What stands out
Owners have filed 34 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 27% of all owner complaints filed against this vehicle, across 7 categories tracked.
The failure pattern owners describe
Buyer takeaway: The 2011 Tucson's 2.4L Theta-II engine has a chronic oil pan seal leak (recall 19V063000) that can lead to complete oil loss, stalling, and catastrophic engine failure even after repair attempts. Multiple owners faced months-long parts shortages, surprise engine replacement bills over $6,000, and some denials due to warranty expiration—even when the vehicle was within recall mileage ranges.
This engine fails in two ways: slow and fast. The slow way is an oil pan seal leak that starts as seepage, triggers intermittent oil warning lights, and gradually starves the engine of oil until internal components fail. Owners describe knocking and ticking noises that persist even after oil top-offs, then suddenly the car dies on the highway with no restart. Fast failures happen without warning—the engine just shuts down mid-drive.
Hyundai issued recall 19V063000 in February 2019 for exactly this oil pan seal problem on 2010–2013 Tucsons with 2.4L engines, but the remedy parts didn't ship to dealerships for months. Owners with recall notices were told to wait; some waited six months or more with no update. When engines failed while parts were still unavailable, Hyundai denied coverage, citing warranty expiration or sludge buildup from neglect—even at 79,000–123,000 miles.
In several cases, engine replacement was the only option, costing owners $6,000 or more out of pocket. One owner described catastrophic internal damage (rods and metal scattered throughout, hole in the block) traced to a loose bolt left by a dealer's recall repair. Another's timing belt tensioner failed due to oil starvation. One replacement engine itself developed noise, suggesting installation or quality issues. A few owners reported early stalls at under 1,000 miles that dealerships couldn't reproduce. Throughout the narratives, the theme is consistent: oil leak, no parts available to fix it, engine dies, owner pays.

Failure modes owners describe
Oil Pan Seal Leak / Oil Leak
Oil leaks from the seal between oil pan and engine block, or from the oil pan area itself. This is the most common failure mode across the narratives and the subject of NHTSA recall 19V063000. Leaks can range from minor seepage to catastrophic loss of oil pressure.
When: Various mileages from 47,000 to 148,981 miles
Symptoms owners cite: Oil leaking onto ground when parked; Oil visible under engine/in engine compartment; Oil warning light illuminated intermittently or constantly; Low oil level requiring frequent refilling; Knocking/ticking noise in engine (as pressure drops); Engine overheating
Codes mentioned: NHTSA Campaign 19V063000, NHTSA Campaign 181, P0335 (Crankshaft Position Sensor - Oil Pressure related)
Repairs/costs cited: Oil pan seal replacement, oil pressure switch replacement. Some cases required full engine replacement ($6,000+ reported). Many dealers had parts unavailable for months after recall issuance.
Recalls/TSBs owners mention: NHTSA Campaign 19V063000 (Engine and Engine Cooling) issued February 2019 for 2010-2013 Tucson with 2.4L Theta-II engines. Recall status: remedy not available for extended period. Hyundai declined repairs on out-of-warranty vehicles citing they were not included in recall. Some owners denied coverage citing 'sludge build-up from neglect' and age/warranty expiration.
Engine Knock / Ticking / Clucking Noise
Audible knocking, ticking, or clucking noise from the engine compartment under acceleration or at idle. Often associated with low oil pressure from leaks or internal wear. Can indicate timing belt tensioner failure or valve train issues.
When: Typically occurs between 79,000 and 148,981 miles; one case at 101,000 miles
Symptoms owners cite: Knocking or ticking noise under hood; Noise worsens with acceleration; Clucking noise when starting or depressing accelerator; Check engine light may or may not illuminate; Noise persists after oil top-off or change; Noise progressively worsens over weeks/months
Codes mentioned: P0101 (implied - internal engine noise/CAM shift over advanced found on one scan)
Repairs/costs cited: Some repairs included valve gasket seal replacement and oil pressure switch replacement, but these were often unsuccessful as the underlying issue was the oil pan seal. Full engine replacement was ultimately required in multiple cases. One timing belt tensioner failure reported.
Recalls/TSBs owners mention: Related to recall 19V063000. Dealership diagnostics performed but parts unavailable for remedy. One dealer declined to diagnose due to diagnostic fee.
Engine Stall / Loss of Power / No Start
Complete engine shutdown while driving at highway speeds or in traffic, with no warning. Vehicle will not restart or restart only intermittently. Often occurs after oil has leaked out due to seal failure.
When: One case at 30,000 miles; most others 78,000-148,981 miles
Symptoms owners cite: Engine dies without warning while driving; No starter noise or fuel smell before failure; All warning lights illuminate after stall; Vehicle cannot be restarted; Cannot be jumpstarted; Requires towing; Stall occurs in traffic or on highway
Codes mentioned: Multiple warning lights (specific codes not documented in narratives)
Repairs/costs cited: Engine replacement required in all documented cases ($6,000+ repair cost). In one case, investigation revealed a loose bolt post-recall repair that caused catastrophic damage (rods, metal everywhere, hole in block and pan).
