My vehicle keeps shutting down while I’m driving. It happened 5 times in the past week and twice today. It happens when I’m driving slow to make a turn or after the car has been stopped for a while (i.g. stop light and drive through window). Three out of five times were in areas where I could safely restart my car. The other two were in the middle of a busy expressway while making a turn and…

What stands out
Of the 19 model years of Hyundai Elantra we track for powertrain problems, this one carries the most owner complaints on file — 60.
Owners have filed 60 powertrain 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.
The failure pattern owners describe
Buyer takeaway: The 2017 Elantra powertrain is plagued by stalling, misfires, and catastrophic engine failures—some owners report metal debris in oil and failed rod bearings despite Hyundai's selective warranty coverage. Be prepared for expensive repairs and safety risks even in the 90k–107k mile range, as recall inclusion varies by VIN.
The 2017 Elantra powertrain cluster reveals widespread, serious failures across multiple systems. Stalling is the dominant complaint—owners report the engine shutting off without warning during turns, deceleration, or idling, sometimes at highway speeds. One owner was stranded pushing a stalled car across three traffic lanes; another barely escaped a roundabout. Loss of power steering and braking accompanies stalls, creating genuine crash risk.
Misfiring on one or more cylinders is frequent and recurring. Owners have replaced ignition coils three to four times in 75,000 miles, with problem returning within months. Check engine lights illuminating codes like P0303 (cylinder 3 misfire) and P0017 (cam/crankshaft position) are common, though some owners get lights with no retrievable codes, leaving dealerships unable to diagnose.
Engine mechanical failure—worn rod bearings, timing chain issues, metal shavings in oil—emerges at 90,000–107,000 miles. Multiple owners describe Hyundai dealerships confirming these are "known issues" with the 2.0L engine, then denying warranty coverage. Engine replacement runs $6,000–$9,000. One owner had a combustion cleaning forced on him ($800) before mechanics found a sheared pin inside the engine that cleaning would never fix.
Transmission jerking, hesitation, and slip-out-of-gear failures plague multiple owners from 200 miles onward. Transmission fluid at 55,000 miles has been reported dirty and filled with metal particles despite being labeled a "lifetime" sealed system.
Unintended acceleration was reported; one catastrophic crash at 25,000 miles occurred when the vehicle lunged and would not brake, with only the driver-side airbag deploying.

Failure modes owners describe
Engine stalling while driving
Engine shuts off abruptly during normal driving, sometimes while turning, decelerating, or after idling. Vehicle must be restarted. Owners report loss of power steering and braking when stalling occurs. Often occurs without warning lights or codes.
When: Various speeds, often during turns or deceleration; reported from 25,000 to 107,000 miles
Symptoms owners cite: Engine shuts off while in motion; Loss of power steering and braking during stall; Check engine light may flash then go out; Vehicle must be manually restarted; Occurs most during turns or deceleration; No warning lights in many instances
Codes mentioned: P0303 (cylinder 3 misfire), P0017 (cam/crankshaft position), P0106 (manifold absolute pressure)
Repairs/costs cited: Dealers have replaced crankshaft position sensors multiple times, reprogrammed PCM via TSB 20-FL-001H, cleared codes; issue recurs. Some owners report $9,000 engine replacement required; others claim metal shavings in oil clog fuel regulation valves.
Recalls/TSBs owners mention: Hyundai extended warranty program exists for some VINs under recall; TSB 20-FL-001H issued for ECM reprogramming. Some owners denied warranty coverage citing sludge buildup or being outside 100k powertrain warranty window.
Engine misfire and rough running
Engine misfires on one or more cylinders, causing jerking, hesitation, vibration at idle and under acceleration. Often accompanied by check engine light and reduced power. Multiple owners replaced ignition coils and spark plugs only to have problem return.
