When driving the car shuts off. The dash lights come on oil battery check engine. Once I stop and put the car in park and restart it it will start right back up. I will die anytime and anywhere. I've been on the highway and it just stops. It does it multiple times before I get to were I need to go. I was almost hit by a semi in traffic doing 40 because it died in the lane

What stands out
Owners have filed 59 engine complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Engine accounts for 23% of all owner complaints filed against this vehicle, across 12 categories tracked.
The failure pattern owners describe
Buyer takeaway: The 2015 Hyundai Elantra shows a pattern of serious engine failures across multiple failure modes—stalling without warning, internal bearing and timing chain damage causing knock and metal shavings in oil, and complete engine seizure—often well before 100,000 miles, even with regular maintenance. Many owners report dealers unable to diagnose the problem or denying coverage; safety is a real concern when these failures occur at speed.
The 2015 Elantra's engine problems cluster around three interconnected failures. Engine stalling is the most dangerous: the car cuts out without warning at any speed, with some owners experiencing 8 stalls in 25 minutes. Loss of power steering and brakes accompanies the stalls, creating collision hazard, especially at highway speeds. Check engine, oil pressure, and battery lights may flash, but not always; some owners find no codes stored at all.
Internal engine damage surfaces as early as 50,000 miles: metal shavings in the oil, bearing and piston failure, timing chain slack, and oil burning (1 quart per 1,000 miles reported). Owners hear escalating ticking, knocking, and grinding that mechanics tie to rod bearing, main bearing, or wrist pin failure. Despite routine oil changes every 3,000–5,000 miles, metal shavings appear, suggesting manufacturing defect in bearing clearances or piston design.
Engine seizure and complete failure end many of these stories. One engine caught fire in the compartment while parked. Dealers and independent shops often cannot replicate the stalling, find no codes, or blame owners for maintenance despite documented service records. Hyundai's response is inconsistent: some warranty claims are approved, but many are denied when mileage exceeds 100,000 or the vehicle is not the original owner. A service campaign exists for P1326 knock detection, but owners report Hyundai continues treating it as an electrical problem rather than addressing the underlying bearing failure.

Failure modes owners describe
Engine stalling / loss of power
Engine cuts out or dies without warning while driving at various speeds (highway, low-speed, idle). Often occurs at intersections or traffic lights. Vehicle loses power steering and brakes when it stalls. Restart typically works, sometimes after multiple attempts.
When: Mileage ranges from 55,000 to 200,000 miles; some reported within weeks or months of ownership
Symptoms owners cite: Engine cuts out without warning; Loss of power steering and brakes; Check engine light, oil pressure light, battery light may flash or illuminate; Dashboard lights flashing; Engine chugging or lurching before stall; High or low idle RPMs; Stalls most common at low speeds or idle, but occurs at all speeds
Codes mentioned: P1326 (Knock Signal error code, indicates engine bearing failure per owner), P0300 (Random misfire), P0301 (Cylinder 1 misfire), P0302 (Cylinder 2 misfire), P0303 (Cylinder 3 misfire)
Repairs/costs cited: Owners cite replacement of crank sensor, timing chain, oil change, throttle body service, fuel pump replacement. Some were told engine replacement needed (~$6,000 used engine cited). Dealers often unable to diagnose when no codes present.
Recalls/TSBs owners mention: Hyundai Service Campaign P1326 Knock Signal error code detection; Some cases denied coverage outside warranty mileage (100k+ miles) or due to salvaged title. Some denied due to perceived maintenance negligence. Class action settlement for transmission slipping affects some 2015 Elantras under 100k miles, but second owners ineligible.
Engine knock, ticking, rattling, grinding noise
Metallic ticking, knocking, grinding, or crackling sounds from engine. Often starts at relatively low mileage (50k–80k) and progressively worsens. Noise occurs at idle, acceleration, or across all RPMs. Metal shavings found in oil, indicating internal bearing or piston damage.
When: Mileage 37,000 to 135,000+; some onset at 50k–80k miles
Symptoms owners cite: Ticking or knocking noise at idle; Noise increases with acceleration; Grinding or crackling sound; Loud, constant knocking from idle through acceleration; Noise between 0–40 mph, settling at higher speeds; Piston slap (lifter knock); Metal shavings visible in oil on dipstick; White smoke from exhaust; Oil consumption (burning oil, e.g., 1 quart per 1,000 miles)
Codes mentioned: P1326 (Knock Signal error, per owner mentioning engine bearing failure), No codes in some cases despite severe noise
Repairs/costs cited: Mechanics diagnosed timing chain failure, wrist pin failure (cylinder 2), rod bearing failure, main bearing failure, crankshaft clearance issues, piston/lifter problems. Engine replacement recommended or performed; cost cited around $6,000 for used engine. Oil changes at 3,000–5,000 mile intervals; metal shavings in oil is key diagnostic sign.
