Owners have filed 236 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.
Among the 19 model years of Hyundai Tucson in our records for engine problems, this one ranks #2 by owner-complaint volume.
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.
This TSB references the Op codes to use for claim submission and the Parts required based on the vehicle’s inspection results from TSB 22-01-023H-2 (DTC P1326 – Engine Bearing Inspection/Engine Replacement) or the latest version.
full bulletin at NHTSA ↗Hyundai is conducting a campaign to enhance the knock sensor software to detect abnormal engine bearing noise before potentially severe engine damage occurs. If abnormal engine bearing noise is detected, the Malfunction Indicator Lamp (MIL) will blink continuously, and the vehicle will be placed in Engine Protection Mode allowing the customer to drive to the nearest Hyundai dealer for diagnosis and repair. In addition, DTC P132600 will be recorded in the ECM. The vehicle can continue to be operated for a limited time in Engine Protection Mode, but it will accelerate slower and have a reduced maximum speed. Engine RPMs will be limited to approximately 1800-2000 RPM.
full bulletin at NHTSA ↗Certain 2016-2021MY Tucson (TL) 2.0L vehicles may experience continued DTC P1326 after the ECU update has been performed per TSB 22-01-028H-1 (or later) âENGINE MONITORING LOGIC (SERVICE CAMPAIGN 966)â.

The failure pattern owners describe
Owners describe a pattern of rapid oil consumption—burning 1 quart per 500–2,000 miles—with no low-oil warning light activation, followed by sudden engine seizure without pre-failure alerts. Loud knocking or rod-knock noises precede catastrophic failure, often on highways. Many found zero oil in the pan despite no visible external leaks and no prior warning. Owners report hesitation and loss of power during acceleration, especially entering traffic or highways, with engine revving high but vehicle creeping forward slowly or stalling entirely. Check engine lights flash, triggering limp-mode conditions. Multiple owners had spark plugs, ignition coils, and transmissions replaced repeatedly without resolving the underlying bearing issue. A few experienced engine fires; others dealt with catalytic converter clogging from oil intrusion. Hyundai denies most warranty claims, citing incomplete maintenance records, mileage over stated warranty limits, or alleged owner neglect—even when owners produced full service histories and Hyundai's own inspection records showed no problems months before failure. Owners also report long repair delays (4–6 months) without loaner vehicles and refusals to cover secondary damage like catalytic converters, despite root cause being oil consumption. Independent mechanics and some dealership techs confirmed this is a known defect pattern affecting multiple 2016 Tucson units, particularly the 1.6L turbo variant.

Failure modes owners describe
Excessive Oil Consumption
Engine burns or consumes oil at abnormally high rates, requiring frequent top-offs between service intervals. Owners report consuming 1 quart per 500–2,000 miles driven despite no visible leaks.
When: Throughout ownership; some owners notice it early (within first year or at 85k+ miles), others after 100k miles
Symptoms owners cite: Engine burning oil rapidly; No visible leaks on ground or driveway; Frequent need to add oil between scheduled changes; No low-oil warning light activation in many cases; Degraded power and acceleration over time
Codes mentioned: P1326 (knock sensor fault)
Repairs/costs cited: Owners cite combustion chamber cleaning (temporary fix only), engine replacement as permanent solution (~$5k–$15k); some qualify for class-action or extended warranty coverage
Recalls/TSBs owners mention: Hyundai extended engine warranty program (15 years/150,000 miles) for certain models; some denials citing mileage, maintenance records, or warranty expiration; Technical Service Bulletins issued recommending cleaning, oil consumption tests, and spark plug/ignition coil replacement
Engine Seizure / Rod Bearing Failure
Engine seizes suddenly due to bearing failure, often announced by loud knocking or rod-knock noise. Oil starvation or bearing degradation causes catastrophic mechanical failure requiring full engine replacement.