When: Early in ownership (as low as 200 miles) through 95,000 miles; recurring every 3,000-30,000 miles
Symptoms owners cite: Engine jerks and hesitates during acceleration; Rough idling and vibration at stops; Violent shaking at low and high speeds; Reduced power, inability to accelerate; Check engine light illumination; Sputtering, coughing sounds from engine
Codes mentioned: P0303 (cylinder 3 misfire), P0301, P0302, P0304 (cylinder misfires), P0017 (cam/crankshaft)
Repairs/costs cited: Multiple owners replaced ignition coils and spark plugs 3-4 times per owner, usually recurring within months. Dealers have applied TSB 20-FL-001H (ECM reprogramming). Some owners required combustion cleaning ($800) before warranty engine replacement. One owner cited fouled spark plugs from faulty coil packs.
Recalls/TSBs owners mention: TSB 20-FL-001H issued for ECM reprogramming to address misfires. Some warranty denials beyond 100k powertrain coverage; owners outside 60k-5 year window denied coverage despite stated it is common issue.
Engine mechanical failure (rod bearing/timing chain)
Catastrophic internal engine damage including worn/premature rod bearing failure and timing chain looseness, resulting in knocking sounds, loss of power, and complete engine shutdown. Owners report dealerships claim this is known common issue with 2.0L 4-cylinder engine but selectively deny warranty coverage.
When: 93,000 to 107,000 miles; one case at 90,315 miles
Symptoms owners cite: Loud knocking/ticking sound from engine; Engine stalls and will not restart; Metal fragments or shavings found in oil; Loss of motive power while driving; Check engine light; Oil clogging and gallery blockage reported
Codes mentioned: P0017 (cam/crankshaft position)
Repairs/costs cited: Engine replacement required, cost $6,000–$9,000 parts and labor. One owner had combustion cleaning ($800) performed unnecessarily before discovering sheared pin inside engine. Mechanics confirmed metal fragments throughout oil system. One case involved oil debris clogging oil gallery.
Recalls/TSBs owners mention: Selective warranty coverage: some VINs covered under extended warranty despite being same engine and year; others denied. Dealers cite being over powertrain warranty mileage or fault in owner maintenance. Class action lawsuits and recalls referenced by multiple owners but not all VINs included.
Metal debris in oil and engine sludge
Metal shavings, fragments, and sludge accumulate in engine oil, clogging oil galleries and fuel regulation valves. Intermittent stalling results from valve blockage. Problem recurs after oil flush.
When: At 107,000 miles (100k warranty coverage); reported across various mileages; owners at 35,000 and 55,000 miles noted transmission fluid with metal shavings
Symptoms owners cite: Metal shavings or fragments visible in oil; Sludge buildup in engine; Oil clogging fuel regulation valves; Intermittent stalling; Rough running after problem reoccurs; Problem temporarily resolved by oil system flush but returns after ~1 month
Repairs/costs cited: Requires full oil system flush to temporarily clear blockage; problem recurs after approximately one month. One dealership acknowledged manufacturing defect but Hyundai refused to cover. Some owners report oil galleries clogged by small metal parts that broke off internally.
Recalls/TSBs owners mention: Hyundai refused coverage in at least one case despite dealer acknowledgment of manufacturing defect. Some owners cite metal fragments as basis for class action lawsuits and extended warranties, though coverage selective.
Check engine light with no diagnostic codes
Check engine light illuminates but diagnostic scanners cannot pull any trouble codes, making diagnosis and warranty repair impossible. Mechanic unable to reproduce or identify root cause; dealership refuses service without codes.
When: Reported at various mileages; one case at 55,000 miles
Symptoms owners cite: Check engine light illumination; No diagnostic codes retrievable; Dealership refuses to diagnose or service without codes; Lights may be accompanied by stalling, shaking, or electrical issues
Repairs/costs cited: Independent mechanics and dealerships unable to diagnose without codes. Dealership refuses further service (e.g., revokes loaner vehicle) without paying for additional diagnostics like oil change.
Ignition coil failure
One or multiple ignition coils fail, resulting in misfires, rough idle, and engine hesitation. Dealerships acknowledge this as known issue but claim it is not covered under warranty. Owners replacing coils multiple times (3–4+ times in some cases over 30,000 miles).