Recalls/TSBs owners mention: Recall 19V063000 issued but no remedy available when failures occurred. One case of denial of engine replacement citing sludge/neglect as cause. One owner not covered under warranty due to vehicle age. Hyundai denied involvement in some cases, citing vehicle not included in recall.
Engine Damage / Rod Knock / Blown Piston
Severe internal engine damage including blown pistons, connecting rod failure ('throwing a rod'), or catastrophic block/component failure. Usually results from prolonged oil starvation due to seal leak.
When: 78,000 to 140,000 miles
Symptoms owners cite: Loud metallic knocking/grinding from engine; RPMs increase suddenly, engine revs; Clicking noise from engine; All warning lights illuminate; Smoke emerges from engine; Oil spilled around engine compartment; Oil leaking before failure; Loss of power/stall
Codes mentioned: Internal engine damage diagnostics (specific codes not stated)
Repairs/costs cited: One case described finding 'rods and metal everywhere' with hole in block and pan. Another reported 'blown piston' after highway oil leak. All required full engine replacement. Metal contamination suggests extended oil starvation before failure.
Recalls/TSBs owners mention: Hyundai acknowledged loose bolt caused one post-recall failure. Manufacturer not notified in most cases. One dealer denied replacement citing sludge from neglect.
Timing Belt Tensioner Failure
Hydraulic timing belt tensioner fails, causing timing slip and catastrophic engine damage. One report attributes this to lack of oil pressure from the oil pan seal leak.
When: Mileage not specified in narrative
Symptoms owners cite: Engine stalls without warning; Requires towing to dealership; Vehicle stops working completely
Repairs/costs cited: Full engine replacement required. Owner notes oil level was correct at time of failure but lack of oil pressure (from leak) likely caused tensioner failure.
Recalls/TSBs owners mention: Hyundai shows no support or recognition of the issue per owner statement.
Oil Pan Seal Repair Part Shortage
Recall 19V063000 issued February 2019 but Hyundai failed to supply parts for the remedy to dealerships for months after recall issuance. Multiple owners reported being unable to schedule recall repair due to parts unavailability.
When: February 2019 recall issued; part shortage persisted through mid-2019 and beyond
Symptoms owners cite: Received recall notice but parts not available; Dealership confirms parts on backorder; Manufacturer unable to confirm when parts will arrive; Multiple calls to dealership over months yield no parts availability
Codes mentioned: NHTSA Campaign 19V063000
Repairs/costs cited: Owners could not have recall work done despite meeting recall criteria. No loaner vehicles provided in some cases. Owners responsible for vehicle operation while waiting for parts.
Recalls/TSBs owners mention: Recall 19V063000 issued February 2019 but remedy not available. Dealerships could not confirm availability timelines. Multiple complaints that Hyundai exceeded reasonable repair timeframe. One owner noted Hyundai failed to remedy in timely manner per NHTSA definition.
Engine Noise After Engine Replacement
After engine replacement under warranty or recall, replacement engine exhibited loud abnormal noise from underneath vehicle, suggesting improper installation or damage to exhaust/flex pipe.
When: Immediately after engine replacement service
Symptoms owners cite: Loud abnormal noise from underneath vehicle; Noise persists over time; Noise worsened over time
Repairs/costs cited: Issue reported to dealership but dismissed. Possible damage to exhaust system or flex pipe during installation. Repair incomplete.
Recalls/TSBs owners mention: Dealership dismissed concern without investigation.
Check Engine Light / Internal Engine Noise / Cam Timing Issue
Check engine light illumination with diagnostic scan revealing internal engine noise and cam shift over-advanced condition. Root cause unclear but indicates valve train/camshaft timing issue.
When: 131,000 miles
Symptoms owners cite: Check engine light illuminated; Diagnostic code: 'INTERNAL ENGINE NOISE SCAN FOR DTC MULTIPLE CODES CAM SHIFT OVER ADVANCED'
Codes mentioned: DTC Multiple Codes - CAM SHIFT OVER ADVANCED
Repairs/costs cited: Vehicle not repaired. Manufacturer not notified.
Early Stall / No Restart at Low Mileage
Engine stalls immediately after starting or during initial acceleration, typically at very low mileage (~600 miles) suggesting manufacturing defect or assembly issue.
When: Approximately 600 miles
Symptoms owners cite: Vehicle stalls when attempting to move forward from stop; Complete engine shutdown; Cannot restart engine; No warning signs beforehand
Repairs/costs cited: Vehicle towed to authorized dealer but failure could not be duplicated. District manager inspection found no cause.