Recalls/TSBs owners mention: Some cases denied coverage beyond warranty (100k miles). One case involved Hyundai Service Campaign bulletin (17V226000) for engine and engine cooling; owner states Hyundai treated P1326 as sensor/electrical issue and replaced components rather than addressing bearing failure. Some warranty replacements approved.
Engine misfire / rough running
Vehicle drives roughly, misfires on random cylinders or specific cylinders, lacks power during acceleration, hesitates on throttle input, or surges RPM without corresponding acceleration.
When: Mileage 53,000 to 179,000 miles
Symptoms owners cite: Check engine light illuminated; Rough driving, jerking; Hesitation or 2–3 second delay when pressing accelerator; Random misfire, particularly after oil changes; Vehicle lacking power during acceleration or merging; Engine revving excessively without acceleration; Timing chain noise ('skipping') or slack; Backfire during acceleration attempt
Codes mentioned: P0300 (Random misfire), P0301 (Cylinder 1 misfire), P0302 (Cylinder 2 misfire), P0303 (Cylinder 3 misfire)
Repairs/costs cited: Mechanics diagnosed timing chain issues, spark plug issues, loose timing chain, oil deposits blocking valves. Repairs included timing chain replacement, spark plug replacement, valve cleaning. One owner reports mechanic said timing chain could snap at any moment.
Recalls/TSBs owners mention: Hyundai Service Campaign (spark plug maintenance noted in one case). Most cases not repaired under warranty; owner responsibility.
Engine fire
Vehicle caught fire while parked outside residence. Fire originated from engine compartment. Vehicle destroyed, no injuries reported.
When: At approximately 100,000 miles
Symptoms owners cite: Fire in engine compartment while parked; No prior warning signs
Repairs/costs cited: Vehicle was destroyed. Not repaired.
Recalls/TSBs owners mention: No manufacturer response documented. Owner cited fire risk acknowledged in recall documentation.
Oil consumption / low oil with no warning
Engine consumes oil between service intervals despite proper oil changes. Low oil warning light may not illuminate even when oil level is critically low. One case involved bulging oil filter gasket; another involved faulty engine warping oil filter.
When: Various mileages; one case at 180,000 miles noted 1 quart per 1,000 miles burn rate
Symptoms owners cite: Oil level drops rapidly between changes; Low oil warning light does not illuminate despite low levels; Oil requiring manual checking and topping; Bulging oil filter gasket (one case; Firestone oil change); Hyundai inspected and blamed oil change facility; Firestone inspection showed Hyundai engine warped filter due to engine defect
Repairs/costs cited: One owner topped off oil; Firestone completed inspection showing engine fault. Oil burning tied to internal damage (piston/bearing failure).
Recalls/TSBs owners mention: One case: Hyundai dealership blamed third-party oil change; Firestone found Hyundai engine defect. No warranty coverage offered in consumption-only cases.
Engine seizure / failure to restart
Engine seizes or fails to restart after normal operation. No warning indicators before seizure. Engine may make loud knocking after seizure attempts.
When: Mileage 58,000 to 130,000 miles
Symptoms owners cite: Engine fails to start after normal operation; Engine seized, non-drivable; Loud knocking after attempted restart; No warning lights prior to failure; Oil check reveals metal shavings
Repairs/costs cited: Engine replacement required; one owner paid ~$6,000 for used engine. Repair shops confirmed engine dead/seized.
Recalls/TSBs owners mention: Owner reported out-of-warranty mileage (127,000 miles); Hyundai denied assistance. Another case at 130,000 miles with salvaged title also denied by Hyundai.
Blown head gasket
Head gasket failure occurred at relatively low mileage during acceleration/merging onto highway.
When: 62,000 km (approximately 38,500 miles)
Symptoms owners cite: Engine backfired during acceleration attempt; Blown head gasket
Repairs/costs cited: Owner changed oil every 8,500 km as prescribed.
Recalls/TSBs owners mention: Hyundai debated warranty coverage despite owner following maintenance schedule.