When: Typically 80k–120k miles; can occur without warning after minimal symptoms
Symptoms owners cite: Loud knocking or clanking noise from engine; Engine seizes and vehicle becomes inoperable; Oil level drops to zero or near-zero despite no visible external leak; Check engine light may illuminate shortly before or during failure; No warning from oil pressure gauge or low-oil light in many cases; Engine smoke or fire in some cases
Codes mentioned: P0300 (random misfire), P0302 (cylinder 2 misfire), P0304 (cylinder 4 misfire), P0420 (catalytic converter efficiency)
Repairs/costs cited: Requires full engine replacement; costs quoted between $8,300–$15,000 depending on labor and parts; some covered under class-action warranty or extended powertrain warranty if approved
Recalls/TSBs owners mention: Hyundai denies many claims citing insufficient maintenance records, mileage over warranty, or alleged owner negligence despite documented service history; some approvals through extended warranty program; multiple recalls issued for related defects in other engine families (Theta II)
Lack of Oil-Level Warning System
Engine oil drops to critical or zero levels with no activation of low-oil warning light, leaving owners unaware of impending failure. Combined with high consumption rates, this creates a dangerous condition.
When: Occurs alongside high oil consumption; owners discover zero oil only during diagnosis or breakdown
Symptoms owners cite: No low-oil warning light illumination despite critically low or empty oil pan; Owner discovers zero oil only after engine failure or during service; Lack of any audible or visual alert prior to catastrophic failure
Repairs/costs cited: No repair; this is a design deficiency. Owners must manually check dipstick frequently to avoid catastrophe
Recalls/TSBs owners mention: No recall or warranty extension addressing this specific design flaw
Hesitation and Loss of Power During Acceleration
Vehicle hesitates, lurches, or fails to accelerate smoothly when starting from a stop or merging into traffic. Engine revs but vehicle creeps forward slowly, or does not move at all for several seconds. Described as unsafe when entering highways or intersections.
When: Early in ownership for some; persistent issue lasting years for others. Occurs at stops, low speeds, and highway merges
Symptoms owners cite: Hesitation or lag when depressing accelerator from complete stop; Engine revs to high RPMs (5,000–6,000 RPM) but vehicle creeps forward slowly or not at all; Lurching forward unpredictably after delay of 5–10 seconds; Loss of power on highway merge or during acceleration; Issue repeats intermittently or becomes persistent
Codes mentioned: P1326 (knock sensor), Transmission fault codes (DCT-related)
Repairs/costs cited: Dealerships perform DCT (dual-clutch transmission) software updates; turbo replacement in some cases; issue persists despite multiple repairs. Some owners forced to replace transmission
Recalls/TSBs owners mention: Recall 16-01-038 (DCT logic update); recall 16-01-057 (additional DCT update); some dealers dismiss issue as 'design of the dual clutch transmission' and state nothing can be done; no engine-specific correction offered despite knocking/bearing involvement
Engine Misfiring and Flashing Check Engine Light
Engine misfires on one or more cylinders, triggered by knock sensor faults or bearing degradation. Check engine light flashes, creating limp mode and sudden loss of power.
When: Can occur at any mileage; often appears after 85k–120k miles but reported as early as 77k
Symptoms owners cite: Check engine light illuminates or flashes; Engine misfires audibly; Rough idle and stalling; Vehicle enters limp mode (reduced power, max 30 mph); Spark plug and ignition coil replacement does not resolve issue; Compression test shows cylinder failure
Codes mentioned: P1326 (knock sensor fault), P0300 (random misfire), P0302, P0304 (cylinder-specific misfire)
Repairs/costs cited: Spark plugs and ignition coils replaced multiple times without lasting fix; compression test reveals internal engine damage; full engine replacement necessary
Recalls/TSBs owners mention: Hyundai extended warranty program covers replacement under certain conditions; some denials based on warranty expiration or mileage; Technical Service Bulletin references provided to owners by independent mechanics indicating known defect
Oil Intrusion into Catalytic Converter
Excessive oil consumption causes oil to enter the catalytic converter, clogging it and causing converter failure. Vehicle loses power and throws catalytic converter codes.
