Of the 5 model years of Hyundai Palisade we track for engine problems, this one carries the most owner complaints on file — 69.
Owners have filed 69 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.
The failure pattern owners describe
Buyer takeaway: A 2020 Palisade with this engine can consume a quart of oil every 1,000 miles or less, often without any warning light, putting you at risk of engine seizure on the highway. Many owners report catastrophic engine failure, fires, and unexpected stalling; Hyundai's warranty typically excludes oil-consumption damage and requires expensive dealer service to qualify for help.
Owners describe excessive internal oil consumption in 2020 Hyundai Palisades, typically burning 1–5 quarts per 1,000–3,000 miles with no dashboard warning. The oil level drops far below the minimum dipstick mark—sometimes to completely empty—without triggering a low-oil light. By the time an owner checks the dipstick, the engine often has zero oil left, and some engines begin knocking, stalling, or grinding.
Owners report engine stalls at traffic lights, sudden loss of power at highway speeds, and multiple stalls within minutes—all without advance warning lights. One owner's 16-year-old daughter was left stranded when the engine failed and caught fire; another owner's vehicle caught fire while being driven to the dealership for diagnosis.
Hyundai dealerships diagnose internal valve-seal leakage or piston-ring wear. The manufacturer's protocol requires proof that the engine consumes over 1 quart per 1,000 miles before offering help. Even then, they perform a combustion-chamber cleaning ($700) that owners report often fails, ultimately requiring full engine replacement ($13,000+). Warranty coverage is frequently denied if you had service done outside a Hyundai dealership, if mileage exceeds 100,000 miles, or if the warranty terms exclude oil-consumption damage.
One owner reports oil-filter housing cracking, with oil pooling beneath the vehicle. Another describes their dealership accidentally using wrong-weight oil (0W20 instead of 5W30), burning through six quarts in 3,000 miles. Owners cite these engines as a known, unresolved defect across the Hyundai lineup, with class-action litigation reportedly underway.

Failure modes owners describe
Excessive oil consumption without warning lights
Engine burns 1–5 quarts per 1,000–3,000 miles depending on driving conditions. No low-oil warning light illuminates even when oil becomes critically low or depleted entirely. Owners report checking dipsticks and finding little to no oil on the stick after short intervals (300–2,000 miles post-service). Issue commonly attributed to internal combustion-chamber oil leakage, piston-ring wear, or valve-seal failure.
When: Mileage varies widely: 25,000 miles in one case, but most frequently reported from 65,000 to 100,000 miles. Some owners report onset within first year or before first scheduled service.
Symptoms owners cite: Engine knocking, rattling, or tapping sounds; Rough idle, stuttering, or surging at traffic lights; Shuddering or vibration when accelerating or at stop; Engine stalling without warning, especially at traffic lights or while slowing; Loss of power or inability to maintain highway speeds; Blue smoke from exhaust on cold start; Check engine light or misfire codes after stalling
Codes mentioned: P0303 (cylinder misfire), Fuel pressure code, EGR or CVVT codes (oil-starvation related)
Repairs/costs cited: Dealership oil-consumption tests require 1,000-mile intervals; if consumption exceeds 1 quart per 1,000 miles, dealership may perform engine carbon/sludge cleaning (reportedly $700) or combustion-chamber cleaning. Many owners report these steps do not resolve the issue. Full engine replacement ($13,000–$20,000+ in owner estimates) is the final step after failed cleanings; one owner reports replacement engine was installed after 44 days. One dealership accidentally substituted 0W20 for recommended 5W30 oil. Owners cite valve-seal failure, piston-ring defect, and OCV (oil control valve)/CVVT solenoid clogging as root causes. One service replaced the OCV/CVVT solenoid (May 2025 service record); catastrophic failure followed shortly after.
Recalls/TSBs owners mention: Hyundai requires proof of 1 quart consumption per 1,000 miles before warranty action; thresholds vary. Owners report Hyundai denying coverage if maintenance performed outside dealership, if vehicle mileage exceeds 100,000 miles, if extended warranty does not cover oil consumption, or if vehicle is out of powertrain-warranty window. One owner reported Hyundai offered 50% of repair cost. No formal recall identified in narratives, though owners reference class-action litigation and widespread forum discussion of 'EDI' or 'GDI' engine issues across Hyundai model lineup.
Catastrophic engine failure with fire risk
Engine loses all oil pressure suddenly or after prolonged low-oil operation, leading to internal bearing and connecting-rod damage. Engine compartment fills with smoke or catches fire; in two narratives, flames erupted from engine bay. Mechanical failure occurs without warning—engine stalls, metallic grinding noise, loss of power mid-drive. One engine was reported to have multiple holes in the block. Fire hazard emerges during or immediately after failure.
When: Typically occurs after months or years of unaddressed excessive oil consumption. Mileage range: 8,500 miles (early failure with cylinder breach), 92,000–155,856 miles (late-stage failures). One vehicle caught fire while being driven to dealership for oil-consumption testing.