When: Recurring every 3,000–30,000 miles; one owner replaced coil on cylinder 2 twice in 3,000 miles at 25,000 total miles
Symptoms owners cite: Engine misfire, jerking on acceleration; Rough idle and vibration; Check engine light for cylinder-specific codes; Sputtering, coughing sounds
Codes mentioned: P0301, P0302, P0303, P0304 (cylinder-specific misfires)
Repairs/costs cited: Ignition coil replacement typical repair; some dealerships swap coils between cylinders to isolate fault. One owner replaced coil 3 times in 75,000 miles. Fouled spark plugs sometimes result from faulty coils continuing to fire.
Recalls/TSBs owners mention: Dealership stated ignition coils are 'known for going out' but not covered under warranty. TSB 20-FL-001H issued but does not address ignition coil replacement.
Loss of power / limp mode
Vehicle enters limp mode or loses acceleration capability, stuck in low gear (often 4th gear), with check engine and ESC lights illuminated. RPM and speedometer readings sometimes lost or stuck.
When: Various mileages reported; 10 mph to highway speeds
Symptoms owners cite: Stuck in 4th gear (limp mode); Vehicle cannot accelerate above 40 mph; Loss of RPM and speedometer readings; Check engine and ESC lights illuminated; Shaking and inability to shift properly
Repairs/costs cited: Multiple service visits to dealership with replacements of crankshaft position sensor (three times), PCM, and battery without full resolution. Dealership demanded oil change payment to proceed with further diagnostics despite no visible leaks.
Loss of braking during stall events
When engine stalls, brake pedal becomes stiff and unresponsive, loss of braking assist. Vehicle must coast to stop without driver control.
When: Reported at 10 mph and other speeds
Symptoms owners cite: Brake pedal stiff and unresponsive during stall; Complete loss of braking assist; Vehicle must coast to stop; Loss of power steering also occurs
Repairs/costs cited: Loss of power braking is a consequence of engine shutdown; no repair notes provided beyond stalling root causes.
Transmission jerking and hesitation
Transmission jerks, hesitates, slips out of gear, or does not catch gears properly during acceleration from stop or on inclines. RPM fluctuations occur while holding steady speed. Some owners report grinding noise during gear shifts.
When: Reported from as low as 200 miles; recurring through years of ownership
Symptoms owners cite: Jerking and hesitation during acceleration from stop; Transmission slips out of gear or fails to engage; RPMs jump unexpectedly (2 RPM to 3, 4, 5 RPM); Grinding noise when shifting from park to drive/reverse; Delay in shifting; clunking or rough shifts; Problem worse in Sport mode
Repairs/costs cited: Dual clutch reset attempted at dealership without resolution. Intake manifold cleaning attempted without success. One owner noted transmission is sealed system but fluid at 55,000 miles was dirty and filled with metal particles.
Recalls/TSBs owners mention: Dealership at 200-mile mark stated dual clutch reset was correct repair but failure persisted; dealer kept vehicle 6 days for intake manifold cleaning also without result. Another dealership (Todd Archer Hyundai) stated transmission performing as should when it slipped at 6,000 miles.
Unintended acceleration
Vehicle lunges forward or accelerates spontaneously when shifted to Drive without driver foot on accelerator, or accelerates beyond driver input on flat surfaces. One catastrophic crash reported.
When: Reported from early ownership; one catastrophic crash at 25,000 miles
Symptoms owners cite: Vehicle lunges or accelerates when shifted to Drive without foot on pedal; Spontaneous forward motion on flat surface without accelerator input; Vehicle accelerates beyond driver intent
Repairs/costs cited: Dealership stated lunging is 'typical for Elantra' and not a known issue; suggested may need to 'break in' with parts tightening as wear occurs. Advised holding brake with one foot and accelerator with other to prevent lunge.
Recalls/TSBs owners mention: Dealership denial and blame-the-driver response; 'typical for Elantra' claim and suggestion to break in or use workaround.
Rapid oil consumption
Engine burns through oil at an excessive rate between service intervals, requiring frequent top-ups.
When: Reported at multiple mileages
Symptoms owners cite: Oil level drops rapidly between scheduled oil changes; Low oil warnings
Repairs/costs cited: One owner reported timing belt replacement at 20,000 miles only to have same rapid oil burn issue return; second timing belt replacement was required.