When: Follows prolonged oil-burning period; catalytic converter failure occurs after 100k+ miles in some cases
Symptoms owners cite: Catalytic converter efficiency code (P0420); Check engine light; Loss of power and slow acceleration; Vehicle stalls or enters limp mode; Converter needs replacement
Codes mentioned: P0420 (catalytic converter efficiency), P0300 (misfire related to converter clogging)
Repairs/costs cited: Catalytic converter replacement ~$5,000 OEM; some owners quote independent shops at lower cost; Hyundai refuses to cover, claiming engine and exhaust are unrelated; owners must file for reimbursement with no guarantee
Recalls/TSBs owners mention: Hyundai denies responsibility, stating catalytic converter is outside warranty coverage period (8 years/80,000 miles) and engine/exhaust issues are not connected; refuses to cover despite root cause being oil consumption
Engine Overheating and Head Gasket Failure
Engine overheats without warning; head gasket blows, requiring $12,000+ replacement. Coolant level drops despite no visible leaks.
When: Reported after a few months of ownership for some used-car buyers
Symptoms owners cite: Engine overheating warning light or alert; Coolant level drops rapidly; No visible coolant leaks; Inability to restart after pulling over; Loss of power on highway
Repairs/costs cited: Head gasket replacement ~$12,000; one owner quotes obtained ~$12,000 for complete repair
Recalls/TSBs owners mention: No warranty coverage mentioned for this failure mode in narratives
Cracked Exhaust Manifold and Turbocharger Assembly
Exhaust manifold and turbo assembly develop cracks, allowing exhaust gases (including carbon monoxide) to leak into cabin. Poses risk of carbon monoxide poisoning and reduced engine performance.
When: Diagnosed after engine performance issues reported in prior years
Symptoms owners cite: Reduced engine power and performance inefficiency; Exhaust manifold and turbocharger assembly cracked (confirmed by diagnostic testing); Engine performance issues
Repairs/costs cited: Diagnostic testing cost ~$200+; cracked components identified; repair cost not provided in narrative
Recalls/TSBs owners mention: Hyundai corporate refused warranty coverage despite dealership diagnosis; no TSB or recall mentioned for this specific failure
Engine Failure Due to Missing or Loose Oil Drain Plug
Oil drain plug becomes missing or loose during service, causing complete oil loss and engine seizure after hundreds of miles or weeks of normal driving.
When: Approximately 3 months after oil change service
Symptoms owners cite: Oil pressure warning light illumination while driving on highway; Engine seizes immediately upon stopping; Vehicle cannot restart; Oil drain plug found missing upon dealership inspection
Repairs/costs cited: Engine replacement covered under warranty (oil drain plug issue attributed to maintenance, though owner disputes timing and mechanics)
Recalls/TSBs owners mention: Engine replaced under warranty; dealership suggested plug was improperly installed at prior service location, though owner questions this hypothesis given 3-month delay

Hyundai tucson engine the vehicle is burning excess amounts of oil. The rate of engine oil loss is over one quart per 500 miles. My mechanic tells me his evaluation is the vehicle's turbo unit causes the engine to run very hot, and the internal seals are breaking down, causing oil to mix with the fuel. The solution is an engine rebuild, which will cost over $3,000. Such a rebuild will result in…
Engine knocking and loosing power under acceleration.
At the end of November 2021, my oil change light came on, which was odd because I was not due for an oil change. Brought the car in, they changed my oil and the light was gone. Barely a week later, the oil light came on again. I had some guys at work check it and they said I barely had any oil. I scheduled another appointment but never made it. I was driving on the highway when my car…
I was at a stoplight waiting to turn right. When there was a safe break in traffic I began the right turn, but the engine made a clunking noise and stopped accelerating in the middle of the road. At this point, cars were getting close to me and my car wasn't speeding up, so I turned on my hazard lights and managed to inch onto the shoulder. I had my 5 month old baby in the car with me, so his…
This evening me and my fianc were driving 45mph down hill on a straight road to get christmas gifts, and all of a sudden out of no where the engine just died/stalled (no warning/dashboard lights). Thank god we were able to coast into a gas station and get off the road safely. The car wouldn't even turn over, so my fianc checked the oil and it was low. The car doesn't leak oil and we do oil…