Symptoms owners cite: Sudden loud metallic grinding, knocking, or crunching noise from engine; Immediate loss of power and stalling; Cabin fills with smoke; Oil leak appears suddenly without prior external leak; Engine compartment fire or smoke ejection
Repairs/costs cited: Engine replacement required. In two fire cases, insurance covered fire damage but not the underlying engine defect. One owner faced $13,000 repair estimate (fire damage only). Dealership statements include 'no known cause' and refusal to cover failure if services were performed outside dealership network. One narrative notes owner is 'pretty sure that's not how it works' regarding dealership refusal based on external service history. One towed vehicle (May 2025 fire case) remains at dealership with no resolution as of complaint date.
Recalls/TSBs owners mention: Hyundai denies coverage citing external service history or warranty lapse. No manufacturer buy-back or goodwill offer documented in these narratives. Owners report frustration that Hyundai 'shrugs it off' or states 'they unfortunately can't do anything.' One owner notes a class-action lawsuit is ongoing for 2020 Hyundai Palisades.
Engine stalling during normal operation without warning lights
Engine unexpectedly shuts off while driving at freeway speeds, during acceleration, while stopped at traffic lights, or while slowing to stop. Power steering and braking remain functional after stall, but no warning lights illuminate beforehand. All narratives confirm low or zero oil as the cause; one case confirms cylinder #4 failure requiring replacement, then cylinder #2 failure requiring full engine swap.
When: Occurs unpredictably after oil-consumption intervals. One early case at 13,700 miles; most commonly reported between 50,000 and 100,000 miles. One recent case reports seven stalls within a 5-minute drive at 25,000 miles.
Symptoms owners cite: Engine shuts off without warning at traffic lights, during acceleration, or on highway; No low-oil light or check-engine light prior to stall; Check-engine light may illuminate after stall; Engine restarts after shutdown; Loss of power-steering assist and normal braking during stall
Codes mentioned: P0430 (catalyst system efficiency below threshold), P0500 (vehicle speed sensor malfunction)
Repairs/costs cited: One case required cylinder #4 replacement, then cylinder #2 replacement, then full engine swap. Another required full engine replacement. Owners note dealership inability to reproduce issue during test drive, delaying diagnosis.
Recalls/TSBs owners mention: Hyundai acknowledges low oil as cause but does not proactively address underlying oil-consumption defect. Warranty claims often denied due to mileage, external service, or coverage gaps.
Oil filter housing leak
Oil filter housing cracks or develops seal failure, allowing oil to drip from engine compartment. One narrative reports leak worsening from small residual spots to stains the size of a paper plate within 50 miles of driving. Another notes cracking occurs in cold weather.
When: Post-service at dealership or in cold weather. One case reported after routine oil-change service; another noted in cold-weather conditions.
Symptoms owners cite: Oil spots on driveway under parked vehicle; Spots grow larger and more frequent with continued driving; No warning lights
Repairs/costs cited: One owner sourced the replacement oil-filter-housing part independently and paid an independent mechanic for replacement. Dealership stated it is a known issue but not covered by warranty.
Recalls/TSBs owners mention: Dealership advised 'known issue' but denied warranty coverage. No recall or TSB mentioned in narratives regarding filter-housing failure.
Internal valve-seal and piston-ring failure
Diagnostic testing reveals valve-seal leakage or piston-ring wear allowing oil to enter combustion chamber. One case confirms piston-ring failure causing no compression in cylinder #1. Another identifies internal valve-seal leakage. These defects force oil past the rings into the combustion chamber, where it burns rather than circulating.
When: Diagnosed after months of unexplained oil loss. One case at 31,000 miles; others between 30,000 and 98,000 miles.
Symptoms owners cite: Excessive oil consumption with no external leaks; Blue smoke from exhaust on start-up or at idle; Check engine light (misfire or lean codes); Engine overheating without warning; Shaking or rough idle after oil is added
Codes mentioned: Misfire codes (cylinder-specific)
Repairs/costs cited: Hyundai dealership diagnosis includes combustion-chamber cleaning attempts before engine replacement. One owner reports voice recordings confirming diagnosis of faulty piston ring. Cleaning often does not resolve the issue, necessitating full engine replacement.
Recalls/TSBs owners mention: Hyundai directs owners to oil-consumption test protocol; if threshold is met, engine cleaning is offered before replacement is approved. One owner notes Hyundai's warranty exclusion for oil-consumption damage despite the defect being manufacturer-caused.

Common questions
How serious is the engine problem on the 2020 Hyundai Palisade?
It's a documented issue but not catastrophic. 69 complaints have been filed. Repairs average $3,100 and most owners catch it before it causes a breakdown.
At what mileage does the engine typically fail?
Across the 8 complaints that reported odometer mileage, most engine failures cluster between 13,700 and 89,000 miles, with the median around 30,000. A quarter of owners report trouble before 13,700; a quarter make it past 89,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $3,100 for engine repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to engine?
No active recalls currently cover engine issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
