purchasing used under 100k miles — bearing failures strike without warning.
Change transmission fluid every 40k miles regardless of 'lifetime fill' claim — helps prolong cooler life.
Hard pass unless engine replacement already documented or you're getting it cheap enough to budget for one — the Nu engine is a ticking time bomb.

Hyundai Motor America (Hyundai) is recalling certain 2011-2015 Elantra, Genesis Coupe, Sonata Hybrid, 2012-2015 Accent, Azera, Veloster, 2013-2015 Elantra Coupe, Santa Fe, 2014-2015 Equus, 2010-2012 Veracruz, 2010-2013 Tucson, 2015 Tucson Fuel Cell, and 2013 Santa Fe Sport vehicles. The Anti-Lock Brake System (ABS) module may leak brake fluid internally and cause an electrical short, which can result in an engine compartment fire while parked or driving.
Consequence: An engine compartment fire while parked or driving can increase the risk of injury.
Remedy: Owners are advised to park outside and away from structures until the recall repair is complete. Dealers will replace the ABS fuse, free of charge. Owner notification letters were mailed April 10, 2024 through October 11, 2024. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 251.
SERVICE BRAKES, HYDRAULIC:PEDALS AND LINKAGES · 17V769000
2017-11-30
Hyundai Motor Company (Hyundai) is recalling certain 2013-2014 Elantra sedan, coupe and GT vehicles. The brake pedal stopper pad can deteriorate allowing the brake light switch plunger to remain extended when the brake pedal is released. This will allow the brake lights to remain illuminated continuously. It can also allow the shift lever to be moved without depressing the brake pedal, or activate the engine management brake pedal override feature.
Consequence: If the brake light switch plunger does not retract as it should when the brake pedal is not being pressed, the brake lights may stay illuminated preventing accurate communication to following vehicles that the vehicle is slowing or stopping. Additionally, if the brake switch plunger is not retracted, then the transmission can be shifted out of PARK without depressing the brake pedal. Either condition increases the risk of a crash.
Remedy: Hyundai will notify owners, and dealers will replace the brake pedal stopper pad, free of charge. The recall is expected to begin February 8, 2018. Owners may contact Hyundai customer service at 1-800-633-5151. Hyundai's number for this recall is 170. This campaign expands recall 16V574.
