What stands out
Engine accounts for 50% of every owner complaint on file for this vehicle — the dominant problem area across 5 categories tracked.
Owners have filed 30 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.
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.
Follow the guidelines outlined in this bulletin to inspect and clean or replace certain components of the engine intake system accordingly during engine short block or sub-assembly replacement.

The failure pattern owners describe
The 2016 Hyundai Santa Fe Sport with Theta II engine suffers from a factory bearing defect tied to NHTSA Recall #20V-746. Owners describe sudden total engine failure, loss of power in traffic, and complete seizure—some without any warning light. The core issue: improper machining of the crankshaft during factory production left metal debris in oil passages, starving bearings of lubrication. The knock sensor detects low oil pressure from bearing wear, triggers limp mode, and logs P1326 code.
Failures occur across the mileage range: 63,000 to 172,000 miles. Some are sudden; others are preceded by weeks of intermittent check-engine light, smoke from exhaust, or rapid oil burn with no visible leak. One owner's dipstick read completely dry despite no low-oil warning light.
Dealers routinely deny claims, citing rebuilt title, prior rental status, or claiming the vehicle is not eligible per VIN—even when symptoms and recall number match exactly. One owner's claim was denied while the manufacturer acknowledged the prior owner had submitted a complaint for the same vehicle in January 2024. Hyundai activated a class-action settlement in 2021 offering lifetime engine warranty to affected owners, but dealers have blocked access to this coverage.
Post-replacement failures occur: one engine replacement failed within hours; another knock sensor was replaced twice post-engine replacement without fixing the problem. A 3-month dealer stay yielded no repair. In one case, the dealer failed to replace a required fuel line during engine replacement, causing fuel to leak onto the exhaust and ignite while the owner was driving—engulfing the vehicle in flames.

Failure modes owners describe
Connecting rod bearing wear and premature failure (Theta II engine defect)
Owners report catastrophic engine bearing failure leading to complete loss of engine function. Factory defect traced to improper machining of crankshaft oil passages, allowing metal particles to circulate and damage bearings. Knock Sensor Detection System (KSDS) detects low oil pressure from bearing wear, triggering P1326 code and limp mode. Failure can occur with little or no advance warning.
When: Occurs between 63,000 and 172,000 miles; some failures sudden with no prior symptoms; others preceded by weeks to months of intermittent warning light activity
Symptoms owners cite: Engine knock/knocking noise from engine compartment; Check engine light illuminates (flashing or steady); Loss of motive power, inability to accelerate above certain speed (10–60 MPH limp mode); Sudden engine stalling while driving or idling; Engine completely seized/locked up; Clicking sounds from engine; Rattling noise during acceleration or RPM increase; Oil burning/excessive oil consumption with no visible leak; Smoke from engine compartment or exhaust
Codes mentioned: P1326 (KSDS – Connecting rod bearing failure), Code TXXI (Theta 2 engine knock sensor detection)
Repairs/costs cited: Requires full engine replacement in most cases. One owner replaced knock sensor after getting P1326 code, but failure recurred; multiple dealer visits over 3+ months without resolution. Another owner's engine was replaced but bearing issue recurred. Independent mechanics confirm diagnosis; some dealers cite rebuilt title or prior rental status as reason to deny warranty coverage despite factory defect and active recall.
Recalls/TSBs owners mention: NHTSA Recall #20V-746 (Hyundai #198) addresses Theta II bearing wear. Class action settlement (2021) granted lifetime extended warranty on affected engines for class vehicle owners. However, dealers frequently deny claims citing: rebuilt title status, prior rental use, customer neglect, or claim vehicle not eligible per VIN despite matching symptoms and recall number. Some owners report manufacturer opened cases but declined assistance. One owner confirmed by Hyundai that prior owner had submitted complaint in January 2024 for same vehicle, yet claim still denied. Owners mention service bulletins exist but are difficult to locate or apply.
Excessive oil burning without external leak
Multiple owners report rapid oil consumption requiring frequent top-ups, with no puddles under the vehicle. Occurs independently or alongside bearing failure. One owner's dipstick was completely dry despite no low-oil warning light, leading to knock sensor trigger and engine damage.
When: Starting end of 2024 for one owner; develops gradually; another owner discovered dry dipstick after years of normal operation at 100K+ miles
Symptoms owners cite: Engine oil level dropping rapidly without visible leak; Abnormal odor from vehicle; No low-oil warning indicator illuminated; No oil pooling under vehicle
Repairs/costs cited: One owner reported at independent mechanic this is an ongoing Hyundai issue. No repairs documented; focus shifts to bearing failure when knocking begins.
Check engine light intermittency and delayed dealer service
Owners report check engine light turning on and off over weeks or months before catastrophic failure. Dealership refuses to service vehicle until light is flashing and engine has failed, creating safety hazard and loss of vehicle use.
When: One owner reported flashing light starting end of 2024, progressing to smoke from exhaust in April 2025; another at 32,000 miles
Symptoms owners cite: Check engine light illuminates intermittently, then constantly, then flashing; Smoke from exhaust; Sluggish acceleration
Codes mentioned: P1326
Repairs/costs cited: One owner took vehicle to Hyundai in April 2025; dealer refused service until check engine light was flashing and vehicle had stalled. Vehicle sat at dealer from 9/4/25 onward waiting for decision. Another owner faced 2+ month wait for initial inspection, then additional 2–3 months for repair; dealer 'too busy' and refused to answer calls.
Recalls/TSBs owners mention: One owner provided service receipts proving regular maintenance and noted KSDS system installed, but manufacturer (via dealer) denied claim for engine replacement.
Post-replacement engine failure and recurring defects
Owners report engine replaced under warranty or recall, but identical symptoms recur within hours to weeks. Vehicle towed back multiple times with knock sensor replaced, but failure continues; one vehicle spent 3 months at dealer without resolution.
When: One owner's replacement engine failed 2–3 hours after initial installation; another's knock sensor replaced twice post-engine replacement with no fix
Symptoms owners cite: Loss of power or inability to exceed 50–60 MPH after engine replacement; Check engine light flashing again; Hesitation and sluggish response; Vehicle fails to accelerate uphill
Codes mentioned: P1326
Repairs/costs cited: Engine replacement performed; knock sensor replaced twice; vehicle remained at dealer 3 months; no resolution. Dealer advised additional diagnostic testing needed but did not perform it or authorize repair.
Recalls/TSBs owners mention: Manufacturer opened case but did not authorize further repair.
Engine fire and fuel system integration failure post-replacement
After engine replacement under recall, original one-time-use fuel line not replaced as required by service procedure. Line developed leak; fuel dripped onto exhaust manifold and caught fire, engulfing vehicle in seconds.
When: Occurred after recall engine replacement
Symptoms owners cite: Fuel leak from fuel line; Fuel ignition on hot exhaust; Flames engulfing engine compartment and vehicle
Repairs/costs cited: Engine replacement procedure failed to replace required one-time-use fuel line, creating imminent fire hazard.
Engine failure without warning lights
Owners report sudden complete engine seizure or loss of power with no check engine light, oil light, or other warning illuminated beforehand. Vehicle becomes inoperable mid-drive with no opportunity to limp home or pull over safely.
When: Occurs at 70,000–150,000 miles without prior warning; one owner reports no warning until failure occurred
Symptoms owners cite: Complete loss of motive power while driving; Engine stalls or seized mid-maneuver (left turn, uphill, freeway); No warning lights illuminated before failure; No knocking or unusual noise reported in advance
Repairs/costs cited: Dealers diagnose bearing failure or engine seizure; vehicle requires engine replacement.
Recalls/TSBs owners mention: Manufacturer notified but often declines assistance, referring owner to dealer or NHTSA.
